newbie over whelmed
john-d - 16/1/13 at 08:06 AM

Hi all, cool sitr you have here.

Long story short:
24 and owned a few performance cars
Just sold an e46 m3
Want something a bit more special and personal
Young child so spacing cost over a period is helpful
Single garage
Reasonable welding and craft skills
Many mates in machine shops etc
Wanting sub 4 second 0-60
Lean towards vauxhall as its what i know best
Traditional lotus 7 style wanted

Well basicly thats that, the site, im sure is a hive of info but at my early stage is really too much at once.

Now i bought a book on ebay which suggests using a mk1 escort (good luck finding one) and even suggests one can be had for £25 lol obviously this is outdated.

What is the best plan/kit for what i want? Really fancy a home made jobby but am flexible.

Probably have around £4-500 a month for parts most the time but obviously i dont want to spend £££££. Id rather make then buy someones.


johnemms - 16/1/13 at 08:14 AM

Either a part built or save for a cheap IVA'd one is my advice


john-d - 16/1/13 at 08:17 AM

As pretty much stated in my lost post i want to make my own not a one somebody has possibly bodged together. I will either buy a kit to assemble or make my own chassis using plans...


NigeEss - 16/1/13 at 08:22 AM

Hello and welcome to probably the best fountain of knowledge on the web.

You have picked up Uncle Rons book, Escorts are now like hens teeth. There's a newer book by Chris Gibbs/Haynes
which bases on a Sierra which are also now scarce. Modern thought leans towards Mazda MX5 or BMW 3 series of
there see still plenty.
Plenty of kit manufacturers, MK, Saturn, MNR, Tiger etc or start from scratch.
A built car will generally cost less in the long run.

Good luck and enjoy whichever route you choose.

Ps: put your location in your profile, almost certainly someone local who is willing to meet and assist.


snapper - 16/1/13 at 08:31 AM

The new book is the Haynes Roadster by Chris Gibbs
You can buy the chassis pre built or cut in flat pack or you can be a real soldier and cut it from the tube
Me, I would buy a chassis, wishbones and hubs then get the body work and a donor vehicle
The rest is generic and you can pick stuff up as you go along


jossey - 16/1/13 at 08:32 AM

As nige said go for something without the escort n sierra if you can help it.

If you want to do it in stages ten I would suggest either buy a part built manufacturers chassis n bits not home built n build that up or a new chassis from the likes of mk, mnr, tiger when you know what engine you want. Eg road use n track? Bike engine or car as all of those kits have huge potential with specific set ups like don't put a v6 or v8 in a tiger avon etc.....

If I was to start again I would go car engine not bike.... I would use the tiger still as its great for bth road n track..... I would buy new bits where poss. I would have bought a running engine from a car eg zetec or Saab or something.

God luck and I hope to see you build something.

Buy a few more books like the build a sports car for 250 the new one and what ever manufacturer u choose.


john-d - 16/1/13 at 09:00 AM

Thanks for the replies.

I will have a look for the gibbs book.

Im not against buying as said a manufactured chassis, i like the sound of buying flat pack already cut.

Im probably going down the c20xe, c20let or z20let route. Probably with a type 9 box. What sort of bhp is needed for sub 4 sec 0-60.

It will be a road car not track.


sdh2903 - 16/1/13 at 09:18 AM

To get sub 4 secs with a heavy car engine is going to need a lot of power, well in excess of 200bhp I would have thought.

I would say sub 5 secs maybe a better target to aim at.

I know you say you want to build but buying a complete one cuts out all the expense and hassle of IVA and registration. there's nothing stopping you from stripping it down and fully rebuilding to your spec and standards.

If you are adamant about the sub 4secs you need to be very light, in which case have you thought of using a bike engine? A good zx12 or late zx10 engine will give 170Bhp out of the box and a one can be had for a grand if you look about. I will admit to knowing nothing of the vauxhall engines but I imagine would still be reasonably pricey to get up above 200hp?


sdh2903 - 16/1/13 at 09:22 AM

ah bit of googling shows the z20let is the turbo engine, bit more tweakable I guess


john-d - 16/1/13 at 09:38 AM

z-let is cheap to get to 300bhp mate, although i doubt a type 9 would take that power. I always thought of bike engines as a bit highly stressed?

I see the point about avoiding iva which seems good indeed


SCAR - 16/1/13 at 09:43 AM

Real world driver with sub 4 secs 0 to 60, forget it you havent got anywhere near enough money.
Sub 5 sec and you might get there (talented, frugal, lucky?) and you can always tell everyone its sub 4 as they wont be able to tell the differance (unless you take them to Santa Pod.)
I would think you need a very very light weight car with a bike engine of about 200bhp or a light weight car with 400bhp The engine alone installed and running will cost 4k+.
Then you need to find the grip, probably 4wd, oh then you need more power.
A couple of things to be aware of
1. A kit car will feel and be much quicker than most tin tops.
2. All figures reduce in the pub except the bhp ones which increase.
3. You will get mixed advice on forums (usually good on here) and you will need to filter out what you think is correct
4. Find someone with a car you like and blag a ride before you commit to anything
5. Add 1 sec to any 0-60 times anyone quotes unless they have a santa drag strip print out
Good luck let us know how you get on
Cheers

that'll depend on how heavy you make it


but if your looking for that sort of performance you should consider the darkside (i.e. bike engines)

sdh2903 - 16/1/13 at 09:54 AM

The Iva is 500 quid of your budget straight away as well as a day of your time etc. and that's if you pass first time. Then you have to deal with the Dvla which can be hit and miss to say the least. Plus all the dvla offices are closing so even more problems as everything to be done at Swansea.

I'm not saying don't build as I loved building mine and I would (and will) do it again. But it is loads easier, quicker and generally cheaper to buy one.

Bike engine vs Car engine will open up the age old debate on here just do a search and grab some popcorn.

I have a bike engine in mine, an older carbed R1 engine with maybe 130 hp at the wheels and it goes like stink, by far the quickest thing I've driven. I've never had an m3 though to compare. Yes they are kind of highly strung but for a 'toy' car they are superb.

Find someone local with a car engined car (CEC) and someone with bike engine (BEC) and try and get a run out. that will make up your mind for you.


john-d - 16/1/13 at 10:17 AM

been browsing some threads on here, seen some mighty corroded chassis. Think im more up for building my own, its not a rush project. Its some thing to keep me entertained so can take as long as it wants meaning if something costs a lot then ill save up till i can afford it.

The m3 did 5.2 sec 0-60 which felt fast at first but i soon grew used to it.

A mate of mine has a spartan kit car with a 1300 triumph engine in it, 80 mph in that is terrifying so i understand the tin top comment.

Guess the place to start is a gibbs book then work out whats what. My main worry is finding an axle and box to take a let engines torque.


jossey - 16/1/13 at 10:19 AM

I know this will start an interesting convo/ argument but if your going to iva just get a car engine I have just started looking at reverse boxes n they will cost me around £500 with a new prop.

You need reverse for iva.

When I iva mine ill dump a cheap Zetec in it which may fall out later on.

I'm a bike engine guy myself but its a world of pain for iva me thinks.

People like adi thorp may disagree but that's a forum for ye.

Bikes seem to be good for great 0-60 and even to 100 on a track but not very particle for road use.

I've been in some fast cars with both bike engines n laptoprobs c20xe n the bike engine just sounds quicker not sure on actually lap time difference.

Defo get a track ride in both :-)

0-60 in under 4 seconds isn't THAT difficult to achieve. You certainly don't need 200bhp to do it in a bike engined car.

My tyres aren't exactly representative, but i've seen some fairly lowly sevens on good road tyres doing 2.3 second 64ft times.


john-d - 16/1/13 at 11:27 AM

I dont see it that impossible, maybe a bit over engineering of parts will be needed for a haynes kit but surely its the same basic principle as a caterham


mcerd1 - 16/1/13 at 12:17 PM

caterhams are very light compared to some anyway (BEC locosts can be even lighter though )


they quote the classic as 6.5s to 60 (525kg, 105bhp / 95ft.lbs from a 1.4 K series)

the top spec road sport as 4.8s to 60 (550kg, 175bhp / 139ft.lbs from a 2.0 duratec)

with the R400 at 3.8s to 60 (515kg, 210bhp / 150ft.lbs from a 2.0 duratec)


if your building car using parts from any of the common donors they'll be a fair bit heaver than the (expensive) caterham equivalents (alloy hubs etc)
never mind that the caterham engines are all fairly light weight all alloy ones, so you could find yourself starting with a bit of a weight disadvantage…

assuming you can get the power to weight you may struggle to find the grip to be able to use it
(I know some folk have run there fastest 1/4 miles with a bag of sand in the boot to get more grip off the line! )


not saying its impossible, but it could cost more than you think - IMHO its better to build it with a more realistic goal and upgrade it later as an ongoing project


SCAR - 16/1/13 at 12:40 PM

Its not impossible, its just expensive to achieve
Be good if someone can post on here what they have that has sub 4 sec 0 to 60 (with proof and not a bloke down the pub or "it used to be 6 secs before I rebuilt it so must be sub 4 sec now"
There is a massive differance between say 3.8 and 4.8 and I would expect a car engine would need to be turbo'd and probably 4wd.
We have a fuel injection rebuilt Rover 3.5 with megasquirt engine management in a seven that weighs about 700kg all up 200bhp but lots of torque, geared to do 0 to 60 runs in second gear so no gear changes required probably doing low 5's.
We now have a 4.6 to drop in which should give us another 30bhp but lots more torque. I doubt we'll see better than 4.5
Caterham r400 3.8 secs 420bhp per ton and £33,000

2.37seconds to 64ft + O-level maths = 0-60mph in 4seconds

FYI Adam is too modest, I google his times to 64ft and found one at 2.08secs, which equates to 0-60 in 3.07seconds, and he only has a gsxr1100 (heavily breathed upon).

All calcs based on a constant acceleration calculation and no gearchanges.

BEC's rule.


smitht82 - 16/1/13 at 01:07 PM

Hi John,

I'm an ex Vaux nut and had an SRI Turbo Z20LET with 298bhp and 380 Torque. I now have a MK Indy with a Fuel Injected Yahama R1 engine and must say it makes the Astra feel like it was standing still. Mostly how close to the floor and open to the elements you are. The engine is where the difference will lye in your experience of the car as the BEC is so light and agile, but its the noise it makes.

Good luck in your decision!


john-d - 16/1/13 at 01:17 PM

Is there any books/guides on building a bec? I like the sequencial box tbh but worry about the engineering side of things

Everything you need to know is on this site, I bought a part finished MK with a ZX9R engine for £1800, stripped it down completely and rebuilt it my way, you could check my Photo Archive for an insight, but if you need to know anything during the build you can find it here, using the search function, or simply ask


Proby - 16/1/13 at 03:10 PM

My factory built F27 Blade is quoted at 4 secs 0-60. I have an original magazine feature/article back from 1999 (I think it is, without digging it out). They carried out the 0-60 test on a number of vehicles for the feature, according to the 'official timed figures' my car (in factory spec) hit 60 in 4.07. That was in controlled conditions. At the moment I have maybe 125bhp?

EDIT: I'm now going to dig the magazine out!!!

[Edited on 16/1/13 by Proby]


john-d - 16/1/13 at 03:44 PM

So the concensus is a bike engine is better/faster/lighter


SCAR - 16/1/13 at 04:47 PM

"which equates to 0-60 in 3.07seconds"

Thats faster than a 627bhp 6 litre V12 Mclaren F1 (550bhp per ton)


mcerd1 - 16/1/13 at 04:48 PM

in general they are lighter - the right bike engine and a super lightweight build (read: no windscreen, no carpet...) will give you a very quick car


faster - (0-60 see above) as for the top speed of any se7en is not going to win you any braging rights in the pub, the aerodynamics are slightly worse than a brick...


'better' depends on whats most important to you - some people like crusing along with lazy V8, some like a revy 4 pot, some like smooth 6 pot and others like the screaming mental bike engine (rear axle gearing obviously has an impact on this too) - which one are you ?
as above the only way to find out for sure is to try them (at least get a ride in one of each)

Get ye arse to the next track day n passenger a few different cars ten decade that's how I choose the tiger avon bike engine.

No way I would use it on road though...

Sounds silly but im not sure i like that


unijacko67 - 16/1/13 at 06:33 PM

Go and buy a Reliant Kitten then put a big engine in it, light and fast, 0-60 in about 3 years at this rate.!!!!!!

Good luck with the search.


scutter - 16/1/13 at 06:53 PM

My 7 records 0-60 times between 4.9 and 5.1 with just under 200 bhp.

I wouldn't bother looking for MK2 escorts, but the main parts you need are on the bay all the time. Currently on Turbosport (you may need to log in) is a LSD/disc braked MK2 axle for £200, that and a quick rack are the only really big bits you need.

That axle with a BEC in my friends RGB spec car easily hits 60 in under 4. What I'm trying to say is if you want a light car then the parts are about.

Regards Dan


john-d - 16/1/13 at 07:04 PM

How do you use axle like that with a bike? Wouldnt it be chain drive?


scutter - 16/1/13 at 07:19 PM

Mid engined cars tend to be, but front engine rwd have a propshaft adaptor to replace the front sprocket. This goes to the axle via a reversing gearbox normally (the costly bit)

Regards Dan.


john-d - 16/1/13 at 07:22 PM

So the engine is fitted sideways so to speak?

Explains a fair bit hmmnn


froggy - 16/1/13 at 07:38 PM

A mate of mine went and hired a seven for the day and decided it wasn't for him . As he put it " I spent a couple if hundred but it saved me a year of my spare time and 10k .

Its also faster than a 600bhp/tonne Westfield on pretty much the same tyres. Its all down to gearing, weight distribution, suspension setup and power curves. I sacrifice a bit elsewhere and gain in low speed traction and power spread.

Thats with 135bhp at the tyres in 450kgs.

john-d - 16/1/13 at 09:05 PM

Starting to feel pretty damn set on building one myself now... Whats the worst that can happen? I end up with a scrap chassis and sell on the rest if i fail.


BangedupTiger - 16/1/13 at 09:09 PM

I dont think you'll cram an LET in, and if you could then i'd got for the LEH.

Personally, i'd go for a Z16LER, smaller, lighter and can still acheive silly power.


john-d - 16/1/13 at 09:12 PM

Going buy the gibbs book then make myself a decent bench up.

I will have a mate pre cut and angle all the box section and label it up using his band saw at graft.

Tack together the frame minus engine mounts and then take it from there, bike engine is tempting as i could probably get a crashed r1 or similar for peanuts, id still want 200bhp + so would require a tinker, sure that could be done at a later stage.

Leh an astra vxr jobby? if so they are expensive. As are the corsa vxr engines which i assume you mean.

I can buy a full astra coupe turbo with a z-let for £2k, id make a load back on breaking it.

A let is exactly the same size as a c20xe? Apart from the obvious turbo on the side rather than a huge 4 branch.


parkiboy - 16/1/13 at 09:52 PM

I'd go for a bike engined one if its speed your after, don't let anyone tell you they can't be used on the road, I have had no problem using mine on the road, people complain saying the clutch its to sensitive in traffic, the clutch is more forgiving than any paddle clutch I've used on other cars and if you use the correct diff ratio (I'm using 3.14) it is fine on the motorway.

I've been out in a few CEC's one being a 200bhp Zetec MK and yes that was bloody quick, but driving a BEC feels a lot more special in my opinion, not even for the speed, its the the high revving, the noise, the sequential shifting. I wouldn't change mine for anything even despite the problems I have had (due to being unfortunate and buying a bad build)


parkiboy - 16/1/13 at 09:55 PM

And just to add you don't needs target of 200bhp for a BEC, as they are about 100-150kg lighter on average. You want to be looking more at power to weight.

If you do go for a car engine haven't you considered for F20c? 240bhp as standard.

[Edited on 16/1/13 by parkiboy]


BangedupTiger - 16/1/13 at 09:59 PM

Depends on how far you want to tune it, an LET is a good engine, but the LEH is a fer better engine. and not that expensive

If you want a fast car then a good option is an M3 engine in a 7, it's a great engine. My car is 700 kg and will do 0-60 in about 3.5, 0-100 in 7.5. It still scares me, in a good way :-)

gaz_gaz - 17/1/13 at 06:56 AM

Got an s54 engine with 70k on it.
All the problem areas already done such as head gasket. Conrod recall and vanos.
Still in the car with full 1 owner history.

If you fancy going really fast.

It's the E36 M3 EVO engine, and yes it does. Vanos looks healthy as far as I can tell, valve clearances shouldn't be that hard to do (not that I've done them mind). The first M3 engine I had did have a faulty vanos and died from a spun shell so I take your point, but fingers crossed this one is good. Should be relatively unstressed in a 7.

It is a heavy lump though, I keep changing my mind on the "perfect" engine for a 7 but today I reckon if starting from scratch I'd be eyeing up an S2000 engine.


dhutch - 17/1/13 at 12:44 PM

I bought my car aged 21 (now 25) after spending a lot of time considering bike engine, car engine, building, buying and ended up buying a secondhand and have not regretted it, but my requirments of the car where diffrent as I had come to the conclusion I wasnt patience enought to deal with a build.

Work out what you want to do with the car and get yourself some passenger rides.
- I wanted to have some I could have fun in on track, but also use on the road in the summer. I have dont trackdays in it, but also taken the girlfreind to the middle of france for a week, and now use it for autotesting. Racing in a series didnt appeal, although my housemate at uni and also member on here built a locost and raced it in the 750mc, which is another option, as are sprints/hill climbs and says at santapod.

Have a look at a few second hand or members cars, and test drive them if you can, even if looking at building it will give a feeling for what others have done and what you can expect.

The cvh in mine is putting out I think maybe around 130brake, car weighs 540kg, standard radtio type 9, open live rear axle, 185X60R13's all round, and it certainly doesnt feel slow to 60. Driving around town, out of roundabouts, when autotesting it feels seriously quick, and although acceration drops off once you get abot 60, 70-80 on the motorway of backstraight feels like 110.

My current housemate has the supercharged JCW mini which claims mid 5's to 60 and isnt driven lightly and when when the topic came up he suggested that 'the kitcar would proberbly have have it to 100, but the mini after that' and while im fairly confident I would have it to 60 the kitcar tops out not much beyond 100, which sort of shows how diffrent the feel. As I said, you need to get yourself in one! Nothing quite like feeling the back end squirm as you boot ir out of a damp roundabout! Gokart.


Daniel
