im thinking off building a bike engined kit car.
im not looking to start a war. im looking for peoples experiences if you own a BEC Chassis and was to do it again what would you change what would you
keep the same.
i dont really have a budget which i know is dangerous lol but the car will be mainly a track car but i will iva and road register.
i currently have a westfeild mazda turbo. but need to scratch my bike engine itch.
I had a MK chassis with a ZX9R engine. Loved it. The later E and F model engines had a better gearbox.
I would think that you will get a lot of different chassis combinations, all saying the same.

thanks for the reply i did thnk the which chassis part was going to be a bit broad as i know everyone loves there own cars. so i suppose im just really looking for a decent engine. what are the fireblades engine like
I converted a car chassis to make mine BEC,so no experience of buying a BEC specific chassis!
The MK indy R/RR is a nice tubular chassis,but I would say after recently looking at a MNR chassis they look really well designed and I think that
would be my choice if buying brand new.
Engine wise you would need to go to one of the newer 1000cc engines or a Busa IMO if you want anywhere near the performance of your MX5 turbo 
No real experience with BECs (therefore take with a big pinch of salt), I would go for a Raw Striker with an R1 engine in it (PW model ?) for trackdays. The Striker is arguably the best handling car and is small therefore suits the BEC well. R1 has been done before, donor bike readily available and good power:£ ratio.
i hadnt even considered mnr or striker so will look into those. my westfeild is producing 190 bhp and weights 650 without me in it.
i hadnt considered a busa engine either so another option there. keep the info coming guys this is exactly what i wanted
I have a Dax Rush Tubular Chassis with a ZX12R Engine. Its well balanced and drips like hell. The MAN motorsport Rush might be an option or buy an existing one and refurb it from scratch
Engine is easy. CBR1000RR.. Proven to work. All the bits are available from Andy at AB Performance. between 155 and 165hp at the wheels. you
won't go far wrong.
I have a full CBR kit with billet sump and all the other bits available..
Chassis. Look at what's doing well in RGB. AB Performance Arion is a lovely bit of kit and with a choice between full body and 7 style which is
interchangeable you can have 2 car in 1.
I also happen to have an Arion rolling chassis and body available.
I'd still share the same view even If I didn't have the parts for sale.
Wouldn't it be a much easier and cheaper prospect to swap the engine over in the westy? Am sure a nicely sorted mx5 turbo package would help contribute to a nice 08 on cbr1000r engine which would be my choice if your after a true bec experience. The zx1400 would also be a good choice but doesn't have the screaming revs experience. The 5vy r1 engine is also a top engine (but try and find a goodun)
im bored at home and want to build something else to be honest steve.

if you look up AB Arion S2R you should see the 1 that's been put through IVA.
there are a dozen or so that I know of currently being built for the road. Mine was build for trackdays only.
Fair enough. The AB car looks a good shout. The road going car looks stunning.
And Andy is a pleasure to deal with (unlike Westfield!!)
it would be predominantly track car anyway i wish i hadnt of asked now as youve got me thinking i may like to buy yours lol but im not in the best books with the wife as it is at the moment
If you are widening the search then a ZX12 in a Spire GTR would be another one I would add to the list, this falls into the same sort of category as
the AB Arion but is rear mounted, think of it as a budget Radical.
The other one is the Fisher Fury - basically a slightly modified Striker chassis but with an aero body which significantly helps top speed compared to
a Seven style car. Lost of these about with ZX9, Fireblade and R1 engines and if you are very careful you can get them down to as little at 450kgs
using the lightweight chassis and body.

Striker if you are not too wide in the ass region.
Are you going to the breakfast club tomorrow?
If it's dry dug off here will have his ZX12 powered Indy R there,and I'll be there in mine
I can't make the breakfast meet unfortunately kev
You'll certainly save a lot of money if you bought all Gary's bits and rebuilt that arion.
Nice package that,and should be dam quick!
i have just started a Mk indy r cbr1000rr build, i can't wait for her to be on the road
i have gone for the r chassis with the tubular design and push rod suspension with a full
external roll cage and side bars
with all available carbon add ons bits, as many upgrades as possible
i will uploads pics soon of my progress
I have a ZX9R setup if your looking to go that route, i have lots of spares as in Engines, Heads, Gearbox's.
Also have an Engine cradle for a 7 type car, Propshaft, reverse gear and motor, Shifter kit, clocks the lot. if you wanted to take the lot i would be
willing to do you a good deal on it.
Let me know if its of interest to you.
Thanks
Tony

Hello, sorry to churn up an old thread!
Although not yet being in the position to get a kit car, I'm in the process of looking at BEC's and there's so much engine choice out
there.
I went out in Dug's ZX12 earlier this year and loved it but I see there are Fireblades, R1's, ZX9's and ZX12's out there along
with Hayabusa's which I believe are expensive. Totally unsure on which one to eventually go for. I wouldn't be building it I'd be
buying one that's used.
Are some engines less reliable than others? Are Hayabusa engine's unreliable or is that just on track only?
The car would be a weekend blaster mainly with an occasional once or twice a year trackday thrown in.
[Edited on 18/10/17 by Crazylegs]
If I were building again, I'd go for the Hayabusa engine. Currently have a ZX12R engine fitted and performance wise is equal to the busa.
Unfortunately however, the ZX12R engine was only made for six years 2000 to 2006, so they're getting quite scarce now.
The Hayabusa engines are still plentiful, pretty much bulletproof and great for modifying.
Chassis wise, there are lots of good manufacturers out there, so research wisely and go for the one that you prefer.
Phil
Cheers for the reply Phil.
I didn't realise the ZX12R was only in bikes for a few years. I like the noise off Hyabusas but they're expensive aren't they so I
imagine I would have to pay more money for a BEC with one already installed?
Yeah Busa engines are expensive, old and pretty hard to find decent ones now.
And as you say they do have a premium price tag on any BEC that's Busa powered.
Oil issues are common on them too,so ideally you want a car that's running a dry sump system,so again this adds to the cost of the cars your
looking at as it's £2-3000 for a dry sump system.

Cheers Kev, yes I've read that although powerful the Busa engines can be problematic due to it being a wetsumped engine they can suffer from oil surge I believe?
Blimey, 3k for a dry sump system; that is crazy money. In your opinion, which one is the best to go for or does it not really matter?
I'm reading that either the CBR 900, R1 or ZX12 being the best ones.
a 2011 CBR1000rr was the route I chose but anything after a 2009 will be perfect.
The Busa's are big old heavy lumps compared to a modern superbike
1000cc
Andy Bates at AB Performance has perfected the install and all the parts required are available off the shelf. With power outputs of 165 to 170bhp at
the rear wheels they're not far behind but alot lighter than the Hayabusa, they also come with the added bonus of a slipper clutch as standard

It all depends on what you class as best!
All BEC''s with a everyday average driver on the road will be pretty similar in performance tbh.
The more modern Fireblade engines seem to be the ones to have now,or the big 1400cc kawasaki engines,but you do pay a much higher price as they are much newer.

Is the 'Riot' midi still in production?
That would be my choice, with a Fireblade engine and chain drive.
Yes it is

Not a fan of them you know, they look too short like the back end is missing.
