Choosing an engine.. a nutty thought on a friday
tegwin - 19/12/08 at 02:28 PM
Ok ok.. so I have this weird idea that I want to get an older style polo... fit an MX5 rear subframe and diff... fit wider wheel arches and stick a
more interesting engine in the front....
Here is where I am stuck... I want to be able to use the car to hammer around alpine roads...enjoy all the fun that our country roads can offer at 4
in the morning....
So what engine should I fit? (It HAS to be VAG!)
I could use the popular 4 piston 20V turbo engine... That is good for 350-400hp with out a silly amount of work.
Or there is the V6 engine from the VR6...
Or the V8 from the passat/audi estates...
So which engine would you choose and why? And what gearbox would you use?
(I know some of you might think this chavvy... but its interesting and I like it LOL)

absolutely no idea when it comes to VW engines, but love the car compared to the original. I dont think making something look more aggressive
instantly makes it chavvy, although the car in the picture could probably be toned down a little!

i would go for the turbo engine simply because i think cars with turbos are more fun!
quite a few 1.8t's knocking about aswell..
cant wait to see this if it materialises!

How about using a V6 4motion golf or passat? if your cutting the floor anyway then why not 4WD!
Plus you can use one donnor car for everything keeping it locostbuilders style!
I thought about this for my MK1 golf but its too solid to hack so 20V turbo for me
Miks15 - 19/12/08 at 02:52 PM
Im with Jimbob, 4WD would be great fun in a car like that, I reckon either that or go mid-engined

Oh right.
Well, as you didnt state a budget for the car, my vote goes for Veyron engine

I like the car in the picture!
VW only you say, so it has to be a W12 engine with a couple of turbo's
tegwin - 19/12/08 at 03:14 PM
Haha... mid mounted W12 engine... as per their concept golf...
The heat from that would be painfull..
I fear the w12 engine would be too heavy...
Turbo lump would be nice...
How hard would it be to transfer a 4wd system into a smaller car... it would add a lot of weight and compication... not sure the handling would eb any
better than a rear wheel drive car...?
cd.thomson - 19/12/08 at 03:16 PM
you wouldnt see the same handling increases, but it would help get the power down onto the floor enormously. Even considering the extra weight of a
4x4 system you would be seeing improved performance over a rwd car with the same spec.

The only issue I can see is gearbox choice if you're planning front engine/rear drive with a VAG motor. I know there are Ford gearbox adapters
available, but if you're going to use an MX5 rear end, why not use the engine and gearbox too with a shortened prop?
martyn_16v - 19/12/08 at 04:55 PM
You could always get the transmission from a 924, it's about the closest thing to a VW RWD. I'm not 100% sure if the bellhousing pattern is
the same as the 1.8T though.
I've had similar thoughts for a while now, but a mk2 Golf RWD with an Audi V8
tegwin - 19/12/08 at 06:21 PM
Hmmm...
The porsche uses a transaxle at the back...
hillbillyracer - 19/12/08 at 07:31 PM
How about using the gearbox from a Quattro model of some sort but lock the centre diff & not bother with the front shafts to make a RWD box that
will bolt straight onto your engine? Mabye more work than converting the bellhousing from another RWD box but worth a look.
Mabye look at some diesel Volvos? They used the VAG 5 cylinder diesel for a while so mabye there's a box with the right bolt pattern there?
If you were going 4WD it'd have to be the transverse set-up from a Golf etc, the in-line layout from the quattros puts the engine right out ahead
of the front axle line. 4WD sounds like a lot of weight & compliction that could spoil a nice idea though.
PPC mag did a featrue a few months back on a mk1 Polo that had a front mounted bike engine & RWD.

Depends whaere u want the power.
YOu could get a v6 syncro passat for not alot of money and use the hole drivetrain with a shortened prop. That would give you low down power. Theres
supercharger kits for these for an extra kick up the bum.
Failing that a 1.8t.
Audi quattro 5 pot turbo? I saw a vid of a mk2 golf with this in. 550hp or something just trying to find it,.
repper - 19/12/08 at 08:14 PM
chop shop put a scooby in to a golf why no do it to a polo
4x4 turbo
Danozeman - 19/12/08 at 08:36 PM
Here you go 550hp golf

What's wrong with that? Torque tube shouldn't be too hard to shorten if needs be, and it'll put a bit of weight over the back wheels,
which'll probably come in handy
