Spot on Brett
Was so very tempted to modify the front cross member but even then there was no chance of a V10 and I did think it was a step too far. With an eye to the future it wouldn't be too difficult to reverse my mods.
Two litre (with options 2.5 or stroker) flat four and what must be one of the best ratio's of £££ to HP. Drive shaft angles are spot on, rear of the gearbox is within the bumper line, so far it has worked out extremely well. I'd love to be able to free up some time and push on.

 

[Brett]

Haha. I spent sooooOOooo many long nights working out measurements and taking dimentions of different engines I'm 95% sure there isn't any other setup that will allow a good driveshaft angles. There is so much bang for buck with the modern turbocharged engines that it makes perfect sense to do an engine conversion if your balls are big enough. You will have a fabulous COG and much better weight distribution. Is it a 5 speed fwd box you are using or a converted awd?

 

[ed_harland]

It's the 5 speed AWD with the centre diff and rear drive extn removed. Manufactured a dual splined adapter that locks the centre diff input to the front drive output which effectively turns it into a 5 speed transaxle. Three types of diff available and a few final drive ratio's. Numerous aftermarket gear trains available, straight cut as well. If you want to pay the money some will transmit up to 700 hp and huge torque. Just like a PK6 !!! :rofl:

Well done that man. Not sure i like the idea of a 4 cylinder engine in a vee but can totally see the benefits of this set up.

What type of lift do you have ed?

 

[ed_harland]

I guess technically it's no longer a vee, I love the vee and wouldn't be going down this road if I didn't have a one owner example parked next to it !
I just fancy trying to build something seriously quick and different just to show I still can. I have kept in mind that one day it could be returned to it's original spec.
The lift I bought for my business back in 1974 !!! It's still going strong ! Although it is designed to roll under a vehicle I have only ever used it in a fixed position. It lifts horizontally about four feet, ideal for servicing brakes etc. and can tilt in either direction so you can stand upright under either axle. Very good if you have limited headroom in the workshop. No memory of the make, I know it's no longer available.

My tuner has an 800hp F4R - Turbo lump in a Renault 5, I was looking at it thinking "That would fit in the back of the V6..."

 

[ed_harland]

Go for it Dave, it would be a relatively easy conversion.
I wanted to get away from the transverse layout but like Brett says above anything more than 2 cylinders in line means cutting out the front crossmember. I did look closely at trying to fit a 4 cylinder Renault and transaxle to get the full 'Turbo 2' layout. I have no experience with building the F4R other than cylinder head work and servicing plus I know I can source plentiful Subaru parts for very reasonable money. I'm running on a very tight budget and I'm making sure that I can recover all of my expenditure at anytime.
I think there was a guy who did a very tidy conversion with a transverse Toyota? engine. I sort of like the challenge of something totally different.
The flat four ticks all my boxes !

Something wrong here ?![album]17594[/album]

Where is the engine?!

Seriously Ed, if that is it then the CoG should be way down - absolutely superb. :approve:

What is the difference in weight like between the flat-four and the V6?

 

[ed_harland]

Thanks Dulan
Will be a big difference in weight although I haven't weighed the individual units. You'll remember that I weighed the car before so will be excited to see where we are once it's back together.

Would also only last 5 minutes on a circuit lol Although detuned to around 400 or so it'll probably be happy as a jay bird.

I looked at all avenues in fitting a transaxle. You can fit a UN1 gearbox from the Alpine line up relatively easy. The Venturi 300 Atlantique uses an L7X engine and said gearbox and the bellhousing is available. The un1 isn't with out its faults though.

The crossmember in the engine bay is the only thing that provents you from gaining the 15-25mm needed to fit a v6 in that fasion and maintain decent driveshaft angles. The only v6 I haven't measured is the 2.0 mazda v6 which may or may not be shorter.
Audi are now producing transaxles where the driveshafts are forward of the bellhousing which may allow fitment of a v6.

Very tasty, reduction of weight and lowering all in one should be a real plus, why not go the whole hog and hitch up the front end?? :bow:

 

[ed_harland]

About an hours work to get the Momo gear knob off !
May be worth it though ?[album]17794[/album]

 

[Kett]

Innuendo city!

What's it to be...
Carbon fibre?
Balsa wood?

 

[ed_harland]

This Momo one was horrible, larger than the OEM (and heavier). I have to do away with the 'lift for reverse' so it had to come off.
Not sure what I shall replace it with, it needs a certain weight for the right feel, maybe i'll make one.
I like the OEM but it would have the wrong shift pattern marked on it.

[DaveL485]

A mate offered me this for mine the other day, as it turns out its a Laguna six speed knob not a Vee one - so its available if you're interested. In Renault packaging with part number.
