Has anyone attempted or put serious thought into this engine approach? I realise from a purely performance per pound perspective, its not quite as competive as the traditional turbo / SC 2.2 route, but it ticks a few boxes from me... I would think mechanically, it would fit relatively simply (bolts to the F23?) and it doesn't seem to be a excessively complex engine with dual VVT or such like. packaging wise, I would think engine height and width would be tight certainly, but nothing too bad here. A lightly tweaked version will give 230-240bhp (210bhp standard) and similar torque figures (with tons from tickover) , will be equally reliable, sound great etc. I would estimate weight to be somewhere between the Z22SE and the Z20LET (~160kg for a modern all-alloy V6) so can't see excessive weight being a problem. Thoughts on the matter? Ross

3.2 V6 engine weighs quite a bit more than a z22se, but probably similar to a turbo lump I'm sure it could work and perhaps one day someone will fit one

It sounds like a good idea to me. A high torque figure from 1000 revs would be nice. I wonder if a supercharger kit exists for it ?!

[Seb.F]

Would be quite a project for someone mad enough to take it on. The problem being there are far too many 'easy' options to get more torques, so can imagine noone would bother.

Gotta be easier than a Rover V8 conversion, and thats been done

I wonder if a gas turbine/electric hybrid would be a better solution - along the lines of the Jaguar C-X75 Concept. A much more compact powerplant and with plenty potential for setting up active torque vectoring if using one electric motor per wheel. Seriously though, the V6 sounds like fun for someone who enjoys a challenge. Each to their own. Good luck if you decide to go for it!! Paul

2 problems with turbines. Firstly the exhaust gases are extremely hot and come out extremely fast, dangerous to passers by! Secondly the noise is mental!

Thats why they should be restricted to pushbikes That was the plan this summer if i had it spare

Engines around that capacity tend to be lazy. They dont have the revvy nature of a smaller 4 pot yet dont have the torque of a big V8. With a light VX a fast, responive engine is usually prefered. It can come down to preference and driving style. I had a 3.1 V6 once upon a time and I found that nice to drive. ETA: Personally I'm waiting for someone to fit a 4 rotor mazda rotary engine.

I'm working with a guy who has an Audi R32 v6 in his Elise s1 He's promised me a spin in it next weekend.

THIS ^^^ would be mental! noise would be immense (along with the fuel consumption)

Yes, no doubt it wouldn't be comparable to alloy 4-pot, but quite a few alloy V6's seem to compare favorably with iron-block 4-cylinder turbo unit from what I've seen.

Absolutely agree with respect to easy torque, and I've already bought a few bits for a Stage 1 SC just in case Its about power / torque delivery as well though, for which for I prefer NA or SC. It all really depends how easy it would fit ...

Everyone likes a wankel! Me included...

Re: V6's, I think it depends on the engine, specific application and state of tune, granted in standard form with a DMF and stuck in a Vectra, its probably no motorbike engine. A decent sized V6 with lightweight flywheel and not much weight to move will rev pretty freely. The VQ35 in my old 350Z reeved pretty well, and that had a chunk of a car to move.

Oh and don't get me started on V8's...

Matt black JSD car?

Might also be worth mentioning woodsport, v6 converters of MR2s. They have a build blog going right now on seloc. Can't see why that wouldn't fit - in fact, more likely to compared with an Elise no?

Woodsport are getting on with their Toyota V6 into Elise swappage...

Yeah I've got 2 MR2's, and bought 2x Toyota V6's in the past, but never fitted them. I've a ~350hp Toyota 3S-GTE engine / gearbox package I'm going to sell, maybe I should look to 'lob' that in and forget about all this V6 malarky!

You want one of these:


Mega power, mega revvy BUT mega expensive to make road drivable and mega expensive to rebuild.

[slindborg]

This even has its own subframe, so its literally 8 bolts......_{and a fcuk load of bodywork} to get 700bhp and mega torque in there

[FLD]

Mine was straight forward in a mk2 'scort. 2 bolts on the engine mounts and the gearbox mount and haul the beast out. Had a T56 attatched which weighs a ton!

pretty much a jet engine then and the 4pot was simply there to start it
