What these cars should have is a modern interpretation of the Ferrari Dino 120° V6, longditudinally mounted, with the gearbox between the engine and diff.

 

Like the Ford Cosworth 1.5 litre formula 1 engine of the 80's. Absolutely tiny, very low centre of gravity, and very short.

 

 

I had one of those in a mk2 escort.  Small yes but quite wide and destroys gearboxes.  Revs like fook though!  Takes some serious messing to make it drivable as the power band is waaaay up the rev range.  Mine went to the US on a pallet some time ago though.

 

Personally, I find most V6's a bit lack lustre.  They seem to promise so much but dont deliver when it comes down to it.  I'm not sure if its capacity related - small engine (up to 2.5L) is revvy, big engine (over 3.5L) is torquey.  Around 3L seems to have neither.  They do rev and do pull but aren't that good at either.  Perhaps its rotating mass?  Dunno, would need someone more geeky to answer that one.

The 2.7 twin turbo V6 that was in the old RS4 would be ace. 700 odd BHP possible, would be a fcuker to fit though...

The C32B (transversely mounted rear) seem to be the greatest NA engine to fit on a VX to me

 

 

[techieboy]

Yep, would be perfect. Can't be cheap or easy to get hold of one of those though.

[Sukh]

Has anyone ever thought about putting a Subaru/ porsche boxer engine into a vx220?

 

I was thinking Subaru would be easier as it is cheaper to buy, easy mods for power etc. It would also keep the centre of gravity down?

Quite hard to come by for decent money, parts are expensive and the 90 degree V with overhead cams makes 'em wide at the top.

 

Honda J-series engines seem more easy to fit with a 60-degree V, but are more 'load luggers' than high revvers.

 

Small block V8's (like the Rover/Buick 3.5) are easier to fit as they tend to use pushrods so the outside dimensions stay pretty small. Boggo chevy small-block can usually still be bored and stroked to 5+ litres though, so high revving would not be needed..

 

Boxer engines have the problem of finding a compatible transaxle and pretty much always needing to be used in a longitudinal setup as the driveshafts and cylinder heads tend to clash in a transverse setup and they are very wide.

 

Might as well go really off the wall and stick a Renesis rotary in the back if you're going to do that anyway

 

Inline engines (3/4/5 cyl) will always be easiest to transplant in a VX chassis though if you don't want to start modding too much.

 

Bye, Arno.

Would love there to be a ready-made conversion out there (previous car to the tubby was a 3.2VR6 S1 elise  ) - there was a chap up north doing a toyota V6 conversion on an S2 last year or year before as the idea of having it as a turnkey conversion. Can't remember the name now, Woodsport maybe?  Well-known on MR2's.

 

If it went well in the S2 then it'd surely work well in a VX you think?

I remember reading about it on Seloc but it all went a bit quiet....

Unless it develops a minor leak during and impact and you end up upsides down Minor niggle...

I remember this from my MR2 days, it was the engine from the 3.0 Camry.  If memory serves you had to give your car and a donor car to woodsport and they would do the rest. There were supercharger kits available from across the pond as well. 

 

A supercharged V6 VX220 would be quite a thing!

[Rosssco]

Yeah, there was a Woodsport 1MZ-FE (all alloy Camry engine) put in a S1. Problem was, the S1 Elise has a smaller engine bay and more restrictive rear subframe than a VX or Toyota engines Lotus. This meant major subframe choppage to get the rear cylinder bank to fit. It would fit in the VX engine bay, but then, you'd really need to want the V6 sound, as that engine wasn't really any more powerful than a basic Stage 1 SC. The very rare SC for that V6 is very expensive, and a weedy M45 unit that can't be chargecooled. Of course there was the GM V6s that connect to our gearboxes,, but they seem to be fairly much unloved in NA form, difficult to tune, even though I think some of them (3.0 and 3.2L) versions might be interesting if you got one cheap, wanted a project, and had the skills to fiddle with the thing.

That's right, I remember now.  I considered having the conversion done but the power (or lack of) put me of.  My MR2 tubby in basic form had more power than a converted V6.  I vaguely remember researching the supercharger and finding the price difficult to live with.

 

Like you say, a V6 powered VX220 would sound lovely but the conversion would be a right ball ache.  Good luck to any one that tries.

Here is a swedish guy with a BMW V10 in a Exige, seems to fit with some surgery...

they have to be two of the very worst conversions I have ever seen done to an Elise!

 

the former is a cast iron ship-anchor of an engine with no gutts, the latter a huge gutless wonder.

 

I'm no fan of the 2ZZ, but the fact it's head and shoulders ahead of both kind of makes the point.

Hi, Does it happen something here you might wonder? Oh yes, but I'm a little disposed to update. Buren, rear frame, engine beam and little else has come back from powder coating. After they came back and I put everything in place so the "Gäddhultarn" been here and welded the parts together that belong certburen. It will be a deomonterbar part on each page that contains door endeavor and "toyota stag", this is to only use the bank / race driving when it becomes unnecessarily crowded to get into the car with it installed. I even finished building sump with dipstick; welded a bit in front of where I rebuilt to get the engine further forward in the chassis and welded there wart for oil temp. before the trough was mounted back I built on Vanospumpen, removed plunchar and bearing part of pumperiet and turned a sleeve of not getting internal oil leakage. Unfortunately, you can not just remove the pump as it also ensures that the standard oil pump may drive. Next step will be to build on my new Vanos blockages that I received from Daniel Andreasson on Tjorn, more on this later. / Z

That V10 is a masterpiece of an engine! Anything with that in it becomes awesome, even a 5 series

Well as it was my car at one point I guess I could add some comment. Worst conversion? I wouldn't completely agree but I can see where you're coming from. It needed yet more work from an engineering aspect and was bodged in some areas. Having said that the fact it worked at all, didn't have any chassis cutting going on like the woodsport one and at one point was scaring GT3's around Brands Hatch was what turned my head. All that pig iron weight was up against the bulkhead by the way, much more forward than the k-series or any Honda/Audi conversion. It was a significant weight though... If you had it in mind that it turned the lightweight elise into a sort of TVR Griffith-type elise then that's about right. In the driving experience at least. When it worked and you had the opportunity to floor it the sound was delicious and it'd rip up the road at a helluva rate. The problem for me was that it didn't have the reliability of a Griffith (and that's saying something) and quickly turned into a money pit. In my younger days I'd have had the patience, though maybe not the funds, to get it working reliably. Now though I'm old and just want stuff to work. At least for half the time!! Had so many plans for that car but reality is a pisser sometimes eh?

[Rosssco]

What sort of issues were you getting Moospeed? I did really like that car, especially after hearing it on youpube.. The VR6 would have been a really good 6-cyl swap engine, if they only made an all alloy version... The Woodsport version was also good IMO, but just too much choppage at the end of the day, to end up with 200bhp... You'd have to really want a V6 sound track more than anything else.. I did enquire to MWR a bit back to see if they planned selling a 2GR-FE conversion kit for S2s (hoping it might work out for the VX), but they had no immediate plans to.

Is it really? 5 litre not more then 500bhp not that impressive

and I Heard it´s very Heavy!

 

What are we looking for with the V6?`the sound? much bhp without turbo and with a small light Engine? Smaller then  big block V8?

 

What about a stroked Honda K24 with 2.6(2.7) litre performance cams 8300 revs E85 fuel and 340-350 bhp without turbo.

Thats probably unbeatable price, weight NA Engine with a lot of BHP.

[Claws]

Yeah, it tunes well, the stock exhaust alone is very restrictive. Not to mention that 500bhp is 500bhp, in NA form ...that sound
