Hello people. Help is needed here please, if you can that is. And yes, I am serious about this. Having spoken at length with people such as our Nev, other engine tuners and program writers I talked of many different types of engine tunes for my existing VX Turbo and possible transplants. Also spoke at length with Caral Automotive...........YIKES!! Well I am sure that about £20,000.00 + VAT for a kit of parts plus the engine, plus the gearbox, plus ecu etc etc is a bit too much to pay. At my home I have a huge modern workshop fully equipped and in addition to this my good friend is a very gifted Engineer who runs his own business building F1 racing yacht components and is also a total petrol head. My other good friend is a premier ecu program writer. So, I am surrounded by good people and being an Engineer and British Standards Coded welder myself and having done many difficult transplants over a 35 year span I feel very confident with a project for my little VX Turbo. One engine out there that I am drawn to is the Audi V8 RS4 4.2 FSI. Complete with all ancillaries these are being offered to me at about £3500.00 to £4000.00. I like the power output the rev range and other attributes. I am looking at a total budget of around £15,000.00, maybe more, with my labour being for free and not costed. The money that my VX has already cost me has in my mind been written off. So I am looking at a £15,000.00 car. Well, there is not a lot out there for that money which is very different. So here are some questions. Do you think that this engine into the VX is a go situation? Will it require the loss of the boot?...........It looks very wide at the top, unlike that lovely Rover V8 installation which I have been reading about. What gearbox could I use? Would the weight of this engine and a suitable gear box screw the whole car up? Is it a heavy engine compared to the VX Turbo? My VX Turbo handles like a dream now that I have sorted it out And any other points of view. Good or bad, or even if you think that I am crazy. Just one point though. If your points are negative, that is OK, but please give me an alternative view point and why. You could well have a better idea that me. I hope to start the hands on work this late autumn. The reasons for doing it, if I can. Should you be curious. I simply love my VX. I am retierd and need a project. I believe that if it is possible that the end result would be amazing. The sound of a high revving V8 is just the best, in my opinion. Thank you for your time here and any feed back. SO.

Sounds would be amazing, but would imagine it would be a heavy old lump.

Would love to see it done though.

Love your man maths so much:

I love the RS4 V8 engine. Sound glorious and is just about perfect as far as an NA engine goes. You need to speak to DuncanVXR, he knows all about the RS4 v8 and fitting it into a VX. Though maybe with your TVR background an AJP8 and it's flat plane crank would be even better? From what I understand they're much smaller and lighter than the Rover V8 that we've already seen successfully transplanted into the VX.

[GiGo]

Someone has done a V8 transplant, have a search for Something Different, should turn up the result. Good luck with the project.

[techieboy]

P.S. Do you want me to merge your account back into your old Korkey account, now I have the power?

[Korkey]

Hello Techieboy.
Please.....................merge away thank you.

The AJP is a good engine and as you say.............it is very small.
I even built one up with Jaguar heads, 64 valve jobby. What a performance that was.
But getting bits for it is hard. They are quite fragile and I had hoped to leave TVR behind as an .....almost ....fond memory.
However the single plane crank is a real howler at full "chat". Wonderful.

Techiboy. I thought that you might have had weights and measurements at your finger tips for the Audi motor.
You seem to have so much information....hence Techi....well you get it.

So, has Duncan done this or almost or whatever? Do tell.

Thank you.

SO.........Korkey.

Never really been able to find decent measurements and weights for a bare engine, unfortunately. It's probably the only engine that I'd really like to have in the VX. Or maybe the VW R36 V6. They sound glorious as well, when wound up.

So, has Duncan done this or almost or whatever? Do tell.

There was a vicious rumour that he'd helped out on doing a swap into another VX at one point. Though I'm not sure whether that ever happened as I've not seen/heard any mention of it since. But, I think it's certainly his next VX project after he's sorted out Luke's Audi conversion.

[Korkey]

Splendid! I had not even thought about the VW R36 V6..............I will go and have a look. This is why I have posted here. Thank you. SO. Korkey.

[techieboy]

I had not even thought about the VW R36 V6.

You'll need to go forced induction with it, if you're on the hunt for 400bhp+ though.

[MrSimba]

As Matt has already said DG is definatly the man to talk to about anything VAG & VX220!

[Ormes]

save up and get a h1v8 with a sequential box.... mmmmmm

been posted before but what the hell it sounds the dogs...

[Rosssco]

Korkey,

Not sure whether your are looking at a transverse or longditudinal installation, which is the first big question. I'm assuming transverse.

If so, this naturally throws up a number of issues of packaging, primarily related to ancillaries (alternator really), drive shaft position, sump clearance, exhaust routing, boot and engine bulkhead clearance (basically, there isn't enough as far as I can work out - minor mods required!) etc.

Weight wise, the complete RS4 (BNS engine code) is circa 200kg, but removed of ancillaries and non-essential components, weight drops to approx 180kg, which is directly comparable to the standard VXT engine. I don't have completely accurate dimensions of the FSI variants, but the width (as you noted) is pretty big, at ~700mm cam cover - cam cover. Engine height is approximately the same (or slightly less tall than the Z20 engine) and is slightly shorter at ~460mm (crank pulley - bellhousing face). Its actually a very compact engine, just the width, and consequently the packaging of some of the ancillaries that I think may cause the majority of headaches.

I don't know if you've seen this, but should wet your appetite a little:

I also recently spotted this complete engine package for sale

If you haven't already read this, it gives useful information on the engine:

http://www.s4-mtm.co...-StudyGuide.pdf

I've done a couple of desk-top studies on some 6 and 8 cylinder engines that might be go'ers, as I personnally think its the only thing really missing from my VX.

I would also get in contact with Duncanvxr, as he's been up close and personnal with this particular combination, and I believe also has contacts that may be able to help with the engine control side of things, which can get quite complex / expensive due to the FSI fuel injection arrangement. Note that the engine in the above vids has completely done away with this system, and runs traditional port injection, as the FSI is relatively poorly supported by aftermarket engine management it seems.

I still think it is a good option, but definately for someone with the time, space, skills and cash like yourself rather than a plucky spanner wielder like me.!

[techieboy]

Love how he's kept the RS4 exhausts, complete with valves and just re-orientated them in that first video. ETA: Christ, the neighbours and noise police are going to love him, in the second vid.

By the looks of it he probably owns all those blocks and houses surround by fields

[CocoPops]

Ls3? Is that the Chevy engine?

[rob999]

I think so Lee, I thought most LSX engines would be way too big for a VX?

[SteveA]

V8 V8 V8! Nothing to add other than I love it when people push the envelope.

[Korkey]

Thank you all for the feed back so far. This is a great help to me. I knew that some of you would have been here, if only in thought. Ross..............lots of information for me there...........that realy is great information for me, many thanks. I am looking at transverse. I have done lots and lots of Chevrolet works over many years. Great, but old tech and they would need to go in longditudinal and this means longer wheel base etc etc. which I do not want to do Plus I love high revving engines. The H1 V8 is a cracker.............but it is so overpriced. Not because it is so great, but because there are so few. I have been quoted £45K for one....ha h ah a....... Too rich for my wallet. At the moment it is Audi V8 then VW V6. But..............what gearbox? That is the big question now. SO.

[Rosssco]

I'm pretty sure, since the Audi engine doesn't produce excessive torque (~310 lb/ft), that your existing turbo, F23 gearbox would hold up ok. Whether the ratios are ideal for the application, not sure. There's also the M32 gearbox, which is 6-speed, is effectively bolt-in (with a few additional parts). Isn't cheap, but put into perspective with your estimated projects costs / budget overall, might be a a good option.

[Bumblebee]

I'm surprised no ones done a Honda conversion eg civic type r/s2000 or have they? There's some serious big power to get out of these as most of you will know,and there bullet proof,nice and revvy if you like that sort of thing.....I would love to see one of these engines in a Vx
