Title: 20v Turbo conversion.
Post by: andybond on 22:56, Tue 06 July 2010
Anyone any experience of doing this ? I am aware there is at least one car out there with this.

Would love to hear from someone who has done / plans to do this imminently ..

Duncan Greir on RTOC owned the Car
Scoff on RTOC did a lot of the custom engineering

You basically need a modified subframe & engine mounts & then all of the relevent 20V Turbo bits.

I've a MK1 Williams with the 20V conversion in. I didn't do the work, a guy called Flan on WilliamsClio did it.

My car runs 246 BHP & is proper quick!  :lol:

Here's a load of pictures of my Clio.

Audi, Seat, skoda  it's the 1.8 20v turbo engine they use, Im belive some engines are slightly better spec than others within and some come with different turbo's

As Steve says above Scoff done the R5 conversion now ownerd by Minty on RTOC.  And Steve has a super sexy 16v clio with the conversion aswell

Scoff didn't own it Scoff built the R5 20v turbo engine the owner at the time was Duncan Grier

Done a few of these in my time - very simple to do, cheap and effective.


I Built this back in 2003 - you may know it as the Clio TT ? its been through a few hands since i sold it.

I think some guy of RTOC owns it now and the last i heard he was butchering it to drop in a 5 ?  :cry:

I though i recognised your name, your also a cliosport member aswell.

Yeah the car is now owned by Paul aka Minty83 on RTOC but I believe it is still in one piece and I think from his sales add on RTOC that the car has this week been sold on again and the owner is an unknown.

For the masses.........

First you will need an AGU lump ( big port head ) found in the 150 bhp audi A3 / Golf gti. Try and get a complete lump from a donor car with the gearbox and shafts etc. The standard crank is good for 450 bhp. I took the bore to 82.5mm ( 1900cc ) and ran JE pistons and IE Rods.

At the time i bought a turbo / manifold and injector kit from Jabba sport but you can pick one up a hell of a lot cheaper than the "at the time 2000" kit ( bearing in mind this was back in 2003 and this was a new thing at the time ) the turbo i used was a IHI VF34 with bosch 440 injectors and a pace intercooler.

I ran a DTA eng man system + loom. A decent fabricator could build you a manifold / down pipe quite easily. The flanges are available from pipe werx ( ian birch ). You will have to fabricate 3 engine mounts ( use the 1.8T units ) o/s/f + n/s/f and a rear dog leg mount.

I used the VAG inner CV and shaft to mate up to the VAG gearbox end, chopped it 3/4 way down and then chopped the renault shaft and inserted it into the hollow VAG shaft, measured it with the renault side of the shaft in the renault hub. Once you get the length right ( make sure car is on the ground with engine and box in ) mark it up, tack it with a mig and then remove it. I drilled straight the both shafts and pinned them + welded the join. The car was just over 400 bhp and the shafts never snapped once.

You can run either a DTA or Emerald set up to supply power to the lump. I also uprated the fuel pump ( walbro unit from an evo )

The VAG gearbox runs an hydraulic clutch with a master and slave cylinder. I cut the master cylinder off a Golf GT TDi clutch pedal and welded it up to the Clio pedal. I than fabricated my own clutch pipe ( used a motor bike reservoir ) and then mated this up to the standard VAG slave cylinder - bleed it up and away you go.

The standard Audi TT clutch handled the power fine. Use the petrol 5 speed box - i made the mistake of fitting a 6 speed Golf GT TDi box with a quaiife LSD which limited my quarter mile time - a 5 speed ( 02J ) would have powered me into the mid 11's no messing.

This gives you a quick insight as to what to do. Theres not much more to it ( i make it sound easy lol ) if you need any help just pm me or email me at renaultengines@hotmail.com

These engines can be taken up to stupid HP ( my pal runs a 750bhp MK1 scirocco that runs 9's ) if youv'e got the coin the sky is your limit.

I may have some pic's (might take me some time to find) as when I done my conversion rwd 5 vag I done what scoff original done on his vag conversion which basically cut the shafts to length and then lath the gtt shaft down to slide in the VAG shafts, oh yeah and castle joined them welding together
