16 valve conversion with a Stealth racing turbo conversion...will that suit Sir?

Would have thought buying a 16v and converting would work out cheaper

mmmmm turbo yes please! but think maybe a little out of my budget unfortunately! do they do a k-jet 16v? if so would i be able to just use the basic engine and the injectors and other parts from my 8v? or would a digifant 16v be better for tuning? (first vw so dont know too much about them so please be patient!)

All the mk2 1.8 16v are k-jet, but while the blocks are similar, the heads, injection system, and ignition systems are quite different.

The injectors on the 8v are in the head, whereas the 16v they're in the inlet manifold, so you can swap it for throttle bodies or carbs, whichever your preference.

The 16v is a much easier engine to tweak

The pistons differ on 8 and 16V blocks.

Sell it and buy a good Mk2 16v. Converting your current vehicle will end up with a botch, no matter what you do. Buying one that started life as a 16v means it is all as VW intended.

However, if you are not going to an 1800 16v, you have a decent starting point for bigger engine conversions. The VR6 or 2.0 16v are both popular conversions. Or a G60, although these are a little old-hat nowadays. Or spend a bit more and get a 20v turbo - and that will really fly.

Get over to www.clubgti.com for lots more advice.

No matter what you do its going to cost you a fair bit, 8V wise your looking at cam, head & injection modifications just to get half decent power. 16V, good cams will make a decent gain, carbs can gain even more power but inlet manifold length will dictate power & torque characteristics. Go for VR6 power, its bombproof, reliable all day long & you can tune the nuts off it for the same money you would spend on a 16V motor!

DeltaFox, fabulous looking motor, but why (and I'm going to be really cheeky here) didn't you clean up the inlet manifold?

Darran (hoping he hasn't offended and that he's not made a complete idiot of himself mis-identifying the rusty looking part at the back of the head )

Its the exhaust manifold, and its made of cast iron and they generally do rust!

delta that looks sweet! would like a mk1 but enjoyin me mk2 at the min and got me eye on a vr6 conversion now! what kind of performance does a standard 2.8 have in a mk2? is there any problems i should look out for? what are sensible, fairly cheap mods i can do with a vr6? (a turbo or 2 or a supercharger would be nice but not exactly cheap!) (would be fun though! )

Lol yeah its the exhaust manifold.
They tend to rust anyway at first until theyve been heated up and after that they seem to be a bit more stable as regards surface oxidation.
I have since coated it with a black ceramic paint compound so its not rusty now, although, you cant see it down the back there anyway!

I knew in making a smart arse comment like that I was bound to make myself look an idiot by identifying the part incorrectly.

Glad no offence was taken though. Should look nice in black.

the VR6 is SOHC, the R32 is the 24v DOHC engine.

I thought the VR6 came in both 12 and 24 valve guise.
