2.0gti turbo conversion?

You do realise that running your car on bike carbs is a no no as it won't pass an MOT as the mixture won't be right enough to run a cat, don't you?

Anything past 1992 needs to run a cat.  You can't run a cat with carbs.

Emissions tests are easily cheated.

Wrong

Mine has past the last 3 MOT with the S3 engine, and NO cat
My car is a August 1993

I genuinely didn't know that, but how did it work on that cobra kit car project on wheeler dealers where they put cats on a holley carb'd chevy motor?

Was that not for SVA (Wheeler Dealers)? That has slightly different rules on emmisions etc.

I think there are older examples of cars (and possibly motorcycles) which used carbs and had a cat but I suspect this is of a different type to that fitted to modern cars. Not running the right AFR will kill a cat so that will be why those horrible SPI systems appeared in the early 90's.

Are those carbs designed to be pressurised? Doubt it. Gonna be alot of headaches with that carb setup, expect it to leak fuel and not run very well. You should be using some form of programable ecu so you can control the engine properly.

Would like to see how this will run although have doubts that it will run well without proper controls.

Well all the grass track boys and pit racers round here are putting carbs on cars with no problems, including mk3 golfs, so i don't have any worries about that bit.

My neighbour is a bike nut and owns his own business selling and building bikes, and he has supercharged a zzr1100 so I'd say they can handle a turbo, he was explaining about the zzr1100 being a ram air system and them being ideal carbs to turbo, only carbs he would suggest over zzr1100 carbs are cbr900 carbs.

like i say, I'll see what happens when i get round to finishing it, just fancied trying something different, I asked all the questions I could, got as much information about it from everyone as I could, then got to the point where I had asked all I could, found that in theory it should work, so  just had to start building it to find out, that's why I bought a second engine, so if it doesn't work or goes bang I can put my one back in.

Ram air only becomes effective and high speeds

[tshirt2k]

Ram air isn't the same as turbo air flow or boost either.

Looking at less than 0.5 psi at 150mph.

Switching to carbs is a bonkers idea, fuel injection is a lot better in the long run.
