2.0l 16v Engine differences

So if I was going for a new inlet manifold then it's not a problem??

What about gearbox and engine mounts on ABF is it all drop in like 9a is I believe???

If you're going to run a short runner intake for a turbo set-up then you'll have even less chance of the motor fitting in most cases, because the tightest point is up the front of the engine bay and most of the short runner intakes rake upwards. I bought an EIP one for my new engine and it didn't have a hope in hell of fitting, so I sent it back!

The stock ABF intake actually works quite well with the turbo pipework; it's just a bit difficult to configure the fuel rail and injectors.

Ok well here is the long and short of it, how much better is the ABF if going turbo? I mean I will be heading for hopefully 250-300bhp MAX so is a 9a capable? I know if staying NA then I would go ABF but boost tends to be a leveller......

Or should I got to the hassle of a ABF, again does it fit my stock Mk1 box and mountings like a 9a?

Thanks for the help!!!!!!!

Buy a 20V.

In New Zealand they are hard to come by and I fancy a project not a drop in and run it....... Always preferred idea of 2l 16v in Mk1 anyway........ and have the turbo sorted.......

The 16v turbo is very cheap to do well A couple of grand has it all tied up.

Anyway, yes, the ABF bolts straight into a Mk1 like any other 16v. The bolt for the serpentine tensioner pulley will touch the frame/chassis rail unless you modify it or the chassis itself... Or you can also run a non A/C alternator setup, which sits the alt. lower giving more space for intercooler piping and/or a suitable custom intake manifold. This is about the only problem to overcome, apart from finding a suitable exhaust manifold.

You can run a Mk1 gearbox, but it's not a good idea. Even the stock ABF came with an 02A cable change for strength, so you definately need one with turbo torque

This means custom gearbox mounts, but there are a few places that sell them now - though, they're a bit overpriced

something to think about ..ABF has longer connecting rods....the longer the rod lenght the better the rod ratio at higher rpm and more horse power is developed...just a thought as this is how vw motorsport tuned the ABF...they also changed the jhead angle onto the block and milled it about 7mm off the deck cheers steve
