In search of more HORSEPOWER!

Please, I need some advice. I just recently purchased a 1990 GLI(2L 16valve) and I would like to make some upgrades to the engine so that I can produce more HP. I am currantly having a new transmission with modified gear ratios and an 80% locking differential as well as lightened flywheel and perfomance clutch put in. My next step was going to be a cold air intake or some kind of air induction. The problem is that I can't find anyone who makes cold air intakes for this engine. If anybody can help me with any info on this or any info on any other products that will work for my aplication and add some HP, it would be much appriciate.

Honestly...I wouldn't waste money on a performance clutch on a stock motor. The OEM 16v clutch will hold PLENTY of HP without over heating or slipping (Ive been putting 230hp through mine for a 4 years now). A performance clutch would just be money you could spend elsewhere.

If you have the braided fuel lines, you will not find a cold air intake. All US models came with a form of CIS injection that uses a fuel distributor driven by the intake plate. They dont use the typical mass airflow sensor. Some European models use the Mass Air Flow sensor system tho.

You may look into exhaust systems, cams, minor motor work etc. 2 1/4" cat back exhaust and a high flow cat will make a difference. A drop in panel air filter and modifying your airbox will basically be the same change as a cold air intake. And swapping in Euro cams or performance cams will make a change. If youre willing to go into the motor, you can lighten the crank, or even knife edge it for better flow through the oil. The US 2.0 16vs used a Motronic fuel system (an electric form of CIS) and there are chips available.

Those will get you a little bit more horsepower. But you're looking at internal motor work to gain anything over 20hp.

I have for you a 50mm inlet manifold as used on euro-models of the 16v engine.
I also have the set of cams used in Non-catalyc 16v KR motors.

This is quite easy tuning , as the US models are/were equipped with the rather tame PL cams an dcatalyc converter.
