Turbo Help

[acanibus]

I purchased a KKK K26 Turbo on my 1.8T jetta. I need help. I know I need a mainfold and wastegate. Where can I get one from that will bolt-up. Please help.

I doubt such a thing exists. You'll need to have a manifold custom made. The K26 is a very old turbo design... You are better off getting rid of that and going with something more modern. You are sure it's a k26? Is the turbo in your 1.8t the factory turbo?

Yes, It still has the factory turbo on it. I hate the KKK K03 turbo, plus it doesn't work anymore. Do you know anyone that a call call or e-mail to ask them if it is possible to make a custom manifold for my K26. I know it has a T3 bolt inlet. So do you think it is possible if I were to buy the turbo manifold with the T3 flange on it that it will work?

Yeah... I think the bolt patterns are the same, but I think the t3 ( i may be wrong ) has a square exhaust "duct" whereas the k26 has a round exhaust "duct". You might need to do some porting on either the manifold or turbo or you might really affect the exhaust flow '

Remember... with the k26 you will also need an external wastegate... so you'll need to make sure there are provisions for mounting a wastegate on your manifold. This will complicate your exhaust plumbing.

If that is a good k26, you could sell it for at least $150 bucks... put that towards a T3 Super 60 from EIP... trust me. The k26 won't have the same oil lines or coolant lines as the k03. You will have to fabricate lines for that. If you buy a kit from EIP (or any other company) you'll get everything you need and it will be reliable. By reliable I mean you won't have fluid leakage, don't have to worry about supplying too much oil pressure to the turbo.... etc. Everything will just work. Like a factory solution.

If you start fitting old old parts to your newer car you are going to see problems. The k26 made it's debut on late 70's Porsche's. It's very old and nowhere as efficient as a k03.... Yeah it will push more boost than the k03, but you'll see a drop in gas mileage and significant turbo lag.

If you still REALLY really want to use the k26 I'll do some digging and see if I can find a fabricator for you. I will also look into the difference between t3 and k26 flanges.
