M20 Turbo Manifold Question

[SkiFree]

Haha, first post on this board and I'm already in trouble...

But fair enough. Looks like a good text. I'll have to go through it.

I have done an incredible amount of reading in the last 4 months, and will continue. I am much further ahead than I was prior to.

And I am not too worried about cost. $6k in my eyes is worth it to spend up front on a reliable machine.

Sounds like you'll be just fine then. Forgive us, most of us are used to dealing with the lowest common denominator.

Than you should be ok. You see to many times people popping on here asking how to turbo and that they have a $1500 budget.

instead of asking a bunch of questions spend some time reading
i read a book that was really helpful with learning all kinds of stuff about going turbo
it was called Maximum boost

Hey Guys,

Sorry to be such a noob, but I am looking into my first turbo build ever (from know almost next to nothing..) and am currently trying to pull together a parts list. Really want to go with the good quality of everything I can get. The jg technik manifold I have seen looks like its pretty well done, and have messages them, however their website seems to be no longer up?

Also, curious as to what I am looking at in the pic. Does this manifold have two wastegate provisions? If so, what would be the benefit to that?

And not to scare you off but if you say you want to go with good parts...depending on your hp goals I'd safely recommend you pigeonhole a good $6k. Boosting a car goes well beyond part you slap on the motor. you need to think about everything behind the motor, what will run the motor and tuning. Don't let ebay numbers fool you, proper turbo setup is not cheap.

Twin scroll. Divided manifold = 2 wastegates.

Why do you need a on center turbine housing? with the tcd manifold.

Probably because of clearance to the head, on center would move the center axis of the turbo closer to the fender

[jules325i]

That cxr or whatever it is is ultra crap.

This is probably what you're looking for.
A revshift adapter is going to be the best though.

tcd you need an on center turbine housing.

ok ok :D

but in reality... is some diference there or not
I just don't want to buy overpriced manifold :D

It's the same thing.

Both seems to be crap :tsk:

Split pulse and fairly decent size ports. Remember the m21 boost 13psi stock. Many people boost 18psi on them in europe. There are quite a few m20 people making over 400whp on these manifolds with a Holset mated to them.

Yup. 1bar and 350whp seems to be common with the hx35 and td manifold.

hey, is there some real difference in manifolds between those two sellers, or its the same product only price is different? :D
