Hey all

Do you guys know of anywhere that sells extractors for our engines? 4g63 that is.

Extractors ?
What do you mean ?

Ok i think there was a bit of cross tasman translation issues there.
I doubt anyone manufactuers manifolds for our cars ( like newer imports ) your best bet would be to go to a reputable exhuast shop and talk to them and try to quage if they know there shit, as designs can vary perfromance widley
In Aus i think beyond the limit motorsport may make manifolds for starions.
What are you upgrading to ?

Sounds reasonable to me.

what'd be the HP gain?

Absolutely no idea, I'm just going for them as my manifold has cracked so I mayaswell upgrade.

Anyone got any clues on hp gain?

did you end up getting this?
how much of a difference did it make?

That image looks like one of the ebay manifolds - they're made in china and some of them are pretty bodgy.. I have a 2JZ one, but suprisingly, when we cut it open, it was actually quite thick walled - apparently some of the others are scarily thin. Even then, there's a few issues for example, I had to get several shorter studs so they don't hit the manifold - also one nut still cannot be fitted on even with the shorter stud as the angle of the pipe is far too close.

Not sure if the ones you're talking about are the same, but there's heaps of people selling them on ebay now at 2-3 times what they cost from china (found the website of the manufacturer), although if you can get one for $200 or so, it's not that much of a risk :)

Yea, My main concern is it wont fit as my car (as probably most of yours)as it's a tight squeeze between the strut wall and engine, dunno if i would get away with it, would it really be worth going to the trouble for the gain?

I have a new stock manifold sitting here as my one is cracked, was thinking it would be safer just to get this machined out to the size of an evo exhuast port and put a TD-05H turbo on.

Yeah, looks like it was designed for a twin cam east-west setup. Not sure if the manifolds are swappable between the DOHC and SOHC variants, but on these setups the turbo hangs, on our setups the turbo is on top of the manifold.

Correct me if Im wrong guys. But Id say its a definate no-go. From the pic above, you are looking at the base, not the top, of the manifold/headers/extractors/whatever.

No, I said "Like this" to give an example, not "These ones" as if they were the actual extractors. I merely put the picture up there to help fil understand without much fuss. Sorry about the bland description :)

On the actual subject I think I may go with just getting my manifold outlet ported.
Does anyone know what you can expect to pay? mrb1?

I would call it a turbo manifold rather than extractors as extractors generally implies non-turbo :)

not if you know what you are talking about. its only the space issues that stup turbos be bolted to the end ofextractors, they would be alot more efficient if that was the case.

those are turbo extractors.

There are 3 types of exhaust setups.
