Official Turbo Header Thread..

i might know a guy in florida......

I hear the wait is suck, though. Good work keeps the waiting list loooong

[RedZMonte]

yeah, im gunna do a compression test here soon (been fixing other stupid shyt) and as long as the compression is good i need to do HG's. the rear head is leaking a litle and the front is leaking oil down the front of the block all over everything. When the heads are off im gunna have them freshend up a little, new seals and maybe springs/retianers. dont think im gunna do a port job or anything.

While you have the heads off and apart, you may as well at least polish them up a little inside. Even if you dont remove alot of material Im sure it will still help out. You wouldnt want to put it all back together and then decide you wish you would have done it.

maybe, ive decided if my heads are not flowing enough i just need to cram more boost threw them . lol jk... Ported heads on a turbo car make much less of a differnece then NA or SC. if its cheap i might do a light port and pollish but most likely they will get freshened up and new springs/retianers and thats it.

WHAT? Since the percentage of gains for a port job will be similar from NA to boost, you will gain even MORE on a set of PROPERLY ported heads with a boosted car vs N/A (end HP)

[robertisaar]

^ what he said, LOL...

since the heads will physically flow more, let's say 8PSI at 5000RPM on unported heads is 300 grams per second. now, if you improved flow enough, that same 8PSI? it's actually more flow since there is less restriction.

or at least that's my take on it

Eventually the valves will become the next bottle neck.

Eventually the valves will become the next bottle neck.

Eventually everything becomes the next bottleneck. Estimate for valves to be bottle neck? Right after you break the block.

Splitting the block is the goal!

Kicking ass and chewing Bubble gum is the goal....... Running low on gum

but for real... Im sure the head porting will help but in not looking set a record.... Just enought to not smoke and make enough power to have just about anyone go WTF?! Was that a 2 Door lumina pulling me?!

[RedZMonte]

BTW the manifolds are at my new welders shop and should be done soon.... Looks like im doing head gaskets just as soon, then will get the new X-over made and maybe a new DP... they dyno tune... gunna be a expensive few months

[pocket-rocket]

New welder? What happened to the last guy? At least if you are doing head gaskets you can take care of those valve stem seals now. If you go with the Felpro head gasket set, it comes with Viton stem seals.

[RedZMonte]

That is the plan when the heads are off. The old welder is still around just busy and this is a small side project and low priority so i got another guy who has a little more time for my stuff. he does great work so im excited to see them when done..

[pocket-rocket]

That's cool that he hooked you up with someone who can do it. People like that get referrals from me because of the way they handle business/people.

[grandprixgtp_93]

they look great man youll have to get picks up when your done im interested in seeing how you mount a turbo with the dohc engine as im about todo the same thing on my 93 gtp
