Any1 Using These Manifolds?

[BLK-51N]

Hey im looking 2 upgrade my exhaust manifold and i came across these on ebay.

http://www.ebay.com.au/itm/RB25DET-RB20DET-Turbo-Exhaust-Manifold-Nissan-Skyline-R32-R33-R34-/251067918897?pt=AU_Car_Parts_Accessories&hash=item3a74d06a31

Im just wondering if any1 has used these or no if there any good, as they are at a pretty good price nd im very tempted 2 buy 1 as a low mount tho.

The positioning of the wastegate pipe scares me. Also, contact the seller to find out the wall thickness... But in answer to your question, no I haven't used this 'exact' one.. The welds look neat enough though.

EDIT: Just realised you said "as a low mount", in which case... As below.

It's well known that china stainless manifolds crack over time.

What set-up do you have?

Unless over 300rwkw on PULP or 340rwkw on E85... Stock manifold is tried and proven to be perfectly fine - so stick with it.

Well im in the middle of doing up my engine atm and my aim is 4 around 280-300rwks on united 100 octane.

Ive currently got

Hypergear ATR43SS2 with .82 rear

Apexi power fc + adjustable boost controller

Nismo 740cc injectors

Z32 afm

FMIC

3" metal induction pipe

Pod filter in plazmaman cold air box

Blitz BOV

Xforce turbo bak zorst

Walbro fuel pump

Splitfire coil packs

I was told that the stock manifold was only good 4 280rwks max. So was gunna just replace manifold when i get my new turbo put on. But if there good 4 around 300rwks i might just keep it nd see how it goes.

I dont think these a china copies either, Says theres aussie made.

You do not need an after market manifold.

The manifold is tried, and proven. Whoever said it was a restriction does not know what they are talking about.

And without even reading the ad, I can tell you it does not state they are locally made.

Why? Because they look like every other China manifold.

im using one but slightly modified. had the external gate pipe re done and boost doesnt spike and has f-all bleed off.. Not a bad piece of equipment after modifying. hasnt cracked or warped yet

also what ash said.. you can make pretty good power using a standard manifold.

+1 stock manifold is fine. no need to change for your power level or the power level your turbo is capable of for that matter.

[BLK-51N]

Thanks 4 the advice guys i think im just gunna stay with the stock manifold now.

I like the bit about the ATR43 and 300rwkw.

Just run stock manifold and External gate it off your turbine housing. You can get 300rwkws from do that.

[hypergear]

You can run an 50mm external gate from the factory exhaust manifold, which results the most significant gain without having to go through the hassle of changing the whole exhaust setup.

The only problem doing it off the manifold, though, is that they are split pulse from factory so if you gate off the manifold you only get 3 runners bleeding off

[hypergear]

You can dill at where the two main collectors meets then mill the divider 20mms in and weld a screamer from there. I saw couple done and worked that way and getting better result then externally gating from the turbine housing.

Yeah it will make 300rwkw
