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

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.

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

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.

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
