Autobahn88 or GTpumps mani

[LumpyVR4]

When I first got my VR4 I was all excited and without doing any reasearch just jumped in all nube like, and bought an autobahn88 evo III stainless manifold . In hind sight not the best move. I hate wasting money, and find myself flip flopping between planning on getting the autobahn88 one ceramic coated and fitting it, or assuming it will crack and instead planning on buying a GTpumps/JAWarehouse evo III manifold and getting that coated. At the moment I'm not sure exactly what I have. At best I have a stock evo II manifold (car has an EVO II turbo) or at worst the stock VR4 one. Which way would you go?

 

[DOUGMO]

if you have a stock 2 manifold I would give that a port and get it coated

I agree with the above.

OK, I've googled and not found too much info on the evo II manifold. Is there an easy way to tell?

It is possible to port anything, I'd be more inclined to either buy an evo 3 mani and port it, or port your own. You can pick up an evo 3 mani cheap enough.Those pretty ones are crap, I'd be worried some of the crappy welding will fly

off and frag the turbo.

I wonder what the quality of that is like but ^

Gt pumps cast mani matched to there 20g and be done with it

Aren't GTpumps, jawarehouse and the one above all the same thing. They all have the same casting marks/lettering. Or is it a case of Chinese knock off where they copy it exactly?

 

[croket]

Dunno but i know gt pumps and there 20g turbo works well together with my engine , full boost by 3500 and holds all the way to 8500. 5000rpm worth of boost is great !!!!

It gets a bit of creep even with the 34mm internall gate

I have heard similar things..so quite possibly true.

I like GTpumps manifolds. I have good experiences with them in the past.
I wouldn't bother coating your SS one man. Cracking can also be caused by badly hung /damped exhaust systems.

On a side note, I just bought another VR4 today and it has a coated tubular manifold (looks to be mild steel) and it has a brand tag welded on it's no.1 runner. It's faced right down so I couldn't read it easily but myself and a mate deduced that it read "M&H". Does anyone know anything about these manifolds?
The car had a cheap ebay intercooler kit, chinese turbo, nyloc nuts holding the exhaust manifold on and other cheapy things riddled through it so it seems the previous owner is into cheap stuff. Just wondering if the manifold is any good without having to pull it apart and inspect it.
Also, do all tubular header get red hot very easily? I just drove it (yes I was smashing it) about 1km and the thing was glowing soft red.

Wow, sorry to hijack thread man, didn't expect to type so much haha

This the one you have by anychance?

Im no expert but im not sure if the header should turn red easy, ive seen videos on dynos with then having a red glow but never normal driving, but in saying that i had a brand new hi flow cat from liverpool exhaust put on my old gsr and after a mad run i noticed the cat was glowing red hot

Found something - http://www.mandh.co.nz/1new.php

It's 304. That explains why it's rusting.

 

[MDK87]

Haha we found it at the same time! Thanks man.

And yeah, I know after hard driving they go red, but I only went around the corner (~ 700m) filled up petrol, and then wound 2nd gear out on the way home. Lol

I'll probably swap it for a GTpumps one.
The last guy sold it with overheating issues.
I found the stock fan shroud near the manifold had melted severely, inhibiting movement of the fan blades. Chopped out the melted section, got the fan working and she runs mint.
But yeah, goes to show they don't hold heat very well. This one has that high temp coating stuff too.

Anyway, enough hijacking for now. Lol
