I actually ordered my JM to have 1&1/2 inches removed from the manifold runners to suit the cordia.

When it arrived the manifold didn't fit due to clearance issues.

The runners were all cut and 90 degree angles installed. This allowed the manifold to clear the heater hoses and the brake booster.

The welding is as or not better than the original, it will take 500 HP of NOS to break those welds, not to mention I have made over 400HP at the wheels.

??? What is to thin???
The bellmouths, all 4, are milled out of the same 20(?)mm alu-sheat, and I can't realy imagine how something could fall of.... (JM-fab this is!)

A quick look an some mesuring says its possible...
Just like it says on their homepage!

This car started with a stainless exh manifold , which cracked .
And the intake manifold also cracked , would of been not to bad if it did not cost him a $15 grand eng .

the only way u can blow an intake manifold is due to bad tuning!
SR20 powered starion what have I done..... :P

When running nos , I would aggree .

But the manifold cracked because of being to thin on the flat surfaces , which cracked a weld and changed the fuel mixtures and the low comp pistons failed .

I think the comment about thin manifold is refering to EXHAUST manifold (the Stainless Steel ones) they need to be reinforced etc as stainless is proned to cracking when exposed to vibration and fatigue (heating and cooling)

Intake manifolds are typically aluminium and have thicker walls. I doubt they would have any cracking issues.

I don't see how NOS would effect an intale manifold. Exhaust yes, due to the much hotter exhaust gas temps.

The intake pleanum cracked due to shit design .

Nos backfire will take bonnets off as well as destroying intake manifolds

The exh mainifolds are made from thin wall exh pipe , thats why they crack , to help the exh manifold last longer they req a few braces from the head flange to the turbo flange to stop it bending as it gets hot .

This is what will be happening.

As well as a JMF intake.

Now trying to decide between the Garrett GT3582r and the Turbonetics GTK 550...
The GTK looks a hell of a lot nicer...
I'll post pics, cause everyone loves pics. Haha

those gtk550 are awsome turbo!

i brought one from the us then the place went under.( that sucked and a good thing i used paypal) there really good spool time and are they only oil as well?
