Rb26 Exhaust Manifold

[sav man]

My Turbos are ment to be finshed and back to me by next week (only been like 2 months)

I'm considering upgrading the exhaust manifold while the turbos are off.

I saw the Tomei kit on nengun for $1144 delivered Tomie Info, I thought it seemed pretty good. The kit comes with a heat Bandage, Clamps, and most importantly Stickers

But i'm also considering the UAS honed and heat treated stockers for $790 + delivery.

Is the tomie kit worth it, or is it just paying for a Jap brand? Or should I keep the stockers?

The reason I was wanting to upgrade is cause the exhaust housing on the turbos is ceramic coated (there the old 2530's from the Paul and Stacey's car), and I thought I might as well get heat treated manifolds to go with them.

Thanks

Id try the unique manifolds, as heat retention is the key to aiding gas velocity....and the thick walled cast manifolds do a superb job of doing that, do you know if they are ceramic coated as well?...good luck with the upgrade....those little turbo's sure were good for us...i hope they serve you well.

the UAS site says that they're HPC coated, is that ceramic?

Yep id go for them for sure, the coating is worth $300 a pair, the extrude honing is probably about the same. So to save yourself the trouble of doing it yourself....get em.

What turbos are we talking about?

Those Tomei manifolds look like a work of art.

i'd go with the stockers, which have been fiddled with.

as i have now seen mentioned above,

The other option is a pair of genuine N1 Manifolds. Then you also have the advantege of having the correct size outlet to suit the turbos.

just take the die grinder to the stockies

ceramic coat if you have coin

EXPREME!!!!

they look hot

Looks as though they leave the lip into the turbine housing there. Wonder why? Cuts into the flow at least 4mm.

Tomeis look nice though. Investment cast tubing. Would be a real dilemma to decide.

The stock manifolds crack around the outlet if you remove much meat from there...that's probably why.

[fatz]

the outlet is where the money is at getting rid of that 4mm = 3psi extra boost on stock wategate pressure

[sav man]

The thing I liked about the tomie ones was that they have a bigger outlet (according to the site). how much of an advantage would that be?

now i want to go home tonite and pull off my turbos and manifolds to have a look at what going on.

but i think i have witnessed turbos being pulled off before, and i dont want to go there.

[fatz]

gtr turbos are a 4 hours job

and or a slab of beer

[Guest Mashrock]

haha, i dont do the beer tho, makes me sick... how unaustralian...
