what is the power comparison with same turbos between the inline pro and full race? i know the tublar equal length does the same, but does it make that much a huge difference?

Unfortunately, it is asking for GT35, instead of GT3076R, which I already have.
I know i keep pushing a steed speed manifold but I'm running the turbo you have essentially on it. It's not a requirement to have a gt35 i think they mean that that's the largest it will fit. your turbo will sit rather close to the block so gt42 is out of the question..

Hi Tyraid:

Can you post some images of the installed turbo, from multiple angles for reviews and comparison?

I like to see the options.

What is the size of your downpipe?

I assume there is no rattle or vibration, right?

if you're looking for an Inlinepro manifold and down pipe, check my link in my sig out.

The GT3076 will fit if they state the GT35R will fit since it's really the compressor housing that causes fitment issues (they both have the same compressor housings).

I vote for the Full Race manifold . I am using that manifold in my s2000 and a local shops turbo s2000 track car is using it and there hasnt been any problems

The FR manifold is more efficient than the Inline manifold. At a given amount of gas flow, the FR manifold will result in less backpressure on the engine.

Thats about the only difference from a fluids perspective. The end result of this is:

-Less turbo spool time
-Less boost pressure required to achieve the same overall power numbers
-Higher power levels achievable with the stock headgasket

Cast manifolds are going to work better with a gt35.

I think someone here has the gt30 and took 20 psi to hit 400 rwhp.
19 psi to reach 405 rwhp.

More than meets the eye, however. I was using a VERY restrictive turbine housing for maximum mid-range torque, not maximum top end power. To keep sound down, I retained my HKS Hi-Power dual exhaust which is no more efficient than a stock exhaust. A larger turbine housing and exhaust would have netted me 30-50 more rwhp.

Umm,
I can promise you none of the steedspeed manifolds have cracked, and its tubular inside...
I can't imagine a manifold so overdesigned ever cracking unless you took a hammer to it.

The manifold is certainly not tubular inside. I have a hard time believing that it flows any more efficiently than the Inline. From the CAD model I saw, each individual "runner" is forced to bottleneck at a common collector.

If you call this design tubular, than technically, so is the IP manifold.
