Tomei Expreme Manifolds
2 X GT RS's
Mines dumps
HKS 70 mm into 80 mm front pipes
and a Trust MX 3.25 inch cat back i think it is
Big enough for roughly 400 KW at the rears (give or take a few KW)

I have the tomei stroker hidden in a GT block.
Turbo's are HKS GT RS's with Tomei Procams 270 @ 10.25mm with a ported head.
Fullboost (1.65 bar) @ 4800 RPM in 4th (give or take 100 RPM)
Wouldnt change a thing. At times i wish i had maybe 2530's but it really isnt that bad.
Off the top of my head
V spec is 10 mm lower
Slightly stiffer suspension
A-LSD light on the dash
Active rear LSD
Quicker ATTESSA (ATTESSA - Pro VS ATTESSA)
Thats all i think
Motor is all the same. Gearbox the same
It's primarily a street car but i did take it to wakefield once. Ran without any problems at all, even after 25 laps @ 1.6 Bar and oil temps reaching 120 degrees.
Motor has been built with 2 thou clearences.
Well In my car, R33 GTR with the Tomei stroker kit with NON cooling channel pistons running GT-RS's at 1.6 bar and ive never had a problem. It was built by another member off this forum who happens to be a very close mate of mine. So unless you looking for over what the RS's can produce power wise I cant see you needing them. The car to date has run a 11.2 @ 130 MPH so it aint no slug!
Tomei 2.8 litre stroker.
Same kit for both RB25 and Rb26 motors
77.7 mm stroke
119.5 mm rods
either 86.5/87/87/5 mm pistons with either non cooling or cooling channel pistons.
Convience? What about your diff, gearbox and what ever else. Turbo's aint the only thing that should be cooled down. If your fanging it up until u get to your destination then more fool you
Waste of time and effort IMO.
Step 1 just has forged pistons without the coatings.
Step 2 has - a nickel plated & piston surface has a final molybdenum coating.
Step 3 has - nickel plated & piston surface has a final molybdenum coating as well as 22 mm pins
All cranks are full counter weighted.
