Hey guys,
Just on that subject of when boost comes one at what rpm, I have a r32 GTR and I put a gt35r with a tiny .63 rear housing on it with ext gate, I was after early spool for easy street driving and a more useably torque curve. With 15 psi and 310 rwkws it comes on boost earlier than the standard twins did and holds great boost and a firm curve to 8500 rpm.
When I had decided to go for such a small housing I was warned by many modders that I would get pressure and heat problems due to the housing being to small but all it has been is an excellent street setup.
Oh yeh and thnx for the ratios guys I will most definatly be keeping my gtr diff.
Cheers.
p.s My mate is as we speak setting up his rb30 bottom with 34gtt head for his drfit 32gtst he also is running ext gate and a .63 housing will let you know how it goes.
