That's convinced me I'll bump up the G30-660 to 770

 

Any idea if the difference in boost pressure?

Cheers

Im loving this thread. I have a g35/900 t4 split 1.00 ar going on my rb30/25 with 9:1 and 264 cams. its drive by wire and with vct i think it should spool nicely. I have the 8speed gearbox on the floor ready to go on so full boost changes will be a thing if the tyres can deal with it. it should always be on boost

What do you mean?  In between the two I shared?  They're the same boost

This will be insane.   A mate has a GTSt with a 9:1 RB30/25 with Tomei 256 cams and a Borg S362SX-E that is already a beast from the basement but has a stock 5 speed and will probably get a ZF8 one day.  After the G35 900 RB26 setup I'd be lying if the topic of "Wtf would a divided G35 be like on this thing?" idea hadn't come up - you'd definitely want a wide boost control range setup with it, as even with the less responsive and potent S361 we're having to ramp boost in from very low levels in the early gears.

HKS2530 frame and a newer CHRA plausible? like a g25-500 CHRA in the hks2530 frame?
