  1. How did the Cam choice go mate? what turbo etc were you running with that cam combo?
  2. Yea the motor is being built to go for the 850+rwkw so alot of people seem to be very quiet in regards to advice. my builder has a lot of experiance building High HP and high boost motors, and to my knowledge hes built 2 RB30DETs and both went 600+kw for years so i trust what hes doing. just interesting to see that no one else has gone big power with high comp on E85.
  3. Hes a good mate doing in his own time so im trying to help out where ever i can. im supplying all the parts etc
  4. Looking to run as close to 11.5:1 compression in my RB30DET (Forged 3.0l Bottom end, RB26 Head, GTX45, E85, Built C4). Any Tips or links as to what piston & HG combination will get me closest? also what block work should be done to help raise the compression? Brad @ Spool Imports isnt sure if CP Pistons will be able to fit enough Dome on the piston to achieve that CR. Cheers
  5. im currently in the process of building a RB30DET (Forged 3.0l Bottom end, RB26 Head, GTX45, E85, Built C4). My engine builder has told me we want a 11.5:1 compression ratio because we are using E85. ill be looking to run 30+psi with this. Ive contacted Brad @ Spool Imports to see what pistons he can get his hands on that would get close to this CR. He reckons that they (CP Pistons) wont be able to fit enough Dome on the piston to achieve that. Another issue im looking at is, ill be running fairly high lift cams (between 9-11mm lift) so with such High compression im assuming ill have to fly cut the pistons which would lower the compression again surely. So what CR have people running high boost and E85 run and how did you achieve that CR (original CR of piston, work to block, HG thickness etc)? also any hints on how to get as close as possible to my 11.5:1 CR?

  7. WTB RB26 head. doesnt need to come with Cams but needs Cam caps included. not looking for a super special one as itll be getting a service and other work done. cheers
