FML, so angry i just wrote a mission of a reply here and when i clicked post it made me login and deleted everyting ARGGGH RAGE!

much shorter version of what i typed.

do two things in your rebuild, make factory sump higher capacity and add baffles, and buy an aftermarket oil pump

http://www.cj-motor.com/store/index.php ... 8629512884

theres one from a company in Australia named Nitto, worth about $1400 australian. They make some great stuff, and have full engine builds making well over 1000 hp.

cant remember the other stuff i typed.... oh and i have a rb20det apexi power fc with hand controller for sale if your looking at upgrading that soon.

cheers and good luck with it mate, you can check out my car on here to see my old rb20 setup if you want

love the work dude!. while everything is out, would you consider using conversion mounts? i really really need a r32 crossmember, and i cant find one anywhere. id buy a set of mounts for you and swap out.

i know its a stretch but i might as well ask?

Since its a RB20 u can't go too big or you will hit LAG. My car is now the LAG king but I don't mind the lag, what happens after is all worth it.

i would but my setup is specially made so the downpipe so it doesn't hit the steering rack why do you not want to use a mount kit there are lots of problems that have to be addressed when using a r32 cross member

ive also been running this turbo now for like * months and it barely has any shaft play im gunna try to use it all season then switch to a top mount setup next year

i also wont be running a front sway bar kev ill be running a rear and a beefy power brace and a giant a** skid plate to protect the oil pan this time lol

i will also be using solid motor mounts for more low end torque which the RB20 definitely needs

i had the car re-tuned after the front mount and it made about 20 more hp but it was also because of the tune.

got more work done on the car still not done but i made alot of progress still need to hook some things back up and redo wiring
