RB25 Drift Build Question's / Advice. Chasing some basic advice for the finishing touches and general opinions on my RB25dett build, this motor will be primarily used for drifting and run on e85. The build so far... Block bored and honed CP pistons Eagle rods ARP head bolts ACL race bearings 1000cc bosh injectors N1 oil pump Upgraded water pump Gates timing belt Fuel rail Custom forward facing plenum High mount steam pipe manifold Pierburg external fuel pump, walbro in tank pump + surge tank Trust fmic Alloy rad Turbo I am unsure of the best turbo to run for my application. I do have a Garret gt3582R + external gate, which I got second hand, but has too much shaft play. I have been quoted upward of 1k for a full rebuild from MTQ Engine Systems. Should I repair it and run it, or get something more compatible? What should I be looking for? Obviously for drifting I want fast repsonse and not a lag monster, I am not chasing huge numbers from this build, reliability and good repsonse is the goal. ECU Motec M8 External Head drains I have heard really conflicted things about external head drains. Are they worth it and effective? I was looking at grabbing the Spool kit? And I will be running a catch can. Should I run an oil cooler? This is my first 25 build so be kind, I am only a grasshopper. Any valuable input appreciated.
