Updated Rb20det BB turbo upgrade.

Ok, now i have finialy installed the rb turbo i got, just rebuild 3000K before i got it, And also installed a new o2 in a factory dump pipe. Now for you in the know and need to know. this is what is required.

The rb turbo is a direct bolt on, Hence it uses the T3 flange, Now if you use the rb20det dumppipe be prepared to grind part of you block off near the end of the dump pipe as it doesnt clear.

The Top oil feed line bolts right on, No problems, The oil return line at the bottom needs to be "adjusted" to fit the diffrent angle of the exit on the rb turbo. So heating and bending it to the right angle works.

the hard bit. : outlet pipe, This require many hours of removing and installing the intake manifold to get the right angle to cleer it, This is the hard bit........ Spend time on this.

other than that, its all straight forward. Im running 9psi and its QUICK compared to before with 12-15psi, my turbo had so much play and wined like a bitch and had bits missing out of the compressor wheel .

9 hours work, not so great

You didn't hook up the coolant hoses? Probably doesn't matter, I plumbed coolant to the turbo from the heater hose connections at the firewall.

Nope didnt use cooling atm, will be setup later on. it doesnt give much advantage apart from letting the car sit a little longer after boosting

i always thought i needed the dump pipe off the RB Turbo for the RB Turbo upgrade on the L20et....*sigh* skylinesdowunder informed me incorrect again....

Yeah. you do need the rb dump pipe or a aftermarket version. Power is great now, Smooth strong heaps of torque. Its now drives like a Rb, pitty tho no more 80's turbo lag kick.

Im only running 9psi but it definitly has more power than my other running 8psi which i did 109rwkw on. im thinking of around 115rwkw easly on 9psi
