Hello new to the forum. I have a 1990 300zx N/A and have been able to modify my car in order to have a rear mounted turbo installed underneath where the spare tire wheel well used to be. I've used a T3 RB20 turbo at 5psi with an internal waste gate and BOV. I have less then $800 into it and every part is new including the turbo purchased off of ebay for $239, oil pump for $99, y pipe for $20, T3 flange adapter for $30, 8 feet of 2 inch exhaust tubing $45 Bov used ebay $25 and $140 paid to the exhaust to be welded and bent properly. $50 worth of brake lines, adapters, clamps, vacume lines and fittings. $10 for radiator hose, and $35 boost gauge. $100 for high volume fuel pump. Bascically I removed the two mufflers from the cat placed 2 s bend pipe in their places that led into a y pipe. The single outlet side has a t3 flange welded at a 45 degree angle to which I bolted the turbo. The pressurised side is fed to the front of the car using 2 inch exhaust tubing with to l bends that eventually get tied into the air mass sensore. the exhaust side as a 3 in l exhaust pipe that acts as the exhaust tip. No need for muffler because the turbo quiets it down. I'm currently running 5-6 psi and it makes a huge difference. Sounds like a jet plane when launching and hard accelerating. Under normal driving it kicks in around 3200 rpm . believe it can be done. I'll forward pictures if you want to see.
