Nissan Primera SR20DET Build Help!?

[Corypaul07]

Hey guys I just recently purchased a 1998 P11 Primera with a sr20det. It has already had some work done to it and is quite an aggressive car but I am wanting to get some more power out of it. I was told that it’s last tune made over 300hp at 17psi but do not know if this is correct. I am wanting to aim for 350-380hp so would like to know what the best way to achieve this would be and if I will be needing to upgrade other things such as brakes etc or anything vital to making sure it can handle the power. I’m not the smartest with cars so don’t roast me. Here’s the dets for the car and yes I realise some are irrelevant but I just copy and pasted it.

Cheers!

nice car dude!! Even though it's a proper bluebird DET engine I wouldn't be aiming for over 300bhp unless you want to run into potential reliability issues on the stock block. Next step would be forging/building I'm afraid. Plenty of second hand parts come up on ebay though, hks pistons/ tomei rods etc. as of late.
