240sx SR20DET build help

[vinc3nt1337]

OK,

Im looking to build a 240sx with SR20DET engine. Im new to this, and I can use some help. What I need to know is:


1. When buying a 240, does high milage matter. I would think not, due to me putting a new engine in it.

2. Do I need to buy a new transmission, or does the one for the stock engine fit on the sr20?

3, does buying a better SR20 matter? when im going to put in new: cams, turbo, pistons, intake mani, etc... (I.e. buying a less powerful s13 redtop instead of a s14 blacktop) or maybe i just buy a non-trbo SR20DE since im putting an aftermarket turbo anyway. what would be the most cost efficient for a 400hp build?

4. where do you reccomend I buy everything, I.e: car, engine, aftermarket parts, etc...


Thank you for your time

400hp is a lot. You plan on running pump gas or race gas? As far as internals, arp studs, mls head gasket, good bearings, valve springs with matching cams. 740cc+ injectors z32 maf and a good tune. As far as turbo 400 hp is possible on smaller frame t2 flanged turbos but requires a 82+ a/r turbine housing and usually race gas or pretty high octane and turbo maxed out. If your looking for pump gas power, id look into a gt30 or larger turbo.
