Hey everybody.
Im new here.
Wanna say awesome site, and i also like how the search feature works ..nice.
I have a 1993 240sx Fastback.
My setup is the following:
Red Top SR20DET
Compeletly rebuilt (stock)
Greddy type S BOV
Greddy Dual Core Aluminum Radiator
Greddy Extra Capacity Aluminum Oil Pan
Front mount intercooler (24"x8"x3")
Earls oil filter relocation with earls oil cooler all connected by earls stainless steel braided hose and anodized fittings
Electric water Pump with block off plate
Flex-O-Lite dual 12" electric fans
Ported and polished turbo compressor housing
Ported and polished throttle body
Ported and polished Intake manifold
S.P.E.C. Stage III Clutch and pressure plate
TODA 4.6Kg Lightened aluminum flywheel
Warblo 255lph Fuel Pump
AGX 4 way adjustable shocks up front
AGX 8 way adjustable shocks in the rear
Ebich Lowering springs 2.1 in front 2.2 in rear
Front strut tower bar
Rear tie bar
APEXi 1.2mm head gasket
Silvia S15 exhaust gasket
Equal Length Stainless Steel Exhaust Header
APEXi N1 (Turbo) Exhaust with straight pipe
APEXi S-AFC
Blitz SBC i-D
Blitz Powermeter I-D
and gauges.
it needs to be tuned but im trying to guess how much power im putting down right now.
Ok also the car doesnt have LSD.
whats a good one on the market that i can find for cheap?
I know i can find Used R200 LSD units at a few places but i dunno if i should go aftermarket.
Also would a R230 rear end work?
I also want to upgrade the turbo and injectors, but i dont want that much lag.....and what i want is a setup to beat my dads 2003 Z06.
Also whats some other mods i should look into to make more power, as i dont want to open up the motor just yet as money is tight.
and one more question... i couldnt find any nice Carbon Fiber hood for a 1993 240sx fastback... i do plan on painting it cuz i dont think i like the rice look but i do want to cut weight off this baby, anybody know of any nice ones with vents or anything?
Thanks.

Mike
