SR at stock boost all day man, I have mines at stock boost and i have lots of fun with it... I am able to spin 225's in the back and tandem with guys making a lot more HP than me. I drifted a KA24de for over 4 years, it was lots of fun... Now i have the SR and i am having the same amount of fun.... cause suspension OWNS... lmao... get the SR leave it at stock boost, it will be reliable... as soon as you get power hungry the drama will start... my sr swap went like this:
SR= $2000
FMIC = cxracing $200
radiator = cxracing $120
fuel pump = $100
wiring = free
300zx fuel filter = $10
for $2430.00 i finish my SR swap... look at around 2500-3000 to finish yours.... i have donw 4 drift events with the SR, no over heating and no problems... its at 7psi.. plus the guy that said SR 220hp at 7psi ... is more like 180hp...lmao
u didnt replace any gaskets or seals before u dropped the motor?? im doing my swap now and i was told with that stuff its better to do it and be safe than sorry later
