my last na build i did was about 6 years ago. it made decent power. but in order to get that power i had to.
ram air intake, knife edged the throttle butterfly, ported and polished the intake manifold, gasket matched, 91 exhaust cams, decked head, ported and polish the head, had some crazy valve work done. gasket matched, ported and polished a custom 4 to 1 long tube header. that collected into a 2.5 inch exhaust. theres more but i cant remember. stock pistons, balanced rods and crank. i cant remember if i used 89 flat pistons or not. i had a flywheel reworked and balanced. stock clutch(stupid me) crappy open diff.
the ignition system, msd all the way around. timing was set to what ever got me the best throttle response. iridium plugs and some thick wires (cant remember the size)
the fuel. adjustable nismo fpr usually maxed out. this is the area i started running out of money. so i put a sr20 maf on it to make everything super rich and it showed a difference. better power curve and seemed to pull harder, and shitty gas mileage.
over all characteristics of this build was a real snappy response. though i didnt care but it turned out to be very reliable. it pulled hard from 2500 rpm to about 5500 rpm. never had it dynoed or 1/4 mile. but it would do a easy 0 to 60 in 4.9 to 5.1 on avg. i raced cars that pulled high 13's to low 14's and usually won. (not sure if it was my car or their driving, but a win is a win)
final thoughts. there wasnt alot more to do to get power out of it besides oversizing the pistons and stroking it. it was a fun build and left alot of people wondering wtf just happen. but when it comes down to it. it is far..............i mean far easier and cheaper to slap a S/C, turbo, or n2o and get the same results. if i had to guess this made about 200 ish AT MOST(this is laughable by todays standards). when you think about the thousands of dollars needed to make n/a power. you could get a rb20, rb25, rb26, sr20, ka-t, ka-s, ls, or any number of the motors that swap in.
conclusion, this was my first and last n/a build. if you want more then 170 hp from a n/a. you will have to open up the motor and start pouring cash into. so consider what you want out of it, over all. then pick the best route.
