I got a '90 Integra 4-door B18b with 96000 miles. Wanting to build it up. Im wanting to get as much power out of it as possible. Time on money are not a problem. Looking for ideas and advice.

well i mean first you should start with the basic bolt on's like intake, header, exhaust...then you can go further with a better intake manifold and build the motor if you want to go all motor...you could also boost it or even put nitrous on it...

which would give me the most power out of this engine

Turbo will give u the most by far when done right. you can make 500+ hp just depending how extensively built your motor is- as well as an awesome tune- which is absolutely necessary anyway so plan for that

the best power for the money is nitrous...but you need to understand the falls of nitrous

1) is a lot more hard on a motor than boost would
2) only get power when you activate it - not always there.

I had nitrous on a stock LS motor with 145K, drove it for 2 years on nitrous (75-100 shot wet) and took my quarter mile down from a 15.9 to a 14.3

and i sprayed a lot on it, like a lot lol...after 2 years the rings finally gave out

boost it is then. what turbo would yall recommend and what tips on builing the top and bottom ends?

well stock ls sleeves i wouldnt push more than 350whp just to be safe...aftermarket rods (JE, crower, scat) and forged pistons (arias, JE, Weisco) etc..

Far as pistons i would recommend cp. Rods i would use crower or eagle. If money is no option and u want as much power as possible i would go wit a stroker kit. Im currently building a b18 with a brian crower 2.2 kit. And for the turbo either precision or turbonetics. The size will depend on what power u want to achieve. As much as possible is not a hp goal. Everyone will tell u that.

^ forgot about CP, they are also very well
