hi im new here need some help on what i can do to a stock b18a motor i picked up an 1990 integra rs going to rebuilt it but dont know if i should go allmotor or turbo dont want to spend to much but im going to built the bottom end somewhat like shotpeed the stock rods and micropolish the crank and balance it oh and arp bolt for the stock rod i guess stock pistons and new ring i will be driving the car as my daly driver. thanks

If your staying with a mostly stock bottom end I would just turbo it, due to its lower compression.

ok then if i go turbo what kind of head gasket should i use and arp head bolts and on the head can i use stock valves and 3 angle valve job what do u guys think and if i go allmotor what kind of pistons should i use on a stock head with a 3 angle valve job and stock valves i would like to take it up to 8000rpms too.

turbo: you can use a oem headgasket and that's really up to you if you want to use arp, it's better since it will be under pressure.

All motor: If you want a gas friendly motor than i wouldn't go past 11:1 (you can use oem pistons to bump the compression up i.e. p30, pr3, p72, p73, and pct.) If you want to make power bump that compression to 12.5:1 on up. You can get forged pistons for this.

Your valvetrain for you to rev higher to 8k you need a good valvetrain. Get your crank balance and buy a girdle. If you don't your bottom end will come apart. Girdle help by strengthen up the bottom end.

of these pistons whice one will be best p30, pr3, p72, p73 im going to use the stock head with some mods like i said before 3 angle valve job and stock valves . thanks for the help guys

Which one are you doing first? Boost? All motor?

All motor: p30

Boost: keep it stock compression or if you want to bump it up just a little then put the p72 in. But better to put forged in.

Also, plan to spend quite a bit on tuning and I would if at all possible... if its in your budget by a water/methanol injection kit.

im going to try all motor first if i like it then ill stick with it if not turbo i have to motors to play with i wanted a b20b so bad but cant make it smog legal i live in cali so im sure you guys know why

Yea i know how that is in Cali. Goodluck on all motor.

hey thanks for the help guys
