Hello everyone,

This summer i bought an integra 1991 with an b18a1 160k kilo and i got an 2¨ 1/4 exhaus ... i know i will have to change it So this winter i wan to rebuild it turbo i wan to know wich piston and turbo i should buy if i wan to reach 300 whp and more ... I got 5000 to invest in this project and i wan quality parts. And if it worth the money i should invest moreXD. So if someone can help me to shop the good part to rebuild it, i would be really happy because i dont wan to lose money or make the worng dessision. for the moment i think about rebuilding the head and after i will buy the turbo t4. i think loew compression piston and good cam valve and .... so Please help me its my first rebuild...

Ok you got 5k to invest. You might as well sleeve the block and do 84mm to 85mm bore. Get some 9.1:1 wiseco, cp, or je pistons. Also get eagle rods. Balance and blueprint your crank. Send the head off to get PnP and rework. This is if you plan on hardcore boosting..lol

OR

If you motor is healthy just boost it. You should be making 200+whp.
Which is still pretty good for a street car.

Thanks for your answer But i got an other question can i go with 8.8:1 comp. Is it gooing to get me more whp or higher comp rate is better ?? Turbotecnic turbo is good? Wich cams and valve should i buy? What size of injecteur will be required after that and what size of exhaus? Cometic Gasket will be the better chose?


Thanks in advance for your Help
