How Much boost on built B18B1?
Im getting ready for the big boost soon. This engine was just built...it still only has about 500 miles on it so it has plenty of breaking in to go. Im just wonderin how much boost i can really run on this thing. Its a 94 b18b1 block 81.5mm bore. Weisco 9.1 compression pistons. Eagle H-beam rods. ACL bearings. STR cam seal. Turbonetics T3/T4. HKS wastegate. Im planning on just running around 7 psi for every day driving, but i am able to have two other boost levels at the hit of a button, so what would be a decent number for a high boost level and track day boost level? I know it can take plenty more than 7 which is what my other non built engine runs, but how much is too much for the built one? thanks for the advice.

i think you could run along what zappas said...just make sure you have good spark.. and the car is tuned. Arnel aka thermafi'd16 runs 14psi all day on stock internals and has never knocked..

ok well 15psi sounds good to me...thats around what i was thinking...i dont know about everyday...im tryin to make this engine last as long as i can, but its good to know i can go above that. My other question is about tuning. Is the hondata 2b everything i need to have my engine tuned properly for 15 psi? Because that is what is going on it. im not really sure if im the right one to do the tuning, but considering there are no car places around me, i have no choice! ill definately be asking about that stuff later.
