Section8 talked me into studs, I wanted to use oem bolts since build book says they are ok for my power levels...not to mention cheaper. About the pistons I may just see if wiseco can make me a 9.5:1 piston...bc I sure as hell don't want 8.9:1...and I don't think diamond makespistons for the 2.2, I saw them for the lsj

Even with my 8.9:1 cams and head the motor needed alot more fuel up top so it has to be making more power even with the lower compression.

Ill order the pistons lat as they are the most expensive part of the build :p buying everything over time, not at once. So first Ima have the head checked to make sure it's good for use, have it decked, 3angle valve job, and have it PnP, than imm be picking up the parts needed.

My goal for next year is to be pushing 300+whp on a tvs and a built engine, maybe after that I'll work on making the car look better :p

remember to get bigger o-rings when you put the fuel injectors in. if not the injectors wont seat right and you will have a big as vacuum leak and wont idle....trust me, i had this issue and figured this out last month

i havent had a issue with my injectors not sealing right on the injector ports on the head, i run 60lbs injectors, so they are plenty long to reach inside, and they are not porting my injector ports right now i have no poblems holding boost, dont see why doing all these mods would change the amount of pressure my blower puts out...
