ok, so i just got my 8.5:1 81.5mm srp pistons in w/je rings, locks, pins, and t.washers..., victor reinz head gasket, and clevite rod and main bearings. im going to order a block guard and all arp fasteners...am i forgetting anything really important on the build...im paying a friend that works at a machine shop to bore, hone, and micropolish the crank shaft, w/ balancing. i want to boost at 2 settings, 7 and 15...going a 1/2mm over bore isnt too risky, correct? i have a 94 ls and i pkan to keep it non-vtec due to finance, but i have 158k on the motor and chassis. are my mounts and axles going to be able to hold 270ish whp? and as of now, my car is making squeeking noises like every time the tire makes a full revolution...these are bad ball joints right? whenever i touch the brakes tho, the noise goes away...didnt know if maybe a rotor was warped...no back pressure on pedal though...

let me know what you guys think...i may try to get a vf34 to try to mount as my kit setup...also, 450 dsm injectors are a direct bolt up right?


thx -chris-

 

Sounds like the wear indicators on your brakes, you probably need new pads.

As for your cylinder bore, I would hold off on buying pistons until the machine shop inspects your bores. I personally would want as much cylinder material present on the sleeves as possible for a turbo application. If they need a bore, bore the minimal amount and match the pistons.

You should visit the forced induction forum, its more suited for these issues.

 

Boring .20 over is very common in engine builds. It will eliminate any out of round cylinders giving better ring seal.

Picking up a set of polyurethane motor mount inserts is a good idea to eliminate any wheel hop that could break axles.

DSM injectors will require a resistor box to be wired in (if you don't already have one) and the O rings bored out a bit to work.
