s13 sr20det fuel/injector issue

[S14rebuild]

Pay very close attention to taken the motor apart. ALL the internals are assembled a certain way.

Cam caps have a specific spot they go, side there on and direction they face. Same goes for main and rod caps.

All parts need tobe free of contaminants. Need to measure EVERYTHING, check for proper clearance and tolerance. If you do not, ur just tearing money up.


Sr20 are a simple engine to disassemble and rebuild but it needs tobe done 100% correct. Not 80% or 95% 100% to be done right

I 100% agree! I'm gonna take the block to a shop for a honing( well for an inspection) What are the chances that I may need oversize pistons? Should I wait for the shop to tell me? Do you always need oversize pistons when you take the block out for a honing?

no. if the cylinder bores are scored, then the bores may be able to be cleaned up with just a hone, OR they may need to be machined. the machine shop will be able to tell you after they clean the block and bores.

if they are just honed, you will most likely need new piston rings, and to perform the piston ring gap procedure, to make sure the gap matches the factory recommended spec

if the bores are machined, THEN you will need oversize pistons, and those pistons should come with new rings. you will still need to make sure the new rings have the correct gap, according to the piston manufacturers recommended spec.

perfect! thank you so much for the response! I'm taking the block to the shop to get it review. I guess I need to wait till the new oil pump so they can get decked at the same time.

send the oil pump gears out to be WPC treated. Its fairly cheap for small parts.

Shit do the whole valvetrain while ur at it.

I highly recommend #WPCALLTHETHINGS

but at the same time, my bill for WPC Treatment on my last engine build was $$$$. Had the cylinder bores, piston rings, crank and main bearings, camshafts, rods, pistons, crankshaft, and oil pump gears done. this engine better last forever.
