I'm gonna be running B18B with t3/t4 turbonetics, 54 trim, .63 A/R. 450 DSMs, spearco IC, SSQV BOV, tial 38mm WG, 7 psi spring. drag manifold, etc etc, stock block, PnP head(being built right now) with 140,000 miles on it on Uberdata. I don't burn any oil. I don't have any clouds coming out the back of my car. On the compression test I got 175 across the board except for #3 I had 162, but I have some valve issues there I know for sure so all should be cured with the new PnP head.

I only want to boost 7 psi, dyno tuned. Until I find another block I can build up to boost more. WILL my motor be safe on 7 psi with the mileage it has? People are saying I have to get new bearings....and I'll have to get some forged pistons and all this jazz. SO if anyone knows how my motor will handle 7 psi let me know. My turbo is relatively big but not really, should pull hard as hell after the lag. Let me know what you all think, thanks in advance (94b18b1teg)

 

140k miles is a lot.

Turbo it... when something breaks, then its time to build the block.

 

bump it up

 

bump for some more opinions.

 

I'm in a similar boat, and I'm just going to boost it until something breaks. I'm expecting the headgasket to be the first thing to go.

 

well I'm putting a fresh head on before the turbo, with a brand new felpro headgasket, so that should be fine. the ONLY thing I'm worried about is my rod bolts stretching and letting go, or the bearings.
