Re:JDM D15b Vtec and boost.
 

Agreed.

Also, I don't think there is a magical "psi" to where it should be safe. It's all in the tuning and how you drive it. Obviously pulling up a hill in 5th gear running 16psi on a T3/T4 is going to be pushing the limits of the stock motor a little bit.

i ripped on a d15b for about 8 months and it loved turbo.

my spark plug wires got in a fight with my pistons and broke some ringlands though.

If they were the same price I would go d16z6, if not go with the cheaper one :P

Re:JDM D15b Vtec and boost.
 

what kinda compression am i lookin at with a z6 head and a6 block? i was worried about high compression and looking into 8.5:1 pistons but i said ---- it , i wanna run 10psi on stock internals running uberdata.. ive been told it should be fine if shes "well Tuned" ..lol besides i have 8 extra pistons layin around ;)

I'm not a big fan of d15's at all, the 1.6's have more grunt and have cheaper aftermarket rods. All d-series stock rods sucks dick.
