Umm, the D15b7 is MPFI for starters, and it is around 9.1:1 compression, not 9.7

whats the engine code for a 90 civic lx then? i thought it was a b7 but i guess im worng. i wasnt sure about the compression either i thought it was 9.7:1. either way, its a 1990 civic lx with the stock motor with dpfi.

no wonder you went boom... dpfi and non intercooled... no good.

lol...i know it will go after a while. i dont care. it actually still runs. i thought it blew but it was the rotor in the dizzy. it pretty much blew apart for some reason. maybe because it has 183k miles on it oh well. i jb welded it back together and now it runs like ***. i think my timing is way out in left field.

I went turbo twice and never blown the engine one ZC and one D15B2 with MPFI swap...both had about 190 psi all across. the D15B2 took 15 psi daily for two month;'swith the same turbo I used on the ZC. Sold the car with the D15B2...got rear ended.
I blew my first block this week and it was NA...sucked

I'm going to be doing a Compression test on my D16Z6 this week before my turbo kit arives so I will surely post the results for you to check out OK. I have 202,000km's on my engine just FYI. Check the box to be notified about this topic and I'll reply after I have it done.
