I go D14 engine, and will put turbo in it within next two weeks.
What I already got:
Vortech FMU 1:10 (yea, yea.. I kno, AFC would be better.. but...)
in-line fuel pump
hoses for oil already done
Garrett T2 turbo
IC
gauges (air pressure,oil temp and A/F gauge)
SMT5 electronic to retard timings

Anyway.. planning of boosting upto 7-8psi, and engine has compression ratio of 9.2
Do you guys think I need to lower compression range, or will 9.2 be OK? Don't really want to blow engine... so asking for advices/experiences.
If I should lower compression... what would be most psi I could put on stock engine with 9.2 compression?

you'll be fine w/ 9.2:1 w/ 6-8psi. d14?? what year civic is this?

What
Well the PSI should be fine and the stock head gasket will hold up but you can get a copper gasket if you want. I have seen 15PSI on a all stock motor so you should be good with just 8PSI.

Tnx for info

Yes I'm from Europe - Croatia.
Engine is D14A4 (90HP).
I kno many asked why this engine, and not get biggger one and turbo that one... hehe.. cause it's fun
Maybe latter I'll get D16 or B16...

upgrade to a D16, that's funny.

You should be fine, just take it slow and you'll love the boost.

with that SMT5 you should be able to tune your fuel injectors a bit to....or get bigger injectors and tune it with that..

my friend have installed a turbo on a d14z2 engine 90HP stock
it works fine, there is no Vtec but the turbo kicks ***


1,4L 160HP not bad

BTW you have to lower compresion ration with a thicker head gasket or whatever.\
The stock d14 rods are thins like pencil.
I ve seen 2 blown d14 motors on nitrous and one on turbo
soo be carefulll
d14 isnt a good tuning base anyway, its like boosting a 1.3l and having the same perfomance as liglty tuned d16 NA
