i got a 99 civic ex and im just looking for a little power. im not talking like 2 fast 2 furious style. im just wondering if i should build on this d16. and also what do i need for a nos setup on this.....pistons connecting rods?

Heh heh you want a car with more pep and not f and f so bring up N2O ..interesting. well n2o is fast but doesnt last i would go turbo. you have the power when ever you want it instead of killing your tank...on a back road. if you go n2o or turbo i would say upgrade your fuel system very well. (fuel pump, fuel management unit, injectors, pressure regulator, fuel rail) after that pistons and rods. if you do all that i would say you could run 10psi on turbo and about 55-75 hp shots of n2o. if you go n2o ...just make sure you spray at the right rpms. :iceslolan

uhh 10psi and a 55 shot will crumble a d16 block :-p

depends on what size turbo you got.

lil power as how much more ? I/H/E kinda gains maybe little more?
I would say best is swap out for a b16 and call it a day.
But if you want to keep your SOHC a cam I/H/E and a 55 shot should keep you happy.

the d block is no different stucture wise than anyother and yes it can hold 10 if you upgrade the rods and pistons. the block.... the block will be fine

I think what quicksilver ment was 10psi AND 55 shot but 10psi OR 55 shot. But still 10 sounds high to me for a stock engine but with rods and such i could see it happening

10psi is not a lot for a stock d series motor. I ran 10psi daily spiking to 12psi all the time for months, and the motor had 145k on it, and then I decided to upgrade my turbo setup. I did a compression test to see that the motor after being boosted like that, and being 1 years old was 195psi across the board :)

you can go higher then 10psi ons tock internals but it's all in the tuning. Tuning is key in any setup. But you figure it depends on the turbo size psi has really nothing to do with it.

It's all about the CFM's and how much the turbo flows.

My 14b mitsubish turbo which was the one that I ran at 10psi spiking to 12psi prob. only gave me maybe 170whp maybe even a little less, my new setup:

Turbonetics T3/T4 @ 7psi i'm pretty much at or about 200whp now if I pump it to 10psi and add a 55 shot of NOS i'll blow my motor, or prob. snap a rod unless I get it tuned really well, but both my setups have been self tuned since the only shop out here likes to rip people off.
