Hi I drive a 96 hatch with a d16y7 in it. My timing belt snapped at 65 mph so you all know what happened ha. Just wanted some opinions on high compression camed d16 vs boosted d16. like comparing gas prices, and reliabilty because it is going to be my daily driver. i plan on boring it out .20 over no matter wich way i go because i am getting one of the kits from fjditributors.com. i just want to know which is more pratical and faster of course

Horsepower goal?

PardonmyEK9

well maybe 220 boosted i dont even know for high compression

blackmugensivic

220 can be had on a stock motor with a little bit of boost

Best bang for the buck on D-series would be boost. Some new rods and pistons and a turbo kit would be pretty cheap.

dragonxiong88

Unless you got deep pockets boost is the cheaper and more cost efficient way to go.

N/A on a single cam isn't worth it.

PardonmyEK9

what am i looking at on 9 psi with 75.5 bore vitaras?

Stop with all the PSI crap. It doesn't matter until you chose the turbo. If you're going to overbore the block and build it you can run a lot more horsepower. Pick the turbo capable of getting you to the horsepower you want to make. PSI will just be a byproduct of that combo.

PardonmyEK9

alright what turbo do you reccomend then if i have stock rods 75.5 vitaras. Is it worth getting oversized bearings

Boost. D series are money pits for NA builds.

What are your power goals? Answer this question before you do anything else or ask another question.

TURBO!!! a fully built NA D Series is very expensive and it will be cheaper just to put a turbo on and have a good tune...

PardonmyEK9

275- 300

Here are some links to the magical 300hp number and what it takes to get there.

Also a cool app by Garrett.

If your timing belt snapped, I bet you just have some bent valves. Upgrade your valvetrain and do a mini me. A light boost build will make you very happy.

There's no need to build the bottom end when it's likely only your valves that are messed up.

PardonmyEK9

i have a z6 head and a p28 im about to throw on it

PardonmyEK9

so stock rods or forged rod if im not upgrading the map sensor?

PardonmyEK9

Oh yea thanks for the links grumblemarc

PardonmyEK9

What about is a good PTW clearence also

grumblemarc

I'm quite sure you will have to upgrade the MAP sensor for the HP you're looking to put down. And what do the rods have to do with the MAP sensor?

PardonmyEK9

Well a stock map sensor only holds 10-11 psi right? so if i have stock rods idk how long they will last

You're talking about building an engine and boring it out then WHY would you use the pencil thin stock rods? At this point I would recommend you look over the build threads in the FI and NA forums. Plenty of examples of what people are running there to base your build off of without all this guesswork and incorrect reasoning.
