is it worth turbo'ing my DOHC ZC?
 

Hi there, earlier this year i blew my stock motor and put in a ZC (in place of the si motor - figured why not) but now getting ready for the next step and am wondering if it's a viable to turob this motor, it know it's a super low compression 9.5/1 or something like that...or should i just put in something else (i presume a b16 of some sort)and then save up again and turbo that?

lower the compression the better for boost....but of course you need to build your block to handle the amount of boost

i've seen turbo twin cam zc's...good stuff=)

but is it difficult to build up the block? (cause parts are hard to find)?

if its your daily driver.. i wouldn't boost it unless you know what you are doing.

if it was me, i would boost the zc, screw getting a b-series

:eek:

it is my daily driver - is this a major concern? i would use a system with a boost controller, so i can play with the boost levels...i wouldn't want to stress the engine out on a daily basis...only turn it up if i was at the track...

you can have a boost car as daily, just like most stock turbo cars... a small amount of psi with proper tuning will make it a great daily... if you wanna go track it... raise the boost.. and put in another map that was designed from tuning on that many psi

Turbo it. You dont even have to build the block if you dont go above 200hp.

doesn't matter. If you aren't very handy.. you might end up paying a lot in shop bills.

I suppose, what i'd like to know, is if the benifit from being able to run higher psi (due to lower compression)on my DOHC ZC still remains a benifit after one considers the higher HP figures of a stock b16?

What you should concern yourself with is the amount of power you want from your car, and the budget.
If your goals exceed 300hp then get a B. If they are under, stick with the D. Under 200hp you dont need to build the block, and for more then 200 you do, but the money you save from swapping a B can go towards doing that.
In other words, there is no benefit to the low compression of your D because to see the HP numbers that would affect the compression you would need to build the block, meaning a different set of low comp pistons.
And the B doesnt have much of a HP advantage. It's in the overall strength and design that the engine differs. It has an almost perfect R/S ratio, which means less stress on the sidewalls, which means it is able to rev higher.

hey, thanks PREMIUM DUDE.

I had to look up what an r/s ratio is...but it all makes sense. thanks guys.

i know a guy who's been running 14psi on his stock internal zc for over 5 years now without a problem.

boost it.

what sort of HP/times is he running?

DOHC ZC+7lbs boost+good tune=Happy Mattds.Boost that biatch.

just get a greedy kit put that one there with some sort of custom ship or a afc or greedy emanage

or build a custom one

either way 150-160 whp is easy and you will be mroe than happy with that

lol chris soo thats why you blew the motor eh?

haha:p

whats up with the car now man??

what's our driveling loss? (well approx.)

i'm not sure what he has for numbers. i don't think he has had it out to the strip. he has it tuned on zdyne.

forget hp numbers... torque is your best friend... turbo DOHC ZC... i think that thing would make some decent torque numbers with a blower on it. b16s are gutless... unless turbo'd...
