for someone with no knowledge and only 3 post your headdin for the high... start slow and learn more first. check all ur options then start aimin for hp's. at the moment you shouldn't be thinkin of no more then 6psi til u kno what's goin on.

 

the exhaust side of the turbo is a 48 from a sabb and the cold side is a 63 from thunderbird, anything over 8 pounds on a zc i would get a good sized t3

 

Just use a 14b

 

Just to let you know:

 

that's like the size differences between toyota truck bottom ends and honda bottom ends, that is insane. what is the d16a7? Does the d16a9 truly have a bigger bottom end? are those pictures correct? or is the d16a7 dinky? I think we need some clarification because those pictures show humongous differences.

 

I took the picture and it is correct.
D16A6 and D16A7 are 1.6 SOHC engines.
D16A8 and D16A9 are 1.6 DOHC, known as DOHC ZC.

 

Ok, so I am in about the same situation as you, except that the ZC is built so I want to run up to about 15 psi. I have looked at a few turbos

T25 - I figure this is way too small for my app.
T3/T4 - .42 A/R COMPRESSOR
.48 A/R TURBINE
T3/T4 - . 50 A/R COMPRESSOR
.63 A/R TURBINE
T3 - ? AR
T4 - ? AR
14B

Given your knowledge, which turbo out of these do you think will give the best performance while retaining some decent spool times for daily driving?

Thanks! (and I did search! ;-) )

thats a pretty odd picture, from what I can see that looks like comparing a D16a6 and a D15b2 crank. Over hear a D16a6 and a ZC crank is the same, they both use the same main and rod bearings. Unless something is goofy about the D16a7 crank or the d16a9 really does have bigger journals than any other D-series.

Reguardless, all d-series rods are the weak point, I wouldnt shoot for any goals over 250whp.
