He's right though

The ZC is the best D to turbo hands down...

I'm not says don't do it, just research heaps before you start buying :thumbsup:

ZC is the Jap version and rare as while the D16a8 is the AUS version still rare but not as rare..

Not sure you'll find one and if you do people want $$$$$$ from them...

Yeah is the SI motor DOHC Non VTec

Once build the are killer motors and shuodl be stronger then the SOHC whith better Torque too

On my boosted D I got the following with VTec

VTec off 120kw
VTec on 124kw

In fact not having VTec can help in running higher boost on a built motor..

You need to reseach that stuff man

That's not the case with B's as VTec adds heaps more power N/A or Turbo.

So save the cash you were going to spend on the VTec head and put it towards other parts :)

Not the point. The advantage of have a Vtec head isnt the fact your getting Vtec. The Size of the ports between the Non Vtec and Vtec head is what makes the difference. I Actually have a photo of a Y4 head (non vtec - right) Vs y8 Head (Vtec - left). Both were ported.

Just port the Y4 Block man...

Why waste all the time and money?

To build a head (Valve train, cam, Pnp etc) Will cost the same amount. Just depends on how much he can pickup a Y8/Y1 head for. That will be the cost difference.

A worked Y8 head will flow more then a worked y4 Head providing the specs are the same.

I see

Well then nice info :thumbsup:

i have 2 he he........... thats what i am doing using the bigger port sizes and putting the largest cam in custom designed for my turbo motor that will let me rev to 7500rpm + on the set boost level i want.

just go for it man at the end of the day if you do a lot of the work it will prolly cost the same as putting a B18 in to do all the work to your D and have more power :P

i wont swap for a B caz if i was going to swap to anything it would be a K

i have a D16A8 DOHC with low km's sitting in my shed

my old D16A8 turbo build made 205 fwkws @ 21psi with only t28 S15 Ball bearing turbo

yeah luke D16A8 arent rare lol,if u cant find one on here they are a dime a dozen over at crxaus,i sold my old long block for $150.

^^^that musta been one hell of a build to hold 21psi reliably in one,i would say more than "only a t28"

It was a very tough engine, stock sleeves with a block gaurd but modifield for better coolant flow, gt28 .64ar.
