Turbo Build D16Y4

[Lukezen27]

ok... if u guys jsut gonna come here and say dont bother d series are shit blahblahblahblahblahblahblahblah gtfo dont need it thanks

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

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

[Sexc86]

Your missing the point..

D VTec only adds about 5-7kw max N/A

Once boosted even on a build D that disapears..

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?

[Sexc86]

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

[lookingforboost]

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

[B20NA]

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

[CRXer]

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"

[B20NA]

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