ok i just picked up a d16z6 and a d16y8. both have spun rodbearings, so they both need rebuilds.

say i rebuild both the same.

9:5:1 comp forged pistons.
eagle rodss,
new bearings, thrusts and they were both cleaned really good.
turbo cam, new spings, retainers, and valves.
which would be better for boost?

id be running 12-18psi depending on how i trust my tuning.

just wandering which one i should build up and why.

also don't post to flame people or just to get your counts up.
only post if u have facts or first hand experiance.

do you have to get a new block if you spun a rod bearing.

D-Man

If your not gonna port the head use the D16Z cause it flows better.If your gonna port then flip a coin cause it wont matter and they are both good engines.

nope

D-Man

oo...just wanna add if your gonna use the EGs OBD1 then use the D16Z6 head so the distributor will bolt right up

I've got a semi-built 95 z6 head from my old set-up I could sell you cheap. Let me know if your interested...I can send pics.

Might save you some time and money on the build up.

Snail Tuning

Pm me the details. ok so im mostlikly going with the z6 head. because of the obd1 and suposidly it flows better.

is the y8 better in any way over the z6 or vise versa?

thanks

Endyne did an article saying how the Z6 Flowed much better at high HP High RPM. I had the two heads back to back and you can tell that the Z6 has a much larger intake port. Also the Y8 head will raise your C:R versus the Z6. Although if you have the Y8 Intake mani, I suggest uyou use it, It has a much larger plenum and intake runners.

obd1 dizzy's bolt right up to a y8 as well. i have a CX dizzy on my y8..even though i spun a bearing last night...FOR SALE

but, use the y8 block and the z6 head. Y8 intake manifold as well.

tap out the holes on the back of the block..and run b-series axles. it's so much easier and stronger to just get some B series axles...cause, d series SUCK

so your saying that you can use the b-series mid-shaft on a d-series block?

as long as you tap out the holes in the back of the block...from my understanding...you can run the mid-shaft and axle.

I was about to prove it...but...um...i just spun a bearing. After i pull the swap out, and i get my b20 stuff here...i'll try it out and get some pics and what not for ya guys.

Snail Tuning

is their any reason i should use the y8 block over the z6?

BS..B series axles will not fit in a D tranny,they are 27 spline and the input on a D tranny is 26 spline,not gonna happen....BTW I dont like the B tranny half shaft and support bearing only = to more **** that can break,especially that support bearing.You want good axles buy DSS stage 3 axles like I did,Zex Man ran them and never broke them running Hi 10s.

ITRswapandslow

sure thing buddy

but i know for a FACT that the d16a (JDM SOHC ZC) can run them. I know that for a FACT.

I'm almost positive than the newer ones can too. I'll pull the engine, and do it..and show you it can.

no
get either
get an a6 block and a z6 head...that's what Matt Patrick ran 10's with

hehe, here comes 9's soon though

The Internet Tough Guy

hey check this link out: http://pub143.ezboard.com/fhon...topic

its mostly a toss up. the intake port dividers are different, so the z6 head does flow better than the y8; but the gains aren't prevalent until you get way up in hp #s. also, the y8 is less prone to detonation.

i'd say for a moderate daily driver: y8
for a track ***** / beaster: z6

ITRswapandslow

talk to any engine builder..and they'll tell you to go with a z6 head

even when fully ported..the y8 still can not flow as well as a mildly ported z6.

y8 heads=TRASH

ITRswapandslow

ohh, and an a6 head flows more than both

Snail Tuning

i read somewhere that the y8 has a more agressive cam is this true would it be worth switching in the y8 cam in my z6 head? also sounds like im just ganna use th z6 head and block so their both the same. makes more sense to me.

ITRswapandslow

if you're going boost....

get the zex 59300 cam, and zex Ti. retainers.

you don't have to worry about vavle springs, ever, being as the stock valves are so ******* light.

if you need head work...RLZ is the best.

Yes a ZC has 27 spline inputs...Matt patrick switch to one and is running custom DSS stage 5s without that shitty B half shaft and support bearing

we took both apart and checked

dude, wait till you see Matt's new stuff. It's been sitting here a while...needs to get on car soon.
