heads and bottom ends

[viinnh]

is this true that aussie model of a D16Z6 head is a D16Y1 head or D16Y8 head

and also is the d15b4 (GL EG) bottom end the same thing as a d15b7 (GLI EG) bottom end ?

[markismaximus]

AFAIK the american D16Z6 is the equivalent of the aussie D16Y1

[viinnh]

ahh okay thanks for that, althought i looked at wikipedia specs thier both different. d16z6 is weaker then the d16y1, vtec cross over is at diffrent rpm's

also do you know if a d15b4 dual carby bottom end is the same as a d15b7 efi bottom end ? d15b4 from a gl eg and d15b4 from a gli eg.

[will13]

pretty sure its the same thing

[dougie_504]

Yeah Z6 and Y1 parts are interchangeable I believe, as well as all their aftermarket parts in case you're looking at USDM stuff...

[mugen_ctr]

i was under the impression Y1 an Z6 are the same, just stamped differently cause of the markets

[will13]

Slightly different sized intake manifold, and combustion chambers. Basically no difference and essentially the same thing

[viinnh]

thanks guy's how about the d15b4 (GL EG) bottom end the same thing as a d15b7 (GLI EG) bottom end ?

[will13]

I don't think they're the same, and the price will depend on SOHC/DOHC and brand mate.
