would the D16Y8 tranny do something if a put it in the D16Y7 engine and what difference would it make if i drop the vtec head also with the tranny

MikeNice

if you put the y8 tranny on a y7 motor then all you will have is a DX with shorter gears. If you put a y8 head on the y7 motor that will make it cool and a bit faster. I hear it only makes about 10 horse more than a stock EX would make.
But everything bolts up. Good luck.

are you saying that a y7 block witha a y8 head makes 10hp more than a y8 block and head?? if that was right, the mini me would make like 137 (not wheel)hp. for some reason that doesnt sound right but i could be wrong

EE_Chris

How would a mini-me have more Hp than a stock Ex??

Bolting on a Y8 tranny to a Y7 block is an EXCELLENT upgrade on its own.

but if i put the ex vtec head and the tranny would it make a difference than just the ex tranny on it

Well....of course it would help.

Slapping on a tighter geared tranny will help you accelerate a bit quicker; slapping on a VTEC head would increase tq/hp which would also help you accelerate quicker.

y7 with a y8 head doesn't make more power than a standard EX. this is because EX has diffrent piston and compresssion rate.

Civiclx

true, personally i have a y7 with a y8 head and a y7 tranny but am going back to the stock y7 head and slapping on the y8 tranny for some more fun, the y7/y8 minime has too many freaking sensors that it is looking for

B7/Z6 ownz j00!!!!

But yeah to the thread starter, a Y7 with a Y8 tranny will feel 10x better than stock, and if you throw a more aggressive cam in there it will feel even better than a Y8

kommon_sense

Assuming that the online CR calculators are correct, a y7 block w/y7 pistons + y8 head will yield a higher CR than a stock y8 setup. So makes sense that a y7/y8 mini-me will make slightly more power than a stock y8.

anyone with a dyno of a minime jump in anytime....

I'm fairly knowledged about this, and a y8 tranny and head will make a large improvment. I would deffinatley do it. then go turbo. lol

i did the y7 y8 minime then turboed, going back to the y7 head because of obd2 crazy codes

I have done y8 tranny swap i am extremely happy with it and i am going to Mini-Me it this weekend. Civiclx what sensors are you showing bad?

rexandfx

Yah what are the problems you are having...Cuz I am gonna do this swap soon also.....just to suffice till my b16.

rexandfx

Bump.....

This statement is correct

Civiclx

im gonna wire up the knock sensor soon, but i havent gotten a clear answer on ht about the fuel tank pressure sensor, i think you need to switch out the whole damn gas tank and charcoal canister and aslo acquire a purge solenoid, either that or wire in a resistor to trick the ecu

So what about swapping the ecu?? And if it would help, which one would you swap to?

Civiclx

you can use teh dx ecu but you have to use the 3 pin iacv

Did you gain a fair amount from the head swap...I mean was worth it?
