I have a y7 turbo, with a greddy td04. pretty clean with vitara pistons and a couple other upgrades. planning to take it to the track starting the new year. since im trying to put some miles on this fresh build before i tune it.

Ive been getting people ask me why i didnt go vtech with a y8 or a z6 or even a mini me swap. I did some reading and just stayed with the y7 because w the turbo its not going to be much of a difference. and that a mini me swap tends to leak. lemme know what you guys think.

What do you mean leak? HG leak?


My buddy has had 2 mini me's with no issue, 1 was turbo.

jcuetizzi

yeah, head gasket. i had one before too and changed the dizzy with the harness and everything. but on this car now i just kept it non vtech and just changed the y7 manifold.

i guess my question would be, if two cars had the exact build but one had a mini me swap, would it make a difference if both were turbo?

DO NOT RUN THIS WITHOUT A TUNE! I don't care what your rational is. If you want to break it in then do it on a dyno.

BTW, turbo likes VTEC. Yes there will be a difference. I'll put mine up against yours any day.

X2 on this

And why not run a turbo with VTEC? If you have the option to have it on the car, do it.

Mini me.. im preety sure the y7 intake manifold has the best flow tho

You would be wrong.

well it was tuned before the rebuild. but ok. i have a mini me on it but then picked up a y7 head, took it to the machine shop and kept the y8 manifold. i'll keep it like this for a while. if anything i'll change it back later.

Don't even know why you asked then.

jcuetizzi

just to see what you thought

apexi_rsx

you can acually port a non vtec head out more because there are no oil gallery's running near the ports. they do make more aftermarket cams for the vtec heads then non vtec. vtec on a single cam is not that much to run home to mom about. with a cam and a big port job to a non vtec head would be just as good as a cammed vtec head. ive seen stock for stock turbo builds of non vtec and vtec d series and they both make roughly the same power and it isnt much to gain just having a vtec head. all the non vtec head needs is a better aggressive cam. if the prior tune was on the vtec head and your breaking in the motor i would recommend keeping the motor with the same setup to break it in. do not run it hard unless u have a wide band and know ur tune is running ok.

jcuetizzi

yeah it had the vtec head last time it was tuned.Now i put on the non vtec head and rebuilt the motor, but running the same tune. I just want to break it in before i tune it again and dont want to tune it untill I have money to get a turbo cam. so i can do it all at once to see how it feels.

R u high on crack... the y7 intake manifold is for fuel efficiency its called a bottleneck for a reason...

here if you dont believe me tell me which one looks like it has more flow...



Y7


Y8




Than dont drive the car or disconnect the turbo from the intake and put a normal filter on it cause youre going to blow sh*t up

98civdx

It deffinetly DOES NOT have the best flow. There is a reason why poeple swap the y7's IM's for Y8's.



You need to do some research before you post.

I`m interested in what`s going on here. But, I was under the impression the Z6 had the best flow? Or is it different between forced induction and na set-ups?

98civdx

It might, I don't know.


but he is saying the y7 mani flows more than a Y8, which isn't true.

i have to grab another bag of popcorn....

Wrona

pix or it didnt happen

Z6 and y8 have very similar flows

Libertariat

The y7 manifold, and non-vtec heads are probably two of the worst things honda has ever made.

Both flow terribly.

But you get great gas mileage.

Vtec + Turbo = Awesomeness. The vtec will help the turbo.

HCivExoo

the Z6 head flows almost the same exact numbers as the Y8 maybe just a touch more but the Y8 has a swirl-port design on the intake side to help with fuel/ air atomization.
