Best d16 gearbox for acceleration?

Beeza all cars have a final drive. Do you mean is there a final drive to suit the y4 ? Yes there is.

There is a 4.7 and 4.9 FD to suit your setup....with minimal parts required.

I was reading gas mileage goes out the window at highway driving because you will be sitting on 1000 rpm more on the highway due to the car revving higher?

I can't get that link to work benny..might be on my end.

Beeza, when I changed from 4.7fd to 5.1 in my old k20a, I didn't use noticeably more fuel, worse comes to worse I may have gotten 25km's less a tank, but to me that's not 'noticeable'.

5.1 huge baller
Beeza just google Mfactory and feast your eyes on pure metal sex but I think you need to decide what the cars intended purpose will be. I personally surgested swaping to a more lively stock engine/gearbox as I assumed that this is a car you intend on driving daily and at a fairly significant distance since you live in whoop whoop and since the stock engine is over 300,000km a newer lower km unit might be more reliable long term, that being said if your a baller and don't give no fuks then yeah a close ratio gear set and higher final drive without a full rebuild is an option. To each there own

Yeah a b18c2 low km is the go aye.

There a couple out there.

Change is good.

+rep 4 u guys.

If you got the cash then def go the b18c2, just be aware they will be getting long in the tooth so prepare for box crunching and oil using motor. And don't be fooled by wreckers/sellers saying they will give you warranty, because if you don't pay a licensed mechanic to install it they won't warrant it.
