by sr20det fwd gearbox i assume u mean putting a SR20DE FWD GEARBOX on a SR20DET....in this case the answer is no....i have a P11 FWD small spline non-lsd on my SR20DET going about 40,000km with a ACT "street&strip" with a Heavy Duty PP. As long as u use the right gearbox oil (GL4 75w90 Synthetic) an remember to change the fluid once in a while you should be ok.


....or an dont drive ett "like u stole it"

what you guys think about a sr16 gearbox on a sr20ve?

i checked around and from what i gather the sr16 gearbox will give a better acceleration but they carry the same 4th gear as a sr20 gearbox. the 5th gear on a sr20box is also longer.
so sr16 will be faster on low end but slower on top end.

also will the sr16 box ratios be favorable to the sr20ve? meaning in the same power band? i know the sr16ve and the sr20ve has almost the similar power bands but the ve can rev a bit higher due to the shorter stroke.


main goal is to be as quick as possible, Not in it for the speed but for the acceleration

But seriously, if it's from the VZ-R Pulsar it will be fin cooled, top/side mount, small spline and cable.

If it's from a VZ-R B15 it will be top/side mount, big spline and hydraulic.

Dont make sense repairing bro..you cant change individual gears u will need to find a complete cluster of gears. Best bet is to buy back a box or go big spline.

Looking for a gearbox for a ve. Going into a b15. Which gearbox would be easily accessible and easy to install? In terms of shifter ect.

Sr18 cable or small spline p11?
I heard that the p11 box is easier to bolt up. Also what crossmemeber is needed?

Don't need lsd but Def hydro.

So what needs to replace the rear bracket?
It's a manual p11 crossmember I'll need to buy.
