f13Cr on c14SE engine

[Twistie]

Will a f13Cr gear box fit on a nova sri engine and all be ok where it is a Cr box what will it be more top end or bottom end?
:tard:

CR = close ratio, which i think will give you better acceleration. As for fitting an SRi engine, i think it will.

[Twistie]

yep i no it is a close ratio box but the top end on my sri is 125/130 so if i fit a Cr box will it take the top end away

[Pistol Pete]

Yes.

BTW, *parts pusher lol* i have a 4 branch manifold FS for that engine......

Depending on the final drive the top speed will be the same.

It will fit as iirc they come with F13's?

Mine did. F13CR with 3.94:1 final drive, topped out at 125 on the clocks (115 on sat nav).

[Pistol Pete]

C14SE's came with both F13's and F15's IIRC. Remember this engine was used in the Corsa SRi aswell (in dis pac form) so may have had a different g/box?

[mikey14sr]

^^ yep, F15 if it was in a corsa, though I think the really early ones still had F13.

if you have a cr box, its top gear is way lower than a wr box.

the final drive will be a 3.94:1 or a 3.74:1

a 3.74 f13 cr will run out at 120 at 6000rpm

a 3.74 f13 wr will run out at 135 ish at 6000rpm as long as the engine will push it that fast.

Mine, out of my SRi, must have been a F13CR then. Had that off the clocks many times....cracking engine IMO.
