Best gearbox upgrade for my 320bhp UK 2000?
 

Ok, so the engines finished, just had it mapped and she's running about 320bhp.
Going up the cogs from 1st through to 4th she pulls like a f***ing train, could'nt be happier, but as soon as you get into 5th??? well, i wish i hadnt wasted the fuel!!
5th gear is so long in these boxes it ruins the whole thing.
so, my question is, what gearbox can i fit straight on that will make a real difference?:confused:

Could be wrong here, but isn't it the power of the turbo/engine which would improve your 5th gear speed?

short ratio boxes are massive amounts of fun... acceleration is unreal, will feel very nice at 320bhp. anything from a classic RA.

A compromise would be a JDM TY754 ver 5/6 sti box, would give great acceleration and still driveable on a cruise

V2 Sti Ra box gets my vote. shortest box of them all. gutted to be going 6 speed.
Banny since when did you compromise mate ;)

Does your first gear take longer to spool up than 2nd and 3rd?

My classic RA Box was great im running 320bhp as well... Turbo always spooling nicely through the gears.. fantastic... nailed you back in the seat. Top end drove me potty though... 70 Mph at 4000rpm... When first gear synchro failed fitted a TY752 STI box with longer ratios ... still fun and better on motorway... Not as much fun as the RA box though. Now got a 6 speed box.. Same ratios as the RA but with the long sixth for the cruise..
28 kg heavier though and about 15bhp more power lost through transmission.....however they appear to be bombproof.. thats the tradeoff.. Get a 6 speed :norty:

Interesting.

5th is just such a long gear and mine doesnt get on boost until about 3000rpm:sleep:

Light weight fly wheel may help.

Does the 6 speed bolt straight in or do i need some sort of mod/adaptor?

Having recently done 4498 kms in a week around Europe in an RA I would have loved the long 5th gear. But as an RA is built to sprint, not cruise and only weights 1190kgs, that's the way it is.

:thumb:

So what everyone is saying is an RA box is the way to go?

Is this a straight swap over with no messing around?:wonder:

Same ratio's as the classic RA box ????

Surely not? if it is then I'm buying a six speed tomorrow lol!

Best option is to get a gearbox made up, then you can choose which ratios you want, but is expensive...
