Do I need to worry about dif ratios?
Is a lightened fly wheel worth the bother?
Anything else to consider?
Ta :)

I'd have thought you would have been wanting to fit an LSD with the manual 'box Chris?
I think Serek ran a lighter flywheel (from C20XE IIRC) in his car anyway, but if you want a bespoke lightweight flywheel let me know, as I have a contact at TTV Racing, who specialise in flywheels.
Good luck with the conversion anyway! :y
-
Thanks T. I have an LSD in the garage. Suppose I should check what ratio it has. Presuming 4.22 or whatever it is. As opposed to 3.9.

Bloody hell. I'm loosing the plot here, double posted. ;D
Flew turned brain to mush. :(

I must admit I never thought I'd see you convert yours to a manual. As much as I love my manual 2.6, the manual Omega box isn't great.
I've got an ex TVP manual 3.2 estate if you want to blast around in one for a bit, check compatability of parts etc.
-
Check the diff ratio carefully. Manual boxes are geared shorter than auto, so with the same diff it'll be shorter gearing. With a 3.2 I'd say a 4.22 diff would be too short. 3.0 manuals had 3.7 and were still geared shorter in 5th than an auto, not that that's necessarily a bad thing unless hitting the rev limiter before 150 MPH is a show stopper. ::)
a 3.2 auto has 3.9 diff by default, so I'd try it with that at first, then see which direction you want to go for an LSD.

would you mind check if your 2.6 and 3.2 have same rev on 70mph??
as 2.6 are fitted with R25
3.2 have R30 gearbox that shoud have 5 th gear longer.
thanks

Not R28?
2.6 and 3.2 will have diffeerent diffs I suspect
-
Hmmm. 4.2 dif currently. Suck it and see.
First glance at speed range chart suggests 4.2 gives 25mph in first,with top wack at 140, which sounds a bit short... but then 3.9 gives 27 in first and 150 top wack.
Acceleration will be good but changing gear in quicker succession might be tiresome. I guess we'll have to see. :)
I do miss blipping on down changes.

what I like with 4.22 diff car go on every gear same from 0 to 140+ speed just keep going :)
with 3.9 diff will go over 150 easy , but where you going to drive this sort of speed in uk? ::)

Exactly why I fitted 4.2.
Divided by 5 gears, instead of 4, hopefully the effect will be more dramatic. :)

swap for a diesel 2.2 diff? 3.45 ratio then :D
-
the one in your garage is 4.22 !
I'd stick with the standard set-up at first, but paying careful attention to the change linkage.
Other than that, I'm planning a BMW linkage and a lighter flywheel.

You're going to need a big suitcase! ;) What are you going to bring back? I'm guessing something(s) big, GM and with the right number of cylinders..
