Auto to Manual Swap

TopPrelude · Post by **TopPrelude** » Tue Apr 29, 2014 8:52 pm

Hi people,

For those of you that don't know me I have been pushing an Auto Lude (1993 JDM Si Vtec) for that last 10 years.

Well i just bought a donor car today to rescue the old girl. Only thing is although I ideally wanted a JDM manual with the M2B4 LSD box it was hard to find one, so i purchased a 1995 UKDM with the M2F5 box.

Questions: Can this box be upgraded with an lsd?
Will i need a JDM manual ecu?
Any easy to follow user guides for doing this?

Cheers

1. Unfortunately, don't think so.
2. No, you can convert the Auto one.
3. There are a few on american sites, but in all honesty, there's not that much to it.

Merlin has an M2F5 gearbox with MFactory 4.64 final drive and Kaaz 1.5 way LSD

I'm assuming he meant an OEM LSD, the Kaaz is not really practical for road use.

Yes I do

but not in my road Prelude. Yeah you can get an aftermarket or ATR diff to fit the M2F5. But as Vtecmec says the best info for auto-manual will be on US sites. Although Salazar was pretty good at describing his swap. Have a rummage round his thread from PUK days http://preludeuk.forumup.com/viewtopic.php?t=23834

Cheers guys, I thought i red somewhere that some people install a quaif lsd in non lsd boxes?

But to save hassel i would prefer just to bolt on the M2b4.

For £350 i got a donor car will all the parts so was a no brainer.

Pssh! It will be fine once he gets used to it

PreludeUK isn't working, i remember there was a write up on how to do the swap but i can't get on the site.
