General Car Chat / Re: Fitting a Y32SE to a 1972 scimitar GTE.

Yes, there's been two that I know of, but they remained road cars. I'm the only one that wants to put the reult on a track, so having a few conundrums re clutch and gearbox. Is the r25-R28 any good. Any has anyone done the SMF conversion on a petrol car ?

General Car Chat / Fitting a Y32SE to a 1972 scimitar GTE.

Hi, newbie here. 
I have a 1972 scimitar GTE that I sprint & hillclimb and its my everyday roadcar.  I keep destroying the Ford Essex engines and Type 5 / 9 gearboxes despite being upgraded, so for more power / reliability I'm fitting a Y32SE from a police car. It has an R25-R28 gearbox.

I'm in a dilemma re the clutch. The existing dual mass flywheel has a 240mm plate that looks pretty tired. I'm loath to replace all the DMF, as I'm not sure it will cope with track use, so I'm thinking of either

1) converting to SMF and keeping the R25-R28 box.
2) converting to a RX8 gearbox. Parts are available.

So for either option I need to source an early SMF flywheel but then its only a 228mm clutch whereas the omega is 240.  But I've also heard the R25-28 box is not that strong and I should go for R30 ??

So just a tad confused...

Any ideas
