Hi,

New user on the forum. I`ve had dozens of Opels before, but mainly older stuff like Kadett B, Admiral B, Senator B, etc.

Now I`ve started thinking about putting a Vauxhall/Opel V6 in one of my cars, the Reliant Scimitar SE4c Coupe. Since I am unfamiliar with the V6 engines and their fitments, I need to find out what 5/6 speed manual gear boxes can be used... Any tips?

PS... referring to motor codes and gear box codes will be counter productive, as I don`t know what cars have which. I learn quickly though :)

your best bet is an omega manual the r28 is supposed to be the strongest but there arent many about, well that i can find! There are loads of r25-28 manuals about but they arent as strong. Alternitavely you could use a ford type 9 or a borg warner t5 with a bellhousing depends on your budget.

with maybe some pics of your other cars... seems like you've got quite a nice selection...


and yes, omega B hardware = omega A (which is the carlton mk3 in England) hardware for the most part...
like suspension, steering, ...

Thanks for all input, this is all put on hold for a while due to unexpected car purchases... re the three Admirals. Old habits die hard! Might be in need of a straight 24V with a tranny though... Want it in the 72 Admiral 2.8E. Would be a nice everyday combination.

This is a good link that shows you what you need:

Opel-Infos.de

The stongest opel/vx gearboxes is from the omega with 3.0 or 3.2 v6 engines. They are called R28 or R30. They also have the correct flange pattern, older R28 gearboxes(from omega(carlton 24v) have a different pattern.

But if you want a really strong gearbox for rwd car, you should look for a BMW 328i or M3 5-speed transmission. With a welded flange change they work awsome. They can take 600-700 whp. A company i sweden sells them bolt on for 6500 SEK.
I have one in my omega with 700 whp/780nm.....

Its built by a swede...:rolleyes: c20xe block w/girdle, stock crank, SPM rods, JE pistons, ported head, bigger supertech valves, enem z42 cams, supertech springs, Precision sc6265 billett turbo, Autronic ecu. 700 whp/780nm at 2.9 bar boost. this is with E85 fuel.

Alf, you should build the Admiral with a straight six 24valve engine. Boost it and have fun:D
