MGB TR7 5 speed in MGB

Will a TR7 5 Speed transmission bolt up to an MGB 1800 block?

Any other issues if it does?

I don't think so....not without some changes to the backing plate, input shaft, etc.

Take a look at the Riverside (Datsun) conversions or the T9 conversions already available. The work has been done for you.

Let's not forget that Hap (speedracer) is offering a kit of his own. Using the
T5 transmission and the like. I think his prices are better than the rivergate prices. Hap has the kit listed on his site www.acmespeedshop.com.

Something to think about anyway.

$3000 would bust my budget..

I've thought about this one, as the Austin Marina used the 4-speed that came on earlier TR7's and the Marina used an 1800 as well. So, some permutation of bellhousing/gearbox from the two models may make a working setup.

which brings me to my question. the 1500 Midget transmission is also adapted from the Austin Marina. George Turnbull left British Leyland and went to Korea with 2 marinas and developed the Hyundai Pony. ( https://en.wikipedia.org/wiki/George_Turnbull_(autoindustry_executive) )I don't think the Pony ever entered the USA but it did Canada - which makes me wonder how compatible its 5 speed might be

I ***believe*** Hap is using the T9...not the T5.

The Pony started dissolving on the boat ride over. You'd be luck to find on still on the road.
