Brian,
There are a few S2000 powered TRs around along with the M3 powered TR6 previously mentioned. I’ve been studying the M3-Getrag swap and have several generic pieces including a TR6 frame for the TR4a, but after visiting with some very knowledgeable people who build cars/restomods for a living I’m leaning toward the Lexus/Toyota engine with the 2JZ-GE or 2JZ-GTE and Getrag 5 speed. Besides being cheaper, more plentiful, easier to fit and modify, and more HP and torque than the M3, I have someone who will help me who’s done this work before. This is one of the reasons I’m a proponent of a Triumph Performance Forum.

Looks like the battery tray area has been modified a few inches.

Brian,
I was looking at that picture and I googled the dimensions of both the TR6 and 2JZ engines. The 2JZ-GE is an iron block, aluminum head and weighs 507# vs about 400# for the TR motor. The 2JZ is 31” long from the fan to the flywheel and the TR is 32” long, the 2JZ is 27” tall from the bottom of the oil pan to the top of the cam covers, the TR is 25” tall. If any of these rounded off numbers are wrong, please let me know. It looks like the 2JZ is about 100# heavier with the tranny vs the TR motor and tranny, so higher rate springs might be in order.
Thanks, Rut

Brian,
I sold a 76 TR6 last year with a 280Z Datsun engine and five speed. It was converted by local mechanic. It was a decent job. Had fuel injection. I bought it later when it was it wasn 't running and put early 240 carbs on it. Due to the height of engine, the hood had to be bumped out in the front about two inches and the battery tray cut about two inches. I first bought it to return it to its original configuration but it ran so well I left it alone.

Anyone remember that old ad "I coulda had a V8!" ?

There are a few that are actually lighter than the stock lump. Eg,

I just happen to have one of these in the garage - a brand new factory fresh ATK remanufactured 2.3L inter-cooled turbo long block originally purchased for a 1987 Thunderbird Turbo-coupe. . The "tuned" 400HP one below is in a TR6 but I'm sure mine would fit just as well in my TR4 with "just a few small modifications". Straight stock it is an instant 190 HP with 300 HP easily within reach. Plus it comes with a nice factory matched Borg Warner T5 5 speed OD transmission. Every time I look at it I am been tempted and have to remind myself I did not set out to build a hot rod / race car and the added dollar cost is a waste of money for a street TR. On the other hand it wouldn't be a LOT more money than rebuilding the stock engine/trans/OD and it would certainly get attention and turn heads with the modified bonnet up or down spinning smiley sticking its tongue out

Get thee behind me Satan.....

There a a lot in the gallery at BritishV8
For the Ford 2.3, look at Dale Knapke's car. Calvin Grannis' LS1 conversion is pretty awesome. Ted Lathrop's Chevy V8 is too. These guys are having a lot of fun!
