A client approached Schraders Speed & Style in Azusa, California to swap a LS1 into their 1969 Triumph TR6. After measuring the engine bay Schraders recommended the client go in a different direction and use a RB25DET from a Nissan Skyline R33.
Besides the RB25 being a better fit, the engine choice kept more in the “spirit” of the original Triumph engine also being an inline-six with a similar displacement. The power was greatly increased as well. The engine running on 10 psi of boost produced an estimated 380 horsepower.
Even though the engine made for a better fit, it still required a lot of modification to work. The steering rack was moved and the steering column and firewall was modified to clear the turbocharger. Schrader also had to make custom turbo piping, intercooler, and radiator to fit inside the small engine bay.
The limited slip diff was sourced from a Infiniti Q45 and used custom adapters to fit the halfshafts. The front suspension was updated with new lowering springs, new shocks, larger disc brakes with Toyota calipers. The rear suspension was upgraded to coil overs with Nissan 300ZX discs and Wilwood calipers.
The project took about three years (2006-2009) and $95,000+ to be completed. The car is currently up for sale with an asking price of $45K out of Pasadena, California.

Have plans for a small block in a TR6. Please keep me informed with articles. Thaks, tony
Hi Anthony,
This is the owner of this TR6. The reason I own this is because I did a V8 conversation to a TR4 when young and didn’t have money to do a better job and wondering what if I had more money to own a better one. But I learn few negatives about doing a V8. Welcome to contact me if it helps. PJEE@Sbcglobal.net
while this is a gorgeous looking install, it seems that the SVO turbo Ford is a MUCH easier swap. Only ONE simple sheet metal cut and weld is apparently needed. That is on the right inner fender.
Done a V8 conversation at early age with lack of money and knowledge. But discovered few negatives and wondering what it will be like to have one that’s done with better money . Now the car is still for sale and it’s more refined.
Phil, I put a rad, motor and transmission out of my brothers ’66 Vette into my ’69 TR-6. Wish I had it back. It is somewhere in Calif. Awesome car!! BOB from Ill.
Consider an SVO turbo 4 from a ’80’s Mustang/Thunderbird. They can be easily gotten to 300 hp without making them unpleasant for touring. There are now two of them that I know of. Mine is one. The other is supposedly producing 300+ hp but the hood had to be modified. I’m not sure why. The guy who built my car didn’t have to do that at all. The only sheet metal cut and welded was on the front inner fender. It is easy for someone not in the know, to miss it.
