After moving to NY from Colorado (yes, I'm doing it bass ackwards) I've finally decided to give some love to my '75 TR6; my ten-year old purchase made possible thanks to EBay and Sam Adams. It's in pretty decent shape and I've had some work done on it by a local shop to get it in good driving order. Shop's link below for anyone who cares:

I read the Classic Motorsports article originally from 2007 which upgraded a 1975 TR6, and decided that would be a great path to go down. I'm hoping to gain some knowledge, insights and opinions on carrying out similar mods. I drive the car around our little town with my seven year old, who loves riding in the Sports Car! My goal is to recover some of the horsepower and then some while maintaining a pleasant drivability. While I'm fairly mechanically inclined, the TR6 is shoehorned into a modest two-car garage alongside a couple of Ducatis, seven Razor scooters and a few Treks, so my in-house maintenance capability is fairly limited. I'll be having much of the "heavy" engine work done at my shop.
I'm submitting several questions for your input.
- I'm thinking of switching to SU carburetors available at Moss (recommended by our local shop). The article used Webers, but I've heard that they could be labor intensive as far as maintaining. Thoughts? Sidedraft vs downdraft - what are advantages-disadvantages?
- Any experience with installing a cam? The article mentioned a GP2 cam from Goodparts. Opinions on this?
- Thoughts on porting and shaving the cylinder head? The article stated shaving the head would increase compression. Any ramifications I should consider?
- Ideas/recommendations on headers for the car? Will they provide additional benefit, given the above items I wish to have done?
- Is there a preferred choice for upgrading the distributor to electronic?
I don't want to go crazy with mods, as much of the work will be done in the shop ($$$), but at this point, the above upgrades are where I'd like to go. I would greatly appreciate everyone's input on the above.
Regards,
Jack
