It is two mufflers that are bridged together and the "Y" is built into them. All that is needed is to adapt the single pipe to it. No additional Y is needed.

In reply to # 1497830 by rpierce looks great. is that a single unit that splits from one pipe to the two muffler tips?

In reply to # 1497721 by trrdster Russel, you mean something like these. Took a while to fine them.
I'm going with gun metal gray, not sure which one, like the BMW and the Mazda one.

I would LOVE to have one of those triple intakes.
Jealousy is a terrible color, but it's all I got right now.



If it's not leaking, it's empty.

LMAO! It's OK Flipper. Stay calm. Email me if you want some reality on the triples. Don't get me wrong - I LOVE them, but maybe not for the usual reasons.

Based on the technical bulletins from Triumph, you should have an 8.7 gal (US) tank as shown in this cut from the book. That is about 7.2 imperial.

Jeez, ... I'm really happy I found an old, non-EPA choked tank for Roci. The thought of running a modified GT6 engine out of 10 gallon tank was scary enough. To have 8.5 (or LESS) would have been unthinkable.

Was a rough estimate Dan. Might be off by a gallon. I'll have a more precise measurement when I fill her up.

Some gas stations are known to cheat the pumps to make it look like you are getting more gas than you really are.

Just curious Dave, what led/leads you to believe it might only be 7.5 gal?

I've often thought I might have a 7.5 too. Filling from running on vapours to almost out the spout has never taken more than 7.5 gal (pump reading) in my car. I did once run it til it ran completely dry and cut out... My gauge packed up that week and I thought I could make it to the cheaper gas station a little further away eye rolling smiley Even that time it barely took 8 gal.

But logic tells me that a 1980 Spit 1500 with emissions equipment would have 10 gal. Unless a PO did something seriously dim when replacing a perforated tank.

Jim -

Richard Good at Goodparts makes the Mk1 Manifold. While he mostly makes TR6 parts, there are some that he will adapt for the GT6.

Be careful with the 3x Z/S manifold - While the one from the Vitesse/Triumph 2000 and the GT6 Mk1 manifold looks the same externally, the GT6 intake ports are almost 1/8" larger in diameter (see photo). If you ever want it, send him a the gasket and he will machine it to port-match.

To be honest, when I went from 2 to 3 carbs, getting the whole thing tuned (and getting it to stay that way) was almost impossible. After a year of tinkering, I saved up the money for the Patton Machine 3x throttle body fuel injection kit with mapped electronic ignition. While costly ($2,500 for the kit), that changed the car from a weekend project to my daily driver. If I did it all over again, I would have done both projects at the same time, but I did not have the money.

Richard Good will also makes 4-piston Wilwood brake upgrade kits for the fronts of the GT6 - although this is more complex. His calipers for the TR6 will fit, but, you need to have him mill the Wilwood 10.5" rotors down to 10.25". The bigger issue is that the new calipers are taller and the stock wire rims that came with the car will not fit. Since I wanted to go from 13" to 14" rims anyway (for more tire options) - that 1" gave me the space I needed for the calipers to fit.

Be well

Jack

What the hey!, Jim. I thought you were getting 30 mpg..........sounds like you are getting more like 15!!! Keep your foot off the accelerator some. I know, I know, that is hard to do with a Spit6. hot smiley
