R5GTL//R5TS-motors..Top-end same???

[reidalpine]

Gang! might have asked this b4 incase hope you'll bear over with me...

-I need to know if the bolt-pattern for fixing the inlet- and outlet-manifolds are the same on the R5GTL 1289cc. and the R5TS (I'm talking MkI) are identical ???
-If so,were the only difference between these "wilder"cam and poss.larger
valves (intake and/or exhaust)on the TS? + Higher comp.possibly?

Main thing I need to know asap is if bolt-pattern is same! Thnx Much/-R.

I am very sure that the bolt pattern is the same!

I have both a R5 GTL and a R5 TS engine stored at the back of my shed, as well as a TS engine in my R5 Race Car.

Like you say, the cam is wilder in the TS, but I think the valve sizes are the same?

Thanx much Hannu-I think you are correct.I have done some more research and found it to be identical too,so now it's GO.. new headers (double Y) reworked alu-intakemanifold and double 32/32 Weber to go with it.Also new sporty muffler -BROUMMMM.... -R.
