Hello everyone,
Could you give me differents between TLS and TLR engine?

 

[Birdy]

And is there an engine number that shows the different power engines on the tls?

 

[The Ring-In]

all D port engines have numbers cast into the bottom of the inlet tract.

run your fingers under the throttle bodies and if there are numbers cast in the ali its a D port head.

early 97's had round ports and no cast in numbers

OK, but what about differents in construction between these engines?
Are they basic the same engines but with different throttles, injectors, maps, airbox, exhaust system?
And I know that one has oil radiator.
What about gearbox?

R's have forged pistons with higher compression, and different cams......IIRC
Early S's had 5 bolt clutches....all R's have 6 bolt.

Thanks mate. This is the answer what I want to heard.


I heard as well that engine case I R version was better for bearings but I'm not sure about this information.

Early S models don't have the grooved journals that the later models and the R have.

Yes, I think that you are right. There is something about the output shaft bearing. I don't recall exactly what. I think the diameter is different?

There are plenty more out there, but these two threads have some good reading for you.
