I was wondering why you chose to go all the way around with the hot coolant pipe from the right head's heating exit at the back of the engine??
Is there an advantage in that and what did you do with the front hot pipe from the w.pump?

Sorry, I missed to answer this question so long.

On the GTA engine it goes back as well, so there are 2 tubes running around the engine. I never thought it could cause any problem. There is the termostat-housing so I just designed the pipes to run to the cooler.
The advantage that it can be maintained with standard parts from catalogue!

Anybody has idea what kind of cams could be used on the GTA-engine to get some extra HPs? And what is the cost of it?

What I can do:

- can add more fuel
- can reprogram freely the ECU

What I have to live with:

- I won't want to rev over 7500 (so I think it would be great to have the peak somewhere around 7200)
- The engine is a stock unit no lightening at all

Or just ask the SA Team with the specs?

At what rpm does the GTA ECUs rev limiter cuts?

Hi Chen!

We can set the revlimiter where we want (now at 7500 and since the rest of the engine has not been touched I don't want to raise above it). The original Motronic finish somewhere between 6700-7000, but the peak power happens at 6200.
