Alan,
That would be great.
I can't imagine what is wrong with my setup.
In order for me to get the 25-30mm space between the end of the turbine exhaust cone and the point where the bellmouth meets the ss thrust tube the engine for some reason is further back from where Dave W recomends the front of the turbine to be. This is with the thrust tube extending out the rear of the fuse 3-5mm.
The engine I am using is the 140RX which I believe is the same length as the 120sx.
Because of all this the carbon deflector in order for it's mounting ears to lay under the jetcat mount has to be further towards the rear not allowing the front end of the bellmouth to lay in the grove at the end of the carbon deflector by at least an inch.
I hope I have made myself clear on the issue.
I always end up with some strange issue's in my build[

Thanks for your input,
Stan
