Sport 3 port - You can use a turbo button off of a 5 or 7port. Race 3 port - I think comes with a turbo. |
guys thanks shane keller saves the day question answered ...thanks shano:D

The sport 3 port will run very good with a turbo head button, the sport engine has more bottom than the spec 3 but it doesnt have near the top, the spec 3 is turbo only, the spec 3 is also easier to control out of the turns, very fast engine., i have 2 available

Had the same problem with mine mate.
To fix this pull the retaining screw out, then the two halfs of the locking bolt that clamps the carbi in the crankcase then grab an angle grinder and shave a small amount off the midle of both of the pinch bolts, dont bother trying to do it with a file as it is hardened steel and you will be there for a year, or use a pedestal bench grinder just be carefull, and i promise you this will fix your problem, just dont forget to seal the pinch bolts after and lock tight the retaining bolt when you line the carbi back up. hey gen how much did you take off in like millimeters? thanks man |

Hi guys, I know there has been a lot of talk about what pipes to use with what engines, I didn't pay too much attention at the time because my 7 port turbo was running real good with a .053. As of last week it seemed to start changing on me. Wasn't running very good at all. I checked the usual things like fuel line, glow plugs, clutch etc. Everything checked out. Decided to try just for kicks to change the pipe to a JP-1 and seems to run really well with it. Won't know for sure until I get it on the track, but ran well up and down the street with just a slight difference in tunning from my .053. I still have the head shim installed. The engine is fully broken in now. What effect will keeping the shim in versus taking the shim out have on the engine?
Does anyone else have an opinion on using a JP-1 pipe on the 7 port T? For that matter, what about the other JP pipes? |
Taking out a shim will give you more bottom end. My son was running a Nova 9901 on his 7 port last time out, haven't played around with many pipes yet though.

well i figured out my lean bog issue it was a carb leaking at the base where it seals to the engine so i ripped it down sealed everything and installed my turbo head button with a os p3 plug and so far so good i ran a tank and it temped around 200 with plenty of smoke and power and no lean bog

I have drive my 7 p 2 gallon, and i have not take out any shims, i think is 2 shims ther, shold i tak out 1 shim?
