Ok this is for people who KNOW sr20det's.
Ok so a little back history, I picked up a new transmission from G dimension today and installed a new fandaza flywheel, new excedy clutch, and the new transmission, due to the other one frying and going out, and the only wire that is connected from the trans to anything is the speed cable, also install was done by a local shop,.

Ok so now the problem, so when I get about half or more pedel or to a certen speed in 1st and 2nd gear it will cut out, feels like im hitting a rev limiter even tho i dont have one. now i can floor it in 3rd,4th,and 5th no prob, and can rev at idle with no problem. Dose ANY ONE have any idea? thoughts ect?! please help.

I am going back to the shop tomorrow to see if we all cant fig it all out, i was just wanting to see if any one had any ideas???? let me know thanks

You should have 2 plugs from speed sensor and from reverse gear. Try to find it. Its in the middle right side of gearbox.

vacuum leak

whywould the rev limit be an issue? and if it was a vac leak, why would it only do it in only 1 and 2 gear?!

Do you have a rubber intake hose? Check that it isnt crimped or collapsing under heavy acceleration.
