rev problems

[ozcustoms]

i have already posted this but not in this forom. this looks like were it needs to be. also since then a have taken down mas and cleaned it, but it didnt help.

i have a 90 talon tsi.when i bought it would only rev to about 4500 rpms .after that the hole car starts jerking something like it hit a rev limiter. i checked the compestion it was bad so i have completely rebuilt motor. new piston's and rods, crank, cams, springs, valves, 2g exhaust man. new intake, new manufacture o2 senor, and new knock sensor. put it all back together and same problem. since then i have tested computer witch is out of a 90 turbo fwd(i was told as long as it for a turbo it shouldn't be a problem) it has new compasiters so it should be good. i tested the isc good i think.i put a egr block off plate. it doesn't have any emission, was like that when i bought it. i also put a new walbro fuel pump on it. i was driving the car one day trying to see if anything i had done helped. i made it about a mile and broke my stock turbo. when i say broke i mean, i took it off and it came in pieces. so i bought a 16g for it put it on still the same problem. i have also tested the coil good. and all plugs and wires are new.

this is a post i wrote on another site. since then i have changed the ecu and same problem. it will actually rev to about 4500 in first every gear after that is between 3800 and 4000. i have know idea what to do next. will tr
y anything.
