Problems with swap Options

[celica3sgte]

My 2nd gen 3sgte swap into my 1994 celica st is complete. It was running great finally after receiving all the wrong parts for the clutch. Now it stalls once it warms up. I can keep it running by giving it gas. Even when driving it misfires every once in awhile and the rpms drop alot. Usually it misfires around 3000 rpms and it does it in all gears. Right before we stared having problems , we were messing around with vacuum lines for a boost gauge and we also hit the rev limiter to see where it was, Which is 7500(it thought it was 7300) Any thoughts?

here's a crappy site

Something occur to me just now.

Have you upgraded your fuel pump, holes and so on for fuel delivery?

Push a Fuel pressure regulator with a guage to see what PSI is coming through the line.

Please also check your Oxygen sensor, map or MAF sensor tosee if there are also good.

Please also check the other stuff I mention in my last post.

Please remember that replacing the engine, also need replacing other suff that need to keep the engine going like the fuel system.

Also check your wiring.

have a professional do it if you still continue to have problems.
