Hey guys im doing a 6 bolt swap but ran into some problems :( im so lost and so desperate right now please help!!!!

instead of going with the 1g intake manifold i got a Magnus SMIM+bbk75mm TB. The swap is a full 6 bolt head+block i also got the RRE 1gina2g wire harness. the TPS is not connected up as the bbk plug wont fit into any plug from my engine bay.

Do i need to have the tps connected for the car to start?

Does my MAP sensor need to be connected for the car to start?

I have fuel, spark, compression timing is proper but the car backfires very loud and sometimes spits through the intake mani? i thought with bad timing it would do that but im sure we fixed the timing 2night it backfires through the exhaust


Im very lost at this now dont know where to start ive replaced a starter today with hopes that my problems would be fixed but still nothing. sigh hope i didnt leave vital info out sorry i did search also please help as best you can ive read as much as i could ill update as i go along. Thank you!
