I did a swap on a 94ls to a b20 block w/Type R head +all the internals w/p28 skunk2 chipped ecu, with Obd1 setup.
The block was new from the dealer (1 mile on it), as for the head with under 10k.
When I test drove the car it ran normal, but then when I went to test the power It lacked BIG TIME, at lower revs it picks up speed normal (1500-3000) , but after that I could slam it to 8,500 rpm and the speed will pick up so slow?? AND I MEAN SLOW (btw my rpm's not working)
Compression is straight across the board
Not sure what it is, Im going to try some new injectors, the old ones were out of a gsr.....

Please any suggestions would help
