Alright, so my 95 S14 has been giving me nothing but trouble and it is giving me two major issues (insert breakdown here ).

Issue #1 - It just doesn't want to put the power down. I step on it and it doesn't give me really any throttle response past 2000ish RPM (that's in 1st. Every other gear is just noise, pretty much. Sounds like it should be accelerating rapidly but isn't.)

So I swapped in a different KA from a 93 S13 since the motor my car came with had a serious rod knock. The new one had 130k miles on it and ran well when the guy pulled it from his car (showed me a video of it). I did everything I needed to do to swap a S13 KA into a S14, gave it a new valve cover gasket and oil change and dropped it in. It sounded like it had a misfire so I gave it new NGK plugs and wires and that seemed to take care of that. The PO said he used to drift the car (on an open diff ) so I swapped that out for a welded and that didn't do much. I changed all the trans/diff fluids. I'm stumped on what to do next.

-I deleted the EGR, I'm not sure if that has anything to do with it?
-I also blew (and keep blowing) the 75A alternator fuse. I've checked and re-checked to see if everything is grounded but can't find the issue. Does this have anything to do with it?
-Could I possibly need a new head gasket? Throttle Position Sensor? Throttle body? Is something not sealing right?
-Maybe driveshaft for some reason? Axles?
-Could it just be bad gas? Fuel filter? Injectors maybe? I put a gallon or two of premium in it back in late January just so it could be started/run every couple of days while I'm away at school.
I have no idea.

Issue #2 is the 75A fuse. Pretty much the only electronics that work on the car are the headlights, and this is the only fuse I found blown. No tail lights, turn signals, brake lights, power windows, power mirrors, tach, rev counter, temperature gauge, radio, nothing. I disconnect the battery, put a new fuse in, and as soon as i reconnect the battery it blows again.

-Could this affect the previous issue as well?
-It's obviously the alternator fuse, but what's most likely to cause it to blow? Not grounded right? Bad alternator? What?

I've done all the obvious stuff I can think of but after 3-4 weekends of this, this is really starting to piss me off. I'd like to know the most obvious next steps in order but any help/insight is appreciated.
