SidewaysNolo

Hey everyone, new to Zilvia and fairly new to s-chassis in general, so excuse my lack of knowledge.. but have a few questions concerning my build...

Basically i picked up an s14 that was already sr-swapped, and the car is very clean for a canadian car. Hardly any rust, chassis is great, everything feels tight. However it feels slow. Sluggish taking off, sluggish through boost.. It almost feels as though its not getting enough fuel or that the car is being choked. Ive done all new boost lines, and FMI couplers, as well as checked all of my BOV and wastegate connections.. Thought it was boost leaks and after i did the couplers and lines it fixed the problem marginally, but it still feels slow. Ive heard it may be a fuel pump/FPR issue? ive compression tested the car and its 155s across all 4 cylinders, with 1 cylinder at 160. Ive driven a few other stock Srs running on stock boost like mine and they pull much harder and have better throttle response. I actually drove at shannonville for drift day a few weeks ago and the car bogged so much that it wouldnt even maintain tire spin in second gear. Couldnt gather enough revs it seemed. Basically the power was not there.

Im going to keep looking to try and find other solutions but any help or advice would be greatly appreciated.
