I have a 97 GS-T with a fresh full rebuild. The car has 502 miles and runs great except at idle. My idle is very eratic and usually elevated.I have a P0505 code as well as a P0325 (knock sensor malfunction). Knock sensor and IAC valve are both brand new and I have also tried other sensors in...

I recently got my car running after a full engine rebuild. AEM AFR gauge will read 14.5-15.5 ish on initial start up but the car will begin to raise idle speed to around 2k on its own after a few seconds. When this happens the AFR gauge pegs out and reads three flat bars (over 19:1). I can...

Does anyone know where I can get a fuel pressure solenoid (K5T43988)? I am under the impression that without it your car will throw a CEL and I live somewhere that requires emissions, so I have to at least have it plugged in. My car did not have one when I bought it and I am almost done...

I recently got my block back from the machinist and they removed the oil plug on the transmission side of the block. Does anyone know what thread plug I need to replace it? Thanks.

So this probably seems like a reaaaaallllllyyyyy stupid question but ARP hardware is expensive and I dont wanna F this up. I am getting ready to check my oil clearances for main and rod bearings and I am wondering if I should use the new ARP hardware that will be going in the car when I torque...

I have a 1G FWD manual trans that I purchased in the beginning of my build and didn't do any research on it (like a newb). I was told it was a 2G and took the guy at his word. I can't use it and don't really know the history of it so I don't want to ask much for it. It does have one axle. Throw...

I recently got my 7 bolt back from a shop that was supposed to be building with basically no work being done. The engine is completely torn down and the block has been inspected and measured. I have decided to complete the build myself as I feel confident that I can do it, plus it's time to take...

I did a bunch of research on this and wasn't able to find a definitive answer so I figured I would post in case anyone else wanted to do this. I have looked high and low and could not find a decent set of 2G sun visors for my car. I tried opening mine up to recover them and absolutely demolished...

97 GS-T. I have been unf*@$ing all of the wiring on my car that I discovered when I tore everything down. I have everything figured out so far except these two wires hanging down under the steering column. The colors are yellow with blue strip and white with blue stripe. They attach to a harness...

I have a 4G63 valve cover for sale. It's an extra so I don't need it. Asking $170 plus shipping and pp.

Alright guys, I really need some guidance here. When I purchased my car, unbenounced to me, it had at Evo 8 engine block with a 2G DSM head. The bearings are shot and a lot of the work was half assed so I am rebuilding. Where I am running into a problem is finding good info on whether this combo...

I recently purchased a used small 16G turbo and am overall pleased with my purchase. The question I have is that the compressor wheel and inside the compressor housing there is some rust. I am wanting to know if this is something I can clean myself with something like brake cleaner and some...

I recently removed the engine from my 97 GST and cannot seem to find an answer to my peculiar pulley setup. I am aware that the standard 4G63 setup has three belts. My car has A/C and PS deleted so I would only then have one belt going around the alternator, crank, and the water pump. Well...

I recently purchased my 97 GST and am in the process of sorting out the rats nest of a wiring job that the car currently has. I discovered a wire in very poor condition that broke off of what appears to be a knock sensor. The problem (and question) is that the sensor screws into the block...

I have done an absolute ton of research and I am hoping someone here can answer this for me. Every photo, reference, video, and diagram I see of every possible option of oil filter housing for the 4G63 shows the oil filter in front of the block on it's side. Mine sits vertically on the pulley...
