I have attempted to find this info without really getting a confident answer. However, I can only assume it is due to a supersession, but my part catalog does not show this.In the photos you will see two 5th gear assemblies next to each other. The one of the left came out of a 1993 GSX AWD...

In the photo you will see the intermediate shaft assembly sits slightly higher than the input shaft assembly in the case. I believe this is causing too much clearance between the input shaft bearing race and the case which doesn't crush the solder at all when assembled. I did replace both top...

So after a test pull on the street @ 26-30 Psi to 7000 RPM 43db knock (Haltech elite) on 93 I noticed evidence of coolant on the transfer pipe which looks to be coming from the water/pump o-ring to pipe connection. (See photo). I’m not sure if I should be concerned about this, but I kinda am...

Something’s doesn’t seem right with this MAP scale in Haltech. Can anyone tell me if this is correct. I have attached a photo. It is an OMNI 4 BAR….I mean 4 bar =58 PSI so I’m just checking to verify if this scale is wrong. Also I’m questioning the vacuum scale as well Thanks

Hello,Went to install my S90 and start my car today and realized the throttle stop screw on the side of the S90 T-body is all the way out. I bought it used so Im not sure what was done to it. However, does anyone have any idea where to adjust this throttle blade to? I have search everywhere...

Hi, seriously is this the clearance that Precision built their turbos at the oil drain adapter? If it isn’t clocked enough the compressor housing will hit the -10 fitting “the bolt that is”??? This is a PTE oil drain adapter for -10an Is this the way it is with these turbos?Also anyone use...

just trying to research necessary vacuum line sizes when using -AN fittings. I’m running two Tial waste gates and Tial BOV with JMF race intake, Omni MAP, FPR, brake booster, etc. I want to keep the aesthetics of the build so I want to go with -AN hose fittings and hose, but having sleepless...

Hello,My head is spinning reading all of the threads trying to figure out what I need to do to install a 92 shifter base (inside the car) onto a 1990 DSM with a 1990 trans and cables?I am questioning this because I heard the 91-94 shifter base assemblies have a shorter throw. Well I guess I...

I'm looking to purchase some 1G mud flaps if anyone has these rare diamonds available?Also, does anyone know the factory part numbers for these things? I guess I would prefer Talon, but beggars can't be choosers.

I have been noticing knock when driving around and sometime enough to pass the 5 degree threshold that flashes the MIL at you.Im just wondering in the log I have attached if this is something to worry about? I notice that most of the knock occurs during low RPM tip in. However, I'm not 100%...

Just checking to see if the fitment of these RTM rear subframe bushings is acceptable? The inner sleeve is still present in the subframe, but a little worn out.In the video you can see that they drop right in by hand, but there is to no play. However, if the subframe was tipped over they...

anyone selling a 4 port closed loop Calan Catch Can?

Looking at the valve cover baffle area design of the valve cover after removing the factory baffle has me thinking, if I use the PCV valve with -10an fittings at the rear of the valve cover if vacuum is just going to pull from the -10 line right next to it and whatever is in my catch can? I will...

Hello,I recently rebuilt my transfer case from parts of spare t-cases layin around. I replaced the drive gear preload taper roller bearing ( this is the bearing on the input spline side of the case). This is the only bearing I replaced and was sourced from Autozone since I could not find the...

Hello,Recently I started and ran my freshly rebuilt engine that was put together 17 years ago...yes, 17 years ago i had it bored and installed JE pistons (8.5:1) and crower rods, etc. Back then all I did was assemble the complete long block and monthly poured oil down the cylinder and rotated...

HI, I am trying to isolate this weird oscillating metallic chattering noise coming from the bell housing area @ 2800-3000 RPM.When driving and accelerating the noise comes in steady at 2800-3500 RPM and then goes away,. Noise is pretty much only occurring in that RPM range.I have noticed...

Does anyone know the factory alternator pulley size for 1G Manual turbo (US)?Does the Canadian alternator (90A) have a different size pulley? I say Canadian 90A because in the factory service manual it states the 90A is for Canadian auto 1G'sI ordered an new Denso alternator (90A) from rock...

Does anyone have a final remedy to address the oil leak from the lower timing belt tensioner bolt on a 6 bolt? (photo attached)I have read post, but wanted to get a fresh suggestion as most post are from early 2000'sI have used 3 bond on the bolt, but obviously it still leaks.Also is there...

hello, I have read through a lot of post about idle surge, but my test are not bringing me to isolate the cause.This is the first time this engine has ran after a full rebuild. The CAMs are: Intake 264 and Exh 272 HKS.The ECM is 92 AWD 4G63T (stock)The IAC is new (replaced) and the TPS...

Im in the process of purchasing a complete MeganRacing 3" exhaust for my 1G, but I was just wondering if anyone could assist me in identifying the pieces in the attached photo. It shows 5 pieces.The down pipe, the resonator, the CAT back pipe and muffler. The pipe in the photo I am confused...

I can't get oil pressure to build or reach the lifters during cranking ( have not started engine yet). I just installed the remote mounted AEM oil pressure sender with SS line. Has anyone ran into not getting oil pressure to build during cranking? i almost smoked my starter trying for so long...

Would like to know if it will cause any damage to the ECU if the MPI relay is eliminated and switched B+ is ran to pin 107 (C-59) of the ECM?I would also be eliminating all factory fuel pump control circuits (pins 56, 13, and 108 at the ECM) as I would run a HP pump on a separate replay and...

Does anyone know if the reed switch input to the ECM has any major impact on engine management? i.e. idle, ignition timing, fuel control, poor performance, etc. ? I am contemplating if I need to wire it in or not.I am working with a stock ECM set up attempting to wear in my motor. However, the...

Are the 92, 93 and 94 CAS output signals the same?I need to use a 93/94 CAS with a 92 ECU.All I know about the CAS sensor I am using is that it has the black plastic cap, but not 100% sure which MY it is out of.Thank you for the info.

When installing the timing belt with the Kiggly racing tone wheel and AEM cam gears I have lined up the marks on the cam gears and held them in place with the STM cam gear holder. I have lined up the mark on the tone wheel (crank gear/kiggly tone wheel) as accurately as possible (the balance...

hello, I have a 93 GSX 67,000 miles, it is stock except for an old HKS vein pressure controller (SD) system. When the car is cold soaked the idle surges bad and almost stalls. However, when the engine warms up the surge disappears and everything is normal. The first thing I did was remove the...

Is it common to use a 2G CAS on a 1G 6 bolt (90 TSI)? When ordering the Haltech 4G63 terminated harness they can custom fab it for a 2G CAS for a 1G engine. Has anyone installed the Kiggly Racing CKP kit for a 1G using the Haltech terminated harness with the Elite 1500, is there anything in...

Has anyone installed the Kiggly racing 12 tooth crank sensor kit on a 6 bolt 1G and has oil leaking from behind the flat head allen bolt that secures the sensor mount to the front case?I have used teflon tape and Mitsu 3 bond, but seems to still seep a little. Before installing this kit i had...

Would this be a recommended place to tap in for an oil pressure gauge?

what is recommended for oil pressure monitoring? tapping in on the filter housing somewhere and running a line in the vehicle? If so, where would be the best place to tap in? at the sender? or using the stocking sending unit and using a electronic gauge?
