Just an update, 3 years later lmao.I finally got the car together. I'm close to starting it and getting it ready to drive. I end up getting my 90 AWD trans rebuilt, and just used the 22 spline output and t case. I have 3 extra lol. I plan to go auto after this trans blows up.Latest...

Does the noise change or go away when the clutch is depressed?

Yea just line up those marks and you should be golden. The above posted diagram shows it clearly.

You put a new new coil pack on? IF you are certain there is NO spark on 1 and 4, it seems like a coil issue. It's a waste spark system that fires 1&4, then 2&3 at the same time. both cylinders being out makes me believe a coil issue. But it is also possible there is something wrong with the coil...

Super legit!!

Looks pretty straight forward to me. Line up the position sensor marks, slide the housing in, insert CAS and bolt it in/I will admit, I've done alot of CAS sensor swaps on DSMs and that housing looks unfamiliar. Is this 2g a 98-99?

So here's the thing. THe BISS screw only adjusts the idle speed when you ground out a certain pin on the firewall or ISC connector, I can't remember. Or if you have DSMlink you can go into idle learn and then adjust your BISS. The ISC is always going to attempt to maintain target idle. so when...

Why would the Saturn alternator interfere with the A/C system? All you have to do it machine or grind down the alt mounting location and re wire the connector. you could be able to go that route and retain your A/C.

So you completely removed the power steering pump? Did you loop the lines on the rack, or?

When you boost leak test a car from the turbo, any intake valve that is open is going to allow those cylinders get pressurized. Even when piston rings are in good shape they allow some blow by into the crank case. That air is then escaping up through the oil drain backs in the head and out of...

I would upgrade valve springs while you are in there. You can rev out to 7500 no problem and really take advantage of that 20g and a cam upgrade.As far as the cam selection, there are more than one good choice. But Kelford 272s seem to work very well. Though something smaller like a GSC S1 or...

A shroud around the slim fan would help a lot. Also, if you are stock turbo, run all the heat sheilds you can in the engine bay, or even ceramic coat or heat wrap hot exhaust parts.223 is honestly normal operating temp. A little warmer than I like but its not hurting anything.Also, is the...

The trans is a 22 spline output shaft. I have a modified 23-spline '91-'96 t-case. I want to know if its possible to swap out the output shaft on the trans to a 23 spline so I can run this t-case...And also if the ratios are the same in the '90 trans as the '91-'96. Like aren't they all the...

Valvoline VR1, AMSoil dominator, Brad Penn and Joe Gibbs racing oil are the only brands I would use. As far as what weight to use depends on a few things: How cold it is, bearing clearances, piston-to-wall, and modified oiling systems. I like to run 10w30 in the winter & 15w50-20w50 in the...

So, options on building my '90 AWD trans. I hear 1g trans' are pretty stout when treated right. Seeing my power goals to be around 550whp, whats necessary to upgrade to handle that power level. Other thing... Is it possible to swap out the 22 spline output shaft for the t-case for a 23, and if...

Well if you feel like either pulling the motor or doing a little grunt work, delete the balance shafts, get some arp rod bolts, arp mains, and some new ACL race-series bearings. Have the cyl. head machined and even have new valves installed with a valve job/guid replacement wouldn't hurt. Check...

Like Kris stated. Make sure all of your plugs are gaped right, all the ignition wires are in good shape. You can try spraying down the ignition wires & coil with salt water in a dark room or at night with the car idling. If you see spark jumping anywhere; you have a problem. If that yields no...

I would do the timing belt & tensioners/pulleys. New waterpump, Also replace the balance shaft belt with a new OEM one. New plugs/wires if they look old or wore out. Take care of any oil leaks. New shifter bushings on the base and cables make a nice difference. Then start modding the vehicle...

^x2 on the Flyin'Miata mod to the steering rack. Fairly simple to do with the correct tools. Retains the power-rack turn radius from lock to lock. and is about as easy as the manual rack to turn when sitting still. Road feel is extremely good and you feel very in control with the car. Not to...

With the belt off, make sure the crank trigger lines up with its mark, and making sure cyl. 1 is on top dead center (TDC). Next make sure the camshaft dowels are both pointing up at 12o'clock. and the lined line up on the cam gears. If you have balance-shafts still turn the oil pump and hold it...

Bubbling? Try doing the boost leak test again and use a bottle of soapy water. spray all intercooler couplers, the intercooler itself, throttle body seals(be careful of getting electronics wet, they do not like water) Once you have found/fixed any leak. Then see how it idles and report back with...

When the oil pressure drops, do you hear any change it the engine sound? Like excessive chattering/clicking/ticking? If not it's most likely just your pressure sender or gauge cluster itself. Good luck!!

Sounds like its time for new front brake calipers. Wouldn't hurt to flush all the old brake fluid out and replace with new. Clean and lube all contact areas for slide pins and brake pad hardware.

What viscosity and brand of oil are you using? Also that idle is pretty low, I believe target idle is around 900RPM. Adjust your idle higher and i bet the oil pressure will be closer to spec at the target idle.

Sounds like syncros. but something obviously caused them to go bad.... how does the cluth feel? if its dragging you will ruin syncros.
