Tech Tips and Questions
 
Q. Engine swap question.
Have anyone of you guys out there ever considered putting a RX-7 engine into a GTX (1600) ? I just seized up my engine (got a little too eager with the boost pressure setting), and I'm considering swapping the engine for a RX-7 Turbo II or the latest Bi-turbo RX engine. If anyone has done this, please drop me a note. I would like to hear from anyone with remarks or suggestions on this swap.
Thanks a lot in advance.

Q. GTX Problems
Hey Reed,
I was wondering if you, or maybe one of your website visitors could help me out. I have an 1988 GTX with 115 000 KMs on the odometer. The problem I have is that when I floor the car in fifth gear, or near floor it, the turbo light blinks and a beeper sounds. This only happens in fifth, and not in any of the previous four gears. I was curious if anyone else has encountered this problem, and would be aware of the problem. Thanks a million, and keep up the great work on the page.
Contact: Brian Oldford, b.oldford@nf.sympatico.ca
Q. Problem with cracks in engine
I am currently experiencing trouble with a GTX 1600 Turbo that seems to have a crack in the cylinder block. The cylinder head has been off and pressure tested, and a new gasket fitted. But the problem is still there. Anyone out there who has experienced this before me?
The pressure in the cooling system is HIGH even when it is cold, and white smoke is coming out of the exhaust. Turbo is brand new. Looking forward to your mail.

Question on 323 GTX Wheelbearings
I am Dave Miller from Skaneateles, NY and have an '88 GTX, from new, with 87K on the clock. I love the car but recently have had trouble keeping wheelbearings in it. I have had two independent shops replace all four corners (about twice, it seems) since the first one went at about 65K. I have stayed away from the only dealer in Syracuse due to bad past experiences and would appreciate it if anyone in the group has some advice as to how to cure my problem. Thanks very much.

Eager Boost Cutoff
My '88 GTX has just been totally rebuilt from the ground up. The engine is stock other than a ported and polished head. Unfortunately I can't stay off the boost cutoff. I can hit the rev redline in first easily and the boost is about 8-9 psi, but when I shift to second, the boost takes about a tenth of a second to hit 11 psi and the cutoff if I stomp it. Each sucessive gear is the same thing. The only way to accelerate with this car is to use about 1/4 throttle and feather it just below the boost cutoff. Maybe this is normal, but I'm sure the car would be quicker WITHOUT the turbo. My mechanic says the wastegate is working, but I'm not too sure... suggestions?

High idle when warm
My GTX recently started idling at nearly 2000rpm when warm. I've got a factory maintenance manual and it seems to point to a faulty BAC valve but the price on one of those is over $500. I'm also getting a "Check Engine" light. Good news is that the engine is still there! Bad news is that I don't have one of those little thingy's to check the code in the computer - know how to do it the "other" way?
From: John A. Virnig, email <javirnig@aol.com>
A. Problem Solved!
I found the problem a short time after a person on your web page emailed me. Turns out the A/C button was depressed and while the A/C isn't working (insufficient Freon), the computer still bumps the idle.
 
Reading Diagnostic Codes
Here's how you get the codes from the computer without the Mazda diagnostic tool.
When you open your hood there is a pair of green connectors driver's side right back by the hood hinge. One is a six or eight pin connector, the other is a single pin. The eight pin works with the Mazda System 27 checker. That gives the codes directly to the checker, but you need the tool. The other single wire connector is the one that you want. It should be a female spade connector. All you do is shut the car off, open your hood, ground that connector (I have a male jumper for the connector and an alligator clip on the other end that I grab one of the strut mounting studs for grounding), hop back in the car and turn the ignition switch to on. In addition to seeing your oil light and your alternator light, you should see a check engine light on the top row. The light comes on steady for two or three seconds when you first turn the ignition switch on, but then will blink out the code that the computer has stored. Long blinks mean 10's and short blinks mean ones. Multiple codes are separated by a pause. The meaning of each of the codes is in the factory workshop manual, although you have to look a bit.

323 GTX tech questions
Hello, could you help me with 2 questions about our 323gtx's please?
1.Can you tell what that switch on the clutch pedal (at the top of the clutch arm)is, and what it does? It seems to prevent me from doing any type of fast shifting.
2.Twice while driving (making around 9-10lbs boost) I heard a horn type noise go off. Is this the factory boost cut off system? Do I need to bypass this to make MORE BOOST!?
Thank you, Ben in B.C.

What might make the engine race uncontrollably?
I have a 1988 323 GTX 1.6 L (stock) 92,000 mi., with a PFC-FCON, adjustable boost under the hood with exhaust turbo out, a reprogrammed ECU, and a dual-friction clutch pushing sixteen and a half pounds boost. I was racing it through first, second, and third gear, while slowing into fourth it revved to 8000 RPMs with out my foot on the gas in neutral. I turned the car off (took the key out), and it was still revving at the same RPM for approximately 15 to 30 seconds longer. I then put in fourth gear to kill the engine while at an almost complete stop. Towed the vehicle home and did a compression test with cylinder 1,3,4, with the normal compression and number two with about 60% compression of the others. Now there is oil in my turbo (which is a stock turbo). What I would like to know is what may be the cause of my engine racing like that and what could have happened to the car, and should I try to run it? I will appreciate all replies.
Contact:<Tecknovore@aol.com>
 
Shocks, or shocks, springs, bushings, swaybars?
I'm seeking performance information. My 1988 GTX has stock wheels, springs and suspension. It currently needs a new shock (it's leaking) and I am trying to decide whether to replace all 4 just to be safe, what to buy and whether to have the struts or any other suspension part changed at the same time.
The car has 90K miles on it and the suspension is all original. I plan to do mainly street driving but would like to increase handling as much as possible for as little money as possible.
I used to have an 1987 Civic SI with Tokiko Illumina 5 way adjustable shocks, stiffer rear springs, stiffer sway bars, 13x6 revolution wheels and 195x60x13 tires. This car was set up by Chuck Noonan of CRE Racing in Barry MA and it handled like a slot car on the road. I would like to get that type of handling out of the GTX but don't want to pay $3000 to do so.
Can you recommend a shock? Is it OK to stay with OEM Mazda or go with something like a Tokiko?
Given that the car is a lot stiffer than a stock 323 and the sway bars look really beefy and that I know a lot of people racing on springs with over 100,000 miles on them:
Would I get a significant increase in handling by going with aftermarket struts? What kind?
Would I get a significant increase in handling by going with aftermarket sway bars? What kind?
The bushings on the swaybars look worn, any suggestions on what to replace them with?
Can you point me to anyone in the Boston area that works on GTXs?

Q. Engine Trouble
I have a real stumper here and I'm hoping you can help me out! I own an '88 Mazda 323 GT which has one of those fancy 16 valve DOHC TURBO charged engines. It currently has 99,450 miles on it.
Last Sunday I washed the engine with a power washer. It hasn't been the same since. When I drove away I could hear sparking and could tell it was missing because of the water. I let it sit until the next day, when I noticed it was loosing power up around 4000 RPM. In fact it was taking so long to accelerate from 4000-5000 RPM that the Turbo Over boost warning came on! I continued to drive the car for a few days and the problem got worse and worse. It was so bad Wednesday night that I had to slip the clutch significantly just to get the car rolling. If I kept the engine below 3000 RPM it would decelerate even with it floored.
On Thursday I took it to my local shop. The found a crack in the distributor cap so we replaced it. Unfortunately that didn't do anything. After they checked all the obvious things I decided to try to get to work! I barely got on to the highway, but managed some how. When I got off the highway (30 miles later) the car was FINE, it had fixed it's self!! I was excited! Only to my dismay did I find the problem back Thursday evening when I got in to go home. The same thing happened on the ride home. After about 15 min on the highway it fixed it self and I had full power.
I took it to shop number 2 on Friday and left it there all day. He couldn't find anything wrong. He checked spark, timing, fuel pressure, air filter/intake, the exhaust system for a blockage and anything else he could think of. After a day of looking he called me and said I give up.
Monday I took it to the dealer and they did a wet compression check and said that the cylinders are supposed to have 154 but only have 100,90,80,104. They want me to authorize them to tear down the engine for $500.00 just to give me a diagnosis and estimate. What should I do? How could it be an intermittent problem and have low compression? Any advice would be much appreciated.
Thank you for your time. Jeff Banet

Thanks for the posting, it turned out to be the crank that was broken!! Read below, Brian knew right what it was! As it turned out, the dealer figured it out the same day Brian e-mailed me...

Subject: your 323 gtx problem
Jeff, First of all check the bottom pulley attatched to your crankshaft. Does it appear to wobble from side-to-side? It sounds like you have a broken keyway on your crankshaft. This accounts for the low compression readings and dismal performance. It is likely a coincidence that you pressure washed the car when you did. If you need help with a replacement crank or bottom end please write or call me. Project 323 is the world wide owners group for Mazda 323 enthusiasts. I have several used and 1 new bottom end around as well as ECUs, turbos (new & used) and always have a huge supply of parts on hand
Q. Normal Exhaust Temp?
What should the normal exhaust gas temperature range be on the 1988 B6 DOHC engine as measured at the exhaust manifold?
Thanks, Eric Rehwald, Jasper, AB, Canada
A. Around 1300 F
I have a 323 Gtx and I saw your question about the exhaust gas temp. on the turbo engine. I took out my catalytic convertor but I was seeing 1350 F on the interstate. Now I rarely get over 1300 but road race told me that these are normal temp's. If you get up around 1600 something is wrong. I try and let my car cool 1min~800 F, 2min~1000 F, 4in~>1200 F. Hope this helps some. Mike at road race is the expert.

Stumble off idle
I have a question for visitors to this site. My GTX has a bad stumble just off of idle. It is most noticeable when trying to hold a steady speed, like on the highway. It only does it when it is warm. First thought was throttle position sensor, but no trouble codes are indicated by the computer, and everything checks out in terms of resistances. If I take the computer out of closed loop by disconnecting the Oxygen sensor the problem goes away. The sensor is a Bosch unit, and is sending a signal. Has anyone else had a similar problem?

Difficult to lock center differential
Lately I noticed that it is quite difficult to lock my center differential, and once it engages it is awfully difficult to disengage. My Mazda dealer thinks that I may need a new actuator (servomotor?). I am wondering if anyone has had a similar problem, and thus a possible solution.
I would also like to find out how I can modify the anti-detonation reduction of the boost, which in my case often comes on as early as 13 pounds.
