I have 3 of them. And have worked on many.

Yes it is very similar to a 1.6l Miata motor. A cheap motor fix is to install a 1.6l motor out of an Automatic miata for the lower compression. they can be had for cheap. Swap everything over from the GTX (turbo, manifolds, oil pan, oil pump, cams, valve cover, clutch, pulleys, and a whole bunch of other doodads I can't think of right now from your busted GTX motor and it will work in a GTX.

Best site for forum help is Yahoo Groups 323gtx 323gtx : The Mazda 323 GTX Mailing List

It's cool to see that the old yahoogroups group is still a great source of info. I owned one for about 5 years and that list saved me so much time and money. Great people indeed. I hated selling my GTX and I find myself regretting it often. Fun little car for sure!

Funny I bought a 91 Miata that ran and came with hard top once for $700

I kept the hard top but in a fit of stupidity I traded that miata for another GTX. It’s going on a couple years now and I haven’t fixed the transmission in that GTX I traded for. It has just sat I need to sell it really.

I have another one that I drive on a regular basis. Sort of a daily driver. It runs strong with a chipped ECU and handles really well with some basic suspension tweaks I’ve spanked allot of cars at autocross with it.

Then I have a friends GTX that has lived at my house for the last 4 years. It has a built 323 GTR drive train swap puts out about 300hp to all wheels weighs 2600 lbs and I have fit 15X9" wheels on it with 225 tires. It is a beast. Fun as hell to drive but compared to the GT3071R turbo on my miata the stock VJ23 that is on it is a laggy thing. I had the two turbos apart side by side The stock turbo Mazda put on that beast has a bigger turbine wheel than a GT3071. Power comes on all the sudden and will surprise you. The AWD keeps it from swapping ends pretty well though when it does hit boost.

This is the one under the collapsed canopy at your house I take it. If I had known you wanted to sell that I would have made you an offer when I had money

This summer I was looking hard for one to replace our Integra because it's a piece of junk.

The GTX was fun, but it did require some fiddling to keep it a daily driver. I actually kept my entire toolbox in the trunk all the time and had a pair of workpants in case I had to crawl under it.
I started keeping the toolbox in the car after one Thanksgiving day I was in DC (3 hours from where I was living) meeting up with a friend when my driveshaft bearing seized. The only thing open was a gas station where I bought two adjustable wrenches. I removed the driveshaft completely, locked the diff in 4WD and drove around with a FWD GTX for several weeks while I located the only spare driveshaft I could find in the country (in a junkyard in Washington state). Fun times.

I did meet up with some other GTX owners at the Susquehanook Trail Pro Rally in Pa. one year. There were 6 of us there. Being from Ga. I had only seen two other GTX's on the road ever so it was fun to get a pic of 6 of them together.

They seem to be all over the place around where I live. There are 2 in my neighborhood, 3 others that I see around town a lot and 3 at bobs house lol. A guy delivers pizza in one of the cars in my neighborhood. I tried to buy it from him one day but he wasn't having it. Said he got it from someone for 600 bucks and wasn't ever selling it.

I know all about the fiddling with them to keep them running. If you arenít prepared to work on your car regularly you shouldnít own a GTX.

No way that thing is worth 3k not running. Prolly more problems on top of the bad motor, too. Looks molested.

Interesting assessment, Ive never been able to physically compare the vj23 to any other turbo, but it certainly does spool hard/suddenly!
