i can't really relate to this post because where i live nobody really cares for the MX6 1g, so you can get a turbo one for like..... $700 sometimes, in drivable condition too......... so i just can't rationalize this swap in my mind
The naturally aspirated F2 engine makes 130 ft-lb torque at the wheels.
The Turbo F2T engine makes 190 ft-lb torque at the wheels at factory boost, add a boost cut chip and boost controller (+- 40$) and turn the boost up to 15psi and you get about 250 ft-lb torque at the wheels. Upgrade the turbo and add extra fuel and you can make close to 400 ft-lb torque on the stock engine and factory ECU. Add timing control or water meth or engine management or run E85 and run 30psi boost....
I had a 93 probe GT, it had a KLZE, stainless shorty headers, cold air intake, side skirts... the car sounded really good but was slow as can be, I bough it for 800$ with the intent to sell it, it needed tires and seats (shoowed up at my shop with milk crates for seats and the driver shreaded the front tires doing burnouts). The only people that where interested where very young and their fathers wouldn't let them buy it.
When my 89 MX6 GT got hit I needed something to drive, my choices where the probe GT and a 1988 Mazda 626 LX automatic, I chose to drive the 626 auto N/A because the probe looked sporty, sounded sporty but was only 200hp and looks like a tampon with wheels, I like straight sharp lines on a car (Ferrari F40) and can't stand curved rounded lines on a car (all porches). My shop partner drove it a couple of times and took it to the drag track, I never drove it once.
The F2T with a chip and more boost was faster that the probe GT.
To be fair I always loved the look of the 88-92 626 but was not a huge fan of the 1G MX6 because of the fender flares, the first time I saw 70's stepside pickup truck (when I was a kid) I though that is the ugliest thing I have ever seen and it made me hate fender flares, eventually the MX6 grew on me.
2years ago we sent the probe to the scrap yard where it belongs.
I can't rationalize spending 1000$ on a KLZE motor for a 32hp gain, or spending 350$ on a maf upgrade for a 25-35hp gain.
Guess I got spoiled driving F2T's all these years and expect a couple hundred more HP for 1000$.
The F2T has far more potential than the KLZE and KLDE in factory form. the KLDE has lower compression than the ZE and could run more boost than the ZE.
If you have to swap rods and pistons to run high boost on a car you chose the wrong car to modify.
I use FT-LB torque because it's what makes a car accelerate, HP is a meaningless # that represents potential work done over 1minute of time at that exact RPM and engine load. To achieve the actual HP number the car would have to stay at the same RPM at wide opened throttle without accelerating (increasing RPM's) for 1minute.
Mazda dropped the ball with the 2nd gen MX6/ 5th gen 626, in 1986 and 1987 3rd gen) they had the FET 2.0L 8valve non intercooled turbo, 626 coupe is a 2 door and basically an MX6, in 1988 they improved the FET increased the stroke from 86mm to 94mm, added 4 more valve, a larger turbo and intercooler and a stronger transmission = F2T, Had they continued on that path in 1993 with a cast Iron block, even stronger transmission, low compression pistons and even bigger turbo (whatever the engine displacement or number of cylinders) the 2nd gen MX6/Probe would probably be the front wheel drive equivalent of the 4th Gen Toyota Supra (capable of making 3 times factory power on stock internals), I could see the 2nd Gen MX6 as a turbo charged vehicle making 220 HP factory but capable of making 660 hp on factory internals and transmission. I would drive a second gen MX6 or run 2nd Gen engines in 88-92 626's. The Toyota supra got uglier with each new generation (more rounded and curved) but also got faster, the 626 also got uglier with each new generation but also got heavier, slower and less reliable. The 323 however did follow the correct path and in 1993 mazda built the GT-R (2200 made, japan only) unfortunately they are 1.8L engines and rare as hens teeth, but they did improve the BPT engine for this car and put in a much larger turbo...
Perhaps the only good turbo charged piston engine Mazda made is the F2T, the FET wasn't as strong or as capable, the RX7 rotary engine has huge potential but is unreliable at best even in stock form, The mazda BPD is too small and who wants to drive a hunchback car (piss pot) the Speed protege engine is crap, the Mazdaspeed 3 and 6 2.3L MZR engine is aluminum junk, you'd be lucky to squeeze out 50% more HP/Torque reliably without blowing the engine or destroying the transmission.
Yes I consider an engine to be "Good" based on the number of times factory power output can be doubled no matter what factory power is to begin with, a 600hp factory motor that can only handle 700hp isn't a good motor, a 200hp factory motor that can handle 600hp is a good motor. It's all about how much room the manufacturer left you to express yourself and make your car yours, what good is a 700hp car if any asshole can buy the same thing, drive it off the lot and be just as fast. It's not about how fast your car is it's about how fast you made it.
By the time you match how fast Urry_Rip can make an F2T set -up accelerate on the factory turbo using a chip and boost controller you will need a KLZE/ECU/AFM, headers, full exhaust, CAI, light flywheel... with money you spend on that he can upgrade the turbo, fuel delivery and clutch and still leave you as a tiny dot in his rear view mirror.
Maybe now you understand his interest in the 1st gen MX6 and making it a GT.
I can't wrap my head around why you would want a 1993-1997 ford probe? Unless you think of a car as a female, curvy, delicate, weak, temperamental, moody and unreliable than you made the right choice. I don't associate gender to cars but if I did it would be male, tough, reliable, strong and if you look at it wrong it will kick your ass.
