turboing 1990 mazda 626 lx

who knows the bore and stroke of the 1988 ford t-bird (2.3l turbocharged)
need the info, hoping that a little boring of my 1990 mazda 626 lx (2.2 l n/a) might house the pistons. and maybe house the rods as well just asking before i start this project got the t-bird in front yard (t-25 hybrid turbocharger intercooled).

A little boring? Try 10mm more than your stock bore.

The rods won't work either. Just because it's an engine and your F2 is an engine, doesn't mean the parts are interchangable, especially pistons that are 10mm larger diamater.

I'll leave that alone, it speaks for itself.

Thats not the turbo that is comes with either. If you've managed to swap a T25 for either the RHB52 VC34 Warner Ishi or aiReasearch/Garrett T3 60 trim, you've downgraded. My bet is that you don't know the difference between either of the stock turbos and the T25 to begin with.

Dude first off do some searching I've been flammed on so much about my turbo LX project. Right now its on hold until I fix my front end (got into an accident). But you really dont need to change pistons. I see the New Member tag and I've seen you get flammed before for not searching. Either way you dont need to swap pistons. Correct me of I'm wrong but I think the compression on stock LX pistons are 8.9:1 and GT are 7.9:1. 8.9:1 is a good number to boost with, so dont bother swapping pistons. Fastest95PGT is boosing on 10:1. But again dont bother with pistons. Worry about drivetrain as that is the biggest problems with the LXs.

<------......................... Go ahead.....hit the karma button.....dont be afraid.....

Metric measurements on an american engine?!? Thats just the start of the problems!

turbo = 7.8:1 n/a= 8.6:1


8.6:1 is even more boost friendly than 8.9 but this project will probably never leave the ground and if it does, ull likely see a "parting out: 1990 626 LX" thread in the coming future..


i need one of these pipes.. desperately.. please contact me if you have one (and its not rusty)..

3.780" x 3.126" it won't work in inches either.

The only way I'm parting out my car is if the repairs from my accident are way to much and my insurance company totals my car. If they dont total it (which I dont think they'll do) you be seeing a thread called "To all who said I wont do it :flipa:"

I would have used more happy faces salluting, dont give up on your project, however I thing ROBERT 89 GTP was talking about JAPSTYLE's 1990 626 lx, remember you have a 91 MX6 lx.

there is a reason that the comp raitios are as low as they are : the cylinder head design is as old as the foundations of the oil most of you put inside it. mazda would have increased the compression ratio to increase engine efficiency and power if they could have done so safely. it does not make sense to say X comp ratio is good for boost without reference to the head design. the pentroof design that fastest95s engine and the fe3 use is MUCH MUCH more detonation resistant (along with much better flowing), thats one reason why he gets away with boost on 10:1.

not saying swap the pistons, just saying that you wont be able to run as much boost as safely with the higher ratio. stock f2t boost should be fine, but boosted f2t bosst mosst likely will end in tears. ofcourse all of this is also octane and retard dependent.

just pointing out that 10:1 in KL is not the same as 10:1 in 12v mazda f series head.

What about the even older chevy and ford 2 valve heads that have no problems handling boost and putting down crazy numbers. Who cares how old the head design is? The Mitsubishi 4G63 head is just as old and its still in use with higher compression and no problems to this day. As long as you have the fuel so you dont run lean and the cooling so your intake temps stay low enough you can do whatever you want.

Sure it might be easier to run higher boost on certain engines because some are more efficient than others but 7.8 to 8.6 is not enough of a difference to tell people it cant be done or that its gonna be a potential problem.

Without debating the detonation resistance of either, I would opine (and Mazda would agree) that the F2/F2T cylinder head is also a pentroof design.
