</TD><TD class=alt1><!-- message -->I agree with Terry,

I have installed over 100 kits on Mazda 626(Capella in Japan) NON US, with exactly the same motor/tranny as the P5. They are all running 8 psi and 175-180 whp.

One one blew up the transmission because he was playing with the car neutral dropping. Of these cars, some have over 2 years and over 50,000 miles. In south America there is a lot of hill climbing which puts a lot of stress in all transmission components.

So, I would say, it all comes to how you drive.

exactly what juan says. i have an auto p5 with hiboost been over one and a half years. don't boost over 8psi, don't be an idiot with the tranny. and the auto will definately hold you back

Just Boost it up until yor Tranny blows and then go here.

If i do the transmission upgrade then how much do you guys say i could boost it to

 

[peepsalot]

Not much more before you gotta start worrying about the connecting rods.

I think Level 10 are the ones to answer that question. I'm pretty sure I read on their site that they build 'em to handle like 500 horses.

if you're only going to boost at 8psi, couldn't you just find a used mazdaspeed kit? wouldn't that be cheaper?

lentech also builds transmissions. turfburn also sells trans cooler kits.

where can i find one of those

where can i find one of those

wrecked cars

 

[bazooka joe]

there's another site that sells the mazdaspeed turbo kit...it's had something to do with mazda motorsports...and the kit is not 'complete" for some reason...i'll see if i can find it...oh ya, the speed ecu isn't going to work with your auto either so it might be best to consider an aftermarket kit

 

[Captain KRM P5]

that site is SR motorsports

 

[Robot Romeo]

there was a complete kit for sale in the marketplace a while back. i think it was $2000. so if you don't go to sr then you keep checking the marketplace.

 

[pingdum]

I saw one in the For Sale Section today.

r u saying i cant use a turbo from the mazdaspeed because of the ecu

 

[Boston5761]

could i bolt up the mazdaspeed kit to my p5? what all will i need ecu, etc?

 

[Black_Protege_5]

You can use the mazdaspeed kit but you will need a piggy-back system like the apexi afc or something that will control air/fuel. You won't have to worry about any internals because they are the same but you will need a different exhaust setup.

 

[Boston5761]

couldnt i just run the msp ecu instead of piggy back?
