was thinking that since the current turbo is a t25 I think you could add the t28 from the mitsu line of turbo. just an idea since we are going to ned booost controllers and timers, and maybe some nice guages.

what do you guys think will fit that is already in production on current cars?

 

WHOA PEOPLE....if u get this car ....DO NOT!!!!....leave it stock....dont even touch the turbo or any major things...all u need is a boost controller...bigger exhaust...2.75-3" and larger intercooler....that is it!!!!!!!!!!!!.....nothin else....and u will have a beast!!!>....think it is currently at 6psi wit 151 hp at the wheels..u do exhaust...that is about another maybe 10 more at the wheels...turn the boost up...figure 10hp to every 1 psi....i say do 8-9psi...another 20 -30 hp at the crank...maybe like 20 to the wheels...u are almost at 180 at the WHEELS!!!!.....ultimate car...no testing it...i wish i was getitn this car cause i would finally be able to beat my boy in his type r...heheh...go hunting after these mods....

 

The MSP is runnign 5.2 psi of boost stock just so you know. and I'm sure the ECU will have a program to hit a fuel cut if it sees more boost than 6 psi.

 

I thought the MSP was running 6.9 PSI stock?

 

Right...... just like all those other turbo cars out there that can run higher boost w/o a fuel cut off.

 

It doesn't matter, I'll still woop it!

 

5.5lbs

 

Me too!!!

 

Remember those 'other cars" are built for turbo. the MSP is a STOCK FS-DE motor with a turbo kit slapped on it so they are going to restrict the boost. Super Street tested the MSP in this months issue and by their bosot guage they read 5.2 lbs of boost. as for the other cars try goign to 15 psi on a DSM and see what happens. Their stock is 12

 

I think some folks are very confused about boost and horsepower. Just because car A boosts 5psi doesnt mean it makes less Hp than car B with 15psi. If you want big boost numbers build a DSM block. Other than that it is kinda pointless to argue about how much boost a block can handle.

Here is my take on the MS prot. It seems what little reading I have done that mazda may not have upgraded the fuel pump to handle greater amounts of boost. I can't say this for sure since we can't compare stock part numbers yet. thea reason I say this is becuase of what the FM guys are doing with thier P5.

I am also wondering how the drivetrain will hold up to the preasure. Lets also take into account that the engine maynot be built specifically for a turbo, however the stock compression is pretty low, it does have an ECU that can handle a turbo. This is great seeing how I dont think you will need to run a Link or any other piggy back, although an Apexi afc would be need to run larger injectors.

I am still unsure where you get teh idea that turning up the boost will automaticlly invovle a fuel cut from the ecu, now it may detect knock and kill your timming, but i dont think it will run you lean causing engine damage or failure
