Easy. put in a new intake and exhaust, then an MSD ignition box, to advance/retard the timing, put in some bosch 4 prong platinum spark plugs, hollow out your cat converter, and find a way to up the boost on your turbo by way of your computer.

Good luck trying to find one. It is next to impossible to find one. I looked over one year before I located one.

actually you want 250HP you can do it with 14psi on turbo-blue gas on your normal GT motor.

But with the GTR, all you´d have to do is make sure you are running the GTX/R ECU. So you´re timing and Fuel is run by that, then use $2 in a valve you can make at Home Depot and put it inline from the compressor housing to the wastegate actuator housing. Screw the screw down. Its the cheapest way to make a boost controller. Or you could spend 800 bucks on a A´PEXi AVC-R. That would work too.

Almost forgot James, here´s general info:

Bosch Platinum +4´s are a "hotter" type of plug. With a boosted motor (Super, Turbo, N20) you want to actually think about finding colder plugs. Colder plugs resist from forming "hot spots." Hot spots are the cause of pre-ignition and detonation (Knock). The platinums work great in N/A motors, but in a boosted app you want to think about other stuff.

ZEX, VENOM, NGK all make great plugs for heavily modified applications. I think Denis runs with the Zex ones.

Oh...hehe let me take my foot out of my mouth, I didn´t think about that when I was typing it earlier today. Yeah I knew the 4 prongs were hotter, but I base everything on my engine, so I forgot about him asking about a GTR motor. I have 2 prong platinum tips in my car at the moment, and I like them, but my car is N/A. Thanks for the reminder Blade.

do you guys think its a good idea to order the gtr engine from www.corksport.com it is going to cost 2 grand or do tou think its better to get the 180 hp gtx engine and spend the extra $1000 dollar towards building that engine to 250hp since that motor only cost $1000

no prob about the reminder James, it was knowledge for everyone else. I ran the +4´s in my car before I got the turbo. Now I´m running autolite platinums that are colder, but they are fouled already. I´m trying to find plugs that will work well with my MSD box.

I say just build your GT motor. If you really want to swap get the GTX. You´ll get one faster and just look at Denis, Orlando and Adam. They´ve proved you can be a God in your car with only a GTX motor.

Ok Here´s an excerpt of Blade´s from the "what does the BP stand for" thread (note: I Know I´m copying it, but hey, I´m sure Blade is sick of typing it over and over and over and over, and yes he knows way more than me on this subject.)


Quote:

"The GTX is technically a Mazda BPT. It IS our motor, except it runs lower compression (8.2:1) and came with a turbo (IHI RHB5 VJ20). (Blade)
think(s) stock they run like 6-8psi of boost.

They were never available in the EGT. They actually came in the 90-94 Mazda 323 GTX. But because the outside of the motor is the same, cept for the turbo, its a drop in for the EGT.

Two other versions of the 323 were made, the GT and GTR. The GT is our EGT motor. the GTR is the GTX motor with some different internals and I think a little better flow in the head. Either way:
BPD (GT motor): 127hp
BPT (GTX): 180hp
BPT (GTR): 210HP"

End Quote

There´s the differences between the BP and the BPT (GTX, GTR) motors.

building the GT motor is like building any other motor. But what you want to build it for is a WHOLE lot of thought. Do remember that your GT motor has forged internals, so you´re all set up for some boost.

Putting together a turbo kit for the scort is a long and frustrating experience. I have no patience and rushed the project, but I´m crusing with a turbo no...not really any boost, but I have the turbo. I say start by making the decisions like if youre going to get a GTX ecu, or a Haltech or just piggyback all the systems. If you chose to piggyback start with ignition, then fuel...full system, injectors, pump, computer. Then get your airbox all set up and start getting all your hoses and clamps, then do the turbo install last. It will save you a headache or two...or like the extra 2-300 bucks I´ve spent and wasted on rushing everything

Hey James, thanx for copying that over too. You´re right I would of retyped it. I guess it doesn´t frustrate me at all to retype that stuff because I like sharing the knowledge I´ve learned. Lately seems like the only thing in life I know.
