Well tried to fire her up last night but the fuel pump didnt want to turn on?
Mspnp says the pump is on but I didn't hear ****, no fuel in the lines either, then I get an injector blowing out...
Needless to say I'm not racing today lol, really curious what would cause the fuel pump to not come on though. Doesn't prime when the key is in the on possition or when cranking.
It was late last night so I'll check into it today and hopefully get it running.

She runs. Primed fuel pump, replaced an o-ring on an injector and swapped out the fancy aftermarket cas and coil packs for oem miata equipment. Fired right up. Rear oil pan seal was crappy and she started leaking oil pretty bad so I shut her down and pulled the tranny and flywheel today. Sealed it back up and will re-install the tranny tommorrow.
This engine is loud as hell. The exhaust mainly (as in it sounds like a ******* mustang :S lol) but the the top-end sounds like the hla's are dirty, although I didnt run it too long so maybe shes just alittle out of shape having not been run in so long.
Regardless so far so good, I really underestimated the cooling lines and where they have to be run, it looks like **** honestly, but I'll get some SS hardlines made up this winter to clean up the bay alittle.
Can't wait to put the boost to her and see how long my tranny lasts lol.

Starter mounts the same as it does on the miata(using the miata trans remember)
As for updates, well I drove it 30km home and found I really need a restrictor in the feed line to the turbo. Also when I was pulling the old motor out I found my manifold had a bad crack through the outlet flange so it needs replacing.
So its parked for the winter, I need some bigger injectors(750's) and a new fuel pump(still on the oem 1.6 lol) and I'll be making my rail a dual feed set-up.

Little update:
So my rush install job last fall was stupid so I decided to pull the motor this spring and fix everything that was sub par.
I also was thinking, since finding the mbsp and I was curious, what else was done to this engine that I didn't know about??
Well this was
And that makes me very happy lol (see: shim-under-buckets).
So Now the engine is out of the car and I managed to give the bay a respray and started cleaning up the turbo lines ect as the GTX motor has slightly different coolant routing (obviously)
So heres a couple shots from the other day, note that I have the lines routed differently now and the timing belt is done (tricky to do by yourself the first time by hand)
The intake manifold is one I bought with a 99 head from FM, its ported out pretty good and the "paint" is a heat dispersion coating (didn't come off in the ultra-sonic bath).
Anyways, I'll get more pics/vids when it gets up and running again (this month)

I doubt the GTR ecu would plug into the miata harness, and I'm using a MSPNP anyway as this is a fully built motor and the stock ecu probably wouldn't like the things I'm doing so I would not even bother trying to use a stock ecu.
The GTR motor is different and has a lot of things that identify it vs the GTX motor, just wikipedia it and you'll see for yourself.
Thanks, motor has been running strong for awhile now.

I've done diff/clutch/motor swaps solo in -20C weather. No one has bench pressed there tranny or diff laying outside in the snow as much as I have the last 5 years (or worked in the winter outside on their car period lol)
As for the other guy;
I actually don't have any pics of the motor in the car (after looking around, I'll take some tomorrow) but really its just a bp motor, ya its got a different head and valve cover and stupid fwd motor mount still, other than that its just a miata motor. (mine just happens to be build is all)
Don't bother doing this swap unless you get the motor for free.

Like I said, if the motor was built and you got a screaming deal (my case) and you already had all the extra pieces from another 1.8 (mine was blown up) it makes sense.
If this is your situation just save the money and buy new pistons and rods for you miatas current motor.

yep only the GTR is worth looking at...
The compression is lower than a 94-97.(9.0 is as low as you want to go on a stock engine (bpt is nothing else than a 8.6 compression miata engine. That is too low...for good power off a stock engine...)
These 94-97 blocks are the one you want... (94-95 have oil port on exhaust side)
The GTR has special pistons and rods... The rods are bigger than the 1.6 gtr (the one with bigger rods than the miata)
left to right:
GTR, GTX & B6T Rods

The pistons off the gtr has special oil ports on the inside(cooling???)
http://img354.imageshack.us/img354/4...rpiston1pz.jpg
Only 8.2:1 cr...(but ready for high boost!!)
I have a set at home..
The crank and head are not more interesting than the miata.. Even ported it will be as good or worse than the 99-00...
Still they are nice high hp motors but worth the trouble??
In my opinion, NOT.
