Pics tommorrow |
Good luck man! Call me if you need anything or left something behind that you need.

wow i'm quite excited to see how this will go

Sabretooth (i think it's his login name here) has done this here in Oz.
The Miata water pump has a threaded hole for the alternator to mount to vs the BPT not having one (or is it the other way around?) if you use your sump all should be fine, but you will need to use your oil pump too. Pics at: http://mx-5.sabretooth.id.au/enginerebuild/ His site went down and I am unsure if he rebuilt the HTML (it's just pics)... |
is it tomm yet?

Well things went pretty well yesterday but we ran into one good snag...
Motherfucker has an 01 msbp on and we tried to "copy" what psituning did to make the gtx pan fit, notch and form out the pan. Then I thought heat, bad idea lol. While it looks entirely possible to just grind out a 94-97 pan to fit the msbp it looked like they ground the edge down to a 45 and pounded it out some how. So I'm looking for an oil pan today either kind will work. Another note, the turbo on this engine was smaller than the 48/48 t25 I had on the miata before the gt2871 and - have no idea how it worked at all lol. A two dollar coin would plug the inlet on the comp housing lol. Also need some new injector o-rings as the 550's were cracked in two and the one's from my 370's don't fit. The head and intake on the gtx motor were heavily ported, yet look really well done. So I promised pictures and you guys think I'm gonna flake out right, lol well we set the camera on time lapse and took about 1200pics that we'll turn into a slide show when alls said and done so you will have to wait a few 'business days' for those. |
How is the GTX intake manifold going to work for you?
I've done that swap and the EGT many times, let me know if you have any questions. EDIT: Email me if you have questions :) I'm not in the shop this week. |
Interesting that they'd do all that work and leave the tiny little VJ20 on there.

Stock for stock, there's quite a bit more than that for differences between the two motors...
Fireindc: No reason it shouldn't, with conversion to Miata use. |

is he putting in the gtx bpt? or gtr bpt?
still compression ration is lower |
GTX. GTR is typically referred to as BPD.
With the stock pistons, the compression is almost irrelevant if tuned right (8.2:1 vs 8.8:1 or even 9:1). Typically the motor failure comes down to user error, from what I have seen. |
So I fiddled with the pan and made it clear the mbsp, but will have to weld(jb stylez) the fracture I made in it yesterday.
Hope to have the motor in the car tom and maybe start it. I have gm coils and the wiring is yellow (power) orange and white, how do I find out which one is which with the other two? Also need to know what the color of the wires on the chasis harness as the plug was pulled off and not sure which way it goes on lol. Upon removal of the clutch I had to say I was surprised how much the disc had worn since the installed this spring. I guarentee it won't last all of next year, not sure if that's normal wear for a 6puck sprung clutch being raced and abused. Marc btw I'm not using the gtx int or exh manis, I'll b using my miata ones. I really want to use the miata alternator as its quite new and I'm thinking I should just swap the pulley on the alt to the gtx V-style...Rather than changing the crank pulley ect. I also have to look into reconfiguring my mspnp to run with no vaf and variable tps from the gtx throttle body. Dean |

ugg... distributor :(

Well the motor is in the car and everything expect the rad is hooked up. The water lines are going to be nasty looking as I'm running a hotside coolant re-route..Coils and aftermarket/custom CAS clears the firewall(barely). Motor will sit till friday to allow the jb weld on the oil pan to harden (and b/c I'm leaving town) and to make sure nothing is leaking, finished last night at 1am and didn't go over much.
I also found a brutual crack in my turbo manifold..Crack is right through the outlet flange and through the weld...Not to happy about that, luckily the neighbour where I'm doing the swap had some stainless rods and patched it up good enough for now. I'll start a new thread with pics and results sometime in the next week and let everyone know how she runs. |
