GTX swap

[mike_moss]

Oh.

[D323]

working on yours mike? I thought you had a KL? Or are you talking about the beater?

Yeah sorry I meant RX-7 injectors.

[mike_moss]

I have the K8 in there but with the car in storage for winter, I'm doing a mini-restoration in preparation for the ZE.

[D323]

ah... very nice.

you think you'll need the rx-7 injectors D323? cuz the gtx are 330cc, and the rx-7s srart at 460cc? then to go 550cc and up from there?

you should try and tune your car with the 330cc injectors, they should be plenty, i was told 330cc injectors would be prefect if i wanted to run T3 @ 8-10 psi daily, and switch it to 12-15psi for fun runs. cuz you'd be running rich at idle or partial throttle, which equals more gas spent.

lol just a though

Yeah they are 460cc's I realize that now, but I got the RX-7 because at the time I was looking at a t3/t4 for lots of fun . I decided that thats too much though and decided to just go t3 and enjoy the moderate boost.

With the RX injectors I have room to push the turbo up to its max (somewhere around 20 psi ) and not worry about needing larger injectors.

I'll be glad to run rich over lean. Besides with megasquirt I should be able to tune it just right.

oooh, you're running MS now? lol wow, went from SACF1 to SACF2 now to MS! lol

anyways, yea, you should be able to control fuel better with the MS

good luck dude

lol yeah I ditched the SAFC-II I had and decided to go MS. Actually I still have the SAFC-II forsale, but no bites.

Matt F. (had the MS prebuilts for sale a while back) built me mine. I still need to get a wideband o2 for the system... I am just waiting for tax refund for the cash to get one.

a little something I have been working on before I get paid again so I can buy more stuff for the swap.

[D323]

Bought more piping off of ebay so I can get to work fabbing up the FMIC piping... going to be fun.

Since the front mount is a MAJOR PITA, looks like making the piping go around it will be hella easier.

Found a guy who makes kits of all the parts needed to replace all the stuff on injectors... I am in the process of writing a how-to for those interested. All in all the kit is like 15 bux shipped or something like that and its everything needed for the denso injectors... Once I do the write up I will have a link with his email and website for others that maybe interested in doing the same.

For now the gauge pod has gotten 2 coats of black... I want at least 3 coats... then I will probably hit it with some clear coat. One of the gauge rings seemed to want to shrink on me making it want to crack... I had to use the dremel to grind the metal down... it works perfect now.

[D323]

Finished painting the pod, bled the brakes, torqued the front axle nuts, put on wheels & tires, made a bracket for the Distribution power block for the engine harness, pulled the masking tape off after painting, and fiddeled with wiring up the injectors for the car.

[Pastor_Protege]

I love the gauge pod. Good work Donnie.

[D323]

Thanks... I plan to bleed the rear brakes, wire up the rest of the injectors, and wire up the power for the engine harness (at least those things) tonite...

I need to hit up Autozone for some more MTF... I bought the only 2 bottles that AutoZone had...

I find by doing small stuff and writing it down like this it makes it much easier for me to get stuff done.

[Mazda_Powered]

lol, so whats left on the check list before you attempt a turn over?

JACK

[D323]

Exhaust (kit needs to be welded up)
FMIC piping (gets here today )
rad install
MS ECU install
PS lines and belts
drain tank and fill with 3 gals of premium and install walboro pump

I am sure there is something small I am forgetting, but thats pretty much it. I finished wiring up the injectors tonite, as well as ganked all the AC/ABS wiring and relays out. There are still a few plugs left on the harness I need to get plugged in, but thats on tommrows plans for me.

I also have to weld several things... I have cut away parts to make room, and I want to make sure that structural integrity isnt compromised. That and I need to fab some hangers for the rad and other stuff. I also plan on cutting and welding the front bracket to get it to work with the car since the LX **** doesnt work with the RS subframe that I have to use since the MX-3 chassis is different than the LX.
