yes it pulls extremely hard, I probably should get a stronger rear end. The first diff mount I had ripped right in half.

Looking forward to seeing some updates.. I presume if you had a chassis side loom from a donor skyline you could cut and splice the guage wiring for the FD into it to get it to work that way? How much is the wiring adapter going to set you back? I believe on the engine side the electrics are all a self contained loom. Was there anything you had to cut and shut into the ECU wiring so far? I am guessing the ignition/starter goes through that somewhere along the line and needing joining in?

Cheers

Yea that might work. I think Im going to end up getting all autometer gauges that fit in the factory gauge spots.

The wiring was pretty easy I just spliced the skyline harness to the rx7s using pinouts.

I plan on getting rid of all the wires in the car and completely customizing it with new relays,fuses and everything.

yes, ignition wires are spliced in to each other

Cool. Any wiring pics you could pop up would be good?
That would be nice to rip all the old crap out and start fresh! At least you know where you are then!

Not really. The engine doesn't make that much tq or hp. Your going to need to upgrade quite a few things to "pull hard".

Your rear end broke cause you made that abomination of a diff mount with no knowledge of how your rear end works AT ALL. Stock FD rear end will hold more than enough for what you have, the problem is your engineering.

No, your Rotary tach is on a different pulse pattern than the i6. No amount of spicing will make it work. You need to get a box that can change pulse width or just get another gauge.

lol, we must have different ideas of pulling hard and what's a lot of torque. Im building a drift car and it has plenty of what I need.

I had a dumbass make all my old mounts and I knew it was a piece as soon as I seen it. It has all been corrected

I know very well how a differential works, there is no need to get so personal without knowing anything about me or the car. If you have a problem make a suggestion instead of an insult.

I second that.. No need to get personal. if you don't like the project get out the thread!
Thanks for the info on the tach though I presume you mean rev counter? assuming that runs of the crank sensors I can see how that might cause an issue.. So you need to fit a skyline rev counter then?! Or are such adapters an off the shelf thing?

How does what I said have anything to do with liking or disliking the thread? It has to do with him saying he needs a new rear end cause his "diff mount broke". Blaming Mazda engineers for not making a stronger rear end because your diff mount, that you said you had a dumbass make but you know how a diff works but you still put it on and tried it (which from one look anyone can see rebar diff mount bent into the shape of baloon animals and mounted all the COMPLETLEY wrong way, is a failure), makes no sense. You already copied my oil pan to a T, might as well copy everything else on my car including the diff mount, since it all had real thought put into it.

ill have pics of all the new mounts and everything when they get back from powdercoat.
I didn't say I needed a new rear end because the mount broke. The mount was on the car when I picked it up. I want a new diff because Ill eventually be pushing 400whp with my new turbo setup.


Yep, lol I copied your oil pan. Have you ever thought that since we have the same engine in our car, the way you have to cut the oil pan might turn out to look similar hmmm.....Im sure the old dirt track guy I sent the car to to make that oil pan came on the internet and stole your ideas...

FlyingFinn -
Reason is reading your posts sounds like you are coming all over with an attitude about the guy's build.. So what if it was all messed up first time.. I seem to remember in his early posts he said he was going to change it all once the car was up together. Not everyone can do a job perfect first time round ro has the facilities to do it.. But if they persist and get there in the end you should be giving them encouragement and advice along the way.. Especially seeing as you have the same swap? Why get pissy if his oil pan looks the same as yours. You should be flattered that someone has been inspired by your work if they had in fact copied it.

Anyway.. This isn't the school yard.. That's all I'm saying.. Enough already!

yea, sorry for the lack of updates. I have been busy with work and school.

I installed new black carpet and hooked the brakes back up with a deleted abs system.

Ill try to get pics up soon. I have been sand blasting and powdercoating the engine parts and there coming along very nice. Once I get them finished It should be smooth sailing!
