@ High carb: thanks and there's some parts I'm prowling the classifieds for to really finish it up like a not completely fried dash board I gotta redo the rear panels and a few things but, it's coming along.

@ourxseven: the steering wheel was picked up at my local Autozone but, most parts houses carry them round $30-40 bucks depending and mounting was easy no problems just get the FC hub from Summit racing and it'll bolt right up this wheel uses part # GRT-3597 and it's $18 plus shipping. that hub is different from the other billet ones out there so get that part #.

UPDATE ! !
No pics as of the moment but have an engine on the way from a forum member, a 12A large street port with ALOT of extras from RX-7Chris (thanks again man) a box of parts from mazdatrix for the trans as well as fresh plug wires and plugs (already had these), installed a fresh set of ACCEL Super Stock Coils. Pics upon arrival.

PK_12A 02-29-12 12:36 AM

The last 2 days have been very productive as far progress, installation of
all the extras that came in the set up from Chris.

Day 1, began FC fuse box install, started fuel pump wiring with relay and
cut switch, mounted the Carter fuel pump, Holley adj. fpr, all fan wiring with
relay, and new battery installation.

Day 2, finished wiring up the FC fuse box, fuel pump wiring and connected the
amp wiring to the FC fuse box, the day culminated in the installation of the engine
and transmission. Also connected the engine harness, ignitors, slave cylinder connected
all my gauges and the ran out of time while I had light then the sun set and I had
to call it a day.

Hoping I can get it fired up tomorrow before work, first things to do
is put the alternator back on and hook up the wiring, hook up the oil
cooler, install the radiator and hoses, add fluids, connect the starter,
install the exhaust and then, we should be good to give it a go.

Pics real soon got a bunch to upload but, been real busy getting this in
and ready to fire up and finally take her for a test drive.

More real soon.

Ok still got some more pics to grab before I post them all but, we got it going and it's bad ass I seriously love this engine the exhaust is awesome it sounds great runs sweet and makes my fb scoot. I may post a video. Found I have a coolant leak from my bottom radiator hose on the top side by the water pump and the thing is my bottom hoses were brand, my one off the last motor was only on for a couple hundred miles and it leaked in the same spot as this new one I'm confused. More as I do more.

RX-7 Chris 03-12-12 10:58 AM

I'm glad the motor is running great.

Where exactly is the coolant leak? Could it be coming from the short hose that goes to the heater core?

PK_12A 03-13-12 02:47 AM

I have 2 it seems one is straight from the top part of the bottom rad hose on the pump side almost like the hose clamp isn't sealing the hose, not sure why the other seems to be coming from behind the pump itself like the gasket is leaking, oddly just a drip at idle more under load. No biggie on either the hose is the more annoying because I picked up ANOTHER new hose and it's leaking in the same spot, the other I figured is just from sitting a while, this was something I meant to do before stabbing it in. Some gasket paper and silicon and it oughta be good to go on that part, the hose may require some creativity, my dad told me about an old dirt track racers trick where you put some hi-temp silicon in the rad hose and on the fitting clamp it all down and let it cure and it should fix it. Real soon I'm gunna get some RB silicon hoses. . . . maybe. I do know this, it is a great engine lots on tap, runs smooth pulls great, well worth the expenditure.

PK_12A 03-16-12 03:37 AM

And we have the pics
 
So haven't got much done but, ALL coolant leaks have stopped but, I bring you the much promised pics, gunna get some more now that she's back in one piece,

Looks good.

I would recommend moving the fuel pump so it is pointing down. I had it mounted up by the rear end. You may burn it out with the way you have it mounted. Give me a call if you have any questions.

Here is a pic of where it was installed:

After getting to drive her for a while an unfortunate event happened, my slave cylinder went and took my clutch with it, fried it luckily I had a spare that was only lightly used from the other engine so up on stands she went for a clutch swap and slave rebuild. Should have her back up and running within the week.

PK_12A 05-21-12 03:39 PM

Got her all back together friday and been driving her around and the clutch/slave cylinder was definitely the problem, hooks up real nice now, also fixed the reverse light switch so now I have back-up lights again yay. recived some free donations from forum member YellowT2 and put them in, next day off they will get repainted then some pics.

PK_12A 07-17-12 03:38 AM

Just figured I'd post a little update, haven't done a lot lately accept the t-stat install my 3/8" fuel feed line and tracked down my leak, turned out to be on my temp probe in the back of the water pump, fixed with thread seal tape. Finally got to take her out and open her up recently and I must say this thing pulls great to read line in all gears and will launch pretty hard. Love how the car feels with this engine set up.

RX-7 Chris 08-30-12 02:41 PM

glad the car is working good.

PK_12A 08-30-12 09:38 PM

Chris I must say, you built the power-plant and set up I was dreaming my 12a to be and I owe a thanks to you for helping bring my project together and keeping it alive. Found an unfortunate problem today, the used tires on the front have decided to go belly up, left front has bubbled and that means I need new front tires on the front before I send her on a truck to my new location, otherwise she's ready for the trip.

PK_12A 12-30-12 09:02 PM

Been a while since I updated and hadn't I figured now was a good time. Not much has really been going on with the 7 lately as winter is here, swaped in a 6.5 powervale due to a high rpm cut out, did that and boom problem solved. Now she purrs like a kitten and pulls all the way through red line. That's all for now till we get a few warmer days and I get some cash.

So reassembled and wasn't the issue seems something in the rear is busted more ad the story unfolds.

RX-7 Chris 02-05-13 11:35 AM

the car is looking and sounding good.

PK_12A 05-12-13 11:41 PM

Wow can't belive it had been quite some time sincw my last update, due to weather and cash flow my project has come to a temporary halt. Winter kicked my butt the worst as not having indoor workspace I couldn't get outside, not to mentionit was a wet one and spring so far has been the same unfortunately. This week my Dad and I are going to wire up my brother-in-law's Jeep and get it finished for him then we are starting in the 7 so hopefully soon I will have a more exciting update and funds and time willing suspension, brake, and tire and wheel upgrades will soon be next on the list. As far as the shocks/springs, I am seriously considering the T3 coilovers seem like a good product at a decent price. Now I haven't quite decided weather to do the paint and body myself or farm it out yet, any thoughts from those reading? More soon . . . And thanks for the kind words Chris.

Ok 2 part update,
First picked up a back-up rear end should be here within the week turns out more is wrong than wheel barrings more when it gets here and we tear everything out.
Second, my wife is pregnant! The last couple weeks have been hectic since finding out, with doctors appointments and all. More on THAT as we find out more. Another rotor-head in the making. . .
