Build is looking great! I'm glad you're ahead of mine, reading through this and some other turbo builds has definitely been a big help for a first timer.

 

Good luck on finding the 5 speed. Can't wait to see that engine in the car!

Hey thanks! The kind words mean a whole lot. And I am very happy that you are learning stuff from my experiences.

 

I'm definitely trying to be more concise and descriptive when explaining what I do to the motor, and how I did it, etc...Not only to help others, but also so I know my exact process in case I need to go back and figure out something that went wrong.

 

Megasquirt will be a long and arduous process, as I intend on writing how I do it step by step, with even more pictures than usual. I'm now spending lots of time researching and understanding the system, so when I go to make my purchase I am well informed. But until then, I am going to slowly work my way to the back of the undercarriage of the car, cleaning, painting, and replacing as need be.

 

 

Thanks again for the compliment! It certainly makes this whole process much more fun. Cheers! :cheers:

 

 

 

Turbo parts still to buy before Megasquirt:

 

Oil cooler

Radiator + fan(s)

MSD-6AL

Greddy RZ BOV

 

Drivetrain parts still to buy:

 

5 speed

r200 (not sure if I can swing a LSD yet, but either way,)

280z Mustache bar

CV's

MM adapter

 

 

 

Then I think about suspension.....Ugh...money money money mon---ay..

With a fresh manifold gasket, I mounted the exhaust manifold, the turbo, it's oil line, and the shaved n42 intake.

 

Also, I added yet another dedicated vacuum port for my MAP sensor for megasquirt (I completely spaced that out) for a total of 3x on the intake. (not including the stock fpr port)

 

Here it is all bolted up and tightened down.

This will push me to source out a 5 speed, I can't really hang the exhaust until I reinstall some sort of transmission. It's progressing.....More to come.

Intercooler piping work has begun. Getting fitment right, making sure for easy access, and I still need to weld a couple bungs to the section just before the intake. One for the blow off valve, the other for a GM IAT sensor.

Also, I'm planning on going with black couplers, I HATE the blue, and will eventually powder coat the piping crinkle black as well.

But for right now, until I get the car moving under its own power once more, they can clearly wait....

I need to shorten the piping between the intercooler and the radiator support, as well. The gap is way too big. However, I'm waiting for my radiator to arrive before I do the final fit.

Fun work!

Okay, so today I started playing with my fuel lines...

I began figuring out how I was going to get the fuel where it needs to go.

I changed the routing of my fuel feed line to now feed from behind my motor.

Since I changed my fuel rail, I also needed to find a new place for my fuel pressure regulator.

 

I decided to mount it to the front of the motor, I'm not 100% on if I will be satisfied with it here, but I thought it was a pretty clever, and almost OEM looking spot. Let me know if you think this will be a problem? The only issues I see is potentially vibration? Maybe I'm over thinking it. But anyway, I think it will work out pretty well.

 

Err...I'm hoping so at least.....

 

Oh, I made some hard lines too, I think they give it a really clean look.

(I intend on putting a fuel filter in line before the injectors, I just didn't have one handy for this mock up)

 

Here you can clearly see my fuel circuit.

 

Comes in from behind the motor, leading to injectors, then to the regulator, then to the return.

FPR location is kinda slick....you're gonna have to run a real long vacuum line to it now though. It's kinda nice to have it all more out of sight by putting it on the firewall somewhere.

Sweet build too. I've been taking plenty of mental notes on your process, and the quantity/quality of pics is very helpful...a much more patient man than myself for documenting this whole thing.

Thanks, Mate! :cheers:

 

I thought it was a pretty neat spot for it. And yeah, one of my other concerns was the long vacuum line as well.

 

I did a quick measurement, and the distance from the stock FPR vacuum port on the intake to the current mounting position is roughly 22-23 inches.

Then I measured to from the FPR port to the firewall, and it ended up being around 20-22 inches; was also roughly the same to distance to the passenger side inner fender, the other spot I contemplated mounting the FPR.

 

I figure the +/- a couple of inches is probably negligible.

 

And aesthetically, I actually don't mind the look of the regulator in plain sight. I actually kind of dig how it looks, haha. I also figured this would be the easiest place to access the regulator for troubleshooting, service, and replacement.

 

I toyed with the idea of putting it on the firewall, but there just didn't seem to be a good spot with easy access for maintenance. Especially given the odd shape of the regulator. I'll just creatively run the vacuum hose, and I think I'll be in good shape.

Thanks David!

 

And yep! I'll definitely be there. Whether or not the car is ready is always the question.... And as of now, that is my intention. But we all know what happens to the best intentions.

 

It all depends on if I can keep my pace working on the car. One of my biggest hang ups is trying to source a 5 speed. So if you know of anyone with anything resembling a 5 speed. Let me know, as I currently don't have a transmission for the car.

 

Then megasquirt begins, and I expect to have a few hang ups there as well, but there's nothing I want more than to show up at the show in the car.

 

either way, I'll be there!

The 240sx unit is something I was going to suggest!

 

While the initial cost of machining the bell housing seems like it would make this an expensive option, the low cost and ease of finding the KA-5 speed easily offsets the difference.

 

I've literally had someone deliver a KA transmission to my door for $50. Supposed to have 65k on it if I recall correctly? Doesn't really matter when I can replace a gearbox for under $100 whenever it goes bad :).

Thanks guys,

 

                  Yeah I had considered the KA swap, and if a nice transmission popped up I probably would have jumped on it, but I'm going to pull the trigger on Pcakes55 rebuilt 83 n/a 5 speed.

 

This way it works out well so I can swap the transmission with ease, and I can focus big time on Megasquirt. Who knows? Maybe this thing will actually be running sooner than I think!

 

Also, I'm definitely going to pick up an Eastwood Hot Coat Powdercoating kit, and I'll do my intercooler pipes myself. I'm pretty excited to try it out. Just need to source out a junk oven to stick in my basement. :)

 

So, in the meantime, while I wait for parts, I have been adjusting the fitment of my intercooler piping.

 

It had to be shortened quite a bit. It's pretty close now, but I still have another inch or so of adjustment to play with. I just need to wait for my radiator to arrive before I make the final fitment. Then I fab the intercooler mounting brackets.

 

Other than that, not much to report.

 

Here are a couple of pictures of the shortened and adjusted piping. Note the improved fitment. (ignore the ugly blue couplers)

Throw out bearing install:

 

Since I am running a 240 mm flywheel this is the combination of parts I am using with my ACT clutch kit.

-240mm 2+2 flywheel

-280zx turbo/2+2 throw out bearing collar (see picture for product number)

-ACT clutch disc

-ACT Heavy duty Pressure plate

-ACT Throw out bearing

Also have been playing around with the first gen Mazda Miata/MX-5 A pillar 2 gauge pod. Figuring out what will need to be cut.

 

NOTE: I dropped my damn boost gauge (like 4 months ago) about 30 seconds after taking it out of the box. Darn thing popped right out of its carboard holder, and flew about 5 feet away on solid cement. So I think she may be beat, as indicated by the 4 pounds of perpetual boost I'm running. I thought about trying it anyway, and maybe it'll reset with some vacuum run through it, but I'm not going to waste the time. I'm probably just going to replace it, and call it done.

Cleaning up lots of odds and ends today.

Nothing glamorous, but progress nonetheless.

-Finished plumbing up my PCV system (since I relocated my vavle forward on the intake, I had to shorten and adapt the 280z OEM PCV hose)
-Fit up the exhaust and began taking measurements for hanger locations
-Began figuring out where I want my blow off valve to be, along with my GM IAT sensor

Oh, and some better pictures of the Miata gauge pod, and where it will be.I can't wait until I'm surrounded by all those gauges lit up!

Okay so as I once again wait on some parts in the mail (electric cooling fan, and some other misc goodies)

 

I got a new toy to play with!  (Be proud Ryan)

 

photobucket-5338-1363303017615_zps557eb0

 

My first project is powdercoating my intercooler pipes.

 

And I finished my exhaust (minus paint). Tucked up there nicely.

Nothing major, as I am once again waiting for parts.

Here are some small things that I've wrapped up in the interim.

Coolant line leading to throttle body- Made and installed

photobucket-46334-1363657408568_zpsab88f

Remade both of my hard lines for the injectors because before the fuel filter was touching the coolant feed to the heater core. Hahaha!!!

So needless to say, after some attention, the fitment is much better now.

Also had to slightly modify the front line to not touch the top radiator hose, although it doesn't matter as much as the other line, because it's just going to return to the fuel tank and be cooled anyway. But it looked bad before in my opinion.

photobucket-22725-1363565396529_zps55656

photobucket-29534-1363657032905_zps8dc1e


More small details...

Intercooler brackets, roughed out. Not bolted on, just in place.

photobucket-26102-1363657077362_zps19611

Throttle linkage- and pedal adjusted. So the throttle body now opens 100% at WOT.

Another couple shots of the current state of the motor and assembly.

Things to do this week. (parts permitting)

-Tap my thermostat housing for 3/8 NPT (when the tap arrives this week)

-Mock install of electric radiator fan and thermostat placement (when it arrives this week)

-Powdercoat majority of intercooler pipes (when powder arrives this week, and when I get a toaster oven)


More surely to come.....

Electric cooling fan arrived today.

 

Derale 14" Tornado electric cooling fan (with thermostat package)

 

1350 CFM 10.5 amp draw

 

I had to trim the bottom of the fan shroud ever so slightly to get it to fit on my radiator. It's a nice snug fit now.

 

I had originally opted to make some sort of bracket for it, but after seeing the clearances with the 3 row and the water pump, I think that's going to be something for another day.

 

Until I figure that out, I'll just run it with the cheap plastic mounting tabs, which I'll note, that I am quite surprised with their strength thus far. We'll see......

Okay so I picked up a large toaster oven, and since my 'wrinkle' powder isn't expected at the post office until tomorrow, I took today to experiment with the machine, and began figure out the powder coating process.

photobucket-2246-1364181589650_zpsa4de05

photobucket-47624-1364182344628_zps5afb8

First impression:

LOOOOOOVE IT!

So much fun, INSTANTLY rewarding and very gratifying.

Also, not too hard.....can be sort of messy though...

Here are some of my first experiments.

First was a skeleton key a friend wanted me to try to coat red.

photobucket-60885-1364181544123_zps12a73

Then I coated my fuel return line brackets 'machine grey'. A small detail, that perhaps will go unnoticed, but I like it. And at least now, they are protected, before they were just bare metal.


Before

photobucket-32577-1364181571561_zps650d6

After: some blemishes, but I put VERY little prep into these.

photobucket-12605-1364181515291_zps387fa

photobucket-48015-1364181497746_zps22fa6

Tomorrow I do my intercooler pipes. Er....at least start them.

 

Wish me luck!

Aside from having to order more powder, which I am blaming partially on my inexperience. That, and having ordered a small amount just in case I royally screwed things up, or if this turned out to be a failure.

 

Got 2 of the pieces done. I really like how it looks. The color is "wrinkle" black.

 

I'm certainly enjoying myself.

Okay, so today I.....

 

 

 

-Tapped thermostat housing to accept all my various sensors.

 

Top left is Autometer coolant temp gauge sensor.

Bottom Left (now tapped 3/8NPT) is for GM Coolant temp sensor.

Top right is plugged, obviously.

Bottom right is also tapped 3/8NPT for the sender on my cooling fan. (set to kick on at 180 degrees and kick off at 170)

 

photobucket-41236-1364334355385_zpsd54e0

 

Now I need the gaskets, and a fresh 160 degree thermostat, then I can bolt that in place for good.

 

Another thing down.

 

Ordering an oil cooler tomorrow or the next day.
