Meh. It's just a NNARP, after all. (IMG:style_emoticons/default/av-943.gif) (IMG:style_emoticons/default/lol-2.gif)

Congrats! (IMG:style_emoticons/default/beerchug.gif)

Agreed. It’s no 914. Especially yours. It had the right stuff to satisfy my cravings while I wait for you to get bored with Grey though. ;-)

Come on Tom! I KNOW you have updates for us...


Yep- I’ve been chasing gremlins.

1) surging idle. I spent hours trying to figure out why the idle would surge up and down, up and down. I was convinced it had to be the EMS since everything on the motor is new, right? Yeah, no. Turns out the idle air control valve was stuck (common problem on WRX motors). Scott had sent a spare in one of the boxes of part. Cleaned it up, replaced it , good to go. Happy little motor.
2) but wait... why is the battery voltage so low (10-11 volts)? Poke around with the voltmeter, sure enough the alternator is only putting out 11 volts at the power stud. Needs a new alternator, right? $83 next day delivery from Amazon. Out with the old, in with the new.... and no change. (IMG:style_emoticons/default/WTF.gif)

Here’s a clue: I’m an idiot. Just like the 914, the WRX needs to have the eejit light circuit complete to excite the field, and make power (voltage). Installed the bulb for the gen light (thanks @mepstein ) and now have a perfectly good spare alternator if my cheapo Amazon unit craps out.

Picture of both culprits:

I also added a remote + post so I can jump/charge the battery without electrocuting myself. Probably won’t need this ever again, now that the alternator is working properly (see previous post)...

other misc (not picture worthy) tasks:
- installed Doug’s newly recovered seats. Very nice, but getting the tracks mounted to the seat bottoms was way more trouble than it needed to be.
- filled the coolant systems (engine and inter cooler).
- installed door handles (now with matching lock cylinders)
- installed various 914 Rubber seals
- AND thanks to @Spoke- installed a complete set of led lights- front and rear (picture worthy)

Picked up a pair of 3rd gen Miata side mirrors, which should be the last thing needed to get it inspected and road-legal, if not exactly road-worthy (missing door and rear glass and a bunch of other bits & pieces).

Miata mirrors have been done before, but does anyone have pictures & how-to advice? Holes will need to be drilled, and that's making me nervous.

I did first Gen Miatas on a build, but not the 3rd gen, should not be a huge issue. It has been so long since I built the car, I have forgot most of that build. (IMG:style_emoticons/default/confused24.gif) I remember getting them out of a Miata, and using the gasket to build a brake, and installing them in the doors. 3 holes to add, non-electric. The rest is a bit blurry. (IMG:style_emoticons/default/confused24.gif)

It’s been a while since I posted an update. Finally got it to pass inspection! They didn’t notice the missing rear and passenger door windows

Now I need help from the Subi-conversion guys...

Something in the engine bay was making a gawd-awful noise- like rocks in the laundry dryer. Turns out the turbo is shot. The shaft connecting the turbine and compressor wheels broke.

Now I need a decent (stock) turbo to get her running again. Any suggestions and recommendations where to buy? Or is this the time to upgrade?

Thanks,
Tom

Bummer on the turbo but you're making progress! Try the classifieds of NASIOC:

NASIOC engine stuff classifieds

You can post a WTB there also. Probably find a "take-off" stock turbo fairly easily.

I would say upgrade your engine was built to take added boast. (IMG:style_emoticons/default/happy11.gif)

You may be able to rebuild what you got. New Shaft Bearings, and seals, inpellers as long as the housing was not harmed, it should be good.

You reach out to Scott @Amenson he might have one sitting on a shelf right now, (IMG:style_emoticons/default/poke.gif) I am sure he is looking for a reason to upgrade, and off set his costs.

Thanks guys!

Scott is already aware- he’s got his motor out already. Could be a possibility... hmmmm.

Doug (PO) says the turbo was actually rebuilt before installation.

Rebuild is not likely with the shaft broken. I didn’t see a rebuild kit which includes the shaft & turbines. Also, the turbines were banging around in there so the housing is likely damaged.

A dangerous question: what else is needed to upgrade the turbo?

Ahhh, I will not be upgrading my turbo at this point. Primarily because the turbo plumbing will need to be modified to fit the new turbo...which is what will be the issue with your car as well. There may be some bolt in options but to make a noticeable improvements something bigger is needed. I think that it has a VF39, already an upgrade for the EJ20 and should get you pretty close to 300whp...especially if you enable flex fuel.

Tom, search for VF39 Cartridges, that gives you everything but the housings.

Correct. It was a VF39 out of an STI. Upgrade from the one that came with that motor. I tried finding the place that "rebuilt" it for me but their website is dead, so there's nothing we can do about that.

A new/used VF39 will bolt right on to the plumbing that's already been custom made.

well, it's been quite a while since my last update. Winter in New England.. no snow this year, but it has been too cold to work in my unheated garage.

I found a nice VF39 turbo from a local Subi tuner and finally installed it last weekend. Took a test drive this weekend. Who-weeee! I don't think the original turbo was ever working properly! Broke the tires loose every time in 1st. This this flies!

The rear window is not installed yet, so the spooling and snorting of the turbo and waste gate was... spine tingling to say the least.

Next up is to install all the glass (rear & passenger side) so I can take it out sooner.

I have an annoying clunk in my pass side strut. Driver side is fine. I can induce it by simply pushing down on that corner. Can't tell immediately what it is, but probably a rubber piece missing on that side or the nut needs tightening.
