Greeting from Issaquah Washington!
 

Hey all!
I joined up a while ago to read, learn and plan my build. I figured it is time to say hello!

I've got a 1992 1.6L :dealwithit:

First thing i bought for the project was a MSPNP2, and got the car running. Then i deleted the AFM (stupid thing) and bought some 610cc injectors, and started re-tuning the fuel tables.

(Also i recently upgraded tuner studio and started using auto tune...love it!)

Still a ways out before i fit up the turbo, i'd like to re-do the whole exhaust anyways to 3 inch as well as some body work and a respray.

Anyways, i look forward to learning more and eventually having a turbo Miata!

Welcome. Sounds like you're on the right track. There are a good number of us in Portland and a few up in your area too.

Besusjesus, congrats on signing up at the best site on the web!

Thanks guys!
Aidandj - do alot of you do AutoX or track days down there? eventually i want to get into that. I know we've got some events in the Seattle area.

The weather was merciful after work last night, so i took the car out for a bit to do some auto tuning, boy it is running rich! Idle is a steady 14.7 @ 950 rpm currently but i need to keep working on everything above 3K RPM. Baby steps, can't wait till summer when its warmer and the sun stays up longer!

A decent amount of us do track days. I do some auto-x but not as often.

Updates Time!

Car is running pretty well, still lots to do!
recent acquired parts include:
E-Bay special cast manifold (Making a custom down pipe)
1.6 protege valve cover, cause why not?
Waiting to find the elusive t3 churbo everyone seems to run (MK Turbo kit?), sounds like they are out of stock with no ETA...in the mean time i did find this guy, but i'm not sure on the brand...it seems to be hit or miss, but i read the same about a cx racing one...:Since i am close to sticking the turbo bits on, i may just pick one up and be a guinea pig.
For Turbo Charger T3 Internal Wastegate com 42 A R 45 Trim 48A R | eBay

Oil pan is drilled and tapped, plugged for now.
Next up on the list it a full 3 inch exhaust with V-Bands to make it easy to swap in my turbo/down pipe.

One thing i noticed during tuning, my injectors are very, very loud..they are the flow force i got brand new from nigelt..everything appears to be working, but i can hear them very clearly from inside the car..and yes, i verified no exhaust leak and it is not lifter tick. Is this normal for these?

Also! i have a problem, a Miata problem...my DD was getting old a costing more than buying a new car...so i did what any normal Miata owner would do... i went out and got another one! I picked myself up a 2016 ND sport, yes a sport.. I did not want a 7 inch touch screen and buttons where my shifting arm rests! First thing i did was add a Goodwin Racing muffler to wake up the sound, next i will be getting some lowering springs - no i am not slamming it, just want to lower a little for a better look.

I am about 95% sure that is the correct turbo. I have not got confirmation on the phone, but the specs to match exactly the last 11 I bought from them according to eBay, and this is about the time frame I was told they would be getting more.

Nice, thanks! I'll pick one up and we'll see! They don't list what the waste gate is set to..i assume around 7-8 for these smaller T3s?

some of them are loud, work just fine. you'll be fine
this is really cool :likecat:

Good to know, they tick pretty good but i haven't had trouble with them..I'm thinking about deleting the air valve on the intake manifold, the Protege valve cover i got has a plug already in place where i would run the hose to...think i'll just keep it plugged..

Turbo is on the way, should be here by next Thurs-Fri..I'll take some pictures for you, maybe these are a match for what you run in your kit.

PNW FTW!!!

Hey. Pretty new myself. I'm up in snohomish.

I typically avoid pointing people towards club roadster, but come join us in the PDX lounge if you haven't already.

We will have to do a meet/cruise with locals me thinks. I see that you have a brg miata, looking for a brg hardtop?

Yeah, shoot me a PM if you want to tag up.

Talk to me about the hard top. Any parts you're after?

It's a brg OEM hardtop i bought 3 years ago for $1100, defrost was working last year but i haven't used it in a while..toying with the idea of posting it for sale. An extra $1000 would go a long way in my project, and i will only be driving this car in sunny weather so i really don't need a hardtop anymore..but i'm not 100% i want to give it up either.

Turbo came in, looks to be a match to what you have for the MKTurbo kit.

Pull off the shiny compressor housing and measure the compressor wheel. Then I can tell you if it matches or not.

Sure thing, i need to pick myself up a digital caliper - will do that today or tomorrow.

HarborFreight digital calipers FTW. At least they are FTW for for measuring things like this where you don't have to have perfect accuracy.

Yeah, they have one in store for $20, and there is a HarborFreight less then 30 minutes from me.

Harbor Freight Tools Coupon Database - Free coupons, 25 percent off coupons, 20 percent off coupons, No Purchase Required coupons, toolbox coupons

You should be able to get it for close to $10 or so.

Nice! much appreciated!

Hello,

PNW local here. welcome to the forum

Measurements are: 42.5 and 60

Started up the car to take it for a drive and do some tuning while i wait on a few parts to come in...there is a horrible noise coming from what sounds like the timing belt almost as if it was over tightened,it was done last year and i haven't heard this noise before and it gets worse when i rev the engine. Guess i'll be doing a timing belt as well now.

Hmm. Never heard of a timing belt suddenly making a horrible noise. That doesn't make much sense. Is it just a squealing belt? What kind of noise is it?

It really just sounds like an over tight timing belt. i'll have to get a video when i can, the tensioners look pretty beat up, i took all other belts off the car to see if it was another belt. I may try and break loose the belt tensioner and reset it.

Huh. Weird. Ok, good luck man.

Think i'll have to start a build thread..The timing belt noise was the belt rubbing on one of the covers, i must have smashed it when i was working near it.oops.

Major confidence boost with the car last night, i drove it nicely to the gas station letting the engine warm up, filled her up and went out for the furthest drive the car has had in over a year! Cruises great, still tuning for wide open throttle but i added a bunch of fuel up top towards 80+kpa to start a bit rich..i think i need to work on me Accel enrich, at idle if i touch the throttle it leans out and then is fine after that 1-2 seconds.
Also need to work on my idle afr, after the car warms up to 190ish coolant temp it starts to idle around 700rpm and at 15-15.5 afr. Auto tune doesn't seem to be correcting that, so i'll do it manually.
One thing i noticed is the car feels so slow, i keep thinking to myself "has it always been this slow, and my ND has just spoiled me?!". It does pull a bit to the right and i can hear the brake on that side, lots of rust build up on that rotor so i'm thinking that isn't helping the car move forward, new brakes time!

i can't wait to get this thing resprayed, it is currently about 4 different shades of white and looks horrible. My buddy has an 87 Nissan 200sx with the 3.0L V6 option. It was stolen and recovered but badly beat up, they tried to respray it with cans and ruined the paint. We are doing the body work on the weekends and will be respraying it, maybe ill do the NA Miata at the same time.

You shouldn't autotune your idle. Enable the idle VE table and tune it manually. There are a lot of threads on tuning idle.

Read up on tuning my idle, got that sorted out pretty decently, i also worked on my AE and that seems to be good. Now when i put the car into any gear with the clutch in the RPMs rise to about 2000..i am not sure what i did, but i need to read some more:)

Well, still chasing down this weird idle jump. If i'm in neutral everything is fine, but with the clutch pedal pressed down and trans in gear the idle jumps to around 2000. Not sure what to think and can't seem to find any solid answers..may just restore an older tune before the issue.
