Knowledge Conversion '94-'02
About 4 years ago I built a turbo setup for my '94 with a budget of about $2500. It was great fun and I learned a lot. I sold it.
Now I have a 2002 I bought with the intention of putting a LS1 in, but that project seems to be slipping away for lack of unlimited access to a garage. I have limited access to a shop where I think I could do a turbo build, so that is plan B I guess.
My question is what is going to be different this time?
Old car:
'94, came with a torsen
Budget of $2500
DIY standalone MS1
14b on home-made log manifold
2.5" exhaust
Cheap 6-puck ebay clutch
12 lb boost, 197whp on dyno-dynamics
460cc injectors
New car:
2002, 5spd, open rear end (must put LSD in rear end, but what are the options for '02?)
Budget of $5k to $6k
No idea what ECU to use, but I want a standalone
I haven't picket a turbo yet, but as small as I can to get 240whp.
Will be buying a manifold. Building one sucked and it always cracked.
3" exhaust, last time I was here Enthusa was what I drooled for.
Full-face clutch; I hated the old one.
550cc injectors.
I spent a LOT of time here while I built my '94, but then I sort of stopped and now I'm out of touch with what has changed in the last 2 years, and I never bothered to read much on the '02 cars in the first place.
I'm going to give it another week to find a garage for the V8 swap, but if I haven't found one I will start buying turbo parts. I'll be reading here to catch up in the mean time, but where should I start? For somebody who knew so much, I feel like such a noob!
Thanks in advance!

Here's my .02:
-torsen will work on the 02 just like your 94
-ms3 if you can put it together, ms2 diypnp if you cant
-2560 or 2860
-begi log or fm log. both are similar priced and both are very reliable
-tons of options but if you can weld I'd do it myself
-fm happy meal or act hdss
-tons of options
Sounds like you're aiming for a VERY basic and simple setup and that's a good thing.
It should be very easy to piece together and run trouble free.

I would say MS3 with MS3x. It will have VVT support sometime in the next few months. Y8s still has connectors for the ECU so Brain can build you a PNP kit.
For the cluctch go with an FM1.
GT2560 for the turbo and you will be golden.
Manifold and DP are where you now have choices. With the budget you have, no reason you have to go with FM or Begi. You can probably afford an artech or absurdflow if you want them.

I am bored at working and waiting for some large files to copy so I have done some price estimates.
MS3 + MS3X + wiring - $558 from DiyAutoTune
LC-1 - $200 anywhere
FM1 clutch - $350 from FM
Enthuza 3" Exhaust - $300? from enthuza
Used GT2560 $500
Intercooler - $100 from ebay
Piping - $150 from ebay
Oil and Water lines from Begi or one of the other vendors on here - $200 high estimate
550cc RX-7 Injectors - $150
So far that is about $2500 and leaves you just needing a Manifold and DP and BOV. Also prices are just some quick rough estimates, can probably find better deals on a lot of the stuff.

Thanks for the help, guys! I had forgotten how awesome this place is.
18psi, your car looks awesome, and quite similar to mine:
Untitled by skidude108
Here it is doing some off-roading this last summer.
I will have to read a bunch on this MS3 thing, since I don't even know what the MS3X is. Unless it's a lot harder than the MS1, I will probably plan to build my own MS, since that seemed to work pretty well for me before. This is a stupid question, but I can't go poking around since my car is currently buried in a snow bank (literally, completely buried), but where IS the ECU in this car? I didn't see it behind the seat when I looked once this summer. At least there was no bulge in the carpet like my '94 had.
Time for some reading! And maybe a new sig pic or something.

ECU should be above the clutch pedal.
MS3 is the newest version of MS. It was released about a year ago and just now at a stable code base. The MS3x is an adapter board that plugs in and provides a good amount of additional features. More or less you can have sequential fuel and spark, along with built in EBC, and sometime soon VVT control. If you build you old MS1, you can build an MS3. Basically you build the MS the same, but instead of plugging in the MS1 cpu you plugs in the MS3 daughter board.

Sounds reasonable. I will plan to build my own MS3 then, and I assume it fits in the stock ECU location, or somewhere close by?
I remember reading back in the day that MS1 didn't work well on the NBs, and MS2 could be made to work with a bunch of effort, but it sounds like MS3 is pretty much good-to-go.

shuiend is IMing me and asking me questions so he can post the answers here haha
not quite PnP since you have to wire to your COPs and boost and whatever else you need but I connectorized all the non miata harness wires:
The white connector in the middle is the 01 ECU connector.
There are several mods done to the MS3X to make it miata friendly but they're not that hard.

Here's my .02:
-torsen will work on the 02 just like your 94
-ms3 if you can put it together, ms2 diypnp if you cant
-2560 or 2860
-begi log or fm log. both are similar priced and both are very reliable
-tons of options but if you can weld I'd do it myself
-fm happy meal or act hdss
-tons of options
Sounds like you're aiming for a VERY basic and simple setup and that's a good thing.
It should be very easy to piece together and run trouble free.

I would do the MS3 for sure, but you might also want to look into an AEM. Everybody already has it going with VVT.

I like that PnP harness, and I will buy one from you as soon as I commit to this!
Is there a place where all this MS3 info lives? Like what mods need to be made and all that fun stuff? When I built my MS1 I loved having that DIY thread about which mods to do. I know a little better now about what I'm doing but it's still been a while.
I've been searching for a comprehensive MS3 thread but I'm not finding much. I've only made it back about 3 pages in the search results for "MS3" though. I'll get there.

And while I'm asking stupid questions, if I want a Torsen in my '02, what is the easiest/cheapest way to do it? Do I buy a whole used pumpkin and swap the whole thing or buy just the torsen part and add it in, or what?
#16
Just buy the torsen.

Be forewarned that parts alone for my harness are like $75, but it is pretty awesome.
...
As far as comprehensive MS3 threads, there are none. I basically started mine from scratch since I had zero experience with MS1, MS2, or anything in between.
I created a huge spreadsheet that spells out every MS3X pin, every Miata ECU pin, and all of the additional I/O just to get a handle on it all. I need to add a few details on the custom mods I did but that part is pretty easy to figure out. I made it essentially the maximum input and output option so I could do lots of different stuff.

For that budget and the super easy option, I'd just buy a BegiS3 kit and have one of the guys here build you an MSPNP... be done with it. The GT2560 will be enough to get you 240whp on an '02 with even a marginal tune. Within your budget, you've got enough left to do a 3" exhaust and stuff like a full fluid swap, fuel filter, locking hardware, injectors, fuel pump, etc and a few dozen other niceties to help you achieve that "set it and forget it" car we're all looking for.

That harness is the only one that exists but I can possibly make another. I have the ECU connectors and plenty of wire.

As for MS3 threads, it sounds like I should start reading now if I am to have any hope of making it work. I assume the MS forum is the place for that?
Ok. I will keep my eyes peeled for one of those. They're on ebay for cheap but they have to come from Japan so there must be some on this continent for sale used.
Thanks for the help guys! I learned a lot on my first build, but the most important stuff I learned was what NOT to do on this one.
