I didn't want to be sloshed when I came in the house on a Monday night.
So it looks like i've gotta start compiling a boost parts list for the Miata. I finally bought a turbo for it.
I was talking to James last night and he gave me a pretty good idea, but I think the things i'll need to figure out is what kind of injectors I need to run and if I need to make any other changes. James told me where to get the tune, i've found a cast iron manifold for the turbo already, and i'll need to figure out all of the piping.
I figure I need to pick your brain some too though Ray, since your car is almost exactly the same as mine. I'm going to be using a Subaru WRX turbo(TD05) and i'd like to shoot for 8-10psi for boost. It probably won't get installed this year, but I plan to acquire the parts this year.
Anytime man, anytime. The TD05 is set at 8psi for the internal wastegate. It spools pretty quickly, but I've seen faster in regards to initial spool. Either way, it won't disappoint you and there isn't any lag once its at full boost and you're changing gears.
Here is what I have so far
- 1.6l with approx 160,000 miles at time of install. 180k+ and climbing.
- TD05 turbo, 8psi
- Innovate Wideband 02
- 2002 purple top Miata injectors 265cc- courtesy of James. While running at 8 lbs, I still have room for more with those injectors and the stock fuel pump. I just need a better manual boost controller than can give me 10lbs and not create boost spikes. If you want to go install one, spend the money for a good one. 200hp is definitely within reach.
- Generic FMIC
- Piping kit from Ebay. Assortment of other couplers from siliconintakes.com They have EVERYTHING from connection couplers, increasers, reducers, etc.
- ACT ZM2-HDSS clutch- don't skimp on the clutch, you will
cause a stock clutch to slip as soon as the transmission sees any boost.
- New stock copper radiator without plastic end tanks- a b**** to find though, so just buy a good aftermarket one. A radiator isn't needed, but I'd suggest it. FWIW, I haven't bothered with the coolant reroute. I haven't seen a definitive yes or no in regards to performance, so I'm probably never going to bother.
- MS2PNP9093, professional tune. MS2 or MS3 are both excellent.

I was thinking about going with RX7 injectors(550cc) or more likely 1.8L Miata injectors. If I upgrade the MAF, i'll probably just use James's 1.8L MAF he still has but I may be able to get by with the stock one.
I'm glad to hear I can go with the cheap piping, because that's what i've been looking at.
I'm not aiming for a specific HP goal, but i'd like to be at 200hp and any more will be a bonus.
Now, what about ECU's and stuff? Do I just go for a Megasquirt?
Spend the money on a stand alone and a tune. Worth every penny. RX7 injectors are fine, and they're definitely safe. I was just on a budget build and James' old ones are working out just fine and required absolutely no modification to the connectors or pigtails- plug and play. Like I said, I still have room for more. As for the hardware- I'm a Megasquirt fan boy. Complete control without guessing is the key to reliable power. Megasquirt comes two ways: PNP or DIY.
I sucked it up and bought a PNP since I wanted to remove it from the equation if I ever had a problem. That, and I SUCK at soldering.
However, as a cost effective option, a user named Reverent on miataturbo.net will build you the DIY MS for less than the cost of a PNP.
If you do go MS, you will not need an MAF since you'll be converting to IAT. The sensor is cheap, $20-30 and defeats the need for an MAF.
You'll also need a blow off valve. I got a stock BOV from an Eagle Talon and let it blow to the atmosphere to scare small children and surprise Bros with WRX's. Flyin Miata sells an elbow that bends down off your throttle body and includes a bung for the IAT sensor, a connection for one of the intake vacuum hoses and a place for the BOV. Its part # 27 in the diagram in their website:

I also used that exact install instruction kit the day I bolted all my stuff up.
You can also buy those one piece intercooler pipes from them, but without the FM turbo, I didn't want to buy them and opted to make my own using a generic kit and a Sawzall. Also check to see if the turbo needs a J pipe or if the inlet will mate to a coupler. Having a new exhaust manifold gasket wouldn't hurt since you'll be in there anyway.
Don't forget about your downpipe. If FM does't have one that bolts up, this guy names Sturovo over seas probably has something that will bolt up perfectly. His work was rough to begin with, but looks amazing now. He could be sure to weld in an 02 sensor bung for you, too.

One last thing- don't buy anything, and I mean ANYTHING from Bell Engineering. f*** that s*** excuse of a company. FM is the best, hands down. Even if you only buy a couple of things from them, their customer service and advice is open to all of their customers, big or small. Specifically, Jeremy helped me out quite a bit when I had a question and couldn't reach someone with turbo knowledge.
Oh- and if the turbo doesn't come with oil line fittings and coolant line banjo bolts,etc, I can likely help you out with buying the right hardware the first time so you don't have to trial and error like I did.
Finally (I know I said last thing like 3 topics ago) don't forget to get a oil feed and drain hoses as well as a fitting for the drain hose from Flyin Miata. You can borrow my tap so long as you mail it back- don't buy that. You can use fuel hose or coolant hose for the coolant lines to/from the turbo. Stock up on a collection of various sized clamps, too. The less trips to the parts store, the better.
Print these pages out!
Or- better yet, Copy and Paste the info into a new thread in the Others forum as a check list for yourself. If you shoot me your email addy, I'll send you my turbo spreadsheet. Its simple, but works.
