Noob that is beginning aspiration conversion.
 

Hello Turbo people. My name is Dan, with one n.

I am currently supercharged, and am beginning my turbo conversion. I plan to begin by Megasquirting my setup as is. Once I get it tuned, I plan to add some larger injectors and WI. Hopefully by then, a the Trackspeed kit is available. If not, probably an Absurdflow mani and EFR turbo.

I am 29 years old and married to an amazing woman who supports my car habits. I served 6 years in the Navy, as a structural mechanic. I've been out for 4 years and am a sales manager. Love chatting cars, and look forward to learning a ton from you guys.

Hello, Dan. Welcome to MT.

Thank you for having a well written and well spaced opening post with reasonable goals. It is very refreshing.

Welcome!

It was late last night to dig up pictures, so here are a few (I know it looks the same as everyone else's car / no originality).

I didn't get flamed on my original post, so hopefully this might stir up 18psi or hustler to say something hateful. Then I know that I have arrived, and am ready to post in a real thread...

Its not rape if you're willing.
I'm not hard if you're lubed, don't clench, and don't scream.

Nice car

Is that color black cherry mica? That's my favorite Miata color. Nice car and welcome!

I believe in 2000 they called it Mahogany Mica. Although, I am corrected quite often. I drive a "purple" Miata.

Thanks everyone for your kindness. It is a very fun car.

I originally wanted a Miata as a track / AutoX car. When I bought it, I was driving an E46 M3 as my DD, but soon fell victim to the Miata. There was no going back.

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

Thanks for the warm welcomes! I've actually just been creeping on you guys for the past 3 years -- quietly learning.

As I've decided to go the turbo route, I am lurking around (getting my post count up to acceptable levels) waiting on someone to sell some stuff I need in classifieds.

...then I am going to sell my supercharger (to a noob) in your classifieds for the irony.

Glad to see this thing getting a proper setup. Very very clean car you have there, i don't think anyone is going to hate on you here.

Edit: How many powercards are you running?

Not enough.

I am ready to start tinkering with a MS. Just so many options. Hard to pull the trigger. Car runs great now. Since I don't know any tuners local, I just want to make sure I am confidant tuning it to a good safe / DD tune. Lots of reading...

ms2e
done

That's the model that require assembly correct?

I think I might be better with plug and play. I broke an iPhone taking apart and putting back together...

Nah the 'e' stands for Enhanced. That's Reverant's version, which is plug and play.

Will I be able to run 5th injector off the MS? I was hoping to tune in baby steps. Would I be better off just upgrading to 550cc injectors when installing MS, or installing WI?

:rofl:

You probably could, but it might be safer to take the belt off or wire the bypass open until you get the hang of it. At least that is my plan, learn NA on stock injectors, then install larger ones, then turbo.

Anyone tuners around here or Dallas area that could install / tune the MS2e for me?

If you seriously try to tune a 5 injector setup with MS I'm going to petition to ban you

Stop being a homo and do it right. BTW there's plenty of tuners in Dallas

Yes, his name is Dan and he lives in Little Rock.

talkin' about you, bro

Larger injectors are usually installed in conjunction with the MS. Although we suggest installing and tuning the MS before going to forced induction, I don't think we'd ever suggest keeping your bandaid 5th injector and/or auxiliary fuel pressure regulator after going MS. Just install the larger injectors at the same time.

Remove stupidcharger.
Acquire MS2e (or ms3x if you wanna be baller)
Tune the car n/a and learn MS.

Install turbo and supporting mods
?????
Finally get vagina

Why not remove belt, tune NA, and after solid tune, reinstall belt and tune FI while I am acquiring my turbo and supporting mods?

That bad idea?

Not too bad. Or that and when you're ready for f/i just drop in better injectors and dump the 5th injector failaidz in the trash where it belongs

Question: (I know you will have jokes, and I look forward to them and the memes, but answer the question too.)

Is water / meth injection considered a bandaid? It seems like cooling the intake charge would be better than not, right? I could very well be wrong. Look forward to being intelligently informed :)

Its not a bandaid unless its used as a bandaid (ie: to compensate for lack of fuel).

If you have proper fueling and use the w/i for its heat extraction properties (the way its intended to be used) then its pretty sweet. It should never replace an intercooler (no matter what some geniuses will try to tell you) but works fantastic in addition to one

Is mine compensating for lack of fuel?

Without using the 5th injector, I can run 11.5:1afr at the redline in 5th (6speed) with my 305cc. Since I can fuel without the 5th, would it not technically be beneficial?

(Once again, I am honestly learning.)

Ditch the 5th and run it on the 305's then. But 1st get MS and unload the pansycards on another n00b

And while I got you guys, if you were building a turbo kit today, what parts would you buy?

250whp daily driver (will build in the next few years or when engine goes -- whichever comes sooner). Got a budget, but its not a big deal. Rather save if its expensive and have a better setup at the end of the day.

Your going to hate me, and I guess I won't ask again.

I am not a chemist, and won't debate any logical explanation, because your most likely right, but if its not required for fueling, and my exhaust temps are cooler using it, why should I ditch it?

As you know, I'm going turbo. It just seems like an extra safeguard at this point. Once again, I am wrong all the time...

you're getting awful close to asking stupid questions again, since that's one of the most beaten to death "lists" anyone has ever asked on this forum.

log mani
gt2560
3" exhaust
460+ injectors
MS
wideband
fmic

that's about it. you can probably start off with a begi "starter" and MS and add on the extras as your wallet permits

Its an extra point of failure/weak link. And completely un-necessary. Its 80's technology. If you don't need it, don't use it. use the KISS principle (keep it simple stupid). all the extra wiring, fuel line, fittings, etc required to run the 5th injector is just stupid and pointless. Its 2013 and we don't drive Buicks

The "lower exhaust temps" arguments is an asinine argument used by a gigantic idiot by the name of Tom @ FFS and his minions. Anyone still using a 5th injector or "e-cool" is considered retarded on MT.net. Seriously. We wont' even waste time helping you if you listen to him and his stupid ideas/logic

Thank you for explanation.

Also, my plan was EFR / Absurdflow or ARtech. Is there not compelling reason to use custom fabricated manifolds or higher end turbos on stock motor?

Possibly 250 is 250, and I should save money for building motor?

hahaha if you have the money to chuck at an ABSURD/EFR setup I would be the last person in the world to tell you not to do it. you'd definitely need a built engine with something like that though. they will sodomize those stock rods with the quickness

Yeah. Reason I asked about the setup was not because I don't know a "basic good" setup, but since my plan was to build down the road, it seems like you'd save money (break even) by not buying new turbo and mani to match your build. Can't you just run 12-14psi (whatever equates to around 250whp) on a 6258 safely on stock motor and turn up boost after build?

Correct if wrong (or if I am being dum noob).

its very potent and spools very fast. meaning if you put enough load on it low enough in teh rev range it has a good chance of snapping a rod even at low pressure levels like 9-10psi

At 12-14 I fully expect an EFR to overpower the stock engine on the 1st pull

So the answer is you probably CAN run that on stock engine, but will probably end up breaking things anyway.

:rofl::rofl::rofl:

So no one here is running EFR turbo on stock motor? Sounds like we need a guinea pig.

Actually, the first guy to post here with an EFR had a stock motor. It was, literally, the shittiest setup you could imagine, but with a baller EFR. Still made like 270whp without breaking a sweat.

Edit: Read https://www.miataturbo.net/diy-turbo...-6258-a-56871/

Edit2: Ari (99MX5) ran with a stock motor. Vented block status with the quickness.

We like guinea pigs that try baller parts around here.

Do it

I just finished reading that original post. Your quick. Wonder if there is room for a decent manifold while maintaining AC and PS.

So far manifold options for that sucker are few. Very few.

Welcome danduv, to the best site on the net!

If you want a ramhorn style manifold that will work with an EFR and retain AC/PS talk to abe at ARTech. I know he has a top mount that will work and I am fairly positive he has a bottom mount that will work too. I know I asked him about it in another thread and he said he would have to test it with an EFR to make sure but he said it should work.

FrankB is also putting an EFR on his stock motor and he went out and got the low boost wastegate which is 6psi, I believe, to be sure he did not vent the block. I for one say buy once. Always try to modify with your absolute end goal in mind so you don't have to redo your setup every time you get the itch for more power.

Exactly what I was thinking.

Any benefits to top or bottom mount? I think I am going this route.

I don't know what any of these acronyms mean - log mani, MS, fmic, etc – but I have enjoyed reading this thread very much. I find it amusing that this turbo thing has a complete language all its own and I am glad you guys know what it is!

I’m a bit on the old school side and never got past V8…:noob:

log mani = cast turbo manifold, ms = megasquirt, fmic = front mount intercooler.

I looked through your build, looks good man.

Bottom mounts are better for flow because of the downpipe path not having so many hard bends. The packaging for bottom mounts usually makes retaining AC/PS very difficult. They are also harder to work on.

Top mount manifolds sacrifice optimal flow for ease of packaging and maintenance. The turbo is very easy to get to in the engine bay and is clear from the AC/PS. This also places the turbo near some items in the engine bay that need to be protected from the heat including but not limited to the dipstick, fluid lines/resevoirs, etc.

Generally speaking, would it to safe to say a good top mount would still flow better than log?

For sure. Leaps and bounds better. They still flow very well, it is just not as optimal as a bottom mount. Most people around here with ramhorn manifolds run top mount for ease of packaging and access.
