My DIY build. help, thoughts?
 

Okay so I'm on my third sports car i guess you could say, a 91 one owner miata. With me being the second of course. I had a 1990 300zx and a 1990 Rx-7. Both non-turbo unfortunately. Ive been on this board and the miata forum board for a few months now doing research on turbocharging. I am just now, however, beginning to make some extra money to make this project feasible. I started putting together a parts list of things i would need to keep my engine safe and run a reasonable boost level, say 9-13 psi. I have performed all routine maintenance and a leakdown/compression check

T25 Turbo kit rated from 5-21 psi for 1.5-2.8L applications
Corksport FMIC
Custom Intercooler piping
Custom Downpipe
Flyin Miata Oil return lines
SS turbo manifold
1.8 injectors

My main question is about the electronics. What exactly do i need to control/monitor this system?

Thanks guys
Kyle

Megasquirt.

but you're not running 9-13psi on 1.8 injectors alone. either get bigger injectors or an AFPR(stupid decision since you'd have an MS and could just get bigger injectors)

When ive been searching thats all i found, I hate to ask this but is there anything cheaper? A programmable piggyback system perhaps?

cheaper? can you solder? under $300 for a fully programmable EMS

Emanage blue

So basically the emanage blue was what i was looking at originally. My only concern with that was once i have the kit installed can i take it and have it dyno tuned with no special tools of my own?

fuck that! I want to pay $300 for a Emanange blue that cant do half of what MS can do.

so megasquirt would be the only way to go really? shit thats like a good third of my budget lol

pretty sure ya would get the software with an emanage, any tunner with dyno n wideband probe would be able to do it. just got my megasquirt today, worth the money tho

If 300 dollars is 1/3rd of your budget, you should re-evaluate whether or not your really ready to take this plunge.

You really need to have a sitdown session and do some informed cost shopping. It sounds like your trying to do this on the cheap, but a corksport radiator, no mention of what kind of t25, and a FM oil return, but no feed line?

Haha no the emanage is 300 bucks, the cheapest ms i found was 700 bucks.

i agree

you could probably find it cheaper than 300 some members were selling EMB and EMU

So an emanage blue would be able to control larger injectors and be dyno tunable?

so you plan on boosing a miata for $900? good luck, you need fabrication skills, not advice

damn im late, lol

build your own MS, there are step by step instructions so you cant really screw up...if you have the time to do it
if not, pay someone to build you one...still cheap and very capable
do you have to pass emission? do you have ac?
if both are no, run it standalone...

You're implying that you're going to spend $700 on an MS. If that's the case, you're only looking at the MSPNP option. What I think Paul was suggesting was to build one yourself. Many in this forum have done that. If you're not an expert on electronics you could have someone else (read braineack or cjernigan) build one for you.

When I first turboed my car I asked cjernigan to build me one (I'm mechanically and electronically challenged :giggle:) and I couldn't be more satisfied with the results. Of course it did not cost me $700.

Also check the for sale section; once in a while someone sells one that will fit your needs.

BTW, I also agree with Paul's statement regarding the injector size; you're going to need bigger injectors!

Good luck with your project.

Lets break it down:

• T25 Turbo kit rated from 5-21 psi for 1.5-2.8L applications

WTF is this shit? Did you copy this from a turbo specialties kit? You have the option of any of the factory T25s (50-100ish) or the GT25xx series (out of your range probably).

• Corksport FMIC

If your really on a budget then why are you buying this? The chinacoolers are considerably cheaper, hell I'm selling my used one in the next week or so. (30 used- 100 new)

• Flyin Miata Oil return lines

Where is your feed line? If you source things out from JGStools, etc, you may find a better price the FM.

Since your original question was what do you need to control and monitor that system, I would include a WB sensor in your budget.

Of course, there are other parts missing; I don't see any WG or BOV in there for example.

yes

by the way let me give you some advice.
do a search before posting thing like this i am not trying to be an ass but most of the members that would jump on your ass about it are not online so you are very lucky. lol

but seriously familiarize yourself with the basics and than ask specifics.

Jeez, haha i searched day and night but that didnt tell me what to search for. The turbo has an internal wastegate and im getting an HKS SSQV for my BOV. My budget is 1600. For some reason everyone took the 300 dollar emanage and just tripled that. I guess the chinacooler would work. I may end up getting the turbo off an sr20
thanks for the help guys, i hope to have some pics before too long

break down...appx.
MS-400ish
used t25-100
oil feed return-100
mani and DP and 2.5" exhaust-700
IC-70ish
piping-100ish
injectors, 460's-100ish
WB 02-200ish
im sure i forgot a few things
you are under $2000, what was your budget?

buy smart aka used, lol
i got my HKS for $20
if you are a noob to life admit it and ask humbly for help, someone will empathize and walk you by the hand

the last price mentioned was $300. you then said that is 1/3 of your budget. so it seems to reason that one would triple the 1/3 to come up with the total. but i learned math back in the 70' & 80's before all this new fangled feel good fuzzy math stuff so maybe i'm out of touch.

paul how is that intake mani coming along? did you finish the gutting part? tested it yet?

i kinda lost interest after buying the BEGi Turbo intake manifold from MikeF85. I haven't installed that yet though and am still considering trying out the gutted manifold. Most likely I will get the BEGi mani installed just in time for the April 5th dyno day so who knows. Maybe later. Maybe on my other car. Maybe on Artie's car since he bought my spare 99 head.

damn i was looking forward to that. but keep us updated. now we can continue with the original thread. :)

i said the 700 for my ms was 1/3 not the 300 for the emanage. I am complete newbsauce to turbocharging, thats why i asked for help. I looked at all the other threads and couldnt find a couple answers which were answered here. thanks guys. this is a really good forum and i hope to get involved as my experience gets a little less on the n00b side.
:)

No shame in the BEGI S kit either, in your budget, one stop shopping, proven, and once you've gotten your feet wet, great base to learn from, easily upgradable.

DIY also takes some fabrication skills or at least a couple of tools. and opportunity to buy new tools :) What is your tool budget like?

Also without a good clutch ~$400.00 You'll be stuck around 150RWHP anyway..

To be fair, he could build a kit DIY for little money if he is patient and willing to do work himself.

I have my kit all together, minus installation and expected midpipe. I spent less than 1000.

I have all really nice quality parts, and Megasquirt managing everything. Gave me extra room in my budget to get an intake manifold...although I haven't exactly gotten a good clutch combo yet, but the turbo isn't going on till after I graduate in May anyway.
