So I have been reading here, else where and applying prior knowledge as to just how I want to do this.

I figured after reading and going through everything I would post here and get some opinions from those with experience.

I do not have a WHP Goal honestly, just looking to have fun and be reliable. With that said I already have two requirements to ensure this, Wideband (Already purchased) and Megasquirt 2 PNP (I have experience with the KL Motors and the Version one processor so I should be able to pick up and not do to badly with the Version 2 Processor).

The vehicle in question is a 2000 Miata and Emissions are not an issue for me thankfully.

My plans are as follows:

• Megasquirt V2 PNP (Missed the Bulk Buy, registered just a little to late so I am on the waiting list)
• Walbro 255 Fuel Pump
• Lighter Flywheel (I know this is not the norm but it is my pref for my driving style)
• KL Clutch Disk, Probably a Spec Stage 2 Disk
• It seems most keep the Miata Pressure Plate so I was going to look for an upgraded one to use if I can find one.
• eBay Turbo Manifold that I will make support brackets for myself as well as check the welds.
• Front Mount Intercooler

I have debated doing a Supercharger like the Eaton M62 with the Clutch (Seen on the C230's) but I want to try a turbo this time.

I also already have 2 sets of injectors:
RC550cc Injectors
WRX 820cc Just cleaned and flow benched injectors but the connectors are on the side so I might have to make a custom fuel rail for these.

I will be running E85 90% of the time, its not hard to get my hands on here and obviously has great results for the price.
However using Megasquirt and running lower boost I will be able to go to 91 should I need to for any reason.

Now I do not feel the 550cc Injectors will be able to handle E85 + Boost so I will probably sell those after getting the rest of the kit ready. (I am going to run E85 NA for a while to get used to tuning for E85 esp since doing it NA will mean its pretty safe in regards to me blowing something up, should be good practice)

I am not looking to build the motor so obviously were not looking to break 300whp. Maybe later on but honestly I find my next goal after this will be going back to a KL unless this motor boosted just blows me away.

While building it I will have access to a block to mock most of this up on and another oil pan so when I am ready to go it will be my goal to be a weekend swap out and make any exhaust modifications I have to that were not forseen while building.

I however have not settled on the perfect turbo yet. I would love users advice and I have seen some love for the FM turbo that I am now spacing on the number I will go snag it from the website again.
Advice is very welcome.

Also on cooling I want to do it right and have been looking at the reroute modification as it seems to be a more reliable and smarter choice then just going after the radiator.
I think I can do most of it myself but I am still looking at information on that closely.

The goal for completing this build is 3 to 4 months from now, barring any unforeseen issues.

I also have a more random question to go with this if anyone knows,
I am looking to swap in the 6 speed rear diff. I would like the longer gears for top speed runs with the Vettes from time to time, nothing grand but just for fun at times.
I am worried however as to how the Gauge Cluster gets its Speed Readings and if that can be adjusted easily like say with the GM LSx Setups where we just told the PCM this is the Gear Ratio and Tire size and it handled it.

Thanks everyone and I hope my post is not too Noob for those experienced members here.

hmmmmm, i think sombody on here is selling a GT2871rs which i would say buy that turbo! i think he is selling it for like 750 which is a good deal!

put a 6 speed in that bitch along with a 3.9 torsen

**** the speedo

i hope you dont have emmisions where you live or have some way around it

dont just do a reroute, i say get a rad too

550cc injectors + E85 = teh suck

you can get close to 300 reliably

screw WRX injectors and get somthing that is as close to PNP as you can get

**** egay manifolds (Absurdflow/ARTech or bust)

supercharges are for ****

have a nice day!

Speedo is controlled by the speed sensor on the transmission, all you have to do is plug the sensor from whatever ratio diff you're using into it and it will work.

I do not want a six speed as it defeats the purpose of going to the longer gears plus 5 speeds are cheap if I start breaking them lol.

Using Megasquirt I don't think it matters what injector I use, it will drive them and connectors are dirt cheap.

Emissions are not an issue for me, I am evil I never runs cats etc. But with Megasquirt this will be the first time I may actually see how it fairs. They will not be able to do the OBD Read so they will have to run the sniffer and its not like Cali here they do not care that you mod your vehicle so long as it passes.
However for the day when we do care I still have the vehicle registered where it does not have to pass anyway.

Saedrin, thank you for that information so all I have to do is pull the sensor from the 6 speed tranny and swap it out then I am golden. Good to know I will snag one of those too.
Huge Help!

what i is saying bout them injectors is get somthigh that you wont have to make a custom fuel rail for. work smarter not harder!

MS and injectors have nothing to do with being PNP. it has to do with simply pluging into the factor harness or having a set with pig tails so you can easily splice into the factory harness!

i know that on the MSPNPs you have to run high impedance injectors or run a resistor pack, but that those are MS-I. idk about MS-II and all the other **** out there.

6-speed and 3.9 or 3.63 gears = sex (hmm where is that top speed calculator on the interwebz)

Making the Rail is not a huge ordeal since I have quite a few machinists for friends. You would be surprised what a bottle of Liqueur gets you sometimes. We have done it a few times, I actually already paid for a rail for my 3SGTE MR2 Build and never went through with it so the favor is still on the table but I am a nice guy so it will get him another bottle of Patron.

I am sure there are other injectors that fit too but getting up to those flow rates WRX injectors are cheap (No more than 150 for 4) and since I have the means to keep it cheap and I already own a freshly cleaned and benched set might as well put them to use.
I will make the connector that doesn't bother me a little wire and solder work only kill you when your working on someone else's nightmare.

Getting injectors that fit bigger than 550cc will probably cost me more or the same amount if someone is selling a used set cheaply considering the options available to me. But for others I agree it probably would be easier to go the other direction.

im speaking out my *** here! but from what i have gatherd in the past 550 will support about 275-300. (dont quote me on that though) a couple of locals around me were seeing 80-90% duty cycles on their 550s sub 300hp, and if you are gonna be running E85 you will need at least 30% more fuel, there for the need in a larger injector.

now that you say you have teh hookup with some machineing work. knock yourself out with the WRX injectors. just find out if they are low impedance or high impedance and check the specks of your EMS to find out if you can run them with or without a resistor pack!

there are quite a few guys on here that are running E85. go to the search function at the top of the screen and type in 18psi and search for his build thead! < good info in there!

His build is very nice, he even offered to sell me his Adaptronic (SP?) but I want MS and as for the Resistor pack MS can handle either so its safe there.

Yes 550cc should be fine for 91 but E85 as I stated in the first post, just not going to handle it safely.
But 550cc +30% basically comes out too = 715cc so 820cc should be good to go for my goals. (My math is probably not 110% on but should be quite close and I did look into others running around 300whp 550cc's seem to be the choice some use lower but I believe they are cranking up the FP)

as far as the MS i only know a few things about it and the MSPNP(MS-I) i think only supports high imp. i havnt looked into other options from DIY and what the capabilities of the newer units are. i suck at math but the above sounds right

good info for myself to know though! lol i need to catch up on all teh MS ****.

I started with MS Version I on the Mazda KL's its a fun system, but I have never used the MS Version II however it seems to have some really nice feature changes so I am looking forward to jumping in but thats why I want to start with the 550cc and E85 on my motor NA so that I hopefully don't blow anything up while I am getting used to the changes and advancements.

Definitely nice to shoot things around with you WonTon, although your user name is making me hungry lol. Always nice to chat with a fellow enthusiast.

WonTon

iTrader: (17)

thats a first, i have never had sombody say my SN is makin them hungry! lol

but yeah, getting your car running on the standalone is a good idea, less **** to deal with and alows you to make an easy transfer from NA to FI with less hicups!

lemme see if i can find that turbo i was talkin bout that for sale on here!

If I get my hands on a 3.63 that would be great but for now in all the miata's parted out around here 3.9 is easier to get my hands on and 6 speeds are still 600-800 a pop vs 150-300 a pop for 5 speeds.

If this was an all out build maybe but obviously this is a fun but budgeted build because before I put a ton of money into this vehicle I am going to decide if the 1.8L is worth my time or if I will just sell my whole setup and move to a KLG4 and a Turbo Kit on that. (Esp considering how cheap they are and how well they hold up to boost)

Any reason for doing this? I've never heard of using a non-Miata clutch disk. Cheaper? Or just have one leftover?

Cross

iTrader: (4)

Its a bigger clutch disc stock and has provided solid results to others for a much cheaper price. With aftermarket discs being easy to come by for the KL I figured I would go that route.
