All I ever read is V8 turbo stuff in this forum, which isn't a bad thing, but I'm eager to learn and share experience with those that are into the 2.3 turbo stuff as well.
I'm getting ready to put a turbo on my 93 coupe, 2.3, 5 speed. It's already got a turbo coupe rear axle, 4 wheel disc brakes, V8 front spindles and brakes, 17"wheels, billet shifter, spec stage 3 clutch, flowmaster cat back with LX tips, off road single to dual front pipe. I did this to see if it would improve fuel economy and allow me to put my wideband O2 in it when I tune it.
My project is going in stages, I'm almost done with the first phase, going on to the second phase now which is opening the computer and putting the chip in and start messing with the n/a tune. Once I get the best power and mileage out of it as is, then the turbo goes on.
Turbo kit will be mostly from Stinger, but I already have a 57 trim turbo. I'm also going a little different route using the stock maf electronics from the 93 with a ProM meter with a big air calibration on it for blow through. I'm just wanting to go at it with a little different approach to see how it works out. Stock engine for now, using their fmic kit too. Going to start with some 36 lb injectors and go up from there. Also have a GSS340 pump going into it too.

Anyone else out there?

I have a friend of a friend who did a stroker 2.3, built internals, turbo and he was only ever in the 12/11s, so thats probably why you dont see much turbo 2.3l posts.

I messed with one a couple years back , not knowing all I know now I never worked all the bugs out. Had a built head and a 50 trim. I plan on going back to a 2.3t when my current beater/dd let's go.

Subscribing.

There are two guys in Ohio that have raced year after year in true street with 4 cyl turbo cars. Clean, well built cars that run in the 9's and 10's. Not sure if they are around here on the corral.

Yes, your friend's failures are CLEARLY why this section of Corral does not have alot of 2.3 turbo info.

I understand that most guys on this site are into V8's, so am I. I'd just like to change that a bit. I've been on the turbostangs forum, not a lot of activity there last time I was on(a while ago). I'm proceeding forward with my project.
Next step is to get it back on the dyno and tune it all motor, just to get my feet wet with the parameters and get to know a little of what the engine likes. I will not keep anything to myself and everything I do will be public with it, both success and failures. Only running 11's with my 2.3 dd is something I'll suffer through, lol, what was the point of that comment anyway?
After I get the all motor gas tune done, and document the mpg improvements(I hope), then it's the swap over to E85 to see how it likes that and what the mpg drops to. Then onto the larger injectors, maf change and turbo install. This will be a fun dd that also has a decent enough suspension to race it at the track on slicks. I think it will be blast, so if you have any interest at all, check back often... If anyone else has a project, post it up in here. We'll get this moving somehow.

I just looked back at your original post. Are you going to ditch the flowmasters for a more turbo friendly muffler selection? So you have a factory NA motor that you plan to toss a turbo on to then learn with? Or is it a factory turbo motor that you are running NA at first to learn tuning techniques with?

I have a 86 coupe that's been converted with a 88TC motor. Only upgrade so far to the driveline is , 3.27 gears, centerforce dual friction clutch, and Stinger 3"DP to 3" in/out hooker aero chamber. About to thow a bigger fuel pump and manual boost controller so I can turn the boost back up. No BCS limits me to 8lb at the moment.

Other mods include:
Hallman boost controller
MM solid rack bushings
MM steering shaft
MM bump steer kit
MM cc plates
Koni shocks
FRPP C springs
Steeda x2 balljoints
95 spindles
95 GT 8.8 converted to fox length
Yukon 5 lug axles
North racecar rear brackets
03 cobra front brakes
95 Lincoln towncar 1" bore master cylinder
Wilwood perportioning valve
MGW shifter
Aftermarket 2 core 100% aluminum rad
18 x 9/10 94-04 offset wheels
234/45 & 295/35 KDW II

Yes, planning to ditch them after the turbo install and power starts approaching a level where the mufflers become an issue. I want a dynomax cat back on it. I just put these on so I could get the front pipe made to mate up to a V8 style catback.

It is a factory n/a engine that I am putting a turbo on to learn with and to start piling power too. I have a few back up engines that I am going to select one to put forged pistons and good H beam rods in the shortblock, then a good port on the head and a good camshaft, port the intake, etc. All in due time. I figure these stock 2.3's are stronger than a 4.6 with powdered metal rods and cast pistons, so I should be fine up to 250 hp or so.

Sweet Ride! Love the 4 eyes. Sounds like a killer, fun dd to me! Mine has rear turbocoupe 8.8 with stock disk setup currently, 96V6 master cylinder, MM 3-2 conversion tubing for master cylinder, front are V8 spindles and performance friction pads with rebuilt Lincoln 73mm calipers up front. V8 front and rear sway bars, Spec stage 3 clutch, billet shifter. It's fun, a little loud, and I drive it every day. It's a blast to take through corners, but def lacks in the power category.
My goal is an 11 sec dd that handles well and is just fun to drive. I have V8 race cars, I wanted something different.
My car is factory a/c delete which I thought was pretty cool when I bought it, but now that I have driven it in some 90+ degree days, I'm starting to rethink that, lol. I believe a/c is in my future for sure.

Keep em coming guys!

You using the factory twin plug head still?

As far as the flowmasters they are going to hurt power production as soon as a turbo is on there. Not to say you can't make power with them but being chambered mufflers it will cause you to not make the potential that your combination will have.

Agreed, just have to tolerate them till budget allows a change is all. Yes, still using the factory twin plug head, so twice the expense to swap to a colder plug, lol. I'm also tuning with SCT, then on to moates, using the maf computer. It will be interesting and a challenge that I'm up for.

Is the computer in the 4 bangers the same actual computer a 5.0 uses?
Good question, it's physically the same yes, same internals, less 4 injector drivers of course. It's got all the same parameters and tables that a V8 one does. I'm going to get the catch code and open the tunefile tomorrow or sometime this weekend at the latest. I'll know a lot more at that point. Not a lot of info out there on doing it this way.
Talked to ProM and they can do a calibration that will work for the 4 cyl computer, so that was my only speedbump in doing this so far.

so your taking a stock n/a 2.3 and converting it into a turbo motor??? how much boost can a stock one take?? would be fun
Now you're thinking like me! lol, gonna find out. Here's my line of thought, guys are turbo'ing 4.6's with powdered metal rods, hyper pistons, and cast cranks. A 2.3 non turbo engine has a stout cast crank, forged rods, and hyper pistons. Way I look at it, this should handle upwards of 250 hp or more before something lets go. I'm going to push it's limits till something does decide to hit the exit.
Well, over the weekend, was on my way into the shop in my trusty dd 2.3 coupe and the timing belt decided to let go. I knew right away what had happened, so coasted into a parking lot and called AAA. 2 hours later had a new belt on and the car seems to run better, maybe old belt was stretched? maybe I'm just crazy? only time will tell.
Stupid stuff like moving and finding a new place are taking all of my time and cash currently, but as soon as we cement our plans and I pay for Disney(6 year old doesn't understand why dad's turbo is more important than Mickey), I'll be ordering my kit up.
