Yea and that should work

I'm so excited, I feel like a child in the beginning of December.
🎶 Turbo time Is almost here, time for boost and time for gears,...
ok bov, piping, boost controller, has to be ordered when the turbo arrives. I dont know what size waste gate it needs.

Can you sell me a tune for the sctx4? is it going to be necessary to tune it with 6 psi boost?

57mm wastegate is the max i would go, but also the wastegate is controlled by a spring, be easy in first gear do not launch it in first unless your ranger is running 4.10 or smaller such as 205 70 15s or youll blow the 7.5 up I've done it with 4.10s and 235 75 15s, the duratec with 6 psi and my tune makes about 218hp and 240 tq more than the 4.0 sohc

I'm running 235 80 15 on a 410 7.5 now. I've been searching for an 8.8 with disc brakes all morning. Probably going to have to hit the junkyard. The 7.5 won't handle large tires anyways

So how would buying a tune through you go? Do I send you my tuner or do you email it to me?

I will send you the tune files and you can either email me, direct message here, or use my work phone to contact me, and go from there

So i have a big update, with the 6 speed miata 2,0 trans and the explorer 8.8 4.10 and 235 75 15s i see about 38 mpg at 80mph and about 45 at 55 mph when air temp is sub 90 degrees at 1800 ft elevation, i bet with the 10R80 and this setup we could break 50mpg! i commute 216 miles every monday and friday and thats my avg (+ 2mpg max and - up to 10mpg because of how much of a hurry im in when accelerating)

what i can do as of right now is leave you my email (would be in private messages) and you would hold on to your tuner and i will email the flash tunes unless you dont have a way to flash the tune onto the flasher then i could assist you there, about the cost, would have to ask in private messages as i am not a vendor (hopefully will be able to soon as i can also work on the older Lima series and the V6 engines aswell)

I haven't ordered the tuner yet. I'm waiting for the turbo to arrive, and figure out everything on where to place it.
With the president's new mandate, I might lose my job. Sometime between next week and 3 weeks from now,, it will arrive. I'll check my messages as soon as I fire out how.

Your MPG is super impressive with that 2.7 you're running. I also drive 200+ miles everyday for work. I wish I wasn't spending $50 a day on fuel. Are you sure that you're not running lean?

I also blew the 7.5 rear end on 235/70/15. I still don't know how I did it. It had a 3.73 ratio, so I switched to the 4.10.

Still searching for a great deal on a ranger 8.8 with discs

For the fuel ratio I run an AEM AFR gauge to check fuel and I run 89

sweet looks like the turbo i run! based on that size your boost will start to peak 1 lb by 3600 and build from there so itll be exceptionally streetable

I'm sorry. It's over. I got a head on collision today. If anyone wants the turbo. Message me for details. I'll re sell it for the price I bought it.

It's a comp turbo. Water cooled. I can send more details later..

I'll be ok. It's just a truck. I'm in pretty good shape after it. I went looking at the new Rangers yesterday. I don't like 'em one bit. I felt I was in a lifted version of my girlfriend's focus.

I'll get another truck soon. I've been looking at the 2014 single cab Toyota tacomas. Stick shift, 4x4, traction control. That accident wouldn't have happened in my f150 because it has traction control. That old ra ger didn't and I doubt they had a model that did. I could be wrong about that though.

I sold the truck to the junkyard yesterday for $750. Bummer.

Hey, I have a 2009 2.3 that feels so dog slow even compared to the 1st gen Scion tC I used to have. Between them, the Ranger is about 100 pounds heavier and only down 15HP and 10lb-ft theoretically. I've been having some engine issues such as the occasional hard/long start, idle dips after small throttle tickle, and a hesitation or zero power moment off idle once I get it rolling or if I take off super gently in order to be nice to my clutch like a good boy. A quick clutch kick will get it going, or taking off harder with higher revs, too.

Anyway, I was wondering what could cause these symptoms and what I need to do to make the engine first run properly in its "factory" form. Other than that, it doesn't like going from 2nd to 1st when downshifting, and I usually put it into 1st at a stop before takeoff by sliding into 2nd beforehand to "align" the gears rather than fight and force the stick into 1st. Does something similar for reverse, but not as bad, usually a double tug will get it in no problem, but again, comparing to my tC it didn't have either issue.

After I get those functional issues solved, I want to know what's the most I can do to the engine for more power and response without spending money on parts or tunes (I have tools) and how much will I gain from that? After that, what's the most bang for buck way to get more power everywhere, a wider powerband, and not lose anything like power steering or AC, and how much will I gain from that, and how much will THAT all cost?

Lastly, what're the general power limits of factory stuff like injectors, fuel pump, transmission, radiator, etc. I know the 7.5 needs to be replaced with an 8.8 and plan to do so in the future by scrounging together a junkyard Explorer axle pull and I'll simultaneously get an LSD and 4.10s even if I have to take apart two axles at the junkyard to do it, but I want to know if the stock M5od-R1 is good to ~330HP and torque like the spec sheet claims or not. And, regardless of whether it is or not, is the 6-speed Miata trans you spoke of up to the task?

Also, what are the ratios on the Miata trans, BTW? I have trouble believing anything over 30MPG Hwy in something truck-shaped, especially if you're turning more than 2500 RPM at ~75 like I think you're doing with 4.10s and short tires. (again, I dunno the Miata trans ratios, it's 5th might be .63 or .50 for all I know while our M5od-R1 is .82 garbage or whatever)

What's the advantage of the Miata transmission? Are the gear ratios that much different from the ranger 5spd?


It's been like a year since I've been on this thread and a lot has happened

hey snarfy, sucks that you lost your truck. I have one exactly like it and I love it! There is rangers with traction control but only on the fx4 options 06-12 and newer I believe. However, I might be interested in taking that turbo off your hands if you still have it. I may be looking into doing something similar in what you have planned as I also live in California as well or do a whole exhaust manifold swap and changing back when needed for smog. Let me know thanks!
