Yes, the 2.3 may porduce the same amount of peak horsepower, but at lower rpms, a stock v8 will eat a 2.3 anyday of the week. Its the torque too. the lacking of the other 4 cylinders is very harsh to power numbers.Even if it is turbo, whooptydoo.... it doesn't compleetly spool up until what? 4500 rpms? By the time you get it revved that hight the cars there were beside you will be in the next county! lol. I know that you aren't building this for speed, but I think that you will be highly dissapointed in the mileage you will see out of this thing. The engine will have to work a lot harder to accomplish the same task as compared to any V8, so the 2.3's fuel mileage will drop because it will require more fuel and RPMs to create the power that you need to accelerate, climb hills, ect. I too think that it is awesome that you are doing this with your daughter, but I hate to see anybody spend time and money to only be dissapointed in the long run.

I've contemplated building a 65-66 coupe with a turbo 2.3, 5spd. It would be light and it would handle great. I say go for it. A properly sized turbo will spool at whatever rpm you want it to. Huge turbos capable of monster HP are the ones that spool late because of large turbine housings. A small turbine like a .48 A/R should spool in the mid to high 2000 rpm range. You won't need anything more than a T3 to make that car scoot. Turbo cars get pretty good gas mileage too when you're out of the boost. You can even tune the svo computer (or modify a A9L mustang EEC) to run the 2.3l with a TwEECer. It's nice to see someone with some imagination. Good luck with the project.

I agree with fastback69. Do what you want. As for that little 2.3T SVO motor, don't let anyone tell you there junk. There are a couple of guys around here that run them at the track and pull high 11's all day longin the 1/4 mile. They drive it there, beat the hell out of them and drive home, hour and a half both ways..I think your going to have fun with a small displacement motor, not so much grunting out at the low rpms but a weapon none the less..

Good luck..

Default RE: 2.3L Turbo swap into 1967 Mustang

what are you guys talking about? a 2.3 turbo in stock form will easily eat up a 2bbl 289 in the 1/4 mile, with a few mods the 2.3 can pump out 250-300 hp easily and still be fuel efficient in fact theres some 9 second fox mustangs that do wheelstands running 2.3 turbos.

The 2.3 turbo will become a popular swap as fuel prices soar. I have looked for it but years ago there was a guy who did it in a 65 falcon along with a 5 speed, it used a BIG junkyard intercooler and a cam change, head porting and more boost, it ran in the high 12's low 13's and did around 30 mpgs hwy.

The other benefit is less weight on the front end = better handling. I had an 88 turbo coupe and I know it weighed alot more than my 67 and it ran pretty strong and I consistantly got 25+ mpg's at 80 mph.

Then again, a bone stock 5.0 ho efi and 5 speed can pull 25+ mpg's hwy and add a turbo it even goes up but city driving is maybe 15-16, with my foot 12-13.

If your good at welding and fab I think it would be an easy swap, I would start with the latest model efi 2.3 donor you can find, preferably the 200 hp version, you have to realize the 200 hp 289 did make more low end torque but in todays sae ratings only made about 160 hp compared to the 2.3' s 200 hp.

heh, the 2.3's are nice but i don't know about eating up a stock 289 but weirder things have happened. last 2 svo's i saw running were 16-17 second cars in stock form. i think my 289 @ stock was a wee faster then that.

No "close to stock" 2.3 is going to be fast. I have worked on several in foxbodies and thunderchickens (T-Birds) that had these engines, and all of them have been really slow. You can floor them and they just putt along like you have all day to get there. Of course, they were all bonestock, and had most had close to 100k on the odometer, but overall, they left a bad taste in my mouth. Maybe a fresher engine with a few good improvements would be better, but there is no way a stock 2.3 turbo will out do a 289 or 302.

Found this video of a 2.3L turbo Mustang taking a 5.0L Mustang in the 1/8th mile. Looks plenty fast enough to me. I say if it's what you want to do then go ahead. There will always be purists that think its wrong but so what.

I must be a purist. I bet that 2.3 wasn't anywhere close to stock either.

A 2.3 turbo car dominates true street in drag racing. I've seen him as far as .40 seconds ahead of the closest competitor. It's lighter and a more nimble car with it in there. If everything is the same, weight, power, body shape, a small motor will always pull away. It more difiuclut to make power in a smaller motor, but he never said anything about wanting to go fast in it. I would personally put a 2.3 against a stock 289 any day. A stock 289 can't get out of it's own way.[sm=gears.gif]

I knew this would be interesting alot of peole would not agree, but in the end it is your car and your money. If your daughter learns how to do something this interesting, she will be way ahead of me! Are those motors easy to find parts for? I still drive by aplace that has a SVo stang sitting for sale I should stop as they are probably getting rare?

im gonna throw a +1 for a later model 6 cyl swap.

if you decide to build the 2300 then i say more power to ya, but stay away from the 4.0 V6. those things will end up with cracked heads if you even look at them the wrong way. seriously, dont ever overheat your exploder LOL.

I know my way around the Explorers....I have 3 of them.

In my family we have had 8 or 9 of them....Quite frankly the single most easymodern car to work on. I have modified them....and made some custom never before done stuff to the motor as well. As for cracking the heads, Yes, that was common in the early years...but the easy fix is to swap on 95tm heads, which bumps the compression AND the exhaust seats are something like 3x thicker than the 90tm heads...

The transmissions areTHE weak point on the Explorers...I have PERSONALLY re-built the M5OD-R1 in my White Explorer 2 times. The first time I just dropped instock replacement parts. Then I cracked the case on a hard launch...then I replaced thecase, and upgradedsome of the internals with the updated components that Ford added in later revisions....

Youguys have totally lost the point on this build.....If I wanted to give my daughter a FASTvehicle, I would havesaved my12 sec. Olds Cutlass, and given that to her. That was the first car that she helped me build.

12 sec. and 20 mpg is EASILY achievedin the 87/88 Thunderbird Turbocoupe.....I'll be subtracting350-500 lbs for the swap into a Early Mustang over the TC.....She will be happy with 13 sec. and 30mpg which is even EASIER to do....

How many guys herewould be TOTALLY OKAY with their teenagerdriving their'built' Mustang? Not many. And I'm not okay withmy daughter having350+hp at age 15.......

what about a s/c 3.8 from a later tbird? popped head gaskets suck but other than that they are great motors.

oh yeah, i've seen 4.0 heads with cracks that literally went all the way around the head - not just seats (worked in a machine shop for years)

Default RE: 2.3L Turbo swap into 1967 Mustang

I'd go for it. The concept is great. the 2.3 is a good motor with lots of potential. They have been around since the 70's in Pintos. I had two Rangers with the 2.3 non turbo and I pulled a trailer with full size cars on it. The idea is right for the times and it would be cool to pop the hood and see a nice conversion that looked factory or tricked out. I have a big block inmy 67 and while it's mildly modified it will suck the gas. I don't know wher you live but I'd make it E85 capable too. Heck, I may swap a SHO V6 into mine if gas keeps going up. I had an 89 SHO 3.0 5spd that would fly and get decent milage too. Good luck and plus 1 on the other saftey stuff too.

I think the idea of a 2.3L svo is awesome... do what you want with it and by the looks of it you look more informed on the issue then most of us anyways. I know saying this is gonna make alot of guys mad but stock 302s and 289s are just nothing special and alot of 4 bangers (Not saying the 2.3, im just not informed iin the engine)these days are able to destroy them even in stock trim... alot of 4 bangers are alot more advanced then these old motors and out perform them... That being said i love the old 302 in my 72 sprint and its def. the way to go for me... but again, how many 2.3L 60s car are out there? It should be awesome and good luck, could be a dud but if i had the skills and patience i would go for it.

As for safety upgrades, we are going to install Explorer Rear disc brakes. It's a bolt-on for the 9" rear that's under there now.

We will also be adding 13" Cobra discs up front....of course they will be power assisted. As will the steering. Probably going to install a R&P.

3 pt. Seat belts will also be installed.

Minor suspension upgrades here and there. Nothing radical.

i had a 84 svo i bought it for 1k$ it wouldnt boost to its stock 14lbs w.o falling on it face(the spring in between the air cleaner and the turbo was gone) i fixed that upped the boost from 14 to 20 psi and it stock 5.0 and 4.6 99-04 gts for breakfast and still managed 35mpg on the road as long as you stayed below 78mph


i miss it dearly[:@] the turbo locked the next day up after a 140+ mph dash in the middle of no where. some guy cam eand bought it and drove ti to atlanta i will buy another asap from either going back to work or from my settlement it wil be my DD and i think im gonna mod it slightly suspension and a holset turbo(perfectly sized OP you can find them on dodge diesel trucks)
