I'm looking for some specs on the 2.5...if I remember correctly...didn't Ford produce a DOHC model? I found one site that gave HP but that was about it...I'm looking for torque/engine weight/compression ratio/valve sizing/etc. The only 2.5 experience I had was with a relatively new (at the time) parts delivery truck when I worked at Autozone...one of the guys commented about how it was ballsy for what it was...I laughed at him...and the next time I drove it, I stood on the throttle and was pretty impressed. I'm assuming it had the 5R55S tranny or something similar.

My plan is to pick up a base model 4-banger fox-body 'Stang and transplant the 2.5 and auto tranny with it...that along with 4.30 gears and a total weight of hopefully no more than 2700lbs...well...it should cook(especially with the Eaton M112 I will be using).

So any and all info you guys could help me out with will be greatly appreciated!

Thanks,
Don

They made a prototype, but never sold one. Since you'll never lay your hands on it, does it really matter? If you gotta have a DOHC, easiest way is to buy a duratec Ranger, or you can always build one using the Volvo DOHC head adapted to a lima engine, but it's A LOT of fabrication and offers little performance gains for the time and money invested.

My advice, skip the plans on using a supercharger - a turbo will be easier & cheaper to do, and make more HP without stealing power to make it. A good turbo setup will blow away a blower just about any day.

Well, now I know it definitely wasn't a DOHC 2.5 I drove...lol. The S/C set-up will be significantly cheaper and easier than a turbo swap...plus I refuse to run a 2.3...too touchy, I've never had one good experience with one. An eaton 112 pumping 18lbs of boost will blow away the turbo set-up and be lighter. The late model M112 uses a vacuum operated by-pass valve so when not under boost there is minimal parasitic loss...fabrication is not a problem for me, it's what I do for a living and I can pick up a used M112 for under $400 and get free materials from work. I understand the principle of using a turbo on a small displacement engine, but an M112 on a fortified 2.5 will cook...it'll make boost from basically right off idle all the way to redline.

A 2.5l lima is just a stroked 2.3l, so no real difference there, till they were replaced midway through '01 with the all aluminum DOHC duratec 2.3l - that's a whole different engine. There is no effective difference "touchy" or not on the older engines, so not really sure what you mean there - they are a rock solid hard-to-kill engine platform, and if you build them with the right internals they can make 300-500HP on enough boost.

I'd watch what you say about the turbos - there's some pretty heavy hitters in the turbo section that know their stuff, and have the machines to prove it. Many have built them on a shoe-string too! Sounds like you know your way around the blowers a bit, so welcome - always nice to have some experienced people with fresh ideas on the site!

No question that a turbo 2.3 can run...but you definitely have to put some work in to get them there...for those who don't want to or don't have the knowledge to blueprint and prep their engine for a reliable 230rwhp, a turbo 2.3 isn't really the way to go...replacing headgaskets would be a weekly process. Sure you can make a 500hp turbo 2.3...no doubting that, but how street friendly could they possibly be? I see rediculous turbo lag with a power curve similar to a light-switch. The only reason I like a positive displacement blower for what I'm planning is because it will provide a broader torque curve for better street manners. If all out power was my goal...then I would absolutely go turbo.

But right now, I need to source a cheap low-mileage 5.0 to replace the pile of shrapnel that now resides under the hood of my 'Bird.

So what you're saying is that the 00 2.5 is the same as a 2.3 and the parts carry over? (i.e. Headers)

Yes. Headers will be the same till you get to the duratec 2.3l in '01.

Hmmmmmm!!! Don't know where you get your info, but you need to find a different source...........joe b

I believe it makes 148LBft at 3000 RPM and 120 HP at 5000 RPM the 2.5 that is, if you still care about that. 2.3T is the way to go IMO

I'm looking for some specs on the 2.5...if I remember correctly...didn't Ford produce a DOHC model?...

Ford made a 2.5l DOHC 24v v6, I just found out today, my cousin has a 97 contour with one

That's the same displacement, but not the same 2.5l 4-banger that's in a Ranger. The lima was only sold as a SOHC design even though they made a prototype DOHC head.

I knew that, I just thought that he might have them mixed up, I do that sometimes
Its seems like a good engine though, the SVT model had 195 hp, it would be neat if that was in a Ranger
