i was wondering what the bore and stroke are for a 2.3l and a 2.5l

 

the 2.3l Bore is 3.520 in (89.4 mm) and stroke is 3.126 in (79.4 mm) for a total of 1994 cc displacement

the 2.5l is stroked (by 7 mm) making it a 2.5l

does this mean i can just drop on a 2.5 head to my 2.3???

 

i jus asked that about 2 posts down...no replies but from what i read the heads will bolt on fine...jus dont know how anything else will work

 

is seen your post and was hoping that if more people showed interest in this question maybe some one will give us a good answer???

not that i havent done some of my own research but i still have a few questions?

 

i will get the link i found it on...i will let you read and interept it your way and see if we can come to a conclusion...its on the heads section...but it has alot about the pistons, heads, cranks, rods and alot of other things...

thanks man ill read it when i get a chance and tell ya what i think

 

im still doing homework....trying to find some more info

 

"All 2.0/2.3/2.5 heads will physically bolt in place of each other, they all have similar
exhaust port shape and placement. All cams are interchangeable as long as they
are used with the proper followers. Later model ('95 and newer) roller cam
followers cannot be easily swapped onto an older head as the valve stem size was
reduced in the newer heads and matching slot in the follower was reduced.
Early 2.0 and 2.3 heads have the same small round intake ports spaced evenly apart, they
differ from each other in their valve sizes though
.
There are several variations on the 2.3 heads though they break down into 4 distinct types:

1. Passenger car oval port heads-’74-’80 Mustang, Pinto, Fairmont, Bobcat, etc.
2. Passenger car D-port head-’81-’95? T-bird, Mustang, Etc.
3. Truck round port- ’83-’85 Ranger
4. Truck D-port- ’89-’01 Ranger. The '89-'94's and '95-'01's have different combustion chambers and ports. IMHO, the newer head is better designed"


so basicly what i got from that is all 2.0, 2.3, and 2.5l heads are interchangeable and this should bolt on without any problems???

anyone want to prove me wrong????

 

the heads will bolt on...but timing belt is all i was worried about...

 

ya i know the head is a direct bolt on but im not sure about the timing belt. it should be fine. would any sensors need to be changed??

 

i would not think do...wish someone else would join this lol...been lookin at cams too but gotta get alil better head first..and finding info on these head changes is difficult

 

yur right info is tight on this... someone else must have had the idea of this frank motor and done this swap i wish they would come forward and share there knowledge with us???


what year is your ranger?

 

97...2.3 lima...and well only thing that holds it back is head flow...

 

mines a 94 and your right the flow sucks and the trucks got weak power im hopping to improve this with only a few mods it might even turn into a 2.3/2.5t in the near future

 

i too have a 2.3 lima and am very interested as well. What would need to be replaced? removed? modified? adjusted? and what are we FULLY includingin this swap?

 

i think this might be the answer to our questions

"If the 2.3 has a dual plug head,then yes, it will fit the block.You'll need the 2.5 intake and throttle body for that head.Is it worth it,I'm not sure.It is good for a turbo."

 

would the cc chambers be smaller then the 2.3 head? if thats so it would lower compression and be better for turbo and not N/A..i have a 9.4.1 compression ratio and thats high but its a 4 banger and they are always higher. As for intake and that does that mean the 2.3 sensors will work...i would think so, dont think anything was swapped between the 2 rather then main compents...

And good info...what forum did that come from lol..

 

no im not sure if the cc would be smaller or im not sure if the sensors would work lol i imagine there all the same and i found this great little turbo ranger forum http://rangersrevenge.com/ check it out

still searching

 

read my old thread ab out heads on here...guy soes into good detail...basicly its not worth it they both flow like crap

 

do you need a 2.3 head?

i have the head off my 97 that threw a rod, the motor only had 149k on it.


i am putting a 2.5 in my 97 soon, im just trying to get the money for it.
as far as i am told, the 2.5 is a direct swap, you just use the accessory's from the 2.3

 

LOL dont wanna pay shipping for a head

 

it wouldn't be that bad, i want to say around $20 with ups.

 

instead of saying its not worth it. try posting prices you think are involved and let us be the judges of that. as well as any comparison between 2.3 and 2.5 so we can judge the value ourselves please.

 

both heads flow the same...port and plolish will be more cost effective and probably less work

 

already plan on doing a P&P. but nothing else will be too terribly effective will it?
