How can I tell what engine I have?

From what I read here, you can't bore a Pinto 2.0 out to 2.3, but a Ranger 2.0 block is just an under-bored 2.3.

My other block is a Ranger 2.0.

I'll have to go re-read the sticky! :icon_thumby:

Edit: All I saw in the sticky is where it said 2.0 is an under-bored 2.3.
I think it was Mark that said a Pinto 2.0 can't be bored to 2.3L because the side walls would be too thin. (= different block).
I think I mentioned the block differences a while ago but I didn't realize the difference of pre 89 2.3 engines...dang...means I can't stroke my 87 block...ah, well, I was kinda hoping to score a later model like the 96 with an M5OD-R1 transmission...


you can't throw a 2.5 crank in a 2.0 block or any pre '89 2.3 block for that matter, the 2.5's are small journal.
Good point...I don't remember ever seeing anyone mention this previously...thanks...now the search can be narrowed down for my application...:)

Good information to know before I go out on wild goose chase for nothing! (I have been known to do that!)

It's ok, a strong 2.3L will still be way more than I have now. Hell, a weak 2.3 would way more than what I have now ;)

So just to clarify, a 2.0 Ranger block is a different casting from a 2.3 Ranger block, and can not be bored to 2.3 spec, right? I apologize if I am misinformed on this topic and have passed on incorrect information.

This is from the sticky-

Blocks-
2.0 is an underbored 2.3, with the exception of the bore the blocks are identical to all
2.3’s


The only question I would have at this point is is the Mustang block the same as the Ranger block.

If it is, then I can use the 2.0 I have (Ranger) and build it right. Even if I can't bore the Ranger block out to 2.3, I could still bore it out some and balance it. To me, there's nothing like a balanced engine!

The mustang 2.3 and ranger 2.3 are the same engine...the ranger went to an 8 plug head a few years before the mustang...

I wouldn't advise boring the 2.0 but you can have it honed when replacing rings and pistons...there may even be a forged piston for the 2.0 but not sure...but you don't need those unless you plan to some day used forced induction...and even then only if going over 5 psi...or so...

If you are planning on any short block work I would suggest find a 2.3 and over bore it...add new pistons and rings...maybe shave the head a bit...then drop a 4 plug head on it that has been reworked...maybe even put a slightly longer duration cam...but that's about it...

I guess if you want to use what you have then there is a bit of limitation...

When I obtained a 2.3 short block to replace my 2.0 I had them side by side...I was poking around checking the differences when I happened to put my hand on the 2.0 piston...I was able to actually move the piston side to side when it was at TDC...every one of them had quite a bit of wobble...I did the same to the 2.3 and the pistons did not budge at all...

This told me the 2.0 was severely worn...and I was quite happy to put the 2.3 in its place...

Thanks Mark, I'll freshen up the 2.3 and be happy!
A bit of good news on my parts buying. I told you the guy "changed" his mind and wanted to keep the turbo. When I went back to get the engine, I said he ought to give me something in place of the turbo. He said what do you want?
I'll take that pressure plate -says I.
I just looked it up- low price, $300 -high price, $1000. It's for a 911 Porsche. I don't know what he had it for (and neither did he).
So, I'll let it pay for all the stuff I got!!!

Mark, when you can wiggle the pistons in the bores by hand, your motor is definitely in a bad way. My 2.0 was .060 over when I got it, which tells me it was likely rebuilt more than once, probably 3 times, in the 200k that I believe are on it. I do not believe any forged pistons are available off the shelf for the 2.0. I looked at one time. You can get pistons made at fairly reasonable prices should you decide you want to.
Itlives, great deal on the pressure plate. Good luck selling it. Sounds like it could pay for the whole engine you purchased plus the extra block you need.

yeah, they were well past their "best before date"...:)

Not sure about the forged pistons either but anything is possible these days...with enough money and time we can build anything...

Mark- I don't know if you're movie buff, but you should watch "The Worlds Fastest Indian" if you haven't seen it. Anthony Hopkins stars as the guy that set the world land speed record on an Indian (motorcycle). Great movie!
It starts out with him making his own pistons.
True story

Why do advise against boring out the 2L if it's the same block?

Ok, I got the head off my engine. Just in case there's a visible difference in the n/a pistons and turbo pistons, here's a picture of the top off mine. Can anyone tell if they are n/a ?


Wrong pic -duh

yep, they're dished...at least they look dished...the 2.0 and 2.3 are both flat head pistons...maybe a slight indent on them where the valves would meet but otherwise flat...

if i may jump in ..

they are definatley turbo pistons. Hopefully they are original Ford forged, and if so if they are not damaged..someone may pay you something for them. 8.0 compression will not run great unless turbo'ed. I would mic' the holes to see what bore they are...if the rings aren't scored..it's has value as is..

mornin' Mark..

Ok, I guess I need to take the block apart this weekend and check sizes on everything. Does anyone have a recommended brand of kit to buy.

Guess I'll have some turbo parts to sell soon. I don't want this to drag out!

at the risk of offering TOO much info..

too bad you aren't near someone with a NA running engine for sale or trade etc....instead of taking that apart and interrupting the seating rings..etc...the bore is most likely standard...you could take a bearing cap off and tell what bearing you have.,

All Turbo blocks are large journal crank, (if the block has has a turbo oil drain hole)...

if someone would want the pistons it would be best to leave them connected to rods etc...those pistons are hard to find and are no longer available from FORD...There are aftermarket non-forged dished pistons out there so finding out what you have would be good...clean a top of the piston w wd40 and see if it has any markings...

Anyway...those heads (actual turbo'ed) are rare uncracked, so if it's all been done..it's kewl...and it would be great used on flat top pistons..

i wouldn't buy a kit for that motor,,I would piece together what you need...
but first decide what you're going to do for pistons and rods..

to run a carb..or even EFI, you will want flat tops though..
that may be a good engine to use as a turbo'ed install for someone..
