I believe the 58's are easy to spot out
if I'm remembering correctly , the 58 has only one vacuum fitting on it's top
46 & 52 have two vacuum fittings

On the 2.5L TIII I built (still on the stand, ugh...) I used a stock-like Holley 58mm throttle body I got from Adam Lengel that was CNC machined for true 58mm bore throughout. I am using a stock TIII intake manifold, and the transition into the intake is about perfect with just a little opening up to match with a flap sander.
That is interesting because I wonder if there is flow loss from going to a little diameter (T/B) to a bigger one (plenum) directly or it would be better to make a transition (cone).

Haha, I know that.
BTW what ECU, distributor do you use ?
I would like to use the stock 89 electronic but the intake doesn't clear the distributor and furthermore the I-shaft sprocket is too small
This 2.5L TIII I built will be for my '91 Spirit R/T. I am dead set on using the existing '91 TIII SBEC electronics. When I was building this, I had hoped to get a proper cal from ShelGame. I really don't know what my options are at this point since he is no longer doing that. I admit, I have practically zero knowledge on how to do my own..
I still plan to at least get the new engine running and broken in with the stock '91 TIII SBEC/electronics. I think it will be OK as long as I keep the boost low (10 psi or less, 91 octane or better). The car does have a new full 3" exhaust, ported exhaust manifold, slightly ported intake manifold, modded 58mm TB, and a stock TIII turbo (for now). Also a stock intercooler. My plan was to get it broken in and driving reliably before doing anything else....the head and cams are stock as well, and it is using a slightly thicker Cometic head gasket and ARP head studs.
This 2.5L TIII SBEC is something I will eventually have to throw money at....which I'm totally OK with, but I am dead set on retaining the cam/crank sensors and stock electronics.
I have a Jeep 4.0 60mm throttle body on my car. Had to ghetto rig up a cable bracket and Dremel the 2 holes out to fit. I also ditched the IAC for a manual IAC but you should be able to use the IAC.

Thedon809 is this T/B the same :

The holes you are talking about is the two ones used for fixing the T/B to the intake (the Jeep has 4 holes)
Do you think the sensors are the same ?

Iturbo, I Don't have the TIII harness nor the TIII flywheel and trans so I only have to use the SMEC or go aftermarket ECU
Yeah, that's the same thing. Yes, if you look closely at my picture, you can see the hole I wallowed out. You can use IAC with it. You'd need the IAC with the larger pintle than our stock throttle bodies.
I think I have a caravan 58 I'm not using...
I'd love to see the looks on the faces of those Eurotrashers after you smoke them with a Shadow!
I was wrong. I found my old throttle body and put the part number 4861333 into the google webs and it came up as a 1999.
me too:)
But I think it will be very difficult to beat these cars with so much torque, power and 8 speeds trans (or even more) …
Look what the challenger become after they upgraded the trans

It you sell it PM me please
I hope, so much years to learn and money spent to get the required parts and it is not finished
I always wanted to build a 2.5L TIII after hearing that a one-off Dodge Daytona IROC R/T was made with one for Bob Lutz (Chrysler CEO at the time). It was called the "Ultimate Daytona" I believe. I could have sworn there was a blurb about this on allpar.com, but I cannot find it.
Anyway, I was a huge fan of the 2.5L turbo after getting my '89 Dodge Shadow ES long ago, and it always seemed to me that the low end torque (2.5L) along with the high revving capability (TIII DOHC) head was the best of both worlds. Can't wait to find out!
