Isn't that the point of saying "use the search function". Who cares if it was started 10 years ago, valid information is still valid.

I've also been lookin' for a stroker kit for the 2.5 in my 1988 S-10.
Not wanting to make a race motor, just want more torque out of the lumberin' pig.
Anyone have some leads on this yet?
I think Eagle Rods could score big on this concept.

Iron Duke Stroker
Every body interest in this is coming up short as far as I know. Jeep used the 151 last. The 173 helped so I am told. After market Blocks and/or heads seem to be a viable engine. But expensive. Evolution to the Quad 4 made a good engine,but with EFI ,16 valves, etc Its hard to transfer. I haven't posted much lately. A rebuilt Quad 4 is well over 3000., Good but far evolved from the original. They are supposed to be durable, but at least need the truck block, or the racing block. The block is 2500 bare. I have a lot of info on codes for different uses and recommendations for parts.. I would be interested in 16 valves if it used carbs. I'm on hold, I don't know about anybody else. Anybody want a 944 -85model engine good engine.We keep trying, I can't keep paying for gas like I am doing now. thx m

I "hotrodded" an Iron Duke
OK, I almost hate to admit this, but I had an 82 Firebird (not Fiero...Firebird) which came from the factory with teh Iron Duke 2.5 liter 4-banger...yes this was the base motor from 82-85 I believe....all 92hp worht of it. Well, I got this wild hair thinking "If Porsche can get 150hp from their 2.5 liter, why can't I?" - it turns out the answer is "Because you aren't a German engineer with the funds to desing it from scratch" was the answer. In the end I:
rebuilt the 4-banger, .030 over
used 4 custom made Venolia pistons on stock shotpeened rods
a mild Crane cam
replaced the stock TBI unit with a larger unit (30% larger) from Holley
replaced the intake with Edelbrocks Performer TBI for 151 cu in motors (no longer made)
replaced exhaust maniold with Hooker Super Competition header (huge 1 3/4 primaries which really helped the bottom end torque - NOT)
replaced the exhaust with a free-flowing 3 " walker setup
installed a 75hp NOS Nitrous setup (single fogger nozzle)
I actually got to "race" (I use the term loosely) an 84 Firebird with a stock 4-banger and it wasn't even close (off the bottle), so I know my mods made a differnece, but so what - it cost me a ton, and was still slower (off the bottle) than a stock 305 for that year. On the bottle at the track I think (it has been 20 years) I ran in the 9's (1/8 mile folks, 1/8 mile).
For what it's worth...

Kansas Racing Products, http://www.kansasracingproducts.com
An inline four cylinder block based on the Pontiac Superduty-4 engine. It will accept all of the Pontiac SD-4 components. Also, the block can be ordered to be finish-machined to accept virtually any smallblock V-8 cylinder head...GM, Ford or Mopar. Displacements from 140 cid to 213 cid...up to a four inch stroke crankshaft and 4.125 inch cylinder bore. Roller camshafts are supported by five journal roller bearings. Bellhousing parttern can be ordered to accept most common bellhousings.
A KRP engine has never suffered a block-related failure even under high boost conditions!!

IRON DUKE CROSSFLOW MY book says no, would not take it for gospel though. Probably not by all counts , I am beginning to get enough material together to have realistic answers, but I am not well organized yet, but I went through a bit of listings,books,etc. mark
|04-04-2006 06:05 PM|
Hey guys.Was the original Pontiac Fiero cylinder head a cross-flow design?
Was it done in aluminum?
|04-04-2006 12:36 PM|
yep, thats about all I know on the subject. The old habits die hard, but Pontiacs history has never been toward the high end. Everybody jumped on the over cam-Pontiac did it thru Aussies, Brown and something,I think. Pontiac slant 4, Early 60's tempest half 389 all the way. International half of 345 v8,I have a couple v8s nothing to do with them but run in farm trucks and such.mark ps There used to be some good scout used parts and groups. I did not totally quit, butI am going to try to get out this year. I have 2 4x4's out there besides scouts I am looking for a engine-IRON DUKE ?
