i've been playing with my blazer, and trying to focus in on what engine i wanna swap into it. i know the obvious answer is ls7, and everything else is varying degrees of wrong, but while digging through the GM internet parts bin i stumbled across a hyundai 2.5 i6 that powers the chevrolet epica (holden epica, daewoo tosca, et al) . i'd rather not make my 2.5 fuel injection badge a liar, and from what dimensions i've found this thing is totally plausible. plus, according to wiki it was designed by porsche, so i might have to figure out how to stick it in the back (lol).

has anyone here ever had any expierience with these? i know it's probably a lame, soft, limp-wristed engine, but if i found one for the right price, i'd consider roadtripping for one (heard they were available in canada)...

if not, no worries. have a look-see:

it's gotta be lame, hard to find a pic without the engine cover...

other options include the duramax 2.5, ecotec 2.5 (but rather have something i can carby if gas)

or the lt1 from the nova.

or a mercury 181 from my uncles boat.

or whatever i find for stupid cheap that i can wring more than 100hp out of.

S10 Blazer I presume? An inline six is going to be much longer than a V6. I know that that is a small engine bay and shoehorning a V8 is difficult enough (but there are many aftermarket parts to help ease this). You could put a 4.3l from a newer s10/s10 blazer as well. Or an ecotec 4cyl, they used to sell the supercharged engine from the Cobalt SS, but I think they stopped it. Hell just get some rope, a yoke, and some oxen, anything is better than an iron duke.

If you want to keep it in the GM family, you could try one of the Atlas I-5 or 6 engines.

there's enough wiggle room to fit a 235 which would be pretty slick, and i saw a dude stuff a gm 250 into one. since i'm trying to keep the a/c an inliner is easiest, and there's a fair height notch in the firewall. since it's a pretty badass highway truck i've thought about a row-your-own TD/wide ratio drop it a couple of inches, bellypan it, and run rollpans and heavy tube bumpers.

a hot little banger would be fun, but i think i'd like more force at the crank down near idle to beat the wind. roadtripping to boerne i was running 55-60 (in a 75) and could easily draft rigs. up above 70 it's spinning hard enough to hold it's own, but if i ran up on a truck at 60-65 the wind coming off it wouldn't let me pass and a downshift would have dropped me to 45-50. riding the trucks i pulled 26.5. but it'll do better. running 60-65 (mild traffic) comng home i got 25, but my odometer gave out, so i'm SOL.

definately on the list. even if i have to split the radiator. the 4200 is the engine i've always wanted for the nova (with the biggest turbo capable). i've driven the 5 cyl in a colorado and was disappointed in everything. this blazer is going to have to sound good and i doubt a 3.5 will ever sound good. i haven't researched into it yet, but a 2.8 i4 atlas with ls7 heads and bits would probably toot my horn. even though i have the 'strong' E block, it's still weak, and the crank is weak, and the heads are super weak. i do like the TBI. single injector might be able to be played with right and make good.

i don't have to keep it strictly gm. if i can get a dirt-track 2.3 ford i'm gonna go for it.

It is a versatile platform that accepts anything. Be different with it. Try a cummins 4BT the 4 cylinder brother of the 6BT that made it's way into the Ram.

i wonder how cost prohibitive it would be to wind up with a 2bt twin. haha. big iron diesels are heavier than i'd care for. that wouldn't be the deal breaker, if i stumble across a detriot that would fit, weight and height be damned. isuzu has a few small (under 4l) diesels that look promising. but trying to look up bolt-patterns and gearbox options is kinda difficult.

There's always the venerable Jeep 4.0 I6. Power was good, torque was better, they last forever, and Chrysler made about 3 trillion of the things so it shouldn't be too hard to find one.

The S10 had an Isuzu diesel. Nice little mill but NA (easy to fix on a diesel given the added strength of diesel components).

i loved the 4.0 in my comanche. i put a HO topend, portmatched, and ran tighter rings with a gutted dummy cat, a moroso spira-flow dualed out through camaro tips. it sounded like a pissed off tug boat, but would haul the mail. in 4h i could walk the mustang kids, and could give the camaro kids a run for their money. would have kept it forever (buddy of mine totalled it, it got t-boned hard by a lady in a tahoe. i think the 'pepboys' racing seats saved his life. lol)

i think the answer lies in the form of an aluminum buick/rover 215.

if i can find some better pictures, i might be interested in replicating smokey's hot-air engine.

The Epica 2.5 is underpowered, not that reliable, and not that easy to find, or to find parts for even here in Canadaland. If you ignore all that and still want to forge ahead, keep in mind that this engine is set up for a fwd transverse mounted application and being manufactured by Daewoo, you're unlikely to find a RWD transmission that will be bolt up to this thing without some serious fab such as a custom bellhousing. If you get that fabbed up, keep in mind that often when using transverse engines in longitudinal swaps, the places for mounts and coolant hoses are usually somewhere between awkward and infuriating to work around and your exhaust manifold, oil pan, and accessory drive will be configured in a way that will likely need some modification, and that there is less than zero aftermarket for this car or engine to help you out.

If by some miracle you invest the hundreds of hours and thousands of dollars to overcome that and get this turd running in your Blazer, look forward to performance that almost rivals the anemic 2.8 V6 it likely shipped with, and having it down for weeks or months on end trying to find Daewoo parts for a car they sold about 12 of. It's overdone, but the answer for a S10 chassis vehicle is 4.3 (bolt-in), SBC (damn near bolt-in), or LS (tiny bit of fab work, but SO worth it). I know my way around these S truck chassis and engine swaps. The 4200 idea is cool, but will be a bitch. It's too long, packaged awkwardly for that application, and the oil pan will hit your crossmember (again with no aftermarket goodies available). It's also not especially desirable aside from the 'weird' factor. I really wanted the Atlas engines to be a star for GM, but they just aren't.
