nice so do you guys actually think the stock internals can handle 400who or so???

CKurt3 · 03-01-2009, 04:23 PM

Oh, its an engine....

**Luke@BeyondRedline** · 03-01-2009, 04:23 PM

I really like the head design, but it does leave room for improvement. Also the sleeve depth is a lot more favorable for boost than other engines I have seen. I honestly do think that this should handle 400whp, it will just depend on how much you can get away with before switching to something higher octane than 93.

thats good seems like my goal is very feasable then, im aiming for around 300-350whp on pump gas for a street tune

Awesome! Thanks for the engine tear down pics. You guys are amazing!

Momin@EliteAutosport · 03-01-2009, 07:54 PM

Thanks for sharing. Looks promising.

Whats the bore? Planning on getting some 2.4l rotating assembly pieces together..

Seraph0503 · 03-02-2009, 12:05 AM

it's an 86mm bore x 86mm stroke i believe. square engine so should be good to rev to 8000 safely and smoothly. i think stock it revs to 7200.

Hmm...thats the same bore/stroke as the EVO X. Good stuff.

its the same bore and stroke as a lot of performance engines lol 2jzgte, K20 and more

Everyone's wonderd if the Evo manifold will bolt up to the head. Any word on that?

Galbi · 03-02-2009, 09:35 AM

I cant tell from the pictures but does this motor have any counter balance? The Automobile mag said that this motor does NOT.

This engine is NOT equipped with any counter balance shafts. I can't recall but does anyone know if the Chrysler or Mitsubishi cousins have them?

They dont either.

Mitsubishi 4B1 engine - Wikipedia, the free encyclopedia

this looks very promising... few things I can't tell from the pics though...

Rods... are they cracked cap or machined

ringlands look fairly spaced apart.. and I'm assuming that's a teflon coated skirt in the picture as well too. Anything else you've noticed that you can't really get a picture of? Like oil squirters, anything along those lines?

Overall though, I'd say we're definitely likely to see some 400rwhp cars, and the 300-350 range should be very safe on them. Really depends on if anybody unlocks the ecu, or how well it adapts to higher boost levels and the such.

there was a quote on here already from someone at Hyundai that said "while the ECU isnt easy to crack, if someone really wanted too they will" or something along those lines, ill try to find it

I believe it was a quote of John Krafcik and was something along the lines of;

It wasn't designed to be easy to crack, but it is not hard.

Notice this quote:

"Core components such as pistons and rods should move freely between them, for example. Hyundai’s engine uses a different computer, from Siemens. The software wasn’t intentionally made easy to crack, “but it’s not very tough,” says one Hyundai exec with a wink. That means up to 300 horsepower should be possible without major surgery."

Rods are Cracked Cap

Ringlands look spaced apart and boost friendly. The top ring is fairly low as far as new production engines that have to pass todays emissions are concerned.

Also this motor is equipped with oil squirters, and not the BS ones like the 2G Eclipse had.

Genecrosis · 03-02-2009, 04:07 PM

Are you by chancing putting the rods through any tensile strength tests or the such? You guys are actually going through and doing exactly what I wanted to do with ours in a few months (I want to build our car up through the standard bolt ons route to see what works best and how far stock components can be taken for less money).

Anyways, cracked cap rods aren't hateful. I still prefer a nice forged and machined unit, but the cracked rods worked very well in the srt-4's as well too. Thanks for the info though, I'll be sure to chuck you guys some electronics information once I get my grubby hands on our 2.0t :-P That's also going to be quite interesting on these cars imho, how the DBW reacts to larger map voltages, sweet scaling spots for larger injectors and clamping the map, ahh I can't wait to get to tinkering with a brand new toy :clap:
