Possible to use the JUN stroker kit in our 4g63s?

[Hobbes =^.^=]

I was taking a look around and they have a stroker kit available for the EVO 4g63.

From what I read, the early EVO engines are very similiar to our USDM ones. If so, wouldn't it be possible to use their stroker kit in our 4g63s or if you managed to pick up an EVO III engine? and have a 2.2L?

Just a thought that came into my head. What are your opinions or thoughts? I don't really know is this would be of any benefit to us though.

why not just use a 2.4 crank from a spyder? Its much cheaper

where in the site does it say that it is for an evo? It just says 4g63. It looks like it should work for our cars but dont take my word as the final one.

One of their cars is an EVO V. So I was just assuming there.

The kit comes with a JUN Full Crankshaft, JUN Super Pistons and JUN Super Connecting rods. Just wanted to know if it would benefit us at all, since they use that same kit in their EVO V.

how many HP can the rods hold? crower makes rods and piston heads for our 4g63 engines. both 1st generatiom and 2nd. I know the crower rods can easily hold over 600+ hp.

I'm not really at all familiar with JUN. So I don't really know their specs and such. Just wondering if anyone else knows anything about this product.

I know there's other products out there. I just found this kind of by accident, and seeing if it's any good. I heard that they make some really good things, and have some very nice cars.

For the money the JUN would cost. You could buy a 2.3 stroker kit from www.ffwdconnection.com and have money left over.

While were on this topic. What is the main difference between the 4g63 that's on the EVO Lancer, and our Eclipse, Talon 4g63's? To me... I would think it would be the same since there calling it a 4g63, except for maybe it has a bigger turbo or something. Any thoughts?

the lancer evo I-III had the engine facing the same wasy as ours. the evo 4-whatever number is out now is rotated 180 degrees. I think they had different injectors and turbo. and maybe exhaust manifold or o2 housing or something like that.

That's cool then. I knew that one of the evo's had the motor turned the opposite direction, but I figured it was because it was a right handed driver. I was just curious if the internals such as the rods or pistons, and maybe the compression was a little different in any way. Thanks for the info!

The EVO I-III was basicly the same as our DSM engines. They were even prone to crankwalk!!! Mitsubishi redesigned the EVO heavily for the IVth release, they turned the engine 180 degree's maintaining the clockwise rotation and allowing for the tranny to be placed on the drivers side (passenger side in Japan) for better weight distribution. and the other large difference...TIMING CHAIN. That's right boys and girls, chain.

If this JUN kit was designed for an EVO I-III it would work on our cars, but a IV and up wouldn't. Also, why use the JUN kit over the 4g64 crank in the FFWD kit? Well, you get a shorter stroke and longer rods giving you the same wonderful stroke/rod length ratio as the stock 4g63. The 4g64 crank is such a large stroke you really throw the rod angles all out of whack. A better alternative to FFWD and JUN...Crower. Custom BILLET crank and custom LONGER rods maintains rod/crank angle and improves strength. Plus for a little more you can upgrade to titanium rods.

Great info man! Thanks!

How much more hp do you think you can get from making your engine from a 2.0l to a 2.2l or 2.4l?

Alot more torque and broken drivetrain parts.
