6-bolt bottom end in my 2G?

[Gambit]

It seems like the gst has taken a walk on the dark side. Is it cheaper to swap a 6-bolt instead of having the 2g bottom end repaired? (if that is even possible) I'm assuming that you just take out the bottom end and everything bolts up to my 2g head and tranny/clutch. (minus the flywheel) What about wiring/ecu? and are there additional parts needed or can I reuse alot of the 2g stuff? If anybody has done this please give me some advice on where to get a 6 bolt and for how much, and how much to intsall, or is it basic enough that it can be done myself with the help of some mechanic friends.

is it cheaper? all depends the extent of damage on your block..

what in all needs to be done?

Each has its pro's and cons.

Once you get to tearing down and rebuilding an engine, the cost difference between a 6-bolt and 7-bolt gets real fuzzy. The cost will probably be close to the same either way.

does anybody know if the 2.4 engines have the same problem with crankwalk? If they don't, I was thinking that since I may have to go thru the trouble of doing this it would be coolt to have a 2.4L bottom end. Has anybody ever made a 2.4L hybrid? does it bolt up to the 2.0 head the same as any other?

Go to that Magnus link, they are building the 2.4 hybrids.

*cough* hybrid 2.4/2.0:

You *NEED* adjustable cam gears. the deck is taller so the relation between the cams and the crankshaft changes.

The 2.0 seems to make god power above 8500; coincidentally where teh tranny just doesn't want to shift "properly" anymore. The 2.4 can make nice power until 8200; so yo uwould stay in a good power band range with a rev and shift friendly car.

The 2.4 block is 7mm? (I think thats it) taller, the crank IS 12mm longer while the bore IS .060" more. I'm sure about the last two

The 2.0 uses a stroke of 88mm. I'm guessing the 2.4 is in the low 100's.

The main advantage of going with a hybrid is you can build it up as it is assembled. Metal head gaskets, 9:1 compression, and an mix of HKS 272 intake/264 exhaust cams can make a nice car. It will be more expensive than building up the 2.0 though; that I promise you. If yo uare on a budget just get a 6 bolt and go that route. No proness to crankwalk and in most cases a 33k mile engine beats a rebuilt one (do you have a shop in mind that you are *sure* can rebuild it properly?)
