4G64 Crank in a stock 4G63

[RED TREAD 97]

I've been reading around and I'm still a bit confused. I'm not looking in to building a stroker only because I drive like my grandma. I would like to rebuild my stock 98 4g63 into a strong, long lasting, reliable power plant. (I swear it's possible) But I'm not looking to stroke the motor. The OEM crank in my GST has a ready been machined to the point if no repair thus leaving me with no choice but to get a new or slightly used crank. I found a mechanic who has several 2.4 cranks for $75 and they are in very good shape.
Thru research, I've found the 2.4 is a 100mm stroke and the 2.0 is an 88mm stroke. What would I need to make the 2.4 crank work with out having to spend a ton of money for high performance rods and pistons? I'm only running an E316g, nothing that will require a race set up. Let me know what my options are and thanks for your time.

The 2.4 crank Requires shorter rods if you run it in a 2.0 block if I recall. Im not 100% sure though but I think thats all it really requires.

Close. You need shorter pistons. Rods stay the same size. You might as well get forged rods while your at it. It might cost $500 more but it will be a whole different beast. Or buy used for less

a 4G64 crank is what is used to build a stroker motor. it will require slight machine work to the block for clearance and stroker pistons.

So for my 2g (98) block, what work has to be done and can I have some specs or brands for pistons? The idea of a stroker is becoming appealing albeit a very expensive idea.

Just look at the classifieds if you're ok buying used. Otherwise just get on wiseco's site and look at 4g63 pistons. You'll need to have the shop see if your block needs to be bored then order pistons based upon that

And if you're getting forged pistons, get some forged rods. Eagle makes good rods. Also throw in some acl race bearings and you're pretty much set for 500+hp. If your goals aren't that high, normal bearins will work. When assembling check for clearance between the rod bolts and girdle

You're looking around $500 for stroker pistons and $330 for forged rods. I used the Wiseco stroker pistons, and Manley connecting rods in my 6 bolt 2.3L Stroker. I did not have clearance much at all in the block. I had to grind one a little spot in the block. Most people have to grind the main caps down, but since you have a girdle you won't have to worry about clearing main caps like a 6 bolt. I love my stroker motor. The next motor I build for a DSM will most definitely be stroked as well. They are great for DD'ing, more power off boost and it does help spool the turbo faster.

Or 750 total. That's why I mentioned used

rod journal number 3 will need to be clearanced for the rod, its so slight i did mine with a hand file. and dent the shallow section of the pan under cylinders 3 and 4 to avoid possibilities of the rod bolts catching the pan. i would personally use the kiggly main girdle and studs which would require a line hone, but for your goals you would be fine without.
good luck with your build, if you have and questions regarding the 2.3, let me know id be glad to answer.

i would personally use the kiggly main girdle

Is he making them for 7 bolts now too? That would seem kind of pointless, since the 7 bolts already have a one piece main girdle...

Exactly.

sorry, didnt see he was on a 7 bolt...
