Taking machine shop class need help with first build.

[gusu]

Since I am going to be taking a machine shop class and need to learn how to rebuild, port and polish everything I am looking to build an extreme motor.

I have read some stuff about 2.3 and 2.4 liter strokers but they all seem to have totally different "opinions about what is good and what is not.

I have heard more bad things about 2.4 than good but everyone who is going fast is all running a 2.3 from what I have read on here.

Anyway I was wondering what I should build. I might sell or just hang onto this motor for a future build.

I am really leaning more towards a 2.3 and am wondering what I should know before buying parts for the build.

There are 2 different setups for a a 2.3L stroker. A 7-bolt one starts with a 4g63 block and uses a 100mm crank out of the 4g64. You can also do a 6-bolt version using a g4cs crank in a 6-bolt 4g63. You use the connecting rods from the 2.0L engine and pistons made for a stroker. Several vendors sell kits that would give you all the parts you need.

The 2.4L isn't a stroker. It's either a 4g64 (7-bolt) or g4cs (6-bolt).

There is a 2.6L stroker though. It's a custom package through BC (that's the only one I know of) that uses a 4g64 block.

Sweet thanks for the info. I'll probably go with a 6 bolt then.

What about the head? I would like to do something high reving but I don't really know much yet is there any down sides to a high reving stroker? Plus what are the limitations and what would I need to get there?

Here is a pdf with all kinds of good information about what goes on in a 4G63 engine with different displacement configurations. It helped me greatly when I was deciding to build a 2.3 or not.

Also I just stumbled on this thread and I think you might find it interesting and helpful even though it is an Evo engine.

you understand that you have to be crazy to even work on cars... and just totally insane to even be a machinist??
