hey guys i currently have a 2.3 stroker and was thinking about doing a build you havent really heard of. i was going to get the 4g64 short block and use the heads off of my 4g63 with the 272 cams and stroking the 2.4 short block to a 2.7. if anyone has already done the heads on a 2.4 short block do the heads bolt right up?i dont plan on starting till after i get back from bootcamp when i have a decent sign on to play with but let me know what you guys think?

 

That would be so sick, full spool on an HTA35R at 3000rpm!!!

 

Its been done before IRC, but there isn't a whole lot of information and it was using the BC kit which a lot of people look down upon because the chinese used internals.

It would be cool to see someone do this with good parts and have it come out good. I would think it could put out some serious torque.

 

I though about doing it since my Eclipse is a 4g64. I just haven't figured out how much it will run me, and I would rather go FI before doing the head swap.

 

Its been tried/done, but not to any earthshattering results to my understanding. The redline on such a monster is compromised and the rod angles are so severe that its not a very desireable build in concept to begin with.

 

well i kinda figured someone has done it but never really heard of anyone doing it. since it has been done do you know where i can look to see some specs on what they did bc id hate to dump all that money in if its going to be **** ha

 

2.7??? I thought the highest was 2.4. I guess I was wrong. Hahah

 

the highest is a 2.6l kit from brian crower using a 4g64 block

 

And that 2.6L kit from BC (which I plan on using) isn't really 2.6L

It's 2,549.5 cubic centimeters. I'll give you that 1,997 ccs (our stock engine) is close enough to 2.0L but a 50cc difference is rather significant for the anally retentive (like me).

Never heard of a 2.7L (truly >=2,700 ccs) kit and would worry a lot of rod ratio & side load on the walls.

 

Say goodbye to high rpms.
Super-stroked, high revving, turbocharged engines = Fail.

 

This was one of the last ones I'd heard about:

The 4G64 swap is relatively common. Search "4G64 swap" or similar in the engine forum, google it too.

I chose to use the 102mm crank instead of the 106mm. This allowed me to increase my piston compression distance into a more desirable range and use a 6.000" rod (stock is 5.906"). Better combo IMO. I also kept the bore size just above 86.5mm.

 

I'm using a 4G64, but I decided to destroke it to 94mm. IMO there are diminishing returns when you consider the advantages to larger displacement vs. the limited rpm capability. 100mm strokes typically rev about 7800-8k. A 106mm stroke would be limited to around 7500, and that doesn't even account for the really bad rod/stroke ratio.
