Ok I am going to star slowly assembling the parts for a 2.1 build and figured I would start with the most important part first, the block. So I know there are several vehicles that ran this block. I know that one is a Kia. Question for this block, and all 2.4's for that matter, how do I know I am gettiing the right generation block? Anything in particulat to look for? Markings? The casting number on the one I found locally is G4JS and 1067481. I know the G4JS is their number for the 4G64 but I am hoping one of the guru's on here might be able to see something in the other number to tell me if it will work. Or what I can look for. Thanks in advance!!!

 

no one?

 

Call slowboyracing... I don't think many people have more experience with the 2.4 than them.

 

So you are looking for a 2.4 specialist and you are building a 2.1? I realize they are very similar, just trying to clarify.

 

think he is using the 4g64 block to create 2.1. im guessing he wants to maintain high revs. should just make LR2.4 and be happy.

 

I agree with Rockman, I almost when with a LR2.4 but I felt dirty getting away from the 4g63 block for some reason lol

One of the big advantages of the LR2.4 is it doesnt have as aggressive of a rod angle as the 2.3 and you can rev it pretty high.

 

Not sure what it is about the 2.4 I don't like, but that is not what I am looking for. Yes I am using the 2.4 block to destroke to a 2.1. I want to be able to rev to 9500 or so. Also with the super low rod/stroke ratio the wear on the engine will be less as well. I guess I will PM slowboy and see what they say.

 

The 4g64 block can be found in a 2000-2005 eclipse or 1999-2003 galant. There a dime a dozen.

 

there u go

 

there are many more than that

 

If i remember they were also in the hyundai Sonata,and chrysler sebring....

 

Have to be VERY careful on this one. Not all Sebrings/Stratus have the Mitsu motor. Some of them use the 2.4L 420A (not sure on the code) Neon style motor. I am not sure I would say SBR is the only place that has lots of 2.4 experience.

 

i gave you credit for a place to get 2.4s in another thread. I gets no love from english racing team. I know i dont live in that area but dang its like that hommie.

 

Rock,

Nahhh its not like that. I saw you gave us credit in the high rpm 2.4 build thread as well. That comment was directed at another post in this thread actually

 

Well, I know I tried to get in touch with you guys when I was looking into a 2.4 build but you never got back to me so I ended up talkin with slow boy.

Granted I ended up going with a 2.3 from Buschur but I did a lot of talking with Oliver over at SBR during my decision process and hes a smart guy. If I was going 2.4 I'd go with SBR.
