Which Stroker: 2.2, 2.3, 2.4, or 2.7?

[98TsiAWD]

Well Im currently seeking out a few cars I can buy for $2-300 bucks, fix up (clean, head gasket replacement, stuff like that) and sell for $1500-2500 each. My did this last year (he owns a mechanic shop) and made anywhere from $1-2k per car/van by puttin 2 days of work into each vehicle. So I want to find about 3 or 4 of these and have it all done by the end of the summer. The whole reason for this is to get a stroker shortblock, stage 3 BJ's head, and a t3/t4 setup.

Now I could go all out and get the new 2.7 stroker, but is that necessary? It would spool the turbo up like nothing, but my guess is the 2.7 would redline pretty low, like 6-6500 rpms. Meaning ALOT of shifting, so maybe wouldnt even be any faster than a 2.4 in the end?

The 2.4 obviously is a good setup as lots of people are running it. The thing I like about the 2.4 is I can still stick with a 7 bolt with the 4g64 block.

Then theres the 2.3 from FFWD connection, still a 4g63 block with their custom crank/rods. This would probly rev just a little bit higher, but the downfall is I have to go through the 6 bolt swap.

The 2.2 JUN stroker I dont know much about, but Im willing to bet it cost more than any or the others for less displacement.

Lets here some serious input on this, I want to know which would be the best for the 1/4 mile and a Daily driven street car.

They make a 2.7? That would seem like it would excessivley long stroke.

You may want to talk to crankwalker (PBC) about the 2.7L before you dive into it. Myself, I am built a 2.4L.

i think the 2.7ltr engine would be best for 1/4mi, hands down. but 2.7 does seem a bit much for a 4 cylinder. I'm guessing the overall engine life would be much shorter than any of the other choices. I don't really know for sure, its just speculation because i am no means an expert on this and i haven't really looked into it, at all. but yeah. its up to you.

 

[out there]

you've got to be kidding, a 2.7? where is this available??? man, you'd probably rival a small/med truck for torque!

Crankwalker from NJ? Ive talked to him before if thats who you are talking about, did he buy a 2.7 shortblock?

 

[autronicDSM]

2.7 is on indefinite hold. Go find a thread that I started on PBC. Owner of it said that he has to find a new supplier for his custom crank so there's no 2.7 stroker for now.

I believe Mark is from Nebraska or Iowa or one of those corn states. Yeah, Nebraska, thats it.

I too want the same things you do out of my car. I decided on the 2.4 over the 2.7 because of cost and the redline you mentioned. I didnt chose the 2.3l because of the needed 6bolt swap it just wasnt cost effective to me. I also eliminated the 2.2 stroker for cost alone. I guess the finial deciding factor was the fact that I found a 4G64 short block for 75bux.

I have kind of decided the same thing, 2.7 would redline too soon, the 2.2 is JUN so in other words $$$'s. The 2.3 is nice, but like you I dont really care to do the 6 bolt swap. I am looking for a 4g64 7 bolt block and will be going with the 2.4. Now I just need to do some research to make sure I am buying the correct parts.

i don't really believe the redline can technically be "too soon"... unless you're speaking purely of personal preference

 

[xinfiniter]

I got the 2.3L and did the 6 bolt swap. Cant say anything bad about it.

sure it can
higher redline = more horsepower, basically

there's a big tradeoff between stroke length and redline. as stroke length increases, displacement increases, so torque increases. redline decreases.
as redline increases, horsepower increases high in the powerband.

i always thought it was silly to stroke an eclipse. its turbo, so the high end has plentiful torque, and the high redline just means more horsepower.

now if we could bore the suckers...

 

[autronicDSM]

Why do you think you have to lower your redline when stroking? Just make sure you use rods that are strong enough to rev up to 7k or 7.5k. You're building up the motor so it only makes sense to go with forged internals.

Well that can be debated. If the car could be geared properly to compensate for the drop in redline then i'm sure the gain in torque could be put to good use.

 

[autronicDSM]

yea anyways... are you going to come up with new ratios and make gears and sell them for cheap? don't think so

 

[talonted_one]

well talk to Marco at Magnus. He says he can rev to 8.5k no probs, but that is of course with a built head.

Who says you have to swap in a 6 bolt? Drop in a 7 bolt 100mm crank with stroker pistons and you're done...

yes, but to avoid CW he would have to swap for a 6-bolt, the 4G64 2.4 supposedly will not CW...

no but i was making that statement in reference to the person i quoted because they were saying how a higher redline = more horsepower... and he went on. i'm just saying that doesn't mean much. too much emphasis is sometimes put on horsepower alone.

 

[DSM mechanix]

personally, i should be doing a 4G64 stroker this summer.

do whatever u feel suits your needs/ambitions...

i agree. If horsepower lied in readline only, then wouldnt a turbo honda be king

its about finding the best compromise for you...

Ive decided on the 7 bolt 4g64 bottom end. This way it can still handle 8k rpms, but I will probly set the rev limiter to 7500 with the dsmlink. And it will spool a 50 trim probably before 2500rpms

Are you talking about full boost or when it would start spooling? A 2.3L stroker typically knocks off 300-400 RPMs of spool.
