To Stroke or Not To Stroke?

[InfiniteGSX]

You both gonna go on green

Yeah that train track is exactly a 1/4 of a mile from here. I used to race back here in high school!

I've never reved past 7k I belive. Well atleast with this 97 I haven't. For some reason unlike my 98, it has a rev limiter I belive. I don't ever remember my 98 having that issue. Cause I've noticed alot when I would race or just do some good ol fun heavy accelerating that there is a limiter around 7.2k or so. I hit it very fast in 1st gear...

... We could always just race like Neons do it... FROM a roll!

Man I'm still trying to cope with the fact I cand just give her rev to 7k slip it fast as hell and floor it at the same time

But yeah the one thing they didn't bring up is that the torque becomes more evident when you have a turbo app. In a NA setup the added torque would be noticable but nothing earth shattering but in a turbo setup it can get pretty crazy depending on the mods around it. Even though it's not directly compareable I have seen a 4g63 laser awd go from hooking with a chirp to lifting the front tires off the ground maybe 6-8 inhces or so after a stroker build.

Aren't there guys on here with stock 2.4l engines just ask one of them how it feels and if it's worth it. I think it would be a waste of money for a all motor setup and if yoru gonna go turbo it's def worth it cause your gonna have to forge the bottom end anyway.

are u referring to after market parts in this 2.4?

2.4(as long as compression ratio is the same) it's not gonna matter if it's stock or not. Forged pistons don't make any more power then stock. Now if the motor has cams raised compression port work ect. then it's another beast. My point was for people lookingto do a basic engine build (stock 2.4 or maybe just slightly higher compression pistons, rods but everything else pretty much stock) Your gonna end up running similar to a basic 2.4 eclipse.

I'd rather build and keep my current motor then use the motor from another car to make the power I want. I dont want to have to relie on a SRT or PT Cruiser to make power. I mean the SRT4 motor and the Eclipse 420A are like sister motors anyways. Just, the SRT4 is how many years newer in technology advances and built stock for boost when our 420A's aren't.

im the same way and thats why im sticking with the single cam that came stock in my car.

I'm confused right now.

Primarily because more then half the poeple on this forum are always looking for more and more, then evebn more power. I constantly see 'need more power' or 'power upgrades' threads from members trying to squeeze that last HP from thier car.

So, now, when you are actually puitting some money into the car, and generally setting it up for more power, they don't know whether to stroke or not to stroke.

Now, look at this way, you're spending $2000 atleast in the block and internals alone. This is for a 2.0L DOHC engine. For the extra $300 you can get a 2.2L motor. 2.0-2.2= .2 over 2.0. Overall, and technically speaking, giving you %10 more power.

10%? Yes, 10%.

If you ask me, everyone doing an engine rebuild should stroke thier motor. You can get 10% more power for only a couple hundred more dollars!!! Why wouldn't you stroke it?? If you're willing to spend $250 for a 60mm TB to see 4-5WHP gain then why wouldn't you spend $300 for , atleast, a 20HP gain?

I'm all for the 2.2L.

We had a huge debate about this when I was 4g63 in the threads but in a nut shell some of the arguments were if it were the best way to go for overal power and reliablility which you have to keep in mind, why doesn't shep use a 2.3/4 and why do most of the guys at the top of the 1/4 mile and dyno list use stock displacement high reving motors? Two things I see as a downside to strokers (and by see I mean first hand or threw guys I talk to directly not internet knowledge). One traction if you have a car that is barley getting traction with slicks then you ad a stroker your beat. In this case you actually go faster with less which in the end is all that really matters cause we're not supra owners. Second and more importantly is reliability. Increased rod angle and changing rotating assembly specs seems to always equate to more often maintence. Many guys have good luck with strokers but more often then not you have people that go threw cranks which is not something you want to be changing every however so often.


However more power is more power and I have to be honest I would probably stroke it and cross my fingers nothing breaks.

 

[Blitzeclips]

If it's done right, it shouldn't break. Period.


As for traction issues, yeah I can see that but you need to realize low-end is what gets you off of the line. You don't necessarily have to drop the clutch and go, if you ease onto it the resultsmay be better depending on if you can drive or not. If you ask me, low-end power will help you more then top end power.
