As a general rule of thumb. The 2.3 usually makes around 100hp give or take more over a 2.0 on the same setup. Also makes more tq like i said. But it really depends on what you want to do with it. The 6466 spools 30psi by about 5500 on a good divided t4 setup on a 2.3 I'd expect it to be around 5100.

I have a friend on a 2.3 with the 6466 that drives it on the street with only pump and meth and has had the car up to 50+psi @jery1234 but hes on an auto, and a mad scientist

In the end it's all your choice

be running on E85 as its pretty easy to get in Ohio. i just want to make sure i will be able to get to about 40 psi thats where i am looking to be at with the turbo anymore will just be a great plus and yes i will get a great boost controller i have a electronic one and i was looking to switch to a manual.

Are the revs that much better is the 2.3 fun to drive what psi are you at?

On my old 97 GSX: 2.3 6262 JB. Driving around town was a blast with the 2.3. power always felt on tap. And that's what I wanted.
Really depends on how you use your car. Mine was a weekend warrior, highway pulls kind of car. And at the time the 2.3 was new an exciting to build. I over spent my money and could have hit the same power for about 1500-2000 less.

I now have a 99 GSX with 6262 BB on a built 2.0. Excited to see what she can turn out power wise.

yeah my car is defiantly a weekend/nice weather warrior. I have all hood exit exhausts. Thats kind of what i want i want to feel like power is always right there i step on the gas and she starts to spool and get moving.

Like i said, Some are lucky, some go through 12 even on a 2.0

Start going to the track every weekend and you'll change your tune in a hurry.

I've thought about making my next motor a 2.3 with my T3 HX35. I imagine that would be a fun weekend warrior.

my next question would be what cams should i go with im really on the fence about this as well. This is if i went with the stroker option. I was thinking bigger intake and a little smaller exhaust.

About broken transmissions? I dont see what you are getting at, i said some are lucky and dont break transmissions as often as others. Some guys have gone through 6-12 transmissions... And i believe the 2.3 will go through a trans quicker then a 2.0 on the same setup. Thats just my opinion and justifycation for staying 2.0

I have heard our transmissions don't like the torque but I think I'm going to play the odds that torque in a 4 cylinder seems like so much fun

I'm not saying dont do it, just know everything

When you push your car hard it simply breaks trannies. My car is a 2.0L and I pretty much go through a tranny every year and I barely track it.

What?? Maxing out the same turbo, a 2.3 and 2.0 will make the same power. 2.3 will make it sooner, and thus more tq. 2.0 will need more boost, but they will "generally" make the same horsepower.

but if your maxing out a turbo, the 2.0 doesnt have any more boost to go. I guess you can't REALLY compare since 2.3 requires more air and the same cams that would boost performance on a 2.0 would hurt a 2.3. I'm not set in my ways, thats just my understanding. Displacement will always make more power

Here is an excellent article on stroking the 4G63.
http://www.speedperf6rmanc3.com/content/StrokeOrNot.pdf

It's 60 pages long and covers HP, Torque, Friction, Cam timing, etc.

Jim

Just so everyone knows the comment on the previous page about a longer stroke 2.3L engine making 100hp more than a standard displacement 2.0L is completely false. I have built enough of these things and been at the track and dyno far more than most of the people in this thread combined and it just is not true. Depending on the setup they will make the same horsepower and could possibly make more torque up to a point. Big turbo cars will still have high horsepower and low torque.

So for the new guys, a stroker absolutely will not make anymore power or torque. It usually will make more of both at less rpm by moving the curves to the left because of the displacement. With large turbo cars to me that act exactly the same. I attribute it to living at 6000ft mostly. I honestly feel any of the small displacement Sirius engine based cars feel and act the same. At the end of the day it is a tiny four cylinder.

I vote for a standard 2.0L ten out of ten times. We have needed rpms on nearly everything we build (straight line cars) and have beat the bearings out of 2.3L setups a few times now trying to keep the turbocharger shaft speed up and efficient. Unless you stay with a 45-55mm turbo you honestly will not see any benefit in low end torque and response. A big turbo is still going to be lazy. It is just simple math from utilizing a small engine.

Does your boy Jery have s build thread. I would like to see that setup and magic

Click to expand...

Not magic at all . Before this happened it was (Mahle 10.5:1 cr 2.3, eagle rods 1mm over valves, 6466 top mount 1.15 ar ts ,hks 272 , 1600cc 3 nozzle pure meth injection , tuned for 42-50 psi, revving 9-9.5 k rpm for past 4 years . Nothing has changed exept the rods now 300M . You can see the bearing on the picture after 4 years of abuse . With my setup I see 44 psi @ 6 k rpm .

30psi to make 600hp on a 2.3 liter may take 35psi to make the same hp and generate same flow on a 2.0. Both maxed at 600hp ~60 lbs/min. Explain how a stroker somehow changes the flow rating of a turbo? We aren't talking about going from a 4 cyl to v8, just a 15% bigger engine.

Oh and BTW, take a 100 lb/min turbo that will make 1000awhp on a 4g63, and see what it will make on a small block chevy or ford.......cheat sheet...LESS. Yes, that is right, a 5l-6l V8, using the same turbo will make less power than the 4cyl. Displacement will NOT always make more power if we fix the turbo size, which is exactly what this discussion was about.....a 6466 turbo.

And what he said just adds to what I said above. If you have a 400ci engine or a 1.5L Honda and strap a GT35 on both engines, you are only going to make a potential 600hp for both. You are limited by what the turbo has to offer. No two ways about it.

So if you take a chevy 350 and stroke to 383 does it not make more max hp? Or does the turbo literally limit max hp and thus the example isn't the same?

No engine makes horsepower. They only make torque. Horsepower is a byproduct of torque and just a marketing term.

And your turbocharger is now your restrictor plate. It can only flow so much air regardless of what is behind it.
