2.2 or 2.3?

[boostjunkie333]

I wanted everyones opinion on something, when I begin the rebuild here in January, i'm going to have the block machined, and I wanted to either bore it to a 2.2 or a 2.3, ive heard good things about doing both to eclipses, advantages and disadvantages, through researching on the forums. Can someone lay out the facts and help me decide which route to take? Which might I be happier with in the end.

What do you mean bore it to 2.2 or 2.3? That would be the stoke, not the bore. Boring would be 0.020" or 0.040". If you're looking to stroke the motor to 2.2/3 you need a different crank, pistons & rods.

As for the facts, a stroker will spool a turbo quicker than a non-stroked motor.
However, a non-stroke will be able to rev up higher.

[boostjunkie333]

Yeah stroke I mean,

I just cant decide if I need that extra power or not. Whuile I have the engine, and the money to do it. I already have right much, of what benefit would lets say making it a 2.2 do for me...realistically?

[SilvrEclipse]

The only reason people stroke their motors is so they can spool up big turbos faster. This is entirely up to you. Do you want to spend more money on the build and run a huge turbo wanting to make lots of power

[boostjunkie333]

Well, the last time my car was dyno'ed was over a year ago and it was 330hp and some change, how much more can you go before its too much power? Is 400hp far fetched? Could I make this goal without going stroked? Im having trouble setting a goal...Could someone tell me the limits that are pushed on our cars...so I can shoot under it?

[boostjunkie333]

Btw im talking mainly about dragging purposes...so, whichever setup might help me with quicker times...is what im looking for.

I just read that 500 is about the limit...so maybe if I ever purchase the 20g and sell my 16 then maybe I could work towards making that amount someday, so im looking for whichever alternative will help me in the long run as far as engine work.

If your going to make it strictly a drag car then you have to consider that something like a 2.3 will help you spool a massive turbo off the line but it won't be able to rev as high as a 2.0 would for the top of the track. I stuck with a 2.0 on my build and an 18g with a ported out head with larger cams so it should be a good combo for low end torque but still be able to do decent at the top end...

Of course everyone does things different. There are many setups to consider. I've seen some people with some ridiculous track times using nitrous on only a semi built 2.0 motor. It's all in how much money you want to spend in the long run.

[boostjunkie333]

So, most of the power I want to make can be done so without spending the extra money to have it stroked? Thats pretty much what I was trying to decide. Thanks for the help!

You're switching to a 4g63?

[SilvrEclipse]

The limit of your motor depends on what parts you built it with. You should be fine up to 600+ hp. Now I dont know if I would push it that hard but it should be able to handle it. I run a 20g turbo and with the td06 exhaust wheel it gets full boost around 4500 its pretty laggy but it does help out with traction in first and second gear some. That turbo can easily make over 400whp if I cranked the boost up on it. If your planning on using this car as a drag car then I would suggest you learn how to drive it on lower hp before cranking the boost way up and making a lot of hp. Get you some slicks and get your launch down first, the 16g can put down some good times with slicks.

[boostjunkie333]

Yeah, Im used to driving it at 19lbs right now so, and itll sail when it reaches that, so I think im ready to get a little more out of it next summer.

I have the hahn kit, 16g, so if I upgraded it would obviously probably be to the 20g that hahn also makes, which im guessing would give me all the power id ever need for that car? Im trying to decide if I want to go head and upgrade my turbo or if the 16 will do for now. What all would be involved when I take the step to upgrading the turbo to the 20? Supporting mods I mean...I know this is a bit of a vague question, but just kinda wanna know what im looking at, so a simple explanation will suffice lol. From what I know, at this level it becomes a matter of going up in injector sizes and tuning for more boost in order to make power, up to your limits? Please correct me if im wrong...

I do appreciate everyone taking the time to answer such questions...

Hahn's 20g uses a 10cm housing that is purely retarded.

You need fuel, logging, and tuning for the upgrade.

[boostjunkie333]

Ok, I was just making sure. And all my questions have been answered except for what you just said about the 20g upgrade...so stay away from it?

[TalonEclipseMixGsx]

I am also wondering about this. Is a 10 cm housing too big or too small? I was also looking into a 20g and found this one with a TDO5H housing that is 7cm. http://www.extremepsi.com/store/cust...1&veh=2G%20DSM. Not to highjack, but is this one the same as the bastard 20g that slowboy used to sell?

[ned032002]

I bet that 20G is amazing! My buddy had a Bastard 20G from slowboy, that was insane at WOT.
