2.2 or 2.3?

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.

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?

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

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?

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.

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?

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.

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.

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?

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/customer/product.php?productid=22035&cat=263&page=1&veh=2G%20DSM. Not to highjack, but is this one the same as the bastard 20g that slowboy used to sell?

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

As much as I love my 16g its like everybody has one. That's the standard 300whp turbo. Id like to get something that would set me off from the rest. The PTE series are nice but I dont like the idea of having to dent the water pipe to fit the compressor housing. The TDO5H 20g is a direct bolt on, but I also heard that it is more like a 20g wheel stuffed into a 16g housing which makes it more prone to heat cracks. I haven't read anything like that about any other kind of 20g turbo.......

Sorry to the original poster for taking over your thread. My buddy has a 2.3L 4g63 GST with a FP3065 and he is very happy with it. He says it spools like a 16g. I have yet to ride in it.

The 7cm housing on the TD05/TD06 20g will better suit quick spool and streetability.

I can't seem to find a TD06 20g anywhere for sale...can you tell me where to find them?

One of the first ones when I googled it.

Make sure you do a little searching before buying a TD06 20g, the bigger wheel is going to give you a slower spool. Also your not really going to see any gains unless your running 25+psi. Thats where the 05 wheel starts to restrict the exhaust flow to much. You could also clip the 05 exhaust wheel instead which would allow it to flow a little more.

So is there any alternative? A 20g turbocharger with a decent spool? I like the spool on my 16 now just the way it is, would be nice to find a 20g thats somewhere close...

Im not fluent on turbo talk as far as sizes and things like that, although im learning, lol. Ill get there someday.

Thats why some people like to use the TD05 exhaust wheel with a 20g compressor wheel, with that combo I hit full boost right before 4k. The car put down 340whp at 22psi. I choose to upgrade the wheel to a TD06 because I wanted to run about 28psi and try to break 400whp with that turbo. Shouldn't have been that hard if I wouldn't have torn it up. You could also go with an 18g turbo, it would spool a tad slower then a 16g but it would support more power.

Did you build your own like that? or did you buy it like that?

I bought it as a TD06 20g but changed out the wheels so I could use it with my current setup. Unfortunately this lead to the destruction of the turbo since the compressor nut came loose and f*cked it all up. Decided to call it quits with the 20g and upgrade to a holset turbo. Quicker spool and capable of more power.

Never heard bad on Holset.

That sucks(about the turbo destroying itself) but good to hear you got it all worked out.

Holset? Ill keep that in mind in the future if the time ever comes when I need to upgrade, which im sure it will, because im addicted to my car lol. Thanks for the help though guys.

By the way,if you dont mind my asking, which model holset do you have? I was browsing through them and was curious. I see where a lot of people pull them out of other cars...and rebuild them

Planning on getting the hx35 or hy35. Depending on which type of flange you are using you may need to get the BEP housing if you need a dsm flange housing.

oh ok, thanks

honestly, it sounds like you next step is the 400hp mark if you were alaready making 330. Your small 16g probably cant get you there the evo3 16g's can but are at the very brink of their efficiency/durability. A 18g and 20g will be able to get you there and considering they run mitsu housings are relatively easy to upgrade to. This is all assuming you stay 2.0L. You can make the 2.0L as fast as you want, depends how much money you want to spend and picking the right components.
