i found a shop that will bore out my 18G greddy turbo to specs of a 20G. they said all parts will be replaced...basically a turbo rebuild. they will also resurface the turbo to make it all clean and shiny again. all for $500.
good thing about this is i will be able to just bolt it right back up to my greddy kit without any modifications.
good deal? how much more of a pull would i notice with a 20G over the 18G? is it even worth the $500?
jesus, 500$ is alot to spend on a turbo bore... If your looking to make more power I would sell your turbo and buy another one. I take it your running a greddy kit and "g" turbo's are dsm's so go to www.forcedperformance.com and select the green model DSM turbo. That would rock some balls!!
has anyone tried one of these turboes on a greddy kit im worried about fitment i mean the turbo is already close to the radiator? I think that you may be better off with a new manifold and turbo! but if these turboes will work that would save alot of money

Isnt the only difference between the 18G and 20G is that the AR ratio is +.02?? WTF would that do you unless you were running 20+ pounds? The 18G is rated to 400 and the 20G to 430. The only car that uses the 20G turbo is the 240. The 18G is used by the lude, integra GSR and base models, civic si, the 350Z and G35. The 18G is smaller, more efficient and a more capable turbo. If you switch you will experience more lag, undefined creep and the same amount of power at low boost levels.
I would assume that this process does nothing to remedy the cast 2" ID exhaust outlet on the turbo? If I'm correct, it sounds pretty worthless, IMO. Besides, just from what I've seen in person on the dyno, the 18G is great for the H22. I personally wouldn't go any bigger on a street driven lude, but that's me.
If that shop claims they can get the same performance as the fp green then go with it. I know that those 1200$ turbo's are not just basic 20g's though. They have larger wheels and compressor housing and all sorts of cool stuff.
To the comment about less efficiency and more lagg. More lagg, yes. Less efficient not necesarrily. How far do you plan to go with your lude? a larger turbo on 7psi will make a good amount more power than a smaller turbo on 7. Everytime I see an 18g dyno I always think no top end. I'm sure it pulls well but I want to feel it puling harder and harder higher in the r's. I'm curious as to what that fp green would do.
seriously though this is not just a standard 20g. and you could sell your 18g and put that toward the cost of the 20g
I have me doubts about the fitment with the greddy manifold and piping! It looks like that turbo would mount different, and there would be clearance issues unless you could get them to set the turbo up the same way as the 18g that comes with the greddy kit.

im sure the downpipe would be the same...yeah 2" i know sux. but as ghostlude said fitment problems. the greddy kit has about 3 cm from hitting the fan and about 1/2 -1" from hitting the alternator. by using the same turbo and boring it out i know for sure i would not have clearance issues.
as ludetech said, its about more pull than the lag. i rode in my buddies t3/t4 and was suprised to feel the continuous pull all thru 8k....amazing...something i never experienced w/the 18G.
Once i get my block back and get my motor all together, the next project is going to be a new manifold and turbo! With the greddy kit its fine at first but once u want more power especially top end its time to upgrade i think im just gonna change manifolds and turbos probably a SC61!

damn you people, you get to talk about your turbos and feeling the power from all this boos, al i get to do is read about all this glory and think about the last power surge i felt in my lude, and that was when i was pushing it home from the accident sence.... :JEALOUS:
The 18G is plenty of power. you can hit 350 wheels on it which is near 420 hp!!. you lose traction through 1st and 2nd at around 260wheels. why do you want to upgrade the turbo when you cant apply the power that the 18G produces? I say spend the money on an AEM EMS so you can manage the 18G properly.

I agree. Power drops off after around 5500 with the Greddy kit, but IMO that's more because of the lack of a boost controller (the boost also drops off around 5500).

oh its plenty for me as of now. i'm not changing setups anytime soon.
i dont get traction through 1st or 2nd as it is and i assume i'm in the 240 whp range. i'll have real numbers in the next month or two.
and i'm going with hondata as thats what the tuner here specializes in. but for now the blue box actually does a good job.
yeah im running hondata but i will be ditching the greddy kit probably by the end of summer simply because the motor im building needs a bigger turbo and i want to make 300-350 consistantly and beable to reach 400 with out a problem!!

, anyways.. they have a bunch of turbo's that will bolt up that will make ub3r l33t power.
