+ on the 16G, once you start really getting a hang on how to drive the car with a faster turbo, and give it the proper supporting mods, upgrade from there, but the 16G is definitely where you need to be at this time

 

Dont upgrade til you max out your t25. Get your car breating good first (intake Exhaust) then do fuel (ie 550's or bigger depending on what you want) get all your gauges (boost, egt, A/F... etc) by then you should be maxing out the full power of your t25 then and only then you should upgrade your turbo. do it right dont just through on a bigger turbo and go. Also once you get the bigger turbo your gonna need a inter cooler and piping... etc so you have a long way to go before you should upgrade your turbo.

 

fp green is a kick ass turbo

 

^^^ With the right supporting mods. It isn't the most streetable turbo, but it is killer for high speed races or roll ons. As others have mentioned, with out the supporting mods, you won't be able to run the turbo to its full potential. With the FP green, you are going to probably going to have to get some stronger connecting rods, springs/retainers, etc. to get the full potential out of the FP green. Head studs and the balance shafts removal would be a good idea too, if going this route. If you don't have the desire to put all this extra work in, or don't have the cash for it, I'd suggest you go with the Evo III 16G, since it is capable of making as much power as the FP Green (without the proper supporting mods).

Alot of DSMers always have it in their heads that have need the biggest turbo possible to be fast on the streets and at the drag strip. 99% of the time, the Evo 16G suits these people perfectly.

My 2 cents...

 

Man any kind of turbo is better then the t25, shit throw on a 14b for $100 then go with big 16g that u can usually find for under 300. trust me 16gs are great street turbos. You wont be dissapointed.

 

a little misinformation....an FP Green is VERY streetable, it comes on very smooth, and packs a punch like mike tyson, full boost no later than 4000-4100'ish, and will not make enough power to blow your stock bottom end unless you are running insane boost with some huge cams, however, it will require a front mount, at least a 3" exhaust, injectors, pump, afpr, a fuel tuning apparatus, guages, datalogging, and basically every other conceivable bolt-on...a 16G you can get away with the basic bolt-ons and still run good....

 

BOLOGNA!

You do not need stronger anything to run a FP green to it's full potential. The FP is the perfect turbo for a 6bolt motor in stock form. FP greens have gone 125mph with stock cams, which is about what people are seeing with the "all so awesome SCM61 turbos"(makes jerking motion). If you don't know what your doing then stick with a 16g or even if you do know what you are doing. A 50trim turbo is something not to mess with lightly. Note the video of the 2g gsx blowing its motor because he decided to throw on a fp green without suporting mods.

BTW stock 4g63 heads have seen 8500rpms with 272/272 cams in them plenty of times with no problems. No need to upgrade them unless your going 414s or over 8500rpms imo.

 

I'd go with a Super 16g, being the equivilent of a standard 20g its a pretty sweet deal..just hope you have all the necessary piping.

 

Do NOT waste your money on a super 16g. Look at the numbers btwn an evo 16g and a s16g/20g and you'll see what I'm talking about.

You people are thinking into this way too much. Just get an evo3 16g and you'll be set for quite a while.

 

im running a 17c, its a great turbo maybe consider it. its a little bigger then a evo 16g. Im trapping 102+ with stock exhaust and boost on 15 lbs. and exhaust leaks-everywhere.(02gasket, broke stud in head-not extracted yet.,dpgasket)
