Im just trying to get the size of the stock 2g exhaust impeller or if someone has it the diameter of the cartridge itself. I have come across a garrett turbo that i am planning on installing to my 1g.It has a ball bearing center section i just need to find out if i can just bolt on the 2g housing without doing any machine work.The turbo came off of an izuzu diesel.I know its a crazy idea but the turbo is in excellent shape.I just wish i could find out what the frame of the turbo is (looks very similar to a gt28r just with a different exhaust housing)If anyone had any info on this turbo or if you know where i could get specs on it it would be reatly appreciated.

Sorry, don't have any T25s handy to take measurement, but I can alsmost guarantee that whatever you have will have much bigger exhaust wheel compared to T25. Bullseye housing maybe?
 
It is definately a bigger exhaust wheel than a t25 its actually only a 32nd smaller than a big 16g 7cm2 but the cool thing is the compressor wheel is almost the same size as a 20g's therefore im hoping it will provide the same cfm as a 20g but with the same spool up characteristics as the big 16g im not sure how its going to work just curious to see what kinda numbers i can get with it.we only have an 1/8th mile track around here so i hope i can get it done when the track opens.
