is anyone using a T3,T4,T25 ect...does anyone know how well they go into the legacy turbo?is one better then another for the ej22t?i've been searching for a good upgrade at a good price on ebay and a lot of garrett's are on there.also looking into the mistu.tdo5 and tdo4,and the ihi v-series turbo's.what are those of you that have upgraded running and how was the experience?thanks

Hi-I have a T-28 turbo (60 AR and ball-bearing) that would work to about 20 psi on a 2.2; if no IC, I would`nt run it above 10-12 psi with stock timing. I love it for quick spool-up and upper rpm boost potential. I won`t know the total rundown on it until I get my Unichip and have some dyno work done. BTW, I have a 4EAT with 3:90 gears and a JMO convertor. The TD04 is supposed to be a good turbo also but I have`nt any personal experience with it. Usually you`ll need a different flange set-up if you go to a Garrett turbo. Check with a local supplier for the adaptation info. Good luck---Rod

yor waisting your time with that T28. The T28/GT28 series turbos were designed for quick spool and outragous rpm levels of the Honda 1.6L and 1.8L engines. Using such a whimpy turbo on a 2.2L is just not the right idea. The TD05 doesnt spool near as quickly as stock but it does pull very hard on top... i know becuz i swapped one into "Frmrgs2rchs" car. If you wanted to stay Garret then the better choice would be the GT30/T32. These are made for engines between 2.0-2.5L and will allow a 7500rpm redline to stay on the compressor map. Theywill not spool quite as fast but are good for much more horsepower on the top of your power band.

I was curious about the comment that the GT28 was too small for my 2.4 motor so I called an expert/Garrett distributor. Here`s the correct info: there are 3 different T28s and make the following HP dependent on modifications-T28R (mine) 280-300 hp--T28RS-300-330 hp and T2871R-400+ hp (next turbo after Unichip.) The 71R has a slightly different flange for the DP, so it`ll have to be changed. It seems the AR (simply how quickly the turbo spools) is`nt much different among the 3 so any of the 3 should work well with my auto and 3:90 gearing. BTW, they`re all double roller bearing turbos. Just some info for the "turbo-thirsty"--Rod

hold up now i never said they wouldnt work, i just said that they werent really designed for a larger displacement engine. You can swap out comperssor wheels to fit it to your engine but its costly, timely, and takes some skill and i never automaticaly assume that people know how to rebuild turbos.

Theyll make the horsepower, but for anything above a 2.0L i would expect nothing less than the potentail for 450hp from a turbo. I have a 2.4 DOHC in my Z24 and a T28 is just too small, it would spool too quickly. A more proper fit would be a T3/T04S... spools at 3000revs and still has the potential for more than 500hp. Its not BAD to use a small turbo however youll have a lot more trouble breaking 300bhp barrier. IF your not interested in doing so then i suppose a T28 would fit your taste. Though i still recommend the TD05 (small 16G)
