Isn't the to4R like almost 6k and the gt 35/40 only 4k? They can both produce 500 at the flywheel. I also heard you can't rebuild the to4r in the states? And you can get the cartidge or parts for the gt, so all in all i think the gt 35/40 would be a better choice, esp for a street car.
the to4r is a normal standard shaft garret style turbo, nothing more, so the overhaul kit from turbonetic's is around $80-90 and you can buy standard p trim exaust wheel / shafts for cheap as well. The only thing special is the a/r 70 compressor housing and blade that is 66.8 mm on the inducer and 84 mm on the major. I'm pulling off my to4r in the the near future because I just picked up a T70 turbo that should be on the car in the next few weeks.. it has a a/r .84 compressor, 70 mm inducer and 98 mm major.. any bets on how long the engine lasts.. :yum:

I wish I had some $$$$$$$$$$ so I could take that t04r off your hands.



I'd like to see some spool time comparisons between those 2 turbos though.

So what else is needed? dowel pinning? Thats kinda like 3mm apex seals from what i have heard, cough* not needed...
you just need a good set of 2mm seals a good port and you need to work on cooling the rotors down by putting carb jets in the e-shaft and make sure you have good bearing clearances... lots of power makes lots of heat and that will make hot spots and those cause detonation. Any time you make lots of power regardless you will shorten the life of the engine by a group. On a stock internal engine with stock ports you have lots of back pressure, this limits the hp and it creates a **** load of heat that can't get out of the exaust port this creates very dead engines very fast, ie. sock 13B's arn't going to last long with over 400 hp..

I'm keeping the exaust a p-trim with a a/r 1.0 housing and with my exaust port it should still spool pretty fast, the only thing thats going to slow it down is the heavy *** frisby in the compressor housing trying to pick up speed.. :yum:



lol.. I already sold the to4r to supliment all the crap I need to put on the T70.. I also have a back up to4r that I'm still keeping just in case I kill the new smurbo...

Yep you just need a standard shaft garret overhaul kit, it should come with a rear and front seal, 2 shaft bearings, a thust bearing and thrust coller and the c-clips that hold the bearings in place... you can get them from almost any turbo sales place or from turbonetics..
