While i'm waiting for my new turbo to come in is it safe to atleast commute to work with a bad oil seal in turbo, I mean it smokes mostly when I let off gas, and shaft has minimal play seems to still spool fine, its prob dirtying up my o2 sensors cause I keep getting a CEL after an hour or so of driving.. just need to make it threw the week. Any input?

I wouldnt, probably better to just park it cause depending on which seal it is, it may be pushing oil through the i/c, and you dont want that getting built up anywhere in the intake tract. And if its effecting your o2's, to much of it may ruin them..next thing you know your replacing your turbo, o2 sensors and who knows what else.

Its a new T70 that my freind put too much teflon tape on feed and it clogged line and blew seal, oil seems to be on hot side when i remove DP.

you mean too much on the return line...blocking the feed line wont blow the seal, it will burn up the bearings and destroy the turbo.

either way, not a good idea to drive with it like that.

im new to this forum and im having trouble finding infomation on a write up on how to turbocharge an sc300 and the specs to how much hp it is capable of handling on stock internals because most of the info i read here is of guys who have allready turbo'd and thats it... im looking for the simplest turbo setup or somthing the is in the 300hp-450ish hp. please help at the moment i dnt own an sc300 yet but im looking for one

your not searching hard enough...the stock lower end is capable of 600+ along with the head depending on mileage, keep in mind that the block and internals are the same as the TT Supra minus the pistons.

300whp can easily be reached with a simple "bolt on" turbo kit and stock compression provided the mileage isnt excessive and maintenance has been kept up to par..anything more than that, be ready to pull the head and install a new HG, and if its an auto SC, better start looking into a w58 or r154 cause at 350hp your already maxing out the auto trans.

use the search function and clubna-t.com for more information. You can also order the XS Power GE na-t kit on clubna-t and have almost everything you will need minus a wideband o2 and some sort of fuel/piggy-back system, fuel pump, and the bit to drill your oil pan.

The installation itself is pretty straight forward, especially with the XS Power kit, but to help clear some of it up:

The install in that thread was being done on a MK4 Supra, but everything should be the same, and I dont think you will run into any of the minor issues that were in that thread such as the bolts not clearing, and what not..but then again, there is no such thing as a plug-n-play turbo, your going to hit a snag here and there, and it will test your patience at times, but well worth it in the end. If you have any questions feel free to pm me anytime.
