Ok, so I sent my gt28r to ATP to have the turbine housing switched to the new eliminator series, and I asked how much it would be to upgrade to the gt28rs. The guy emails me that it will ge 350.00. I currently only have the ATP STG II setup. He says I can run up to 14 psi and be safe without starting to lean out. Anyone with more knowledge than me have any idea with this, and whether I should do it?
Any input would be great.
Thanks.

As long as you have tuning for the 28RS I would hit it hard.

It will be a nice upgrade..

Well,I won't have the software for another couple of months. I currently have software for the gt28r, which is capable of about 40hp less than the gt28rs. I think it would be fine as long as I don't go over 13-14 psi. I will set my controller at like 12 so that at most it spikes 14.

 

do it while you got it out and at the shop.

 

.....that shop is on jackstands in my garage. And I would really be stretching to afford the extra 400 bucks for the injectors and mika software.

 

what I ment was if the place, I think you said APR, can do an upgrade on your turbo and you can run that upgraded turbo at a low setting on you progame you have now then do the turbo part of it know. then later you can make the fuel system upgrade. thats what I was trying to say.

 

ok. Thanks flyboy. The turbo should be here by Fri/Sat and I will put it back in with the apr snub and the new rs4 drivers side mount. I'll post my thoughts of it on Sunday hopefully.

 

Just recieved word from atp that the turbo will be 'in my hands' by Friday afternoon. I have to work until 10:30p.m. on Fri, so I prob won't get it installed that night, but I only have to work until 3 on sat, so sat night....sweeeeeeeeeet!
