Will upgrading the turbo cause tuning problems?
Hey guys i am new to this forum, ive read down through as much as i could and tryed to search for what i am looking for, but it seems nothing fits my question.
A little history, ive owned my 87 turbo supra for about 3 years, she was great, i decied to take her apart to do a rebuild. somewhere along the road i ended up getting a second 7m-GTE so one gets rebuild while one is in car for my summer driver. so my questions are: 1. if i upgrade the turbo to say a .60 trim from driftmotion, will i have tuning problems? I live in a fairly small place with very little tuning help. 2. if i stay with the ct26, but upgraded to the .57 trim, will this cause me tuning problems? 3. What kind of systems could i get that would help with this? ive read a fair amount about a few but i am still really unsure. If this has been posted point me that way. Manny |

The stock fuel system and ECU will handle the 57 trim in MOST cases without issue. You may run into fuel cut at higher RPM but I don't think you should see much of that as long as you're not increasing the boost pressure beyond the stock level.
