Hey guys, here's the rundown:
Installed a T25 a couple of weeks ago and I'm running at about 7psi
-SAFC 2 (although I did a bullshit tuning job, didn't have a wideband)
-I think my turbo may be leaking a bit of oil... whenever a coupler blows the inside of it has a slick oil on the rim of the coupler
So at idle, my AFC is reading about 60-70 knock. Goes down to about 60~65 when I put it in first and start moving though.
Also, if I stay above 3k rpm for about 10-15 mins, the engine check light will usually come on and knock will go up a good 5-10 counts, sometimes even hitting 80 counts of knock.
Not sure if this is relevant, but when I was running stock a few weeks before I went turbo, my battery died and I had to jumpstart it and never ended up replacing the battery.
The car is a 1992 1.6 with 190,000 miles on it. What do you think the problem is? The leaky turbo? Maybe the lack of an intercooler or the crackjob tuning? Please let me know - I'm really not looking forward to an engine rebuild if necessary. If pictures of the setup will help, let me know.
Thanks, all help is appreciated.
