Hey guys,
Just few questions my r33 s1 skyline seems to be running pretty rich to the point its fumming i guess out the back and staining rear bumber just above the tip,
Now im told this is normal due to the mods i have and it not being tuned being ,3" inch xforce exhaust turbo back and Fmic .. hasnt been boosted completly stock,
Besides the shocking fuel economy is it anything to worry about in the long run it isnt backfiring fire or anything to that extreme just notice the fumes really strong can see it coming out the back.
My plan is to get it tuned after upping the boost as i dont want to tune it till ive done stage 1 mods atleast.
Also am i better off replacing the turbo before it dies possibly rebuilding (high flowing) etc or wait till it happens just i say this due to it being a s1 turbo with original ks which is "185,000kms" and i hear these turbos are kinda fragile after such a long use that im scared once i put a bbost controller on and up the boost the turbo wont handle it for long.. Hasnt been boosted at all its whole life just thinking because of its age,l am i just better of replacing it with a bolt or (high flowing) or keeping it till it happens.. It's just a cruiser not a track car but i hear high flowing the stock ones are a cheaper option .
p.s sorry about the spelling and bad sentence structure as im on a smartphone
