Who on here is running a top swap with a smaller pulley with no trouble.
getting car tuned in a few weeks and would like to try a 3.4 or 3.5. Is it possible without an IC? Vs cam . Headers. Ported blower. 180 therm
 


Every car will react different, But my buddy is running a genV top swap with a 3.3 pulley. Tog headers, 180 stat, ls1 tb, and cai are only mods 0kr

 


i was running a 3.4 on a top swap and i couldnt make it knock and i didnt run out of injector either.

i was also cammed.
 


IDC's are hard to go off of too. There have been guys to show 120% IDC on there logs on a DSM or a 3000GT/Stealth. Obviously you can't go over 100% so most people try to keep it around 80-85%
 
unless i see knock and the car starting to run lean up top, then i would never swap injectors. this is why EVERYONE needs to run a wideband on any car they want to make power with.

Definitely agree with the wideband.

Had I been running one earlier in my ownership I'd likely still have my modded TSi Talon.

Running lean at 6000 rpm and 125 mph makes for bad things to happen to pistons and rings.
