• EGT QUESTION by James8485 on 05 Jun, 2008 00:56
• i keep reading about the importance of an EGT gauge at what point when u adjust your boost does it run hotter......
  
  i got one all ready for my K24 swap but have been running about 14PSI and mid way for steepness on the 1.6TD pin with the stock K03
  
  i havnt touched fuel screw or anyhing else. with these small mods would i be running to hot?? i only have alittle black smoke on heavey acceleration.
  
  maybe someone can tell me weather just doing these few things i shouldnt have to worry bout it.
  some insite from the experts would be great!
  
  thanks

• Do you have still have the stock exhauste system?
  
  If so, your probably all ready stepping into melt down land under full load.

• edit: forgot to mention 2 1/2" downpipe, so not completely stock exhaust
  
  My EGT gets up to about 1250 with the following:
  T3 at 10psi
  1/4 turn of the fuel screw
  steepest part of the pin, half turn of the gear under the pin
  stock exhaust
  some smoke, not a thick cloud
  
  If I remember right, before I touched the fuel screw, it was around 900-1000 deg.

• so in reality i should be fine as i havnt touched the fuel screw and only about half way on the pin
  
  turbo running at 16 peak PSI K03 so small turbo, and i do have a 2.5 inch exhaaust from Cat back still stock downpipe though
  
  so i shouldnt be concerned am i right..... other than the 1.6L pin and alittle more boost turbo so small so not to much PSI for motor dont really care about the turbo as i got another one ready tyo go on
  i just worry about the motor as it was just rebuilt 10 000k ago
  worry or not worrry
  
  any comment would be great!

• You are probably fine, but for reference, should get an EGT gauge.

• hey jim what do you think is a safe level to run a K24 on my AAZ it has been rebuilt
  
  i also am intalling an EGT when i do the swap as mani is off but
  what kinda safe religable boost can these motor handle

• I don't know the limit, but I've run 18-20 psi with no problems, although I have head studs, not bolts. But just increasing boost will do nothing for power unless you increase fuel as well. In fact increasing boost by itself will probably slightly decrease power if you don't need it.
