Since people here LOVE to talk about upgrading to a ko3s and ko4, i thought you guys would like to actually see the size differences. That, and im sick of stating the differences almost monthly Ko3 - 97-2000 COMPRESSOR WHEEL Inducer: 33.6mm Exducer: 46mm Tip height: 3.7mm TURBINE WHEEL Inducer: 45mm Exducer: 38mm Tip height: 6.8mm Blades: 11 Ko3S - 01+ COMPRESSOR WHEEL Inducer: 38mm Exducer: 51mm Tip height: 4.4mm TURBINE WHEEL Inducer: 45mm Exducer: 38mm Tip height: 6.8mm Blades: 11 Ko4-015 COMPRESSOR WHEEL Inducer: 35mm Exducer: 50mm Tip height: 3.7mm TURBINE WHEEL Inducer: 50mm Exducer: 42mm Tip height: 6.4mm Blades: 11 As you can see and have been told, the ko3s has a larger compressor wheel than both the ko3 and ko4 along with a more effecient design. However, the ko4 has a slightly larger turbine wheel which makes it able to flow the higher power made by chipping better. The best thing to do if you really want to go this route is to buy a ko4 AND used cheap/dead ko3s and swap the compressor wheel and housing to the ko4. This should net you a few more whp and tq Reply cincyTT View Public Profile Send a private message to cincyTT Find all posts by cincyTT Nov 14, 2008 | 01:24 AM Share Share Options #2 EpicWin 1st Gear Joined: Sep 2008 Posts: 121 From: Oregon You're the mod, make it a sticky Here's a cool sheet of what engines a K03s came on (by engine code): http://www.qpeng.com/faqs/engine_faq...they_mean.html Reply EpicWin View Public Profile Send a private message to EpicWin Find all posts by EpicWin Nov 14, 2008 | 01:49 AM Share Share Options #3 Tweaked 3rd Gear Joined: May 2008 Posts: 1,900 From: CT Good info.

For instance, a gt30r can come with a 4" inlet but the inducer is a little more than 2" Reply cincyTT View Public Profile Send a private message to cincyTT Find all posts by cincyTT Nov 14, 2008 | 04:26 PM Share Share Options #7 TeeterTawter 2nd Gear Joined: Mar 2006 Posts: 1,358 From: Sauga "The best thing to do if you really want to go this route is to buy a ko4 AND used cheap/dead ko3s and swap the compressor wheel and housing to the ko4.

Havent gone searching if that was the case or not. Should be cheaper and make slightly better numbers than a new ko4-015 Reply cincyTT View Public Profile Send a private message to cincyTT Find all posts by cincyTT Nov 14, 2008 | 04:58 PM Share Share Options #9 TeeterTawter 2nd Gear Joined: Mar 2006 Posts: 1,358 From: Sauga http://www.gpopshop.com/kkkturbos.html thats there info, i don't think they do Reply TeeterTawter View Public Profile Send a private message to TeeterTawter Find all posts by TeeterTawter Nov 14, 2008 | 04:58 PM Share Share Options #10 A4speed Senior Member Joined: Jan 2006 Posts: 2,646 From: Orem, UT thanks for the good info!
