I'm in the process of collecting all the odds and ends to complete my build. I have a Buschur Destroked 2.1 4G64, and I'm ordering a new oil pump for it. My question is: Do I use the 4G64 Oil Pump or the 4G63 Oil Pump? I've looked at detailed pics of each and I can not see a visible difference in the two, however the difference in cost is significant.

I know the 4G64 Pump would work, but does the 4G63 provide more oil pressure?

Any input would be helpful! Thanks in Advanced for the help!

 

Not sure if there is a difference, but I used the EVO front cover assembly.

 

Should be the same, Only variation i have ever seen in 4g oil pumps is between 6 and 7 bolt, one has straight cut gears and one has helical cut gears for noise reduction. both supposedly flow the same, what are you using for balance shaft?

 

Balance Shafts are deleted. So both are the same? I looked up costs for the parts from mitsu. The 4G64 pump is only $78 while the Evo 4G63 is $215.

 

2000+ 4G64 and 4G63 use the same part number- MD366260

 

Thank you!!
