Preparing to do a DPFI to MPFI swap on my '89 1.5L DX using a '93 EX/Si intake.

Can the stock '89 DX fuel pressure regulator be used for the swap. If not, what are my choices for an OEM regulator.

The posts and articles have conflicting information on this subject, thanks for your assistance.

 

u can use the 93 fuel rpess regulartor bc the Dx one u have its between 36-39 psi and the 93 Si its 41-44 psi.... if u going to be runnning ur old D15 engine , it might be a little rich, wich its not going to be harmful... but yes u can just keep it there. as for me i am using my 93 SI press regulator on my 4G intake manifold bc i 'll be wanting that extra fuel when i hit vtec...

 

well ur not gonna be using the dx one from ur car it wont fit anyhow make sure u get the ex fuel rail and wut not... and just use the ex fpr

 

dx fpr wont bolt up
