Your search for stock fuel pressure returned 20 results.

 

i only got 2 and they didnt say anything about itr

 

search the archives under the ITR forum.

 

thx i n ever knew about the archived files....

 

47-54 psi is what the manual says.
With I/H/E mine is now at around 60.

You really should check the A/F before just setting it at an arbitrary number, but 39 seems low.

 

i think 39 is not what its set at now taht i think about it... i have a a/f gauge, and its always on rich.... even at idle.... ill look at it tonight when i get home....

 

Sorry I can't be of more help.
Is this a JDM or USDM motor?

Stock or with some bolt ons?

 

its a jdm 97 spec with fuel pressure upgrade, i/h/e, clutch flywheel intake manifold gasket, cam gears (0,0), 98 spec header 2.5 inch collector, 2.5 inch test pipe, apexi n1

 

yeha i checked the preessure, it was at 39 psi at idle, i turned it up to 40 psi at idle, and with the vacuum line off (uncontrolled/full throttle) its now set at 50 psi..... still seems a lil low sompared to all you guys....

I forgot to mention that the line either needs to be pinched or taken off, sorry my bad.

You're right in the middle of the 47-54 psi (hose off) numbers.

I only needed to up the fuel pressure once we started playing with the cam gears on the dyno.

 

nice, if u dont mind me asking what kinda number u put down? and what degree are teh cam gears, cause i have fidanza gears and im gonna get my car dyno tuned in the spring....

 

Here's the last of the dyno plots.
DC 4-1 header, aftermarket cat, SMSP 2 1/2" double resonated exhaust with magnaflow small straight through muffler, Mugen intake, cam gears (I think the intake was retarded like 2 degrees ... not quite finished with them), stock ECU, AEM PPR. HTH Ed

 

what year spec itr? jdm, or usdm?

 

97 USDM #151 ... about 78K miles.

I've got a VAFC sitting around here, along with a test pipe and Mugen ECU for when I get some free $$ to get back down to Inline Pro for some work with the VAFC and ECUs.
