JSPEC install question
 

I've searched and read on some threads but i'm confused about one thing. when installing a JSPEC motor, are the fuel rails backwards or are they switched around. I will be doing the swap next weekend (4 days total) and that's the only thing that worries me. Can some one break this down to me in a less confusing manner. Pictures and anyone who's done the aspec to jspec swap will be most helpful. sorry bout the hassle and thanks in advance. I have all the other components to do the swap.

turbo is fine, compression good, blitz BOV was left on the motor and OSgiken twin plate was found when tranny was seperated. kinda got lucky i guess.

Everything is the same except for no EGR and and the Jspec wiring harness.

For an S5 jspec, the fuel lines stay the same way, the fuel feed and return lines are reversed on the S4 aspec to S4 jspec. To see this all you have to do is look at the location of the FPR and the Pulsation Damper. The fuel feed will come from the fuel filter, through the rats nest, into the rail that has the pulsation damper on it. The return line will hook to the rats nest, then into the rail with the FPR on it. The FPR and pulsation damper look pretty much the same except the FPR has a vacuum nipple on it.

thanks for the info. I do have an jspec S5 motor with S5 Aspec Harnesss. i guess i should've mentioned that. so thats pretty much it. i'll be doin the swap next thursday so i'll keep you guys updated. if there are any other thoughts or tips that'll help please leave'm
