so what's the fuel pressure to be set at with fuel return?

 

Thanks for the comments guys.

I'm rumming the 6-speed w/ a 4.11 welded diff to be exact. Should be a lot of fun. I'm currently trying to get my driveshaft worked out but, once thats done I'll have some driving vids posted.

I'm running my fuel pressure with the stock settings of 52psi w/o the vacume line attached.

 

so you think a walbro 255 pump should be good enough? or my factory 195 pump?

 

I know Z1 motorsports is using all the stock fuel system for their 320whp car...

 

ohh, i should if specified. I am swapping in a VQ35DE into my 240sx and want to utilize the stock fuel return system. Thats why I asked what the fuel pressure would be set at in fuel return mode VS returnless fuel setup. And if the factor ~195LPH would be enough or should I upgrade to a 255LPH ?

 

Z1 Performance

if stock pump is 195 lph that's bigger than a stock Z, so should be more than fine

stock fuel pressure on a Z is around 53.5 IIRC

 

sorry! my bad!

 

I'm using a Walbro 255 which is good for gobs of power. Overkill if you ask me. You should be fine with what you have if your just going to run a stock engine.

 

I have a short low quality vid. More to come later.

This is with a Borla 3'' XR-1 round, and a 4.11 rear end. I start in 2nd gear only going 1/2 throttle!

^^^ prob with the vid link again...

You might consider photobucket, then linking here.

 

Fixed the problem. Sorry! I really need to check after....

 

You got some pretty cool vids on youtube.... need more pics!!!!!!!

 

F-ing nice!!!! rpms climb REALLY fast on throttle... that thing will be a beast on the track!

* note to self = unsubscribe to thread - or get a dedicated track car! *

 

Thanks guys.

I'm curently changing out my rear end out for a 3.54 because the 4.11 were waaaaay to short and I wasnt able to put the power down when exiting corners. It was pretty rediculous I was shifting gears all the time and I could accelerate in 6th fairly quickly lol.

Here are some finishing pics.

 

Looks sick!!!

 

wow... i want that.

 

Nice! Thanks for sharing your project here. Very nice work, clean.. Sexy.

 

bring it back...



<-----looking for something to replace my 240sx void...

 

I would definitely go with a different swap for that car! In fact, I would never swap in a vq into another car, so much money for not much of a return

 

that car is so much WIN!
