http://www.toymods.net/forums/showthread.php?t=24482

anywho.. it just made me decide to finally do my 1jz conversion.. this in turn would eliminate the problem hopefully.
WRONG
ive got a new whole motor. new ecu.
sideshow wired it up for me

and yet.. the piece of shit is still running liek a pos my mates charade could beat.

as before it starts idles and drives off boost great. but as soon as u begin to come on boost aaaarrrrrggggghh

anyhelp would be greatly appreciated.. iam going to go pull the codes in a minute.. and ill let u guys know

sideshow recons their could be something wrong with my fuel pump.. so iam going to see if i can grap a fuel pressure gauge of someone to test it..

Sounds to me like a fuel pump problem or fuel filter. When did you last change the the fuel filter??

**pato** · 02-08-2007, 06:41 PM

fuel filter about a year ago. or less,
iam thinking that too.. iam going to crimp the return line to build up pressure and take it for a quick drive.. see if that makes a difference.
how much are walbros these days ??

**xman** · 02-08-2007, 06:58 PM

I think they are about $300ish, been a wile since I replaced mine..

**whatthe?** · 02-08-2007, 07:08 PM

Not even. $150 or so on ebay. Just make sure it's a genuine!

**Endless** · 02-08-2007, 09:32 PM

Did you change the exhaust when u did conversion...

Perhaps collapsed/blocked cat?

Edit - I see you mentioned it on 2nd page in your other thread, did you ever end up checking it?

**pato** · 02-08-2007, 11:09 PM

yea.. i drilled out the cat just to be on the safe side

walbro from a US dealer is only about $106(US dollars)
http://www.fuel-pumps.net/gca315.html - stock pump has a volume rated at 190 lph //$104
http://www.fuel-pumps.net/p526.html - Has walbro 255 //$98

Each of those specific kits were designed to fit the MA70 Supra(I assume by your sig you have the GA70...) I would think the fuel tanks would be the same, so the pump and kit for the MA70 should fit your GA70 with no issues.

I also happen to know that fuel-pumps.net does ship to the "land down unda..." And they are a genuine Walbro dealer

Oh... why is a 255 pump kit cheaper then a oem replacement??? Simple really... Walbro 255 comes with NO warranty, it is considered a "racing part" and as such no warranty.

Endless may have a point. I chased a problem in my 2TG powered TE71 with it running like crap and not wanting to rev, ended up giving up and swapping in a 3T. Same problem, was a loose baffle in the rear muffler moving around and blocking flow.
