From my conversation with Bigaaron, the stock 7M-GE fuel pump is too weak for the 1JZ. That's why he's changing it with a Walbro 255 while the car is still there.

I am having absolutely no fuel related problems with my stock 7m-ge pump.

What Kyle said is likely as well. It's not to hard to pull off the coil packs and check them.

ok well i've just gotten from a friend of mine and they were still in good shape... and if so...could you explain the conversation more about the fuel pump being too weak... ok ok... maybe everyone is misunderstanding my problem... hmmm... i mean the car runs great its just towards higher rpms where fuel pressure goes down from WOT it seems that i goes down too much to where it feels like it cuts off for a split second but i dont drop out of my powerband. then after that split second instead of droping power it increases even more... but i can look over my coil packs again, but i really doubt that it'll be it because like i said i just got 'em from a friend who took really good care of them... so i hope this would kinda clear up any confusion.. i mean its not really bad thing it pulls really great like i said and all its just why does it do that around higher rpms... thanks guys again in advance....

Did you mention any pops?

Mine hesitated up high because the coilpacks were cracked on the boots.

Get a wideband or go for a run on the dyno and find out what your AFRs are at higher RPMs. That will tell you if it is a fuel related issue.
