I see no fuel system items mentioned.. ? You can't just throw 560's in there, if you're running the stock ECU/AFM you should grab the lexus AFM housing off the SC400/LS400. It throws some unmetered air in the engine just like your bigger injectors throw some unexpected fuel in the engine. Also, you're going to want to grab a Walbro 255LPH. You're next step after that would probably be an aftermarket Fuel Pressure Regulator & tuning device like SAFC2 or similar.

^^ What he said. My setup is similar to yours 550s / lex combo, and you can not run 550s with a stock afm, stock fuelpump etc. It just doesnt work. It will run extremely rich because you will be adding 25% more fuel without adding the 25% extra air from the bigger afm from the lexus v8. 25% more fuel without more air = pig rich. I dont even know how itll run with big injectors on the stock afm.

WOOP ! For got to add the lexus afm .. But yea i do have that . Should i use the stock afm shell with the lexus afm internals

lexus housing with stock sensor.

All the afm electronics are the same it is the housing itself you need. Make sure to get a legit pump as becareful of the fakes.

what if you run 550 or 560 injectors with lex afm but no walbro?

Fuel pump would run out and it would go lean?

Instead of worrying about getting a fake walboro 255 you could just get the bosch fuelpump.

Witch bosch are you referring to? . If possible can i get a parts #

And btw How to You Hook up the lexus Housing to the STOCK accordion It way bigger .

 

[whitemike]

Brand new walbros are like $85-90 from some places. $109 from driftmotion i believe

I cant find an exact part # for it, someone else might chime in. But i know they make 255 290 and 310 LPH fuelpumps. + Ive heard people saying they'd rather run a Bosch fuel pump over a Walboro because Walboro's dont come in cars and are aftermarket pumps, where as Bosch fuel pumps are pretty much the norm for european cars. Just heard some people say theyd rather have an OEM reliable fuel pump delivering the same amount of fuel as an aftermarket one due to reliability.

Walbro 255 or the Denso pump from the MK4 TT's. So Denso fuel pump for 93-98 Supra Twin Turbo. Denso is OEM on many Asian imports

Man speaks the truth. I just bought a denso.. oem reliability/quality & aftermarket flow rate!

you just have to squeeze it over it, people do it, maybe they heat it right before and use soapy water

or you could have a custom pipe made with the needed bungs on it

I just bought the "new" accordion tube from dm it looks so much better not to mention if yours is original chances are it will soon crack if not already. I also noticed that it is much easier to slide over the lex housing. And is a more durable make. kinda pricey but worth the investment

fuel volume would become a problem.
