will stock fue pump in 7mge work with lexus 550cc injectors?

and will stock 7mgte camshafts fit in my 7mge and do anything.

im going to na-t it here soon with ct26

Yes the stock pump will pump fuel through the injectors. No it will not be enough to supply the proper amount of fuel quick after boosting it.

Only the intake cam is different. Yes it will fit.

Thanks man, One more quick question if i put the 550ccs in my 7mge theyll fit the stock fuel rail and the connectors and wont need any ecu changes?

This is kind of meant to everyone on the fourms that helps me out, I know a good amount about cars but not like everything like some older members who actually build their supras but we all at one point had the same knowledge so i appreciate everyone helping me out i do ask alot of questions but i guess thats good lol

stock fuel pump is able to run 550cc properly, it won't last tho

 

[Setsuko37]

okay thanks, but what do you mean it wont last? like will it have a hard time pushing that much and die over time or what? i know in order to turbo i need a bigger fuel pump)

 

[shipkiller]

it's trying to obtain the same amount of fuel pressure in the rail but you're removing that pressure faster because of the larger nozzle IIRC.
Still running below 10:1 with a 57m trim and 550cc, lex maf and stock FP

There are different style injectors out their for different style fuel rails and diameter ports in the head and FR its self. Try Five0 motor sports I have had good luck with them, Boosted Integra and now for my Supra. If you use low impedance injectors you will only have to change the clips over, pretty easy just get some solder a solder gun and some shrink tube. If you use high impedance you will have to use a resistor.

All he needs is top feed import injectors.

Iirc the n/a pump and turbo pumps are different. Yes kragen has 1 part number but toyota has 2. Shouldnt be using a stock pump for over 300 hp. Which will come fast. Esp since a walbro is 100. Shit i got a used mk4 pump with 30k on it for 50 shipped.

NA and Turbo pumps are indeed different. I wouldn't trust an old GE pump to run 550's properly.

 

[Setsuko37]

Well could i run the 550cc's and the ge stock fuel pump for acouple months then upgrade to a bigger fuel pump for when i rly start modifying it more? and how much horsepower gains will 550cc fuel injectors and an gte intake cam bring out?

 

[hvyman]

550 dont add hp. the turbo cam is for the turbo engine.

I wouldnt boost much with that pump. Walbro is 100 new. Not really much at all.
