Just want to make sure i can do this

[vbryanv]

Let me start by telling you all my upgrades. ic piping, 2.5 intercooler, flowdyne radiator, dragster 3inch exhaust and hks downpipe 3inch.
lexus maf *not install yet
I just recieved the christmas gifts i bought myself.
1. walbo 255 fuel pump
2. rc 550 injectors
3. greddy boost controler

I want to get a few other things, but if I spend another dollar on this car right now, my wife will kill me. lol.

I plan to install everything sometime this week. What i want to know is if i install all this, do you think i will need anything else my SUPRA to run properly. Like i said before i really don't have more money right now. But at the same time iI don't want to damage anything.

thanks

I would wait till i had a wideband o2 sensor on it before i changed my fuel system at all. However there are quiet a few that run 550's/walbro/ and lexus with any issues

of course they are

did he have a FPR anywhere in there? probably gonna need that to.

with the wide band o2 i'm guessing i need a air fuel ratio gauge.

and i don't have a fuel pressure regulator

also with what i'm gonna have in my supra how high would you reccomend boosting and what kind of hp do you think i should be putting out

i wouldnt go over 14 less you get some forged internals.

I would of went with an upgraded ct-26 before i got the injectors and what not.
might as well put that on your list

my upgrade list went turbo / intercooler then standalone fuel management

i have not done the headgasket but im pretty sure it has been done. i've had the car almost 1 year and it has 210k.

i dont want to do the headgasket yet. i know the dangers but like i said im prety sure its been done. the car sound and runs great. any way to check for mhg?

i dont mind blowing the headgasket. then its easier to explain to my wife that i need 2 grand to rebuild.

right now i boost to almost 8psi... what do you think i should boost to and what hp do you think i will be putting out?

Also thinking about sneaking a few extra bucks to get a wideband o2s. and ideas on a good ones to get... i was thinking aem.. \\

tanks

[vbryanv]

i was just confused, wondering with this set up and how it works. what i mean if i hook this up, i will get the reading my AFR, but how will the stock ecu now gets its signal and i,ve got no way to adjust reading
i did not buy it yet its a toss up between afpr and this gauge. i cant afford to buy too much right now...but gonna to squeeze some money to get something else.

any feedback will be appreciated.

[Green7mgte]

i didnt understand any of that.

[vbryanv]

lmao... i didnt understand it while i was writing it.

i'll try to explain a little better.

right now i dont have a AEM UEGO Gauge-Type Wideband.
are their any problems if i use that and i dont have anything to adjust the air fule ratio?

Basically from your list you can install the greddy boost controler. You would be alright installing the fuel pump as well but no real point untill you are able to get a few more items.

A wide band like the AEM UEGO is not necessary but you do need:

Walbro pump
550cc injectors
lexus maf or the LIPP maf
FPR

Basically by installing the lexus MAF with your 550cc injectors it helps to balance the extra fuel with extra air.

You can leave out the MAF but then you would need a way to tune and the ability to see the air/fuel ratio.

You can install the wideband without having anything to adjust the ratio
It is only a sensor so does not effect anything only gives you more information.
