upgrade advice

[robertsws]

a quick rundown - new TPS, power steering pump, Spark plugs, belts, oil change, vacuum lines, upgraded BOV, upgraded IC piping, SAFC2, and 3" Exhaust. Cleaned TB, ICV, and intercooler. Replaced valve cover gasket and the 4 o-rings above the spark plug well.

I am putting an upgraded turbo and a lexus AFM on it next. Is there anything I need to do at the same time?

[supramacist]

New radiator cap. New radiator. Walbro fuel pump. Light weight flywheel. Headers. MSD wires. Iridium plugs. Timing belt cover seal. MSD blaster coil. CF hood. Light weight crank pulley. Fuel pressure regulator.
Coil overs or other shocks. Eibach springs. Lexus 550cc injectors.

You're only skimming the surface dude.

Hehehe.


Yea, I would say invest in some of them 550cc injectors, or you may pop your engine a new orifice somewhere.

Good luck!!

trust me supramacist all that and more is on my list. I'm just curious about what i must do at the same time as the turbo and AFM as to not screw anything up and get it running right.

I was thinking of the 550cc injectors but do i have to get a aeromotive fuel pressure regulator at the same time if i do? And will I also need to upgrade to the Walbro at the same time or can I do them separatly in increments due to money constraints? I am also curious about whether or not I will need a boost controller at that time. I am having a air/fuel gauge and a boost gauge or EGT gauge installed as well. What would you recommend? the boost gauge? or the EGT gauge?

[ddmcse]

all 3 gauges
but i guess you could lose the exhaust temp for now
it used to be thought that you needed the fuel line work at the same time but you don't your pressure should be fine for now and add it later
what is the condition of the "stock" engine you have there ?
you might have issues if you start boosting the hell out of stock, with what 100k miles on it ?

i'm just guessing here .

Well if you are getting a Lexus AFM I would suggest you get the 550cc injectors, even without a pressure regulator, It's better than your engine running lean.

[supramacist]

The afm and injector mods kind of go hand in hand.
I would skip those unless maf-pro is on your list as well.

You can't just throw more air into the mix without upping the fuel along with it. Doing all of this with a walbro fuel pump may compensate without a fuel pressure regulator, especially since you're a turbo. As my walbro covers the arse end with that black soot.

my engine has roughly 94.000 miles on it and is in great shape. my compression is between 145 and 153 through the six cylinders. The book only calls for 143. I plan to do a MHG eventually but not at this time since my compression is so good. for now i'm just going to torque down the head to 75 ft lbs. a MHG with ARP studs is deffinatley on the horizon though. maybe six months from now.

The underdrive pulley has been known to be very bad for our engines. Do some more research on it before you put it on

Dont know if i remember right but our crank pulley helps reduce vibrations and the underdrive pulley doesnt.

Cam gears are okay though
