whats reccommened

[mcammarn]

so this is whats done to my car as performance goes:
3in downpipe
3in test pipe
3in exhaust sytem
2 1/2in i/c pipe

i have a hks evc6 that i want to get installed and a hks turbo timer type 1.
i called a place that can do it (drift office in auburn wa), but they say its not recommended to install with just the mods i have.

so the question is, what do i need?

 

[hvyman]

If your on stock turbo just install it and go to just under fuel cut.

A safc would be a good idea too.

Boost controller and turbo timer arnt hard to install either.

 

[bioskyline]

fuel system upgrades to use the higher boost are gonna be needed. around here on the pacific coast 10psi is pushing fuel cut, so 550's/lex is needed, and possibably a walbro or a USDM mk4 TT pump, with a adjustable FPR.

but what im wondering is why they didn't tell you that you need a fuel system upgrade?


or as hvy just sugested, install it and run at 10 psi?

 

[mcammarn]

im not familiar how to even use the evc or the turbo timer. i mite have my buddy also do the install, as i dont want to do it.haha
i guess you can call me a noob with the aftermarket electronics.
not to sure what a safc is either.lol
and as far as as why they didnt tell me about fuel, not sure.im sure they just want my money.ha
but ill work on getting a lexus afm with injectors.

Everyone starts somewhere and yes electronics can be scary at times especially with a Pricey investment such as a car on the line

SAFC = Super Air Flow Converter

It is a piggy back system to the stock ECU it allows you to fine tune the Air/Fuel ratio for safety purposes so you can make more power

 

[mcammarn]

wont the hks evc6 do that?

I think the HKS evc6 is just a Electronic Boost controller

 

[emericaskater285]

I think the HKS evc6 is just a Electronic Boost controller

Thats all it is.
You better just do the usual mods first, like the 550's, lex afm, fuel pressure reg, and pump.
You can install those two items, as the turbo timer is always a good thing to have, but the boost controller is really not needed with a stock turbo, as they dont last too long under any more psi than about 12.

 

[mcammarn]

just wandering, bt do any lexus afm work?or do i need it from a specific lexus?

Hook up your EVC6 yourself, and the money you save buy and wideband. Hook that up yourself too. Unless you have alot of money then that's a different story.

Has to be from a LS400 from the 4.0L v8 1UZ

The list of AFM part numbers that will work:

22250-50010
22250-50011
22250-50030
22250-50031

They are from 90-94 LS-400 & 90-94 SC-400. If I remember correctly, the late 94's changed to a different AFM half way through and those will not work.

EDIT: Part number source - http://www.jblmk3.com/cars/lexus.php

 

[tErbo b00st]

Feel free to sell that turbo timer and use the money for the AFM. Turbo timers are pointless on water cooled turbos, such as the stock CT26

 

[mcammarn]

and is this the same for the injectors as well?
