lq4--lost in transition!

[blubaldmontess]

OK, so I bought the lq4 and had it delivered to the shop, only to go down and talk to the guys and get confused. The swap is going into my 86 Monte, the engine is out of an 03 Escalade, transmission is out of an 02 I believe, but its got the right torque converter. Thats not what I'm worried about though, its everything else. Heres the situations.

First, its a, and forgive me if I don't use the right terminology, but it uses the gas pedal sensor instead of a cable? I didn't get the pedal, so should I just buy an intake and throttle body or should I buy a pedal? If I go pedal, what else will I need?

I've got the whole wiring harness, the stock one, and the brain box. I've heard everybody say that it should be worked over to make it a plug and play. Who does this and what do they need to know?


Hmmm...what else, fuel, what will I need for the whole system? I've heard get the Monte SS tanks that are from a 4.3, I've heard you can use your regular fuel tank, I've heard it all, I just need some answers before I dive any deeper into this biach....so any help you could give me, advice, things that can help, they'd all be greatly appreciated.

Thanks a million guys

I cant help you with what you will need with the pedal, but if you do switch over to cable, you will need a new computer IIRC. Also, current performance is one place that does the modification. http://www.currentperformance.com/eng_mgt.html

I have used neither of these, but will use current performance since it is right up the road.
Search around though, most places that sell stand alone harnesses will modify yours.

This is what you need I believe and theres no one better then Painless Wiring.

You can get a cable throttle body to replace the drive by wire throttle body.

Jesse at wait 4 me performance is the man for the wiring harness. It will require a little work but if you wire a relay its pretty easy. He can also reprogram to remove any equiptment you wont be running (emmisions, DBW, etc).

Just buy a replacement tank for a FI 4.3 monte. It will come with baffles and be done
with it.

Yep, it's not that difficult to add DBW (drive by wire). Look here for more info: http://www.ls1tech.com/forums/conversions-hybrids/1027957-drive-wire-drive-cable.html

I bought a new fuel tank from O'reilly Auto Parts for a 1987 Monte Carlo with 4.3L TBI. It fits perfect. I also got the pickup/sending unit from the same car. Added in-tank high pressure EFI pump. Here is a link to some pictures of my swap:

also try jesse at wait4meperfomance.com, he can build a complete wiring harness to your needs (elec fans, 02delete ) hes priced for a budget and I believe other members have used him here and had good luck
