I've been waiting for my fuel pump to show up from lightningmotorsport for a while now, but I'm assuming they ran into some trouble with the hurricane as they aren't answering phone calls...

Anyways, I've got a stock greddy kit, with an MSD timing box, vortech fmu (12:1 disk) set at 7psi.
I have 1.8l tan top injectors waiting to go in, as well as a vortech recal kit...

I was planning on waiting until the fuel pump comes to throw the pump, injectors, and an 8:1 disc in... but i'm not sure when the pump will be here.

So... if i were to put just the tan tops in, with the stock 1.6 fuel pump, what disk would you guys recommend running? Would it be best to just wait for the pump?

Also, WITH the pump, would 8:1 be too rich for 7psi? I'm waiting on a tonyDP so i can install my wideband, so I need to play it safe until then...

 

Yes it is overkill I was running 8psi on my tan tops with factory fuel pump and vortech(stock disk)

 

I know the 12:1 with a stock pump and tantops is too rich... what disk would be best?

I guess i can pull the narrowband o2 sensor and put the aem wbo2 in, as long as i send the white (analog) into the stock o2 wire, right? Does it need some sort of simulator?

 

rich is cool dude, just do it, make sure to have a vta bov and a straigh pipe, does mad dope ricers pops between shifts, shoots flames and everything lol







im only kidding, ull be fine with the 12:1 , just ull take a small hit on ur gas milage

 

It's been so long since I had a stock DP, I don't remember where the o2 sensor is mounted... but you don't want to put a wideband sensor any closer than two feet or so from the turbo. It will have a short life.
