I am looking at putting my TA on the bottle and was looking at the NX LS1 EFI wet ket. With my mods, is this the best kit? If not what would be? Also, what accessories should I get? I just purchased the car from the board and am new to the ls1's so I need a little help. I tried searching but couldn't come up with any answers about what kit is good with what cam. I want to run either a 100 or 150-shot and have it purge out through the heat extractors in my mecham hood. Will I also need an inline fuel pump? Here are the mods :

MTI T1 Camshaft (Isky Springs and Titanium Retainers)
Stage I milled/worked Heads
Hooker Supercomp Long Tube Headers (Jet Hot Coated)
Custom Off-Road Y-Pipe (!Cats)
Corsa 3" CatBack w/premium tips.
Yank Super Yank 3500 Torque Converter
Steath Performance Air Intake-top & bottom (ZR1 K&N Panel Filter)
Granatelli Mass Airflow Sensor
210 deg Nippled Hardended Race Pushrods
B&M 24000 GVW Transmission Cooler
MSD Superconductor Wires
NGK55TR-IX Spark Plugs (Iridium)


Thanks
Justin

 

I would stick to either an NX kit or a TNT kit. You'll need different spark plugs. NGK TR6's work nice. You might also want to pull a few (2 or 3) degrees of timing out to save yourself from detonation. I wouldn't spray anything larger than a 100 shot on the stock fuel system. If you wanted to go ahead and upgrade your system a 125 or even a 150 shot would be possible. You might want to pull out a few degrees more timing to run the larger shots, however.

 

I would go with that NX kit. You could run 100-150 shot and maybe go with a step colder plug to be safe. I would go ahead and put the other pump on it just incase you ever you wanted to jet it up or put a 2nd kit on it. If you call NX they will tell you that you can spray 150 on the stock timing but thats all up to you if you want too. But I know you can.
