this is a very informative post, I like how you laid out what you did etc. greatly helps others. curious tho, did you debate locating the coils to the frame rail and just run short wires direct? ive seen that done with some of the twin setups and looks like it may have worked well in your setup as well.
Thanks. I'm actually in the process of relocating the coils now and running shorter wires.

QUOTE=romandian;1595382494]are you returning the fuel from the rails to the surge tank? that would explain the third connection. and how does the tank transfer work now?[/QUOTE]
I adapted my factory feed to -8an and Feed it to the surge tank. Pumps are Y in and Y out to parallel rails. Return in parallel to the regulator. Bottom port of regulator (return) goes to surge tank. Overflow from surge tank goes back to factory tank.
Fuel transfer works flawlessly thus far. I have had no issues with the fuel system

i was thinking that if the in tank pump goes to surge tank it has no pressure and wont be able to run the siphone tranfer pump.
if it was me, i would run the return from regulator back into the tank (not the surge tank), to prevent any overheating problems. the way i understand your set up, you run the fuel through the rails again and again.

Question, how did you do you oil return? Is it just gravity feed back into the pan or the front cover? Would it be psossbile to drain into the front cover or is it to low? Also how did you order everything? Can you order individual things from CX racing?

Cxracing has many options. you can pick and chose what parts to keep and what to ditch.

I may try it. I'll keep you posted. It can't hurt

I got some questions for you. I'm in the process of installing this kit and I was wondering what size oil return are you running and what oil pan do you have? Also, can I keep my ls1 water pump or do I need a newer style pump, and if so, what year? Last thing, did you end up using your stock o2 sensors, or no? Thanks in advance.

Hope this helps!!! Let me know if you need anything else

Everything is holding up well. Car runs like a champ and the car will be In the roll race event at Fl2k next weekend. I'm buttoning up some things to get it ready. Let's see how the stock parts last through this event!

My 402 build went to **** so I just picked up a L33. Gonna throw my ported 243's on and a smaller turbo friendly cam, and order the kit. Not sure about the GT45 that comes with it, may try a 76 or 78mm ON3 turbski till I dial everything in. Stock trans and rear so can't really push it that far anyway.

Some videos showing low boost test hits. (700hp range) gotta pull the plugs out and re- gap them. other than that she is fine! roads were damp.

Quick questions. So you extended the ac lines going toward the condenser since you moved it correct? On your oil drain did you weld a bung on? You said you used th cold side of the intercooler pipping, What about the hotside? On the radiator you used their whole radiator kit and just built bottom brackets? Thank you

I did not weld a bung. I left the pan on the car and drilled using the grease method (grease on bit to catch metal shavings) then changed oil twice.
I used the entire kit minus turbo, wastegates, vacuum lines and feed/drain. I built my own top and bottom brackets for Intercooler and radiator (c6 ones that come with the kit won’t work). The fans are junk so I switched them with derale fans. I had to get some longer length couplers for the cold side but it all bolted right up for the most part.
