I'm in the middle of doing this stuff on my car, so I have a bunch to say and it's not coming out in a coherent order, sorry.
Haltech recommends the Elite 2000 or 2500. The 750 will not do idle control among other things and must run in piggyback with the factory ECU.
(I'd probably recommend the 750 on 4 cylinders in piggyback. I went for the 2000 for my turbo 6 project and kinda want the 2500 now and a PMU)
Also, Haltech products are NOT cheaper when you buy them direct from Haltech.
Some of their products have been discontinued: Elite 550, Elite 950, Elite 1000, Elite 2000, Elite REM, Elite VMS, Elite VMS-T.
Shop around, old stock is cheaper. Golby, EFI Solutions etc.
- How much of this will you be doing yourself? Wiring etc?
- Do you want to run the factory ignition and DFI module?
- Do you have a power target long term?
Factory 8 inch diffs can't handle much more than 450hp after being built.
Stock conrods break at less then 300hp too don't they?
One way valve for the brake booster.
Internal PCV needs to be blocked.
Fuel injectors and fuel type?
Can bus - wideband, flex fuel?
A 600 x 300 x 50 intercooler will be hard up against the AC line and impact bar. If you're keeping the AC, you'll probably want a smaller FMIC. Plus that's a 3" in/out on the cooler? And 2.25" on the turbo? That's a bunch of volume that turbo has to fill before it finds the throttle body.
The 4L60E requires an electronic transmission controller, the stock ecu does this in factory form.
You can do this with a Haltech but you need plenty of outputs.
Don't forget you need ecu outputs for the Speedo, oil light etc. Boost control solenoids require ecu outputs.
You can get IO expander boxes for the Haltech ecosystem.
And you can get stand alone trans controllers.
And you can get non electronic transmissions.
Ring Haltech!!! Have a chat with them about what you're options are and what the limitations will be.
Pick a tuner, speak to them in the planning and development stage. Ask them what sensors they would like to see added or replaced on the car to make the tune safer and more accurate.
