I recall talking to you today.
You do have to realize that what you are doing is essentially installing a from scratch EFI Standalone system... This is not cheap.. even if you start with a budget system.
Here is a breakdown of why it is so much.
MegaSquirt II Programmable EFI System PCB3.57 - Complete Assembled Unit DIYAutoTune.com
The basic kit is $405
The harness is $85
The optical wheel for your distributor is $45
A basic dummy ignitor / coil setup $150
(This is about as cheap as you can go and avert having to pay for mouting a 36-1 wheel on your crank pulley...)
A complete harness made specifically for your project will take 1.5 days (12hrs) to make.. This includes running everything to custom length, tapping in the necessary sensors, setting and adjusting ignition timing to the new wheel, running relays for the new efi system, fans, fuel, ignition.... etc
12x$82 / hr = $984 ... and as far as performance work, we are cheaper than the majority of shops around us, which charge over $100 / hr
On top of this, you still have to have it tuned from scratch. A full pump gas tune from 0 is $600 on any standalone... this is pretty much a industry average.. call around.
$2269.... is what I come up with going by very average shop prices... and skimping a little on the MSEFI setup.
I gave you a price of about $3000 over the phone because you had mentioned that you were doing a 280ZX turbo... So I figured you would want to probably do a electronic boost controller / FMIC etc... because what good is a standalone running 4 psi ?
