DIY: Hall Effect Crankshaft Sensor

since I’m no longer using the L-Jet system & converted to the 60-2 crank wheel i needed a sensor. i used the threaded shaft style from diyautune at the same time made mount and wired her up with great success!


Fuel Pump Failure

the car had an aftermarket pump upon arrival to the stable. though i was unsure of its age. the 5 years it sat probably didnt help.  went with a tuner favorite the BOSCH 0580254044 @ 300 LPH


harness wiring

This was quite possibly the most tedious and time consuming part of this build. i have a new found respect for those that wire and do it cleanly. this is car is my humble attempt. though i now know moving forward ill go the extra mile to do it correctly.


haltech house

The EMS is a huge part of this project. it needs a safe and accessible place to live. it also needs its own circuitry meaning relays, fuses and distribution points.

this gallery documents my build and placement of the Haltech EMS and components.


plug wire

i grabbed the Moroso 73828 plug wire set. they are a 8.5mm LS-1 based wire, which are unterminated on one side allowing me to custom the length for the e24. also grabbed some v8 loom/separators it took a bit of work to combine and lengthen them but im very pleased.

coils mounted.

finally received the moroso ls1 plug wires i wanted, ill be cutting them soon, but this allowed me to mount the coil brackets and thus the coils. really pleased with my placement decision (originally wanted to go thru FW but decided against it).

i modified a brand new billy boat cat back system.  i went with the BB for the SS build and quality along with the fact its dual pipe with resonators. the mid-pipe to the headers i built myself, its a true dual 2″ pipe with a early stream X-pipe. all mandrel bent construction and welded. i added an o2 bung per pipe just after the headers.

took forever to get right and nearly  lost my thumb,  but im very pleased. god its long.


ITB linkage

someone had asked about connecting the TWM system to the early linkage. here is my solution, using mostly stock bits to keep the adjustments but i made a “Y” for the pin and threaded it to the OE link which was shortened.IMG_4037

parker hose saves the day again.

i cant count how many times i’ve used parker hydraulics fittings for special needs on all my cars. their counter stores are a great resource for barb, metric, and JIC/-AN fittings & hoses.

  • running the e28 535 radiator
  • wanted use the OE sensor from my e24 (which is huge) the standard OE hex plugs wouldnt turn because of clearance
  • solution: Parker 14mm inner hex plug.

AUX. fan interrupt switch

the haltech ems will be controlling my AUX. cooling fan, since i deleted the mechanical clutch fan. here are a few shots of the wiring and switch. the led indicator gave me a fit acting as a diode while the switch was wired to the negative. a little tweaking gave me the following:

  • switch:
    1. Blk wire = ground
    2. grey/red = signal plus jumper to Negative side of led
  • led:
    1. white = jumper mentioned above.
    2. orange = 12v on or acc. wirephoto




Seals-it Firewall Grommets

really stoked to see the haltech harness poke thru these guys. such a nice dress up item!


spal puller fan

since i am no longer using the giant mechanical clutch fan. the spal 30100435 puller fan should be plenty, its only a 10″ its low profile and 802 cfm.

amazon sure knows how to waste shipping space and material.





only a little blood from the new radiator blades.


sexy motor shot

getting close. exhaust and tune remain


Vacuum Block

not bad for an ebay special. the build quality is great. also notice the injectors and fuel line straps installed.

GTR injectors

yes GTR injectors. 3bar  = 570ccc.  thats whats up.



2004 c5 z06 LS1 packs should be suitable for my spark. i got to fab up a 2×3-6 cylinder mount for me.

ls ls1

new fuel system

the old system was flat out garbage. new pump and filter.

velocity stacks

after sending in my measurements these showed up about a week later. would’ve like longer ones but these were the longest i could fit and still use a filter elements. they look so mean, i cant wait to hear it.


ITB : Sidedraft

been installing the throttle bodies over the last few days, i went with a TWM induction systems setup. little disappointed with fit issues needed to be addressed considering price point. a good bit of filing and some additional machining was needed.

after install i recorded data for the stacks based on clearances and have them on order.

below are some of the fit issues:

     contact with tstat housing / hardware clearance.

motor shot

shot of the engine, using this for mapping out the EMS placement. and this is likely the last shot before the sidedraft install.


oil cooler and filter

got a remote mount adapter from the power plant. running inline peterson oil filter with mocal tstat. along with an earls cooler.
