Decided to drill through some radiator support to increase airflow to radiator


Hard to tell but i ended up opening quite a bit of extra surface area for better highspeed cooling.

Ended up ditching the shroud in order to fit the air filter properly. CSF raditator with 2 12\" SPAL 'medium power' curved fans. One fan sits lower to clear turbo. Other sits higher in more optimized spot

Wires to electric steering rack were wrapped up in thermoshields and secured by steel ties. Steel ties are a perfect solution to keep the thermocloth in place.

The air filter i wanted to run required lots of sheetmetal trimming. Had to fight for every centimeter of space. In the end i grinded abit of the radiator support bar to bring radiator in closer to support bar. Cut off about .5inch of radiator bushing to lower radiator just a bit. Cut alot into passenger headlight area to bring in the cold air and stuff the air filter in.


Also to fit in airfilter i notched the frame abit, and bent ac lines as low to the frame as possible to give max anount of room.

Kit does not require all this extra work but i wanted to run a 6" velocity stack for many reasons. First of all my favorite part about this kit is that the turbo inlet is pointed towards the passenger headlight, an ideal place to route an intake to cold air. I wanted a metal velocity stack so it could resonate the intake sounds and make for one loud turbo from the compressor side. The short distance from compressor to intake inlet makes it easier for the turbo to injest the air and the short intake distance helps protect against heat soak thats something i really wanted aswell. I wanted the intake to be 100% straight, no angles so it wont cut down on efficiency or sound no matter how miniscule. Also wanted to keep the 3.5" turbo inlet piping size and the vibrant 3.5" inlet to 6" bellmouth fit the bill. Also wanted biggest yet most compact airfilter possible and the vibrant "classic" 6" air filter was chosen. It was quite a fight to make it all fit in there but it came out looking good, cant wait to hear this turbo intake set up.

Extrude Honing might be a good option to open up the IWG EFR turbine housing if anyone is interested. I've seen it done before with great results on other motors.

Can you post a reference for this? It is my understanding the objective, in automotive turbos or aircraft jet turbines, to reduce the distance from the blade to the housing and that abradable coatings have been used to achieve that.

Some heat management ive seen from previous builds going on. Also decided to open up some factory holes that might bring in some cooler air into engine bay. Any ideas welcome
