Kurtiss' GT-R

Due to Dean’s unfortunate engine oiling issues, I decided to remove the stock coolant/oil heat exchanger and install the Ford Performance remote oil cooler adapter (P/N M-6881-M50A) and a Setrab series 6 cooler and Hamburger’s 3347 remote oil filter (all with -12 AN fittings). The oil cooler aligns well with the side scoop.

I will add the oil lines after the exhaust system has been built.

Hi Kurtiss,

I know this isn’t the same engine, wondering if you can expand on your decision on not using the stock oil to water cooler for the engine. I am putting an LT4 in an SLC and was planning on using the stock water to oil cooler but just curious about your decision.

Hi Joel,
My decision was based on Ford Performance’s oil flow requirement. In 2015, Ford Performance changed their engine oil line size recommendation on the Coyote engines from a -10 to -12. As you know, a -12 (3/4”) oil line is BIG.

Dean’s engine seized after a dyno run and Ford said it was due to lack of oil flow. I purchased a 2017 Coyote Aluminator crate engine. After I removed the stock oil filter, cooler and adapter, I noticed the oil passages in the adapter assembly were small or restrictive due to poor machining. That’s when I decided to go with a remote oil cooler and filter.

I’m not familiar with the LT4 and the stock oil cooler may work just fine.

Hope this helps,
Kurtiss

Thanks Larry,
I used a multi-purpose cutting bit with the Dremel router attachment (it's what I have). I would use the Dremel #650 1/8" straight router bit if I was going to do it again. I cut 50% into the panel thickness and took it slow.

Kurtiss,

I heard about your GT-R build in Southern California. I live up in N. Cal in Tracy. I am interested in seeing the progress of your GT-R. I am interested in building this kit as well. I am trying to decide between the type 65 Daytona group from factory five vs. the GT-R. I don't know what the cost differences maybe? Let me know if you might be Ok with visitor to see first hand your build?

Hi Jim & Paul,

I live in Palmdale (north of LA). You're both welcome to visit my build and see the car firsthand.

The Type 65 Daytona coupe is a beautiful car. I have been to the Factory Five gatherings at Huntington Beach and the cars are really nice. The build difference is the FF tubular space frames/sheetmetal verses the Superlite aluminum semi-monocoque chassis with billet suspension components. Superlite chassis are very strong, light and stiff. Also, I have heard that the RCR/Superlite fiberglass bodies are superior in mold, fit and finish. The GT-R is a large car (80" wide and 180" overall length). Lots of room to put things and fairly roomy inside.
