Endurance R32 GTS-T build

Recommended Posts

Hello all,

First a quick intro about myself i'm currently a junior in university studying engineering across the pond in America, and my goal is to have the first W2W circuit r32 in America. This is a pretty bold clame but I'm determined to get it done as I believe I have enough prior motorsport knowledge where I don't believe its a shot in the dark. Now, there are lots of time attack cars running around, but that's not my jazz. I have raced in an enduro series in the states for a little bit but wanted to build my own car. The car is a '91 hcr32 that I got back in 2017 and it has been an open track day car since. Just recently have I started to tear it down and start some development on the chassis and engine. The car came to the port pretty much standard.  


It then then got light modifications to serve as a weekend/dual purpose car like hicas delete, cusco coilovers, solid rear subframe bushings, koyo rad, koyo oil cooler, 25neo turbo, fmic and some other misc stuff.  

Fast forward to 2019 when I was off at school on the other side of the country the car came with and got some more work such as a lot of new bushings, front and rear camber arms, tension arms. The rb20det got some love with a Garrett 2860rs turbo, all supporting modifications and a haltech platinum pro after the nistune board and kinugawa turbo took a poop. I also did some development with some catch can set ups and found a 2 can set up that worked good for me.



The car had since done countless open days at various tracks to keep me busy in between school, work, and racing this e46 which was owned by a friend at school and his dad.





Back to the r32. The plan for the car is to build the car roughly to make this coming season and do a lot of testing to gather any info that will help me for 2 years down the road when the car will get refreshed and another engine built that is more suitable for race use as the motor in it now is the refreshed motor it came with. The series I want the car to eventually race in is called WRL, which is an endurance series based in the states. To start where there car is at currently I have just finished removing the engine and stripping the car to prep for a cage which is being built by a well known race shop here in Colorado. The car left to the cage builder in a fairly empty state.



While the car is currently at the shop still I have been busy refreshing the ol 20det with a refreshed head, all new gaskets and pumps, and a checked over bottom end. I was also keen on trying a cheapo top intake plenum on the "mule" engine for some tests.




Most of the safety equipment is sitting in the garage ready such as a seat (OMP HTE-r), sabelt 6pt belts, window and drivers nets, and some other misc stuff. I have also been busy with sorting out the harness that will run to the rear of the car to control the lights, as I took the stock harness and stripped the hicas, amp, rear wiper, and other misc junk out of it so its very skinny and will fit next to the battery cable to the rear passenger side of the car. This is pretty much up to date, so feel free to ask any questions as I will try to update this forum as much as possible as the car will be back in the garage early next week and will be getting some paint on the interior.

Great to see!

What are the main rules for the WRL series? Do you need to keep capacity at 2l for instance?

So the WRL series has 4 classes ranging from pretty much prepped e36-e46 spec race cars all the way to Porsche gt4 club sports. The classing is done on a PWR (power to weight ratio) basis with point modifiers for things like a sequential box or air jacks etc etc. The plan as of right now is to try to keep the 20det as I was pretty unsuccessful on finding documentation anywhere online about rb's built for endurance and I know the 20 can take a hell of a beating given it has the right support obviously. Once the car is done I can get it on the scales and see where I'm going to have to fall power wise, but from a rough guess Im thinking it will be sweet around 300-350 whp (220kw - 260 kw). Unfortunately for me I think im going to have to do most of the R and D on this myself as ive asked around as much as I could over here in the states, unfortunately everyone here with skylines is either obsessed with just outright power or time attack cars and not any w2w or endurance support. That's why I'm talking to the great knowledge base on here.

This is interesting.
Keep the oil cool & good catch can setup you will be fine. Spend the time getting the car handling & be reliable, You'll probably find yourself going better than guys with big horsepower.
Depending on the rules is there flexabilty for basic aero?

Yes there is some room for aero, it does add some points to the modifier, but I think it’s really worth it in my experience. I’m planning on doing a simple rear wing and front splitter as far as big aero goes.
