2500HP RB26 'JUN II' | Worlds Quickest Street Legal R32 GT-R Skyline? [TECH TALK]

Показать описание
Running 80 PSI of boost and in excess of 2500HP Croyden Racing Developments 'JUN II' is one of the quickest GT-R Skylines in the world with a 6.86 1/4 mile pass at 204mph at the time of filming, most impressively with a street-legal chassis and the weight that comes with that!

The heavily modified RB26 powered R32 Skyline runs a Bullet Race Engineering billet block, Turbo 400 automatic transmission mated to a Nissan R32 transfer case to retain AWD, CP Carillo rods and pistons, Nitto Performance Engineering EN40B billet steel stroker kit, Precision XPR 98 turbo at around 80 PSI depending on where power is needed as the cars output and therefore traction is controlled via boost as it heads down the strip.

Electronically the car has a suite of MoTeC gear including their M150 ECU and C187 dash which control and log almost every aspect of the car from injection timing to indicators. With the 300HP odd bump up in power due to the bigger Precision turbo, a Waterman mechanical fuel pump has been fitting to ensure a constant supply of methanol.

Interestingly the team are looking to a future R35 Pro Mod build with where the engine is at including a Jhh Racing head that is good for over 3000HP. As discussed the major obstacle with JUN II from here is the chassis so while there is certainly more to come from the car, the RB26's output is not the bottleneck.

This interview with Con from CRD was filmed at Sydney Jamboree where unfortunately race day was rained off but we're excited to see what the car and bigger turbo setup can do in the future.

Just for the record, we filmed this back at Sydnee Jamboree 2020 back in mid-March which was sadly rained off. The build and records are accurate for that date 🤘 - Taz.

Tough work interviewing someone who’s happy with 1 or 2 word answers. Well done Andre

Those compressor blades look pretty chopped up.

As much as I love rowing through the gears with my 6 speed I completely understand why a automatic would be needed here. Besides the fact you really need to be holding on with both hands at this speed and power.

Building for 3000 bhp thats just mind blowing .
The acceleration must be as Violent as being shot

Wondering about the Haltech controlling the ATTESA? I am looking to use the Nexus 5 for my hillclimb R32 build and when I asked Haltech about the ATTESA they said it could not be done with the ECU.

Amazing. I'm so curious to see what a newer GTR could do with T400 instead of struggling with a DCT.

Dang EN40B! Curious how much more hp it handles than a EN30B crankshaft??

Why does it have a rear exit and side exit exhaust system?
