Description:

Looking for a pain free solution to getting that RB into your S14 or S15? This is the kit. 

Designed with an OEM mindset, this kit is a bolt in solution for the RB engine AND RB25 RWD transmission, without having to guess or manufacture any additional crossmembers or brackets.

Benefits of the kit:

1. Factory Nissan crossmembers and engine mount brackets - This means that the mounting and engine tilt/alignment will be perfect. 
2. Fresh zinc hardware - Grade 10.9 means that the bolts aren’t shit and can take abuse.
3. Powdercoated, vapor honed and new.
4. Leverages the R33 factory positioning with the RWD crossmember - the R33 crossmember platforms are 125mm further forward than the standard S-Chassis KA24/SR20 one, and it’s 9mm lower so factory hood height won’t be a problem.
5. The offset brackets center the Rb25 "big box" shifter in the OEM S-Chassis shifter location.
6. Re-buildable - Exhaust manifolds get hot and melt bushings. Guess what...this kit can be rebuilt. The teal bushing is replaceable and at 95A urethane it’ll withstand the beating and constant engine vibrations (temp range of -40f to 165f of direct heat)
7. Lower than OEM standard R33 GTST Mounts by 17mm which is perfect for the sloping hood of the S-Chassis -- Standard: 73mm, Ours: 56mm
