I was not the first to put V6 brakes on the 4 Cyl gen 1. I did toy with the idea way back when I got my first Raider in 1994.
What I did do is put together a web page with some info on the various rotor sizes and caliper types. Also noting that the V6 brake booster makes a big difference.
Since that Raider was an 88 I already had OK brakes I never did the swap to the larger V6 rotor. At the time I was building my first Turbo raider I had my hands full with the engine swap and had two weeks to get from the east coast to Santa Barbara and complete the vehicle.
Scary? Scary is driving 3500 miles on a new motor and conversion to get to a new job, hoping you did everything right. I had enough time to put about 300 miles on the new engine before I left and did a quick oil change that day I left. Final pieces were put in place less than 30 minutes before hitting the road.
Once in Santa Barbara it was apartment life so my projects were limited.
That Raider got hit about five years ago by an F150 (ouch).
The new raider is an 87 and had the worst brakes. An upgrade for that model year is basic self-defense, especially once you put on taller tires. By the time I got this Raider I had a place with a small garage.
I did my first turbo swap in 1990. I was not the first on that one. I may have been the first to put one in a Plymouth Arrow. A mechanic for the Mitsubishi race team put a turbo 2.6 into a 4 door colt. The Arrow weighed 2400 lbs and ran 15 psi boost. I did do a brake swap on the vehicle. I put vented four wheel disks from a Starion onto it. The swap included making caliper brackets for the front and strut tubes and control arms from a Sapporo. 115 mph to 0 stops without fade.
