When we were tasked with building this high revving naturally aspirating 1.6 Lupo GTI bottom end we found that there were no forged rods on the market - so we made our own! We also fitted it with high compression Wiseco pistons, as well as lightening and knife edging the crank.

Check out the rods on our webstore using the link below

Give the guys at Hawk Racing Fuel FC a like and follow. Been great supporting these guys over the years. They always bring unique challenges to repair 👀😂

Another 02M here, this time being fitted with a 3-6 synchro kit as well as the necessary strengthening upgrades - a more budget friendly way to address the 4th gear weaknesses of these boxes without going for a full gear kit replacement. It was also vapour blasted and powder coated so it looks amazing!

This 4Piston K24 bottom end came to us suffering with a cracked sleeve. We machined it for MID sleeves in house, and rebuilt it using JE Ultra pistons so it can take all the abuse Time Attack can throw at it!

A full 1-6 dogbox built for a customer to be used in Hill climb events. This box was fitted with all new bearings throughout, Gripper limited slip diff, billet aluminium shift fork, and billet shift elements. This is the ultimate upgrade for 02M/02Q gearboxes!

4 Piston Honda B16/B18C/K20/K24 625+ Extreme Duty Head-Studs

These studs are made exclusively for 4 Piston by ARP to be the absolute best for your racing engine. There is no other material on the market better suited for cylinder head clamping. 625+ material is substantially stronger than any entry level 8740 head stud material, and substantially stronger than L19. L19 is subject to hydrogen embrittlement and stress corrosion. Even if handled properly during the assembly process, L19 is exposed to condensation inside a running engine. There is nothing you can do to avoid this. Furthermore, 625+ has a yield strength 17% greater than L19 and 30% greater than 8740.

Build your engine with the absolute best from 4 Piston, and turn the boost up! Make sure you select the correct engine in the drop-down menu.

·Each kit includes a complete set of 625+ head studs, nuts, washers, ARP Assembly Lubricant, and installation instructions.
