The 90-93 Integra chassis is one that is often overlooked and forgotten. The Rudzinski brothers have had a pet project 1990 Integra RS that they scored for $100 from a high school friend back in 2008. It didn't seem like it would be too much of a burden seeing as Jay wasn't really into Honda's at the time but the brothers wanted a project car to work on together. Anyone who knows DJ or Jay have probably heard about this elusive mythical car they've been working on forever. Almost to the point where some thought this car didn't exist and was just a story. They wrenched on it on and off for a few years and it didn't see the light of day until the summer of 2015.
During its build process It had a K series swap mounted into it long before there were many parts available to make the swap a simple bolt in affair. The first engine to be ran in the car was to be a stock k20z1 longblock mated to a stock k20a2 transmission. It ran and drove around the block under its own power for its' maiden test drive. From there they immediately started to piece together a turbo kit consisting of a Sheepey manifold, Sheepey Intercooler, PTE 6266 and had One6 Motorsports custom fab up the cold pipes, hot pipes and exhaust pieces. After all of the labor and fab work it came straight to me at the dyno.
The first session on the dyno was rough, just like any other new built project car. We had some bugs to work out and some adjustments to make once the car was up and going. Expectations weren't set very high seeing as this was Jay's first race car of any sort. We decided to keep it conservative within reason.
The next step was to hit the track. This was Jay's first time drag racing, ever. He didn't do too bad.
And without hesitation, we went back to the track.
This ended the 2015 season a little earlier than planned but we learned a lot in the process. Plans for the offseason was a K24 Block with 10:1 pistons on Manley Turbo Tuff rods with the CSS process done to it. We ended up doing a 4 piston Pro 156 head and had the manifold port matched. Jay also upgraded the transmission to a PPG dogbox. The plans for the car evolved from fun to serious after just a few visits to the track. He wanted to start laying out the platform for a car will eventually go 8's. The plan for 2016 was to continue on the 62mm turbo and to dial in the chassis and driver with modest power. The brothers put the car back together and by the end of spring we were back on the dyno.
Our goal was to reach a 9.50 on the 62mm. On previous passes when the wastegate/boost solenoid were doing its job we were able to trap 157-158 at 32 psi. On the 9.6 pass we had complications with holding boost at the higher rpm's. We were hitting 32 psi and falling to 27 by redline. We also had a malfunction in our speed sensor at the top end resulting in a shortened rev limiter towards the 146-148 mph range. The car was still moving hard up top and we will make sure none of these issues come up for next season. This pass was done before the track closed for the year. 2017 will be very interesting.
We are back into winter prep mode for the 2017 season. The engine has held up flawless and will probably not need to be touched. The chassis will get some love and we expect to get the car to beat its personal best without any effort. As of now it's still undecided on what changes will be made but current talks are that the car may stay with a more modest combo and be geared towards the IFO FIS class utilizing a 62mm turbo, full exhaust and a passenger seat.
