Last time we ended with the SR20 all mounted up inside the E30. Now it’s time to start plumbing it. In this episode, we will be mounting the radiator, intercooler and condenser (yes, you heard that right) as well as making the intercooler and intake piping.
We decided to use our S13 SR20 radiator for this project. After a little investigating, we realized that if we used an E30 radiator, we would have had to cut, reclock and weld the water outlets on the SR to make it work. Using our SR20 radiator means that we can just trim and reuse the hoses we already have with no extra work. We also already have a nice radiator with big fans and a shroud on it, so we save a lot of money by reusing it. The dimensions ended up being perfect.
