They’re uber-sticky, boast long life, and are cheap and easy to find in southern Ontario. These were paired with Hankook’s latest extreme performance summer tire, the RS4 in a 225/45/15 size. In this 15×9” size, they’re incredibly light at just 12.5 lb per corner. These are the Dail-In model, which are flow formed for maximum strength and lightness. Wheels were kindly provided to us by Konig. Needless to say, it’s now the prettiest part of the car.Īt this point, all the car needed was a set of wheels, sticky tires, and a track-spec alignment. That’s when we decided to cut our painting careers short and hand the valve cover over to our friend JP at Stripping Technologies for some powder coating love. As a result, our dirty hands made it look awful after months of wrenching. We threw a can of red rattle-can valve cover paint on our valve cover before it went into the car, but didn’t give it nearly enough time to dry. Hoping to maximize the Ecotec’s potential and, if I’m honest, improve its exhaust note, I picked up an ISR cat-less exhaust, modified it to fit the car’s custom downpipe, and added a Vibrant Performance GESI high-performance catalytic converter. We ended up breaking the car’s factory exhaust during “spirited testing,” right where our custom downpipe met the factory catalytic converter. Naturally, this meant installing sending units in the Ecotec engine’s oil pressure feed hole, and a water temp sensor in the car’s coolant bleed port (the hole that was tapped in part 2). Rather than wiring up the stock Miata’s water temperature and oil pressure gauges, we installed a set of Stewart Warner gauges along with an AEM Wideband gauge in the center console. The Miata’s stock steering wheel is massive, making getting in and out of the bucket seat difficult, so in went Project Feint’s PF MOTO 1 steering wheel along with a Daikei Boss Hub. Next, we focused our attention on the interior. Um so the idea was to try and make a good flowing NA engine before you put. Keep in mind that when using a thicker radiator with an aftermarket sway bar and the Ecotec Miata swap kit’s front sway bar relocation kit, it’s common to run into clearance issues between the factory radiator fan and the front sway bar, so we also purchased a CX Racing duel slim-fan kit. By Rear Axle Divergence - RAD Facebook Okay, Im going to try and do this. This is the biggest, baddest radiator you can stuff in a Miata This is really one of the. Rather than throw another factory radiator into the car, we decided to go with an all aluminum radiator from CX Racing mainly because it was cheap, and proven to work well on turbocharged Miatas.įactory radiators have been proven to work well with this swap, but this solution future-proofs the car in case we ever decide to bump up horsepower later (read: boost). Also, if the intake air temp is cooler, you will also make more power. When we replaced the car’s timing chain and tensioners, we ended up cracking the factory radiator’s coolant hose outlets. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.With our Ecotec Miata up and running, it was time to start prepping for the race track, starting with a new radiator. High Efficiency Multi Louvered Fin – CSF uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. With “B-tubes” you are able to get “dual liquid laminar flow.” 1 large tube within the same space criteria. You get the efficiency of 2 smaller tubes vs. The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes. CSF is able to use thinner and lighter aluminum material (better cooling efficiency) because this design is actually stronger than normal “O” shape tubes that are welded. These “B-tubes” are carefully formed and then brazed over the seam to seal. “B-Tube” technology – Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in a shape of a “B”. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology! CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry leading testing methods to maximize airflow and heat dissipation. Skunk2s all-aluminum, full-size Alpha Series Radiator for the 90-97 Miata is a direct-fit upgrade designed to dramatically increase both cooling efficiency.
