When last we left off, Project 240SX LSR was under the knife again, in the midst of an entire electrical system and engine management revamp. In this update, we'll continue to follow 5523 Motorsports, Specialty Car, and the rag tag Team MotoIQ as they continue the build with parts from AEM, Fastbrakes, and Earl's Performance Products.

Last Year Project 370Z received some much needed cooling modifications thanks to CSF race radiators. Their single pass/higher capacity radiator and AC condenser combo made for improved water cooling and retained the factory AC performance. But as the year went on into the hotter months during summer, water temperatures started to again fall victim to over heating. The 370Z front end design only has one opening for radiator air flow. So from the get go the top half of the radiator's surface area does not get fresh air. On top of that, I have an external oil cooler taking up the left half of that single opening. So even though the CSF radiator is a large improvement over the OE unit, there is still alot of factors working against it. Top it off with 90 to 100+ degree summer track weather in SoCal, an engine known for high heat production and decently quick pace on track with a significant amount of time spent at wide open throttle, you have a recipe for overwhelming the cooling system. There were a few things we tried before the CSF triple pass unit was implemented though.

If you have been following the progress of Project 350Z as of late we have been testing and running the gamut of your typical bolt on performance parts to see what kind of gains could be expected for a well tuned but lightly modded VQ35DE. With an intake, exhaust, headers, intake manifold, cams and valve springs in place, it was time to get into the ECU and tune for our specific combination of parts.
To perform the final touches on Project 350Z we headed to Church Automotive Testing, a licensed UpRev Tuner to have our car dialed in.

We are reaching the limit of easy bolt on performance gains with Project 350Z. In looking over the offerings from MotorDyne Engineering, the folks that bought us the intake manifold spacer which made such an awesome difference. we noticed that they had a lower intake manifold plenum available for the VQ35DE that would work for both the Rev-Up and original intake cam only variable cam timing engines.

In our last trip to the dyno, we tested AEM's Short Ram intake on our 350Z. We were surprised to find a small but definite power increase over another leading intake that was already on the car. Since AEM makes a long runner Cold Air Intake as well as the Short Ram, we decided to test that as well as an interesting contrast between the two vastly different intake designs.

We have been working on getting more power out of Project 350Z's VQ35DE engine in our latest series of articles. With success coming bit by bit, we decided that we had to give the oiling system a little help. Some 350Z's with highly modified suspension and sticky tires have suffered from engine oiling issues when driven on the track hard. The oil had simply sloshed away from the pickup under hard cornering allowing the oil pump to suck air. Since engine bearings are made of soft metal and depend on a hydrodynamic layer of pressurized oil to prevent damage, any interruption of oil pressure caused damage very quickly.

After removing more than one cylinders' worth of displacement from an SR20DET, the need to improve the volumetric efficiency of our engine through forced induction became absolutely critical. In other words, if we were going to have any chance at breaking land speed records, we'd need a badass turbo system and there was simply no room for scrimpin' here. So, we stocked our turbo system with the best components we could find: A Borg Warner EFR turbo, dual Turbo Smart Hyper Gates, and a stainless steel Full Race Motorsports turbo manifold. Then, we made all the right connections with Earl's Performance Products.

Project G20’s an aerodynamic disaster. It’s blockish shape leads to a car that makes masonry look sleek. As a result of poor aero combined with suspension balance in line with “loose is fast, don’t be a <sissy>”, we needed all the APR aero help we could to tame this bronco.

When we first got Project 350Z as a well used and beat up car, one of the mods the car came with was an Injen Cold Air Intake. Since Injen intakes have a pretty decent rep we simply left in on the car. However, when we installed the intake manifold spacer, we noted that the manifold was full of dirt and that our engine was a little low on compression for the amount of miles that it had.
