The local autocross club had a bunch of SCCA Nationals podium-level drivers in S2000s that were god-level specimens of car control, and other than young morons with them, I’ve never seen a truly bad S2000 driver.I won’t say they’re bad...

Honeywell is a common manufacturer of the high-end oil and coolant pressure sensors that get rebadged by the likes of AEM, they also get used in the medical and industrial sphere. It wouldn't surprise me if they made the MAP sensor as well. See...

Hell yeah, I love donks. Everybody should!

Yeah the Omni TPS I installed on my S2000 was bad out of the box and caused me so much headache, I really wouldn’t advise anyone to buy their stuff.

Due to the loss of my transmission setup in a fire, I'm looking to sell my turbo kit as a change of plans and to fund other things on the car. This is, in my opinion, the best turbo setup for the 4G63 on street duty or circuit duty, bar-none. If...

Radium surge tank has arrived, as well as Bobbys sway bar kit, a new front bumper and the EPS pump. Scheduled a dyno session on June 24th to get the car squared away with a tune. A couple more bits are inbound as well. Really need to nail down...

A couple more pics from the weekend. I believe we’ll have a pretty good album when alls said and done.

Well, GridLife Watkins Glen was a hectic event. Didn’t get the times we needed due to issues with the car. So here’s the recap: Unloaded and got teched. The car never got balanced and aligned prior to the event, so we rolled across the...

What is a bastard 16G? I've heard the term bastard 20G before, which refers to a 20G wheel tucked into a stock housing. If you have a billet wheel 16G from an overseas supplier, expect that the new FP turbo will make a bit more power at higher...

The MAP sensor is on the top of your intake manifold, on the passenger's side.

The Eclipse GS/RS have the 420A engine, which don't have a MAF, they have a pressure and temperature sensor in the intake manifold instead. The 4G63 (GST/GSX) have the MAF.

I just had to post this. We are all gathered today for a family funeral and waiting around for mom to show up so we can travel and my son, and right hand man, Trevor gets a random phone call. Like all of us it is very sus. He answered and to his...

Yeah this doesn't really make sense. The differential is doing what it should, the only unusual symptom is the left wheel being able to turn freely with the other side on the ground. Best guess is the driver's side front axle failed.

When both front wheels are off the ground, when you spin one wheel, does the other spin the opposite direction?

The front diff has the speedo gear. Power is indeed going to the front differential based on that. Check your viscous coupler in the transmission, it may be shot. Failing that, power might not be going to the front axle(s) properly. Are you 100%...

Well, the Hahn Racecraft kit was the proper way to turbocharge a 420A, it’s nice to see the kit fully intact. I can’t see what it has for fuel or engine management, but it’s a great start. With some modernization (Megasquirt) and good fuel setup...

Keep it simple at 10 psi max, the D15 does not have stout rods and will struggle with higher boost levels. You can probably still do a tuned 14B kit one of these under $1,000, but still get great gas mileage if it's tuned right. Just build it and...

The 14B is a great match for a stock bottom end D-series - more responsive, and you probably don't need the added flow of a 16G anyway. Back in the day, the junkyard setup for a D-series was a TD05 flange welded to an HX manifold, 14B turbo, DSM...

There's definitely some good power to be gained without giving much up. GSC S1, Kelford 264 or 268 or Jun 264 all good choices for that power range, but I'd suggest you do springs. A set of BC or Manley springs for stock retainers isn't even...
