I was cleaning my injectors after the car sitting so long, just using one of those cheap fleabay kits. It's basically a plastic nozzle to connect to a carb cleaner can, and an injector pigtail with alligator clamps to hook to the battery. Worked great on the drivers side. I energized the...

I took my one car out for the first time in a shamefully long time. It drove great for most of the map but at hot idle, it was just absolutely rich (0.68 lambda) to the point it would often stall. It had been sitting with E85 in it, fuel stabilizer, and I had thrown some injector/fuel system...

I'm planning on making my own offset bushings for the ATS Brembo calipers. The main thread is pretty cluttered with all kinds of other information so I thought I would split off discussion here. For the S&S kit- are those still using the Brembo 14mm bolts versus the Cobra 12mm? Does anyone...

What battery is everyone running? Less interested in brand and more in the group/rating/CCA of it. Mine has always seemed kind of weak to start my car, but with the return fuel pump it seems to be pushing it even further and I think I'll need to upgrade. For the record it's got a trunk...

Friend got a new toy. It's a nice car, but as you can see, the airbrush job on the front is tackier than a tiger skin rug. The question is- what to do with it? Leave it for the New Balance crowd at car shows? Sand it off? Paint over it? Wrap or dip it? Sell it? It's only on the front bumper and...

...ads. Get Ready for In-Car Ads Cliff's: Ford has a patent on a system to see billboards and bring up in-car ads on your infotainment system. Science fiction becomes reality every day. There is no escape. Consume. This could be extraordinarily profitable for them. After all everyone else...

With the pandemic, it seems like none of the trailer dealers have anything capable of transporting cars in stock. And for a new one they're quoting a 4 month lead time, if they're taking orders at all. Needless to say, prices are way up as well. In this kind of bind, does anyone have any...

I'm no SVTP baller, and my current landlord has informed me he's putting the property up for sale. I'm open to put in an offer, but he's already received one before even putting it in on the market. The number he gave me I thought was obscenely high. But I checked at some estimates online, and...

Bought a used 302 to throw in the fox. Engine turns freely. I changed the oil and put a new filter on. Went to prime it by turning the oil pump shaft with an extension and drill, and it just won't pick up or push oil. I'm turning it the correct direction (verified in the Chilton's manual)...

For some reason when I get on it, my boost gauge doesn't read- it stays at 0. I even installed a cheap HF boost gauge in parallel, T'ed off the same line, and the car is in fact making the boost it should. If I bench test both the gauges by supplying regulated shop air to the vacuum lines, the...

Has anyone installed and run the new MegaSquirt plug and play ECU? Any thoughts or reviews on your experience? I'm looking to finally jump into the deep end and go standalone, realizing that it's probably much easier (and cheaper) to get a new ECU than to build/integrate modules to work with...

With turning up the car I've been looking to upgrade the ignition system to handle 30psi. I figured I'd share some of my research and thoughts on pros/cons of different coils that could be a more cost effective solution than a lot of the aftermarket ones that don't always have the best...

I'm running the 210lb/hr Bosch CNG injectors, the medium length EV1 ones. I checked all the drawings and ordered the 12mm length spacers. Now with the spacers installed, the injectors measure from flat face to flat face the same length as the old 60lb/hr EV6 injectors. But when I go to bolt up...

For anyone running the Bosch 160lb/hr or 210lb/hr injectors, did you have to change out the O-rings on them, and if so, which ones did you use? I've got a set and I was comparing them to the rail and some old injectors. On my cheap calipers the O-rings are the same dimensions on the old...

When you switch a return fuel system, as I have, you know that heat is the enemy. Get your return fuel too hot and your pump can cavitate, losing pressure and damaging components. This gets worse and worse the more power you make and the bigger pump you use. You're still only using a few hp at...

Got the car out for the first time this year after switching to a return fuel system over the winter. It cruises around great, but when you step on it, as soon as the turbos start to spool it flat out falls on its face. I'm not talking breaks up or goes lean, it completely misses until you let...

Does anyone know what the output frequency of the FPDM to drive the pumps is? From my understanding the FPDM takes a 150Hz (0-5V?) 5-50% duty cycle PWM signal from the PCM and turns it into a 10-100% 0-12V signal to drive the fuel pumps. I haven't been able to find an answer anywhere and don't...

Anyone know where I could get or make a custom lamp for the gauge cluster? I want to replace one of the existing ones (likely traction control) with my own "Eco Mode" lamp for when it's on the 15psi/low boost setting. I could always get it from another gauge cluster and graft it into my own, but...

Issue: Car should be making 15psi but I'm not seeing it. Configuration: Two stage compound. First stage is twin 66mm turbos wastegated at 5psi, referenced to stage 1 boost output. Second stage is a ported Eaton M112, stock pulley size. Boost gauge is a stock gauge with the Hilton high boost...

What's everyone running for fuel rails, and how do they like them? Looking at aftermarket fuel rails I see the only real options for the 03-04s are the Aeromotive and Division X pieces. The Division X ones do appear to have a scallop in the passenger side ones to clear the plenum and studs, but...

I recently got my first notification from SCT following the EPA settlement. It reads- Dear Advantage licensees, In accordance with our Consent Decree with the EPA, effective January 2, 2019, we will implement tiered access for dealers using our Advantage Tuning Software. Prior to this, you...

I thought I'd post some useful information on my recent upgrades when my original Bosch IC pump decided it didn't feel like working anymore. Overview: I've got three sections on what I upgraded. You can mix and match if you'd like. The first and most important is the pump. The old Bosch pump...

I've narrowed my sporadic idle stalling issue down to either spontaneous over fueling, or the IAC periodically dropping out. It will be idling perfectly steady, then suddenly drop to <400RPM or die. Opening the throttle (i.e. adding air) a little will save it. Reported IACDC is steady, and the...

The problem: On a cold start, after awhile the engine will surge really bad and die. Background: Neutral idle air table is tuned. Pretty much the stock 03 function. Just about dead on at hot idle. Idles great at hot idle. Throttle bypass air is tuned. Where I've been doing most of the tuning...

After it's long winter slumber it seems like my stock IC pump doesn't want to wake up. Just like anything else, what's the fun in replacing something with a stock component when you can upgrade? Looking at some of the more attainable upgrades, one of the first that comes to mind is the 13-14...
