Well I recently bought myself a daily driver, it is a 1987 Mazda B2000 with a 2.2L B2200 engine in it. Its a nice little truck and was what I could afford. It is a bit rough but it will get me around while I work on my real car (Supra). Anywho, the truck failed emissions. Here are the readings...

Well to start off my Supra is my DD and must be dependable. I have been stranded 3 times in the last couple months due to not starting, which is very frustrating. The first time was due to a poor battery connection/terminal which I have already repaired. Second time, the battery died after...

Was just wondering if anyone could confirm the size of the banjo bolt that goes onto the top rear of the intake manifold for the brake booster vacuum supply. I am not near my car right now to measure and have not been able to find any information on it through searching. I am trying to add...

Well recently my supra started smoking very bad! I can't figure out why and need some help! The first time I noticed this was right after I did a pull to about 120MPH and came to a stop, when I took off from idle it let out a decent cloud of smoke, I didn't think much of it but since then it...

I'm not engine expert, so this is probably a pretty simple question, but something I have never quite understood. I see a lot of people recommending replacing stock rod studs over xxx horsepower with stronger ARP studs. Now if I am not mistaken, the rod bolts would be under their highest...

I am looking for a plug identical to the OEM plug in every respect besides heat range. The plug needs to be one to two heat ranges colder for my setup. Does anyone know of any place I can find a chart displaying all the different NGK/Denso plugs with a comparison of all their specs? Seems like...

This misfire has been driving me nuts for a while now. About a year and a half ago when I swapped in the 7mgte everything ran and idled great, this is when I had stock platinum plugs etc. I started to notice a very slight miss at idle after I swapped in some AutoLite copper plugs. The miss got...

Happened to stumble on this, thought I would share it. I can't say I know the first thing about how the strain gauge setup works, but I will be doing some reading. Looks really neat and he already has one fully functional on his truck...

Just some questions about the factory knock sensors... First off, how well do they work as far as effectively reducing knock? Supposedly the 7m creates a ton of noise on the knock sensors under completely normal operation, so how does the stock ECU differentiate noise from knock? Does it look...

Well recently I have been in the market for a decent handheld digital oscilloscope which would be wonderful for diagnosing things on my car. This would just be for personal, use, I am not a technician. The only ones I have any real world experience with are the Snap on Vantage and the Snap...

OK well some info on my car 7MGTE MAFTPRO tuning - speed density conversion 550cc injectors Walbro 255lph 2.5" intercooler piping/3" intercooler full 3" exhaust The problem I am having is that sometimes at idle, the a/f ratio will fluctuate from normal to lean and back (will go lean for maybe 5...

Since I live in a VERY dusty climate, I am a little concerned about air filtration. After cleaning my engine bay, I literally find dust EVERYWHERE only a week later, it is crazy how dusty my area is. I have a 7mgte making 375 hp to the wheels and I am currently running an Apexi Dryflow air...

I have been having trouble controlling boost from the beginning, but after getting a quality boost controller and trying everything I still cant get rid of my boost spike. my mods are as follows: 57 trim CT26 2.5" intercooler/piping full 3" exhaust Apexi intake Supporting fuel mods...

Has anyone ever used a helper spring on the stock wastegate? I am running a 57 trim CT26 and my base boost is only about 6 PSI, I am trying to run almost 3 times that much boost (16 PSI) and using a quality boost controller I still have some inconsistency in the boost curve. I would like to...

Well my new boost controller from Turbosmart has an RPM input feature and I am trying to figure out how to hook it up. The directions state "The RPM input can accept a square wave signal between 3.5 and 12V." I did some searching and only thing I found was that IGT may be the signal I am...

OK well I am not an expert on transistors, only know the basics. I recently made the mistake of testing my blue headlight retraction box on a friends car which had faulty wiring, and ended up shorting out the main headlight relay transistor. The collector is shorted to the emitter causing my...

So I have been trying to get more into cooking lately because I am sick of eating out, it is expensive, and most things fast and easy are not very healthy. My biggest issue is my lack of knowledge and skill when it comes to cooking, but that can be fixed in time. The second issue is the amount...

So here is my dilemma.... I have to give up my poopra for paint for a few days, and unfortunately it is my only mode of transportation (I am not old enough to rent a vehicle). I have both work and school every day, but luckily they are within about 10 miles from home. I have a goped...
