    420A Dyno Graphs/loss of power

    This dyno graph is for an example. My 420a turbo hits peak boost, then drops off power much like this graph. What could be causing this issue, and does anyone else with a stock head, have any dyno graphs to post for comparison. Boost peaks at 4750rpm, then falls off a good 30-40hp. On 18psi car...

    420A Syptoms of Bad ECU (PCM)

    The car once again just randomly wouldn't start this morning and about all day. I wasn't getting 12v to the middle pin on the coil, nor was i getting the 8v to the cam sensor. The black/red wire coming from the ASD relay was only read 3v which it should be 12. I used a jumper wire from the...

    420A VSS Causing No Spark

    Alright guys, dropped the car off at my Tuning shop, Brutal Speed and Tuning, in Hickory, NC. I had a lot of wiring fixed under the hood because of an issue, but that issue still exists. When the VSS is plugged up, the car will not get spark whatsoever. However, if I unplug the sensor, the car...

    No spark but fuel

    I know this has been beat numerous times but I need help. My car as stated above has fuel but will not fire at all. The way our cars work is the coil gets a signal from the cam and crank position sensor correct in order for there to be spark. I've replaced the cam sensor to find out it still...

    Fuel Pump Primes No Spark

    Can someone help me out with this. I've been battling it for the past 3 days. First off as the title states, the car has absolutely no spark. When the key is turned to "ON" the fuel pump primes. Also, the WHITE relay clicks on too. However, the black relay does not click on when the switch is...

    I know there are multiple threads on this issue. I've read the link that Paul posted on one of the threads a few years ago.Anyhow, after I installed the valve cover and ran the car a few minutes, oil started leaking underneath the back side of the valve cover. It comes straight underneath...

    Compression Question

    So, on the new motor I decided to do a compression test...I did cylinder 4 first, the number came out at 195. I did cylinder 1 next and it read up to 165, then 150, then 155....So, I did cylinder 4 again, and it read 155...During the break in period, my AFPR went bad, and dumped...

    Car Flooded wont fire

    I know they're are other threads but I'd like a better understanding. My Eclipse has been rebuilt, once again.Just not got about 500 miles in the motor. Ball joint broke while driving, ad done some damage body wise. Fixed it drove it home, to find out the exhaust was broke almost in half above...

    MS2 sharing CLT and IAT sensors

    Forgive me if this is in the wrong thread. I'm on my iPod. Has anyone tried pulling the 2 bias resistors, r2 and r4 I believe, and successfully shared the stock CLT and IAT sensors? I read that you could do this to share them and was wondering if it worked on our ECUs.

    FCD Install ECU "Limp Mode"

    I installed the Symtech Labs FCD earlier today before work. I ran the power wire to the Cigarette Lighter. My mistake was, I ran it to the green/white wire. So long story short, I though I had it connected to a 12v supply that powered on when I started the car. I was wrong. IT would only power...

    Bad Oil Leak

    Once again, I hate to keep bothering you guys. I'm at a point to where I'm fed up. Nothing seems to be going right. I just installed my turbo setup last Thursday. Filled her up with oil, (Pennzoil) and I've since driven it 500 miles. I go to check the oil and it's on the MINIMUM mark on the dip...

    Cam Seal Replacement

    Well guys, I'll be spending part of the day tomorrow putting in a new set of cam seals. 1500 Miles on the motor and the oil pressure light got me. Shut off the car, and put some oil in it that I had in the back. Once I got it home I checked it out, and the back of head was damp with oil on the...

    Fuel Injector Size/MS2

    Sorry to keep popping out threads all the time, but one more thing I'm unsure of are injectors. 420a injectors are high impedance, so I really would like to find high impedance injectors. Would SRT4 injectors work? :hmm: I'm going to be running MS2 as well, so that's something else to throw in...

    okay guys this isn't as bad as it sounds. The build on my car is finished, I've put about 240 miles on it so far. :thumb:The only problem I'm having oil is dripping off the bottom of the oil filter. This isn't a headgasket leak, or anything like that. It's either coming from the Crank Sensor...

    Head Gasket Help

    Alright, so I've ran into a problem. Remember when I said I had the block decked, well I don't think it was, even though it was suppose to be.Here are a couple of pictures, one of the head being surfaced and then the block.Maybe the block wasn't decked because it didn't need it... but...

    Rod weight

    Alright guys. I'm just curious to how much a single 420a Eagle Rod weighs. I've read different things from 550 grams to 535 grams. 550 grams I believe is for the 6 and 7 bolt 4g63's, and the 535 grams is for the 420a? If anyone can confirm or answer this, please do.Thanks.

    How much boost?

    I'm wondering on how much power can be made with a 12:1 fmu, FCD, stock injectors? I just ordered JE Pistons 8.8:1 yesterday, along with eagle rods... I plan on ordering ARP head studs early next week, along with a HG. Will I need bigger injectors to make more power? and if so, what size. I...

    Possible ECU or Grounding Problem?

    I can be driving my car, and randomly it loses power for like half a second, but instantly regains it. I've tried data logging it, but when the "jerk" happens, it shuts off the data logger. The radio and the other electronics don't shut off though, so I don't think the ECU is the problem for...

    420A Bad ECU, or PCM?

    So, after a few weeks the "sudden" loss of power is back. It only happens at the snap of a finger... and it regains power. when it happens the radio, and other electronics aren't effected at all. So, could it be the PCM? I find that if I unplug the batter for a while, and hook it back up the...

    Can Bad Coil Plug Wires Cause a Short?

    Okay, so like I posted in the other thread.... Your coil has a plug on it of course, and then you have a plug that gives the coil voltage... well, those wires didn't have anything on them at all... they were just out in the open leaning on the valve cover. Can that cause those wires to burn and...

    Misfire Problem

    I'm sorry I keep bothering you guys, but I have another issue. I have a problem to where the car loses power for a split second and it jerks when it does. I don't know if this is a misfire or simply losing power. When I hook a scanner up to the car, it doesn't read a code at all. I let a few...

    Transmission Help

    Okay guys, could you tell me what these plastic gears are? the orange one, and blue one? My speedometer isn't working, and I've replaced the speed sensor, and cluster gauge... so, my next guess is one of these plastic gears.

    Speedometer Won't Work Help Please

    Okay, I know all about the speed sensor and everything. I've bought a new sensor, and tested it with a drill and it worked fine. The plastic gear that snaps onto the speed sensor is fine as well. The teeth look clean, and no breaks anywhere on the gear. Now my next question is... could it be...
