    October 24, 2018: Built the car back up, ran her on the dyno with 10psi and hit 230 hp. Decided to get an ignition setup first before hitting 26 psi. We'll see what happens on the dyno in about two months. #NeverGiveUP

    420a engine INTERNAL diagrams?

    I'm sure by "internal diagram" you are referring to a service manual. So what I would suggest is view the sticky posts for links to the factory service manual. You will be able to find all of the information you need regarding tolerances and specifications during your tear down and rebuild.On...

    98 GS ECU Internal Damage Identification Help Needed

    They stated that the car didn't start when they put a battery in after the car arrived. I wasn't there so I don't know what happened. I do know they left the car out in the open weather for a few days with no hood on. I'm assuming that they shorted something related to trying to start the car...

    If I say OBX will you take me seriously?

    I started this thread a long time ago. Ultimately, I ended up using another brand however, if anyone recorded data from their dyno run with their OBX cam'd vehicle, would you mind posting the results? I think that would seal this thread right up for those just getting into the scene.

    98 GS ECU Internal Damage Identification Help Needed

    Just the person I was hoping would chime in. I do plan to carefully strip out the potting. I'm glad a soft polyurethane potting compound was used. It makes the board much more serviceable, and helps in situations like this for us to see down to the board as well for potential problems.In...

    Back story: Purchased a 98 5spd Eclipse a month back to use as a daily driver. Everything worked flawlessly. Front end was misaligned due to a previous collision. A business acquaintance offered to help me get the frame pulled. Took off all front panels, removed battery but left ECU under the...

    PORTFUELER help!

    You need to pick up the split second AIC1-G4H with data acquisition then. It's the company that makes portfueler for HAHN. You can upload your current maps with the R4 program and never skip a beat, but with data acquisition you can overlap AFR and up to 3 other 0-5v Sources of data to really...

    NOV 23, 2012: Car is back in my shop again. Rather than installing the MS, the Splict Second AIC1-G4H with data acquisition is being installed. This is essentially what they sell to HAHN as their "portfueler" but with an additional 4 aux ports for data acquisition. My AEM X-wifi will be feeding...

    Fun with tubular manifolds

    sorry, I don't get on here much with my new job. For anyone interested, I can't remember the name of the exhaust, but when I go to tune the car for the guy who got it from me, I'll take a look. It's from 2005 or earlier. Not sure if the company is still around. I'm sure comparable can be found...

    Rear brake caliper carrier measurement available?

    Don't know if I'm just tired or what, but I can't seem to find my notes on the measurement of the center to center distance of the rear caliper carrier. Do any of you have this info on hand? See pic below.[img=http://s15.postimage.org/9g25n8syv/rear_face.jpg]

    I've been cheating on my Eclipse

    I bought the car the way it looks. It's in mint condition all around so I couldn't complain about a bodykit. The paint is a tri coat, so I can't exactly slap on some stock replacment items without a bit of money. So I'm just gonna enjoy it like this until I get the engine built.It's and N/A...

    Rough idle, bogging, hesitation narrowed down to fuel issue

    My problem in this thread was a leaking seal at the fuel pump. I was able to find it by using a fuel pressure tester. When my car was idling poorly, I could see fuel pressure drop very low. Start there.2nd car I drove after this ended up having a rusted fuel tank. The rust clogged not only...

    Portfueler stage V and the pending dyno visit

    although I'm still doing the work to the car, I don't own it anymore. I traded it for an RX8. I just made a deal with the new owner to continue on with my goals doing free labor and tuning, if he bought the parts.He doesn't know much about cars and wants it to remain factory operational...

    Portfueler stage V and the pending dyno visit

    Dec 2, 2011: After replacement transmission was installed, the 2nd HAHN porfueler control box failed. The internal map began reading incorrectly and fuel maps were useless. Will be installing MS in a piggy back fashion now, but may unfortunately have to wait until January/February from time...

    Direct port nitrous injection, considering a progressive controller

    Here is a pic of my set up.. installing this week. Looking to see if anyone has used a progressive controller here instead of just the momentary switch. Starting with the lowest jets at 75hp. I feel like that might produce quite a jolt. So chime in and let me know your opinion.

    A/C control relocation

    as the wideband begins to fail, it lingers one way or the other. When it doesn't agree with the other two gauges, I am able to pull it, inspect it, and prepare for replacment. logging, or any type of tuning activity can be ruined by a failing wideband. I like to be extra careful.Back on...

    A/C control relocation

    the two narrow bands help me monitor the life of the OEM sensors. Plus, the narrow bands in tandem can also aid conversely in helping me determine the health of the wideband. When using leaded fuels, widebands can die very quickly, it seems more quickly than the OEM units. (ask the wisemen for...

    No matter how much power I wanted to create from my car, I always knew I wanted to keep A/C for summer time. I wanted to use the center of my console for gauges and other aftermarket controls, so the components had to go. Here is what I came up with, and yes its operational.<a...

    420a heating up

    If you are using the wrong size slim fan for your radiator AND you are not running the radiator from the AUTOmatic eclipse, it is possible even with all new coolant system components to still overheat. Not all slim fans are equal, they push/pull different amounts of air given blade design and...

    LSD still has warranty coverage, but found the chewed up gear inside the transmission so I'm not going to mess with the Quaife, just pop it in the next trans.And about buying on craigslist, it depends on where you are. A person selling a trans for $70 from California doesn't do me much good...

    Crower stage 2 turbo grind cams

    I forgot to end this thread. I found out that the Centerforce clutch I had installed did not self center like the OEM clutch.
