    420A Radiator Options

    I use an aluminum rad bought from ebay, for a 4g63. All i did was re-plumb the hoses. It's not as difficult as you'd think. In junction with 12" cooling fans by Imperial from Advance Auto.

    bolt-on upgrades

    Bolt-ons do not add HP......... They merely free up restrictions put into place by the manufacturer...... So sure it feels like it "adds", but in reality you're increasing engine output by making it breath better. On another note, this boost game aint cheap........ Rule #1 NEVER modify your...

    420A Any intake manifold swaps fit the 420a?

    l This is the manifold i built using Treadstone Performance's DIY kit....... Also if youre looking for a quality intake mani, look up Mike Frye a.k.a. All Motor Mike. I dont believe he's on this forum. He's originally a Neon guy. Facebook is where you can find him for sure.

    420A Any intake manifold swaps fit the 420a?

    But it takes months and poor communication to receive one........ a couple people who I've spoke with that have ordered from them tell me it's like trying to buy stuff from Carbonetics....... months and months of empty promises.

    420A Any intake manifold swaps fit the 420a?

    You're gonna have to post some pics of this manifold. I personally have never heard of one before. I fabricated my own mani using a tubular cast SS universal DIY kit from Treadstone performance.

    420A Anyone running a BEGI FMU?

    In this case you may just want to install an Aeromotive 1:1 FPR........ at least you'll have full control over your base pressure.

    Where can I get an FCD?

    I'm sure you can..... Its job is to keep the MAP from seeing boost pressure, so the PCM doesnt start cutting fuel.

    420A Transmission Pops out of 5th Gear (and sometimes 4th)

    A couple things to keep in mind as well......... The cable end busings (on both ends)(at the trans and the shifter)...... I personally use Amsoil Synchromesh, as its probably the closest we have to dealer OEM fluid, ATF+4 was just a cheap ass alternative and should never have been used..... But...

    The OBX header is "OK" mostly just for dress up really. Ebay specials all day. LOL!

    420A Any intake manifold swaps fit the 420a?

    No reason to swap manifolds..... The OEM is plenty, unless you're trying to make north of 600hp. Unless of course you're just trying to "doll up" the engine bay.

    Where can I get an FCD?

    Keep in mind, this is old school tech now..... Which is why a lot of us are all fancy with Megasquirt. In your case an electronic FCD would work well, which all it is, is a MAP clamp to keep the MAP sensor from seeing the full 5V..... Back when i had that setup, i set mine to max out at 4.7-4.8V

    Phantom Grip LSD insert vs CI Motorsports lsd Insert

    Ive been running the Ed Peters OBX LSD by MPx. Well over 3k (hard miles) on it, and still work very nicely..... Biggest suggestion is getting it installed by an actual trans mechanic.

    Extreme PSI Cometic HG

    Chances are they probably didnt have anymore of the size you ordered in stock , and had to have it made and drop shipped. But personally if i can help it i will buy direrctly from most makers. And ive been running a Cometic HG @20psi and have had great results.

    To me, ......its a PERFECT fit! and like ive said, ive been doing 20psi very hard pulls since i put it on June 1st. and i absolutly love it!

    strength of oem trans and clutch

    I had blown the diff out of my old trans by over revving it in first gear, but since being replaced with another used one (at the time 132,xxx on it) So far so good, using a Spec stage 3, slips quite a bit, running 20psi. everyday.

    What parts for engine rebuild?

    420A (Eclipse RS) : Real Street Performance Engine Parts, Pistons Rods Cams Valvetrain and More these guys have good parts at decent prices, ive ordered from them before and plan to do it again.

    Crankcase pressure

    :hmm: well thank god im not crazy. i havent had any oil psi problem, but my dipstick would occasionally pop out after high boost. but i finally got smart and cripmed the tube a tad. However i defiantly need a catch can, bc i get oil spatter out of the tubes coming off my valve cover after high...

    lack of power while in boost

    Yeh, figures it would take me this long after not touching the car for a few months now, i drove it on one of our warm days, and of course figured it out. Turns out i had a short in the OE harness for the entire car, and when the system did short it screwed with my AFC Neo and settings got...

    lack of power while in boost

    ok screw the sensor issue...... its come down to this, i truly believe theres an f-ing short! ive checked almost every ground, and even set up a grounding system... Has anyone had a short causing drivability problems, and extreme lean conditions?

    lack of power while in boost

    well, ive replaced jus about every major sensor witha working one,. and yet still no change, including the ecu. basically it still runs lean, and has no power (with PF off), and when u turn PF on it hesitates till PF kicks in then boosts up to 10psi then ignition cuts out, so im not sure where...

    lack of power while in boost

    ok read a lil further back and ull see what ive already done, with pf off it idles ok, but anything else is immediate lean and runs shitty, no power. im sstarting to think the ecu took a shit, or limp mode
  26. Dark DSM

    lack of power while in boost

    yes ive pulld the plugs and they look blackend like i would expect then to be. i just have afeeling that something in the ignition is breaking down, wondering if tach adpt is screwing up. but when i turn off PF it cant get out of its own way but will idle just fine.

    lack of power while in boost

    ok ive come to find that the, map, cam, and fuel pressure are ok. found out that when i turn OFF the PF it will idle ok, but will run like crap, lean, and feels like ignition is stumbling. have not checked crank sensor. wondering if knock sensor has an effect on it??? any input on this??

    lack of power while in boost

    ok guys bare with me, im doing this from my phone. have 420a boosted normal 20psi, working fine all summer until recently. now i boost up to ten psi and runs like crap, wideband says rich, however "acts" like it running lean. using PF with stage 5 cal. two step colder plugs. like i said never...

    race manifold idle

    No LSD yet, and it does spin like mad wheni hit full boost, but right now im around 20psi, and it hauls pretty good. Thinking about pushin it all the way very soon.

    race manifold idle

    No just 110 oct, and the noise was a problem from the last machining of the block, hence why i had to rebuild, and on top of that the flex plate cracked all the way around the bolts, so yeh..... and i havent had a problem with fouling, just check em and clean them if need be. And finally i have...

    race manifold idle

    race manifold idle

    Heh i think i went through more than $2000. Local macing shop ####ed me over twice, but third times a charm, different shop this time.

    WOW who even cares at this point on whats missing. You have done an amazing job at recreating that section, (a very difficult peice at that) of the car.

    down pipe

    Yes i agree definatly take it to a shop if you can and have them finish the rest, but if you wanna do it your self, determine the angle of the bend, and just get a long enough peice of pipe and have a shop make the bend how you want it, and then cut it yourself to fit. Then weld in place. I...

    down pipe

    UMMM sooo is there a 2"gap? Is that what your saying? If thats the case i would just cut a peice of pipe and then weld it in. if its something different at least get us a pic.

    Where to Buy Spark Plugs

    they didnt stop making them, they seemed to have limited to the style of brand, (i.e. Iridiums) But i believe 7's are pretty good up till 18psi'ish, and further i would suggest using 8's. But that would depend on your AF raito at that point and how hot things get, and quality of fuel. With those...

    Where to Buy Spark Plugs

    Well if your feeling squirrly and decide to go for 18psi or more, then i suggest using an 8 heat range... heres the part number and i use them in mine. You may even be able to use this PN and order them through Advance Auto... BKR8EIX

    Where to Buy Spark Plugs

    Ok well, this has actually been a discussion before, but ill tell ya. Go to sparkplugs.com, they have any darn plug your looking for. But when you look up the OE plug just replace the heat range with the number you want, when looking up the part number, And later if you ever decide to go to an 8...

    Camshaft Bearing Cap (or Tower) Bolts

    Portfueler

    No you dont need a second pump as long as long as you plumb it into your current fuel system and use an outside FPR at 55psi. But use the bigger injectors for your secondaries, considering they are gonna be doing the work when your boosting....... but i would just keep your stock injectors for...

    Portfueler

    You would probably have to call Hahn and have reprogrammed, but like the previous person said, i would just tweek it from were you are now i wouldnt even bother reprogramming it unless its way off. So try it first.....Basically Pf will read your specs from using vacumm, and the rpms, so itll...

    Portfueler

    the box itself has a serial port underneath the cover, and should have the software with it when you recieve your order, assuming you bought the software with it. But you will need to buy a matching serial cable to connect to a laptop. But the software wont work with vista, it needs windows xp...

    Bad rotors

    First off, air in the lines will not cause a pulse, itll cause a really low pedal if at all any. Although it wouldnt be a bad idea to bleed the old fluid out due to the copper content in the lines, dont wanna have any seals rotting away and swelling up later down the road. But any pulsation is...

    Bad rotors

    Well here try this, there is a store on ebay with a user by the name "drt-sport" and i got front and rear drilled and slotted combo, for about $150 shipped to my house. And ill be the first to say that ive beaten the hell out of them and they seem to hold up pretty well.
  50. Dark DSM

    Absolutely no boost, new turbo.

    i didnt have a pcv, when mine did the same thing. Hell idk replace the spark plugs too. :rolleyes:
