by the way the 420a (eclipse) is not a neon motor is it just based off one, and just happens to be named the same as the one in the eclipse. Both motors were made by dymler chrystler or however you spell it. not once did i say it was a mitsubishi powerplant. i was referring to the clutch design which was finalized by mitsubishi for use in the eclipse with the 420a powerplant. once again ---- mitsubishi. thanks for the support though

my good buddy is in the process of oh, a whole bunch of ---- with his 96 rs. you think the clutch deal is funny wait till you go to teardown the block and see that it is 3 different pieces.

suspension is super ------- easy, just like a honda, rear disc brakes are ------- simple as hell, just grab a gs hub (brake lines are the same). you can use gsx front 2piston calipers on the front by changing the caliper, caliper mount, and the rotor.

I dont know of any problems with the headgasket deal, his was 100% stock 160K+ miles, and weve revved the ****** to 7600 rpm at least 3 times a day.

Right now, he is going boost with 8.8:1 wiseco pistons on eagle rods, arp rod bolts, arp headstuds, oem headgasket, and lots of other miscellaneous ----. hes using the megasquirt + spark, and regulates boost strictly off of the wastegate spring.

where you from... ill probably just grab the whole rear trailing arm assemblies and the front spindles and call it a day. thats way easier then tearing them down in the yard. oh yeah should i change out the master cylinder/booster as well? maybe for a gst one? im gonna try and fix her up a little bit before i do anything. and maybe i should buy a repair manual. ---- here i go again....oh well at least this time its not on a complete pile of ---- car :P

yeah, thats what i was thinking just barely reaching 300 on 18psi? someone needs a nice turbo like this one from blaastperformance:

http://www.blaastperformance.com/index.php?p=t3t04bv

either one should work well and for the power the .63/.60 seems pretty sweet, oh well im off to work , hey slo if you can man can you link me some good websites? ive already went to 2gnt.com and was checking that out thanks to ghettoturbo. Late

the 420a makes okay numbers but I still don't like the engine. My cousin chad turbo'd his eclipse w/ 420a on a Hahn kit, and was running 5 psi non-intercooled... felt slower than my CRX NA

That's not terrible, but how built was it? just pistons/rods?

It's not Mitsubishi's fault you bought their abortion version of the eclipse. If you wanted performance, then you should have gone with their engine that was built for exactly that, and has proven to be stout as hell right out of the box. What's next, you going to buy a Lancer OZ, and then try to make it as fast as a Lancer Evo?

Well, good luck either way, but I think you're wasting time and money. Sell the thing, pick up a turboed 1g for 2-3k, and go to town!

well i would sell the car on ebay...take WHATEVER I COULD GET FOR IT....go find someone to kick your *** and then buy something that is not a DSM...trust me i have own two (1. 420a and 1. 4g63) and they both sucked ***



but if you dont' want to do that then i would recomend doing every bolt on that you can and then go get a 100shot of NAWWWWWWWS and blow it up and just walk away


no no no just WALK AWAY!!!!!

Sorry, I am not about to drive to Florida to get there and after the race have to listen to "well it wasn't fair because I'm FWD, we should do it from a roll" BS. Then once the race is over, we can even compare what we payed, dollar for dollar. I'm guessing that the amount of money I have into my car (including the cost of the car itself), is probably what you paid for your car alone. You're talking about not having a lot of money, well then why are you trying to turn a heavy *** glorified neon into a racer? A guy on our site just picked up a 1g tsi for 700 bucks. I paid a little more for my shell (2k), but it's an Arizona car, and absolutely rust free.

But the HMT all member meet is coming up hopefully sometime soon here isn't it, so what do you say? I'm ready.

Again good luck with it, but if money is a concern, I think you have better options out there man. Not trying to totally hate on you, just giving you my opinion on it all. Good luck either way.

We are from TN. as far as sites go, I dont know of any, Everything I have done to the vehicle, I have done just by common knowledge. From what I understand, and what we are going to do is rock the factory master cylinder, proportioning valve. Mainly because the GS (which has 4 wheel discs) shares the same part as the RS, and thats where he robbed the discs from.

Id keep rocking the eclipse. well rounded n/a eclipses are few and far between.
