New toy -----> update with track time

I just picked up a 1999 Mitsu Eclipse. Its a RS with the 420a in it. it has 66k miles on it and its a 5-spd. I picked it up for 5.5 from a friend. he Jsut got a '06 WRX TR. Ill get pics up as soon as possible. I was jsut wondering what yall though about FI. the Hahn Racecraft kit is making like 275 to the crank off 7psi. i figured i could do better with some HMT knowledge that i have learned over the years. i was thinking about running the t3-t4 t04e 57 trim turbo best for a 1.8 (the 420a is of course a 2L)and either dual SMIC or a big FMIC dont know yet. Jsut wondering if anyone on here has turboed a 420a as well.

i always wanted to build a turbo kit on an n/a eclipse, there arent any of them around here, it would be fun to beat guys with the 4g63 then pop the hood and show them its a 420a :y i think a stock 4g63 mani should bolt right up, then find a used 16g or 18g that will bolt right up, slap a cooler on it, build some chage pipes, throw in a set of 450's and an afc and run the hack on that bitch, it should hang with some modded 4g63's

pretty sure the 4g63 mani isnt even close...not sure what kind of tuning stuff is out there, most ive heard of just set up a return line and run an fmu with a base adjustment. A friend of mine used to run 23 lbs on a built 420, scary car. they can spool some big ass turbos, id stay away from the hahn kit because i wasnt impressed with it at all (log mani, goofy turbo)

im also pretty sure the 4g63 mani wont bolt up. my friends got a built 420a in his eclipse and he put down 296@19psi. Pretty weak for a forged bottom end

he has the star stage 2 kit

pete who are you talking about. there is also a red tubo neon in bristol with the hahn kit.

its about 230ish whp.

if u want to do a hmt kit, i could slap u together a 420a log.

woah hotsex i need to sell the rex fisrt but ill keep that in the back of my mind and hit you up when the time calls for it. By the way anyone running a dual SMIC Setup. Also do i have to run the hack or is there another way to control fuela nd timing and what not. Im looking to beat my boys stock TR - Ej25T 230hp at the crank and AWD with my FWD 420a. It will be a big task but im up for it. hell he said he would be impressed if i just turbo it.

Ive been looking at the hahn racecraft kit and trying to figure out how they jumped a grand in pricing just by turning up the boost to 8psi and a bar and plate intercooler. I mean that is 2 gs for the stage one and that jsut isnt worth it. Hey hotrex what size piping would you use for the manifold n ----? they are running the super 16 g on both stages so i think i may run the same unless i can find a decently priced t3/t4. also does anyone knwo what size the bar and plate they are running on that stage 2? i mean ill jsut pick up a JRC 8" and after i built the kit HMT style ill pic up some internals and boost 2 bar.

don't go with dual SMICs....get a nice FMIC.

Yeah im just gonna go with a JRC 8" FMIC. I Still need to talk to a few DSM guys so i can ask about the charge piping cause im just gonna order some bends and use silicone couplers and do all the piping up myself probably at my old HS.( My old shop teacher is OG like that he also has mig/tig/arch welder :) ) Im going to run a 3" upgraded Dp for a GST off the turbo and then use a kteller.com catback kit to do up the rest. Oh yeah Hotrex i wont need it yet but i was wondering if you can weld on a WG flange to that 420a log you offered to make. im going to run an external 38mm tial...almost forgot would like it to be ac compatable ( Sorry for all the request man but i live in florida - ac a must). just hit me back up with the price and what not.

possibly megasquirt for FM ???

squirt seems like the only viable option. Anyone got a good site to read up on it (non-forum site)?

http://www.megasquirt.info/

first thing on a google search. ;)

I thought the 420a was complete junk for boost. Comparable to the d15b7 for us Honda people.

420a=crankwalking, head gasket blowing monster. I had a 95 eclipse witht he 420a in it. I bought it on a 4 year loan, I sold that bitch 2.5 years into it after going through 4 head gaskets and a cam seal on a car that had i/h/e.

I would have sold you my 97 4800.. I hate this ------- car

sadly enough, as much as I hated it. 2.5 years later, I miss it. :(

basically.

My cousin has the Hahn turbo kit on his car man.. and to be completely honest.. its slow as balls :3 we were running 5 psi which I know aint ----, spooled up low and it was just kinda slow from there, driving my moms van afterwards I think the van was faster :l

Using the Hahn kit and megasquirt with some 750's, I was able to tune 300whp even out of my buddys turbo non-turbo eclipse. This was 22psi, that turbo is a little small, you end up at like 16 psi by redline. I'd personally build my own log mani, and use megasquirt. Doing it liek that, it can be quite a cheap kit.

His motor is built.

Lets just put it this way, owning a DSM is like having a retarded child, you love it to death, but you are always having to fix ---- on it and you hope it doesn't embarass you in public.

Sorry i havent been around was working two jobs there for a little bit. Anyways i still need a price on a manifold from you hotrex. I imagine it will be using a mc master kit?

Yes and some people are still turboing that motor as well

However if you push it to 6.5k every time you shift, beat on it and treat it like ---- cause its a mitsu. , and roll around with i/h/e like your even fast anyways then somehting is bound to go on you. Also the CW issue doesnt apply to these motors they are talking about the N/A 4G series and most of the time CW is caused by the 2nd gens difirentiation in design of the oil squirters as opposed to the 1g design.

No offense sinister you should of slapped your cousin for using the hahn kit. if he jsut bolted it all up and didnt tune it then he is running the stage one kit that cost like 2600 bucks and is running 5psi non intercooled. that kit only makes like 200 to the crank in a car that weighs like 2700 lbs stock with no one in it. also that kit is using a super 16g that comes off a stock Evo 8 however keep in mind that the evo is running 8.8 c/r and cccording to Mitsubishi, the twin scroll turbo is making 19 psi at wide-open throttle at 3500 rpm and 16.2 psi at WOT at 6500 rpm. it makes 276hp@6500. so basically at 16.2 psi the 4g63 (2.0L) is making 276hp to the crank (http://www.sportcompactcarweb.com/fe...303scc_lancer/) . thake that same turbo put it on another 2L and only run 5 psi.....wont seem to impressive.

Yeah you make a valid point.. I also asked him what fuel management he was using and he gave me this kinda look --> ???

my friend got a 91 laser rs same as teh eclipse we bought everything from the local dsm parts seller it's now our little project i guess but his is n/a also we got everything we needed for 500 harness,mani,ecu,injectors,masey,throttle body,intake mani,02 housing, intercooler,bov,and all the piping now were just trying to get a 14b,
we can get the t3 t-bird turbo's cheap will they work or will we have to get some ---- fabbed up for it?

Re: New toy ------> update track time

I went to Bithlow here in orlando with my rs to see what is would run stock on all season tires. the car has 67K miles on it and i kept in the spare,jack, and my audio stuff ( 2 crossovers and my amp along wiht my speakers - sub). i just wanted to see what it would run basically as if i pulled a 99 eclipse off the street and ran it. I was my first time to the track and i averaged a 17.6 quarter ( i weigh like 300lbs) my 1/4 got worse every time because i didnt have traction. by the third run i nailed a .091 r/t aginst my friends 06 wrx tr (he hit a 14.9 in the quarter and a .41 r/t) I will try to get the time slips posted up but i need to find a scanner.
