I've been meaning to do a build thread for a while, and just never got around to doing it. At the time when I first bought my car I didn't take a whole lot of pics so I didn't want to bore everyone with just words.

Well this is it......The build! Lets start with the boring stuff first ;) I've owned 5 DSM's in my life(so far). It started when I was 14 years old, I know y'all aren't going to believe this but it was because the Fast and the furious movie.....Crazy, right!?!? Haha anyways, my dad helped me pick up a 93 eclipse gs, thing was an absolute slug and a tank. I then picked up a 91 Plymouth Laser, a 96 Eclipse Gs, and a 96 Spyder Gst. Then there's the car I have today which is a 1998 Eclipse Gsx. I knew not a damn thing when I got my first DSM, then slowly started searching the forums. I absolutely loved to read and search over different and potential things you could do to these cars. I was hooked.


I bought the car in the summer of 2010 with a supposed "lifter tick" according to the lawyer I bought it from. Well I got there to buy it and started it up and knew right then it wasn't just a lifter tick. I ended up getting it for a really really good deal so I was happy either way. I lived in missouri at the time, and the car was in Illinois about 2 1/2 hour from me. Luckily my dad is super awesome and got me a truck and trailer to go get it the following day after finding it.

I'd like to also state that I'm by no means a photographer and a majority of my pics were taken with various shitty phones. I would like to get a nice camera sometime in the future but till then we're stuck with this ;)

Here's the original CL ad. Yes it was a pic taken of a computer screen. Also yes I hate the paintjob just as much as everyone else does.

Here's the day we went and picked it up

I know, I know, looks like a toaster was used to take the pics :p

Anywho, well I got the car home and didn't really do much with it seeing as I was quite sure what was wrong with it and didn't have the space/means to find out. So my next move was to take it to a shop. There was a very reputable DSM shop decently close to where I lived. I didn't want to take it to a shop by any means and still kind of regret doing it to this day. Well I took it to this shop and got news back that the rod bearings on cylinder 1 and 3 had spun. Well I figured while it was there I might as well get all the maintenance taken care of as well as a few goodies. It ended up sitting in his shop for damn near a year. I couldn't of asked for better work though.

I had asked the shop aide to take pics of everything for progress for this very reason, but that didn't happen! :( I had them do a complete timing job as well as freshen up the bottom end. I kept the whole bottom end stock, but had to have a rod resurfaced which I didn't want to do AT ALL but was reassured it wouldn't make a difference. I went with some standard ARP headstuds and a mitsubishi MLS head gasket. I also had him do a BSE, replace the oil pump assembly and new timing covers while he was in there.

Well close to a year later I finally got the car back. I was SUPER excited. The car came with an Evo 3 16g, RC 550's, wally 255, 3" cat-back exhaust, Megan racing 3" down pipe, SAFC-2, Greddy 24v FMIC kit, Greddy type S bov, Eibach prokit, Tokico Illuminas, crappy Ebay halo headlights, adjustable cam gears(still have no clue what brand to this day) and some heavy ass Kazerra KZ-A wheels. I won't bore you with the rest.

Well After I got the motor good and broke in I started getting a little power hungry. So I began to search the forums on more of a daily basis, and by daily I mean I'd spend all day on this site. Even at work during free time I'd be on here. I've learned so so much over the years thanks to this site. I learned I had a setup good to get me to the 300ish hp area or 12's. So I started reading more on the tuning side of things. Well after learning more on EcuFlash I came to the conclusion the Safc-2 had to go! I was astounded by the possibilities there was with this. So I sold the Safc and bought a Tactrix 2.0 OP cable and had at it.

Now you somewhat know the story behind everything I'll start timelining from here.

January 2011

Fast forward about a year or so, not much happened here due to moving around alot. The cars been my DD and haven't had an issue with it at all, but the gas mileage hasn't been the greatest. I learn my front o2 sensor is dead so I decide to replace it. Well as my luck has it the o2 sensor seized and broke off in the o2 housing. Luckily I had a spare tubular one lying around from my previous spyder. So off comes the turbo!!

IMAG0051_zpsdb6ff8e9.jpg


I had thought all the gaskets were brand new and I wouldn't have to worry about replacing them IE: turbo to mani, mani to head, turbo to o2 housing and o2 housing to downpipe. Boy was I wrong, I HAD paid for new gaskets but they weren't new by any means. :ohdamn:

IMAG0053_zpse7a2a823.jpg


Well I ordered new gaskets and decided to clean the turbo up a little while waiting. The 16g had no shaft play at all after who knows how many years it had been on previously. I was impressed, it had definitely seen its fair share of use

After that I had just enjoyed the car and learned more of the ins and outs of tuning.
 
February 2012

With the stock clutch slipping on me I decided it was time to replace it. I thought might as well "upgrade" it while I was at it. I had seen and searched on a lot of clutches and the XTD kit caught my eye. I know, Ebay shit blah blah blah, this is the only thing I have gotten off Ebay for this car and had heard nothing but good out of it. So I ended up going with the XTD stage 4, 6 puck sprung disc.

Old clutch/flywheel/Pressure plate!

Well since I was having to replace this I thought hell, I might as well get a lighter flywheel while I'm at it. So I found one on here posted as like new condition for 7 bolt AWD, well needless to say the flywheel I got was nowhere near like new, nor was it for an AWD. :nono: Due to this I had to use my old flywheel :( Yes, I had it surfaced.

Flywheel that wasn't correct.

Everything together.

I love the way this clutch feels, has held launch after launch, hot lapped track passes, and a lot of boost! I have ran into a minor mishap with it though I'll cover later on.

February 2012

I quickly began to get sick of boost leaks and always having to take the damned front bumper off to check for them and mess with the intercooler, so the Greddy 24v Frount mount had to go. I researched alot on all the IC kits out there and decided the VRSF kit was the one I wanted to go with. Well I found an uber good deal on one with a junk HKS knock off ssqv bov(actually held fine).

2012-04-23205154_zpsf06f893d.jpg


I instantly noticed a difference with this over the Greddy kit. Throttle response was lot more crisp and boost held stronger to redline.

--------------------------------------------------------------------------------------------

June 2012

I for some reason absolutely couldn't stand the wheels that was on my car, one main reason was one was bent, all were curb rashed pretty well and just overall just shitty wheels. So when I had 2 tires that blew at the same time I said screw it I'm going to get a new set of wheels. I found a decent set of Motegi FF7's for a real good price with new tires. I wanted/still want different but these will do for now.

August 2012

The more tuning and tweaking I done to the setup the more I wanted, so after maxing the RC 550's out I stepped it up to some PTE 880's

20120818_174425.jpg


RC's top, PTE's bottom

Along with that I decided on a new wideband setup, I went with the Innovate MTX-L. I originally had the LC-1 and loved it but thought what the heck.

2012-04-25183756_zps4a8ca34a.jpg


Also I had hated the halo projector headlights that came with the car, I wanted OEM so a local to me(cabot2g on here, check out his build) was kind enough to offer up a trade for his OEM headlights for my halo's that his son wanted.

September 2012

After getting so used to EcuFlash and tuning and reading up on E-85 I had thoughts of wanting to switch over. I came across a great deal on some FIC 1150's so I snagged them. They would get me by for right now. I didn't go straight E-85 and didn't switch over right off the bat, but man I love these injectors and how EcuFlash controls them like they're stock.

FIC top, PTE bottom.

Little E-85 love ;)

November 2012

Well, the XTD clutch decided it didn't want to maintain its springs anymore, or whole center section for that matter. I was driving about 15 min. from home and noticed that something was terribly wrong. So I get home, pissed off because I know what's happened. So I start to tear her apart.

20121105_193112.jpg


Well I called XTD up and explained to them what happened. They were extremely helpful, not only did they refund me my money completely, they gave me another clutch kit for free, revised this time. Took maybe 2 emails and being on the phone 5 min and the issue was resolved.

Also with this I decided this time around I'm ordering a new Fidanza flywheel. The clutch feels great to this day and has even more track passes and even more boost than the last one.
 
November 2012

It's the last TNT of the year for our local track and I wan't to see where my setup stands for a before and after kind of things. This was straight pump 93.

The tracks only a 1000' mind you. This is on 22psi, little timing advance and it was running a little more rich than I had liked this day for some reason. I was happy. Needless to say though. I'm the right lane.

20121124_184042.jpg


10.3 @ 100mph for those of you who are blind.

--------------------------------------------------------------------------------------------

January/February 2013 HOLSET TIME!

Well I absolutely LOVED my 16g with E85 on 28lbs of boost. Thing was a beast that spooled up amazingly. I just got, well, bored with it. I had been searching a lot on turbos and decided I wanted to see if I could find me a Holset 35 with BEP bolt on housing.

I found a guy on a FB group that was looking to trade his Hx35 with BEP housing and 38mm EWG setup for a 16g or 20g. Well I initially contacted him not thinking anything of it or really expecting anything to come of it. Well to my surprise he was really interested in trading me my 16g setup for his Holset setup. Well we end up trading and I couldn't of been more excited!

What it looked like when I first recieved it.

20130129_181901_zps7b422407.jpg


I decided I wanted to clean it up and make it look like less shit. So I decided to get some aircraft paint stripper, and some VHT ceramic high-temp coating go at it.

After getting it installed, still getting the kinks out.

20130205_211609_zps09627928.jpg


I had it at 25-26psi with moderate timing advance and this thing pulled like no other. I was beyond happy with it.

This was the point in my DSM career of what could go wrong will go wrong....

Me and a bunch of my car buddies(all v8 guys) decided to make a trip down to MIR(Memphis International Raceway) for their opening day/TNT. Well I get down there and for some reason my AFR's kept going extremely rich. It wasn't the tune, boost leak is all I could think of at the time. I had no way to test it, down there. I ran two times and both times I had a vacuum line pop off. First line was the line to my FPR, second line was the wastegate, leason learned clamp every single line down. So I didn't get one good pass in due to stupid issues, so I decided I better not test my luck and leave before it gets worse, so I began to my parents house in Mississippi to visit them.....This is the point where everything turned to shit.

I had just upgraded my brakes with new rotors and brake pads and didn't bleed them as good as I thought apparently, so I stopped at an autozone to grab some brake fluid and bleed them before something bad happens. Well I got done bleeding them in the parking lot and go to head home. All I see is a ton of smoke come barreling out from the front of my car. Upon investigation my oil filter had came loose for some reason(find out later) and drained all my oil in the parking lot. Well I bought more oil and tightened everything back up and all was well or so I thought....I keep driving about 30 or so miles and all of the sudden notice my knock gauge go through the roof!! So I pulled over but the motor had stopped running on its own by then. My heart sank :( I got it pulled over on an off ramp and had my dad come pick me up. While waiting on him I decided to look things over, and take the oil filter off. Sure enough the seal on the oil filter had knotted up and it was almost off the filter stud.

He was soooo pissed off here. Poor guy.

20130224_094402_zpsa0bf866b.jpg


Note, I got that hood after my other was back into for super cheap. My hood got really dinged up. Glad we could clear that up :p

Anyways, I finally got it back to my home and got it over to my friends shop.

And this is where the build begins!

March 2013

After looking at a lot of bays and noticing how clean they can be and cluttered up a lot are I came to the conclusion I want to do a nice little wire tuck!
I'll also be repainting the engine bay and deleting anything I can. I want to get the weight of the car down substantially while still retaining street-ability.

So first thing first I pulled the engine harness.

20130316_202840_zps5fac1b5d.jpg


Here's a lot of the useless wiring I've pulled so far.

20130316_230715_zpse41a555e.jpg


I'm not done with it yet.

I went and worked on it today 3-27-2013 and got a lot done.

I pulled the main harness.

20130326_174218_zps21ed6455.jpg


Did a little work to the bay, still a longggg way to go.

20130326_174023_zpsb52cd5d5.jpg


I'll be spending a good amount of time working on the harnesses, I plan to move the fuse box to the glovebox area or under it.
