djmtsu's WTF am I thinking? (FC build)
 
Alright guys, might as well.

I have had my FC for a long time. Going on 7+years I think. It started its life as a lowly one owner 1990 GXL. I did nothing but drive it for a few years. She ran like a champ, and was a great car. AC was ice cold, everything worked the way it should.

Then one day, she popped. It was my fault. A very busy weekend, had a party, and only moved the car around from the garage, to the driveway, to the yard, then back to the driveway. Next morning, she fired up, idled for 10 seconds, and blew the rear seal :(

Time for a turbo swap.

I contacted Rotary Resurrection, and a few weeks later I had a complete S5 TII longblock with all sensors, ECU, harness and an NA flywheel so I could keep my driveline. I was in college, so I had to keep it cheap.

Here's the engine going in.

While the swap was taking place, waiting on the engine to be built, it was broken into. That is a whole other drama situation. They got an Alpine flip out touchscreen with DVD player, a 10" sub and amp.

So, I did an audio downgrade, and a gauge upgrade.

http://lh5.ggpht.com/_OFjbTkyhkOs/R7...0/DSC00635.JPG

When the swap was done, I had a few little upgrades. RB FCD, RB DP and silencer, craptastic catback, cone filter. No emissions. Swapped out hatchback glass for a non wiper version, and replaced the switch with a non-rear switch as well.

At this point the paint was starting to fall off. The car was rocking Mustang wheels, and handled pretty bad. Too much stagger in the wheels meant understeer at DGRR....for two years.

Next was the exhaust. I picked up an Apexi N1 Evo catback from a local guy, and gave away the shitty old one. Also added an Apexi Twin Chamber BOV.

Then I lucked out. I found some BBS vert wheels somewhat local for $75 with center caps and tool. I sold the caps and tool for $75, free wheels!

I also got the first set of JKL Engineering's bumper guards. I started the GB for them, and had them made so the driver side was a block off. Your welcome if you have these.

http://lh4.ggpht.com/_OFjbTkyhkOs/SA...s800/dgrr9.gif

Another small upgrade was the Euro-spec RX-8 5spd shift knob, short throw shifter, and new shifter/ebrake boots from Indyparts. I need a new ebrake handle, I know.

More to come.

A few goodies have been ordered.

-Haltech E6K should get here today.
-Banzai OMP block off

What I need.
- 800-1000cc injectors
- IC piping
- aluminum radiator
- boost controller
- wideband
- flange for Apexi BOV

If anyone has any of the goodies I need, please let me know.

Do I need to worry about a narrow band O2 sensor since I will be running the Haltech and a WBO2??

TitaniumTT 01-22-2010 09:44 AM

Hey DJ, I forgot to mention this in the PM, my 750/1000 injectors are going to be sold real soon if you're interested in all 4 lemme know. Be plenty of fuel for 375ish @ 85% duties.

No need to conisde the narrowband at all if you have the WB feeding it's signal to the Haltech and the display.

classicauto 01-22-2010 09:49 AM

Well, with the E6K you need to do some clever conversions to utilize the wideband. I could only ever get it to display voltages in a log, then you have to convert them to AFR outside of the haltech software. I do know there's a wierd version of the tuning software that would allow you to display AFR but I could never get it to work - although that may have been because I was using an X.

The narrowband is only useful for closed loop with the K and X, but if you get a wideband with a simulated 0-1v output you can use that to power the CL in the haltech.

Really depends on what you intend the ECU to do. I never had ANY issues tuning perfect cruise without closed loop FWIW.

Also, I have an AEM tru boost sitting around. Works excellent as far as boost controllers go. For what we're doing here that is. Its got a great alarm/overboost feature (tested first hand at 25psi :lol: ), holds a hi and lo setting, peak recall etc. Only issue I had with it is the display is digital (since its a boost gauge as well) and i found it tough to glance, read a number, and think of whether or not its where it should be etc. In that regard I prefer a needle type gauge but its just a personal preference.

djmtsu 01-22-2010 10:38 AM

How much Dave?

classicauto 01-22-2010 11:43 AM

$150 shipped?

And how did you find out my real first name :lol:

djmtsu 01-22-2010 11:54 AM

I think I will take it. I can paypal this weekend. Just PM me your info.

We have met a DGRR a few times. Nametags!!

Plus, I thought all Canadians were Dave.

Or Darrel.... wait...:suspect:

Max777 01-23-2010 12:07 AM

so will this thing be ready??? I find it funny how people were talking about some "lack of support" for Megajizz, yet a premier brand like Haltech can't even run a wideband properly? OMGWTFBBQ! Were you using an AEM wideband? THey have a weird signal coming out of them, you should try using the Innovate LC-1 wideband instead, it puts out a better signal and is more compatible with shit.

FC3S Murray 01-23-2010 12:11 AM

Car looks great man! Those wheels will look good once installed:)

djmtsu 01-24-2010 09:03 PM

Small update, nothing of real importance.

Before I started any work, I wanted to be sure that the compression is good. So jfaplanet brought over his Rotary Diagnostics Compression tester and laptop.

WOOT! All is good. Front rotor had one face that seemed a little low, but that could be from sitting for quite a few months.

Time to tear off the manifolds and start diagnosing.

IH8DSM 01-25-2010 02:17 AM

What we did with mine is throw a carb on it and see if starts that way it narrows it down for you

I used several different widebands. The AEM worked fine, in theory, its just that its output voltage never matched the reading the unit gave. They followed eachother decently but the output was always .2 or .3 leaner the display. It wouldn't matter what you used though, its a function of the K and X's software not scaling the voltage to anything, they just display what the channel is receiving.

And yes its a little disturbing that a simple piece of software hasn't been added to the unit in all these years, but keep in mind that its their cheapest entry level ECU. Anything thats better then the X does not only wideband display, but wideband closed loop and a slew of other features. As well, it DOES work on the K and X, its just a matter of being a PITA to convert.

DJ, my paypal addy is classicautobody@hotmail.com and you can call me Joe :) just attach your address in the comments and I'll box it up!

Joe Mama?

djmtsu 01-30-2010 03:45 PM

So I think I have narrowed down the problem to a simple bad injector.

I need to get it back together.........to sell it.

I bought an RX-8

Max777 01-30-2010 03:55 PM

.... maybe I'll get it later in life, but if you got a great car that works, why sell it? IMO, an RX-8 is a downgrade from a clean, rust free FC Turbo, but nice choice nonetheless.

djmtsu 01-30-2010 05:22 PM

Age, space, comfort.

Age- I am getting older, and so is the FC

Space- Now that I had a child, the backseats are quite useful

Comfort- No PS, AC or emissions makes the FC not too much fun. Add to that seats that slightly overweight people can't get into, and it is uncomfortable.

The RX-8 is not a slow car, and it handles VERY good.

Also, it won't remain stock. Who needs that crap ;)

I love my FC to death, but I'd never say my RX8 is a "downgrade" at all. Its just different.

Stock vs Stock the RX8 is just as fast as the T2 and IMHO is better balanced....

If you've got kids and need back seats, RX8 hands down, lol... ever try to fit ANYTHING in the FC rear seats?

Good buy DJ.. sorry your FC has to go though... I would agree that it sucks to sell a car thats paid for....

djmtsu 01-30-2010 10:15 PM

True the FC is paid for, but so is the RX8.

So really the FC is going to pay to help improve the 8.

93rx7r1 01-31-2010 08:58 AM

Nice FC. Sorry to hear that you are selling it. However, the RX8 should be a very fun car too! Good luck with the sale and good luck with the RX8.

djmtsu 01-31-2010 09:44 AM

Thanks. I just hope I can get something out of it. It is very clean inside, and there is no rust at all. The car is very solid. I am going to attempt to spot paint the sections where the white is peeling off.

If that doesn't work, Maaco is only like $300 :)

djmtsu 02-13-2010 02:10 PM

OHhhhhhh bad news.

So I took out the injectors. Rear primary injector was barely firing. So I bought a new gasket and got some new injectors. This morning, I out everything back in. Fired it up.

Still ran like shit. It was idling fine, and revved free, but just sounded bad.

I noticed when I fired it up, the oil pressure seemed lower than normal (45-50psi compared to normally it pushed 75-80psi). Not good.

So I let it warm up. Came back 10 minutes later, checked the pressure gauge, barely registering 5psi. Revved it, went to just below 25psi and dropped to maybe 10psi while the RPM's were up. Pretty sure it spun a bearing. :(

Oh well. Time to figure out whether to part it out, or sell it as a whole. It does run, and can be driven......if you were a brave soul.

Oh well, I guess its the RX-8 to DGRR after all.

FC3S Murray 02-17-2010 12:53 PM

bummer dude. Sorry to hear.

djmtsu 02-17-2010 12:59 PM

Its all good man. I'm just pissed I never got a chance to roll those SSR's!!!!!!

I am parting it out, there is a thread here and over at the evil forum.

Buy my shit!

nuke0907 02-18-2010 09:01 PM

get some bigger sway bars and that RX8 will be a lot more fun at the Dragon.

djmtsu 02-18-2010 09:06 PM

Working on it. I was thinking of not going to radical on the chassis. I want to drive this nearly everyday. Thinking RB sways and Tein S-techs.

nuke0907 02-18-2010 09:11 PM

i've got those Tein's and Progress Technology sways. lots of fun on the Dragon. trust me, makes a huge difference. you can still DD it too.

djmtsu 02-18-2010 09:15 PM

I've heard good things about Progress, as well as Agency Power. From what I have heard, there isn't a whole lot of difference. Anything is better than the stock hollow tube sways.

Maybe we should take this to my RX-8 resto build thread!!
