Nelsonmxmarc 1993 GTSt Type-M Build / Tips-tricks for HCR32 (Skyleezy!)

[nelsonmxmarc]

You fools! They're there to brace for horizontal play, the fmic is bolted into my rebar via 3 bolts, it's not moving lol.

It's actually not 2 layers.. It's leftovers from our other projects; 2x2, 1x1, 2x glass and 1x1 backing.. 5oz through.. Looks are deceiving ..

We bench tested lateral strength and rigidty at 184 and change foot lbs before shattering..

Anywaysss my diffuser prototype is done.. Which actually went along much quicker than expected.. I just began with the final mold and the first mold of my diffuser.. Should turn out really good.

I'll post pics in like.... Mmmm 20 min when I get home from the garage.


On another note, besides cf.. I just adjusted the tps, installed the rest of my engine goodies.. Then I tackled another little doozy..


A while ago I bled my brakes and managed to put the pedal to the floor with ease regardless of how much air I was able to remove..
Well today skimming through old topics I staggered upon a guy who mixed up the left right rear.. Fml
both bleeder plugs were at the bottom, ie feeding 0 fluid to the caliper, rather back out into my vac system (mity vac bleeder).. Anyways, problem solved lol.

Key note, bleeder up.

Next is.. Well, off for a tune

[nelsonmxmarc]

So exciting!! I just realized photobucket had their own iphone app, that just saved me like a good 30 min of effin around.. epicccc

Ok, so here's the first prototype complete.. Didnt have any clear gel-coat left for after the 1500 grit sand, so i used an OK automotive clear.. Not a big fan though.. But hey, first edition, what can ya do.. Also note i didnt particularly pay attention to the weave consistency, only because this thing was made entirely of scraps.. LOL There's actually 1 whole strand missing from the 2x2, but you kind of can't see it .. sort of..







Bed timeeeeeeeeeeeeeee

[M13]

looks good for a proto, but you know you may want that extended a bit more because right not it's not doing much.

[nelsonmxmarc]

Yea, its unfortunate becauase im basing it on a GTST hood at the moment I haven't been able to get my hands on a GTR hood to test fit, and josh's car is pieces awaiting engine removal. At least now i can build from this for different variations in the future..

Howeverrr, as far as the gtst hood goes, it actually lines up perfect! At the front where the hump comes down, theres the raised section inside that rubs against it as it closes creating a solid seal.. But yea, GTR hood may be different, i'll need to extend it an inch and a half and about 13 or so degrees up.. I'm planning to extend the panels above the lights as well, but again with the gtst hood, the humps fall into these light areas and leave 0 room for anything.. Damn i hate this massive heavy hood..

Thanks for all the incite dude!

[nelsonmxmarc]

So today i decided it was judgment day.. And judgment day it was.

Put in my AFM, filter, tightened up wtv else was left etc..

Turned the key - pump primed.. STARTED.. Oh glorious day...


Ok so things to note;
My 'engine' only mods consisted of n60 maf (for now..), gtr injectors, gtr fuel pump, gasket matching, honing/porting runners and manifold, r34 neo 6 turbo and 3" / 1.5" divorced wg split dump..

When the car ran, at first, hit a solid 14.7 on the cold start map which to me seemed strange considering the ECU hasn't been tampered with yet.. Anyways, 30 seconds in ecu swaps to running tables and it cans it to >10:1, ie. uber rich.. So smokey the bear paid a visit and i was soon standing in a cloud of fog.. But none the less, it runs!

I was concerened that with meddling in the wiring loom for the injectors or maf, or anything of that nature may have caused something to stir, but im actually quite glad that things are going smoothly!

After this brief warmup, i was able to then swap coolant and oil as both were affected when transplanting the new turbo.

...

And this right here was the greatest moment for me - taking it down from the jack stands.. I did the back first, then proceeded to do the front. As i pulled both stands out from under the front subframe cross member, i sat back, grabbed ahold of my hydraulic jack and turned.. as it came down, a cloud of dust, and for some odd reason, the Star Wars theme song magically filled the room..

I had the most epic smile on my face, nothing like 5 months of hard work coming to a close..

Now i know this build thread isn't impressive compared to most, but when you take into account the amount of labour, driving around to collect parts, ordering parts and actually making the time to get things done, it's been a hectic 5 months..


Heres to recap all the work done in the last 5 months, as well as the month leading up to storage;

Install 3 gauge slot in vent
Installed new windshield
Installed GTR rims
Hicas lock out
Remove all hicas lines and solenoids
electronic hicas delete
Power steering cooler reroute
Remove; intake plenum, runners, cam covers, cam timing cover, SMIC and piping, turbo, downpipe
Change AC compressor
Change all top end gaskets
Install din slot with boost gauge
Fix rear leaking taillight
Drop bellhousing
Remove clutch and throwoutbearing
Have flywheel machined
Reinstall new clutch/throwout/pilot bushing and flywheel
Reinstall bellhousing
change tranny oil
change diff oil
remove and rebuild all 4 calipers +paint
change to hawk hps pads
have rotors sent for machining
reinstall rotors and calipers
install stainless braided lines
change and bleed brake system
change and bleed clutch master
fit FMIC and piping
cut rebar/bumper
fit carbon rad cooling plate
install aem wideband and sensor
install new downpipe

..... I think that's it..?
Damn that seems long.. if i missed anything i'll be sure to add it..

Anyways, next is ECU retune. Daughter board will be in this coming week i hope, then that way the car will be drivable until dyno date mid march.. Will be nice to have it on the road again!

Big thanks to Marc-Andre (Klys), my car is now home and running!!!

Had the biggest smile on my face last night when i first took it out!

Issues i had off the bat;
1. Idle - this was due to the main AACV valve adjustment that you can find on page one. It needed a bit of a fine tune as it would continuously hunt for proper idle.
For those of you with idle issues, i definitely recommend pulling the AACV (Make sure the gasket survives, if not, change it otherwise vac leak..), cleaning it thoroughly as i did, and then fine tuning your idle adjustment via this screw..
This screw basically fine tunes an adjustment via the solenoid, which is tuned to the ecu. By adjusting this, you're adjusting tension on the spring and solenoid which, with the ecu, adjust idle. I have had 0 idle hunting issues at running temp so far.

2. I never really went into detail about belt tension in terms of the AC compressor, so i went by feel. It turns out i tightened the pulley too much, as well as the belt.. You'll get an audible whine if the pulley is too tight, as it's rubbing against the washer/coupler that cups it in the proper position.

3. Coolant still wont burp after swapping fluid with a closed thermostat.. I may have to dwell deeper into this but for now temp's are A-OK, and i have been releasing any air i suspect from the bleeder screw on the plenum.. So far, i've simply added 4 litres of water and a bottle of water wetter to the already premixed coolant that was situated in the heater hose/core and block before/after turbo. I plan to do this more thoroughly later as i said, but if my calculations are right (from what i removed/put in), i should be good for roughly minus 20 degrees celsius; nearly 70/30 mix..

...

So far that's all..


Klys really helped me out though, so a big shout out to him..

He met up with me downtown last night after work to help show me and program for me an EPROM for my ecu. After an hour or so of explanations which i'll have to research again due to the complexity of it all, i had a board in my hands and ready to go! Used a tune he had been working on for his father's car which is generally characteristic of mine minus the turbo..

Powerband is as such so far;
Stoich at idle
Rich until boost, AFR ~ 11.5/12
Full boost @ ~3450, AFR ~ 12
6000+ range, AFR ~ 11.8

So rich, yes, but running very well, no popping, no misfires, no severe lag, and butter up to 7200..

TPS is set at ~.49, which i assume, higher than .47 which i had it last year, was perhaps the cause of my sudden cut out at WOT in 3rd at 5000..

Anywhos.. Car sounds incredible, no vac leaks, fuel pump is nice and strong, 0 hesitations @ 6 celsius, no boost spikes and running a steady 10.4 lbs at the moment.. Hoping to see 14.5 this week if the weather permits.

I'll also do a follow up with temps this summer, and to how it has been reacting in terms of the mods and etc..

Next mod is of course nistune, which Marc will be explaining to me as well lol.
Really knowledgable guy with a lot of patience, couldn't be happier with the help he offered me last night!


I'll snap some pikchas later!

[archaeic_bloke]

congrats bud, don't forget to take me for a spin after class tomorrow! hahah oh yah and bring those wheel studds!

honestly, im so jealous your car is running ,,,,lol

[frankiman]

another running beast! sweet

and yeah Marc is very knowledgable, why? he used to study at ETS!

i'm really eager to see your car sometime this summer

[nelsonmxmarc]

Lol no worries josh, i have your din plate as well.

Yea for sure Francois! We'll definitely have a solid meet this summer (many i hope) and definitely some track days!

I just pm'd you about the diffuser details, let me know what you think.

Like i said, ill have more info following thursday as ill be stuffed in midterms this week.. i have another next week and 10 page paper coming up as well, but i'll do my best to get some of these products released..

My Rad cooling plate is actually finished.. as i got my hands on a pretty solid one to use as grounds for a design.. So, that's finally done! i'll post pics this weekend

[nelsonmxmarc]

Turbo is blown.. less than 2 hours of driving at optimal conditions limited to 11 psi boost by the OEM actuator.. Whattt theee fuccckkkkk..

Absolutely pissed off..

..

Took Josh for a quick ride after school - first time hitting 6500+ rpm as i've been waiting to break everything in.. 0 boost pressure, and an absolutely insane whine coming from my filter.

Ultimately i knew what it was.. But i called the guys at Autoworx for a second opinion - pointed at boost leak as fault which made sense, and what i had hoped for..

But NO! Low and behold.. the bearings as i suspected when it arrived, are fu*kin toasted.. Too much up and down play, fins snipped the compressor housing wall and wham.. looks like a freakin pencil went through there..

I'm hoping Adam from Feast replies soon, as thats whom i bought the turbo off of.. It was in "used" condition, however i dont believe this constitutes "GOOD to PERFECT" condition for a turbo...


oh well.. FML

[nelsonmxmarc]

Ever wonder what up and down play results in at 11.7 psi?







....












Crying..






And this is what it results from...






Yes.. 122 km and 11.7 lbs of boost.. BOOSTED TODAY! FOR THE FIRST EFFING TIME!!

Josh and i were stumped...

Here are my theories;

Up and down play was minimal but present at time of purchase.. Could have been the result of high spool + intense bump that me and josh hit that made the wheel touch the compressor walls = this..

2. Old or fragile blade, as all blades had small imperfections = crack = break off compromising other blades too = off balance = fries bearings...

[archaeic_bloke]

well id like to say a few words about marcs car now:

in that breif moment i was in the car i believe my exact words were: "ohhh mmyyy goood this thing is a monster!! the power is just un real!~".....

there really is no explanation as to what would cause the turbo blades to explode like that other than shaft play.. i mean for sure nothing got sucked into the turbo. like i was saying before, you're both lucky and unlucky,... unlucky that it happened like that, but also SUPER lucky that the engine wasnt damaged! and my god, where did the shards go? the only place i can think of would just before the intercooler, you'll have to take that off and check it over. you should maybe also do a compression test quickly just to be certain nothing effed up the motor.

you have my sympathy marc, but i think each experience provides an opportunity to learn and grow... can we expect to see more power after this incident? whats ur plan?

[frankiman]

is my guess

[nelsonmxmarc]

LOL
Perhaps the price will be lenient as it's coming from Adam once again..

Please Adam be nice! :P

This is the quote that did it. You practically jynxed today! YOU FOOL! lol

And let me know when you want to cut the carbon, we can do it at work as the saw is much much much easier..

oh and sorry for leaving in such a hurry.. im sure you could tell i was about to sh*t all over the place loll
