Minor update w/pics;

As already mentioned, the MAP sensor has been relocated back behind the Intake plenum, just above the distributor....



The MAP sensor's vacuum line has been shortened substantially, and although the jury is still out on whether there is any real benefit to this or not, the reduction in clutter is worth this mod alone. In the pic below, you will see the stock vacuum line on top, and the shortened one just below it....

Update:

Both the exhaust manifold, and intake plenum have been blocked off with some thick metal sheeting that was cut to fit (I'll post pics later on tonight or tomorrow). I was just invited over to Atco tonight, so I might (if we go) just have a NA base run for this thread...

Hog wash, my car ran the best times with the EGR blocked off, just make sure you run 91 or more octane since the combustion temps will be higher. If you run cheap gas, it will detonate and cause the ECM to pull timing .

17.1 @ 75mph was my best, this was with 1.6RR's and the EGR/smog delete. However, Pairtoe, you will get an SES light after highway driving and the code will read "EGR" because it's not there, lol. If you leave the EGR connected to the ECM, but not the manifolds there will be no codes .

Street Lethal

iTrader: (16)

You reiterated exactly on what I was saying....

The EGR disables at WOT, and re-enables at part. With the EGR blocked off, the car will run absolutely fine, but with the connector removed, this will trigger the SES light, and throw the ECM for a loop. Leaving the connector in tact will act as a buffer, just until you either disable EGR from the PROM, or run another fuel management system that doesn't require it, entirely...

Continued update from last night;

Here is a pic of the block off plate that I fabricated out of aluminum sheeting for the intake plenum. The gasket believe it or not was still in good shape, so I re-used it, however, simple gasket maker would have been fine. An additonal picture of the block off plate for the exhaust manifold will be coming shortly, need to re-charge my cam....

Update continued;

Here is a picture of the exhaust manifold block off plate (it's made out of steel, not aluminum like the above). Remember now, this is only temporary until I have the MegaSquirt dialed in, as well as the turbo headers installed. But for now, this will allow me to drive the car around....

The smog pump inlet will be capped as well, just need to get my lazy butt to Loews, and/or Home Depot some time today....

On my way now to the hardware store to get a plug fitting, but wanted to quickly show you just how much room now resides on the passenger side, especially with the stock coil w/bracket assembly being removed....

Final pic of the night;


Been seriously contemplating the adaptation of an old LB9 TPI setup that's been sitting in my garage for years. My cousin wants me to go this route, especially w/the MegaSquirt calling the shots. It's just a matter of fabricating some aluminum runners (mainly the lower side), and sealing off the second to last port(s) on the plenum. I'm liking the idea more and more, but will know for sure though once the MegaSquirt get's here....

heh i can already show u a tpi plenum mated to a v6 motor the opnly real benifit is the larger tb

btw check ur pms on ls1

iTrader: (16)

Yeah, I have that picture already. Gaspar and his friends already did this swap years ago on a friend's V6, which is why he's encouraging me....

That's quite the benefit, no....?

daves12secV6

iTrader: (3)

depends on how u would liek the car to drive with an on/off switch for the throttle stock tpis's are what twin 48mm? and a stock v6 is 54mm iirc.
so u need to figure out the surface area difference between the 2

Street Lethal

iTrader: (16)

My cousin is smiling as I write this, he know's bro.....

daves12secV6

iTrader: (3)

best bet is custom plenum with a mustang 65mm tb the worst thing about the tpi tb is the oval shape silicone couplers dont like to stay atteached no matter how hard i tighten up the clamps.thats why if u look at mine u will see the lil weld beads in 4 spots around the lip on the tb, even with those it still pops off now and then

Street Lethal

iTrader: (16)

I will say this much, I didn't realize exactly how much hood clearance I have in there. Accidently closed the hood with the TPI intake sitting on top of the stock 3.1 intake, and the hood closed no problem. It didn't even scuff the hood in any way whatsoever! Impressive....

Need to get the MegaSquirt in, the above TPI method was just a possible concept....

daves12secV6

iTrader: (3)

then again these would look really good under the hood and there a direct bolt on made just for the v6 motor




lil exspensive at 325$'s though

Street Lethal

iTrader: (16)

That's the thing. I can port out both the TPI plenum along with it's throttle body (which I already own <smile>) for nothing, and adapt it to the V6 LIM. The only cost would be the fabrication materials (work itself is pretty easy to do). Yes, the stock TPI setup chokes the LB9/L98 engines, but when you consider I'd be adapting it to an engine literally half it's cubic inch displacment.....

We'll see though, it's just and idea that I am flirting with....

Not too big of a fan of the one I think you have in mind though;

Might wanna try a ported turbo Buick tb. A lot cheaper and the tps/ iac should work.They go from 48mm to 62mm i think. Should be more than enough for a 3.1 considering it gets the 3.8 into the 10's.

Looks like the 3.8 guys at e-town may have some competition.....

Thanks Pete, I'll definitely look into that....

The GN guys over at e-Town don't fool around, especially the MAGNA boys. Looking forward to battling it out with them on the dragstrip....

Yeah I met up with you guys, a while back with Paul and Shawn(GN's), Had my TTA there. The interior on that firebird was sweet......

Haven't had a chance to get back since, too much work....

Street Lethal

iTrader: (16)

What a small freaking world lol!!! You definitely need to get out there with us on Friday night's Pete, as the competition is really getting intense. Last time out, Paul was supposed to line up with a, supposedly, low 10 second '68 Firebird, who at the last minute backed out. Paul ran Shawn in his place, and Shawn actually got Paul in the 60 foot. Shawn's car is sick.....!

The engine compartment is coming along nicely, as everything is getting tucked away in preparation for the turbo's. Next up is the exhaust system, as well as the installation of a MSD-6AL box that I had lying around the garage...

Here is a pic of the restrictive stock exhuast system from the rear;

PETE

iTrader: (1)

An 11.0 car on 18 pounds with a 45A, I'd say so!

That turbo isn't supposed to like anything below 25psi, not even close to efficient at that level. Needs a larger set of injectors and a retune and a 10.90 is not out of the question. I joke with him all the time about what it'll do at 28-30 psi. I have about 3hrs seat time in it. Too much work and the busy season is upon me, I'm gonna try soon. I really wanna set it up on the wideband first before an all out run.

What's sick is how he nails the tree everytime. He'll light up just about anyone...

I believe Paul is the very first, and last, Grand National running in the closer lane....

That motor is untouched. Stock TTY bolts in the rods, no steel caps/girdle. It's amazing how fast that car is and how long it's stayed together....

Small update;

My cousin made a few adjustments to the stock VE tables (can't wait for the MS to get here, I hate PROM burning). Installed a set of new plugs, w/Accel wires, and the engine is now running extremely strong for what it is. Still trying to determine where to place the MSD box. Need to get the 1LE heater box in there (waiting on a gasket I'm still fabricating, I don't want to use gasket maker). Should have a run in tomorrow night, just need to take care of a hung caliper first though....

firstfirebird

iTrader: (3)

What did you use to block off the lower EGR hole? I used a threaded plug and the exhaust kept blowing it out. So I made an aprox 3"x3"x3/16" plate that covered both holes and drilled/tapped the manifold to accept larger bolts (IIRC 10mm 1.5).

Street Lethal

iTrader: (16)

We used the stock air tube fitting, albeit with the tube removed, and the plug welded completely shut. First couple of minutes, both the welded plug, and steel plate had leaked a little, but then welded itself to the exhaust manifold in no time....

hey rob gonna baseline the car tongiht?

Street Lethal

iTrader: (16)

Hoping my cousin has the calipers installed for me by the time I get home, cuz the amount of time it'll take me to swap it over myself (replacing both of them, not just the one), I might not make it to tech inspection in time. Worst case scenario, I'll run the LS1, or I'll just get Paul and Shawn's Grand National's on video....

hey did u get my pm about what i found out about the timming issue

Street Lethal

iTrader: (16)

No I actually didn't. Something has been up with this site for the last couple of days, not getting my PM's, and I can't run a search (no matter what I search for it says not found, even if I search for something so basic)....

daves12secV6

iTrader: (3)

well remeber how i had disconected the mat sensor from the stock ecm and connected it to the ms.
the stock ecm was seeing -40* air temps
^^^ caused full timming advance under wot thats were my severe pinging and detonation came in,
so instead of say 16* if i read the timing tables right i was getting something like 36* of timing
deff way to much for a boosted motor on pumpgas,even had i goten 110 racegas instead it still would have pinged to hell.

i need to do a compression test, and a leakdown test on the motor now to make sure i didnt break/crack and of the pistons before the next time out

firstfirebird

iTrader: (3)

Better check your rod bearings...

The rod knock is what I was referring to. It just dawned on me that the last time I started it, it was running like crap, probably because the KS was retarding the timing so much, lol. I should disconnect the KS and go to the track and see what happens. (really shouldn't since I already promised the motor to somebody and it need to be rebuildable).

2.8RS

iTrader: (5)

Indeed is does.

daves12secV6

iTrader: (3)

rod bearings are fine, i didnt let it ping/detonate long enough to do any damage,infact after my last attempt at a run i even beat on it in the pits for a bit before loading the car back on the trailer

firstfirebird

iTrader: (3)

It doesn't tke much, you know what my bearings looked like after my first startup following the install. I never even heard the detonation and it didn't occur to me until Crossfire said it was detonation that cause the bearing failure. After replacing the bearing, got it again and there were these little pits on the bearing surface (different bearing tis time). I suppose it doesn't matter as much to you since this a JY motor, just would hate for something bad to happen, like your turbo turning into a "salad shooter" processing metal flakes (or worse having metal go through it's bearings).

Small update;

Some more weight is being removed from the vehicle....

Helping one of my friend's finish up his '95 GSX Eclipse, and when I mentioned to my cousin Gaspar, just in passing, how I was seriously contemplating a manual transmission (I liked the feel better for the street), about 12:00 this afternoon I get a call from him telling me it's done. I'm like, "what's done?", he reiterated, it's done. So "BTA" now has a 5-speed. Kindly hold off on the "it'll break" comments LOL, as we know they're (tranny & rear) are weak, and a much stronger tranny and rear will be installed by the time we hit the track.

Will post pics very soon....

Street Lethal

daves12secV6

iTrader: (3)

5 speed + twins of the size u have = monster lag.
i was making suggestions on parts based around an auto/w stall those hotsides are a lil large for an 5speed setup

Street Lethal

iTrader: (16)

I disagree. I would never of installed the manual transmission had I thought my cousin would experience the lag that your referring to. I can have those turbo's installed for him by next week if he let's me, and I guarantee he'll launch, and stay, right next to you throughout the entire sixty foot, and pull you, despite your auto w/4000 stall setup (especially from a roll)....

There's much more to it than just basing his build on their hotside's, which really isn't as big as people suggest. His car will launch pretty damn well WITHOUT the turbo's, and even if there is lag, we're talking fractions of a second here. I don't believe that Rob is out to set any world records, but I will guarantee that the lag will not be as bad as your suggesting....

When both cars are finished, I want to see them put against each other. This would put an end to all of this speculation....

daves12secV6

iTrader: (3)

those hotsides are big,they maybe t3 housings but they have t4 wheels installed
a single t3 .63 with a stage 3 wheel wont spool till 3,000 on a 3.1
going to a t3 .8x will only make it lag about another 2-400 rpms but thats with a stage3 t3 wheel.

the t4/ptrim wheel is much heavier and larger

firstfirebird

iTrader: (3)

Dave's right. The .8x A/R turbines are going to spool slow on one bank of cyls. I think his is even going to spool slow with the .63 (advertised, remember) turbines. My car starts boost in the low 2k's RPM. Now if you half the heat and gas...

Street Lethal

iTrader: (16)

Well, I'm not going to take sides here, as this build is getting done no matter what. If the worked V6 engine (not the stock 3.1 everybody keeps assuming I'll be running when I'm done lol) doesn't spool the turbo's, I'll obviously step up to a twin turbo charged 350, of course....

HOWEVER, being that I know what my cousin's car's are capable of running (as I watch him and his buddies going at it every other Saturday @ e-Town), I think it's best that until people run the numbers that "they" claim would get you there, to not state if this build will work out or not....

I can appreciate criticism, that's what this thread is for LOL, but I don't doubt my cousin's ability. Everything written on these threads are always based on speculation and theory, but nobody proves their theories, it's always somebody else's build going wrong, so a manual won't work because so and so couldn't get it to spool....

All I can say is, the 5-Speed swap came out flawless, and I'm extremely happy with it, and my cousin measured both turbo's in their entireity, and I trust him and his buddy Joe when they say there won't be a problem. Joe blasts his manual TT Supra into the tens without breaking a sweat, and even he feels the turbo's aren't as large as you guys believe (basing this on the V6 engine that's going in, not the stocker)....

Guess we'll see soon enough though....
