looks nice...keep the good work up bro.....how much boost u running? what u got for a turbo?
only 5lb... my clutch is sooo shot the car barely moves... so i cant do anything until i do that first, then more tuning... then more boost. Its a Garret T3 .60 .63 off of a turbo svo mustang

Looks like you got a hole for a bov.But know bov?
i have a 1g dsm bov in it now... at 5psi and an open dp it isnt loud... yet

Mad prop's.I know how much work it is.And $
kew....but you didn't pay alot for that welding job did you ?
looking good.... although a drop wouldn't hurt... good luck with the clutch and tuning.
That intercooler looks just like mine and about the same size. Im going in the morning to pick up the B20 finally from the machine shop so hopefully it will be in soon. The shitty thing is i don't have crap for time now because of school work but im excited just to get it back from the shop after 2 months. Good work hopefully you get the clutch taken care of so you can run it a little harder.
Nice work, Jason! Tell us about your engine management, and how the car runs so far. Any pre-detonation problems?
"Feed their greed with your need for speed"
mad props from me too, yo. What is your manifold contructed of? Overall, it looks cool, but if I could offer a couple tips for next time they would be coupling the non adjacent cylinders together results in slightly better scavenging if you don't have a 4-1 collector, and also, a higher heat setting on the welder (or a lower wire speed) would have resulted in a little cleaner appearance. And I highly recommend you wrap your power steering line with that thermo tec heat reflective shit. Very cool though, it's nice to see another turbo 3g, too bad you aren't in cali though, so I could smoke yo ass! ha ha, just playin
p.s. im running 9lbs now (still with sketchy tuning though)
hey when you mash on it at night and then look at your manifold, is it glowing? I had to make a heat shield for my shit
Pre detonation? Pre detonation isn't a problem, it's actual detonation!Originally Posted by Robs89LXi
Nice work, Jason
Detonation is a good thing. It's what makes our engines run. Pre-detonation is a bad thing, and is more common with the higher heat produced in boosted engines.
"Feed their greed with your need for speed"
very nice setup. mad props.
i don't know why you want detonation. it is not good for engines at all.
Alex.
good job, i'm very jealous.
3geez for life.
rob i think your spearco core might be bigger... idk. Yeah i wanna do a drop etc but soo far id rather go fast then work on suspension... suspension costs $$$$ that i dont have but it will get done sooner or later. yeah you are right accordtheory, those top welds i should have gotten hotter with... the bottom ones i did so it came out ok, no cracks etc. Yeah the mani is better than a log but not as good as say... a ramhead design, its just a 4 into 1 basically. Also the mani or anything underhood really doesnt throw as much heat as i had thought it would, esp being mild steel... The front motor mount and the front beam had to be notched a little bit to get the turbo to fit with a little bit of clearance. Soo far im using an SAFC and 450cc 1g bluetop dsm injectors with a walbro 255lph intank and the msd btm. The pics make the welds look worse than they really are (just trust me) they arent the cleanest but they are damn strong. I need to hook up the MSD BTM tho when i start running over 5 psi... I want to run about 10-11 if i can then maybe more with different managemant and built engine (i have another engine im working on) we will see. It does have a golden eagle adjustable cam gear that i have set to -3 degrees retard, im not sure if thats hurting me or helping me making power with boost, that was from my N/A days... ill tell ya for 5 psi the car has one hell of a top end... The transition from vaccuum to boost is seamless, it spools up around 4k and is a little laggy, but its a .60 .63 with a lengthened wg actuator rod... so honestly i expected it to be worse. When the wastegate rod fell off the first night i took it out it boost creeped to 3psi... with no actuator on it and the wastegate completely open. Heres what i have in the car soo far:
Garrett T3 .60 .63
sillicone couplers with T bolt clamps
Custom Coach Intercooler
owner built (thats me) custom turbo mani, flanges by BMC
2.5" Charge pipes
Apexi SAFC
450cc 1g dsm bluetop injectors
MSD BTM
Aasco aluminum flywheel (8.5lb i think)
Auto to manual conversion (used to be an auto car)
1g dsm bov
open downpipe
removed a/c and back seat as well as some supporting metal in the hood, stripped trunk.
Bypassed coolant line mods, disabled intake manifold runner switching etc...
Oh yea and Stealthmode performance stainless braided oillines....
Also some other little things like gauges etc

props for putting up another turbo 3g on the street. What did you have to mod to run the intercooler piping, I know there is no room between the bumper and frame.
I'm your local R&D nut. Fabracting, welding, tuning and breaking my stuff so you don't have to.
i had to cut about an inch out of the bottom of the bumper steel beam to get it to fit, and also take out my windshield washer bottle etc to get the pipes to fit. Also i notched the radiator core support so the power steering cooling tube is between the radiator and the intercooler... i moved it back. All this stuff took FOREVER to get to work, lots of cutting and fitting

Detonation is what occurs in internal combustion engines when the spark ignites the air/fuel charge. This explosion is what expands the gas charge to cause increased pressure and thus force the pistons to move. Properly timed detonation is what we want.
Pre-detonation can occur when increased heat causes the air/fuel charge to self-ignite before the spark event (pre-ignition), which leads to pre-detonation of the charge. Because it is not at the proper time in the piston travel event, it can be bad for our engine, and we do not want this.
Due to the increased heat produced by turbocharging, this is a fairly common occurance in boosted engines. Intercooling is certainly one of the ways to help correct this.

holy sleeping beauty batman
damn that is a sleeper right htere
.
Actually, detonation is always a bad thing because it describes uncontrolled, explosive combustion that creates violent shock waves in the combustion chamber and leads to piston damage and blown head gaskets. Proper combustion is a smooth burn of the mixture across the chamber and is different from detonation. Pre-ignition is essentialy what you described above and I have never heard the term pre-detonation used before. For a good description of these processes, check this web site: http://www.hastingsmfg.com/Service%2...reignition.htm

I like it, What gauge was the mild steel?
od2681... it's not really a sleeper if you can see the IC.

LOL. Okay, I stand corrected. I was using the word detonation to describe what I had in mind, which is combustion. Tomatoes, tomatoes.

:comes back with his right hand hurting after jackin off: umm...... i was not doing anything......... oh nice pics dude. Mean ass front mount.
Smooth man! (not the welds) can we not put a carb vac diaphram on the dizzy mounts and sum how have it pull the dizzy into retard position under boost?
