Well, if you didn't know, I've had some studdering problems with my car since the turbo. I have always thought that it was not because of the turbo kit, but rather something wrong with my car before the turbo was ever on. Well, today I found out I was right!
Welll, today I swapped out my Mutiny Bored TB with a stick TB. I even used my IAC motor and TPA sensor from MY Bored TB and put them on the stock TB. The cars runs great now! No studdered whatsoever! I have no idea whya bored TB would do this!!!
The reason I never figured out it had something to do with my TB was because I had just gotten the TB right before I purchased my turbo kit. I still am stumped to know why its suddenly working fine now???
I think my EGR valve has crapped out though. I had about 2mm worth of soot un the backside of the TB butterfly. I think my TPS sensor might aslo be screwed up, not sure. I'm going to test them as soon as I can get my hands on an ohmmeter.

Oh, I figured out how I blew my motor up fellas
TO MUCH BOOST!
Be very very careful when adjusting the screw on the deltagate wastegate, don't turn it in too far. I did that this last summer and it smoked my motor, basically by boosting to infinity. I guess there is some point where you can't adjust any more and the spring doesn't open at all and just keeps spooling up!
i found that out tonight whike trying to boost a little higher by screwing in the adjsutment screw. luckily, I kept my eye onmy boost gauge and saw it spike to about 1.5bars (21psi) I immediatly let off and unscred the adjustment screw on the wastegate.
Be careful, keep an eye on it.
This past summer I tightened the screw all the way down right before a street race, just thinking it would max out around 7-7.5psi, well, I'm guessing it didn't, and kept spooling until it blew 2 of my pistons.
I always wondered how I was beating a low 13 sec MR2 I bet I was boosting 20psi + that night !
hehe..
Anyways, be careful, keep your eyes on the gauges!

Ya'know, 90% of the time, it's only one of two things....too much boost or too little fuel!

I'm glad you know why it happened. I wonder how much you were boosting that night? 20-25 psi! > Wow! That woulda been something to see how fast you were going. You know you musta been lean as hell and boosting that much....wow.

Glad you got your stuff remedied!

yeah, I'm betting I was bosoting htat much easy, maybe even more.
I didn't even get a chance to see my boost gauge (when your racing you tend to not look at things, specially when its on a small country road).
All this time I never figured out why I was spanking that 13sec MR2 so bad until now
Oh well, at least I know know!

The main thing is fuel...lol
remeber since the t3 t4 is a bigger turbo and creates more air...
thust the need for more fuel...i gotta keep telling you guys ..more air=more fuel =)

p.s sound good jason?

That they know. Now if they could just keep from feeding their once stock pistons ungodly boost accidently/just to see what will happen everything would be okay.

it was a joke ..jason should know =)

Good man Locke...

Heh...Locke said that cause he knows I'm always giving everyone crap about having enough fuel!

It doesn't matter to me as long as you guys know what's up!

Honestly, i don't see how the t3 t4 puts out any more air. 10 lbs. of boost in the manifold is 10 lbs. of boost. Temperature wise is where the two turbo's would make a difference...but intercoolers generally correct for that issue. the other differences obviously would be how fast it can put 10 lbs. of pressure in the manifold. 16g would do it alot faster, cus it spools faster, but it wouldn't be able to keep the higher amounts of boost in the manifold at high rpms, since it doesn't flow as much air. the way i see it, there is lbs. of force behind the intake valves waiting to get in there right before they open. 10 lbs. is 10 lbs.

I have to strongly disagree with you Griz...

...are you saying that if Eclipse one has a T-25 and eclipse #2 has a 20g and theyre both boosting 10psi at the same time, that they're going to have equal power and have equal needs for fuel?

Nope, that's why everyone upgrades the fuel stuff when they upgrade the turbo. That's why the first gens have close to the same power as the second gens with LESS stock boost. (10psi (1g) vs. 14.5 psi(2g)) Each turbo pumps out different rates of CFM's. 5 psi in one turbo is much different that 5 psi in antoher.

Interesting subject there. does 10psi=10psi regardless of turbo. I guess the question should be can different turbos force different cfms of air into an engine at a set pressure. Will t2small flow 300cfm at 10lbs and 16G flow 350cfm at 10lbs of boost? Damn if I know for sure but I'm guessing a bigger compressor wheel (I know there is a compressor side and another side but don't get me started lying trying to be technical)will suck in more volume at a given pressure just by the wheel grabbing more air each go round. Damn if I know what effect the housing size has. And which flows more T3/4 or 16G? Hell there's how many 16G's: big 16G, super 16G, regular 16G and probably who know how many more. The T3/4 is a hybrid to begin with and can be configured to damn near any flow. Not to mention options like clipped wheels ect.

Thou art not temp thee into boost!

ok..here is what i am saying...not all turbos are created equal...everyone has different characteristics....for example...t3/t4...top end out the ass...cus it has a higher CFM, 16g...spools faster, excellent street turbo, but high boost levels say...25 lbs, it will die off in the upper RPMS. T25: pile of shit! just witnessed my friends blown t25 on his GST...not a pretty site.

Another difference in turbo's is the temperature of the air that they put out, higher the CFM, generally, the lower the temperature of air at that boost level...for instance, a t25 at 10 PSI will be way hotter than a 16g at 10 PSI..that is how a 16g makes more power.

And yet another difference is spooling characteristics...but i think we all know basically about those..

This is what i mean though... 10 PSI in your intake manifold at a given RPM and at the same air temperature, will make the same amount of power...regardless of what turbo it is... where different turbo's make different HP levels, is if the boost falls off, or if at a higher RPM, the air gets heated more by the turbo, and not cooled off enough by the intercooler...that is how different turbos can make different HP levels at the same PSI. so...i guess i am contradicting what i am saying earlier...but the way i see it, if you have an intercooler that can cool your intake charge to low temps...and a turbo that can hold the same amount of boost to redline...then it shouldn't make too much of a difference what turbo you are running...it's in the low end for spooling is where you should be concerned.
