I'm gonna make a T-Bird :jump:

I just realized how f'n easy it is to make a t-bird. There are at least two thundercoupes i know of in the yard last time i was there. And since i already have new bearings in the center section, why rebalance it with an old wheel and then have it rebalanced cause i want a bigger one.............

Simple solution, rip one off at the yard and pay less than 10 bucks lol. So now the build is getting beefier. So lets say i do spend teh winter making a monster in the garage. I'm trying to get a chipped ECU from someone.........

so this would be badass. Could an LX block with stock internals actually take 12-14 psi? I highly doubt it would be lets just say i have more fun with this now.

Also with a t-bird, the compressor housing being bigger would that give me more boost with the same exhaust spool or is it going to take longer to spool with a bigger compressor. Sorry i'm still kinda turbo for dummies on this.

its going to be similar to the stock turbo except it will pull closer to redline. It will still spool early and everything.

I dont doubt the LX block can take it as long as everythings in working order.

Dont even think about upping your boost or cfm unless you sort through the ignition and fuel systems.

Theres a lot of debate about just what the T-bird is. Weather it can realy be considered an upgrade.

Sadly the only GT I have managed to find for sale in the city the last 3 or 4 years I have been looking just went up in flames on the dealer lot yesterday.

Atleast It didnt happen after I bought it lol.

the tbird is an upgrade.....how much of an upgrade is the debatable part. Seems like the tbird should have been the stock turbo on this car to begin with.

I consider it an upgrade

I steadily pulled on a stocker probe @ 16psi when I was pushing 12psi with a nasty boost leak; I also outweighed the probe driver by 180lbs.

Yes it is an upgrade ALOT of people dont think so.....

well the lx motor will take it as longas you dont get ridiculous and start cranking the boost up with no fuel.
My red probe currently have complete lx motor in it, with know sensor and a t3/t4e 60-1 turbo and fcon at 16psi. its works great and pull great. though im still on 460cc injectors. but lx motor is strong. like i said before its hold my 125 shot nitrous and 113 shot for over 8 month, over 22 bottle fillup. and still runs great.

Nope... come back when you have a turbo that flows 2x the CFM's. Thats an upgrade.

Id still ike to see some dyno proof of this "upgrade", and not butt dyno testimonials. Just because it feels like its pulling to redline, that doesnt mean it is.

completely stock form, maybe, anything done to the engine, and I have to think that the tiny little hotside chokes it out!!
A 3" downpipe from the turbo definatly helps, but I still think it does max out.

now, all that said, I still think its an upgrade, as it does push move volume. A huge upgrade...no...

From Dictionary.com, there second definition of upgrade: an increase or improvement: an upgrade in the year's profit forecast.

Being a larger wheel and housing would be an increase in size and improvement in flow. The only ones arguing that it's not an upgrade are the "go T3 or go home" folks like yourself. I don't have exact measurements on me right now, but stock inlet and outlet is about 1.5"; tbird inlet and outlet are 2"; inducer tip on the compressor wheel is just less than 7% larger (39mm/42mm) providing 17% more flow 300/361CFM).

Stocker flows ~8.5 m3/min (300 CFM); 2.6Pr
TBird flows ~10.25 m3/min (361 CFM); 1.8Pr

Now these are the very limits to takes these compressor wheels would mostly include fragging if these numbers were sustained over a period of time. As you can also see, the Tbird flows 17% more air at roughly 2/3 the Pr of the stocker. So tell me again, why isn't this an upgrade?

Are you suggesting no one has ever dyno'd a T-Bird?

I know that there was one a few dyno meets ago. He bought the car with the T-Bird already in it. Definitely held the power as the RPM went up. If I remembered the guy's name after the 2-3 years it's been, I would look up the plot for you.

but thats all change when you add the stock housing, which will choke the exhaust wheel making the wheel inefficient, i have rode in a tbird with the original t3-ihi exhaust housing and they made a huge different. maybe 30hp different in feel alone.

nope, been in a ft2 truck, with a ihi (from a t-bird), and mine, which is a hybrid, and there is ZERO differene in feel. Maybe a bit more from mine, but I also have engine work done.

Now, if I still had the POS cast downpipe on there, yea it would definatly choke it out.

yeh there is, i probably still have 3 tbird turbo/hybrid just laying aroung. i have try it. with or without bogget exhaust. definely a lot better with aftermarket /custom exhaust o2 housing. with stock o2 housing sucks

Why dont you search to find your answers OP? Everything you post about has been beaten to death 946 times around here. And no, a tbird with an ECU chip isnt "a badass monster" :lol:

compared to a stock LX i'd say it would be a wicked combo. Its a GT ecu with a probinator chip in it. Now i know the chip does a few things like correct fuel map and things like that but after thinking about it if i added bigger injectors than the GT has, not 330's but something larger since i may need it what exactly would i need to do.....lets just say 12 psi. Maybe not 15 cause i dont' want to kill this thing. But would i still need an FCU for the added boost or would the probinator account for that?

My buddy does extremely good welding so i'm going to have him make a flange and have him probably make me a down pipe. I need to find a flange that has the 5 bolt patter unless someone on here has a link to one. I want to keep PS but this summer had some pretty hot 90's days and it didn't really bother me that much. And after i boost this bastard i really don't GAF about the AC so i'll probably just take i out or at least take out the lines and such so i get more room. I'm also picking up a GT head if i can find one thsi weekend and his uncle has a machine shop that would port and polish it. I'm also changing the springs to some new ones unless i should get some that are stiffer. But since i'm not messing with the cam i'm sure i dont' need stiffer springs.

i want to install my tbird so bad so i can see for myself how it feels. Just waiting on getting the inlet adapter made because i dont have much free time working 50 hours a week

.

you shouldnt have any problems boosting an lx motor. I ran 10-11 pounds on it for a year and a half and the pistons were in great shape. No sign of detonation at all. The only think that happened was i blew the headgasket.

everything stock GT swapped over. Probinator chipped ecu was the only mod i had. As fpr the tbird im not sure. If it does flow more depending on who you ask, then you may want a walboro 190 and maybe some slightly bigger injectors. if you can afford it i would just buy a wideband and fine tune it.

and wasnt there someone who ran a high 13 sec 1/4 mile pass with a tbird on here? A high 13 sec. car is plenty fast enough for me or else its just going to get me in trouble and most likely become less reliable.

Yes.
