I think you guys are being too optimistic that op can achieve any of this

 

Well the other thing I thought was dropping I'm a 4t45 considering I scrap one in the back yard. Apparently the only the difference of the two was that that the 4t45 was heavy...

 

English. We speak english here.

 

 

Different transmissions. 4t40e is the sunfire cavalier. 4t45e is the grand am. The 3800 had the 4t60 and 4t65 I believe.
And the v8 northstar had the 4t80 transmission which I'm now starting to wonder if that tranny could possibly drop in...

Difference between the 0 and 5 for the last digit ment that the transmission was made for higher torque and horsepower applications.

The first digit meant what speed the tranny was so 4 being a 4 speed.

The new ones are 6t## means that they were a 6 speed auto.

I've looked up this information before but that's about all I know I'm not sure if other torque converters will fit in differently rent trannys I haven't got that far in the research.

 

Oh and forgot the second last digit was used for the size of transmission. 40 being small economical. 80 being the biggest and strongest.

 

Thank you for this golden information you have bestowed upon us.

 

Okay so from what I read the 4t80 is just not worth it... Just way too large apparently it's like an elephant over a 4t65.

So my question is for you guys (I've been looking all day on Google and found 2 spots with torque converts.) Is there any aftermarket high performance torque converters for the 4 speed auto on a sunfire? I found one on import transmissions and general motors torque converts. Both site seems not so legit untill I'm told otherwise. Goals are 400 - 600 bhp (whp unknown) (closer to 400 than 600 cause I just don't thinks its imagable.

I'm getting the engine once built dynoed and tuned at a shop before dropping in. These guys im going to actually built a 2000's grand am with 1400 hp power. (Street and strip) V6 twin turbo. (Not sure what they did but they told me to stop by and check out there build) and apparently they have done a twincharged Saturn before putting out 465whp. So I'm almost onboard with these guys...

 

Why would you ask a question get told by 100% of the members on here then stick with it??

DO NOT TWIN CHARGE!

 

Well I already have the turbo and the supercharger bought... Turbo came off my old cobalt and it never had anything until I hit 4000 rpms which was always a pain is the **** waiting for the lag hitting it, shifting, lag, hitting it, shifting.

That's why I'm going twin...

And no I'm not paying another crazy amount of money on another turbo when I already have one.....

And my question was about torque converts...

And everyone has there own way or idea of building things and everyone else isn't going to understand why or how. But those people still do there build and at they end they all have one thing in common there own unique build.

You guys probably seen or did twincharging I haven't and its something I want to do. I respect the people running turbos out there, I just wanna do the twincharge... If you all really don't like the fact I'm twincharging I just have one thing.

Haters gonna hate.

 

Haters gonna hate? You are expecting to make insane power with garbage you have laying around. Just because you bolt parts on doesn't mean you will make power

 

This is a pointless thread

 

Ya i think you should sell what you have get a nice snail and be happy! How and why would i hate???

 

No its not this is hilarious
Im still trying to figure out if op is a troll

 

I feel like he is a troll since he liked the idea of just running an m62 then went straight back to twincharging

 

I feel like this thread is going in circles....

 

He doesnt understand how horrible tuning a jbody is. Like literally. It has the same processing power as a motorola razr.

 

The threads not going in circles I'm twin charging and that's that.

And yes actually plan is to use the m62.... But when some good funds come in I plan on buying a Whipple or so that the idea.

Question tuning. Would tuning be easier with a standalone system? CBM makes a 2.2 eco stand alone but I heard it was like 2 grand. I checked today it 899$

 

well this thread is def going in circles, we have given you more then enough information to help you get to your goals! sell the **** you have and buy a nice turbo like an S256 or S259, what for damn turbo do you have that spools at 4,000rpms??? good luck gettting a whipple under the hood to because thats not gonna happen either. so til then ill stay posted on this thread but i will warn you now, if no no, when your **** doesnt work dont expect to come back on here with your problems and every body be all happy go lucky and wanting to help you.

 

Lol. He is beyond help. Custom **** is easy right? Thats why everyone does it right? Wrong.

 

dude what i have realized here is i think this guys gonna be bringing the twin charge back from the past hahaha. he will be so dissapointed and ill be sitting here waiting with my bucket of popcorn for when he comes crawling back for help lol

 

everyone is saying that you need to research because you have an amateur idea of what makes power. just because your installing a turbo that MIGHT make 300 hp all out in a 2.2 and a supercharger that MIGHT make 270 hp in a 2.2, you wont make 400 hp out of it. youll probably make an average of those 2 at best if not less.

it costs power to turn a blower just like it does your ac compressor, so it eats away at your power output. thats why you can get away with smaller injectors on a turbo, because the parasitic loss of a restricted exhaust flow is much less than spinning a blower. the m62 and the k04 flow a similar amount of air up top, but 1 beats the other in power output

and also, boost is a measure of restriction. it is not a measure of power. you can take a head that doesnt flow for **** and put a baby turbo on it and make 40 psi of boost and literally no power. thats why we look at the thread and laugh at 90 psi = mad power bro!

and for the love of god, please dont assume you factor in atmospheric for boost pressure. if that were the case, anything under 14.5 psi would be negative boost. boost is anything past atmospheric.

 

Twin charging does work well. You just have to know how.

 

i know it works good but when it comes to a 4cyl its just much easier to run a turbo lol

 

Okay I really don't get this entire tuning issue going here so I'll bring up the question again..... hp tuners has a program that actually tunes the pcm, ecm what ever for a 2.2 they have the program, so couldn't be that complicated.

And ad the average of the two together that's what I'll get at best. ???? Wtf????

270 supered and 300 turboed.... So it would be like 285... That doesn't make sense. The I've never seen a twincharged that was under 350hp

Okay so there's 2 of not fully against twincharging you just rather me take the simpleton route with everyone else slap the dang turbo on and go?

If I was gonna go turbo I would've slapped it on a year ago and got a crapflash at GM.

I'm a blast from the past Kool. Oh well it happens. You guys all wanna do your thing and type fine, I wanna do mine.

And I still don't understand if the super is running 25 psi and the turbos running at 25 where's the restriction? There both running 25 psi so when I hit 25 low end the supers going high end I hit 25 from the turbo...

Although it doesn't seem effective at that point cause then you'd only need to run a super. Idk....

Which is the reason why I'm here learning.

And custom work to me is nothing uncle owns a shop, he's built s
Custom things before... He's older though and doesn't know a thing about these "electric cars"
