Turbo advice

[Rouseman]

Hey all. Before i start keep in mind ive always had N/A cars and my experience stops there as far as forced induction goes. However ive been offered a stock turbo from a dodge shadow, for free. ive looked it over and its in good shape. Iam interested in charging my alero but i have some questions.

ive herd i need bigger injectors, is this true?

will i have to have it tuned before i can do anything?

do they make a turbo manifold for the la1?

And of corse if anyone has attempted this any input would be great.

if you are going turbo definitely hit up BJ, but as far as bigger injectors and a tune yes they are a MUST!

will i have to have it tuned before i can do anything? Not necessarily, but it would be the first thing I do(after getting the turbo and everything on)

do they make a turbo manifold for the la1? Nope, you have to get a custom one made.

And of corse if anyone has attempted this any input would be great. Blackjack has, I know a few others. You can also go to grandamgt.com where others have turboed there car to.

Be sure to do plenty of research, cause turbo is more than just injectors and tuning.

Turbod la1 is nothing bolt on. And b prepared to pay up...my friend Torre turboed his la1 ga last winter n had invested like 8-10k. He dynod at 301whp n 360tq w maxed out injectors n a failing fuel pump. He will get redynod this summer. U need custom manifold n everything. Research research research!

Can't emphasize this enough!

I dont know what kind of engine the shadow has - but a turbo must be selected strictly accourding to your engine and manifolds your running.
a big turbo may sound good, but wont bring u anything, unless the "diagram" tells so.

What I mean with diagram?

For a first overview see this CarCraft article (http://www.carcraft.com/techarticles/ccrp_0907_turbocharged_engine_guide/index.html)

thanks for the advice everyone, ill get some specifics on the shadow turbo...i think its a mitsubishi turbo?

[guiguilandry]

the shadow turbo is wayyyy too small for the la1 because there is simply not enough cfm that he can push..... sorry to tell you that but it is true... it would be great for a ld9 2,4l or l61 2,2l but too small for the la1 3,4l...

[[ion] C2]

I wouldn't use the Shadow turbo on any car.. put it on a lawnmower

could twin turbo...just use it to spool a big beastie :coolio:

but I'm sure that's way more involved than he wants to get

Hopefully he did A LOT more than just a turbo setup, because if that is what it cost him to do just the turbo setup he got RIPPED HARD!!!

A turbo setup can be had easily for 2-3k or less if you shop around do your research on buying parts.

I know its small, but is it really to small to do anything whatsoever? iam not expecting huge gains and 10 second times:lol: , iam just looking to get started.

[Rouseman]

anyone?

[guiguilandry]

If the turbo is too small it will restrict the exhaust flow of the engine and will cause overspinning and become too hot in the high rpm ( I think that this turbo don't have coolant going through)... this will make it overheat and finally after a period of time it will seaze or get destructed.. did you ever see a turbo housing getting redhot to the point of melting things aroung in the engine bay... lol I did... it was funny to look at the melted brake master cylinder dripping on the tranny.. and that's not a joke....

[BlackJack]

Here's the simple breakdown on that small turbo. You got way too much exhaust flow from 6 cylinders combined pushing through that little bitty turbo. Imagine plugging a 110 volt electrical appliance into a 240 volt outlet. That's about the simplest way to put it.

If you are dead set on putting "that" turbo under your hood, it can only be done one of two ways. find another one and do one per exhaust bank for a matched twin, or else use that one to spool a big one, and you better have a really huge wastegate before the little turbo.

Either way, you end up with two turbos. That one by itself won't cut it. It's designed for a 4 cylinder stock type engine, and when you push 6 cyls worth of exhaust through it, you're going to kill the poor thing in short time.

Thanks for the explanation, makes more sense to me now, iam going to look into this more. Twin turbo la1 sounds like a blast tho.:D

Well, there is the way like the old Saab V6. Just run the turbo off of 3 cylinders, Asymmetrically.

I like this logic! Not realistic though, there really isn't room for a turbo on the front manifold.

you could fit both of them where the battery is at if they are smaller, with some fine fitment of course.....

[Lucalare]

Good call, too bad I don't have the money to buy two turbos or use a twin turbo car as a DD.

[BlackJack]

Not sure on the whole fitment issue, but I do know I am toying with the idea of stripping down an Alero to the barest of street-legal, complete with a power steering delete and manual steering rack replacement, along with relocating the coolant overflow and ditching the cruise control module to see what kind of room is free'd up on the passenger side of the bay. This might give me some options for an under-hood TT setup. We'll see. It's more probable to add a rear-mount on top of the setup I already have though.
