Aww man I got $20 too. can i go in on this project with you 50-50

 

As of now I am researching another way to get my hands on a set of turbos. I'm starting to not like the ebay ones
For those who can answer this...
What size A/R would you guys go with. I have done calculations and came to a conclusion that the .42A/R is just too small.
I was planning on going with a .60A/R... I know there are alot of other things that depend on this but i still ask the question

 

You said you want 5 psi only....you have your own answer

 

69427 and c4cruiser both have good points.

Cory, you said its not your daily driver and that will be your daily driver once it gets insured
Now you don't like the ebay turbos,and you name ".42A/R" and ".60A/R"
Well i will give you MY ADVICE ...

With 125k your engine is tired,thats what i think.-
If you know that you can mess it up,go for it !
But if you want power,build a N/A engine,build a healthy 350,355 or maybe a 383
if you have the funds you can always get a 421,im sure that will be pretty quick
Much more than a 205 hp turbo engine that makes 300 hp ...that makes no sense
My choice would be N/A...all the way,then...if you have forged pistons and rods
Supercharge it,you can do 600-800hp depending on what are you supercharging...
but that takes a lot of $ $ $ $

and btw ...a few posts above i read that you asked if going with .42A/R or .60A/R
No offense but that statement made me watch your profile and makes me think you called a friend or something.....



Cory,you are still in high school,i really hope you have the funds to do all of this
we'll see down the road !
Best of wishes ! and im sure if you build a healthy N/A it will be cheaper
and way powerful ! i always see SC and Turbo as add-ons
Imagine your impeller breaks....you'll be making 205 hp again !!!!

 

 

5psi would be a horrible return on investment... lots better options to make that much power for the money

 

i am pretty certain 84's only had d36's..

 

fyi -if you break an impeller you are going to be making any horsepower.. ebay turbos are crap. end of story. you are going to want at least some t3/t4's to be able to do what you want and still be able to turn up the wick when you get a decent engine. its going to be way harder than i think you are anticipating..

I kind of lost track of this one for a bit.

I had a good basis in turning a wrench and doing bolt on installs, engine R&I, basic tuning (piggy back), etc. Met a guy through the car clubs that had his own small shop, excellent welder! great fabricator. He asked me to come work with him and I gained experience and learned some fab skills, and a lot more about turbos than I knew before.

The key is research and practice. Garret has some good info online including how to run through the calculations to see if a turbo is properly sized for you and not going to surge or be too small for your app. There are some good books out on turbo charging as well. The old standby for a lot is Maximum Boost by Corky Bells, I can't think of some of the other ones off the top of my head.

I disagree with a previous posted that 5 psi isn't worth it. It's a good starting point, to start tuning from. You can't crank up the boost to insane levels until you build up other parts, and a low boost level gets you more power and your feet wet into tuning.

One more bit of advice. Look at what budget you think you have an increase it by probably 50% The little parts add up surprisingly quickly, and if this is a daily driver I would plan enough extra money to at least drop in a cheap replacement engine should something happen during tuning.

 

 

Why all the negativity? There's been lots of guys who have done turbos, and I agree 5 psi is a great place to start. I'd even go with the turbos you started with, not the best, but at the cost you'll gain alot of experience and won't lose to much $$$ if it does go TU.

 

Checkout JoBy's '84 Corvette

He's run both a supercharger and a turbo

Well guys just a little update I took some of your advice and decided to put off the turbos for a little while until I have a stronger engine, tranny, and rear end. So as of now I am doing a 5.3L "LS1" Engine swap and already have most of the parts to do the build

Thanks for all the advice guys

I hope it gets turbo(s) after it's in there!

 

84 engines have forged internals?

Got the link? I am lazy....lol

 

they have forged pistons...

 

I plan on it
