Unless you are dead set on using a turbo, I think you should follow sofakingdom's advice.

Yep, he's right for the most part, but putting a little harsh I think.

You CAN do a RMT setup relatively inexpensive and quick while not falling apart, but honestly you have to really know your stuff to get those three together.

Can you weld or have access to a friend who can for you? That'll help immensly.
Do you have all the money you'll need within the time period you have? Take that number and double it. Will you have that? Do you know exactly how turbo system's work, in full?

The turbo motor you're talking about building is roughly exactly the one that's in my car (STILL waiting for the turbo setup to be installed after over a year, btw. Deadline's make things very hard, trust me.) It'll handle boost fine, how much depends on more factors than I know. 10 psi should be no problem, if I have to throw out a quick number for you.

If you have yet to build an engine at all, yes it will obviously be easier to do a N/A 383, since that's not more difficult than building a 350 for boost. You have to build it either way, but the turbo system is a whole additional system to build.
Honestly, if you have mild dynamic compression in your engine now, you should be able to take him by only adding the turbo system and tuning. If your dynamic compression is pretty high, then you should probably build another engine to do it right.

Like Sofaking said, a Vortec 383 will be relatively inexpensive, and powerful if you match up the combo properly, tons of people on here have done just that.

In short- It really depends on how much you know and how efficiently you can get it all done. If all you want to do is beat him, build an engine and suspension and be done with it.
If you want a more involved project that will beat him while kicking you in the rear every time your turbo goes ssssssSSSSSSSS once it's done and you have the ability to do it, than do a RMT setup.

Budget? Deadline? Engine knowledge? Turbo knowledge?

RMT...TT? Decisions Decisions.

This is getting on my nerves..i am putting so much time and effort into figuring out the pros and cons. I can get anything welded that my little heart so desires. I am debating flippin my headers upside down and going twin. The remote wont function as well as if it were up in the engine bay from what i read. Plus all this power from what i have read my rearend wont be able to handle. I drive an 83 that originally had a V-6. It will have a locker when this takes place. 10 bolts are only suppose to be able to go up to 400hp. I am just looking for all the input i can get on this before i start into it.

Sounds like you are short on patient. Re-read what Steven89Iroc said about doubling the time & money estimate. I don't think you will be doing twins by the sounds of it. It is rather straight forward. The Pro is that you would have a somewhat quick car. The Cons are that it could be more unreliable and requires some work/effort/learning on your part.

Upside down mild steel is quick and dirty, but yeah it works. How long do you want them to last? If you don't launch it hard then the rear end will handle. Most of the people that I know that are patients limited tend to launch hard and beat something harder when it don't meet their expectations. Be careful of that......it breaks a lot of parts.

And then double that a couple of times and then you’ll be getting close to what some people have gotten themselves into…

I have visions....

So ithink a single RMT will do me in quite well for what i want. I dont needs gobs and gobs of power so this will give me a streetable car. I can turn the boost down rather low for the daily driving and then up it for the quik stoplight. This RMT will also work on a budget.....somewhat. So i am set on a single. Just to rebuild the 350 to handle it is my goal now. So now i need info on the oiling system for a RMT. I have been told to have some sort of pump to continue to cool the turbos' oil after i shut the vehicle down, and also so the oil doesnt drain out the bearing.

I will invest in a good BB turbo that will last me. Now i need specs on what i should be getting because there are so many diffrent turbo's out there. maybe like a .60 trim with a 1. compressor? These are my last questions, i promise.

Actually, they won't be the last questions, I promise.

Now that you've decided on a RMT, read through this thread thoroughly.
https://www.thirdgen.org/techbb2/sho...hreadid=238864

You don't need a BB turbo for reliability, but it will help with spool. I wouldn't worry so much about spool with that setup, you'll still have a torquey L98 that can't get traction as it is, lower compression doesn't take away much.
Providing you set it up correctly, a non-BB turbo will last a very long time, and it will cost half as much. If you have the money though, yes BB's are overall better to a degree.

Now, what's your hp goal? If you build the L98 like mine, it should handle 500hp no problem. I'd say get something along the lines of this, give or take (BTW, that picture isn't that turbo).

Go with Phoenix Turbo, too. I've never heard anything bad about them (even when they were cheapturbo), and I bought my Talon's turbo from them as well. Good prices, good service, good turbos (real, brand new Garretts).
