After doing some research & seeing the kind of torque a turbo can produce I believe 600 hp or so will be plenty.

I would shoot for as high as you realistically can do and afford - Jim Woods does excellent work and I know the Merc is heavy but the 408W needs to have double the power it is making now because I am fully used to it and it almost seems slow TO ME ...

I am saving $ for the future day when I will have Woody build me a Dart blocked SBF complete with a ProCharger S/C on it -  the fat-assed Merc needs 4 digits of HP (1000+)

I've got to get some help before I shoot for anything. I even joined Theturboforums & found alot of info but only some of it makes any sense. Looks like reading material is all I'm going to get over there as it appears I've been snubbed, No luck at the Corral either lol.

I was hoping he would pop back in but he's probably busy with a project of his own. I appreciate you trying to help Merc.

I am just trying to figure out what will be needed for my goals so I can go into this with a plan. I will still have to sell my n/a stuff off to get the turbo project going.

I would like to start out with minimal boost so I can learn as I go w/o melting my junk down. I will also be checking out what fi parts will run used. After reading up a bit, The carb route might be a little tougher to tune than I thought it would be. I'm not opposed to either yet but don't have enough info to make a decision...

Blowthru carbs are only a tuning headache when you are either too stubborn or too cheap to just buy a good one from a reputable custom carb builder.  I recommend Kevin at CSU, but there are other good ones too..

EFI makes turbo - boost - seamless.  It really seems to help the boost come in softly and the drive-ability is noticeably better.  But its at a substantial cost increase.

If this is mostly a street driven car, and not a mostly track car - keep the turbo on the small side A/R wise.  If you are willing to run "twins", they can be very beneficial to keeping the car responsive down low.  Most people that gripe about "turbo lag" fit into one of two categories. 1. They are running to large of a turbo - that makes great power up top, but is sized for racing; or 2. They don't know how to tune a turbo car.

What is your budget here Farmer?  Are you going to fab your own kit or do you just want to buy one?

My budget will be small lol. I'm going to try & do it with the sale of my cam,lifters & headers. If I can't find something used I'll try to fab something up. I have some thick shorty's but they are only 1 5/8" & might be too small for the AFR's.

The car will see more time on the street than it will the track for sure. I have a 20 mile drive just to get to the nearest town with any cruise action & it would be great to make this drive with no worries.

Looks like the carb will be pretty high but I might be able to make a deal with Quick Fuel & trade my Q750 in for an E85 bt 750. I will need a different regulator & pump as well but those can be traded back also.

Thanks, I was about to bail on the turbo idea if I couldn't find some help.

Ask Mighty Mouse but IIRC 1-5/8" headers would probably be enough for your turbo idea ...

Talked to Lil John & he thought 1 5/8 primary's might limit things when turned up. He also said a Borg Warner s400 is what I should consider using.

How is a turbo of that size going to act on the street? I was told it will support up to 1100 hp on my engine. I want to start out at 5psi until I know what I'm doing & want to be sure I can do this.

If you are on a tight budget, there is nothing wrong with using a 1 5/8" header turned around to start your hot side.  Cut the ends off and weld on V-bands.  You will thank me later.

The S400 series is/are T6 Turbos.  The most popular of that series is the S475 and the S480.  Both will drive an engine like yours into the bottom 9's and high 8's respectively.

They are UBER heavy and require major bracing.  Do not rely on the headers to hold it up like the T4s out there.

I put together a S400 series build a couple years back.  I was careful how I purchased every part.  I did most of the work myself, and my brother helped with the rest.  A conservative estimate - I had $3500 in it when I was said and done.

You could probably do a master power 76mm T4 turbo with chinese wastegate, blowoff and intercooler for around $2k - $2500 if you do most of the work yourself and flip some shorties.

I thought the s400 sounded like more than I needed. Can parts be bought to mate to my shorties or will I have to fab the whole setup? Also, Is the Masterpower turbo a good enough piece to last awhile?

What kind of power could I expect from the MP 76 mm?
 Is an intercooler absolutely needed on E85?

There are some MP76mm turbos that have gone 100,000 miles already.  I know one guy how keeps pushing bearings on em though.  The 70mm MP turbos have a damn near perfect record though... but I would say that turbo is just to small for you.

You can use ball socket flanges (which leak under boost) or use Vbands.  You can get all the junk on Ebay or pick a favorite company to buy them from.  Scummit and Jegs all carry the junk as well...

An intercooler is not REQUIRED when using E85, no.

You can also just buy an On3 kit with the MP turbo upgrade.  I have seen some junk come from them, but others say its all great.  YCYDYP.

I will go v-band for sure.
 I might have found a gt45 with a 76mm housing & a 1.04 or 1.14 exhaust.

Is that 352 originally a 352 or was it bored/stroked to get to 352?  I'm curious because my '66 F100 came with a 352 and I haven't seen one modified to the same extent as yours.
