your gonna want a T6 flange for your cubes. I run a Garrett T6 flange 74mm on my 383, the upper rpms the car puls like crazy...picked up 36RWHP from6170-6250rpm.
Mine is off a detroit diesels semi truck
...does its job great for a 300 dollar brand new rebuilt turbo!

twin's are expensive! I'm taking that shot to the pills as we speak. I almost wish I had never done it and I haven't even done the install yet! You'll be a professional parts collector before it's all said and done. Big singles give ya some lag and lag is traction. I fell for the ole twin deal and instant spool. I'll never hook on the street. Looks like I'll have to just play with the supra's on the interstate. Wait a minute there aren't any in Wyoming. Well look out cummins and duramax lol. Good luck nonetheless. Chris

if you already have the kit just get a bigger downpipe and a t6 flange, I wouldn't do twins because your gonna end up spend spending more money than if you went with a big single. A 88mm would be about right for your setup and 2 76's will probably be way to much.
If one 76 supports 800hp(estimate) than 2 will go for 1600hp. and exhaust from one side of your engine probably wouldn't spool a 76. Full blown race cars run 2 76mm's and go deep in the 7's. If your going to run 2 for the street 2 67mm t3's would probably be more than enough.

you know i've probably looked at those heads a hundred times and never noticed that they made those. i went back and looked and noticed the flow chart with the 3.900 bore. thanks for the heads up.
if you read this article on Tim Lynch's street car, i know it is a Ford, but he has a 362ci with twin 76's and makes 1308hp at the back tires. why wouldn't it work for my set up? http://www.musclemustangfastfords.co..._lx/index.html

he has a set of ported TFS Twisted wedge heads on it. I'm sure Tim and Steve Petty ground a custom cam for it. Why wouldn't those items be affordable? I had planned on sending my heads to TEA and having a cam ground for my set up.

Go at least 88mm turbo, look at the garret gt-88. The sponser forcedinductions sells it for $1249. Very good priced and will support 1400 hp flywheel and 1000 rwhp thats a t-6 flange and its a small $250 more than a tc-76 or 78. The t-6 flange will allow you to grow more for future upgrades. Go with the 1.08 a/r if your wanting it to spool faster and be more streetable. Just got off the phone with them and thats what they said for my setup which is similar.
