I would go with the biggest you can fit under the hood! I think you would have your hands full with anything bigger than a 88 but you are not going to be happy until you have a98 or 101 under the hood. Is it done yet!!!

 

Your right, I need the biggest one I can fit.....

I'm working on it, don't worry, Its just going to take time.

 

check www.forcedinductions.com or head over to tech and pm drturbo. hes probably going to recommend something around a s91. definitely going to put you over 1000 hp with air to spare. if youre looking to go real big one of the new FI-98x units would put you up there above that and from whats been said the spool on these new units is pretty quick for a large frame turbo. drop compression to around 8.5:1, less cam, less gear, 5" dp. my only worry from there would be running out of head. at a point its going to be like trying to fit 10 lbs of **** in a 5 lb bag. what kind of numbers are your heads putting out.

 

yeah im with the guy above about running out of head. If your going with a t88 or larger I would think you would need a tfs 215 or an afr 220. Especially with that many cubes.
I would look into sleeperz28's car. twins, afr 220's, 1000+rwhp, think 383 but not sure. Also another car on www.forcedinductions.com that jose did. 355, ptk kit, single turbo, port stock casting (AI), t76gts or t88 and also 1000rwhp+.

 

I will check em out, my heads flow right at 300 cfm@600 on the intake....forget the exaust, but If I need heads too then I'm not going to bother with it. I will just go LSx

 

That limits you to 145 mph (assuming 1:1 in the trans and a 6500rpm redline). You're going to want to go faster than that.

3.23 is probably more appropriate (that leaves room for as much as 167mph).

 

yeah, I know.....I learn more everyday....Most likely spin alot more than 6500 too. I'm thinking 3.55 is going to be best but I need to figure out exactly what I want to do first.

 

Yep. On a dedicated race car, gears are one of the last things you should choose.

 

And I have a 9" so its not a big deal.....2-3 hours, I'm sure even after putting it together they will still get changed a few times

 

mike, 300cfm is PLENTY on an FI car.
Cars with 270CFM heads will run what you want, your fine for heads

 

was just going to say the same thing. 300cfm's is plenty, no need for heads.
maybe a 3.42 gear?

 

Y did you put a pic of yourself as your avatar.
