408 turbo
408 turbo im new to the turbo world and have been reading the stickies for the past few days to get a better understanding but still unsure about a lot of things...
ive been going back and forth about a turbo motor and i finally made up my mind.
i decided that i want to do a 408 iron block and would like to put out around 750rwhp with pump gas.
my question is what size turbo would be right for me and what all would i need to accomplish it (pistons, rods, cam and anything else you can help me with)?
im probably going with a th400 and this motor is going in mustang
thnkas a lot

so how would i go about buying a kit? i dont really know what is all needed in a turbo kit. is there certain parts i should buy from other companies or should i buy a kit and upgrade the turbo or what?

of course u would want to go with forged rods and pistons, i would stay mild on the cam choice.Like the others said an 88mm should put u at your goals.To run pump gas u probably want to keep your compression around 9-1 . For the motor,most sponsors run specials from time to time so keep your eye open for that.
Since it's going into a mustang swap the hotpaarts will have to be custom made. I don't know of anyone making a kit for ls1 mustang. As for the motor a forged 370 ($2899) with a TC 76mm($1100). I would think this should get you to 700-750 rwhp.
thanks for the input guys.. i was actually thinking about going with a F1 at first but after riding in a few turbo cars i want something in the lines of that.
what would be a ball park firgure getting the turbo kit made for the car?

For the most part a smaller turbo will spool up faster lower in the rpm range(kick in sooner), however smaller turbo's will lose power higher in the rpm band. The S85 would be good and spool very fast for you and stay spooling in the higher rpm range, not exactly sure when it will start dropping off. You should go between a S85 and a S91. I would talk with Jose at forcedinductions.com as they are very knowledgeable with these turbos. The S Series turbos are some of the best out there.

I am building the same thing as we speak. I am thinking about keeping the CR around 8.5.1 and running 15-18psi with meth. Then maybe turn it up to 22-25psi with more meth to race with. I just need to order the pistons and cam, assemble the turbo kit. I wanted to run a 88mm turbo. What or who would be a good person to have spec a cam for me? What would be a good ballpark cam to be with? I have Dart 225 heads out of the box. Also what is a good intake manifold to run with this setup ls6 or FAST 90?

Keep the LS6. The fast would be a waste of $$$
that's almost the turbo right there.
An S88 or S91 would be awsome on a 408.
A custom kit is going to be more then your basic kits.
When mine was done 2 yrs ago it was over $8k for justthe kit.
My 1st question I always ask is has your budget and time frame??
I can see spending $15-20K fast............
