im not for sure on all the exact details kb would haft to chime in on here but i do know that the s475 has a much bigger hotside 1.32 and the downpipe is 5' vs the mp76 which a hotside of .96 i beleive and spools alot faster. The s475 will produce way more power vs the mp76will run out of steam around 16psi (this data was gathered by me threw other peoples set-ups) the mp76 would be a good turbo if your trying to get about 550rwhp tops but if you want anything more than that you will be pushing the turbo to its max effiency!

 

yep its obviously going to have more lag than the mp76 but if you have a good size converter,right gears,and hydroboost you should be fine!! if not a little 75 shot never hurt nobody! haha besides the borg warner will make masive power vs the mp76, check out wilderacing videos.... wow

 

The S400 turbo comes in many variations. Using the 1.32AR would be silly. It also comes with a 1.10 AR and maybe one smaller than that too.

 

Thanks for the kind words guys! The turbo I have speced for you is a S475 with a 83mm turbine and 1.10 a/r on a T6. Should spool quite well on the 6L

Flipped manifolds aren't a done deal yet. Really not liking them with all the other stuff you have to move to make them work. (coils, plug wires, coolant tanks...) But gonna to a little more looking into them be for the concept gets axed completely. As for valve train noise and tiniyness with my manifolds, there is no such thing, I build them out of sced 40 PIPE, 3/16 thick, not 1/16 tubing like other kits. That's about the same thickness as stock manifolds. They are VERY beefy.

 

KB will also be doing a BW S480 kit for me very soon!!!! and I honestly can't wait!!! from what i hear, the BW turbo's are an awesome choice and just look so awesome! The turbo is just plain massive.

 

i thought he was running the 1.32ar because its cheaper, so it wouldnt be silly to run that turbo because its cheaper than the 1.10 http://www.tpswestpalm.com/list.html

 

370 came in friday... gonna try and get the motor put together this week once the heads come back. here are some pics that i took of the few cars we have at the shop! enjoy , more too come as we progress

 

What is the difference between the s475 and the s472? Could you not use a small shot to get the 1.32ar to spool?

 

im not really sure what the difference is, but yea you could definately use a little bit of nitrous to get it to spool up!

 

The difference is one is a 72mm and one is 75mm lol. You can find one cheaper than that link you posted too
