Just a heads up for anyone thinking of going with the Modular Turbo hotside and an On3 turbo. It works like the two were made for each other! You can check it out in my build thread in my signature.

I was also wondering about sizing. Want to do twins on a 408 but not sure of sizing. What a/r's would you guys suggest for twin 70's or 76's? Want to make 8-900 hp with decent spool up on the street. Just looking for suggestions or input

I ran the ebay t3t4 for years on a hayabusa with no issues good cheap turbos. Why buy from on3? Its the exact same china turbo most people bitch about but costs more to gave their name engraved on the cover.

Because South America is still "Made in America", right? (Just down south... further south... past Texas... and we're ok with that)

1) I'm rear mount and
2) the 3" dumps about 24" from the turbo out the tailpipe.
Got my dyno numbers back. 550 rwhp @10 lbs boost
Not bad for rear mount.
Only issue I have is that I had put in 4.10 gears (before I decided to go FI). I burn through 1st so fast, I don't even see boost. Top out 3rd gear at about 115. Too low to finish the 1/4 mile.
First 1/4 mile run will be this Friday. Hope I do better than my 13.3 @101 before the turbo project. !!!

Thanks! Yeah, this was rear mount T76 Ball Bearing (On3 Performance). Specs are posted a few posts above.
I was told that if I went with the journal bearing, the T70 would spool fine, but the T76 might have problems given my current setup. But when I mentioned that I may want to go forged bottom later and up the boost to > 10 psi, (and drop the rearend back down from 4.10 to 3.42), my guy said I should go with the T76 Ball Bearing. That way it will still spool good with current setup, and would give me the room to grow into the forged setup. The T76 BB will support >700 rwhp, which is more than I would ever want to see in a convertible.
Next steps, drop back down to 3.42 rearend (or 3.23... haven't firmly decided yet), then go forged bottom, then up the boost, then buy new tranny and driveshaft. Then see what else I can break.
