"Best Turbo for a stock C5"
A friend of mine just bought a beautiful stock 2001 convertable. We were into the 5.0s years back, and he's built a 9 sec turbo foxbody, we're both quite learned on turbos.
He would like a mild, driveable setup (it's a 6 spd manual too)
I know about fuel pump, injectors, HP tuners, valvesprings, etc.
he'd like to use the stock cam too. Can you guys suggest a quick spooling, pump gas power limited turbo ? looking at a T4, single turbo
I'm thinking around 500 RWHP and 10 PSI ?
Is the stock cam OK for this too?
any other input ?
Thanks.

I wouldn't waste my time or money trying to make only 500 RWHP with a turbo build. That's a hp build goal ... I'd say just about any 70mm or 76mm unit will support that power. I had a cheap master power MP T70 with an .96 ex housing make 565 RWHP rear mounted. Spooled quickly on the street and ran mid 11's with a terrible 2.0 60 foot in an automatic vert.
The exact same turbo went 9's in my old mustang coupe with a bumper dragging 1.28 60 foot on full tilt.

Thanks. More concerned about driveability, quick spool...stock H/C/I, pump gas, good clutch... looks like 550-600RWHP at about 10PSI, awesome

Drivability will be like stock. It doesn't take much cam to make power. My 1000 RWHP turbo mustang had a .565 lift cam. I've driven my rearmount corvette from 10pm until 4am hitting 1/2 a dozen street racing spots one night without a hiccup. I would even drive it to work on sunny summer days. Until you hit the go pedal hard, it acts like a stock corvette .

He would like to keep the stock cam for fuel mileage...

I'm know there's stock cam builds around here. Hopefully they'll share their results.. I'm certain a mild turbo and stock cam will get your buddy where he wants to be. From what I recall that cam has a turbo friendly lobe separation.

Wow, having come from pushrod-302's, I'm frickin amazed how easily these LS engines make power (and don't blow HGs or crack/split blocks easily either lol)

Stock block (302) to stock block (ls) you've gotta go LS all day. My stock block 302 motor ran high 9's in a foxbody. I seen a stock 6.0 block in a foxbody run high 8's and these days they're faster. I love my pushrod Ford R Block though. When I put my race car back together, my ford R block motor will run high 7's. Until then, I've got a 4 year old I'm supposed to be setting a good example. Lol.

I'd imagine spool time would be a little better with the front mount with the same turbos. I couldn't tell you exactly being that I've had 5 turbos on my car between the rear and front mount combos. I can tell you that the heat generated under the hood is tremendous. I didn't particularly like depending on a scavenge pump for the oil return on my rear mount combo with a fresh forged motor

You could probably go 8.50's with a 1/2 filled stock 351W block. I would definitely try to but I fell into a fully machined R block 347 for about $1200 probably 8 years ago. I still have it. I Hydrolocked a cylinder a few years ago and haven't fixed it. I've been having to much fun with the corvette
