I look forward to updates on this as things go on... I love doing new and eccentric stuff myself.. I was thinking of putting a small turbo on my XR500, but the plumbing would have been too much of a nightmare with twin carbs and twin exhausts.. and I have enough trouble keeping a head gasket in it as it is :P

I think the turbos will be good for your application, though you may need wastegates in addition... Also, in an ideal world you may look for a compressor wheel that is designed to flow higher air volumes more efficiently at lower pressures... I don't think you will be able to make use of all the pressure these are capable of delivering, and if you can trade a little of that for volume it may be worth it.

Good luck with it all and keep us posted!

yep waste gates and higher flow compressor would be good.

 Ya, I already figured I'll need wastegates, since the DSM guys need them with this turbo on a 2.2 4cyl. IIRC once they started making boost they said that even if they opened up the turbine all the way it still kept climbing.
  I've got almost 3.5x the motor and only twice as much turbo as those guys.

 I'll be starting with the standard HE351VE compressor and we'll see how that does for starters.
 Right now I'm just using a cast crank/pistons 2-bolt stock 454 bottom end. I have a couple other 454's at my disposal and one of them is going to be used for a new 496 shortblock. Using a forged stroker crank, bad ass rods, forged blower pistons and of course splayed main caps. If it looks like the 454 needs bigger compressors then I'll probably do it when I swap out the shortblock later on.

 But this car is a little on the backburner right now. I have 3 EFI conversions and a Northstar-Corvair swap lined up that have to get done first.
  I also may be installing an HE351VE in my fathers 96 1 ton chevy with a 454 vortec. He says he just wants about 5-6 PSI and he already has the turbo and a dodge intercooler that he wants to use.
 Anyhow I better stop before I run this thread too far off the rails.

I'm not sure on needing a wastegate, you won't be able to keep boost under 30psi, but surely shaft speed under 110k @ wide open no doubt.

My 5.9 can and will spool @ max open as well, but it can't get over 115 until 9k rpm

wastegates for sure, I dont intend to run over 15 PSI. I'm trying to keep the HP under 1100. Above that and everything starts getting way more expensive than I want to deal with on this car.

I have data logs of shaft speed kissing 130k on a 2.3  32psi manifold pressure around 37psi at compressor outlet
If I ever build a exhaust manifold that does not leak i'll put the waste gate back on.
