twin .63??
Will .63 turbine support a 418ci engine??
I have a brand new turbo from my 4 cylinder days that never got used. When I bought it , they said it would make 500hp.
I'm looking to do a twin setup, so I would just buy 1 more.
Let me know thanks

Do you have any more specs on the turbo, i.e., compressor and turbine wheel sizes, t3/t4 housing, etc.
Without additional info, I'm going to initially say that it will spool quickly but run out of steam before 6,000 rpm.
418 ci usually wants at least 0.82 a/r on the turbine side.

I don't have any info on the turbo. It was bought many moons ago. Either way, it's a t3/to4e setup.
With a .63 turbine. ---so too small for sure right???
Reason I'm asking , a guy at work with a 4 cylinder wants to buy it.
So I need to sell and buy 2 larger hair dryers that will fit my 418

Gtx is the newest billet version. .63 will work look at the guys running the ttix kit that had 6266 with a .63 housing. OP needs to know the wheel sizes as a t3/4 has a huge range of potential. I think the turbine wheel size makes more difference than the housing to an extent.

Open wastegates, largest dp's possble...probably get you to 800rwhp on two of them(.63)...depending on turbo. It would just lite up QUICK..maybe a little choked out up top but..that depends on where you're shifting at.

My Turbonetics 58mm turbos had the 0.82 a/r housing and all though they really sparkled at close to 900 rwhp, they were being pushed. It was to the point that I would be concerned about the reliability long term, but nothing lasts forever. Mine made 20,000 miles and were bought used. Now they are going on a TT 5.3 in a Malibu as is.
Spool wasn't an issue. They made full boost by the 30 foot mark without a two step.
He mentioned "no less than 800hp" and to me that means you're on the path to 1000+ but will need new turbos to get there. If the OP wants to throw on two 0.63 a/r turbos and squeak out ~ 800 crank hp, that's perfectly fine.
Have you tested them out yet?
