This might be a very dumb question. What is the difference between the 95 Cosmo twin turbos and the US spec twin turbos?

Is Cosmo what they call the 20b's?

Would cosmo turbo's bolt up to a 13b?

Would it produce more or the same power?

Thanks

 

if the cosmo is a 20b it has more displacement so more power will be available in lower rpm ranges. I don't believe it is as simple as replacing the engine in the 7 with a new one. I believe some parts must be changed and stronger mounts for the larger engine. A new fuel delivery system must be composed to allow more fuel for the extra rotor. the engine is also longer so it may have to be tucked further back toward the firewall. Then again the 13b does sit back rather far in the engine bay. I don't even have a 7 but I think that is what's up.

 

elmo, is that 240z an L28 w/ diesel crank or something of that nature?

 

Cosmo's came with both 13b (13BRE) and 20b's.

 

Is the actual turbos on each one the same? Do they have the same exact turbo's on the 20b and 13b?

 

edit: just noticed your only talking about the turbos, and not the entire engine. my mistake

 

The Cosmo Turbos are smaller! Or.. at least one of them is, the other is similar to ours.

 

20b is the 3rotor engine 2.0liters instead of the 13b 2rotor 1.3liters. I don't know about the turbos though.
It can fit in an FD3S but you need a subframe and a bunch of other things to make it work.

this is true
not an ugrade Id say

our stock twins are great
theres also pettit high flow twins or bnr stage 2 or 3 twins that are ugrades for power near 400rwhp
