Title: Theoretical question...
Post by: Brett on June 20, 2007, 03:16:14 PM
Would the twin turbo pack from an FD, setup to run non sequentially, fit a 2nd gen?  Would there be any advantage over the stock single turbo on the TII?  Obviously a programmable ECU would be required - but would there be any worthwhile gains?  I ask becasue the FD runs 10psi as standard and the FC runs around 6psi,. My thinking is that a DCATTED FC will hit 14psi easily but the turbo is ineffeicient at this point, would the FD pack be more efficient?

 What are peoples thoughts? :3gears-lh

Looks like quite a bit of work. The other question is the stock supra or skyline turbos an option ??

Soon hopefully to be an FC engine owner (all be it in a FB) so future mods are being investigated :D

the manifold fits the engine, the only problem you will have is the twin turbo pack will not clear the FC lower inlet manifold.  The FD LIM is very slim (which is why its a bit restrictive)  you could make a spacer plate from the engine to clear the LIM but then you would need an FD downpipe and splt oil and water lines.  By the time you have bought a decent set of twins i would prefere to buy a cheap turbo kit from fleabay and you will get better results and everything would be new and fit straight on.  

not sure if the twins hit the steering.

iirc the xs power kit is about £300 with manifold and wastegate with lines and gasgets.
