hey guys i while back ive been asking a few questions about turboing my 6-port series four rx7..wel ive got everything sorted and bought a few bits n pieces n i was just wondering if anyone knows what power figures they recon ill be making at the wheels

this is my set up:



bridgeported series 5 turbo end plates

large extended ported series five turbo intermediate plate

custom exhaust manifold (see below)

50mm external wastegate

walbro 800hp fuel pump

1000cc primarys

1600cc secondaries

garret gt 35/40 turbo

3 inch exhaust with no cat,high flow muffler into twin high flow mufflers(twin system)

turbo rotars with 2mm scr seals

jatco automatic manual shift valve bodies and 3500 stally

front mount

wolf 3D standalone ecu

standard series five inlet manifold with all the emission bog removed



so does anyone know what power they think ill be making at the wheels?an idea would be greatly appreciated



thanks

 

the small hot side of the turbo is gonna limit you to 400ish hp @1 bar. imo

 

big overlap and small exhaust don't work too well

 

Yeah thats totally the wrong turbo for that kind of porting..

 

what turbo would you reccomend then?what size exhaust?thanks

 

maxt has a t51 on his half bridge....

 

what about a garrett GT42?

 

that would be a good choice too
