Best turbo for a 13BT Bridge dowelled motor
 

Hey my Turbo RX3 is almost done I just need to pick the turbo.


What do you guys reckon is the best all around turbo for as built bridgeported 13B S5 engine.

I need it to make close to 400 whp under 17psi withought being laggy and then be able to put down over 500-550 with race gas around 22-25psi.

any ideas and links would be great.

Thanks
Tyler

not a single reply?

I thought this forum had some heavy hitters?

Try one of the turbo forums here. Its a little more common in the newer generation 7's.

Jerry's semi P port with ITB had a turbonetics T72 ball bearing, sorry I dont know what the specs are...I'm using a to4 60-1 .96 hot side and 70 compressor, the motor is street port not bridge.....But yeah try the single turbo section I'm sure you'll get more response over there.

Agreeing here with Islandsnow...for a bridge-turbo motor, it will need to be a decent sized turbo for the size of the exhaust pulses you'll be putting out.

T-72 or larger for the fun of it. I'd go Garrett GT40 and a 60mm wastegate. Not toooooo big and laggy like the 42R for some drivability. A 35/40 will probably run out of huff if you have a pretty decently sized bridge.

Are you running S5 Turbo rotors or FD rotors? Apex seals? Internal mods (race bearings and gears?) Fuel setup? ECU? Gearbox? fDecibel regulations in your area? All-out or occasional daily driver? Lots of things to deal wtih ya know?

The forum members usually like more info so accurate help can be given.

Give us a few months to a year to finish one of my projects. TII full bridge, identical turbo as Jerry's but smaller T70. I hope it is enough. :)
