Forged 2.3L GT3071R

Title says what i am planing to build. I have a few questions
-were can i get T5 forged pistons maptun? (only place??)
- wat else will i need to make sure i don't blow the bottom end to pieces ie. rods
does anyone make them forged or stock ones strong enough . any other pieces i should replace with stroger ones
-Can i use nick's larger throttle body??
-i am planing on transplanting this engine into 900se coupe?
- is there anything major i should be aware of ???

-- You can get the forged T5 pistons from Nick
-- The stock B234R rods are plenty strong
-- Throttle body is likely more of a benefit for a N/A car, but I'd be curious to see whether there were any gains.
-- Keep the oil pan and accessories from the 900 SE

Good luck and have fun!

#1 read the 234 swap thread

#2 9000 internals are good to 400ish hp probably closer to 500.

#3 I'd call up Paul at Automotion. He's done this setup on a few cars already so I think he could point you in the right direction.

Jeez, I wish I had 5 grand to blow on a setup like that.

Edit: now that I think about it, I would suggest buying about $1,500 worth of brake and suspension upgrades before even THINKING about forged internals and 500hp.

QFT. I don't know how anyone could even think about serious power level increases on the OG9-3 chassis without serious suspension upgrades. I've been driving my stock 9-3 (power wise) with a full Koni kit on my car and the chassis is scary. Need more braces and better brakes are a must for higher than stock power....at least better rotors and pads.

Is a GT3071r even capable of 400+WHP?

I would think mid 300 whp is about all they are good for?

Probably want a GT3076r for 400+whp & if you are looking for new pistons, rods, etc you might as well convert it to a 2.5L

To be fair, I'm not so sure he's done his homework on this one. And no, I don't think there is anyone out there with the GT3071r on a 2.3 making 400+ whp.

There are quite a few versions of the GT3071R out there, not sure about the specs here?
Anyway I know of one 9-5 with this turbo (A/R 0.86) that dynoed 477bhp, not sure what that translates to as whp but surely it's over 400?
So as long as the engine is properly built up and all the components work as they should together it should not be impossible to reach +400whp

JK is right i just gathering the saab communitys input on what i need.
ohh and all of you saying i need suspension that will come to before the engine

guys i not saying i just going to drop the engine in and drive it. i will get a bigger fuel pump. and injectors. what i was asking is there something that someone would overlook

ohh and this car will "be up on blocks for a while" well building it
Edit: i meant 400bhp(with some nitrious maybe 400whp)

Pade nailed it: top HP with the 3071 is dependent on a few things, one of the most important being the A/R....a .64 will get into the mid 300s pretty easily and safely, a .86 can get 375-400, and a 1.06 can get 400+

No special cams are NEEDED for 400bhp.

You can use cam's to help adjust the powerband to better suit the turbo but its your choice. I would say you need to talk to your tuner first when you get to that point because then you'll be getting a custom tune.

I'd stick with stock cams, and maybe work with some turbo maps and adjustable cam gears to adjust the powerband where you want it.

Turbo cars like 'economy' cams....highly strung N/A high lift cams actually hurt performance. Although a medium duration is nice for cylinder filling.

Well yes and no. Yes, they like "economy" cams, but they aren't the ideal performance setup. More lift is good, minimal overlap, and not a ton of duration.
