someone on another site mentioned that a turbo back exhaust and intake will gain 70hp at the wheels, does anybody have dyno sheets from these mods only?
+70hp from bolt-on's?

Intake, complete exhaust from the turbo back, and a manual boost controller set to just under fuel cut is well known to give you ~320 crank hp, which is ~90 hp gain. So yes, the guy on the other site is pretty much dead on.
I don't have a dyno sheet for this - most of the guys doing this don't bother, they don't have any way to tune the car, so why spend the $$$ on the dyno at this stage?
However, that said, this has been done literally hundreds of times.

Believe it. I've got the full turbo back, intake, 2.5" hardpipes and larger FMIC and I'd say I have around 70 HP to the wheels running off the wastegate. IIRC stock boost on a manual supra is 6.7 psi, I'm somewheres around 8.5-10 right now with just what's on it. I'll have to get an aftermarket boost gauge to see for sure though...
k&n intake bic ddp stock 125k mi cat stock catback (had some holes) rigged turbo-ic pipe mbc @ 10-11ish (dying off at 5000) I made 266hp 292tq to the wheels.
if you consider MBC as a bolt-on then yes, otherwise no, it will give you max 20-30hp (intake+exhaust)
^ Glad someone finally spoke up. Maybe increased boost is implied in the original post but without it he'll be lucky to see even that.
