stock to stock comparisons are dumb. Who leaves their car stock if they care about performance?
My point is that little turbo awd cars (sti, evo, eclipse gsx, BT a4)can throw you back in your seat much better than big v8 cars, unless those v8 cars have slicks and modified suspension.

That statement is incredibly general and far from true.
True to a point. If you take a V8 and I4 and put the same size turbo on them you that is maxed out on both cars you end up with the same amount of power. This is because the air is divided into each cylinder with more air into each cylinder on a 4 cylinder and less air into each cylinder on a V8. This is why a GT35r on a 8, 6 or 4 are going to make the same amount of power. The power bands are just going to be different because the displacement is going to effect the spool up(boost threshold).
Now if space is limited to a NA V8 vs a turbo A4 then it becomes a completly different story. This is also exactly why there are rules in racing and why you dont see FI V8's drag racing against FI 4 cylinder cars, but will see NA V8's racing against FI 4's while using the same fuel. Doing a Turbo V8 is not going to be easy since its a tight fit as it is for a NA V8.
Again, don't see the relevance since we are simply talking engines. My point was you can fit more air and fuel into a larger space (ie a larger engine); nothing to do with the car the engine is in.

My only question was what car were you referring to that ran 1.5 second 60fts? You said it as if to compare to the G8, so I'm curious what car and how modified it was.
I dont know many V8's making 400+hp per liter, but then if they were they would be pushing around 2000 hp.
BTW I said GT35r which happens to be a turbo V8 people do use. They have to run it at lower boost levels to get the same amount of air, if they try running higher boost it just acts like a chipped K03 on our 1.8 liter with the power peaking really soon and then falling on its face. I used that as example becaue the only difference between the 2 is the displacement of the motor but yet the 2 will make just about the same peak hp. It is just plain stupid to compare a GT35r 2 liter to a V8 running a GT45 since anyone in their right mind already knows if both are pushed hard the V8 is going to make enough power. Again like I said this is a forum of adults not a preschool for 4 years olds. Hell it isn't like I dont have freinds that drag race V8's that run in the 6's.

im now havin a boost problem with my k04, its got the giac program chip, and it spools super quick and holds 15psi till like 5 grand and starts dropping boost pressure and by the time im a redline and shifting im at 10psi. i dont get it

Anyone that finds this thread and is wondering why the same turbo can't be matted to every engine with similar results, this site is a very good read!

that's not a problem, that's the way it is. The baby k04 can't move enough air to hold 15psi to redline.

Back the train up, LS2??? I just happen to have access to that very motor. Is there info or anyone else whose done so?

search Guruman on audizine... He's doing the swap now. You can get an adapter plate to bolt the LSx to the 01E transmission. It should hold up to the power.
