Pontiac Solstice Forum - View Single Post - Hahns Upgrade or LS2 Swap

If you really want the LS2, lil goat is right on point. BTW, upping the GXP to 400hp should cost no more than $2500. All you really need is a turbo, manifold and some ECU tuning. The unknowns are whether the stock injectors are up to the task of 400hp as there are no aftermarket one's yet. Stock internals are forged and SHOULD be able to handle that kind of power. If an old ass SR20 motor (crank is the only forged part in that motor) can handle 400whp, GM's much newer tech LNF should be able to also.
