20g for 2g cars

[67racing]

at dsmparts.com they sell a 20g already modified to fit the 2g cars, bolt on. has anybody had any experience with these?
how does the 20g work on a stock engine setup (with forged pistons) but stock fuel system on 2g engine?

it'll bolt right in place with no modifications, but with stock intercooler and fuel, you will only be able to run about 12-13psi. Toss in a FMIC, tuning, fuel pump, and 660's and you 'll have a really quick car.
