even with a 5 speed swap plus the 3.0 swap you are still looking for a gain of 75-85 Hp at the wheels
we are talking around 50% on a N/A engine

far from beeing easy when you look at what's available on the market , parts wise

if a 420a was able to make 203whp when it makes 140bhp, WHY with a much larger engine that is rated at 200bhp would I not be able to make 200whp? would the restrictions be that much, see what i'm saying? no offense or anything I know u guys know a lot, maybe all there is to know about these engines, but I would just like it to make sense to me since some things just dont seem to make sense.

first the engine is not rated at 200 bhp it is the whole drivetrain that is rated at 200 bhp, meaning the whole exhaust system, the computer, the whole intake system
and last time I checked we are not using any of those parts in a 3.0 swap

now this beeing said have you seen the work needed to bring what "used to be" a 420a engine into the 200 WHp ?
I say "used to be" because the only thing left from a stock 420a is the bare short block and the valve cover
pretty much everything was either a custom made part, an aftermarket part or a swapped part from another car/model
and that included the whole drivetrain too you have no idea the works and cash invested in the bulletdsm N/A venture and this car is pretty much undrivable on the street

now back to 6G engines first you were talking 250 Whp but now you are talking 200 WHp which is a realistic goal for a 3.0l/ 5 speed swap with good modding that would be around 235-240 at the crank
serious headers like the RPW long tube kit, profesionnal porting of the heads, serious camshafts, a better flowing intake system from the CAI down to the cylinder head, UDP, 2.5/3.0 inch catback, a tunable fpr and all the other old timers tricks should bring you there or close

the next 60 hp to get the next 50 WHp will be harder, much harder ...

see, theres your other problem.  building an engine for na is waaay different than building an engine for boost. two totally different directions and you'd have to do ALOT of things over or different when you try to boost.


and the sad part of spending all that money on the all motor build on the 420a, he only runs 13.8. not even close to worth it when people on there could boost em for around the same price or maybe less and walk all over that thing and still be able to drive it home
