im currently in the market for an s13...once i get a hold of one i have chosen the sr20det as my power plant..

now im still doing reading on the different kinds of SR20's...but the nature of my question is this..

now before i continue..i should state that i am very new to the nissan scene...i was heavily into hondas, but recently sold my Si in order to persue my RWD dream..that being this 240..anyways...i know that with honda..in order to have a *RELIABLE* boosted engine...although i understand that a good tune is key for reliability and maintanence...one must build the block..resleeve it, forge some internals...replace valvetrain with a stronger one to accomodate the new lifestyle of the engine....

my HP goals are about 300-350WHP...i understand that once one swaps in an SR20 it bust me refurbished with a new gasket set, timing chain, pumps, plugs , wires, fluids etc etc...this is a given...i also understand that stock sr20s range from 200-220 hp depending on the class of the SR...i believe if i remember correctly the stock boost was 7 psi....

now for the core of my question...if one were to constantly boost around 12-15 psi on a daily drive...what parts of an SR must be rebuilt?..the make up of honda blocks and nissan blocks are different..i dont know if resleeving is necessary..or if forged internals are either...i am reading many many posts here on swaps..but cant find any on rebuilding these motors with aftermarket forged parts to support higher boosts?..is it needed?..i know an upgraded turbo/intercooler/manifold are great ways to boost higher..but really what my main concern is..is the reliability and life of the engine....i'd appreciate any input...
