SR20DET Swap Guidance

[Siberian Husky]

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...

is this the wrong forum for this question?...or....?

Right forum wrong task you shoud search...people ask this shit every day

a little help though
first off dont set out with a hp goal get the car running learn how to drive it well then up the hp a little at a time

for the boost question get some bigger injectors and a good headgasket

never ever mention hondas on here too much of a stigma attached to honda owners on this board because they all ask the same questions and never search

also dont bump your post after an hour a lot of the members here have jobs so they cant post that often

I find SR's to be fairly reliable. You can squeeze 12-15psi out of the stock turbo, (mines at 13psi, no problems) but I wouldn't push it past that. It would definitely be a good idea to replace the HG, as well as the valve cover gasket and the turbo gaskets. I don't think you would need to much internal work, SR's are built pretty tough. Replacing the valvetrain would probably be a good idea. I don't think you would need to build up or resleeve the block. For any boost past the stock you need a FMIC for sure, doesn't have to be fancy though. And better injectors would be a good idea.

Swap the engine in pretty much stock at first (except for maybe exhaust, downpipe, and a FMIC) to make sure you get it all running well. It can be a pain trying to find problems, when you already have upgrades that could be causing problems or needing adjustment, in addition to a new engine. And swap the engine in yourself, even if you have some issues or need help along the way, the knowledge you gain about your car and engine is invaluable. Good luck.

How can you have all of this "knowledge" and not know how to do a manual trans swap? Not to metion all of this was already covered
