I have been looking Into the various choices of engine swaps availible for the 240sx. I have been doing some research and i’d like to some knowlegable opinons on what sort of potential the “S15 SR20DET Black Top” engine has with the typical racing modifacations; I.E; Performance Internals, Turbo/Intercooler etc. upgrade, Exhaust, Intake, etc… What sort of power figures could you be looking at? Thanks. ---

S15 engine really doesnt have much advantages over the S14 which is considerably cheaper. Sure you get a little more hp but the cost of driveshaft and/or rear diff to make the 6spd work negates the gain since you could put the extra cash into an S14 and it will be just as quick. Do a search there is plenty discussed on this topic. ---

Thanks for the info. About the swap/build; i dident mean 8 grand total swap and build. I’m looking to putting 5 - 8 grand in the engine build it self. ---

you could be hittin 5-600hp with that money you would probably be better off getting a s14 black top switching the tranny or if you already have the s15 then you could be looking pretty high horse power gains ---

get an s14 SR and do a nice rebuild with it. 8 Grand can be a lot if your going all the work yourself, but if your planning on taking this to a shop that money will disappear faster than you could imagine.
