it might be...but the same questions are asked by new people everyday...and you all say you search....if you go to
http://www.google.com, and type in SR20det, you will get like 30pages of information..swap details, pics, everything you would ever need.
http://www.phase2motortrend.comhttp://s ... ds.comhave most of the details regaurding EVERYTHING you would ever need for the swap.....
ill answer your question though:
" screw nippon and go with afterdark or heavy throttle and pay 2000+ or should i peace the motor myself."
sure you can...but can you piece together all the parts? can u get an ignitor chip for a good price? ecu? wiring harness? people try it all the time, then ask the forums for parts 2 years later, when they are still 'piecing together parts for the swap'....its up to you, but i would make sure you can get everythng you will need first....usually its better to pay extra $$ and KNOW you are getting a complete motor, and wont be running into problems with cut harness, missing ignitor chips, dented oil pans, etc etc..
" can buy the engine and transmission(which I'm assuming is just the bell housing) for 1000 plus shipping"
thats amazingly cheap, and obviously not a complete motor, you will spend over 1500 imo trying to find the missing parts, if not more, and have one hell of a hard time....
"sr into my 240 for 2300 with the stock side mount intercooler,"
thats not amazingly cheap, i think you can do better....and u might wanna think about upgradeing that side mount to a front mount...side mounts are usually 300 or so, and arent really worth it imo...
"Has anyone dealt with nippon for sr20dets."
nope, not personally.
"place to go for true Nissan enthusiasts"
eh, sometimes : )
"I am starting to think twice"
its always good to think once, then rethink a second time : )
"Dude, you don't have to be a diak when you reply to my posts"
i know, guess i just am sometimes : P Ill work on that : )
you can always IM me at li240sxrep if you have specific questions, but for general questions, i would prefer you have some background, but your reading and researching, which is very good : )
