So i wanna go all motor for now & then later do boost but i was wanting to get the hondata s300 then get skunk2 manifold for my car but some pple have told me that getting the hondata s300 well be alot that theres other ways getting more hp ..see my idea was of doing the hondata s300 & then get the conversion harness for it then taking it to a local tune shop & they were gonna ship my ecu for 100 & to install & tune like 700 or more.. but then some of my friends say to jst two step my ecu or jst to chip it ..

My current mods on my car was LS but swapped it to the jdm b18c gsr so it jst has intake no A/C nor P/S

 

for that setup s300 is overkill you can prob. just get away with getting a chipped ECU and get it tuned on chrome but a tune and a chip is still 500 bucks

 

damn so what could prob be the best to do ?

 

Your setup is easy and simple to tune overall its pretty much stock.

Depending on which ECU you are currently running you will need a chipped ecu to run either Hondata or crome. I personally like Neptune RTP at a cheaper price and works just as great or even better then Hondata.

BTW you cant two step an ECU according to your post unless the ecu is already chipped and running under some sort of EMS.
