Both 3SGTE motors will bolt into your car but you'll need the ECU's and have to do redo the wiring harnesses and other ancillaries. Also, the 1st Gen with WTA IC will be fine will your stock hood but the 2nd Gen engine will need an air scoop if you run the stock top mount ATA IC.
I'd go for the first one. The second gen is a better built motor and takes to alot of mods alot better than the first gen. Both of those should come with ECU's. I know the first one does as its in the item desc.
thanks for the info what exactly do i need to redo on the harness i know some electricians and my dad is one too so wiring isnt an issue.... i dont mind cutting a whole in my hood for an IC
