Was up everyone,
I want to swap my b16a2 for a straight B20b non vtec into my 00 si. I have a T3/T4 turbonetics turbo on it. The reason for doing this is because I fucked up my rings. I just decided to swap in a straight b20b and fix the b16a2 with no hurry(put it in another project). I got a P75 OBD2 ecu(98) and an LS manifold(96). I already have a GSR tranny that I will also be using. Does anyone know what stuff do I still need or what will I have to use from my B16 to complete this swap. Everything is stock(B20 longblock). What PSi do you guys recommend for a safe daily driver also taking into consideration that the B20b has a lower compression of 8:8:1. What do you guys think or recommend. Thanks everyone in advance!!!

i reccomend using your head and tranny from your b16

yea so do i put the b16 head on the b20 - and use the b16 tranny for short gearing or trade that for a gsr (loved my gsr tranny) -- do not skimp on fuel management !

I dont want to go vtec, that is why I did't bother using my b16a2 head. I just want a straight b20b and drop in my t3/t4 turbonetics turbo.

with a stright up b20 your going to be making 140, then bolt on turbo and run what 6 psi- not worth it, you could do an all motor b20 vtec and pull close numbers to that and not have to what to hit boost, and for alot less money since you already have the parts. If you have the turbo already you could bolt that on to the b20 vtec and make that much more power. as for your left overs slap the b20 head on the b16 block! ive heard of it being done " the reject motor" this guy up here got all the parts for free, and built him selft a back up motor in case his blew, and ended up throwing it in a hb and made 142 hp so... but its all up to you in the end of the day and depends what your really looking for - b20+turbo .. you should have gotten a b18b block over that they handle boost alot better due to sleves
