OK I'm wanting to turbo my LS and my good friend/co owner of Chaay Racing told me to boost my LS but build a B20 on the side and when it is done to put it in and boost higher. Will this work right? LS Turbo on B20 block?

 

it should. the b20 and b18b are pretty much the same.

 

ok cool
just let me know somebody if it wont

 

pretty much all b-series use the same turbo mani

 

really? so if i do LSVTEC the same turbo will apply?

 

either do LSVtec or turbo but not both... youd be in for a world of hurt doing both... and turbo is prob safer than the LSvtec

 

yeah i know but i was just asking
that would be taking it to its limits

 

All the b series manifolds will fit on each other. Its when final charge pipe meets the tb where there are differences in kits between the b18c and b18b.

 

what all can i do to build the best B20 block?

 

Find a b18b block because its cheaper. Send it to GE get resleeved it to 84.5mm and you'll have a little more displacement than a b20. Get a good set of pistons, your choice. Some eagle rods and arp head studs. Along with some crower turbo cams and some major head work. So many possibilities. Money and time is what you need.
