Street/Strip Build Turbo E85

[Redsta]

I have a 89 auto festiva completely Stock, Wanting to do turbo e85 on the b3 low boost of course what turbo to get bov wastegate and where it fits best, maybe a n/a built b3 if so what cams rods crank pistons maybe a ported intake also wanting to keep it auto if they are strong enough, if not where to get them built or what auto to put in it

I didn't find any rods and pistons for b3 mate, that's a headache, the b6 is easier

Just swap in a b6t from a Capri, they're already turbo and built for boost. B3 rods are weak, the crank is single throw so they have harmonic issues at higher rpm at stock power levels, and the chamber design has a hot spot that will torch pistons under boost, there's already a noticeable hot spot on a stock engine that usually has all the carbon burnt off.

Get a junk Capri XR2, use the stronger trans and axles, and you get the harness/ecu to run it. It'l make 180 whp on the stock ecu at about 16 psi. Even if you spent $3k on custom forged pistons and billet rods and custom cam for a B3 you'll still need a XR2 trans and axles, might as well just use the b6t from the Capri.
