Hi guys, havent posted much on this site but i recently got compelled to buy a 79 malibu. dont ask why but ive always liked the g-body and i just couldnt pass this one up..
its a plain jane 305/th350 malibu, and th ehandling and power leaves room for improvement to say the least.. sp here is the outline of what id like to change and the question of weather its a good route to follow...
(there is a sister thread in the suspension section)
Ok here is my plan (or plans) ditching the 305. and replacing with diy turbocharged 350.. now the first route is the cheapest and that involves a 290 hp goodwrench motor (1650$), welding a single turbo manifold for passenger side and bolting on a gt-40w or holset hx55 that i can buy locally for about 300 dollars new in box.. that engine should survive 6-8 pounds fo boost if i blow thru the quadrajunk and possibly add a diy waterinjegtion system..
the second option would be a beefier 350 from PAW with forged pistios, world product heads and a turbo cam (2800$) a set of schwartz manifolds (1000$) and two t4 flange turbos (minimum 2000$) a real blow thru carb (500$) racepump and regulator (400$) and so on.. this setup will also grossly overpower my th350 tranny and skinny rear so is the first plan viable?? or is the an in between plan?? somthing im missing??
(ps nelson racings engines are a little out of the budget .. )
I with ya except for the carb... wouldn't a FI set up be better? Or how about an LSx plus the trin turbos. If you have some good junk yard connections, the motor shouldn't be too hard to come up with.
you are propably right.. it just seemed like a cheap, fun and "high wow-factor" way to get to 450 hp! but the forged bottom end would have plenty of room for improvement... just turn up the boost and wait for somthing new to break!
An LSx is very hard to find over here... and the only reason im not planing on running efi just yet is cost... and megasquirt/VEMS seem like they have somewhat if a learningcurve...
