thanks to 2k5sssc for the help

I wana make about 350whp and 350ishtq safely and reliable, and i COULD do it with the TVS but turbo is just gonna be much easier and efficient

bump

 

The synchronic BOV is great but stay away from their wastegate. I haven't had much luck with it. It's real complicated to set up. Now that it's set it's working well but it took a few weeks to get working right.

A garret T3/t4 50 trim is about 600 shipped for the same power available unless your set on the 20g. And the vulcan turbo many is about 100 cheaper to go with that turbo.

Umm... you can run a 2.2 alternator and belt (actually the belt is just a touch bigger if you want the part number) for about 145 new or about 80 out of a junker.

You can reuse you stock maf location on the intake by cutting it up if you plan on running a draw through.

IDK of anything else I can think of to save you any money. It all looks pretty good.


Have goodluck with the build!!!!!

 

very good info man. thanks

 

isn't your car for sale???

 

ha its always for sale for the right price man. seroioulsy though i bumped that thread last week from the dead for the hell of it just 2 c if any1 would throw any offers out

 

If you want to take my t3t4 turbo off my hands then be my guest.

 

ha how much?

 

Dont forget a stronger clutch too! If you dont already have one!

 

turbo now?

 

just shoulda bought a neon

 

HAHA!!!

 

lmao

 

Yeah, but whats unique about that. People expect a Neon SRT-4 to be turbo (well duh).......but they don't expect a supposed supercharged Cobalt to be turbo, which ups the cool factor.

 

hey how i see it is,is u got deep pockets,go ahead and make it a quad turbo if u can

 

**** I will throw it to you for 350$ with waste gate. Check my sig for the pix and parts.

 

not to mention tuning a wideband monitoring gauges a custom downpipe...i hope you can weld...a way to mount your ic...o so lovely the amount of work you have to do...not to mention the special intake for the manifold youl have to make as well

he treats his clutch right and it will carry him a long ways

if its not an ebay turbo thats been used and its a decent wastegate(tial) then your getting a hell of a deal and id take it...not to mention it would support your goals

 

Is that an eBay turbo?


eBay turbo..


You can get a eBay T3 T4 for $118.99 plus shipping and an eBay 38mm wastegate for $47.99 plus shipping.It would be recommended getting the good stuff the first time though.

 

sure is..m12 is on both and t3/t4 turbos have 7 fins not 6

 

yea you can tell its an ebay most of the time because there polished,look cheap and have the crappy looking plastic covers...and btw not sure if the wastegate would be a good idea...youd have issues...not sure if boost creep would be one

 

^Don't forget about the compressor being glued together :}

Cheaping out on a wastegate is a baaadd idea but if you're going to atleast get a Godspeed.I hear they are pretty decent.

 

Looks like an interesting project for sure. I can't wait to see the outcome. If you have any questions let me know.

 

Whats that outlet flange your talking about?I have a super20g from hahn,and no special flanges are needed.I have a s/c delete kit and the idler pulley setup for sale if your interested.
