lose the ebay 38wastegate.. next thing you know the gate wont open and your car will blow up.. i'll sell you a tial for 130shipped. 7psi spring.

Re: my very basic ls turbo build thread.
 

used them before for over a year with out any problems. Iv had a tial 38 and a ebay, only diff was on the ebay the diaphram would rip because the bolt for the banjo fitting is too long so I shaved this one down so it wont rub.

Re: my very basic ls turbo build thread.
 

just my .02cents. its like taking a risk with ebay junk tho... but do as you please.

gonna start fabbing up the down pipe today, unfortunately its about 22 degrees out :s

Re: my very basic ls turbo build thread.
 

today was FREAKIN COLD
im so tired of the 20 degree weather around here, its the coldest its been in 11 years!

so today I wasn't down to spend the whole day working on the hb but I did run a few errons and grab some small stuff that I needed, unfortunately the throttle body gasket I bought was a hunk of crap, it was a feelpro but the bolt holes were all off by about 1/4" so tomorrow I have to run to honda to get a new one.

I also have to cut the radiator brackets because I had to cut them when I put my dc radiator in for my all motor setup. its extra work, but its all good since now I can move the radiator as far away from the turbo so the down pipe will clear it even better.I think Im gonna also make a custom radiator overflow that I can hide away some where.

Re: my very basic ls turbo build thread.

Re: my very basic ls turbo build thread.
 

is this a street car

Re: my very basic ls turbo build thread.
 

of course.
Iv ran exhaust out the bumper on a sohc turbo I used to have and didnt have any issues with the po po's

Re: my very basic ls turbo build thread.
 

how loud is it
and is their a diy on welded diff or more info

Re: my very basic ls turbo build thread.
 

its actually quieter then like a normal under car open down pipe because it doesn't resonate the whole car. its also alot better on fumes and exhaust ..etc

as for the welded diff, if you know how to take the diff out of the tranny then all you have to do is weld the two spider gears to the drive gears, Iv put about 5k miles on mine with out any issues and I have a 231whp all motor b20 vtec in it.

the welded diff makes parking lots kinda suck, but a hell of alot cheaper then buying a good lsd or spool. and if it breaks a stock diff isn't very expensive.

it also greatly improved cornering in my car which I couldn't believe at first. its much more of a point and shoot car now.

Re: my very basic ls turbo build thread.
 

shits weak haha did you find that part?

Re: my very basic ls turbo build thread.
 

Dang son i wished i would have bought the chrome EMUSA wastegate. Those are good wastesgates from what i hear. Me and two of my friends are using them.

Re: my very basic ls turbo build thread.
 

only thing I dont like about my wastegate is it seems to sit up hella high so Im gonna have to cut out some of the hood support or prop the hood up or something. or just let the natural route of things go and have the w.g. beat the sh!t out of my hood lol.

and justin.... yur shits weak. Ima hit u up 2marro 2 get random assorted ls junk

Re: my very basic ls turbo build thread.
