Hey everyone, Just updating you all on the new turbo from Dee, the ssac manifold and the install.
First, The install. 1.Remove heatshields, all intake piping, and hotside intercooler piping. 2.Unbolt 02 housing from turbo.3.Loosen oil feed from motor. 4.Loosen oil drain from oil pan and/or turbo if accessible.5.Remove water feed line completely from block and turbo.6.Loosen water return line from intake manifold and the back of the head.7.Unbolt BMC (brake master cylinder) and lay it on top of the studs. 8.Unbolt the manifold from the head. Carefully remove turbo as to not bend any lines too much (kink!). You will scrape your knuckles and cuss alot, maybe even bleed. Dont expect it to only take an hour or two if its your first time.
Next, Bolt the new turbo onto the mani. Bolt the water return line onto turbo. Then loosely tighten the oil feed line, make sure its loose enough to move it around and postition it correctely.Next, attach the oil drain tube on to the turbo. I had to chop about a 2" section out of the drain tube because the ssac mani placed the turbo at more of an angle. Put the whole assembly back onto the head. This is where its important to have the BMC unbolted and outta the way. Its impossible to fit it in with out unbolting it. Put a few nuts on the studs to hold the mani onto the head. Then start attaching the anncillary lines. Make sure to put the water feed back on!!!lol... Next up is to start bolting everything back up. 1st the 02 housing to the turbo, then tighten all of the oil and water lines up, this can be tricky, lots of patience and short throws on a wrench help. Finally tighten all of the manifold bolts in sequence per FSM reccomendation. Now the easy stuff, re-installing all of the intake and charge piping. Make sure to bolt the BMC back onto the vaccum booster.
A few things to note. Always use new exhaust gaskets unless they are the steel crush type and they do not stick to any of the gasket surfaces when you try to remove them. Also make sure to use new copper crush rings on all the water lines so you dont have to repeat everything twice. Use a new gasket on the oil drain tube. I like to personally use Permatex Super Copper hi-temp exhaust gasket sealer on all of the gaskets after the turbo. Its up to you though.
Now for some pictures.
The old turbo ready to come out!!!
Waiting for the new shiny manifold and snail.
Shzaam!!! lol . All done. (if it were only that easy)
Now for a few pictures of the new turbo and mani bolted together looking hott!!!!
One of the best pictures I have taken...hahah. seriously the focus and everything was right. Soo clean.
Ok now for the Stock turbo vs. Dee t2/t3 turbo.
I had the stock ca t22 pushing around 14-15 psi and that felt pretty fast. This turbo on the stock wastegate (6-7psi) feels slightly faster by my butt dyno. Boost comes in full by 2800rpm with no boost controller, unlike the stock ca turbo with the manual boost controller which spooled up about 500 rpm sooner yet died off in higher rpm. The new turbo will hold its 6-7 pounds all the way to about 7k rpm. The turbo feels like its not in its efficency range at only 7 psi. Im waiting for c-rad to fix me up a chip to take advantage of the turbo, walbro pump, and n60 mafs. Im shooting for around 240-250whp with around 14-15psi. I was told the turbo will hold together up to around 22psi.Once the chip is in I'll repost and let everyone how its feels with the 14-15psi I was running the stock CA turbo at.
