Goal DD with ~ 310-330rwhp. The IS300 is a virgin block with an eshift tranny and I do not plan on swapping out HG at this time. Hope to not go that route so the build is pretty conservative w up to 7psi. Car won't be race nor drag. I when it's done, I probably either have John Reed (if he's still around my area) or KOracing tuning it.

So looks like i'm going forward with the build as I just picked up the comp ct4 6065 triple ball bearing.

I probably need a lot of help making a parts list here.


Parts acquiring:
I originally wanted a pte 5862 then to 6065, but couldn't find a used one anywhere as it is expensive new. I ended up getting a ct4-6265, just hope that i didn't make a bad decision on this. The turbo had 500mile and 2 dynos per seller. I'm thinking it might actually be a lot more miles than that though.
http://compturbo.com/products/turbos...illet/ct4-6265 T4 divided housing with .70 A/R. A/R might be too small but it might actually help spool as i'm only running .5bar. Any speculation on how much lag I'll have, and torque + HP range.

Of course don't forget about 300ft of wiring for the ems. Dammmm... I'm planning to run the EMS inside the glove compartment ~ 13 - 14ft x 22 - 23 wires or so.

This shoud be pretty easy to read.



Let me know if i missed anything else.

 

Looks like you have a pretty solid build going on.Not sure about the DP and IC kits but just be ready to have to modify a bit to make it work with your setup.I ordered my manifold from SRT cause surprisingly enough there only around 400 shipped and the quality is nicer than the ebay ones,if you go with the ebay manifold just have some of the welds reinforced and you should be golden.I read on MY.IS that one of the ebay intercooler kit works fine(http://my.is/forums/f114/my-ebayish-turbo-build-459274/). You'll have to look at your wastegate as well to see what dump tube you'll need.Definitely consider doing headgasket and head studs cause while your internals will be fine I wouldn't run over 7-8 pounds on factory headgasket.

 

DAMMMM dirty bugger

I might get the T4 housing coated before installing it.






Turbo had no shaft play at all, and spins extremely smooth compared to a brand new Garrett GT25 I had 10 years ago.

 

received most of my parts today, still waiting for the fuel pump, an oil restrictor with a .040" orifice.

 

I was thinking of ordering a ebay oil feed and return kit did you get one ? Or opinions also how did your turbo install turn out I'm doing a similar godspeed kit on my 99 gs300 on stock internals.
