my new project

^I know a guy selling a S400 turbo

Okay cool. Would you mind getting me details on it? Like price? Is it the standard or race comp cover? What compressor wheel? Exhaust a/r

I need the standard cover with the 5in inlet and would prefer a 67mm or 71mm but might consider bigger if the price is right. You can pm me if you don't want all the details in the thread. Thanks!

Just for comparison sake, here's a pic of the BW .88AR undivided T4 housing (left) compared to a T67 .68AR T4 housing (right).

The AR numbers aren't really that much different, but remember AR is just a ratio of Area to Radius, so the numbers can be a little deceiving. The pic makes it pretty clear how much larger the housings are and how much more air they flow. The "R" is obviouslly way bigger, so the "A" must be much larger too.

I wonder how thick those housings are?

[4seasons69]

Hmmm I wonder how their .90 or 1.00 would compare to my gt42 .91. From my understanding from the research I've done the housings are very similar in dimensions to my gt42. But maybe they were just talking about the comp cover and not the turbine housing. I'll have to look into the dimensions more and make sure it will fit

Are you going divided? There have been tests done on the divided housings showing that the "smaller" .91 housing made just as much power as the one 1 size larger, yet improved the spool. That is why I got the .91. Then once I realised the housings are massive, and the number is a little deceiving, I understood why. I think there is a divided one in the .8x size range, I've been contemplating switching to that.

Lots of really good info here:

I'll have to check my exhaust manifold and see if that is divided or undivided. but will probably go with a divided either way lol

Well I got a little work done today.

Some more pics

Well I got the long block assembled and ready to have the cams degreed. Now I just need the cams degreed, clutch rebuild kit and an upgraded clutch fork and the engine can go back in finally.

Also when I was going through my parts I found my oil pick up tube but map had already put on my oil pan. I figured map probably installed a new one but for my own peace of mind I pulled the oil pan and of course they did but I snapped a picture of the main girdle

That's a pretty shortblock
