yeah, real clean..... :rolleyes:

is it a gt4294 or 4202?

journal bearing? I dont see water lines.

btw, heres mine, a little closer to clean....

I get sick and tired of it too. Like was stated before he is on a budget and he did the best he could with what he had. If you don't like something or want to make fun of somebody then just keep your mouth shut. We aren't all fabricators or have the funds to make things look perfect.

Dude the kid is on a budget, with very few fab tools, wanted to try running this as a single turbo, just trying to do the best he can. Why pick on him? I get freakin sick of everybody on here critisizing anyone who does something thats not the popular choice, some people just like trying things. By the way yours does look nice, what turbine housine is that?

I'm on a budget too, i sold my 66, bought the s400, and everything to put it on, and still had money left over.

im all for throwing something together. if your gunna do it, and hack it, thats fine, i'm all for whatever work, but dont say its a clean install.

its a 1.10A/R housing.
 
so why isn't it clean should i go detail the motor then take pictures would that be considered clean just wondering
 
i dunno, the coffee can welded to the vband flange, welded to the down pipe. The 3.5" v band compressor outlet w/ the 3" OD elbow welded into it. Or the 5" to 4" to sewer pipe to the stock wrinkle hose for the inlet.
 
you could get it to spool quicker if it is a divided (twin scroll) exhaust housing by using an actuator operated block-off door on one of the ports. It closes off one of the ports so it turns a 26cm exhaust housing into something like a 13cm exhaust housing and then once you get past a certain psi, the door opens to relieve excess back pressure and help the turbo flow much more in the high boost levels

Does anyone have any input on weather these actually work without costing any hp up top? An interesting idea especially for us big single guys!

Actually, now that I think about it, wouldn't this just shut off exhaust for half the motor when using a divided manifold which is obviously a bad idea?

YES! Not good.

You would have to modify the exhaust manifold to allow both cylinders to flow into the single port. It would be interesting to see. I don't see it taking a 26 down to a 13, but I could see it helping spool up. What kind of costs are they?
 
well, you can always "undivide" your manifold with some porting or you could use a spacer. This works very well and many 2jz-gte supras (3.0litre) running 88mm turbos use these

Next thing to think about is heat. I don't think a supra puts out 1800-2000 degree EGT's either does it? Woudl be interesting to see.

Are you saying you think broken/melted shafts and butterfly valves in the turbine housing are a bad thing:hehe:
 
Data has shown that a valve will increase spool time by approx. 500 rpm on an LS1 with a s475 single 1.32. with no loss in hp. I will have to find the graph again...

I am planning on trying one under my s362 .91 and in the hot pipe before my s480.

Or my hy55 vgt single....

to many options.

You can get them on ebay for 160.00 from performance metal works. but you have to make your own actuator. I think 250.00 complete with actuator.

both t4 and t6 are available.
 
Well they are certainly interesting enough. Anything that can be done to get big singles to spool faster is a win win!!!

In my experience, a gasoline turbo motor will typically generate hotter exhaust temps than a diesel motor will. The max EGT number that we would try to stay under with the gas stuff was always ~1550 degrees F. You could easily peg a 2000 degree pyro with a car that wasn't set up right. Cruise temps were typically in the 1500 degree range as well.

That's what I was gettin' to....
 
i have no problem spooling the turbo especially now i just put full cuts in im going to try a smaller housing an maybe bigger lines
