Okay so does anyone have any prior knowledge on a 16g turbo? I have it more availble to me cheaper with a manifold read for it then i do the t25. so worth it? on a stock block? I also am thinking of a block mini build also maybe so. idunno yt, any suggestions welcome.

 

A good alternitave to a wide band is an EGT guage. Hot means you're lean, which is detonation conditions. A wideband would still be your best bet. This place has good, cheap guages. I know that these work http://prosportgauges.com/

 

Hot means you're either too lean, too rich, ignition is too far retarded, or ignition is too far advanced. It's not a viable tuning gauge by any means unless you really know what you're looking at.

 

I was under the impression that unburned fuel from a rich condion would cause a low EGT. I also thought that running your timing too advance would cause a lean condition, and thusly a high EGT. Either way, a sudden spike in EGT means something just FUBARed and you need to pull over. Wideband is still the way to go

edit: I didnt mean use it as a tuning guage, I meant it as a warning gauge

 

Okay so heres some more questions for you guys.

This turbo manifold. whats it for? It looks to me with soem research to be a t3/t4 or a t25, but i can't figure it out.


I realize its gotta be something with an internal wastegate, but you guys got any ideas?

and is this thing worth saving i'm pretty sure its a fuel pressure regulator, but it hs no numbers on it anywere, will it coem in handy ina turbo set up?

 

BUMP. any help? no?

 

Okay fine, thanks alot guys, lol. im researchin 24/7 here. thought maybe you guys could help lessen the load.

 

Looks like a T25 manifold, cast at that. Problem is I can't tell for sure, the T3/T4 and T25 are different flanges but they look alike.

You're better off asking whoever's pictures they are what the mani is for.

No, you don't need the FPR.

 

Thanks sov, the thing is is that the manifold is mine and i took the pictures, and the guy i bought it from has no idea if its t25 or t3/t4. I'm leaning towards t25, but i have no idea. I guess the only way really to tell is to attempt to slap one or the other too it really?


Also, turbos off ebay? Even if not name brand. like this http://cgi.ebay.com/ebaymotors/T3-T4...mZ200201288486
At all anywhere near decent. I know name brands are better but yeah?

 

^ if it was me, i WOULD NOT get that turbo off ebay. It looks like gneeric shiny ebay sh*t to me
