i thought you had a 2871 waldo. 400whp on a 2876 takes a whole hell of a lot.

 

Eric has a 2871 and seems to be confused, this guy is talking about the 2876 not a 2871, and you apparently are confused also, 400 on a 2871, not done all that often, 400 on a 2876 will be a little bit easier to do.


From what I remember when researching each of them, I believe the 2876 uses the turbine wheel thats supposed to be in the 3076R but machined down to fit in a T2x housing, so it isnt all that great.

Im sure however that you'll be able to do the 400 you want on it. Though if I were doing an SR for numbers around there it would probably be a 3076R bottom mount on the stock manifold, with the TiAl exhaust housing they make which allows you to stick a tial 44mm gate right to it.

 

haha yea waldo moment. my bad


and tommy there are a couple guys making 400+ on the 71, yea its not the majority but its more then possible was all i was saying.

 

Yup I know its been done I was just saying thats not the norm, if you somehow are set on 400, get something just bigger.

 

yup yup.

 

I didn't think that there was room for that, with it being close to the strut tower. I was thinking about this yesterday.

2876 shouldn't have any issues making 400 on an 86ar housing. They make a bottom mount 3071 in a T2 housing that I'd use if starting from scratch, though.

 

Im pretty sure there is enough room, I peeked around a bit, heck worst case you could put a 90* right off the flange and locate the wastegate where you want.

The nice thing about it is that im pretty sure it doesnt require the cut down wheel, I believe the 3071 and 3076 come with the 60mm exhaust whee, and the 2876 and 3071 with the T2x flange have that wheel cut down to a smaller size to accomodate the T2x housing.

 

thanks guys for all the responses

 

Yeah? You want to lose 60hp right off the bat?

Being that "log manifold" is listed in their modifications for the before test, I doubt they were using a stock manifold. You do also realize that test was a GT3040R right ?

82mm 56T compressor, at 13 psi, on little cams, a 600HP turbo, at around half that power, gee this sounds like an awesome comparison.

GT2871 @ 15 psi doing 353 RWHP, but that 3082 only did 300 rwhp at 13, riiiiiiight GT2871 USERS. SR motor - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

If you believe the story they are sellin, thats cool. But i'll pass on that load of BS
