ok guys i have decided to go with the t28 tubo of a s15. as my mate is upgrading his s15turbo so i will get the t28 for cheap... i was just thinking about a decompression plate? any 1 know much about them? would i get more power with 10psi on high comp compared to 14psi on low comp?? and what kind of power figures should i be expecting with the t28 on 10psi?
thanx

I would not touch compression.
No Decompression Gasket:
Good combustion
More responsive
Good fuel economy
Less boost : low heat
Yes Decompression Gasket:
Bad combustion
Less responsive
Bad fuel economy
More boost : More heat
But as always it comes down to your setup, install and tune. If anything is crap you be the 1st one to find out.
dude get the ball bearing t28r, trust me you wouldnt want to get a non ball bearing turbo you will regreat it turbo lag sucks. dont forget you have to do your injectors and get a tune.
planz changed and never got around 2 turboing the dc2...
now driving a 180sx with a gt2871r 0.86..
i definatly wouldnt recomend a massive turbo on a honda tho. its useless. you will have huge turbo lag, and unless your boosting to 17psi min your not in the efficiency range. and i doubt many ppl will be doing that here as your all high comp.
wtf?
1. run a biggert turbo to get a bit later boost = more traction on fwd
2. Honda motors like to flow much better than the sr20 etc etc so no matter what the turbo will come on boost earlier
3. More cp = less boost to reach a similar if not more power goal = less heat
bla bla bla.
for a stock b18c id look at a gt2871r built internals something up around a gt30 maybe 35 on the smaller side of the 35's. then there are other turbos too not just garrett.

I know this turbo. Its stupid. it boosts so late on an SR and doesnt even make the power to back it up. Friend had the same setup. I guess its the whole fact its T28 based. All the nissan guys are scared of the T3 framed turbos. Just for your information, switch to a GT30R and u will gain middrange, and massive topend!
the 2871R was designed for twin applications. Large bores.

yeah your right the .86 has way 2 much turbo lag if your not planing on running more than 20psi. the gt30 .64 is a better option but reason i didnt chose that is because i would have top go high mount of the 180, which would get me defected in 5seconds,lol but im pritty happy with the 2871,, but should have chose a lower rear aR.
