.42/.48 T3 on d16
Hello, i just bought a turbo that is a T3 .42/.48. I was thinking that this turbo might be too small for my stock d16y7. i know it will spool early but i don't want a turbo that lacks high end. Has anyone ran a turbo this size on a d series? what kind of whp should i be looking for at 8-10 psi?.
also, does a big turbo like a .48 at 8 psi put the same stress on the engine or less then a .61 at 8 psi. ?
thanks all.

t3 .42/.48 is a good size on a d series, at 9-10 psi, i have seen a couple that hit 180-200whp on a d16z6 and a d16y8, but not sure about how much it would with a d16y7
but if you want a turbo that doesn't lack on top end and keep on building whp, get a t3 60 trim .60/.48

T3s are great on a 1.6 sohc especialy if you got a 45 or 50 trim compressor. don't underestimate the exhasut, go full 2.5" or bigger. 10 psi feels nice but around 14 it gets really fun in a light car (maybe 220whp?). oh and port out the WG hole a few mm if you are gonna use the internal. good choice
The .63/.60 60 trim is what im gonna run for a little while. little upgrade from my current .63/.42 50 trim.

doesnt run out of breath on a d16 at all
i put down 185 whp with that turbo, at only 6.5 psi.</TD></TR></TABLE>
185whp with a t3 .42? thats what i'm lookin for. what motor did you run that on.
thanks for all the input fellas.

Re: (d0nfry)
185 is easy easy easy with pretty much any straight T3, its the 6.5 psi that's pretty damn impressive he must have had a larger 50 or 60 trim compressor im thinking.
You know the .42 a/r doesn't really mean **** right? its the size of the wheels that really determines the HP levels. The A/R is just used to kinda tune it between wheel sizes.
You could have a .82 a/r t25 that tops out at 190whp and you could have a .63 t3/to4e that maxs out at 400whp. Your t3 almost definitely has has what they call a standard turbine wheel in a .48 a/r housing. very common and works great on a D.
The compressor could one of several that are mated with that turbine. I know of 35,40,45,50,60 trim compressors on stock turbos. Basically you want the biggest you can find since the compressor doesnt really affect spool time and the bigger ones will make a little more power.

A smaller A/R will be more restrictive and will reach full boost faster but may choke the midrange/top end.

undo the 6 13mm bolts that hold the compressor cover and take it off. measure the small end of the wheel in mm and then measure the big side of the wheel and post it up and ill tell you what it is.

right but that only applies if you are talking about the same wheel, which is unknown in this case so its a useless spec. Read the example i gave above about turbine A/R. in that example a .63 A/R makes over 200 MORE whp than a .82 A/R.
Would you rather have a 60 trim with a .42 a/r or a 35 trim with a .60 a/r? If you want to make power you would pick the 60 trim.
A/R is not very usefull in determining the potential of the turbo, it jsut happens to be the only spec printed on most of them so everyone dwels on it IMO. A/R is basicly for tuning between whel sizes.

Re:
I'd say you put down about 185WHP at 9psi with after-market exhaust and 440cc injectors .. At least, that's how much Pollito from turbod16.com gets ..(he uses same T3)

my 185 hp was a result of lots of things. my brother built amazing piping, and a nice little high efficiency intercooler helped (small spearco).
2.5'' side exit/no cat/perforatedcore resonator exhaust also helped. d16a6

Re: (redzcstandardhatch)
t3's shouldnt lack top end if your running 10+ psi i know a guy thats gone up to 20 psi on a stock Y8 block Y7 head with arp head studs and a thicker head gasket...he's been running around 15 psi for over 6 months now...ar shouldnt matter that much...a t3/t4 at higher boost level though you might have a problem...

i will be running dsm 450's w/ aftermarket exhaust, and safc.
185whp is what i'm lookin for.
thanks everyone for your input happy V-day.

Ah, cool. I just did a pretty quick SOHC with a 45 trim t3, same A/Rs as we have here. I think he's at around 13psi right now, 3" exhaust, 880s (big plans ) It really pulls nice. i love sohcs with T3s

I was running a .42 from a saab 9000 on my b18b1 and i was running 13.2 at 11psi on a stock engine with fmu... spooled very very quick and pulled like hell to redline i loved that turbo,
