hey guys, just curiuos how a 60 trim 48 a/r will perform on my b17. Im hoping it will be enough to pull to 8000rpms before it drops off...how would its older brother, the 63 ar compare? Thanks... will be running 5-7psi on stock block...

 

Just got one for my sohc vtec. Haven't put it on yet. I'll let you know in a week or 2 when I get time to put it on.

 

it rocks for sohc's. i'd go bigger for a gsr though...

 

60 trim t3...does this look like a 48 a/r or a 63?

 

Kinda hard to tell what a/r the turbine is from pics....try looking in the turbine inlet, usually there's a stamp inside with ".48" or ".63"

 

i got the .60/.48 t3 on my b16, and it's baddass, spools really quick and top end makes good power all the way up to 8200

 

thanks for the input reaction... when does it start spooling, and how much boost are you running?

 

I used it on my ITR and it spooled fast but torque dies off at around 6500. I switched it out with an 82a/r and now torque pulls to 8500. I made 60whp just from switching out housings. The .48a/r on a B series is too small. The 63 or 82 are alot better. My 82a/r spools at about 4500 full boost at 5000.

Depends on what you want. I've driven a .48 and a .63 and like the .48 better....much more responsive and smooth power band.

 

.63 AR is just peakier, with more top end.

.60 trim T3 will get you to 300 hp,whether or not it starts falling flat on it's face depends on what boost you try to run out of it. 10-12 psi is probably the limit for B16/B17.

 

so if i wanted to swap out the 48 ar for a 63, where would i get one of those, and how much would they be?

 

turbonetics and other turbo companies sell the housings. i think they go for like $150 or something in that range

 

I need to change out my straight t3 for a bigger one. Would i be changin the compressor or housing to a bigger one or the exhaust???....its just a .42 .48

 

compressor housing or exhaust housing.....sorry guys

mine starts spoolin at around 3200 which is baddass..., when i drop 3rd on the freeway, it's instant boost. i'm runnin 10 psi. I've had it up to 15 and it still pulls hard.

although in my quest for more power, i may be putting a .63 exhaust housing on this weekend tho. i kno the spool will be a bit later, but i will achieve better top end.

i'd probably change out your .42 compressor housing to a .60 before you do the exhaust. my buddy has a .42/.63 on his sohc. spools at a nice gay rpm of 5500. haha.....so i got him a .42/.48 and the .63 is goin on my b16

 

see i dont know if i would just part it out, or sell the whoel thing in general and buy a whole another turbo...$150..thats like half as much as the turbo is! (hence..half of the turbo..get it?) anyway i'll let you know guys know how it plays out. im sure it'll be much more than i need seeing how im still n/a.

 

I just hit the dyno with my t-3 (.60/.42) on my b17. The torque starts to drop off at 6500rpm. It spools instantly. I make 20 more hp at 3000rpm and 50 more hp at 4000rpm than I did n/a so I can say it spools fast. I would say it's an excellent turbo for the street. It almost makes the b17 feel like a bigger motor instead of a turbo motor. I have a small t-04 compressor in my garage I might put on tomorrow just out of curiosity and dyno it again. I have low compression in 1 cylinder (130) so I'm screwing around with different set-ups before I re-ring it.

 

thanks othick- coudl you possibly post the dyno graph? what were the final numbers?

so does it feel like it dies after 6500 or just not as torquey... it'd be kinda weird not revving it out to 8000 (or 8500 like i do now)... thanks for your help.

 

I'm sorry I don't have my scanner hooked up yet. My #'s are 207hp and 164tq at 8psi. It should have been around 220-225 but my car goes super rich around 7000rpm. So rich in fact that it began to miss at about 7500rpm. My peak power came at 7000rpm then nosedived, you could see clouds of black smoke coming from the exhaust. I wanted it tuned conservative but I guess I went a little too far. I will go back and use the wideband next time and get it all tuned properly. I think the torque dropping off around 6500rpm is pretty normal for smaller turbo's like the t-3 but it still pulls good to 7500rpm, with a little tuning my car should make good power all the way to 8000rpm. I like to start out conservative with my tuning and slowly get more aggressive with it as not to blow up my motor. I'm pretty confident the t-3 should pull good to 8500rpm on your car. Once I get my scanner going I can send you some dyno plots. My car should be all tuned by next week.

 

othick- please keep me informed--


what other mods are you running as far as manifold, management, block all that good stuff...also what is your vtec set at, does it really matter?

 

im just curius if i should sell the 48 a/r all together and just buy a 63 a/r... i wanna daily driver, but i cringe at the fact that it'll be dying off around 6500 especially since i'll only be running 5-7psi... any opinions?

when does (would) an .63 a/r start to spool, and would it pull to 8000 ya think?

 

its nearly impossible to say when the 63 would spool for u. each motor is different, and each turbo setup is different.

I know u imed me about this, and my reccomendation was to try teh .48 and see... but now that i read ur post more, i think maybe u should just go for the 63 off the bat.

 

also, i see no one has asked this yet.. whats your horsepower goal? PSI shouldnt be teh goal, whp should.. 10 psi on a T3 like this isnt the same as 10 PSI on say a T3/T04E hybrid

 

I want to disagree and say try the .48 housing before you bust on it. My .48 housing on my d16 spools fully at like 4000-4500rpms and it only "rips" from vtec to redline (5000rpms tires break loose) and it pulls so hard past 5000 to redline that from first to second it's almost hard to mkae the shift in time. It feel like MY motor wishes it had another 1000rpms to work with, so try the .48 before you go .63. I wihs you guys could try both-- but the .48 housing is by no means TOO small for a b16. for a b18 i'd say maybe... but for a b16-- try the .48. you wont be unhappy-- more area under the curve!!
