soon to be turbo b18c1
i have a kit sitting at home and just waiting to be bolted on, i just need the oil feed/return lines run and bigger injectors...it's set at 7psi with an internal wastegate. its already custom fitted for a b18 c1 in an ek... i have been doing some research on what kind of numbers i should expect... i found this dyno of a stock gsr, stock exhaust and etc with 10lbs of boost i believe...
does this seem realistic or close to what i could get? i am more interested in the torque it will make... how much torque would you need in an ek to really feel sucked back in the seat when the throttle is pushed? i am thinking like 180ft-lbs or so should do the trick? http://img157.imageshack.us/img157/2...norun24nf3.jpg ^^^^^^^^^^^^^^^ seems like a nice power curve too, no drop-off at vtec crossover as well... |
possible...but not guaranteed cuz every motor is different....you need good tuning to reach that with 7psi with stock internals....
i sat in an eg hatch boosted with little over 200wtq....it pulled me pretty good.....with that being said, if you love torque that much, get a viper=P...yes i am serious, that's one mean torque machine |
When I had my old setup, I thought I was pushed into the seat quite nicely haha. Well, maybe not....
I am sure you will get used to 180wtq quite soon, then you will want some more. There is no end to this. |
hp numbers depend greatly on the tuner and your set-up.
If you listed your set-up you could get a very, very rough estimate since we don't know what condition your engine is in or who the tuner will be. |
my boy had a bone stock b16, greddy kit, 8psi, 2.5" i/c piping, 2.5" dp flared to 3", 3" catback and he made 266whp and 18xwtq on a dynojet. to me 230whp & 179wtq for a turbo is weak sauce. there are b20v's making more hp than that and there are K24's out there making numbers very similar to the graph you posted. for me, i think i would need 350whp to be happy. because its not too hard to make 230whp all motor nowadays. its (n/a) expensive, and more reliable...but not hard.

i agree with m_power (like always)....230whp out of a boosted GSR is weak sauce.
I've seen stock b16s make 350whp....mind you that prolly won't last too long b/c it was at almost 15psi. Seriously mike, get your engine running tits before you put on your turbo setup, b/c that will only make troubleshooting even harder. And will increase the possibility of more problems/serious damage. |

If you listed your set-up you could get a very, very rough estimate since we don't know what condition your engine is in or who the tuner will be. set-up is as follows: well, as much as i know i am not 100% sure what all the parts are called.. turbo set-up -toyota supra ct 26 turbo 7psi internal wastegate -2 1/2" downpipe -2 1/2" charge piping/intercooler piping -24" front mount intercooler (5-6" width) -Turbosmart Vee Port BOV -custom turbo manifold engine/exhaust set-up -stock gsr (compression tested... 215, 215, 210, 215) -jdm s80 gsr LSD tranny -2 1/2" straight pipe mandrel bent (rsr gt2 muffler) -440cc injectors not sure if i am missing anything important. Also, i am planning on getting zeeman to do the tuning if it can be arranged around when I get it installed. |
it isn't absolutely needed, but i'd recommend a 3" dp and exhaust if you are aiming at 200+hp. that turbo is used to putting out 225hp on the engine it came with from the factory.
|
it might be a 3" downpipe, it looks bigger than the other piping, i just don't have anything to measure it... lets say its 3" for now.
|
im with aaron. Upgrade all your exhaust pieces to 3".. you'll get much better results.. especially with a ct26. Do you know what trim turbo it is?
|
nope... what is it?
is the ct 26 a decent sized turbo? if i am using my current 2.5" as opposed to a full 3"exhaust setup including the downpipe what could my potential power diferences be. won't there be more lag in the spool up time if i am running 3"exhaust? |

ya but mark thats at high boost levels..i know guys at around 200whp upgraded from 2.5" to 3" and they gained like 5-10whp. They said they couldn't even feel the difference.
But i would still upgrade to 3" because guaranteed, you will want more boost and better numbers. Yes ct26 is a good sized turbo, from what i remember they came off the 88-91 mr2's and supra's right? And yes a 3" exhaust will help spool time |
