hey i currently have a 98 gsr-t i made 255 whp at 12psi, i have stock internals, i currently have a Mugen twin loop that im selling which is 2 1/4 inch piping, im switching to a 3'' down pipe and full 3 inch exhaust...and re tuning, how much power should i expect to gain? thanks

 

probably not much mroe than 10 or 15 hp

 

really do you think its worth selling the Mugen then?

 

I would upgrade to a larger exhaust to reduce the back pressure

the larger piping will improve your spool time, reduce some lag, and free up some extra horsepower the smaller exhaust piping was holding back

 

ok then it seems worth it thats what im going to do

 

Its defintely worth it. How much you want for the mugen twin loop?

 

what kind of turbo do you have, that you're only making 255 whp at 12 psi? is it a t25 or something?

 

its the 18g full greddy kit, im thinking about doing a small build and going up to a ball bearing t3 t4 but idk well see the car is so reliable now which is why i like it....

have a buyer with money in hand offer 700, and hes local, so at this point some one would have to beat that and be willing to pay the 100 bucks or whatever it is to ship...which would still be cheaper than new...but the buyer is just waiting till i get my new exhaust on.. so just let me know

 

More info on turbo setup. I'm interested in this...

 

buddyclub spec II


...its 2.5 so pointless if you want 3 inch piping.

 

theres not to much more info to give on the turbo set up, its just the basic 18g full greddy kit......with greddy profec b boost controller and greddy remote boost control button...

yeah and im not doing anything but 3 inch otherwise ill keep the Mugen, but it looks like im going to do custom 3'' piping and then a major shop hear in tampa LHT Performance, makes 3 inch mufflers that look exactly like a stock type r but are nice and quiet until you get on it, or i might get a thermal muffler, i can basically use any 3 inch muffler but i dont want it to be really loud mainly because cops here a are rediculous, and write exhaust tickets right and left ( even though we dont have emissions in florida!)

pretty much. the stock greddy downpipe is so dinky, plus i was using a 2.25" cat as well. I've seen full 3" exhausts, from the turbo back, make 50whp on the greddy kit, after tuning.</TD></TR></TABLE>

so that 3inch downpipe and full 3 inch exhaust make 50 more whp

seriously? haha thats hard to believe but would be nice!

 

yeah i got that out of the db thread so im not sure if this is dyno proven or not but anyways good look!

you should dyno right after so everyone cna see your gains

 

i am i will post results

 

thats some low *** horsepower for 12psi.

 

you clearly dont know ****! 12 psi on a stock internal gsr motor is about as much boost as you can safely run, and on a greddy 18g turbo kit 255 is normal cause that turbo about maxes at 300 to the wheels......the only reason its safe to run 12lbs is because of how small the turbo is, i have an idea talk to me when you know something jack ***

apparently you dont know much. psi does not matter. you could easily make 300-350whp on stock internals with the right turbo and tuning. 12psi on your 18g is not the same as 12psi on a gt30.

I realize that! my point was with him he was talking **** about me have low horse power at 12 psi and my point is that with my set up which has been clearly advertised that is not that low, 12 psi on my turbo with stock internals, is alot, and i still would stand strong that even witha bigger turbo if you made 350 with stock internals you would be an idiot because your motor would explode...

 

wow, i like your horse power and tq difference. i only have about 20 lbs of tq than you but i have 349hp.

people are making over 400whp+ with stock motors.
is all in the tune.
it seems that you dont know ****.

like others said, 12 psi doesn't mean ****. it all depends on what kind of turbo you have. the bigger the turbo, the more air it can move at the same pressure. anyway, isn't the greddy kit supposed to make around 250 whp on a gsr with the regular pressure (~6-7 psi?)? i would think a greddy kit at 12 psi would be closer to the 300 whp mark. what're you using to crank up the pressure? is it tuned?

have you heard of tuning? it's amazing what the right tune can do for your engine.

 

i would like to see a 400+whp COMPLETELY stock motor (internally) that is daily driven with the reliability that blkgsr-t is looking for...
