My 1992 B13 SE-R Graph



I made 143.9whp and 130.3lbs/ft. of torque at 5800rpm. My torque band peaks out at 144lbs./ft. @ 5300 rpm. Is there an explanation for why this is? My mods:
CAI with HKS super Mega-flow, Hotshot Gen. 3, Magnaflow muffler, and timing advance. The ECU is stock. Mobil One was the lubricant and I had BP 93 Octane Gas. Let me know what you guys think. Thanks.

dudes those numbers are hard to believe for me, I've got and SR20DE highport red top engine eGT trim, i put the S3 and headers and all 2.25 free flow exhaust system and the difference from stock is very very small i think something is wrong or just those numbers are not correct i run the car with some advance timing and 100 octane fuel, the engine is about 20k miles on it :confused: :confused: :confused: i don't have dyno number but i think its no more than 130 horses on the wheels or may be less :confused:

try changing your fuel pump...or check if the fuel pressure is where it should be.. if you have the air+petrol=power! lol.....

check your timing or put your car on a consult to check if there is any errors...

N15 Nissan Pulsar. 108.3kw = 145.2hp atw. Keep in mind that this was a rolling road dyno, and dynos here in Australia read a little lower than the US variants.

Mods are: Pod filter, standard intake piping/resonator, JWT C2 cams, Supertech dual valve springs, Ti retainers, X-force extractors, 2 1/4 mandrel exhaust, hi flow cat, offset muffler, Fidanza flywheel and a PLMS daughterboard (aussie equivalent to Calum basic board)

Today I went over to Hi Tech Motorsport for a Dyno test & rolling road tune i.e. fuel pressure and ignition timing optimised. Yes the gear he uses is old, however my engine is old too.


Been here a total of 4 time now and each time I could not fault the readings. Then with the NPOC (G20 chassis) chaps DE’s with I/E/H made around 135 – 140whp the same over the UK for same tuned SR20DE’s


Engine mod list

MIJ 2.25'' stainless steel mandrel cat back
Edge Racing 2.5’' resonator decat
Tomei Poncams 260' at 0'0
ASP 4-2-1 header with 3’ downpipe
2 piece UR lightweight pulleys (ran out of time to fit the PAS)
FSE fpr set to 4bar
PiperX panel filter with cold air feed
2.5’ induction hard pipe kit
Magnecor KV85 HT leads
NGK Iridium spark plugs
Ignition timing at 19*
XTD prolite flywheel & stage 2 clutch


163whp @ 6400rpm & 180lb ft @ 5400rpm

not quite the 200bhp mark, its 196bhp @ 6400rpm with ignition timing set to 19* and fueling set to 4bar. It was 192bhp @ 17* ignition advance, however at 19 there gains everywhere.

hypothitcal situation:

power mods:

Outlaw Engineering Thermoblock Spacer
Timing to 19*
all 4 UR pulleys
2.5" SSAC header
2.5" mandrel bent exhaust
WRX STi muffler
ghetto CAI mod
K&N Drop in Air Filter
JWT S3s
JWT ECU Flash for S3s
JWT motor mounts




I would expect that set up to get about 155 whp on a good day from what I've read.
If I went with JWT S4's and a JWT ECU tuned for S4's, what would I exect to get? 165 whp? and how would the torque curve look? I'm tired of searching!! ;)

I think you shold be around 145whp+, how do you fit the WRX muffler into your car???

Also.. try using a cut-out, it would help specialy when you have aftermarket cams...:biggthump
