ouch, 93 octane = Ping City...i was wondering if ne one has made 300whp on the jdmct26 turbo i juss got a 2nd gen motor and it has a blitz ecu and im goin to tune it on s-afc2 im trying to make 300 on 93 octane thanks..
thats what i needed to read, cheers for the link. sorry guys, im in AUS we have completely different ratingsWhen talking about octane you should remember that in Japan (and Europe), the "octane rating" of a particular gas is the RON measurement. The USA uses the average of the RON and MON measurement (hence the "93 octane using (R+M)/2 method" label on the pump) and since the MON value is always lower than the RON value, the "octane rating" displayed on a pump in the USA will be lower than that in Japan for the same fuel.
Without knowing the MON value for a given fuel in Japan you obviously cannot calculate the USA "octane rating", but I have heard others guesstimate that the 97 octane fuel in Japan is approximately equivalent to 93 octane fuel in the USA.
i know its off topic but the other thread is locked, can anyone confirm this for me? i remember struggling to find fuel cut even though i was well past 180kmh, doing multiple 200kmh runs i never found fuel cut. sorry to hi-jack.JDM speed limiter cuts in at 180km/h.
no not exactly, there are different versions of the ct26 out there supra single, sw20/celica duals etc. One particular person (board name doesn't come to mind...unfortunately) has a hybrid ct26. started with stock mr2 ct26, then fitted the supra exhaust side on it to get it some serious flow help. that turbo was never dynoed, but it pulled consistent 12s (like 12.8 i bleieve at 110mph?) the mph suggest he was putting out at least 270-280whp if not around 300.KoreanJoey said:^^^exactly^^^
stroker has "potential" to make more power, but many times don't. a stroker will cause decrease lag, so full boost is seen much earlier, but it falls off on top earlier as well. increasing the VE of the engine with the stroker, etc etc, the engine would be overbuilt for the turbo application. increasing VE is great so long as the turbo is capable of utilizing it to make that kind of power and have a nice flat power band near redline.sleeperneon676 said:I think its possible to get 300hp out of a ct26, someone did I just rea do nthe board. race gas, and the turbo wont last long. And you probably would need ALOT of engine work to do so...IE sstroker maybe? high compression and full BPU, weld the wastegates shut and have at it. But i would say 93 octane wouldnt do it.I tihnk youde end up spending alot more money trying to get that out ur ct26, then if you were buy a ats combo kit![]()
Why swap out the compressors why not just go for a CT27 just like you said. It still isn't a CT26 that came with the motor. It's like saying a T4 is the same as a T3. It's not.Boz said:no not exactly, there are different versions of the ct26 out there supra single, sw20/celica duals etc. One particular person (board name doesn't come to mind...unfortunately) has a hybrid ct26. started with stock mr2 ct26, then fitted the supra exhaust side on it to get it some serious flow help. that turbo was never dynoed, but it pulled consistent 12s (like 12.8 i bleieve at 110mph?) the mph suggest he was putting out at least 270-280whp if not around 300.
modified ct26s (by modified i mean the compressor changed, clpped the wheel, or whatever) i've seen as most as 250whp.
a ct27 can, however it is TECHNICALLY a modified ct26, there's been so much work done to them that they shouldn't be compared to the ct26 and it's in another category entirely. now this, hwoever, WILL put out 300+whp with bolt ons, romtune and race gas.
if you read my post over, not once in my post did i suggest that this hybrid is greater than all, in fact i even statedKoreanJoey said:Why swap out the compressors why not just go for a CT27 just like you said.

(however with a lilttle knowhow, it oculd be worthwhile if he didn't wanna fork over the money for a new turbo altogher). I was not stating that he go out and do it right away, i was giving him other options.Boz said:1400 ats ct27 pacakge and your done. or more with a tdo5/o6 package that would be capable of doing it on pump gas. plus the larger turbos would make that power level MUCH easier than the ct26 ever could
If you wanna make 300 hp on a car with a turbo that really shouldnt be pushed that far, you need to do everything to do the engine, like your building an NA. Stroker would help your peak torque which is what matters.Boz said:stroker has "potential" to make more power, but many times don't. a stroker will cause decrease lag, so full boost is seen much earlier, but it falls off on top earlier as well. increasing the VE of the engine with the stroker, etc etc, the engine would be overbuilt for the turbo application. increasing VE is great so long as the turbo is capable of utilizing it to make that kind of power and have a nice flat power band near redline.
but i agree with you about the cost tho. 1400 ats ct27 pacakge and your done. or more with a tdo5/o6 package that would be capable of doing it on pump gas. plus the larger turbos would make that power level MUCH easier than the ct26 ever could
Peak torque doesn't mean high power.sleeperneon676 said:If you wanna make 300 hp on a car with a turbo that really shouldnt be pushed that far, you need to do everything to do the engine, like your building an NA. Stroker would help your peak torque which is what matters.
"Same power" may be overstating it a little bit. you won't get nearly the results you hope for by increasing the displacement unless you can flow enough air to use it. You will flow marginally more, b/c now the pump is bigger, but will not be efficient, b/c the restriction remains. The stock head is a restriction on the stock bottom end. Enlarging the bottom, will only aggravate that problem.MR2000GTE said:Peak torque doesn't mean high power.
Making horsepower is about flow. A stroker with a stock head (stock cams/etc) won't make any more power than a stock motor. It'll just make the same power earlier.
