wondering if this turbo is big and good enough for my engine? few people said its a lil small and some people told me its perfect. How would it be like on top end rpm's? if this turbo isnt good enough r there any other turbos off cars like audis, saabs, or volvos that i can pick up?

 

its not big and if its good enough for your engine is up to you. Is it in good shape?? If so i would use it depending on what kind of power you want from your kit. I would think you would have nearly full boost by 3500 rpm but of course it would lack the power of the larger ones.

 

yea its in great shape. the turbine has almost no play at all. i also have a skunk2 manifold, wonder how much that would help with the turbo. i was just looking at t3 turbos by garrett and the t3 is a lil bit smaller than mines but mines is a lil smaller than t3/t4. so mines is in the middle of t3 and t3/t4. so what do u guys think about the size?

 

well if thats the size then it should be good. For me i didnt want to go t3/t4, just a lil too big for me. Right now i am looking for a t28. It should be perfect. But if you already have the turbo and its in good shape id go ahead and use it. GL

 

thanks bro. any other opinions?

 

turbo off a old Tbird is a nice size T3

 

hows the t3 like on top end?

 

any inputs?

 

crap

 

that k26 is too small of a turbo it might not look that small but the housing is tiny you will hit boost early but loose it quickly

 

i use the t3 off the old tbird or thunderchicken sum like to call it, its works great has power all the way til about 6800 and i hit boost at like 2800-2900 amazingly and they are cheap to get from the j-yard i got mine for 80 bucks

 

i found the compressor map for this turbo . . . it's kinda small. top flow is only 28lbm/min. so if you're content with about 12psi max for LS or B17A or 9-10psi max for B18C, then go for it if it's in good shape. you won't be happy if it leaks oil or coolant or boost, though, so make sure it's nice or rebuild it. BTW, the K26 is about the same as most T3's, like thunderbird models and such. it fits in between the flow levels of the T3 50-trim and 60-trim wheels, with 3% less peak efficiency, so not a really big deal. and it's probably larger than a junkyard T3 as far as flow goes.

in any case it should spool up plenty early. i'd give it around 3200 or a hair higher for full boost, and hold pretty much to stock redline at said boost levels. note that going much higher than those boost levels will mean 2 things: aftermarket internals, and most junkyard turbos won't flow more than those boost levels anyways. you could take this one higher, but it will fall on its face up high in the revs. a nice intercooler will be required to hit said boost levels.

and don't forget to have your car TUNED WELL. that's the only way it will survive boost.

 

thanks for the input. just returned the k26 turbo and found a complete used kit for 1k. has a turbonetics turbo but it consumes oil so i figure bad seal. should i get it rebuilt or get a new one?

 

Actually, the K26 is quite potent. Porsche used it on the 951's and they had absolutely no problem keeping up with the 2.5 liter engines used in the same car. The K26 is also extremely similar to the turbo's used on the 930's as well. Despite the fact that it's relatively small, it is quite a bit more advanced than the T25 and the T3. Let's not even mention the number of companies that will rebuild this turbo with ported housings and a larger compressor wheel for those seeking additional power. The K26 really starts to die on the Porsche 2.5 at around 6400 rpms (stock redline 6000) so I really don't see a problem with putting it on a 1.8 revving to 8000.

 

ahhhhh im so confused now. some r sayin its quite small, some r sayin its quite good. im like stuck in the middle.

 

The T3 is a good turbo.

Just go with that.

Make it easier for you.

Yup. I had a t3/t4 on .48ar 60trim on my stock b16. Luved it!

i never said it was too small. like Kendall said, it's plenty potent. i just said that it is approximately the right size for a 1.8L with 7000-8000rpm redline as long as boost is kept in relation to that. keep in mind that 12psi on an integra with good tuning will make the car plenty fast, especially with boost coming in between 3000 and 3500rpm. this would be a great turbo for your car. i'm just saying that for some of us idiots, 12psi might not enough. but 12psi should be pretty much your dream car. if tuned right it can be VERY fast. like over 250whp fast. that's double what you're making now . . .

the T3 with a large trim is a good size for this engine, but that doesn't make it good. it's still an old design, although 75% compressor efficiency is pretty good even for today's standards. but with the K26 being slightly smaller than the T3-60T, i'd say the K26 is the better choice here, depending on exhaust housings and trims. if you want to push your stock engine to 15psi, the T3-60T or even Super-60 might be the better bet, although i'm sure the K26 could hold 15psi as needed, just not with quite the efficiency a large T3 could.

imagine if you'd had a turbo that was designed sometime in the past 20 years! it would have been even better!

word to the wise: don't get a T3/T4 hybrid unless you've got some aftermarket internals. they don't really sing until you get into higher boost levels, like 12-15psi or more, on up to 20psi or more.

Hey, i like my 20 yr old turbo. Alot better than spending $$$$ on a pointless bb turbo. And it was at full song @ 4500rpm 12lbs. Thats not good??

 

so if u had a choice between the t3 or k26 for 8psi on stock motor. which one would u take? and why?

 

ah just forget all that crap and get a Garrett GT ball bearing series turbo. the GT BB series internals are "20 years more advance"( read it somewhere) then the standard wet floating bearings

 

try the t3... i hear most people run the t3/t4 even on stock.

But if you want a real treat go find a old mercedes 900 turbo..

looking at a AirResearch t3 with almost a 60 trim on it!

 

i never heard of mercedes 900 ... do you mean saab 900?

The t/3. There cheap, reliable, and they boost hard. Sure there are more advanced turbos out there, but for the bb center, its like 4-5oo$ extra i think. I a mgazine i read( i forget which one) they did a test on a bb turbo and a standard on the same motor. Both perfomed well at lower boost levels. Only when your boosting 15+lbs does it start to make a difference. Dont flame me.......flame the magizine

no, i wouldn't consider that good. the T3/T4 itself is just too large. a properly-sized turbo for that application could be making that boost at 3500rpm, not 4500rpm.

and for the record, having a ball-bearing turbo isn't about slightly higher efficiency, lower spool RPM, or whatnot. it's about transient response. try a traditional wet floating bearing turbo. nail the gas and let it spool up. how long did that take? now try a BB turbo. garaunteed it takes practically a heartbeat. that's a HUGE difference. the downfall of turbos is that they have inherent lag every time you apply throttle, like in between shifts. a BB turbo will GREATLY reduce this downside, and hence should be worth every penny if you want to go fast.

it depends on the T3. if i had to pick against a T3-50T, i'd take the K26. if i had to pick against a T3-60T, i'd go with the one in better shape. if it was a T3-Super-60 i'd go with that. but really if this K26 is in good shape, get it. it will be fine. it's better than picking up a junkyard T3 that you have no idea what trims are in it.
