running a t-25 on a ka24de, is it worth it??

[AceInhole]

Truthfully, i wouldn't recommend running the T25. I'm only using mine as a way to get the new manifold and downpipe on the car since my current setup is cracked in half, literally. The turbo i hope to end up with is a GTiR T28 or a GT25R (yeah... big price differential :p).

The TD05 i used had a 12B compressor, which is SMALL. I measured it to be a 45 trim wheel with a 1.6" inducer. The SR compressor is a 60 trim IIRC.

[Xren17]

I saw a TC05 on on ebay for pretty cheap. What do you guys think of the turbo because I can't find any info on how it compares to a T25 or T3.

[MikeMurphy]

Interesting numbers. Some other guy on here ran a T25 and was only able to get 155whp at 6psi or so.

weird. T25 isn't that inefficient. at least, the SR one is trimmed well. Maybe he used a z32 T22 (commonly mistaken as a T25) or a Mitsubishi T25.

[raging panda]

Yes ace, thank you so much. I just got a mitsu tdo5-12a for free that im gonna rebuild and be using on my KAT setup, only gonna be boosting about 6-7 psi. You are my hero.

[AceInhole]

FWIW: the volvo housing on the TD05-12B seems to be better than the one that came on the starion (12A). I'm not really even sure the 12A can sustain 7psi to redline.... but if it does you can bet it won't be very efficient. A good intercooler is going to be your new best friend.

[AceInhole]

Just had my first drive with the T25 on the KA. IMO, as long as you've got a VERY good intercooler.... this setup rocks.

Nice Mani Ace, build it yourself? Whats the line under your MAF?

[AceInhole]

Line under the MAF is the recirc for the BOV.

Dyno'ed today.

with the TD05-12B on a log manifold:219.9 rwhp 251.4 rwtq (SAE corrected)T25 with ss autochrome manifold:233.0 rwhp 267.7 rwtq (SAE corrected)[

sorry, scanner isn't working.

Video can be found here.

Looks to me like a GTiR T28 would be perfect.

[dareo]

cool! if only SS autochrome would make KA manifolds, it seems they are pretty close with the SR manifold. I'd buy one.

[AceInhole]

they do make KA manifolds. they just cost over twice as much.

[WDRacing]

What boost are you running?

[AceInhole]

8psi to 10psi depending on the run. 10psi it falls back to 8psi anyways.... need a better boost controller.

[14.5drift]

Damn you aceinhole. Those are fantastic numbers.

[AceInhole]

i need to fix my intake piping to be slightly more efficient. my problem now is getting the turbo to keep boost up over 5000rpm. if i can do that, i'll raise my peak by like 10whp or so. Really need a T28, though. It should keep the same lower end power (relatively) and still flow well enough to make like 280 at the wheels. Maybe more with a bit of head work and playing with the cams more.

[AceInhole]

By the way.... all this is on the hacked MAF.

[14.5drift]

Hey ace, how would the td05h compare to the t28? Reason I ask, I plan on putting a greddy kit on at some point but will likely swap the 20g out for the td05h. Too small? Maybe 18g? (feels stupid cause he still can't read a flow chart)

[AceInhole]

TD05H refers to the turbine wheel, and it's slightly larger than the T28's. The 20G compressor wheel is fairly large (at least, from my knowledge of standard mitsubishi turbo's), as is the 18G (which is smaller than the 20G). Your questions sort of don't make sense since the Greddy kit comes with a TD05-20G. The TD05-18G is smaller than that, though a 16G is what I was going to use before I swapped to the Garret stuff.

[14.5drift]

td05h is the 16 gauge found on the evo VIII. Considering it puts out nearly 20 psi to the 4g it should be capable of 10-15 on a ka, right? If not then maybe a 18g? This is what I was asking. I have no use for the 20g so I would be swapping to the smaller turbo in exchange for the better response.

[AceInhole]

16G is about the same size as a 60 trim T3 compressor wheel (actually a bit smaller). Conversely, the TD05 exhaust wheel is slightly larger than the T3 exhaust wheel. Also note that the T28 uses a T3 compressor wheel (I plan on ultimately using a T28 turbo).

To put the Greddy kit's 20G into perspective: the 20G wheel is about the same size as a T04B wheel, so Greddy is basically giving you a T3/T4 hybrid- like turbo. Pretty much the generic "best" turbo for the KA.

[BomexS13]

how much did you spend on your setup Ace?

[AceInhole]

i got no idea now..... been through 2 KA's, 3 turbos, 3 intercoolers, 2 manifolds, 2 downpipes, 4 oil lines, and god knows how many ic piping setups. i'm guessing like $3000 including a new engine.

The "little" things just keep adding up, don't they? :pface

nah, it's mostly because i drive so much. i average over 40k miles per year. I also beat my car up a lot. Last season I competed with 3 different autocross groups, with at least 1 other co-driver (3 for some events). The car has seen the equivolent of maybe 40 - 50 autocross events in just one summer.

[AceInhole]

oh yeah, might as well update: I redid my hotpipe and cleaned my airfilter (it was CAI'ed through winter... was virtually CLOGGED). I've gained about 5 - 10% more airflow than what I dyno'ed with. It holds 8psi much better now. Not gonna dyno again untill March 20th though. If it weren't for valentine's day.....

[hayato kazami]

where did you get that manifold??

[AceInhole]

ss autochrome manifold for the SR, refit with a KA flange.

[WDRacing]

You might want to use a vacuum can to assist your wastegate. We did that on a guys turbo dodge van. Without the Vac can it wouldn't hold over 12 or so.

[AceInhole]

i've got a manual boost controller. it's ball and spring, though. just need to add a boost trim controller (bleed off valve) and it should be better.

i think the increase from the hot pipe swap is good enough, though.

[hayato kazami]

are you refit it by yourself? by the way, where did you get that KA flange?

IT IS VERY NICE! so i guess from now on KA owner can just get a SR turbo kit and then refit the flange.... ^-^
