What did you use for your turbo Compressor outlet pipe? (j pipe)

 

The J pipe that came with the install kit + a 2.5" LICP with about 60* turn on it.

For future buyers of the 25g, just my opinion:
Get the 11.5 housing/ have it ported
Have the compressor housing ported to match the J pipe.
Get the billet wheel upgrade

 

I agree with rstchris. But, imo this turbo would be better matched with the td06hr 67mm turbine paired with kinugawas ported and bored 11.5 turbine housing. This kinda setup with a built top/bottomend, supporting mods and tuned for 30+psi should flow more or less like both the fpblack and ef4 stock frame big wheeler...


I recently bit the bullet and bought the billet 25g wheel and man. This thing looks amazing and promising both at the same time. Proven with all the bells and whistles. Extended tips, less blades with more blade area, smaller hubs, sraight egded and a 60mm inducer? Kamak did right with this thing. Im definetely looking forward too this transformation. Not too mention this is going In an old fpred ballbearing turbo cartridge so im hooing for some awesome results and reliability

My original fpred got chewed up (but the bearing housing was good and reusable) so decided too play with it. This 25g was exactly what I was looking for. Ima a mhi fanboy ( and I dont even own a Mitsubishi lol) but ive been plaging with mhi turbos for years. Had a honda powered by a dsm turbo kit and now my srt4 has been powered by nothing but mhi based turbochargers. No too mention iver rebuilt, custom made mhi stock frame turbos for many locals. Anyways, heres a few pics of the 25g/t67 billet compressor wheel. Notice how much bigger the wheel is next too my old fpred "60 trim" cw (56mm/76mm billet wheel). Its not as big as the black and ef4 wheel (well, the exducer that is) are, but im sure it will flow more as there are less blades and more blade area and better aero tech in these wheels than the others. Lmk what gou gugs think or if gou need anything answered or would like too see somethi gs as the wheel is not I stalled atm so I can easily snP some pics or something

^^ woah, that's a 60mm inducer billet wheel? It looks huge!

Mine is T67/t70 cartridge with a t67 compressor housing
63mm inducer compressor

Now I'm thinking, should I have gone with the Billet wheel?

 

Its a lil bigger than they advertised. Its more like a 61mm and the exducer is closer to 79mm. Its not as big as the fpblack/ef4 (the exducer on those wheels are 82mm) but, like I said. This should flow more.

Nice looking turbo :thumbsup:

Imo, you coulda forked out a lil more for the billet wheel if you have it. If not, this turbo shouk d still pack a powerful punch regardless billet or not. Kamak/kinugawa cast compressor wheels are already made too make more power and be more efficient as its counterparts. So I wouldnt worry too much...

Does look big though lol. Tbis going on your cobalt?

 

Yea that wheel looks huge lol, sexy as hell I might add.

Thanks bro, I'm hoping this wheel will do okay. Yessir, this is the turbo that will be going in my cobalt. I had an EFR 6758 (415whp/435wtq) in it, and it blew last month :/.I don't think this turbo will even come close to how that EFR spooled lol. Almost like stock! This turbo, I'm guessing maybe lag till 5k . I'm gonna need to build my motor and do some cams/valve work to make it spool quicker and make my rev limiter higher. I need to broaden the powerband from each way. I'm aiming for a cool 400whp on 91 octane 20 psi or so. I will be tuning for e85 and 110 mix as well hopefully hit 500whp on stock internals and fueling. Anyways, I might be coming down to SD in a month or two, I would love to see your car in action. Maybe even a little friendly comparo .

 

Ive heard lots of bad reviews about the efr turbo line up, but im willing too bet it was all based off speculations nah but that sucjs aboutgour turbo....thjs turbo will spool pretty late of its housed with their 10cm turbine housings but hooefully its not too bad...

Nice nunbers though! I never dynoed on oump gas since it was onky a baseline reflash too get me too the e85 fillup haha but I did dyno a couole months back with my old turbo (evo 9 stock framed 20g/td06sl2r) and @35psi, managed too make 534/510 on full e85. Car recently blew (dropped a valve and piston nunber 3 went chop chop haha) but the new build is near comete and hoping for a lil over 650whp with this new turbo and new build.

Ima message you my number but yea...if you come down too sd and youe all set too go, I coukd have us lined up for bragging rights

Not too .any big turbo cobalts around. Just evos, stis, cobras, vettes, bikes, cohple gtrs, few supras etc...but no cobalts...ive always liked them balts and have always wanted too play with one that was built/tuned. Maybe youll be that guy if were both ready too go..

 

Haha, yea unfortunately I was one of those few with the bad batch of turbos. They do wonders though, for a DD I couldn't have asked for a better turbo. Anyways I haven't installed the 25g yet, it should be here next week. My tuner is getting some machining done for it before it gets to me. I don't know anybody with a big turbo cobalt out here in LA lol. I'm probably the only one . I don't think I'd be to mess with you at 650 whp. Until I get my motor built and cams/valves I won't be able to go above 500whp. For now if we went at it it would have to be low boost vs low boost haha. Still nothing to sneeze at from two little 4 bangers making that much power.

You can check out some of my vids on Youtube, here is my channel.

+1. Hell even the TD06 65MM wheel would be tons better. It's unfortunate Kinugawa doesn't seem to offer those with a stock framed turbine housings for the evo.


better aero tech than the EF4 and FP Black? hmm. Not sure I agree with that comment. I seriously doubt Map or FP would sell themselves short, especially if an ebay turbo has it.

 

What makes you think these are "ebay" wheels and why would you say these fall short too map and fp? Id put money on it this wheel flows more than an fpblack/ef4....care too take that bet?

This wheel clearly shows proven technology in aerodynamics and blade shaping and im sure kamak (a leader in todays turbocharger engineering and much much more) has put tons of r&d into these new redesigned compressor wheels and im willing too gaurantee if we were too create compressor maps comparing the three wheels, these dual 5bladed wheels will flow more. All the wheels are similar sized inducer minus the competitors having a larger exducer (82mmvs78) and while this cw blades are much taller, less bladed, contain more blade area, and feature many of the characteristics already proven today with these new redesigned billet cw's, i dont see how you think my comments is anything but agreeable :idk:

 

talk is cheap. Show me a dyno above 748WHP with the 25g Kinugawa turbo.

I do not doubt they are decent and are a good cheap alternative out there. But a leader in turbo technology are you serious?
-They can't even make a compressor map or test their products on any serious platform
-They mate a 25g compressor wheel to a tiny 6sl2 that won't support over 50 lb/min
- They can't even post the right specifications of their wheels on their website

Really and they are leaders in turbo tech? Are you a salesman for Kinugawa or Kamak? Sorry but your knowledge of a few basic characteristics and your eye-ball test doesn't work for me.

I say prove it.

 

Kamak has become a leader in todays turbo engineering. You being in Japan should kno this as they are widely approved and supported on that side of the globe.

Agree, these billet cw's are a great alternative and I agree, they mismatched this turbo completely with that baby turbine. Imo, td06hr turbine wheel, or gtfo! :readclose:

No, im not a salesman, but im only pointing ouf the obvious and eye ball comparos between wheels may not look like much of a test, if that I understand, but comparing the wheels amongst each other, i can already dignify and identify the r&d put into this billet cw and notice flaws in the other two vs this wheel. For one, the blade area is much greater on this wheel meaning it will move more and pressurize more air, the exducer contains a much taller extended tip, the hub and the area around it doent take up as much as area as the other two wheels which isnt helping for airflow at all and doesnt make it any better than its casted counterpart, and last but not least, the taller, straight edge, dual 5bladed wheel has been proven time and time too flow more up top than its revisioned dual 7bladed wheel and the popular 11blade cw. Again, not a master in turbo charfers, but pointing out the obvious. Not knocking map or fp for that matter as fp os the bizzness hands down! But this cw is and sbould be the next big thing for the big boy stock frame turbochargers.

Please, dont be so biased and fhere will come someone soon that is going too make some awesome power using the 25g. You wait and see. Untll then, ill restrain myself from anything less than friendly but competive convo in all the same time from here on out till we get someone who will push this cw too its limits. But, dont be shocked when I say I tokd you so. Didnt mean it will kick the other runners uo for biggest stockframe upgrade, I know igs going too be pretty much near identical in air flow as the other two, but belive it or not, this wheel should flow more. But, were just going too have too wait and see.

 

Well said, can't wait till more people use the 25G and start making some serious power, my billet wheel should be installed some time this week, then is Dyno time and 42 psi on E85 to see what i can get out of it !

 

I couldn't agree more that this turbo "should" utilize the TD06HR turbine wheel but I am suspect it won't fit. Can someone measure the turbine housing and determine if there is enough material to cut out to acomodate the bigger wheel? If there is, I won't mind being the first one getting it done.

In the next couple months I will be getting the 11.5cm housing, having the housing and mani ported to see if I can open the obvious choke point a bit. I am also thinking about getting the turbine wheel clipped at least 5* too.

 

Now thats what m talking about :thumbsup:

Its a shame you couldnt have coupled the 25g with the td06hr turbine (67mm tw). The results would be much more phenomenal at the big of a boost setting. I still see this turbo making 550+awhp all day though. But, its just unevenly balanced with that tuebine wheel. I shoumd send an email and have them look into matching the billet 25g wheel witb a td06hr turbine wheel and the 11.5turbine housing. That screams 600+whp all day long with still room too make more...


I cant wait too see what this thing does in my neon once shes back together and the tuning can begin. Im hoping too be over 650 but id love too knock on 700's door. I know my turbo can do it. I know my motor can. Got the supporting mods and given im on a fwd platform, the drivetrain loss between fwd and awd should help me even more too compare my numbers too the fpblack and ef4. Once either one of us get the big boy numbers (meaning 600whp+) I guess then well finally get the right too brag and glorify these turbos. Till then, gators gon' gate and haters gon' hate...


Guess we'll just leave it at that haha cos I would hate too keep rambling on with an ending of me ruining the thread lol.
