I am less than not impressed.
reds and blacks make 300tq at ~3900
this snail hitting 300tq at ~5200

 

I'm pretty sure there is a large difference with exhaust turbine housings between the two. You can change the exhaust turbine on the 25g and I'm sure it will peak torque much earlier.

 

Maybe this is true but I saved over $1000.00
And I can take that ex tra savings and do a lot of things with it
Take my wife out to dinner ten times
Buy my kids something......
Thoses are great numbers....
How about wow good numbers

 

The new TPS corrected my issue. Tuning now. I'll try to get to a dyno afterwards.

 

It pays to know the full story before making statements dude, i already stated this is my old turbo which had an external wastegate on the dump and the twin scroll effect had been eliminated therefore we got slower spool which equals less torque, i've already tuned several of these and both torque and power are on par if not better than other FP equipped Evos i've done, and for $1,000 as compared to $3,000 for an FP i can deal with the lower torque if that was the case.

 

+1^

 

Installing and external gate on an internally gated TS housing is about as dumb as it gets. but even that has been shown to slow spool by only 700rpm. This turbo is no where near as enjoyable as an FP turbo. you are miss leading readers to post that crap. I have seen about five graphs on these 25g setups. They all spool horrible slow. There arent worth the coin if you ask me. But if savings is such a big concern for ya then have at it. I could care less that you car is not as fun as it could be.

 

Why are we comparing turbos? Should I bring up an EFR and state that FP is not as enjoyable as an EFR... Cmon man. What is horrible slow spool for a turbo that's the size of a gt35r. I hit full boost at around 4.4krpm and power will not stop climbing. If you can care less, then why troll and post.

 

what would be better buy the whole 25g from kinugawa or just get the housing and the 25g billet whell and install it to the stock 9 turbo and balance it ?

 

Ive got a td05 wheel and hit 23psi at 4000. These turbos spool. Trust me. Oh and cast comp. not billet

 

I compare the turbo to FPs because it has been brought up by guys using the 25g that it is a good alternative at 1000+ less. I say it is a sore alternative and wouldn't dare stoop to using one. The compressor wheel is 35r size. 35r and FP black are making 700whp. So why the rave about this 35r size turbo making 550whp with worse spool than a 35r?? problem is this turbo has a turbine wheel the size of old school greens, BBk and the like 450-475hp turbos. this is part of the reason no one can get this turbo to work well with the internal gate. theres too much back pressure blowing the gate open early and ruining twin scroll spool.

I take the time to post because there are those who appreciate my input on making proper selections.

 

Nobody misleading anybody here as you are obviously misinformed to think so . When my own Evo had that turbo i decided to go to the external wg set up simply because i have a 2.4LR and i could spare a few hundred rpm of spool in favor of better boost control since i have more displacement, so again you're talking out of your *** without knowing any real information on why things were done the way they were, and you are absolutely right! this turbo is not as enjoyable as an FP turbo, and guess what, it doesn't cost the $3,000 an FP costs either, you wouldn't buy a civic and expect Lamborghini performance or do you? maybe you do, i wouldn't be surprised, and fyi my car is as fun as can be with my current 2.4LR 6466 set up putting down 858whp for which i spent a pretty penny, try next time to have real information and not misguided - misinformed personal opinions so you can make a statement based on facts, not fiction for a change. Also check the link so you can see some other people who had the "dumb idea" of putting an external wg on a stock frame turbo.

Definitely the whole thing, the TD06 wheel will allow you to make more power on the top end, while doing the compressor upgrade it's a good improvement over stock it will still be limited by the factory TD05 wheel.

 

This is the post that should have been said. This is the post that I appreciate, something that we can talk through about. Instead of just putting something down without some facts.

The FP Black is bigger than both 25g and 35r, it shouldn't be compared. I believe the Green is the better choice for this hp level. I haven't seen any 35r hit 700whp, can you show me? I've seen mostly 5-600whp with both 25g and 35r.With buying a turbo saving over a grand, I'd put an extra 150 and get the billet wheel. I totally agree with the internal wastegate problem. I'm having that too on mine. I'm not even using a 25g with a twin scroll turbine like you guys are. Mine is a regular t3 turbine for my SS.

 

You have sand in your clitty. if you cannt take negative criticism maybe you shouldnt post???

The size of a turbo refers to the flow rate of a compressor wheel. Theres hardly any recent results of original 35r because 95% are running 35r with a billet compressor wheel. but here are some ~ flow rates of the compressor wheels relevant. all 85 results

turbo = size= lbs/min = whp typical on e85
35r =61.4mm= 68lbs = 650whp
hta3582=59mm=72lbs = 700whp
black =hta3582= 59mm=72lbs = 670whp (held back due to turbine housing)
25G= 60.5mm= 60-67lbs * = 550?? (so far wooho!) *original or billet

does that help?

This 25g to me is simply a mismatched combo of wheels. The compressor wheel is capable of 650 whp but its being held waaay back mounted to 6SL2 turbine wheel. not only is it held back in power but spool suffers as well. the 25g turbo would be waaay better if it was mated to 6H size turbine wheel. It is an inexpensive turbo that can make over 500whp. If working within extreme budget constraints then it may a be a good choice for people.
