This is what i want to know also. I just want to replace my turbo and turn the boost up to 12psi and call it a day on my daily driver. Do i need a rom tune or more fuel or can the factory ecu handle it?

Honestly, the setup doesn't really matter. Mainly the PSI. Stock T25's do not breathe past 220 at the wheels.. They pretty much stop making all power there.. the fact that is is making 270 at the wheels and not hitting a brick wall is more than enough for me..

h240 · 04-26-2012, 05:05 PM

So how is the turbo holding up?? Is there any other special mods that need to be done or is it a direct replacment..does a tune or injectors, maf need to be upgraded??

coupe92 · 05-29-2012, 08:57 PM

In for more info on this t25/t28 replacement as well. I have been running this turbo on my KA-T for around 8 months now, and about 4-5k miles. Spools fast, no smoking, pulls pretty hard. I have a boost leak or 2 (or 5) and a few exhaust leaks I'm sure, but this thing still spools pretty good and on my KA it's breaking loose the stock tires in 2nd when I hit peak torque. Have yet to dyno it though.. I have been running it from about 9-11 psi regularly with an adjustable actuator, however the stock actuator was set at like 14 psi and I couldnt lower it..This was partly because the turbo wouldn't fit my SSAC ka-t manifold so I had to clock it just a little, but this put the wastegate arm at somewhat of an angle, causing it to open a little later, but the fact remains that the spring is pretty stiff right away, I don't think you could get the wastegate they gave me to move under 10 psi.

I'm on the stock KA clutch at the moment and have developed some serious slippage, but I ordered a new comp clutch white bunny kit today. Once that arrives, I'll be trying turning up the boost to 13-14 psi. I still don't know much about this turbo though, and would like to get more specs on it.

^ how did you run the coolant lines to the turbo on your Kat?

I dont run coolant lines on my KA-t.. Just run a turbo timer. coolant lines are only for cooling after the engine shuts off..

But people do run coolant lines. Some run them from the throttle body pre-heat linews.

Yea I have seen that the only good write up I've seen, but I've seen people use the Goodyear heater hose and I feel like that would melt, and the cost to make custom an lines from the tb to the turbo will prolly cost more than the turbo. But I bought the Isis 3871 cause I thought it was just oil cooled, but like you said I may just run it w/o coolant lines hooked up

swayc09 · 10-05-2012, 06:08 AM

i heard you have to run the isis trubo lines with it?

NightRider2.0 · 10-11-2012, 08:27 AM

Couple questions. I just purchased DIF Forged Oil/Coolant lines and I wanted to know if they would fit this turbo and also, would I need to run a restrictor with this turbo?

As long as their oil feed line is a 3an and NOT a 4an. Then yes you should be able to use their turbo lines. No, you do not want to run a restrictor on this turbo.

thanks

Is the downpipe flange on this turbo different from a Garrett? I've heard some churbo's have a slightly different flange. Thanks

No, it is identical to a Garrett 5 bolt flange/S14/S15 outlet flange

thanks

I am buying the Isis T25/T28 and i need to know if the oil inlet line correct location is in the item in the picture and if the coolant lines has the inlet and outlet and Many Thanks Anticipated.

Maichael · 05-17-2013, 04:20 PM

Thanks for the great info!!!!!!!

nissanfreak317 · 06-22-2013, 01:50 PM

Will this bolt up to my ca18det? Also, which turbo lines would I need to get to go along with it?

Nissanfreak317, we attempted to test fit this turbo on a ca18det and it would not bolt up, Sorry.

nissanfreak317 · 07-01-2013, 11:01 AM

Well, thanks for taking the time to do that. What didn't line up? I thought that any sr20 turbo would bolt up to the ca. Good thing I asked, haha.

Sorry, we should have been more descriptive, our apologies. The o2 extension didn't mount up as the t25/t28 uses a t28 back housing. You cannot simply use an sr20det elbow as the 3 bolt flange is clocked differently. You can, however, use your ca18det elbow and drill out one of the bolt holes to fit accordingly. As for the turbo lines, they will have to be custom made. We can make these here for you if you are interested. Just one more thing also, the turbo must be clocked in order to fit properly.

The price listed on this post is outdated. This thread was started back in 2011 and since then, the price for these turbos has risen. Currently, ISIS replacement turbos are selling for $359.99, marked down from $400.00.

ISIS performance has recently made remarkable improvements on the quality of their turbos. Every single turbo is pulled apart, inspected, re-balanced (if needed) and serial numbered. Also, all ISIS turbos are now using dual overlapping bearing seals. All in all, the new improvements has made one of our best selling turbos even better and we are excited to sell them here.
