Default Looking for turbo kit using the GT25 turbo

Soon I will be able to post in this forum with experience, but until I find the right kit, it will be curiosity.
I am really interested in the GT25 turbo, i feel it will compliment my driving preferences perfectly since Im not looking for extreme top-end. I was looking at a few kits and I would really like one which incorporates the GT25 turbo, and maybe even a top-mount IC.
If anyone knows of a company which sells a kit using this turbo (hopefully top mount aswell) could you please post a link? Thanks in advance everyone!

You got good taste. The GT25 is a overall great turbo

Redline Engineering is making me a stage 2 kit for 5psi, but with a specked out T3. The reason I went with this kit is because the kit incorporates the best of the best. Everything is stainless steel and tig welded. The piping to the intercooler is all aluminum. The kit comes pretuned around 6:1 fuel pressure, but it's different with each turbo. Theo is a great guy and he can build you anything for a great price. His kits are nothing but the best. There aren't a lot of his kits floating around, but EFOO has one. He got one of the first kits, and had minor problems with little pieces, but that is all fixed now with his new kits. Theo quoted me about $4200 with the GT25 turbo kit, including shipping. This will include everything for installation. He also throws in guages for a good price. I am getting an apexi EGT gauge for only 275 instead of 360. I am going off the subject, but give him a call. I am sure if you tell him Kevin reffered you, he might give you a little better deal, and maybe me too. And, unlike JCSports, you get the kit within a week and a half. His number is 1-904-788-7102

The next company I would look into is Forced Air Technologies. There kit goes for about the same price, but you don't get stainless plumbing. No aluminum pipe to intercooler.

Shiv's kit is probably the best, but he is only making a few for now, and if you are too anxious, then look elsewhere. Many people will be ahead of you on the list.

For the record, I am pretty sure any company offering kits can squeeze in a GT25 for an extra charge in their kit. And don't run over 5psi, unless you want to have to rip apart your engine. Yes, some people get by on 8psi, but why risk it until you have enough to go tech2 and internal work. My .02 cents

Not intending to take over the thread, but I have a few more questions regarding the gt-series turbos. How different are they are they from the reguar T3/T04S turbos. Are the GT's a a complete ground up redesign or simply upgrades of existing models with dual ball bearing center sections. Essentially do the GT series turbos, especiall the GT25 share common flanges with other turbochargers. This info would greatly help simplify building a custom kit around a GT-25 with regards to flanges and oil and water lines. It is much easier to buy parts off the shelf than to have to fabricate them

Sorry, but I don't think I can offer my resounding endorsement of Redline Engineering's "kit". The issues I had weren't minor at all.

If anything, Rallispec deserves most if not all the credit for making that collection of parts (which is what it really was, not a "kit") produce boost on my car. I'll have to see the new kits in person first before I'm willing to attach my name to one of them.

Isn't aluminum piping a bad thing? I thought aluminum had heat transfer characteristics that were unfavorable if you're trying to keep your intake charge cool.

I'm one of the few, if not the only running a GT-25 hybrid specificaly built for the EJ25. I am nothing but happy and would not trade this turbo for the world! I am fully spooled up around 2400rpm stright through redline. I think if it is correctly built you will be very happy. PM me if you have any Q's.

Robk, thanks for asking that question, a little bit of contrasting between turbos is good to know.
Thank you everyone for the replies, if there are anymore; keep 'em commin!
Thanks.

I have a custom GT25 for the EJ25 that you can buy in a turbo kit with top mount intercooler from Forced Air Technologies.

I really like the turbo, it spools very fast. I haven't noticed any sort of falloff by redline either.

It is much more responsive than the t3/4e that was on the car before.

Call Robert with Forced Air Tech and tell him Aaron referred you for the best pricing.

AaronB, thats the jackpot! Does this kit come with everything needed for the installation? My brother and I are going to do the install ourselves, so we just want to make sure we will have all nesessray pieces. Thank you very much for the reply, aswell as everyone else!
Dan coty
Ok, I just called them, and he reccomended the stage II using the T 04e turbo. It sounds good, but is there a diference between this kit and the minam kit? It does come with everythig needed, so far i am impressed with these guys.
I need opinions please, should I get the T 04e, or get the GT25 for 400$ more? Robert said the GT25 has 200rpm less spool up and otheriwse he cant tell the dofference between the two kits. Any input would be great!

My kit was the prototype for Robert's kits, so I can't answer any questions on installation, as it was built on the car.

He has sold quite a few kits now, and I have never seen any problems about the installation, so I would guess it includes everything.

I went with the GT25 since I switched to low compression pistons and had some pretty big plans for the car. The t4e was a very good sized turbo for our application as well. I was able to run a 13.9 with that turbo before the car was intercooled and tuned correctly.

Hope this helps,

Aaron

Yeah Efoo didnt have the same raving results as others, but I *think* I got my kit before efoo and i had nothing but good to say about the redline kits. Of course I had the luxury of being the prototype car. he redid my kit for me too. to stay on topic too theo said i can easily work a GT25 turbo into my car if i wanted to.

impRSa01 - when u get your kit in drop me a line and let me know what you think about it. I am thinking about swapping out my turbo too. I already have a Haltech ECU in and i am thinking my tranny is a bit more inportant right now, but still interested in more power across the band.

t.rod --> AaronB is running ~7psi, but has low comp pistons.... I believe the GT25 kit from FAT can run ~7psi with stock internals, but am not 100% on it

The GT25 is a turbo you put in your car when you have BIG plans for it. It is a very capable turbo for high horsepower from what I have been told by Forced Air Technologies, I would not likely use it to anywhere near its potential

So does this GT25 look like it would be a good match for an ej25 running 8-10psi with an IC and a TEC-II?
