Hey all.

At the moment, Im starting my 2.3L rebuild. Ive currently got a 20G that im running on the stock bottom end, but I have been looking at a Trust/Greddy T67 Turbo kit.

I have seen the Trust/Greddy T67 make 410hp on a 2.2L Tomei motor w/ Cosworth CNC head, Hypertune Manifold, BC 280's. It makes full boost (25psi) @ 4,100 RPM and makes max power at 7,300rpm.

Has anyone had any experience with this turbo on a 2.3L? How did you find it? I want to have full boost in by 4,000rpm and max power around the 7,000~7,500rpm region. The goal is about 400~420hp, which is quick off boost and has a BRUTAL midrange with little noticable lag. As the car will be used in Time Attacks, Circuit Battles, Touge Runs as well as to be driven on the street during the weekends, Im really after a setup that doesn't push the limits of the internals, but rather has a 'buffer zone'. Im really after a strong, reliable setup that will last. My engine build will consist of the following;

• OEM 4G64 100mm Crank
• Carrillo Pro-H Beam Rods w/ CARR Bolts
• CP 'Stroker' Pistons (9.0:1 CR)
• ACL Bearings
• ARP Main & Head Studs
• ATi Harmonic Balancer
• Kiggly Springs, Ti Retainers, Steel Seats
• Supertech 1mm Nitrided Oversize Valves (Intake & Exhaust)
• Supertech Valve Guide (Intake & Exhaust)
• Ferrea Locks
• Tomei Sump Baffles
• FIC 1050cc Injectors
• Haltech ECU

The car already has the following modifications and is making 270~290hp on a sick motor (loosing compression);

• Trust M-Spec Intercooler
• Custom Turbo Back 3" Exhaust System
• MIL.SPEC 100cell Cat
• Kelford 272* Cams
• Fidanza Cam Gears
• Walbro Intank Fuel Pump
• 20G Turbo

I will hopfully be adding a T67 turbo to the mix. What do you guys think of my setup? I dont have enough money for a turbo kit during the build, so its either this T67 turbo kit, or wait another 12months and just run the 20G for now, which wont be good for max power, but it will be VERY responsive.

I have also considered puting ceramic coatings on the pistons, what is everyones thoughts of this?

Also, should I run with the CARR bolts or the WMC Bolts for the rods? Is it worth the extra $300 odd for the upgraded rod bolts?

Regards,
Alex

 

I had the Greddy t67 turbo kit with my old Eagle 2.3 stroker kit. I made full boost 23psi at about 4200 rpm and made 435 hp and 410 lb ft on 91 pump gas and 490 hp and 420 lb ft with 110 octane on the same boost at 5000 ft elevation. I have personally seen this kit make 576 hp with i believe q16 an a stock block 06 MR at this altitude. If you wanna buy the kit new forget about it. There are so many more turbos BETTER for the price. I bought mine used for 1200 bucks so i said why not.

 

No no, Im going to buy a used kit, that is going for a good price. I owuld never buy this kit new!

Ill be running on 98RON fuel, which I beleve is the same as your 93Octane.

So using that, I should get spool closer to 4,000rpm.. I NEED full boost by then, otherwise I dont think I will go this kit.

Thanks for your personal experience mate!

 

Get the Fp red, blows the greddy outta the water and spools faster.

fp red man ...

 

^ FP RED is stupid expensive, and we have not seen the gains over here in Oz. The only people making over 400hp on a red are running E85.

Im not even considering a Red, Green, Gold, Blue or anyother 'bolt on' style turbo..

Although the T67 might look overly large and laggy compaired to the RED, im fairly sure it wouldn't create as much heat in the intake charge as the red because of the big lazy compressor housing. I need to try and keep this thing cool as well, as we will be tracking it. I cant afford to push EVERYTHING to the limit. I need some buffer zone!

Its either the T67, or my 20G turbo. If I miss the T67, 20G it is untill I can save for a GT3082R Twin scroll, which will take at least 12 months or more.

 

I'm not sure how you don't see more than 400 on FP reds on pump alone around there.

I was going to say look into the 30r's but you just said that. Everything you're describing that you want says FP Red. 410hp is low for a t67, a red should make at least that power and spool way better. They are too expensive though.

Just find a good deal on a 35R or 30R.

 

I hate how everyone says get a red, get a red, get a red.

Reds are prone to failure on open track, far less often for drag or street use.

 

Maybe our dynos just read lower or something. We have a few cars here on Greens and Gold turbos.

Car#1: Cosworth M2's, Evo Green, 25psi, E85 - 372hp
Car#2: Kelford 272's, AVO Gold, 26psi, E85 - 409hp
Car#3: Cosworth M2's, Evo Red, 25psi, Built 2.0L Motor, 26psi, E85 - 395hp
Car#4 (Track Car): BC 280's, T67, 25psi, Built 2.2L, Costworth head, 25psi, 98RON - 410hp
Car#5 (Track Car): Custom 2.4L (block, cams, CNC head etc), GT35R, E85 - 585hp

No serious track car here uses any type of bolt on turbo. They are all HKS, Trust or Garrett kits. The bolt ons just dont cut it.

 

Anyone else want to comment on the setup as a whole?

Ted B? Scorpion T? John Bradley?

 

I also hate how everyone jsut says "Get a red.. [/thread]"

 

^^ lol At "get a Red" it's not the be all, end all of turbos. If your getting a good deal on a t67 then pic that up.....or wait a bit and get your GT30, honestly its all up to you, get your GT30 faster and deal with your 20g, or wait a bit longer and enjoy the T67.

I personally would go with a GT35 :-) but i love bigger turbo's

 

I personally would say to run your 20g ***** to the wall, on E85 if is readily available in your area. You have the injector for it with the 1050's. Save your money for now, and get to know how to push your car to its absolute limit. Next year, when you are ready to go to the twinscroll setup you want, I'd say do FP's 3582hta turbo, with a divided t4 backside in a 1.06 a/r. That will give you all the headroom you could ever want, unreal transient response and spool, and have the ability to break 500whp on your 98 RON fuel. The 30r family of turbos will not make much more peak power than a Red, so I would suggest staying away from that route. Feel free to pm me if you have any questions about twinscroll setups.

 

I'm making 430whp with my 2.3 stroker on 98RON with a HKS gt3037s full boost and torque at about 4100rpm aparently gt35 is 500rpm later.

 

iv got the t67 on a stock bottom end evo 8 and i spool right around 4k. with a 2.3 you will have really good spool. the turbo is good just make sure you have a large oil feed line. my first one blew due to lack of oil. my new one is good though. compressor side is real big but hotside is on the small side which gives u the decent spool. yes the turbo is old school but it works so use it!
