ATP EVO Big Turbo Kit
Some info -
GT30R, GT3037S, GT35/40R and GT3071R, which one will it be? Is it just a matter of HP? Do I want 400HP? 500HP? or 600HP? Want answers? We can help!
We'll break it down for you so you know what to expect! By plotting out some actual data (that we've collected) on how each turbo responds specifically on the EVO8 engine combination, you can draw you own conclusion!
Some background on the above turbochargers:
The GT30R, GT3037S, GT35/40R and GT3071R are exceptional dual ball bearing turbochargers built by Garrett to cover a wide range of engine sizes and power ranges.
GT30R - A very popular name for a SERIES of Garrett ball bearing turbos, ranging from 350 HP all the way to 650 HP. Commonly mislabled as ONE particular turbo, but in fact there many wheel combinations built by Garrett referred to as "GT30R's". Many turbo selection errors have been made in the industry as a result of the wideness of the HP range in the GT30R family, ie. larger wheel combinations used in smaller engine (lower HP applications) resulting in poor spoolup. GT30Rs' are part of Garrett's earlier ball bearing line-up (consisting of about a dozen different wheel combinations) and are still very popular and reliable turbochargers, but because of its history of "misuse" and improper application matching and its lack of single identity, can no longer be used as the "benchmark" for comparison.
GT3037S - A particular variant of the GT30R family, but more commonly, another one of Garrett's ball bearing turbos found in a certain Japanese tuning company's turbo kit, popular for producing up to 500 HP. Commonly referred to as "the GT30R."
GT35/40R - aka the GT35R. On the larger end of the small frame ball bearing family. Quickly becoming the favorite for 600 HP high revving 4 cylinder engines. The GT35/40R goes where older and bigger turbos such as T61's and T64's (bigger, bulkier, slower spooling) would have gone, except the GT35/40R's quick spooling characteristics make these 600HP setups more streetable.
GT3071R - A brand new ball bearing turbocharger recently created by Garrett engineers to help fill the gap between smaller 300 HP turbos and the laggy GT3037S. The GT3071R is also one of the Garrett engineers' favorites because of its superior wheel match (between the compressor and the turbine wheel). A better wheel match means higher levels of efficiency. Higher levels of efficiency mean the turbo works less and achieves more and is happier and makes more power reliably. This is quickly becoming one of OUR favorites as well. Our findings:
The GT3037S - This "benchmark" turbo, used by the popular Japanese kitmaker, was the first to find its way into our prototype kit. We were very impressed with the power, but was not impressed with the way the "500 HP" turbo spooled up on the EVO8 engine. We quickly pulled up dyno charts of the same turbo installed on the EVO8 engine via other popular kits utilizing tubular manifolds and found that those setups spooled up yet another 300-400 rpm later. We deemed this combination unacceptable for the average EVO driver.
Since the GT3037S represents one of the newer and more preferable variants of the GT30R family, we decided to skip the rest of the line entirely for EVO8 testing.
Then came along...
The GT3071R - A brand new "450 HP" ball bearing turbo introduced by the Garrett engineers partly to solve our EVO8 dilemna. Wham! It was right at home! The unit complimented the EVO8 engine well and performed to expectations. Boost was seen 700 - 1000 rpm earlier than the GT3037S and only 200-300 later than stock. With some tuning and larger injectors, we managed 375 WHP on modest boost: achieving our goal of a setup that makes 450 crank HP, spools close to stock and does not require swapping out everything under the sun, ie. FMIC, cams, headwork, etc. To get the power, all you you need is a nice free-flowing 3" exhaust as we have installed on our test car.
GT35/40R = 600HP? Definitely doable. We initially ran the kit using Garrett's turbine housing, but found the A/R to be too aggressive for street use on the EVO8 2.0L. We've massaged our own turbine housing to scale down the A/R and have managed to get the GT35/40R to spool up as quick as the GT3037S spools on other off the shelf kits. 400+ WHP was quickly seen on low boost and 660cc injectors on an otherwise stock engine. Our Stage III turbo kit for the EVO8 (aka "Stealth kit")
After months of testing and development with the EVO8 engine combination, we have devised an upgrade system that is both elegant and simplistic while accepting no compromises in power potential or reliability. With POWER and RELIABILITY being the two key criteria for the development of the EVO8 turbo upgrade kit, we set out to test every possible hardware combination available. In our kit, you will find a system that integrates a plethora of unique but well designed components that compliment each other to achieve those two things that you care about most. In addition, in an attempt to exceed the customers' expections we have added other features such as a "direct-bolt-up" housing that overcomes the "reverse-rotation" issue, v-band downpipe discharge, bolt-up oil/coolant kits, etc. in order to make the installation process as simple as possible. All this while retaining the appearance of a completely stock engine bay.
The kit hardware will consist of the following: Garrett Prototype GT Ball Bearing turbo w/ATP Proprietary Housing with GT inspired High-Flowing Valute Bolt-in design retains stock manifold - Retains stock heatshield for OEM appearance Steel braided lines and fittings for oil/coolant connections Tial 38mm External Wastegate Stainless wastegate discharge tube with downpipe re-route Silicone connectors and clamps All mounting hardware, gaskets and CNC machined fittings 450 crank HP utilizing the ultra efficient GT3071R 3.0" Stainless steel downpipe w/stainless O2 housing 100% bolt-on design. No welding, cutting, or fabrication
GT3071R w/.63 A/R kit price: $2399 Note (as of 06/21/04): By popular request from our customers, the intercooler discharge pipes and silicone couplers are now included in the EVO8 kit to insure a true bolt on system.
Other turbo options available for customers that insist:
GT3037S w/ .63 A/R - No additional cost - GT3037S spool up dyno chart
GT3037S w/ .82 A/R - No additional cost
GT35/40R w/ .63 A/R - $350 extra - GT35/40 spool up dyno chart
GT35/40R w/ .82 A/R - $350 extra
PLEASE INDICATE TRIM LEVEL UPON ORDERING. The base level kit is the GT3071R W/.63 A/R for $2300.00 shipped! We are more than happy to answer any more questions you may have to aid your ordering process!

I am trying to decipher all the turbo talk. Which turbo would be the best for road course. I do a lot of track days and want good power, but no crazy lag. Thanks for any help.

Watchout is right. The GT3071R is a great all around turbo including road course/track day events. Quick spool and decently wide powerband helps provide strong tourque to get out of the corners in a hurry.

Wish I had an extra 2500.

Yep, we'll probably keep this going through the end of the month since we have had a lot of interest.
Just give us a call when you are ready!
