^^^^^ They are cheap re-grinded cams: 256/8.9 . I got done 3 years ago at wade which costed me $120 in total for 2x. I guess they didn't even know what a CA18 is back then. You can use Tomei Pon cams which will give better result. ATR28 G3 will be available next year as in a direct bolt on form we are doing our modeling at moment. This CHAR is highflowable into Stock R3x Turbine housing. by calculation it should give similar result with lot faster response. We will make one for evaluation and should have the results by new year. But drop in an email if you are interested in evaluation.

220rwkws is very easy. The high flowed turbo should perform between 230~250rwkws. It should be archived around 18psi or less. By calculation it should archive peek out put of 450HP at 1.3Bar. There are many dependencies, calculation is normally calculated based on 75~80% of flow capacity. and there are many things that we can do to increase the HP with the ATR28 CHAR in a restrictive environment, but it will results more lag. The most common profile that we use for R33 high flow is ATR28G2 (400HP) and older G3(450HP) profile. The Current G3 (on the 282rwkws CA) requires a big turbine wheel which the stock housing doesn't seems to have enough meat to be machined out.

Thats great if you can get some results from its max potential. The estimate by calculation is roughly 250rwkws. It will normally take 3~4 days to get the turbo ready.

Sorry we don't. But we can make them brand new and mail it over if you need. Had many US and Eurp customers lately as our dollar is sitting very low.

GTR turbos are easy we can put in ATR28SS 350HP CHAR for twin setup. Those are very very tuff little turbo made to handel high boost. Should get you 400rwkws with excellent turbo response.

yes, we tab in factory thread so stock lines do bolt on

First of all we have to use bigger wheels to flow more air. We use aluminium compressor wheels and Inconel steel turbine wheels. All parts in the turbo are specially designed for high boost, and we warranty that for performance applications. So yes they are lot stronger then the stock turbo.

Is that the HyperTune in Spring valve? Owner's name's Yin?

Yes it will still cost $800 to high flow as its basically using factory housings on a new Turbo core. So you might want to send in a cheap blown one to do the high flow. The ATR turbochargers has no issues to handle 25psi. But factory turbine housing can only hold 20psi.

At this stage we perfer to use Sleeve bearings turbo system. Ball bearing is optional at additional cost. ATR43 sample turbos should be ready towards end of Jan comming year for members who are interested to evaluate along with my self.

Thanks for support every one. Since start of 07 we've taking lot of advice from different turbo builders, absorbing different theories and put all creative thinking into new ATR turbocharger manufacturing. We do thanks to Trent, Sam, Nick and all other tuners and forum members who participated in tuning and testing of the new product. The ATR28 450HP profile we made 255rwkws on a CA18det, RB25 should be making towards 270rwkw with excellent turbo response. We are working a the ATR43 at this stage. Building Aluminium models for sand casting at this stage. This will be a "small looking" direct Bolt on turbo for R33 to produce around 280rwkws.

It all depends on what you do as calling it “high flow”. What we do is: Re-profile both factory compressor and turbine housings. Assemble profiled housings onto ATR28 450HP profile core assemble. So basically its a brand new turbo with your factory housings for direct bolton purpose. All ATR turbochargers are covered with 12 month warranty for performance usage.

Its a G3 TR43. profiled to support 300rwkws. the oil feed line will only work with this turbo.

7Psi springs are not designed to hold that much manifold pressure. So its only made to work with stockish applications. If you need more boost run stronger actuator so it can hold more pressure. external gates are still highly recommended for high performance applications.

Well that is why we made a 14psi actuator for high boost settings. Put that in and you can boost to what ever 14psi+ you like.

Need to exchange for a 14psi actuator if you need to run 16psi. We gave you a 7PSI actuator consider you didn't have much modifications to support 14psi back then. PM me.

it sound like in HP. can you put up the dyno sheet? TR43 standard make 230rwkws (331HP) at 14psi with stock injectors and AFM after a good tune. You should get 215rwkws just by using 98 fuel and slight timing advance. Check to make sure your cat is not restricting flow, and Please Make sure the internal wastegate is shut probably. Lot of people doesn't adjust the wastegate rod after rotating the housing on it. below is off a rb25det all stock fuel and afm running a dr.drift remaped ecu.

All Reasonable offers accepted.

This is a 1993 model GTST manual turbo R33. We bought this car few month back for TR43x internal wastegate development and evaluation. Key Features of this car: 150,000KM 170PSI all cyc. 600x300x75mm Front mount intercooler kit TR43 internally gated turbo running 7psi. Custom made 3inch front pipe. keenwood CD/Tape player with speakers. Cruise control A/C, Electric mirror and usual stuff This car drives perfectly and smoothly. How ever it does require a respray, as the clear has started to pill on the front bonnet and guard areas. This car has been complainced and had Act Rego that run out on mid June 08. It can be registered any where in Australia. The asking price is $9500 as it is, Serious Buyers are welcome to see and test drive the car. I will not accept any trade ins at this stage. Call 0413457185 for more information. more photos at: http://www.digi-hardware.com/r33090608/

You need to move the AFM away from the turbo's mouth of as far as possible from it. Its best to put in to Intercooler piping and do a tune after.

Lot of turbos might looks similar but performance wise they can be very different. Like TR43 and TR43HF they looks exactly the same but performs very differently. Their trim and porting in the housing and the sizes of turbine and comp wheels makes quite big difference. The power band wise, If you make a turbo with a tiny comp wheel then its going to spool up mega fast but power band dies off around 4000RPM. just like diesle turbo. Most street performance patrol turbos are focusing on good mid range, Normally from 3500RPM to 7000 RPM depends on engine sizes, the bigger the better. TR43's power shot dyno read out

Simon: First of all I don't remember that we sold you a TR43 high flowed version or if you were one of our customer at all. We are not KKR so If you had bad experiences from other turbo suppliers please chase up with them instead. The TR43 Hi flowed turbo developed is a High boost High Efficiency project built with 360 degrees trust bearing and a lot stronger shaft. Supra_R32 on this forum has made 245RWKWs at 18PSI full boost at 4300 RPM with a RB20 we have made 280RWKWs with this turbo on a 1.8L CA18det !!! . Even for a Standard TR43 we've made 190RWKWs on a RB20det with 10PSI of boost with factory every thing. Turbo is just a compressor, If you've bought this turbo and not making power, then I suggest you to check your tunning as well as other supporting mods.

Too much boost and hitting Boost cut? have the AFM maxed out? or maybe faulty AFM? are you running ext WG?

2007 Drift Fest. HyperGear TR43 powered CA18det S13.5 in car footage. The car's running 220KWs wheels on 15PSI with 695Nm of torque. (This power is not much compare to RB25 and RB26s, But it is not bad for a CA18det). Part 1: Part2: Out car footage. (Its the Red S15 / S13 with black bonnet. I also included some nice sliding actions from other drivers) Part 1: Part2:
