"Nice looking front bar on that car" Well Tayles, consider yourself at least partially responsible. Neil

Yes - Stroked 2ZZ-GE 1933cc. Neil

Hello all, A friend of mine who owns the site has asked to to pass this link around. http://www.ausringers.com/2008/04/04/osbor...urburgring.html I hope you enjoy the story. Neil

They are reliable. Bathurst 2008 marked 11 2ZZ powered cars in a row that have finished races of 12 or 24 hours prepared by NTE. It is not just production cars either. We run a Corolla Sportivo in the Nurburgring 24 Hour with a stroked 2zzge which produces 148kw at the hubs on a Dynapack Dyno and we have finished that last 2 events. BTW a stock standard 2zzge gets about 103kW at the hubs on our Dynapack. Neil

Blueprinted engines are still standard. Exhausts can be changed after the manifold. Engine management is free - we use Motec. Neil

Mr 22ZZ, I forgot to mention that I build engines for the Thrifty Celica #72 as well. And on Toyota related subject, I build engines and race engineer the #10 Lotus Exige that came 3rd in its class and 7th outright. Neil

For the third time in a row, Colin Osborne (2002 and 2005 Australian Production Car Champ) has won his class in an endurance race at Bathurst, beating the second placed Thrifty Car Rentals Celica by 3 laps, which beat the Conroy Honda Integra Type S by 1 lap. The Celica co driven by John Roecken and Neal Bates also finished 11th outright. Colin Osborne also won the Production class outright at the 2003 Bathurst 24 Hour and the Hot Hatch class in the 2007 Bathurst 12 Hour. Neil

If you have a choice, I definitely recommend the Mahle pistons. The Wiseco pistons give a lower compression ratio than standard, even though 12:1 is claimed. They also have relatively sharp corners on the valve cutouts, which is likely to be a gas flow restriction. I always check short motor static peak turning torque during assembly and the Mahle pistons show much lower friction than the Wisecos. Very importantly, the Mahle pistons give exactly the compression ratio the manufacturer claims. Neil

Just a little note. Be careful with the selection of a standalone ECU for the 2ZZ-GE. The Haltech, for example, can't handle the variable cam control. It can only switch from full retarded to full advanced cam timing not full control in between. Not many can. The Motec M400/600/800 can. Neil

Come on guys. 60K overproced for a TRD Aurion? You must be kidding. There are people out there paying more than that for Fords and Holdens. You can't tell me that an Aurion is worth less than a Falcon or Commodore. The technology and manufacturing techniques actually belongs to this millenium. Neil

Just a quick note to say that our Toyota Celicas have finished the 2007 Bathurst 12 Hour 1st and 3rd in class 11th and 13th outright. Neil

As the title says. I have a deal on tickets for you if interested. ph 0417 656 943 Neil

The 3zz ended up being a bit disappointing on saturday with peak power being 143kW. The encouraging thing was that the power at 5500 RPM went from 130 to 150kW with the Piper cams installed. Investigation of an occasional severe misfire that proved difficult to diagnose on Sunday turned out to be a faulty catalytic converter (Nurburgring 24 Hours rules require a cat). What had happened was that the cat internal matrix had melted and collapsed and had turned through 90 degrees almost completely blocking the exhaust. 143kW at the hubs is therefore not too bad with a blocked exhaust. I will have the car back on the Australian Defence Force Academy Dynapack Dyno later this month and will report my findings. Neil PS I checked my records and the power output of last years otherwise "standard" 3zz-ge was 140kW NOT 150kW as stated. I had 150kW in my head as that is what I was hoping to get on saturday.

I would definitely not install the Piper cams on a production engine. That would be highly illegal. I will be running the Piper Stage 2 cams in our Corolla Sportivo 1933cc engine on the dyno on saturday for the first time. I have driven the car on the road and I feel that the transition to "lift" is much softer and early indications are that there are good gains from 4000 to 5500 RPM. Of course time will tell. Watch this space. Neil

I am involved in engine building and tuning for 3 Celicas in the APCC, 1 Corolla that we race at Nurburgring in the 24 hour race, 2 Lotus Exiges and 1 rally Corolla Sportivo. These cars use the 2ZZ-GE. It is very important for performance to control the variable valve timing in closed loop. That is measuring the actual valve timing and tracking it using a Pulse Width Modulated output (PWM) using Proportional Integral and Derivative Gain (PID) control. Lower end aftermarket ECUs cannot handle this type of closed loop control and are at risk of delivering lower performance than standard. The only ECUs that I really know can do this is the Motec M400/600/800 series. Others may but I am very unlikely to use them anyway. We have 130kW at the hubs (Dynapack) DIN corrected for Temp Baro and Humidity on our "production" engines and 150kw ON OUR 1933cc strokers. Straight out of the box we get 110kW from Celicas before we play with them. Neil

This poor deluded fool is probably still hurting because a 2zz powered Celica (That is 1.8L vs 5.7L) won the 2005 Australian Production car Championship outright (Commodore SS not even in the top 5), and Celicas finished 1st and 2nd in the Production category of the 2003 bathurst 24 hour the 2nd car being 12 (yes 12) laps ahead of the V8 SS Commodore. A Celica also won the 2002 APCC outright. Neil

Zeerola, I'll try to get you a photo of the Corolla crossing the line at Nurburgring. That would be better. I did the engine for the Ferrier Corolla, so I don't mind at all. Neil

As I said the engine is largely standard (blueprinted) except for the stroker. On our dyno with DIN corrections, a standard 2zz-ge puts out about 145BHP. Neil

Other cars included Opel Astra 4 Renault Clio 3 Opel Manta 1 VW Golf 2 BMW 2 Audi A4 1 Audi TT 1 Honda Civic Type R 2 Ford Puma 1 Ford Focus 1 Ford Fiesta 1 Honda Integra Type R 1 Toyota MR2 1 Honda S2000 6 Alfa 156 1 Seat Ibiza 2 Stroking widened the rev range and moved it down. Neil

As many of you will know, we went to Nurburgring this year with the ex Leanne Ferrier (Tander) Toyota Corolla Sportivo. Our plan was to build a mildly modified production car to compete in the 1800 - 2000cc 24 hour special class (SP3). We hoped to complete the race in order to gather enough data to launch a more effective assault on the class in 2007. We thought that beyond finishing we might be able to finish in the top 50% of our class which is mostly occupied by super production and super tourer type cars. We also dreamed of a top 100 finish outright out of a likely 220 starters. We ended up 11th in our class and 77th outright after an absolutely trouble free run. We used 10 tyres, 1.0L of oil and 1 set of brake pads. The engine was literally going better at the end of the race than at the beginning, the clutch was perfect, the gearbox was as new. The engine is stroked to 1933cc and otherwise only blueprinted. We have 185BHP at the hubs on the Australian Defence Force's Dynapack hub dyno. We are very pleased with the result and will be better equipped for next years event. Cheers, Neil Trama

BTW my Corolla is now on its way back from Germany after our Nurburgring 24 hour adventure. It's not really my Corolla. It belongs to Toyota but they let us use it. Neil

The TRD diff does wear and its housing does break. Adjustments to pre-load are made 1 to 2 times a season. Neil

The plate/ramp LSD that we use was the only thing available when the cars were first developed in 2000. I would like to try a torque sensing LSD ala Quaife or Torsen but there are higher development priorities at the moment. Neil

As the heading says, Toyota Celicas have won the Australian Production Car Championship Outright. They have also finished 6th outright and 1st and 3rd in Class B. Team - Osborne Motorsport Car - Toyota Celica 7th Gen with 2ZZ-GE engine Driver - Colin Osborne Engineer - Neil Trama Suspension - Warwick Brooker Tech - Andre Lineker Logistics - Dave Jupp Footage of the final round and season wrap-up can be seen on SBS Speedweek on Sunday coming.

The dealer did this to one of my Audis once. They initially admitted responsibility, then denied it. I just put iin a claim to my insurance company attributing blame to the dealer, had the car repaired, and never heard a thing about excess etc. Neil
