  1. What happened to, "these emo's are really easy to drive, but i'd never compete in one"? Did you ask lowana Garwood about buying her emo? it's YT's old one, even comes with a 2.2
  2. Now the car has been in a big event, I thought I better post some findings about the car. 1) You need a decent sump! From the datalogs, the oil pressure will constantly drop into the 0-5psi range under heavy braking (cornering and acceleration forces don't bother it). It only does it for less than a second at a time, but as we found out, you're driving a time bomb. 2) Spending money on good shocks was worth every cent. We probably only tuned the car 70%-80% of what it could be, but the way the shocks handeled the big bumps really surprised me. Coming from the Bilsteins in the GT-R (which I was happy with), it was in another leage. 3) airbox and radiator worked like a dream. Intake temps were only 10-15deg above ambient. And the coolent never got above 85deg on a stage, you could see the thermostat opening and closing from the datalogs. As the temp woudl go from 85 down to 78, then back up to 85 2-3 times over a 30km stage. 4) Fancy dash was worth the money. The data from the logs was invaluable during the event, and I found the dash clear and easy to read during the stages. If you're racing you will spend just as much money on gauges as a dash. 5) ITB have plusses and minuses. They have given the same effect as bigger cams, with a loss of power down low, but it does keep the power going right to 8000rpm (and beyond if you had the turbo for it). I personly hate the throttle responce from the std 20, I think it makes gear changes slower (waiting for the engine to rev down so the box will engage the next gear), and it makes the engine feel like it's attached directly to your foot. I'm going to try some cam gears, and hopfully that will give me some responce back..... but if I didn't need to drop the rev's back to 7000rpm from 8000rpm, I don't think it would have been as much of an issue. I don't think I'd recomend it for other people, but I personly think they improved the entire package. 6) catch can design needs more thought than just hooking a single tank up. Constant high rpm needs oil restrictors, oil air separator, thicker oil, and a return to the sump.
  3. We are already working out how to make the car better, and how to keep the oil in the engine.
  4. I know Haltech are adding support for an Ethenol sensor (same as the new e85 commo uses), so your tune can change the match the ethenol %. I'm sure other ECU makers are doing the same too. In reality the blend is never going to be 85% all the time, so these sensors will probably be the way forward for us. But I live in tassie, so I can only buy E85 in 200l drums for the forseeable future
  5. it would be roughly the same as a cfd model of a house
  6. his advice will be to put a 20 back in it
  7. When was the last time BP was avaliable in Queenstown during Targa? in 08 we got greeted by a closed sign, and we never took the risk again.
  8. If your only looking after 1 car, you can almost meet your car at the end of every stage. We often saw Brisby watching porn on the side of the road
  9. pics of said sparks? Gotta thank the Penske's for that, they handle big bumps like that with no problems
  10. if only there was some compeditor involved, with a big hiring company that could supply shitters....
  11. How much to post the cam covers to tassie (7250)?
  12. I only just looked at warrens times, far out him times were impressive once he got the car going again.
  13. Was at Baskerville raceway. I've now been over the datalogs, and the oil pressure keeps dropping to 0psi under brakes (didn't for targa though) The lag wouldn't have been a problem if I was able to rev to 8000rpm, but the new engine had issues to prevent that, so I lost 1000rpm off the powerband.
  14. it doesn't help when the officals don't understand the last time issue. Gunns Plains were the only people that caused issues, there was a few of a bitching about it at the start of Riana.
  15. did you have problems with it breathing at 23psi? I've 2 rb20's in a row not like the boost.
  16. Dunorlan: Rinideena (wet):
  17. Well after Targa I think it's time to get a gated sump after i ran a bearing the night before the event. I'm also going to rethink the breather setup to stop it blowing oil out of the breathers all the time, and last of all put some cam gears on to improve response. I gained some motivation today, put the dead engine on the engine stand, and drained the oil out. There more than an acceptible amount of bearing on my magnetec sump plug. But I ran out of motivation when it got time to remove the sump. Some incar from targa Riana: Cethana:
  18. pics? what weight are the springs?
  19. We don't need the shit we talk in the car to be made public.... although it might have made the party tape funny I got the audio cable with the camera, but the PMD has a beefy 3 or 4 pin connector on the back, and we cbf finding the plug... even though jaycar probably sell it for like $1.
  20. PMD enduro http://www.pmdraceproducts.com/incarcommunications.html Very happy with it, heaps better build quality than a terraphone
  21. So did mine. Look for the "advanced loader" when you upload.
  22. Warning long post, I wrote up a report from our Targa adventure. Day 0 -2 We decided to head down to Baskerville raceway to learn how to setup the new suspension, and to bed in the new pads. We did about 50 laps, and learnt a lot about the suspension. But we had blown a lot of oil out of the catch can. Feeling pretty happy with our self’s, we put that car on the trailer and went back to Launceston. Started the car up to get it off the trailer…. Knock knock knock, then ran fine, it had oil pressure so I thought the oil might have run/shaken out of the pump during the trip. We changed the oil and it didn’t’ make the noise again on start up, and worked on the car till about 1 am Day 0 -1 Finished some tidying up before scrutineering (not that it matters with AASA), but the headlights stopped working 30 mins we were due to headup (the only thing that they check). Damo was running some peak, and dodgied it so we’d pass. I jumped in the car and headed up to the silverdome. After about 2km I started to hear a quiet tap tap tap at 3000rpm…hmmmm. 2 more km later the tap tap tap, was a knock knock knock. I got on the phone to Damo to start looking for an engine. Did scrutineering and paperwork, then looked at our engine options. Damo’s won pretty easy, as it was free, and it’d done 2 Targa’s already (used it for recce). Damo and I rounded up some mates, and took the car to the workshop and spent got 3 hours in on the engine removal before we had to go to drivers briefing. Rocked up back at the workshop at 6, and set to work on the 2 cars removing engines, 2 people per car. It didn’t take too long to get my engine out. But then we had to strip the plenum, water pump, and timing belt off my engine. By 10:00 we had Damo’s engine out, and started the ancillary transplants. I had been lent a super baffled sump off an RB25, we waisted an hour in cleaning it up and trying to fit it…. Unfortunately the oil pickup wouldn’t work on the RB20. So the old sump had to be cleaned out and refitted. By this time it was 1:00 am, and Crump, Steve, and Travis had pulled to plug so they could get up for work/navigate in Targa in the morning. Damo and I were the only ones left to put the engine and box back in the car. As the night went on, tempers started to wear thin, as we couldn’t find tools, and the floor was covered in a thin layer of coolent and oil (very slippery). By 3 we had the engine and box bolted in, and set to work on the radiator/loom..etc. At about 3:45 I start putting the coolent in, and found one of the copper washers on the turbo had been damaged. After a heated discussion on what we should do, I just pulled the bolt out, slipped another old washer on, and crossed my fingers (while having coolant rain all over me). 4:00 am rolled around, and we fired the engine up… it went first go (even on E85). Surprisingly there were no leaks, and we spent the next 30 mins bleeding the coolant system, and checking the car over. I finally got home at 5:00am after dropping Damo home. Day 0 I had organised to get the car on the Dyno at 7:30 in the morning, as the tuner said “putting a new engine in is like a new girlfriend….they are never the same”. So I got up at 6:30 (1.5 hours sleep), I felt really sick, dry reached a few times, jumped in the car and went to pick the Skyline up. It still started, and even drove up the road. Brad the tuner was is a very chirpy mood, and was winding Damo up pretty bad, Damo was about to knock his teeth out. Got the car on the dyno, and it dropped 40kw straight off the bat, did another pull and it dropped 50kw. Brad said the engine would make the event, but would lose power the hotter it got. Apparently the head was pretty tired. We got the car checked in at the silverdome at 8:30 (30mins before the cut off), and headed down to the prologue. We didn’t recce the prologue, as every other year the field had been run through the stage….not this year. We parked the car in the park, and got to meet some people from SAU and jaw off for a few hours before we headed out. We were too tired to be nervous at the start line, we took off, and it became apparent at the first corner that the untested 235 tires were going rub on the skirts every time I hit the brakes, or turned the car. I ignored it, and ripped a few skids. We were slow, but didn’t really care at the time. Waisted a few more hours in g’town, then headed back to Launceston to fix the skirts. At service we found that oil was still being blown out of the catch can. I tipped more oil in the engine, and dropped it in the silverdome and went to bed. Day 1 We had an early start as we were slow which was good (we were thinking of going slow anyway) as we didn’t have any gravel to dodge on the road, cause we were in front of all the EVO’s and STI’s. The morning was pretty uneventful apart from having to use the hand brake to dodge a crashed car that hadn’t put any triangles out. After the first few stages I checked the catch can, only to be greeted by a big mess of oil through the engine bay (again!). So I tipped more oil in the engine, and dropped the revs from 8000 to 7000. At lunch we wound some more rebound into the rear shocks to stop the rear from bouncing off the bumps. Sheffield was straight after lunch, and we had a crack. Got 8th fasted EM, passed a car, and was nose tail with the next car as we went across the finish line. The stage didn’t record on the camera for some reason  . After the last stage we got a one way valve, and got the catch can and turbo oil drain modded so it’d drain back into the sump. We installed the new oil drain setup at the Targa expo, which created some interest with the public. Day 2 Started the car up to test the oil drain, and it didn’t leak. But we got 5km from the silverdome, and noticed a lot of smoke. Damo’s house it on the way to the Sidling, so we pulled in there (running heaps of peak), and found the oil drain gasket hadn’t sealed. We had 30 mins of late time to fix the problem. Somehow we got the drain off the bottom turbo, gasket goo’d it, and got to the Sidling within 1 min of our late time, but we were last car on the road. The stage was like a gravel road, I had ¾ of the car off the road at times to stay in the racing line. We made it to lunch with no other issues, apart from the catch can still filling up, but it wasn’t all over the engine bay, and seemed to be draining back into the sump. We finished the day with no other issues, and got an early night (hooray) Day 3 Day 3 is a nice short day with more flowing roads. On Dunorlan I hit a railway crossing flat, and Damo’s guts almost fell out of his arse, but the car didn’t even know about it. Next stage was Stoodly, and ½ way through the stage one of the nuts came off the bonnet pin just after I clicked 5th, which left ½ the bonnet flapping in the air It was a short stage, so we kept going at race pace. We fixed the bonnet at the re-fuel after the stage. Rest of the stages were enjoyable and uneventful. At the end of the day I drained 3l of oil out of the catch can, and decided to pull 4psi boost out of the car to stop if breathing. Day 4 This is the longest and best day of the event. Cethana is my favourite stage of the event, we had a good crack but still didn’t have a good time (1:00 slower than I used to do in the GT-R). Gunns Plains had been shortened, and we got a good time on it. Riana was our most memorable stage of the event. We had marked the first series of crests along a 900m straight as completely flat, but after we got massive hang time, and almost landed in the gravel we didn’t think it was a good idea. It took Damo almost 1km to stop giggling like a girl. Unfortunately there weren’t any photographers at that crest. The next series of crests I backed off a little for, but still got a good photo of some air out of it. Getting towards the end of the stage Damo missed a call on the now infamous Snowman/Newton corner . I tipped the car in and hoped for the best, and luckily we came out the other side just fine. Hellyer gorge was dry until we stopped at the finish line, and the heavens opened up. Driving along the highway we worked out how to sort of clear the windscreen. But the next 3 stages were wet, and between the screen fogging up, and the wipers being next to useless at speed, we lost a lot of time. But faired better that a lot of cars on rosberry (one of which burnet to the ground). On a good note, the car hadn’t breathed a drop of oil all day Day 5 The first stage of the day was mainly wet but no rain. I softened the shocks off in the morning (should have done it for the wet stages the day before), and the car felt pretty good on the wet roads. Mt Arrowsmith is 59km long, and was 80% dry, so I stiffened the car back up again. We passed a GT-R on the stage that was only 10-15 secs behind us on the leader board, but also got passed by Steve and Kel. The stage was wet at the end, and we once again struggled with not being able to see. The rest of the day is a lot more relaxed after Mt Arrowsmith. They were a mixture of wet and dry, so I softened the car back up again and left it. We made it to through to the finish in one piece. We got 13th in early modern and 1st in our class (7MSB). Damo did a great job, especially since it was his first pace noted rally, and the only time we had heated words was after about 3am on Tuesday morning. Now to start planning for next year to get up the order, and stop rust proofing my car.
  23. don't do it unless you want to find your car parked at the bottom of every hill that you park it on. GT-R rear hubs are 1/2 the weight of Gtst ones, so you will get a total of 5kg savings with the alloy ones. And the hydro will weigh more when you add the weight of the lines, master cylinder, and handle..etc
  24. oh it's been a loooong 48 hours. I ran a big end bearing on the way to scrutenering. Damo offered the engine out of his 4 door (it's already done 2 Targa's through recce). We rounded up some mates and went to work, had to strip the throttle setup, water pump and timing belt off my engine, and put it on Damo's. By 1:00 the new engine was together, and Damo and I were the last standing. We installed the engine and box, and by 4:30 the engine was running. I got home at 5:00, got 1.5 hours sleep, and then got the car to the dyno for the check up.... lost some power, but the engine is safe. bad luck done with!
