  1. I sent an R33 block and an R32 block approx 12 months ago to be tested. 2 months or so passed and I got 2 reports sent back one of the R33 Block and then one of a R32 serial numbered block which had good results, unicorn spec. OK great I now can move forward and use good block as basis for build. Herman advised a mix up happened and that they needed assistance in identifying my block. I was shown a picture of a room filled with blocks and plastic tags, alluding that this is where the problem lies of finding my block. Later I was offered a swap of 2 of my blocks for a very good block, I simply offered to buy the very good block and bizarly was advised this is not possible and it's a one off deal kinda thing. 8 months passed and clearly the block had been lost or grown legs into another engine bay. Herman asked me to stop asking and advised that he does not like being hassled. Around a year onward from reception of my blocks, I received two blocks back , my R33 one and then instead of my R32 one, I received a mystery R33 block with tag "May be this one" and a test result with a date 2 years ago, pre-dating when I first sent my pallet of blocks.
  2. Just chiming in I also have noticed that quite a lot of high power GTR's have run N1 blocks yes ones everytime I spoke to an owner I noticed they had the N1 block. Seems that Facebook post oddly was removed, important information it was. I also remember at a similar time posting a question there which asked -- For every 20 or so high power cars on standard and N1 blocks, how many cracked?. Immediately Herman PM'd me demanding I stop asking baited questions. This was so bizarre. He also advised that he doesn't make any money on the $6-$8k PRP prepped cast blocks and it's such hard, messy and heavy work, and that it's a privilege to have one of them, which was the most bizarre thing i have heard. I Sent Herman a R32 block to get tested then 2-3 months got a report back with an early production serial number saying it was a Unicorn Spec 1500hp one, I then got told there was a mix up. During this time I got advised there is a great block with great test results I can buy if I like. 8 months later of asking where my block is, i got a pallet back with an R33 "61xxx" serial number block returned with a tag "May be this one" with report of a lower spec test results, what a joke. I'm going a Billet block I see better value
  3. I did a Step II with 9:1 comp pistons and there was a good amount of clearance, the go was to mock it up and advance the cam 50 degrees one way see if engine is still non interferance and then 50 degrees the other way and repeat on the stand I was not going to risk guesswork at all Yes now I have Vcam Pro going for 10:1 comp pistons and the go was to get custom pistons made with a dome shape that doesn't interfere where the valves normally travel to
  4. How much timing are you running in the top end?
  5. I purchased a few EFR's and yes quality kept going down with every purchase. Out of 5 EFR turbos every turbo had some sort of defect in the same general area however the 8474 was totally unacceptable / dogshit . They were distributed by various official BW distributors from Australia, UK and USA some purchased directly, others through online resellers. Most recent purchase 8474 was the worst. Some of the turbos had loose shavings and ends were extremely thin like foil It's been a while but basically the response I got was to the effect of - We or I can see it's understandably disappointing for yourself however the part works typical bureaucratic stuff.
  6. Hello. I am using a R33 GTS-T shell to mock up a custom turbo kit for my GTR, as I'd like to keep the GTR on the road while I make the turbo kit i'm using a GTS-T R33 Shell as a template. I'll fit a RB26 to it however what I want to know is whether the GTS-T subframe will clock (angle) and position height wise the RB26 the same as a GTR subframe. I'm unsure where the differences in GTS-T to GTR subframes lie, I assume it's in the drivers side for the AWD component clearance. Cheers
  7. 8474 didn't deliver anything special in my application, 2.8L high comp RB26 2.8l. WIth a 1.05 rear, compared to the 9180 it behaved very similar. It was quite more eager to come onto power faster on full throttle in 1st and 2nd gear, but it felt so restricted as soon as you got it moving. The 9180 didn't feel like it was choking the engine as much, overall felt much more healthy and a better match The 9274 was the next turbo I was going to try, but it looked like it would just be an extension of the drawbacks I had with the 8474. 74mm wheel simply too restrictive to swallow all the flow the larger compressor can give. Wasn't impressed with the 9280 from very limited testing I done
  8. I have a new Series 3 box, haven't broken anything yet with around 700hp, I go easy into 3rd gear. Have been tossing up about the sequentials. Lately the word has been PPG = probably not, a few people who've had them haven't been too satisfied with how they hold up A few big HP GTRs have switched to Samsonas and handling the power well. Albins seems quite new to market, unsure how good they are and how they handle the power. Big money to drop on a gearbox. I'm tossing up between Samsonas and Albins but will definitely want to know what's got the better track record on holding the power
  9. block brace is a good idea if you want to push for more power
  10. Speedflow hoses suit BW EFR turbo when used on 6boost manifold, removed from RB26. The short hose is used when a small dash fitting is welded to the factory hard pipe near the cam cover, it gives it a nice OEM look From the front. You may require an adapter on the block or turbo. Cost me about $350-$400. Sell for $100
  11. Stainless Dump pipe suit BW EFR 1.05 rear housing mounted on 6boost T4 manifold Removed from R33 GTR, RB26 Great for somebody planning an EFR Single turbo conversion. $300
  12. Red line is 9180, Blue line 8474. From limited street driving I can't tell a real difference at all in most conditions, no turbo is the clear winner but im inclined to feel the 9180 better suits my engine so far. I'll do some more testing with high lift cams and a 9280
  13. My EFR9180 and EFR8474 on 2.8 with Vcam Step II / ex HKS 272 8.7 Absolutely visceral to drive
  14. Hi Guys. I'm putting together my 2.8 engine. The exhaust will start off with a HKS 272 10.2mm lift. Eventually I wanted to experiment going with very big lift, such as JUNS 272 which has 11.35mm lift. I can only imagine to get that lift, the lobe will have a more agressive ramp and get more lift earlier in the duration. This question is for exhaust only as I won't be playing around with the intake. So far I had been under the impression high lift with same duration only ads benefits and no drawbacks. Can anyone with experience with this add some input?
