I sense a lot of pud pullin going on with regards to HTA's too, they are not magical, there is no fairy dust inside.

Failure of ceramic bearings causes many butt hurtz though. Come at me when you see one crack 200,000ks Lithium, then we can discuss how good they may or may not be. My opinion is already forged by my experiences. ;)

I shall re-iterate my :D

Never said anything about fairy dust, like anything it's all about matching components in a setup - the mood of this whole thread is basically identifying that fact. There are *some* HTAs which are very well suited to some requirements for RBs, and a lot of the time they are overlooked - which is the only reason they come up. There are also GTXs which work very well, when combined with the right setup - I'll give them credit. I "pud pull" over anything which I believe is capable of providing a particularly sharp combination, it's nothing specifically about HTAs... unless you count the fact there are quite a few of them which are better matches between compressor, turbine, and to the engines we like- or at least should like if we're here as enthusiasts.

I know of HTA failures (as with GT, GTX, EFR and basically every type of turbo I know of people using) but on the same note, none of the guys I know directly have had one. A mate had an HTA3586 which he first fitted to his EVO in 2008 which was used for drags, time attack, off road sprints and street use and is now on an RB30DET (which I've referred to in the past) and the EVO guy replaced the HTA86 with an HTA82 for a bit more response. Both of these cars are built and used properly, and have been for YEARS, and are both very strong performers, and are a lot of the reason I am pretty convinced by these things performance. So, I've not specifically counted kms but I know ones which probably had been thrashed as much (or more) than your GTX has yet had thrashed before your GTX was even available to be bought, provided better power versus response than a GTX3076R will, and are still going strong now.

Regardless of all that, yes - your point is right - the HTA (and shock horror also the GTX etc mentioned) in the post are more expensive than the T67s, and they aren't proportionally better performing, but to expect that ... let alone to focus specifically on one and not the other, is below anyone who isn't a blatant troll. At the end of the day we decide what we want to spend, what we think we're going to be happy ending up with, and decide if we can find a balance which is worth it cost wise versus result wise, unfortunately the cost goes exponential as we strive for better overall performance.

The old T67s are by all accounts really good units, especially for their price - different people have different views on what is acceptable so it's really hard to have this kind of conversation with people, one person might find the lag/operating rev range of anything worse than a GT2835 unacceptable and on the other hand I know people who find T51R's perfectly acceptable. Two T67s however, that's a whole pile of silly haha.

On that we can definitely agree.

Will be interesting to compare this BW turbo with the GTX45 builds I have coming up... Hopefully it lives up to the hype. :)

We don't agree on everything, but it feels sporting and at the same time I don't think we're on different pages either :D

EFR9180? That is certainly not going to compare with a GTX45, a GTX4088R (or really somewhere between that and a GTX4294R) would probably be the closest comparison you could get from the Garrett line - but still be very interesting to see how it performs!

^ Agreed.

Although I would have thought Super 94 and EFR9180 would have been a closer match... Either way, BIG power setup! Looking forward to some more EFR results!

      "Cheap" bolt on turbo on RB25DET NEO

      By tylink720 · Posted

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand

      You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
