    Add: Trent mentioned it is a stock engine and didn't want to push too much power out of it, so timing was backed off up top for better reliability or its going to hit 300rwkws.
  2. hypergear
    I'm pretty sure red is work in progress, I appears some thing didn't go according to plan all runs was backed off at around 6000RPMs. perhaps the owner of the car can add some additional information.

    Is that the O ring sits inside the gate and seals against the piston? I can make you one out of stainless steel for $60 express posted. Funny how many people have lost that part.

    T518 style T28 internally gated patterned turbine castings are available. re-make another wastegate port and disc isn't much of a problem. How ever those turbos don't perform an where near to what they do externally gated mainly due to its turbine wheel and housing design. Our current ATR28xx and ATR43xx Rb25det and SR20det internally gated bolton options are pretty mature, they would out perform most of TDxx turbochargers internally gated (and some externally gated). No point going over what ever already done. Do check them out for a bolton internally gated option. Our Billet TDxx series will be engineered for externally gated purposes.

    Some updates for the externally gated series: Great news as I've managed to find few suppliers whom can produce TD06, and T518Z housing and turbine wheel castings. We will have some of those housings brought in and finalize machinery work locally. I will also invest some time in making up CNC drawings for billet compressor wheels. By the end of this month we should have billet version of both TD05H 18G and TD06SL2 20Gs in T518z (T28) housings, TD06 20 and 25G in both 8cm and 10cm in T3x turbine housings. Price will stay competitive against Taiwanese producers, we will use our FNT turbine setups as well as custom wheel profiles archiving greater response with higher power level. All turbochargers will be made to order in strict time bases, great support and customer services as always, and we won't be blocking any one on ebay.

    Yes if you run a 4inch intake you will need to trim the engine mount. But I can machine the comp housing down to 3inch instead of 4. How ever it is still recommended to trim the engine mount and run a 4inch induction pipe. Since the engine is out, installation would be easy. I would just use the HKS manifold. I'm sure the end result would be similar or better to other aftermarket manifolds.
  7. hypergear
    Yes the G3, SS1PU or SS2 sits on in the HKS manifold fine.Its pretty hard to install if you are trying to do it with engine in the chassis. Also very tight clearance between the turbo to engine mount and drain port. The Brae manifold can be either high , low or side mount to stock position, I would prefer the side mount as they makes the power fine and nothing else needs to be changed.
  8. hypergear
    Check Brae auto fabrications manifolds. I'm using one and it performed well on couple of different turbochargers. also check drifthovc (Abe2) he's got a steam pipe manifold made with merged collectors for $600.

    I think Trent had few internally gated runs and they were no good. Had a look at some of the internally gated SL2 and even T518z on NS and they are no where near what they are externally gated. They are not some thing made to internal gate. besides all the Gx, SS1PU and SS2 units works well enough on ever manifold internally or externally gated, not much point re-engineer some thing's already been done. But having said that I will drop the billet TD06 into .82 type B rear for curiosity sake when I have some spare time. Or let me now if any of yous would wish to trail.

    Happened to current my r33, and I got around by adjusting the idle screw on the throttle body. Another incident happened to a R33 I've imported, that was from a loose timing belt.
  11. hypergear
    Since its going to take another 4 hours to re-install the brae manifold. I might do further evaluation. Using stock manifold, car made a one time maximum of 303rwkws with ATR43G3 none FNT turbo on pump 98. I will be install the same turbocharger back on and do one more run. Based on that I should be able to get the exact amount of gain if there is any. Plus I've already got the result with the same turbocharger running the China manifold, so we can compare against all three.
  12. hypergear
    That is 950
  13. hypergear
    I would use a ATR28G2 in a .86 rear housing. and for the link earlier it appears to be the same manifold. Mine has been coated before I bought it, it was from a guy in Aus.
  14. hypergear
    In car: Above is a China manifold, the one that I've had before Brae's manifold. and it actually worked exceptionally well and I've made 330rwkws of it based on a G3 on pump 98. This manifold is only $350 to get from China. It fits on stock position and bolt the turbocharger on factory position. This might be some thing I will be looking into in near future.
  15. hypergear
    Reason is when they do blow in middle of no where. You might have enough oil to drive your self out of trouble
  16. hypergear
    If oil feedline blocks then it will seize while drain blocks will cause turbo to leak oil from all seals. It looks like the feed is blocked. Check the line and drill out the oil restrictor in its fittings.
  17. hypergear
    Well that level of gain Its not worth the $500, a cheap china manifold would've gained better result. I won't be providing that service. mean while we also did a power and boost comparison using the current SS2 against the T67, both on E85 and ext gate (I need harder springs in mine). this is obviously not official just some thing interesting to look at. Red is from SS2 the rest are from T67.
  18. hypergear
    Think so. You need to run them externally gated to get the numbers. Also some results about aftermarket v Stock manifolds. Per last page referring to the modified stock exhaust manifold. I've done a back to back test today V Brae's exhaust manifold. It is actually more responsive as I've felt, however also down on power. Pink is modified stock exhaust manifold, while the other two are from using Brae's manifold. free flow manifold produced more on lesser boost, proper manifold is very necessary for power making.

    I've finally got some results sent in from our version of billet TD06SL2 off a S13 none VCT SR20det. It made 282rwkws on 18psi with E85 , it should just touch 300rwkws at full potential. This turbo is now available for $800 brand new for any one's interested. Far as I know the car has 264 cams with every thing else standard. And that is on a high mount T3 manifold externally gated.
  20. hypergear
    Just had a result sent in from a SR20det customer made 282rwkws. That is our billet version, don't want to hijack the thread, check out dyno readings on my thread.
  21. hypergear
    Check Plazaman's cooler kits. they cost bit more but they are very good at heat exchange. Had one on 24psi and the cool side end tank remain cold through out the dyno tune. Wither some of the cheap return flows coolers turned burning hot after couple of runs.
  22. hypergear
    A photo of the turbine wheel would be good. I've had few of their high flowed units came in for service, they were carried out using factory bearing housing, with cropped TA34 turbine wheels. if that is what you've got in your Rb20det high flowed turbo then yes it will be laggy, how ever it should be ok top end wise. turbocharger configuration for Rb20det needs to be treated as a Sr20det, Turbine wheel to any thing above the size of a 2530 will feel laggy.
  23. hypergear
    The Tube ID is 45mm Also an prototype actuator was made. it has adjustable rod that allows pre-loading, but also allow adjustments to spring load pressure. Similar to certain external wastegates that allows spring load adjustments. By using this prototype, I'm hopping to hold steady boost levels in upper rpms range, similar to an external waste gate result.
  24. hypergear
    That appears to be foreign object damage.
  25. hypergear
    There is a very noticeable gain in response using with this manifold. I'm very sure it has lesser volume compare to previous, plus shorter runners would've also helped. hopefully peek outputs stays the same. The factory manifold is a twin plus log manifold.I prefer keeping it that way, refer to previous photo, note the curvature in bends of both manifold logs. if that has been milled then exhaust gas will run into a flat end, its also the reason that I didn't mill into the merging point. External gate in this case can be attached to the turbine housing since the manifold is no longer restrictive.
