so at this stage im going to go for a td05 16g with a std 2.4" or 3" compressor cover, compared to the garrett 2860 this should provide similar response and power except $400 cheaper, or will it be not as god as the garret turbo?

I think it largely depends on how good those Kando Rb T3 housings work. The TD05-16G you describe is effectively a Trust T517z. The Garrett is effectively a HKS 2530. So if you spend a few hours reading SR20DET results using a T517z vs HKS 2530 you will get an idea what you are getting yourself into :)

EVERYTHING is a compromise! You need to decide for yourself what compromises you will live with based on what your desired objectives are.

i think i may end up going with the garrett after all, it is slightly larger overall but its ball bearing vs the kinugawa's journal bearing so i'll be getting a similar response overall with more power, i guess thats why its an extra $400 haha, and if the garrett really is essentially a hks 2530 then on every single thread ive read the hks turbo is the best thing for an rb20 so i might just go with that

ive heard plenty of stories with second hand turbos that have put me off them haha, or just but the garrett for $1400?

That's for you to decide isn't it....

Heaps of people have no worries with second hand turbos. Obviously there is a risk though.

unless hks decide to suddenly have a 50% off sale then at this stage garrett it is, i dont have a problem with second hand parts as long as they arent something major, but with a turbo i just dont want to run the risk since it can have large consequences so i'll be going with a new one

the garrett is the exact same as the hks, roy posted a graph with several different turbos on rb20's and the garret and hks had almost identical spool rates and peak boost levels, and its 1400 as opposed to the more expensive hks, i'd prefer not to get a used turbo as there is always the risk of it being shit

I don't think they're exactly the same...should be pretty close but the HKS might be tweaked a bit.

The more important aspect is that the HKS comes as a kit with everything you need should you buy it new, hence why it is a good value and worth the money.

I don't know anyone who has bought a HKS 2530 who has said "gee I wish I bought a cheaper turbo!" or anything like that.

they are almost identical in terms of basically everything, i have not found a hks turbo with the kit for any less than $2200 so i dont know where you got your $1800 figure from, and i've just found the garrett can come with a kit for an extra $200, making it still $200 cheaper than your $1800 value anyway, and you're talking like anything but a hks turbo is garbage, last time i checked garrett is one of the best brands out there, but then again you're a guy willing to spend $250 on a second hand hks dump pipe so by the looks of things you're a hks fanboy who thinks everything else is crap so your advice seems pretty pointless and useless honestly

HKS IS Garrett. Just with some unique-to-HKS (but still made by Garrett) housings and wheels. The quality is exactly the same.

Back when the 2530 came out, Garrett were not allowed to put out a turbo using the same stuff as the HKS turbos had. But that agreement would have expired years ago, hence Garrett have been able to put out things which are not much different from the old HKS products.

There are multiple versions of the 2530, the 2530kai (the current iteration) is a pretty recent product.

Garrett makes HKS turbos. But the HKS turbos are not exactly the same ones that Garrett sells themselves.

The HKS 2530kai is specifically designed for the RB20 and RB25DET. The Garrett ones are universal.

I am willing to spend $250 on a HKS dump because that's what they're worth, but I found one in Japan. I am using it to test the difference in response between the Tomei one and the HKS one.

If you want the best suited turbo for the job you'll buy the HKS one as it is designed for this engine with a smaller housing for better response. If you want to save a few hundred dollars go ahead but don't come here complaining when it doesn't have the same response as your stock RB20DET turbo or RB25DET turbo.

Amazon Japan sells it new as a kit for $1885.64 USD right now. Go get someone to buy it for you.

$1885 USD = $2462 AUD and this is an australian forum so it would be a good assumption to make that most people here are from australia, on the graphs roy posted the garrett and hks had the basically exact same spool rate, peak boost, with the garrett having more top end power as well, now both cars could have had different modifications but both were rb20's and you generally cant change the spool time of a turbo unless you increase capacity, it simply makes no sense to spend $800 more on a turbo which will spool up at the same time, make the same power and is of the same quality, unless of course you genuinely like throwing away your money pointlessly

Judging by the graph the HKS has slightly more low down power whereas the Garrett has more up top.

Which makes sense as the 2530 was tweaked to improve response on RB engines.

If the difference isn't worth it to you that's one thing but clearly the 2530 is slightly more responsive so at the end of the day it depends if you want low end or top end.

in the graph the hks has more power off boost until about halfway spooled, and between halfway and when the turbo is spooled up they have almost identical power, keeping in mind the garrett turbo is running less boost as seen in the bottom graph, $800 for about 100-200rpm more responsiveness is simply not worth it, especially considering peak power was 10-20kw's more than the hks with less boost

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
