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

$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

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

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

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

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

maybe i would if they didnt cost 2.4k, unless you're willing to pay for it?

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

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?

its going to be much more effort to get all the pieces individually and have a turbo made rather than just buying a kit ready to bolt in, on a td05 16g will the anti surge really make much difference? because its just much less hassle to buy the kit and bolt it all in and that kit by the sounds of things is perfect for me except for the anti surge part, my intake piping is already 3" so thats not really a problem either

as a complete turbo kit there is no non anti surge option, excuse my cluelessness but what is anti surge anyway?

what difference would a 2.4" compressor cover make vs a 3"?

Roy you wouldn't by any chance have the torque version of thode graphs?

the hks and garrett turbos arent looking a whole lot more responsive in terms of power but they boost up much faster than the other turbo's, and in the power graphs the garrett has got about 20kw's more than the hks turbo in top end, garrett turbo is definitely seeming like the way to go although i would like to find out more about the kinugawa turbos because if i can get similar performance to the garrett turbo for $400 less i'll take it in a heartbeat

How about a td05 18g or 20g? I'd rather not get a used turbo if I can and the kinugawa turbos are about 400 cheaper than the Garrett so if I can save that money I'd like to

they have a few different options, td05 or td06 in 16g 18g or 20g, not really sure what means what?

fair enough, while looking at some different turbos i came across this http://www.ebay.com.au/itm/Kinugawa-Turbocharger-Bolt-On-3-Anti-Surge-RB20DET-RB25DET-TD06H-60-1-T3-8cm-/271795646032?pt=LH_DefaultDomain_15&hash=item3f48486e50 would something like this have good response? much cheaper than garrett or hypergear options which would cover the cost for some cam gears

over 270kw out of an rb20

yes its my daily, i do plan on taking it to the track occasionally though

i dont really have a set budget although the less i spend the better, in terms of engine work i dont plan on doing anymore after the current things im doing to it, so injectors, afm, nistune, possibly cam gears and turbo

Well I guess that's cam gears added to the list, depending on how much they improve response I may be able to go for one of the hypergear turbos

i already have a front mount and run 98, does running the cams and cam gears together make the turbo come on sooner or is it just the cam gears? i dont plan on getting cams but if cam gears themselves can help response a little that would be good as they're relatively cheap

That's why I plan on getting it tuned with the rb25 turbo I have on there at the moment, if it's fun at that stage of power I'll probably stick with it for quite a while before going for a turbo upgrade

at the moment my car isn't tuned at all, by getting it tuned it will run nicer, i'll make a bit of power and ill have a dyno reading of what everything is doing, peak torque/power/boost levels, with that info i can select a new turbo with much more information to go on, i also never originally planned to upgrade my turbo until a much later stage anyway, i might even be happy with a lower level tune for quite a while who knows
