Hks Gt-rs Id Tag No's ?
discopotato03 replied to discopotato03's topic in Engines & Forced Induction
Looks to be 446179-0067 for GT2871R / HKS GT-RS 52 trim . -
Cubes are your buttons sintered bronze or sintered iron , ie gold colour or grey iron look ?

Gt28rs Onto Rb20. How Hard Is It?
discopotato03 replied to Psymon's topic in Engines & Forced Induction
That Turbo assembly no 707160-10 or -0010 on my list shows the CHRA or cartridge no as 446179-0067 . I also found the GT2535 cartridge no 446179-0019 , its assembly no is 472560-0005 (.64ARR) and -0006 (.86AAR) . There are six turbos in this group , aplications are all HKS . They are in the GT2560BB section . 472560-0001 446179-0017 . 64 ARR 472560-0002 446179-0017 . 86ARR 472560-0003 446179-0020 . 64 ARR 472560-0004 446179-0021 . 64 ARR 472560-0005 446179-0019 . 64 ARR 472560-0006 446179-0019 . 86 ARR Cheers A . -

And so would Stu Wilkins amongst others . Anything shorter than 4.375 is now rocking horse`do do . Stu searched world wide for 5.1 and 5.3 with no luck . I remember seeing one of the last brand new 5.1's before it went int a Zed rally car . I think these two ratios were Nizmo options not used in any production vehicle . Cheers A . P.S if that 3.7 had 12mm bolts I'd buy it off you ! -
Hi all , I thought the R32 would be a good road car for a 3.1L but I'm beginning to think the R33's comes std with more of the right bits eg gearbox . The R33 PFC's are easier to get and std brakes are pretty fair ? I'm told the engine bay is not as "full" as an R32 so the spannering would be easier . The thing I don't know is how much heavier the R33 is which of course relates to power to weight and fuel consumption . Handling wise whats the opinion of those who've spent a bit of time in both - road remember not circuit or drag . Another thing is the R32GTR's had a wider rear track than the RWD car's , is it the same deal with R33GTS25T and R33GTR ? I get the feeling that 33's have a greater following here and parts availability is a bit better . A little voice keeps saying the 32 was the homologation special so what to do ? Life is always at a crossroads , cheers A .

Gt28rs Onto Rb20. How Hard Is It?
discopotato03 replied to Psymon's topic in Engines & Forced Induction
From my list the cartridge no 446179-0032 uses the NS111 turbine in a .86 ARR GT28 turbine housing . Its compressor is a 71.1mm 56 trim GT35 in a .60 ARR comp cover . In short its been called the 56 trim GT2871R and goes under turbo assembly no 743347-0002 . Garrett also do a very similar thing but with a 48 trim compressor under cartridge no 446179-0031 and assembly no 743347-0001 . The HKS GT-RS fits in between with its 52 trim compressor and same turbine , it generally uses a .64ARR turbine housing in T28 flange or HKS's T3 flanged housing with outlet to suit the RB20/25 . If anyone has a GT-RS handy I'd like to know its ID tag numbers as well for future reference . The 446179-19 is apparently the cartridge no for the HKS GT2535 , which uses a 69mm diametre compressor . Cheers A . -
Fj20 Piggyback Computer?
discopotato03 replied to NeoLokie's topic in Classic & Vintage (1950's-1980's)
I think Mines did a modified ECU for DR30's . Sounds hard but if you could adapt the CAS to an early SR20 signal you may be able to use the SR loom and ecu to run the engine then substitute an Apexi PFC . The early Red Top SR20DET I think still used a distributor so its optical disc may fit . With PFC's you can generally change to higher flowing MAF's , Skyline PFC's can use the Nissan Q45 V8 AFM so it's worth a look . Cheers A . -

Matty I'm curious to know the ratios of both of those as most differential manufacturers have a different offset somewhere in the middle of the ratio spread . I can't remember with R200's but I think it may have been around the 4.375 point . Anyway is not generally a drama as theres heaps of latitude for correction , my old H190 with the Detroit locker used an approx 100 thou (2.5mm) spacer plate as its offset was intended for the 4.625 ratio which was the change over point in H190's . R200's are much better than H190's because the spacer rings or shims are on the outside of the carrier bearing races not the inside (pulling bearings off to select fit shims is a time consuming pain in the butt) . So the spacer rings can be used to a limited degree for changing offset (as well as setting bearing pre load) . The really difficult situation is where the carrier with the lower range offset is used with the higher range offset crown and pinion as there is no way to move the crown wheel far enough to get it in next to the pinion . I don't know if this makes any sense to you but understand that every different ratio will have a slightly different crown wheel thickness . This is because the number of pinion teeth change and so must its diametre . There's no whay Nissan would have a different main housing for each ratio so the crown wheel thickness was varied to allow the difference . R200 ratio's ranged from around 3.1 to 5.3 , the tallest having the lowest no of c/w teeth and highest of pinion teeth and the shortest vice versa . The carrier flange offset changed in the midst so that taller ratio c/w's would not be too thin . Cheers A . -

Race Spec I was looking for the cartridge number which from another string is 446179-19 or maybe 446179-0019 . Was the one in the pics a Garrett marketed turbo or a HKS ? Also that one looks to have the Nissan/Garrett style compressor cover rather than the Garrett T3 barb style shown in HKS catalogs . Again thanks A . -
Thank's BigDatto . Cheers A .

Whats The Number For A Standard Rb Turbo?
discopotato03 replied to lows_13's topic in Engines & Forced Induction
Made by Hitachi not Garrett . -
Fair enough , I just like the Pro S housings because their a bolt on and could look vaguely std - sort of self contained . For me external gates are a bit much for the road but I'm a bit conservative and look to simple answers where possible . Cheers A .

My Radiator Finally Has A Crack In It.
discopotato03 replied to george.bryant's topic in Classic & Vintage (1950's-1980's)
The question here is do you want a radiator that really works and doesn't weigh a ton ? I looked into multi row custom made copper core rads and they were more expensive , much heavier , and don't cool much better than the std rad . Your call . -

True but open R200's are still around and the 12mm bolt type is the best option here , why Nissan went that way with Turbo DR30's , R31's etc . Once you have the LSD carrier the rest is pretty strait forward . You need to find a mechanic thats been down this road many times and knows what what . -
2535's would be a little less laggy than GT-RS's , their compressors measure 69mm where RS's are 71.1 so a little less innertia all else being equal . Cheers A .

There are different versions of the GT3071R , 3 from Garrett and I believe 3 from HKS . Basically they are all GT30 turbine based and use one of the three available trims of the GT35 compressor . The Turbines are mostly 60mm (GT30) and the compressors 71mm (GT35) hence the name GT3071 , the R means rolling element ball bearings . The main issue with this series is the exhaust housing because it locks you into a mounting flange size ie T3 or T25/28 . It also forces you to choose integral or external waste gate . The single turbo RB exhaust manifold is T3 flange and unmodified assumes you'll use an integral gate turbo . HKS has tried to make it easy (if expensive) by selling the GT Pro S turbos (2835's and 3037's) with a T3 flange integral gate housing . I think we can assume the two available Pro S ARR sizes (.68 , .87) are aimed at RB20's and RB25's respectively . The confusion exists because at some stage Garrett decided to crop the 60 (59.9) mm turbine down to 56.6mm in order to fit it inside the GT28 (T25/28) flange exhaust housing . The in between hybrid or cropped turbine does not work very efficiently with the GT28 housing but allows for a simple bolt up solution for manifolds with the T25/28 flange (eg CA18DET , SR20DET) similar or same exhaust outlet too . Garrett calls their GT3071R with the cropped turbine and GT 28 housing "GT3071R wastegated" . They do 2 versions of it . 1) Turbo no 700382-0003 with hybrid turbine 84 trim and .64 AAR GT28 housing . 2) Turbo no 700382-0020 with hybrid turbine 90 trim and .86 AAR GT28 housing . They also do a version with the full sized GT30 turbine requiring a GT30 turbine housing . You can buy HKS's Pro S exhaust housings separatly and turn this last one into something that bolts to your T3 flanged manifold with the integral gate . The HKS GT 3037 Pro S turbo uses a 60mm GT30 turbine and its this housing that will fit the propper full turbine sized GT3071R (cartridge or CHRA no 700177-0023) . This may not be the cheapest or easiest option but from an engineering point of view it gives the best chance of success in this series . For a similar but slightly greater result you could always try the 52 trim version of the HKS GT 3037 with the Pro S exhaust housing but I'm not sure if HKS market that particular option , someone in the US may be able to mix and match for you . Adapting a T3 to T28 flange is always the last option and a definite compromise . Cheers A .

discopotato03 replied to Psymon's topic in Engines & Forced Induction
Racespec can you show the ID tag of that turbo as the HKS GT2535 has an unusial 69mm compressor wheel . Also the RB25 or VG30 BB housing is worth a go as the .86 GT28 housing is a high flowing item . Thanks A . -

discopotato03 replied to Ghostrider's topic in Classic & Vintage (1950's-1980's)
12mm bolts are not an issue as the carrier or hemisphere does not locate on the bolts , simply drill the holes larger ie 12.5mm . The hemisphere locates on the large inner hole in the crown wheel . Cheers A . -
As far as I'm aware the only Garrett housing is a GT28 with T25/28 flange for the 90 trim turbine . The .63/.82/1.06 T3 flanged Garrett housings are for the 60mm GT30 turbine , need the GT3071R 700177-23 cartridge (CHRA) for them . Cheers A .

ECR033 it sounds like you're turbocharging an NA RB25 with its higher (10:1 ?) CR . IF so it becomes more sensitive to back pressure (heat + reversion) so a turbo biased toward low exhaust restriction becomes critical for it not to detonate to death . In this case the GT3040R is bad because the compressor (82mm GT40) is a bit big for its 60mm GT30 turbine - sort of biased wrong way round . Arguably the GT 2835 Pro S missed out on a bit of turbine efficiency with its cropped turbine , there is a similar version offered by Garrett called the GT3071R which uses an unmolested 60mm GT30 turbine cartridge no 700177-23 . The thing I don't know is how well the cropped turbine works with HKS's purpose made exhaust housing . Its a bit lame when used with Garretts GT28 .86 ARR housing which I believe is overbored beyond the 54mm it was designed for . I think the HKS Pro S style housings are based on the GT30 or 60mm turbine dimensions and cope ok with the cropped 57mm turbine . I would be costing the real GT3071R with plain .50 ARR comp housing (T04E) , and one of the two available HKS Pro S GT30 housings from their 3037 Pro S in .68 or 87 . Don't forget the cost of the waste gate actuator as well . The 2835 Pro S is at least designed to be a bolt on and comes with the actuator . Someone on this board recently got one though with the .68ARR turbine housing and posted some pics so do a search . Cheers A .

Gt28rs Onto Rb20. How Hard Is It?
discopotato03 replied to Psymon's topic in Engines & Forced Induction
Very similar cartridge , same turbine . 2530 uses 60.1mm 63 trim compressor where the GT28RS is 62 trim compressor with a bit more tip height . It is a later evolution of the 2530 . Turbine housings , 2530 uses RB20/25 specific .64 ARR T3 flanged housing . GT28RS uses a generic type T25/28 flanged housing in .86 ARR . What you really need is the .86 housing with the T3 flange , an option thats not available . The GT28RS is the better turbo but its T25/28 flange will require an adapter to fit it to your manifold . The generic T28 turbine outlet is very similar to SR20 T28's so a decent aftermarket split dump pipe may get the job done . From memory one of the stud holes is in a very slightly different position , nothing a little die grinding can't fix . Alternatively a second hand 2530 housing will make it bolt on but the 28RS really does need the .86 ARR to work properly . Cheers A . -
Actually there is a couple of options in the GT30 turbine based range , just maybe not common or cheap . There is a version of the HKS GT3037 which has a 52 trim compressor rather than the 56 trim comp version which is the same as the GT30R . The 52 trim version comes with a .50 ARR non port shrouded comp cover (housing) instead of the 56 trims .60ARR port shrouded comp cover . 52 trim CHRA no 700177-0006 , turbo no 700382-0009 or -0010 56 trim CHRA no 700177-0007 , turbo no 700382-0011 or -0012 Second option is the propper GT30 turbine version of the GT3071R CHRA no 700177-0023 . This uses the 56 trim GT35 71.1mm comp and has the same compressor flow capacity as the 48 trim version of the HKS GT3037 but with higher efficiency and less innertia to accelerate . The GT37 compressors in 3037's (48/52/56T) and GT30R (56T) are 76mm . So two options , the 3037 52 trim and the GT3071R generally use the same type of comp cover so appear the same externally . Your call , cheers A .

My Radiator Finally Has A Crack In It.
discopotato03 replied to george.bryant's topic in Classic & Vintage (1950's-1980's)
Guys another option is the std R32 GTR radiator , I had the Koyo make in my FJT Bluebird and it worked really well -saved a HEAP of weight and its cooling was phenominal . You will have to adapt to spigot mounts but once you do it comes out with a screw driver (hose clamps) and a 10mm ring spanner (two top bolts) . It will involve two holes drilled for the top mounts and a couple of nutserts wich is easy . The FJ had a piece of exhaust tube with suitable bends to transfer water to the bottom rad outlet as FJ and RB are opposite sides , top is OK . Custom rads are OK but expensive to repair (recore) as they are literally cut open with a band saw . An off the shelf can be very convienent , particularly when its 1/4 of the weight and lightyears ahead in cooling efficiency . Given a choise I will NEVER use a copper rad ever again . Cheers A .
