hi all, I have a couple of questins regarding a hi flow turbo that i am considering buying (i have a lot to learn when it comes to turbo's), I only have a certain amount of information at this point about the turbo but the rest of the info will be made avalible to me as soon as i know what questions to ask.

here's some info on the turbo:car was taken to geebung drift king with blown turbo. they removed it and sent it off to Garrett to get it rebuilt. apparantly its a pretty custom jobby. 300zx turbo housing high flowed with steel wheel, rb25 compressor housing high flowed with steel wheel. (there are recipts for the work done on turbo)

would a a 300zx rear on it make it spool quicker ?

at this stage i am assuming it was origionally a R32 stock turbo at the begining, will this be a straight bolt up to my Rb25det?

will it be a better than my stock R33 turbo?

my stock turbo comes on nicely a 2000rpm and currently running 12-13psi daily

reason for buying this other turbo is so i can happily run it at 1bar daily,if and when i deciede to get it out on the track i will be happy to wind it up to 18psi and have my stock turbo laying around as a spare, i would appreciate any constructive input and answers if you have them, if you have any questions u think i should put forward to the owner please let me know, cheers Damo

shirt answer is YES. it will bolt on and be an upgrade.

Long answer would invole you answering more questions which you won't know the answers to as you are not the workshop who took it apart and measured bits.

that depends matey. The is it the 300zx twin turbo? or single turbo. The twin turbo one is no good.

Only the single turbo one - also known as the vg30det turbo - not the dett

I hope/believe it is the single turbo. why is the twin one turbo no good?? thanx in advance Damo

the twin turbo ones use a t25 flange (and are too small for your car), the single uses a t3 flange - same as your stocky.

If it has OP6 on the exhaust side and the usual R33 compressor housing it might just be an R34 turbo thats been rebuilt.. If hat has been hi flowed and rebuilt with steel wheels ur laughing. I recently bought a 34 turbo (stock) and it has the same VG30 rear housing from a Z31 3L single turbo V6 and same compressor housing as the R33. Basically the upgrade to an R33 RB25 turbo is it shoudln't run out of puf at the top. If urs is a hi flow u should see some good gains, bit more lag, more top end. Thats what it sounds like to me. A good indication of a hi flow turbo is the rear housing, If there rear wheel is large enough to come close to outlet maximum measurement its deffinately been enlarged.

      EFR7670 exhaust selection RB26

      By LegendGTR · Posted

      I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!

      OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
