hello all.

i know it is a bit of a noob question but i really cant be stuffed trawling through all the turbo threads to find out the following question.

which standard nissan turbo's are the same output as the std series 2 stagea as well as being the same fittings etc., but with steel internals?

for instance does a snail from an r33 rb25 fit up the same? or perhaps and r34gtt etc?

and was wondering if the turbo from a dirty old holden VL is the same fitment but with steel internals as i have been told?

only reason i ask is i am wondering how long my original turbo will last if i wind it any further than the 12p.s.i i have it set at currently and have been told that a VL turbo would be a direct swap and has steel innards.

if that is true i can get hold of a pretty good vl unit for $150 andwould like to know if its gonna fit is all.

cheers oxford

The VL turbo wont be roller bearing, nor will it be of comparable design as far as aerodynamics go. The trims are probably diferent on the housings and wheels too.

The turbo you have should last provided you dont have a crap boost controller that causes a boost spike to go over the 12psi. Around 14 is the absolute limit and above that your in the destruction zone.

i am running a turbosmart E-boost2 unit so it should hold no probs i just wanted to know the things outlined in the iniitial post but also how long would the wheels last if i were to run at 13-14psi?

also would i have to change anything to do with the wastegate settings or the blowoff valve etc?

turbos that i know for a FACT will bolt up to your stagea (becuase i have one of each at hte house)

r32

r33

r34

Y33 (VG30DET)

y32 (VQ30det)

stagea (obviously)

cefiro (refer to r32)

what are the relative differences in the units listed above if someone can answer?

for example are any of the steel internals as opposed to ceramic?

do they shift the rpm/boost band around either higher or lower, and if so which ones and which way specifically?

all this is in case mine goes tits up and i need to replace it quickly to return car to service, as iwould like to be able to have one ready to go if need be, and it would be a bonus if i didn't need to worry bout it smashing again if it were to be steel internals etc.

also wondering what a high flow would be worth to get done if i didn't need to do changeover?

cheers oxford

more or less, the R33 and R34 have ceramic turbines which are sensitive to temperature (and load). i presume much the same for the others however there are slight differences in the turbine housings. VG30 (single turbo) and R34 are the same size but compressors are different. R33 is slightly smaller turbine but same comp as the R34. (btw there are a few factory metal turbines but most are ceramic). the slightly larger turbine housing makes them a little more efficient and they MAY make about 10kw more due to slightly lower exhaust manifold pressure but maybe a hundred or two rpm slower to spool.

if you are going to change on the cheap, buy an R33 for a direct swap on a series 1 stagea or R34 turbo for a series 2.

generally prolonged loads over 12psi will lead to ceramic dust in the cat disease so leaning on the turbo harder is raising the risk. it might last 3 yrs it might last 5 minutes.

if you are looking to change then look at GCG hi-flows or HKS GT-RS as the cheapest (ballbearing) alternatives and onwards and upwards from there. remembering your old turbo is probably worth about $300.

arent r33 turbos identical to s1 stageas?

i would be interested to try out a VG30det or VQ30det snail.

The s2 R33 turbo (and engine) is what we get in the s1 Stageas, and the R34 Neo engine is what goes in the s2 Stageas.

When my turbo blew on my s1, I replaced it with an s1 R33 turbo, which has steel wheels. I noticed that it didn't spool up quite as fast, not go quite as hard, but I've never bothered to check if the wastegate actuator had been fiddled with previously on the original one that was on my car.

The blown one is (obviously) on the right, and the replacement is on the left:

    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car

    • I believe @Duncan has given it a crack at Mt Buller before (in actual race conditions)
    • All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.  
    • My steering lock unit on my Infiniti G37 has failed. The car is a local 2012 Infiniti G37 (Q60 ) I need to replace the unit My local mechanic said i need to buy a complete steering wheel assembly. Does anybody no any mechanics in Gold Coast or Brisbane who can fix this issue or where i can buy just the Steering lock control unit. Thanks
