with a standard rb25 head, external gate

what is the max boost it should run?

what revs can I expect full boost?

about what power?

the workshop is recommending against another china turbo against my better judgement....

On a 2.5ltr i ran 17psi 270-280rwkw and it was on by 4000-4200rpm.

370rwkw on jungle juice @ 24psi... lots of room to move.

18-20psi with a 3ltr you should see ~330rwkw on PULP without a drama.

You'd take a rough guess it'll be on nicely around 3300-3500rpm with a 3ltr.

Lets see your china turbo do that you tightass accountant :thumbsup:

ive got a cheap china turbo on ny 30 atm (TO4e with a 0.62? rear) make 14psi by 2000 but then drops down to 10 as its physically chocking the exhaust. still makes 230rwkw at 10psi though.

im getting a GT35r for it now :thumbsup:

yeah china t04e is what I am running now. 260awkw @18psi. full boost at 2000. external gate, it holds boost perfectly all the way.

they break a lot which doesn't worry me...but the mechanic is trying to talk me into something more expensive.

hmmm. sounds like you done the same thing for the same reasone i have. its weird that urs is flowing fine, as my tuner had said boost issues with mine (using the ViPEC for EBC). My tuner is also the one pushing for a Garrett etc

conspiracy???

try for a 3071?

a 3076 is seeing positive boost at 2000, so the 3071 should be better suited to your needs.

spend the money duncan by the time you replace your china turbos once a year you might as well have just bought a decent one :thumbsup:

yeah that's how the maths looks to me too....but I did commit to looking into something else. Strangely the turbo importer does not think they have to warrant the turbo when it fails ;)

Hi Duncan

I have one on the R33. You are welcome to try it out.

thanks mate....might do...standard capacity, head and cams right?

Get a GTT highflowed by Gcg that should do it.

I'll check out 3071 and hi flows I guess, maybe gtrs. I was assuming the hi flows and gtrs would be a little small on a 3l even for response, maybe not.

I wouldnt use a high flowed GTT turbo by GCG as the main benefit is the standard exterior for legal reasons. Sure its a reasonable turbo but for the cost of over $2k you can get a much better turbo.

I would be careful that you dont completely strangle the engine with a restrictive turbo, I wouldnt go any smaller than a 3071 on a 30. How bout a 3071 with 0.63 housing? That would be ridiculously responsive.

Standard RB25 cams etc (but HKS cast manifold). It would give you an idea of how it delivers power. Obviously the extra cubes is offset by the extra weight of the stagea so I would be a fairly close comparison.

I'll pm my number.

are you using a standard manifold??(exhaust) . i got a cheapy kkr 560 but was a rip off of one. im using an external gate (progate 45 mm on my 30)because the original one is opening at 20 psi. garret gt30/40's are now known as gt3082 .

Its got a china stainless zorst manifold and china front facing plenum as well.

From looking further there must be at least 2 or maybe 3 different turbos called 3040 because people mention .63 all the way to 1.02, and peak power ranges from 270 to 330. If I go one of these I'll make sure its the smallest one.

still looking into another china turbo too.

      I've watched some vids and the technique seems to be to butt the sheets up to one another and use MIG to spot weld and slowly fill in the spots until its eventually all sealed. No runs as you would normally do, as there's too much heat generated that way. Yeah my stick welds are terrible these days because its been so long since i've done any of it. I expect to be spending many hours practicing

      I have personally seen a Tomei USA RB26 cam that didn't even fit the head. Kind of nuts to me that it was even possible for that to happen but such is life.  There's two UP Garages in the US. One is a US branch of the Japanese company which sells things they brought over at tremendous markup. The other is University Place Garage/Fairlady Motors which is a shop best known for putting VCAM in RBs and trying to convince people to stop putting in 800hp of turbo on a 2.5L motor.

      Gasless MIG is not exactly suited to what I would call "delicate" or "attractive" welding. So I would rule it out for sheet metal rust repair type stuff, unless you're only doing it in hidden places. I'm thinking about getting myself a gasless MIG for "hack together" type work. Noting that my welding experience is very very low, and quite a long time ago. So I'm also looking for "simple", but I'm not expecting "excellent". I'm not even sure that proper MIG is the best for sheet metal work. I get the feeling that the degree of control and the minimisation of heat input that you get from TIG is probably what you really want. And then you have to get good at doing it before the welds won't look like a monkey flinging a handful of shit anyway. You're probably SOL for an easy and cheap way to get from where you are to where you want to be. Much like myself.

      Any recommendations for what would be the easiest welding type to start on, for sheet metal rust repairs and maybe some exhaust piping too? Seems like MIG is the most common. Would gasless MIG be ok to learn on and do some simple jobs? I have a stick welder which has a Lift TIG setting, but i'm more interested in getting whatever's easiest to do, and most suitable, rather than using what i have.
