hi everybody, recently running a project for my Rb25det and getting an idea of putting a T70 turbo with stock engine. the follow are the spec that i am planning to go for.

- nismo 550cc injectors

- 600x300x100 front mount

- hi-mount manifold

- 50mm hks style wastegate

just a question here, i am planning to push my car to around 400hp so is the spec capable to handle the turbo with A/R .80 ? what els did i miss out ? kindly seek for help.

Strongly suggest doing at least valve springs if not cams as well as the cylinder head is at its limit at around 285+ kw. Car will suffer from compressor surge and valve float at 7000+RPM. had this problem with two cars now. one running gt30/40, other running to4z. both of these cars are running Turbosmart wastegate 38mm,

sorry for late reply. well after consideration i have changed the plan. currently putting up a old school TD06 which is straight bolt on( the guy who sell to me said that). the guy claim that without changing ECU, Injectors, anf FMIC and apply standard boost will make 240rwkw. any opinion ?thank

the turbo may be good for 240 rwkw but there is no way in hell your going to get 240 rwkw out of stock ecu, injectors and AFM on an RB25... you need to upgrade all these parts at a minimum.. and then maybe run above stock boost.. to something like 1 bar.

TD06 ... if im thinking correct is not internally gated.

So definately not bolt on if thats the case. And depending on which version of TD06, its not going to be response friendly

Anything over 200-220rwkw requires as a general rule:

Fuel Pump

Z32 AFM

Injectors (or a slight pressure bump depending)

PowerFC or other programabble ECU

So i'd purchase them (costing around 2.2k-3k depending).

Then look at something like a GCG hi-flow (2k). So all up around 6k fitted and tuned. Awesome package then :O

      Fake ARP bolts?

      By GTSBoy · Posted

      Well, maybe not. The main feature of Chinese manufacture seems to be incredibly variable quality, coupled with an apparent willingness to find a way to see even the stuff that fails QC. So the military could still take the cream of the production run and somehow sell the "sellable but not really useable" stuff to the stupid round eyes on the other side of the world.

      Have you adjusted the clutch pedal rod? You can wind it in to shorten it. Just can be a cnut to get to.

      Fake ARP bolts?

      By TurboTapin · Posted

      Yes sir, that was me. Fake ARP's are also a thing over here in Canada and we only order from reputable dealers. It's sad that even simple things like bolts and hoses are now also being copied... anything to make a dollar.  Story time. Like all cheap crap from China, it's even an issue with firearms. Roughly 15 years ago, I purchased a new cheap Norinco 12g shotgun. First time out in the bush with it, while firing, bolt assembly didn't lock and it fired out of battery. The receiver also being cheap steel, basically exploded in my face. I was lucky to be wearing eye protection. Long story short, don't buy Chinese junk. Also Norinco being state run and their only military arms producer, if ever they do try and take over a country, don't worry about it lol.

      Nismo copper mix twin “pull” pedal height engagement

      By ck_chino · Posted

      Installed  Nismo coppermix twin competition spec last year in my bnr32 with pull trans with Oem slave cylinder. The point at where the clutch disengages/enages is right at the top of the clutch pedal, meaning I barely have to push the pedal down for the clutch to be disengaged.  You guys that have the same combo are you experiencing this high pedal bite point??   Secondly I’d like to have the disengagement point lower meaning I have to push the pedal more(further not effort)for it to be disengaged.  I’m thinking to use a Nismo big operating cylinder(bigger bore at 13/16 vs Oem 3/4) which will require more pedal stroke to get the equivalent movement at the clutch fork. But I see Nismo web site says not to mix these 2 as the Nismo big operating cylinder doesn’t have enough stroke to disengage??? Any folks run both the coppermix twin pull with Nismo cylinder??    Thanks in advance for the replies but prefer only guys with pull clutches to respond. thanks
