So i have a 2002 r34 gtt and i took off the stock turbo and bolted on a new turbo (link for turbo at bottom of post) and did a nice job of the pipes and hoses, made sure oil was running through the turbo nicely before starting, had to slightly rotate housing during instal i dont think that caused any issues such as the fins not spinning and started her up and went for a drive

I was absolutley gutted the car drives like a non turbo and iv notices a rattling sound coming through the exhaust any advice would be greatly appreciated.

Have you checked the shaft spin s freely by removing the intake pipe by hand?

It is not really a high quality turbo so the is a chance it Is a dud.

Edit.. It's scary they say you can use stock oil feed line. Bush bearing turbos need more oil flow, as the ball bearing turbos have a restrictors in the stock oil feed line, so it is very likely the turbo is not getting enough oil flow.

These TRS4376S Hybrid turbochargers are able to produce 480 hp equipped with the right supporting modifications

if you dont have any it will run like shit. you need an ecu and a tune at the very least.

ok so the Oil Feed in the new turbo has a restrictor bolt inside with a tiny hole and the bolt i used that came with it has a 3.4mm hole but it hits the inside restrictor.

il get the pics up in an hour, but i hooked the charcoal cannister to the plenum which goes onto the boost pressure sensor and theres a T at the cannister end that goes to the motor, maby powersteering?, as for the turbo outlet and the wastegate T's into a boost pressure solenoid and another hose comes from the solenoids top that goes nowhere atm i think its a bleed hose? maby it was hooked into the original frontmount pipe?

you wont get f**k all. stock exhaust? stock dump? stock ecu?

if it does come on the ecu will shit itself and not know what the f**k is going on.

pop your stock one back on, buy the mods first, install them all trailer car to tuner and tune it.

then itll work.

oh for real?, i was certain boost was atleast supposed to come on

It should work but not ideally. Should still boost.

I put on a garret 3071 and drove it for two weeks (gently) before i had time to tune it. Even a little boosting, but obviously taking it easy.

Unless the wastegate flap somehow came off the actuator arm i would be worried the Turbo is dead. I would also be worried it's not getting enough oil.

That's not true at all. As in previous post I should add I was still running stock exhaust and the car boosted fine with a 3071. Obviously I didn't hammer the car, but it definitely worked and definitely made boost.

Turbo went on first as I had and cess to a mates hoist at the time which made it heaps easier to do it t then.

Im off to diagnose with 2 mechanics soon il repost if its shat the turbine whats a good turbo reccomendation, anything bolt on by any chance? do you reckon the engine is taken damage from the turbo failure? i drove about 10 mins

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
