hey guys just a question, when i reach about 5 and a half revs on which ever gear my car tends to lag, not goinng its full performance is it the turbo or is it that not enough fuel is going through therefore theres a problem with the fuel injectors??.

thanks

hi newbie here

just wanna ask when does the turbo open/on/operate on a R33 S2 stock.. tnx

Turbo opens/on/operates all the time, when you see boost all depends on the Amount of Throttle and the amount of Load on the motor (In gear, not free revving) this will change though and you can add the size of your fuels system, intake, turbo, exhaust blah blah..

tnx sir.. its a very helpful info.. tnx

turbo will boost from 2000-2500 rpm - hopefully hit full boost around 4000rpm - 4500rpm up to 6500rpm (roughly)

(assuming stock ecu / stock turbo etc etc)

so before 2k rpm the turbo is doing nothing? is that right? also if the car got an intercooler it sure got a turbo right?

please bear with me.. totally newbie! tnx

apologies to the OP (dont mean to hyjack the thread but i feel compelled to answer his question as we were all newbs at one stage)

before 2000rpm the turbo is still running although its not making positive boost pressure.

in regards to intercoolers - generally yes - although u do find some people (i have no idea why) putting intercoolers onto non turbo / non supercharged cars.

if you have any other questions, just PM me - saves cluttering this thread up as its a bit off topic.

Turbo lag means the period before turbo hit its set boost. So if you have a really big turbo you would experience lag before 5500RPMs. Can you detail this lag that you are experiencing?

wrong. boost threshold is the minimum rpm required to reach target boost. lag is the amount of time it takes to reach full boost after planting the throttle above the boost threshold. getting technical but you should know this :laugh:

    • 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
