PM-R33

That's just stupid man, everyone knows you need to use zip ties to put 2 RB20's together. Noob.

Woooo hold up.....what you trying to say man? You saying you can't use a condom more then once *Runs to misses*

Wow i like that bonnet. However it looks in the pictures that the vents aren't actually functunal vents? Any reason you didn't make them functunal or are my eyes just playing tricks on me.

Wow What turbos? Twin 3071's or something?

Haha!

Does any one know this? We had a look and the R34 nismo ones have nismo etched into them and come in a nice little nismo box. My R33 ones have nothing on them and came in a poxy brown box lol

Pretty much the coolant running through the throttle body is to get the throttle body warm on start up due to places like japan where they have freezing weather (throttle body freezes shut). A lot of cars run this from factory to accomodate for certain parts of the world. Therefore in Australia it isn't really needed unless you live in a really cold place. So yes you can just piss it off and bypass it. You dont need to change anything on the throttle body and you can actually remove the ugly studs where the coolant lines go into with a bit of effort (did this myself). Now as too blocking the lines off, yes i believe you can do this, however i didnt just cause i didnt have my engine out like you and its really hard to get to that rear line. Just double check on this part. I pretty much just ran the line from the bleeder niple into the back of the block above the injectors and hid the line a bit. Let me know if you have any more questions bud.

Does the RB26 from the R32 run the same compression all the way to the R33 and R34? Most likely yes but i cant be bothered searching

So true, main reason why i got a forward facing plenum. Could not stand that cross over pipe and removing it all the time. Changing spark plugs when the car was hot was nearly impossible without majorly burning yourself. Why nissan couldn't put a modified GTR plenum with multiple throttle bodies on the GTST is beyond me. Surely it couldnt have cost them that much extra and would make the engine bay so much neater and practicle.

LOL, smart ass. My car is pretty quick for a whale so SHUT UP!! Love you man. For the detailing just use some good metal polish and paintwork polish and hit everything in the engine bay with it, comes up nice and new

And we're back....

Hell ill even throw some maths into this to prove that a couple of psi of boost pressure has no affect on cylinder pressures of an overall engine. Pre-igntion cylinder pressures are calculated by multiping the cylinder pressure at bottom dead center (one atm on our lovely planet under normal conditions) by the compression ratio (say 9.1 to make things easy) to the power of the ratio of specific heats of the working fluids (wether the car is running a methanol setup, or C16 race fuel or normal petrol). Air is about 1.41 so lets use this. So we have: Cylinder Pressure = (1bar) x (9^1.41) = 22.155bar which you can calculate yourself to about 300+psi. Obviously there are variables that effect this such as cam timing, boost pressure (which is what we are discussing here) etc. However if i remember correctly, most common cars run around a minimum of 11bar cylinder pressure. Obviously some cars will give much higher readings then this if running huge compression ratios and big boost and race fuel. So can you see that adding something like 5psi of boost is going to do sweet fark all on cylinder pressures, its the amount of energy that the cylinder can produce once the spark plug detonates the charge which drives the conrod back down that determines the amount of power it makes. If this energy is to great then something is going to let go. Ok im done, thanks for listening.

I'm pretty sure everyone on here is thinking the same thing about you dude. Read what everyone is telling you, no shit increasing boost increases horsepower (unless the turbo is out of its efficiency rating, then it is just making unnecessary heat and not making more power). However your argument started saying that you wouldnt run more than something like 15 or 16psi through a stock bottem end (cant remember the exact amount you said because i cant be bothered looking back). With your argument, what turbo are you talking about? I'm pretty sure your aware that a boost pressure on one turbo is completely different to a boost pressure on another turbo because a bigger turbo has more airflow, its airflow at a given pressure that makes more power (look at the example in the above post regarding a T88 and a stock turbo). So on something like a 2535 or a highflow turbo, pushing 19psi on a RB25, if its still in its efficiency rating, might make something like 240kw@wheels. Everyone knows aslong as the tune is good and you have supporting mods that this kind of power output on a stock RB25 bottom end is fine. Now on something like a GT3037 pushing 19psi will make closer to 320+kw@wheels, obviously this on a stock bottem end is dangerous and yes it will most likely let go. See whats different here, its not the bloody boost pressure that kills a bottem end, its the power output due to stress on the conrods, bearings, pistons etc. Your argument is pointless and you have no proof to backup anything you say, there are far to many variables. The point here everyone is making, is it is horsepower that kills an engine, not boost pressure!! And yes i can even predict what your going to say back to this "Increasing boost makes more horspower, you even said it yourself." So via your theory, putting a highflowing exhaust on a car makes more horsepower, you saying that highflowing exhausts kill engines? Running water-air intercoolers drops the intake temperature, thus creating more horsepower, you saying water-air intercoolers kill engines? Seriously man, what the hell don't you understand??

Lots of black smoke would indicate rings being f****d like mafia said. Dry oil is a bit scary though Drop the oil out and see how much comes out, if its barely anything id be looking at an engine rebuild if its chewed through all your oil in 3000kms. Do you have a wideband O2 sensor in the car? If not that air-fuel ratio gauge wont give much of a proper reading so yeah its going to pretty much just say its running rich all the time.

aka pineapples.

Probably the wrong place to post mate, most likely this will get moved to Cosmetic and Styling. The top one im pretty sure was custom made remembering back to the HPI mag.

My GTRS gets tuned next saturday with the microtech finally in and running. I have faith with my tuner and told him to keep winding boost into her until she gets out of the GTRS's efficiency rating. So if he says its fine on 20psi, im cool with keeping it on 20psi as long as the tune is good and doesnt knock. As i said earlier, its not a SR20 where you have to worry about valve float or rocker arms smashing off. The rb25 head (as far as im aware) in standard form is fine to take the pressure. Obviously the head gasket will suffer the most but i still believe it should be fine. Aslong as engine temps, no knock, and not driving the car like a maniac bouncing off limiter, i think it should be fine on those boost pressures. Ill let you know how the tune went next week.

Wow the gtrs went up in price from when i bought it last year, then again thats probably due to the exhange rate. Mine was $2300 delivered to my door from nengun. You wont get hit for tax from nengun, so your looking at about $2500 max. As said above, its not boost that kills bottom ends, its detonation, overall power output, heat etc, ie most RB25s start getting weak at 270rwkw+ but then again heaps have gone further on a good tune. Its not a SR20 where you have to worry about valve bounce, so pushing 18 or 19psi isn't something you should have to worry about, as long as the tune is good. Push 18-20psi through a GTRS or a 2835 and you will easily make your power output with supporting mods.

Yeah ive been wondering that aswell. Autosalon did a good review on the Hypertune one on their R33, said throttle response was a lot sharper and the dyno graph showed a power gain right throughout the rev range. Hmm...

BAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH!!!! Man i swear to god i nearly just pissed myself!

What do you want the car for? Daily driver/Drag car/Circuit car/Drift car? Are you on your P's, therefore cant drive a turbo model? What model are you talking about in each, GTS, GTS-4, GTS-T, GTR, CA18 S13, SR20 S13? Need some more information man, and besides, who cars what anyone on here thinks, go drive each one and decide what one you like and which one suits your tastes and needs.

Getting really angry and annoyed when trying to change spark plugs Just realised you were talking about the throttle body and not the plenum.......carry on.

Haha i was thinking the same thing

Chuck BKR6E NGK plugs into her (.8 gap) and it should fix it, if not look at your coil packs. Common skyline missfire problem.

So true. A mix of a TRD and bomex kit looks great on them. Love the TRD vented bonnets on them sooooo much.
