i know im bringing up the dead, but its better than making a new one.

is there any changes i should work with?

since im having ER34 N/A and i'm dropping off RB25DET NEO. what about the flywheel? pull push clutch, gearbox? turbo lines?

any more detail information could save my $$$ eventually.

cheers.

the whole undercar setup between N/A's and turbo's are difference. after picking out the differences, youll look at it and realise just how different the two models are...both look the part though :P

Tell me about it! Worse it seems if you own a Sedan ~_~ Unless of course if it's a GTV

R34 GT doesn't have HICAS (4 wheel steering) Traction Control (TCS) or Limited Slip Diff (LSD)

R34 GT does have an LSD as an option - Its on the original R34 Skyline brochure from Japan - RB25DE models only :P.

i read the manuals, it says the N/A one use R200V lsd type.

but how about the tie rod, castor rod, camber rod?

i know they have different rear suspension setup, does it means i have to look for a different rear swaybar and anti-rollbar as well?

well, at least im getting a r32 gtr brakes now.

cheers.

Sorry to revive an old thread, but i thought it was better to revive one then to create another identical one. Basically im looking for a way to check if my engine is originally from a turbo or non turbo R33. eg if the person just bolted on turbo bits or if they changed the whole engine. I know my skyline was originally (factory) non turbo as the badges are blue, open diff (until i got to it...) and no hicas.

I know the compression seems to be the only difference and thus i will do a compression test once i get my compression tester back from my brother..

Can you tell anything from the engine number??

Mine is: 181875A

cheers guys.

Is there little-to-no lag? aka pretty much instant boost? Badges doesn't mean everything, but blue badges are typically on N/As.

Are the wheels and brakes R33 GTSt items? 4 stud wheels and 2 pot front and 1 pot rear calipers were the go on GTS, whereas GTSt has 5 stud wheels and 4 and 2 pot calipers.

I'm not entirely sure from the engine number, I would assume that you can get some info from it.

Is there any Queensland mod plate to evidence any engine change?

Could even be that the owner put blue badges to fool other people in the know into thinking that it's an N/A.. but then like you said open diff and no hicas... Not many people do bolt-on conversions.

Do you have pics of the engine bay and other areas to try and discern whether it's a bolt-on, engine conversion, or just a bit strange?

my Na r34 has red GT badges :) they were there when i bought it tho.

And for the R34's, isnt it like ER34 for the GT's and something like HR34 for GTT's?

You could also check the coil packs??? different coils between turbo and non turbo

p.s

in New Zealand you can search the number plate and it gives you all the information about the car and what it was imported as etc etc

i think he wants to make sure that his engine hasn't been swapped, not if the car itself is orignally a turbo.

the easiest way to tell if it is a turbo motor that has had the turbo removed would be to put it on a dyno. if it makes over 100kw then it is a NA motor, LOL.

you could probably also look for blocked up oil and water lines. although i guess that you would be able to tell if it was originally a turbo motor just by driving it. if you test drove other NAs when you were buying yours then you would know straight away. a turbo converted to NA would be dramatically slower than a stock NA. if you get easily beaten by v6 commodores would be another indication, LOL

N-DAWG,

Yeh there is little or no lag coming onto boost, the wheels are the typical 5 stud r33 pattern. I know that the badges aren't everything though it was the complete absence of any sign of the hicas system which really set me off.

There are no modification plates on the chassis beyond the usual import plates. Thus im thinking that the conversion could have been completed before it was imported though Im really not sure. I'll grab some pics and post them up today.

R34- -,

I know about the coil packs, though they would be easy to switch them over.

What im looking at is seeing if the motor is a turbo or non turbo from factory. Reason for this is obviously about the compression ratio in the engine and my ability to boost it up. As it sits I can't see anything on the engine itself that points me in either direction...

Cheers guys

that will only tell you what sort of motor it was supposed to have (turbo or non turbo and what capacity). won't tell you the engine number to see if it has had a replacement engine put in that was the same type though.

Hate to tell you, but FAST won't tell you what vehicle an engine number came from: However i can certainly help out HERE

This is my data on the above.

I am releasing a website next month dedicated to RB's with a much more comprehensive list.

As for differences the heads are a different casting in R34 non turbo to turbo, have smaller ports and runners, which is to do with torque.

if your more interested, PM me and i have allot more information.

just so you know, if your website mentions RB standing for "race bred" i'm going to find the server it is located on and set it on fire.

      I neglected to respond to this previously. Get it up to 100 psi, and then you'll be OK.

      I agree with everything else, except (and I'm rethinking this as it wasn't setup how my brain first though) if the sensor is at the end of a hose which is how it has been recommended to isolate it from vibrations, then if that line had a small hole in, I could foresee potentially (not a fluid dynamic specialist) the ability for it to see a lower pressure at the sensor. But thinking through, said sensor was in the actual block, HOWEVER it was also the sensor itself that broke, so oil pressure may not have been fully reaching the sensor still. So I'm still in my same theory.   However, I 100% would be saying COOL THE OIL DOWN if it's at 125c. That would be an epic concern of mine.   Im now thinking as you did Brad that the knock detection is likely due to the bearings giving a bit more noise as pressure dropped away. Kinkstah, drop your oil, and get a sample of it (as you're draining it) and send it off for analysis.

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      By GTSBoy · Posted

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
