we overlayed our circuit cars dyno chart with both power and torque against the GT-RS's on the drag car and you would swear it was the same car.

The low mounts at 22psi and the T04Z at 24psi...same power but the low-mounts power was made a little earlier and held on for longer...same with the torque...both are HKS powered cars but the circuit car was on Sunoco and the drag car was on BP98.

Wow interesting! What comparative engine spec? I'm not a fan of the T04Z and I am a fan of GT-RSs so I guess in my head its two better matched turbos against a dinosaur with a nice core. Any chance of sharing the overlay? It would help a LOT of people considering the options.

I wish there were more GT40-based setups on RBs to compare with.

There is more to this story though....the T04z was tuned to make every single KW...13.0:1 at 24deg GT-RS's were using a run in tune... 11.5:1 at 18deg.

Engines using STD cranks...87mm forged pistons...similar head porting and camshaft profiles (circuit 280deg drag 288deg)...both z32 power fc cars using blitz boost controllers.

Thats pretty interesting, with my main purpose using mine as a daily driver i want to be able to give mine a stab and not have to wait til the next set of lights before i hit boost....

thats why i'd be leaning towards 2.6 + GT3540 or RB30 + T04Z

i don't mind the -7's but they won't deliver the top end power that i know i will want in the future

i dont want to open up old wounds, legit question this.

the built bottom end from NZ costing was it $1200 cheaper then the one from Aus?

Anyway, question is, whats the shipping fees involved or do you have a warehouse over here?

Ive seen over seas shipping for software, it isnt cheap, i cant even imagine the price for a motor...

Also my other question is, if you guys can produce a turn key motor that runs 9s for 19k or whatever... how come it cost some guys 100k for their machines? i may be missing something here, but if someone could PM me the reasons or differences that would be appreciated.

Thanks,

100k - there is more to a "Machine" than the motor mate and some people also add how many times they have broken things / changed things to get there final $$$ figure

My motor was $450nzd shipping in a crate from RIPS in Rotorua - Melbourne Australia

cause i build my own and have my own machine shop...$19000 is just parts! But to be fair to Robbie...that was when $1 bought 100Yen. Same build would now be very expensive...if you care to look back a page or two i actually admitted i was wrong...which is a bit of a rarity on here for people to do even when they know they are wrong. When you look at it in today's money $19000NZD is about right.

Also it takes more than 1 build to develop a car to sub 10 times...im on my 3rd engine now to shoot for 8's, my 3rd turbo set-up, my 3rd different type of gearbox, my 4th type of clutch, my 2nd type of diff...shall i stop now?

You dont just tick all the boxes in the parts catalogue, bang it all together and go and run the numbers...it just doesn't happen that easy...i wish it did.

Not only did Mr Dirt admit he was wrong he also eluded the possibility of crossing to the darkside and playing with a dirty 30 :)

i said increased capacity...i dont see anywhere where i mentioned robbing the trusty forklift of its power.

im building a 30 though...its gonna be big...its going in a VT Commodore wagon.

That could be why his nut sac is hurtin. They're growin.

nice one silver fox...ill pay that for sure

honestly i don't really find it financially justifiable to only increase displacement by 1 or 200cc it may make a difference however i have come to the conclusion that if i do stroke my 26 it will get some form of a R I P S RB30

interesting. I did look through the pages, and that is what i thought, that it would take a few builds to get the car running 8,9,10s etc. Just wanted check.

clear my mind a little :sick:

Should also say, gratz with the power. are you after track and drag times or just dyno power?

Thanks,

RIPS current shipping by sea rate is nzd600 which is still pretty good I feel except that any engines ordered this month or next get free shipping so its even better :-)

There's alot in building a quick car and the motor is just a part of it, we do have some very well proven combinations now where 10s, 9s, or even 8s with a very streetable motor is actually quite possible where the other areas of the car has been done correctly.

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
