Hi Guys

What do you guys recommend for a A/T 2003 V35 coupe. An ECU or a Transgo A/T Shift Performance Kit?

I have been told the ECU will cost about $800-$900 fitted and the Transgo Shift Kit will cost $300 (not including labour cost).

So performance wise is there a very noticable difference?

Regards

Manny

An ECU really won't do much unless you have serious mods that benefit from 'tuning' the ECU.

FYI the shift kit will cost $500+ to fit (incl. service and oil) by a shop - I hope you have included that in your equation.

Uprev gives you control over the gearbox to some extent.... But if you are to supercharge or turbo charge at a later stage you will still need a shift kit done.

$500 not including oil is a good price IMO.....just make sure you go to a workshop that has done a couple and knows what there doing....I've seen a heard a couple of horror stories of can do workshops that can't do! And don't let them use dextron for the oil...it will stuff the gearbox.

Yes it does.

So to some extent you could actually replicate what the transgo shift kit is doing Physically, but tuning the ECU to do it electronically. I have done it to my car, however I also have the transgo shift kit. So I am unsure how good you could actually replicate the results of the shift kit in tuning the line pressures the ecu tells the gearbox ecu to run.

However you also get the benifit of the tune. I don't know what the rwkw difference will be once you tune on a stock car, but you will get some benifit as well as losing the speed limiter, and setting the rev limiter to your desired limit. You may also chose to run upto 5 different ECU maps.

What ecu have you been directed too? If its a piggyback, then run far far away. Chances are the person who is giving you advice has NFI about these cars. Uprev tuner is 700USD. Dyno tuning is on top of that- and I would charge more than 100-200 to do the job.

^^^ Nope that price is not including the shift kit .... but remember a business workshop has significant thousands of dollars per week, every week, to pay for. Plus warranty if they stuff something up. In Adelaide we pay around $120 per hour for labour alone.

Are those prices including the shift kit? Otherwise I need to put my prices up. lol.

I was thinking that to Scott.....if that's the price not including the kit then your getting ripped IMO.

$500 fully fitted including the kit....not the oil. If your in Vic can't act Scott....NSW me.....other states :( ....ATM!

Uprev ftw if you know what your doing with tuning.

What oil are people using when having the kit fitted? I gave the local gearbox shop close to my work which a couple mates who have had commo boxes rebuilt recommend a call. They can supply the shift kit for $460 as opposed to the $300 ish via ebay etc

The guy I spoke to said he had rebuilt a couple of boxes out of pathfinders which are the same RE5R05A box the 350z/V35 have. When I asked what oil he used he replied that he uses a synthetic oil he gets in bulk from Singapore which would cost me $7.5 per L and has had no issues with the RE5R05A boxes he has used it on..... This is a shop which has been around for 10+ years so id hope he is right :/

Mine was running generic Dextron III, although it has extra clutches installed in the baskets. I don't recommend it for a stock RE5.

I use the Nulon synthetic usually as it's proven and easy to find.

I bought a shift kit off ebays for like $250-$300 i think it was at the time and had a full service on the box and kit fitter for $200 from my local auto transmission shop, they used the genuine matic J fluid also from Nissan the guy had a half full bottle of it as a door stop to keep his office door open

That's a win and a good price IMO!

      Mistakes were made, my R34 Story

      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.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      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.
