Finally got it all together and did first dyno session putting down some decent numbers.. I do have to go back and retune again as brand new power FC boost controller did not work again so we ended up running it on manual boost controller. I will be getting an electronic one so i'll re-tune again and likely play with cams/gears--currently set at zero. My main question is, what are some general boost levels that many of you run on your cars? I plan on running this motor regularly at 22-25psi.. car will only be used for couple of monthly coffee meets and occasional evening night rider passes.. along with few drift events each year.

Any feedback is greatly appreciated!

Set up is as follows in S13 chassis

Mildly built R33 (pistons, rods, upgraded oil pump, HG, head studs, tomei poncams type B

1000cc injectors running power FC d-jetro

e85 race gas

all the misc bolt-on's you can think off

running GTX3582R, .82 rear

Here is what it made at 22psi..

Thanks for the info gents!! I wanted to make sure that 22-25 is not excessive.. we can def run higher boost.. just decided to end it at 22psi as we were already sitting on the dyno for 4hrs setting up from scratch.. i guess we will have to hit 2 bar next time around! Max out that profec A, lol!

I honestly have no idea!! We've triple checked that everything is connected as per manual and still nothing.. i bought it brand new last year along with new LED commander.. i did read that many people had problems with getting it to work.. overall PFC is just prehistoric in my honest opinion.. works OK, but i will probably switch out to different standalone later this year...

first time i went to dyno last year i had 1.02 rear housing which was just too big.. and soft springs in the 50mm gates so the car only made 10psi and it took forever to build 10lbs.. this time around i swapped stiffer springs in the gates and thought that PFC boost kit is now all working properly.. when we got there it wasn't.. however springs were good to make 17lbs.. so the we opted to connect manual boost controller hence how we got to 22psi and stopped there..

I'll be throwing on a good 'ol Greddy Profec A which i never had a problem with and do another session once the car is out of paint..

At this point I'm just happy to making some power! As the car had been sitting idle in garage for years being worked on as time permitted.

Pretty impressive numbers. Just keep increasing the boost until it becomes counter productive - wouldn't have thought there was much more in it but interesting to see.

I would recommend a Link ECU with a Mac Valve to control boost. Pretty laggy - I presume this is for track or drag racing?

I'm pretty sure it will hit close to 700 if not more at 26psi.. We will see once the new boost controller is in and dynoed again.. I also ran that filter condom which I hear robbed easy 10-15hp..

Overall I really can't even use the amount of power it's currently putting out let alone adding more, but good to know that it can..

Driveability I was never looking for fool boost at at 3K, car is mainly used for drifting and fun on the street so this band should work ok with some massive rubber.. It's running a brand new rb25 box and we will be putting a 4.6 final drive ring and pinion to make it even more fun :) I'll report back once she's all together

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      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.

      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!

      Mistakes were made, my R34 Story

      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.
