Hey guyz

Finally got my 32 on the road and have noticed that in sum gears it seems to lag.

Now im not to sure whether becoz it was sitting in japan for 5mnths without being driven and when it arrived it had no fuel at all so possible sum shit is blocking the injectors but yeh not running the best

The engine is a stock rb20.. no other visible modifications.

Not sure wat psi its running either..

When you punch 1st and 2nd gear the car seems to respond particularly well.. however when your just crawling and then put ur foot on the gas say when ur in 2nd there is a short wait b4 the car decides to move, same with 3rd gear too

Seems to me like its missing...

Um any suggestions?

Thanks Joe!

They don't have much low down torque you need to keep it up in the rev range a bit, between shift changes do you:

* Clutch in, change gear, clutch out, THEN get on the gas,

OR

* Clutch in, change gear, get on the gas and clutch out as the revs are rising?

You need to be doing the latter, after having driven a V6 auto commo for the 3 years prior to getting my skyline it took me a little while to get out of habit of just putting the foot down and expecting something to happen, I'd just put it in to gear then put the foot down and it reacted very sluggishly just as you're describing. But maybe that was just me. :D

Also try the computer reset trick, first go grab a tank full of BP Ultimate (any 98RON will do but i like BP) and take your car home, disconnect the negative from the battery, hold the brake pedal down for a min, then reconnect the battery and take her for a thrash.

This all puts the ECU back in to self learn mode making slight adjustments to ignition.

If you eliminate you shift habits, fuel quality, ECU reset as possible causes the next step is to check the timing.

i think they are laggy, but not as bad as everyone makes out.....with an exhaust, cam gears and hi flow panel filter it made a world of difference......on and off boost, your not gonna take on a rb25 or rb30 and beat it down low but they go well for that they are.

my 2cents

Now think how fun it would be on the street with a decent turbo trying to make over 200rwkw. :(

You do get used to it and adjust your driving style. :D

Yogi is right.. The ol' RB20DET does go really well with a few mods for what they are. I was impressed with how well mine was.

Once on boost they rev nicely and do go well. Launching is another story. Mine would bog down with anything under 4000-4200rpm on board.

mine was a bit like that too and I had, filter,full 3" exhaust, FMIC,1.0Bar boost etc...

I think its just the engines nature man

take it out to the track for the day and have a chance to run around without breaking the law and get used to the car would be my advice. I did everytime I added some mods and it helped

Throw the exhaust and cat in the bin, get a new system, get a Hybrid FMIC, and throw in a new fuel pump. Combined with a good service with fresh fluids and your pocket will be $2,000 lighter...

The difference will be huge. You will have about 150-160rwkws and a in that state the engine can be flogged repeatedly for years and another 50-80,000kms:)

I wouldnt really bother with a boost controller as you will find you will make around 12-13psi anyway with the breathing mods.

Yeh they can be a little breathless, but ppl, they are a 1400kg 2.0L turbo car. I love ringing the RB20s neck, it feels sporty:) Half the fun of turbo cars is the rush onto boost.:)

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
