R32 laggin probs..

[cattivo_69]

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.

yeah, the rb20 sucks down low... they only start to make some power at 4000rpm, and then sing at 6000rpm+

[pnblight]

It may need a good tune to aussie fuel and conditions as almost all stock imports run very rich and benefit from a good tune and the guys are right the rb20 isnt the best down low

[Oosh]

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.

yup.. rb20's are lag lag city.. I think that is probably just what is happening there

foot down.. dum dum dum.. oh here we go some power (finally).

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.

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

thanks guyz for ya help..

im goin to give it a good tune and put say a good k&n panel filter in, see how that goes...

Any other tips for the r32 gts4?

thanks again

Joe!

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.

Mod the wastegate actuator bracket as I did.

Holds 1bar of boost easily right up until the 7500rpm cut.
