Rb20 Driving Like Shit.

[Beer Baron]

RB20 is 20 degrees. and forget looking at the sticker under the bonnet. they are made by halfwits. my GTR one says 15 (rubbish), my GTI-R one said 15 too (also rubbish). pretty much they just put 15 down for every nissan ever complied.

I have a GTR bonnet that has a very old factory looking sticker with RB20 stats... so I don't believe anything stuck to bonnets

Even if my base timing is low, timing has been fiddled with in the ecu so it is of no consequence.

alrighty ill have a look this weekend at the timing with my old man..

cheers for the help guys... much appreciated..

i had a play with timing today.. and advanced it as far forward as possible on the cas and it runs smooth and real snappy and plenty of power on and off boost.. with no pinging so far..

i will back the timing off a tad...

prob not to safe to run it at full advance??

car seems to be running fair normal... at idle the revs bounce around between 650 and 750ish rpm.. wonderinf if this oculd be due to not being tuned for the mods...

cheers for all your help guys

and one more thing..

what sort of gains have people had from ecu remaps...

i know they would iron out the power curves and that make em more reliable but what sort of gains can be expected?

cheeers yo

Re-maps are great. My complety stock 20 make 153rwkw on 9psi, after some tuning and setting the boost to 13psi it make 174.1 with a shit load more midrange

I reckon your cam belt is off one tooth on both cam wheels, A way to confirm this is to get a vacuum gauge it should read -19/-20 if you have stock cams, if its anything higher like -15/-16 start pulling off the front of the engine, cause it will need adjustment. The cas in no way should be "advanced as far forward as possible"... somthing is up.

Once you get it on properly you will even have more power and a stedy idle.

alright sweet.. insted of using vaccum gauge is it possible to use a boost gauge that has the vaccum reading on it.. and run it from the vaccum line for the fule presure regulator????

I have a rule - NEVER use the FPR vaccum line for anything what so ever. Its too mission critical.

Use something else, there are plenty of lines unther there.
