R33 Gtst

[Mattw_83]

ive suspected engine pinging of late. Although its seems intermittent. Sometimes its seems to to struggle under full load 12psi. Symptoms arently exactly an obvious engine miss or stutter. There is definate ping/rattle lower in the revs, intermittently. This was treated during on road tune by retarding timing lower in revs (2900 - 3200)....

Going to replace fuel pump ASAP. Ive had conflicting afr readouts from 2 dynos and a wideband on the street. Usually sits around 11.7 (its tuned for this) but has moved into the very lean on a couple of 2 gear full load street runs. Then back to normal on the third run.. frustrating.

Its really beginning to bug me as im forced to putter the f**king car around in fear its gonna blow... im unfortunately considering getting rid of it. A shame because its in top condition and i enjoy driving it.

Is there something really obvious im missing and should replace whilst i do the fuel pump? ive been in a r33 will failing coil packs it doesnt seems to be similar to that at all. Ill be doing the remap again straight after so id like to attempt to rectify this. 200 ATW is all im after id just prefer some reliability...

stick a fuel pressure gauge on it and check for pressure bleed off..

it may be solved with a swirl pot and another pump.

200wk, you won't need a swirl pot, but get your fuel pressure tested.......takes about 10minutes max.
