hey everyone.

R32 GTST 1990

Was driving home last night with the usual semi-enthusiastic driving we all like to do. Turned a corner and the car just didnt feel the same acceleration wise. Also going up hills in say 3rd or 4th it will rev to say 2K or 3K and just sorta not want to go past this. Out of first and second it will rev out ok but a lil bit slower then usual.

The stock turbo gauge indicates that it can get full pressure...so i dun think it's turbo

the car also sounds exactly how it should (perfect note) at idle.

such a wierd thing...i turn the corner and power is now only 2/3 of what it should be and up hills can only make it to a certain limit.

I have done my searches and most people seem to report power losses ABOVE a certain higher range (say 5K) mine seems to be just in general not that great a much power as before

I'm thinkin fuel pmup, or piping, or coil packs as per the suggestions in other threads

just wanna know if anyone experienced this problem and what was the resolution??

any help would be great!

fair enough guess i must admit...but....the clutch was put in like a yr n half ago so not likely.

i think it actually MAY have been bad bit of fuel and or sparkies gettin old...cos it was ok to drive today...very odd tho

hey i seem 2 have a problem similiar 2 yours

in second or third wen i flat foot it the car seems 2 jerk at times. feels like its struggling.

must add that it doesnt happen all the time.

its standard apart from cat back exhaust, pod and bov. Car seems fine otherwise.

Had feed back, and there suggesting it could be either:

-fuel pump

-engine coils

spark plugs

Hope that helps :)

hey mate

yeh i thought it could be one of those

there's no real problem at the moment hence i reckon its bad fuel or sparkies lil bit old

with ur car jerking i'd say could be fuel pump.

my mate recently changed his fuel pump in a 200sx and said it was jerking before he changed it.

Just a lil bit of feed back...i dont want to tell u to change anything cos i'm obv not the mechanic.

cheers

    • Just get rid of the orignal low impedance injectors, replace with modern high impedance injectors, and you won't need the resistors. Wire direct, as per any other engine.
    • Tao, we're not talking about the ECU boost ref. We're talking about the wastegate signal source.
    • Flapping up and down is a consequence of the varying pull on the belt. When the engine speed is suddenly increased, the tension in the belt increases too. When that engine accel changes to decel, the tension is reduced and turns up as a little extra length of beltes between the pulling and dragging pulleys. That extra length flaps up, then down. There's all sorts of other harmonic stuff going on too.
    • hello ladies and gentlemen so i’ve swapped a rb26dett into my r33 gtst and ive come across many speed bumps but its nearly over what im having issues with is the injector resistor box that are normally on the RB26 fuse box but im still using my rb25 fuse box and as a result my injectors aren’t getting power and is the last thing i need to figure out so the car can start. can anyone help me out on where i can find a wiring diagram for the rb26 harness to see where the injectors are supposed to receive power 
    • The boost pressure at the compressor cover will be higher than at inlet manifold. lets say, trying to hold 20 psi flat at 7000 RPM. If your wastegate opens at 20 psi measured at the compressor cover, the engine may only be seeing 16 psi. Your base pressure reading at engine would be 20psi by 4K and 16psi by 7K while your MAP at compressor housing still reads 20psi at 7K. For this reason your ECU's MAP source is never on the compressor cover. This difference isn't a major concern if you're using an electronic boost controller (EBC).
