Intro & Help Request Re. Fuel

[Sol32]

Hello all,

I'll start with a little intro, my names Andrew from SE Melbourne, and last week i became the proud owner of an R32 GTR. I'm over the moon with it (I upgraded from a tx3 turbo) so far, except for one little drama, which I hope someone can help me with.

Now - this topic I'm sure has been covered ALOT in search, but after sorting through the posts I can't really find a definitive answer. Here goes:

-The car has been in storage for months on end since arriving in Aus in April. Who KNOWS how long in Japan it was left undriven for. The compression tests / leakdown tests were all fine, ~165psi throughout. Now my point is, the car had fuel in its tank all this time. The bloke I bought the car off told me all of this, and told me there was a yucky mix of stuff in there. The engineers had in fact drained the tank during compliance (left a little in there), but I'm guessing the fuel lines still had the bad stuff.

NOW -I bought the car, and drove it for 2 days, basically blowing my load every time I gave it some. I then put in a tank of OPTIMAX (yes, I know, /slapself - BP ultimate from now on) and since then, its been hesitating, stuttering, cutting out, stalling etc. after any sort of boost is reached.

Anyone have any ideas what this could be? Dregs in the tank getting stirred up by the new fuel and pumped in? The dude DID tell me to change the fuel filter, and that's getting done in the shop today. If that doesnt fix it, can anyone suggest anything else?

Thanks in advance

Andrew

Take it to a good workshop and get them to look over it is the best bet for a car you arent really familiar with

And to cover the "workshop" question, look into the "Vic" section of this forum. There is a sticky with all the info in it

Good workshop check for sure, and the fuel filter is the first thing I was going to suggest

Good luck with it

then injector clean, all the little cages on top of the injector maybe full of crap.

Thanks for the help fellas, find out tomorrow if the fuel filter is the end of my woes.

Cheers

Optimax is fine that is not the problem. Any of the recognised 98 octanes are fine.

Fuel filters are cheap - I'd replace that and run some injector cleaner.

A friends R33 witht the petrol from japan cut out at 5000rpm. I think the importer after that mixed a lot of methylated spirits in with the fuel (double check this) and just drove it softly for a while.

Workshop might be the best - if you are leaning out due to injectors being clogged could blow the engine
