Hi all,

Once again i've come to you in need of some help. My car ('93 R33 gtst) has recently started playing up, in the last month or so what's been happening is under load, full boost and high rpm, the engine light has been flashing. I've done alot of reading up on this and found that it is serious and requires attention. So this is me attending to it :)

The mods on my car are as follows,

Power FC

Splitfire Blue jackets

Boost T Currently running 12psi

Highflowed turbo (OP6-hypergear ~480hp?)

Greddy Front mount

Bosch 040

Custom 3" straight pipe all the way through

Standard injectors

Standard afm

What happens is when the car is warm (water temp ~82-84c) and I open throttle in either 1st or 3rd, from about 5000rpm the engine light will give me about 4 or 5 consecutive flashes. On the pfc display I get a peak knock reading of anywhere between 85 and 130. I don't have a wideband so i dont know what my afr is but I'm quite certain its leaning out badly. The guy i bought the car from said that it was tuned to 15psi (which i now think is bullshite) so running it at 12 psi shouldn't be causing it to knock so much.

I'm in the process of getting a z32 and nismo 740's

What i need to know is should I go ahead and keep driving it? Should I get it retuned? Should I wait until i have the afm and injectors then get it tuned? Just some advice would be nice as a mate of mine just blew his engine which had similar issues previously.

Sorry for the long post... Any help is much appreciated

Cheers

Nev

keep driving it with those knock levels and you'll find yourself walking home.. i was told anything over 60 is getting dangerous... so dont drive it that hard til you have tune, your probably running out of fuel with the hypergear turbo.

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
