i have a 4 door aussie 31 with a series 2 rb25 in it, ie self igniting coils, and pink lablled afm.

been on road a long time, but ive just got it a month odd ago.

did cooler and zorst a week and half ago. garret cooler, and 3 inch turbo back system

since then, whenever its on hard load, mainly on a cool night, it will begin to pop and stutter around the 5000rpm mark, and keep popping as long as foot is down, bring it onto boost slowly and not full load and its ok

plugs are 7 range ngk's, 100km old now, gapped to .6

it will barely do it during the day , when it is warmer.

fuel pump is a 500hp walbro and its rich, the flames and black rear bar are testemant to that as well as the alluring aroma of fuel that follows car around.

possibilites

coil

afm

boost cut

any more?

Hey, mine does something sililar, aussie 31 series 2 rb25 fmic all else stock, when nailing it in the dry it will run ok half the time and piss and fart the other half, but in the wet as it starts to spin in 1st or 2nd and the revs climb too quickly it just starts to rev then completely dies in the arse, then thinks about it, revs back up then dies again... veeeeerrrryyyy frustrating.

Tomj i feel your pain ;)

yeah thats what i meant, if you hit the limiter too quickly, which happens when spinning the wheels, then it just shits itself. but if you acclerate full throttle without spinng it doesnt cut out but surges randomly thru the rev range. why oh why.

boost cut tom you need an ecu or fuel cut defender

 

and dont be a cheap skate wind the boost back to stock till you if a boost gauge

 

 

 

seriously a  cheap boost gauge cost me a motor so imagine what no boost gauge could do

meggala

yeah ill do that, see what boost its making

whats stock boost cut on a 33 auto ecu?

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • 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.
