Hey, im having an issue with my rb20det before 4k revs it felt very boggy and then after 4k revs it felt fine till 6k then it felt like it had no power

it has a 25det gearbox and a r34 neo turbo fmic 3inch exhuast

 

ive tried to turn boost up and down didnt do anything ive also tried resetting timing and the timing was off but now its set but its become worse where if it gets any boost at all if just boggs down

 

have no idea what this could be or what to even look up any help is appreciated

Could be a boost leak or it might be pulling timing. Have you checked for fault codes?

havent checked for fault codes as dont have the right reader for r32 dont think its a boost leak as boost doesnt fall off or anything

R32 ECU diagnostic can be triggered with a screwdriver or a paper clip. Read all about it.

It will be a boost leak, or a dying fuel pump as #1 suspects.

After that, it is absolutely everything else in the engine bay. all the usual suspects. read all about it.

yeah i suspect fuel pump or the regulator, i was told to block off the regulator return and see if problem still happens

No. Put a fuel pressure gauge on it and drive it under load. This is proper diagnosis, not half-baled diagnosis. If the pressure doesn't do what it is supposed to do, then you blame the pump. Your reg is very unlikely to be crook.

alright ill try do that, i just did a ecu diagnostics and got code 34 which is knock sensor

Bypass knock sensor with (500k resistor - I think. Look it up, it's findable). If the knock sensor is crook and it's running on the knock map, it will feel doughy. This should make it feel better. Then you  just buy a new one.

I just had a look and I actually have no knock sensor loom at all, both knock sensors are there just no loom, going to borrow a friends and see if that fixes my issues. Have never had a check engine light tho but its always had this issue since I owned the car so its never had knock sensor loom.

    • 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.
