I just had a POD installed on my 1996 GTS25T and now when i hit boost at about 4000-4500rpm it feels like you just slammed on the brakes then let them off and slammed ur foot on the accelerater. Its really violent. Is it possible that they have broken my afm because it didnt do this before they installed it? what other causes could there be. I have tried resetting my ecu but that didnt help.

only other mod is a 3" cat back.

Thanks.

the 4000-4500rpm is when the boost solenoid opens and goes to 7psi, from 5psi

not sure why you'd get the slamming feeling? Maybe take the pod off and check your AFM for damage? Or try a friends 33 afm and see that goes, maybe swap pod and afrm from another 33

sounds right jay! once the pod goes on and removes alot of restriction it will let the turbo spin easier! happened to me when my pod broke open! started pushing 16PSI in and boost cut came on hard, similar things to what you've described bobby^ turn the boost down!

man if I had $1 for everytime this "cut at 4000-5000rpm" question I answered, I'd be rich..

with your new induction and free flowing exhaust, you are getting a higher boost.

therefore, you get a miss.

fix = take out your spark plugs, re-gap them to 0.8mm and put them back in and go for a thrash.. you'll see redline without a hitch.

The reason you only get the flat spot from 4500 to 5000 is because you computer adds more fuel at this point to allow for the extra boost that your factory boost soliniod is adding. This flooding effect may now have been multiplied buy that fact that your air filter is flowing better. 4500-5000 is also the point in which the variable cam shaft kicks in which from my understanding will also allow a greater flow.

This prob is also caused by the ecu rev limiting but not the case for you if you have the stock boost controller. Ps, since you where mssing with the pod and stuff check to make sure that the hoses to the boost solinoid are on tight, if not then you are bleeding more boost then stock.

After changing the gaps in the plugs, make sure you re-set the ecu again as every time you are experiencing this flat spot your ecu could be retarding your timing which equals loss of power.

my 2 cents, hope this helps as I can remember how pi**ed off I got when I had ignition probs...

Hey ive got no pod on my 33, but ive got a front mount and full exhaust (stock boost), when i hit about 6800 or there abouts, it feels like it has hit the injector cut out, could this be a similar problem? maybe i should gap the plugs down aswell?

i have no boost control of any kind, factory gauge says 3.5psi :S

Hey there,

The factory gauge in the R33 doesn't read in PSI. I'm not sure what form it measures in as I don't have a Skyline. Possibly microbar or dyne/centimeter2??

The problem with my car was that mag and turbo had given me a shit pod filter. After spending 1.30hours in st hitech in new market, having changed the sparkplugs and ****ed around for ages they installed a apexi pod instead of the shit one that mag and turbo had put in, it was only 30$ more. The whole exercise cost me 420 including pod and sparkplugs (my old spark plugs were crap). Costly to say the least.

What we can learn:

-Mag and turbo are useless

-St Hitech kick ass

-Apexi duel funnel > all

at least mag and turbo gave me my money back after much persuasion.

how about adding to the "What we can learn" list..

should have bought a $90 K&N panel filter to replace factory filter and have NO problems and better gain than what you have now.

      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.

      Jacks that fit under GTR lips that can reach the subframe?

      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.
