sounds a bit like how mine wasa

my car used to feel sluggish at full throtle but at 1/2 or 3/4 it felt fine.

it could be running very rich and also if u havent yet gap ur plugs to .08 it cleared

all my flat spots.

hope it helps...

how do you expect fire to come from the engine if it has a cat in it?

a cat is like a sponge made of a hard clay... aint no fire getting through that...

i sugest you but a plumb back bov on there, check your intercooler connections for leaks in the line, and put a cat in your exhaust...

Chances are your coilpacks are shagged, when i got my 33 they were stuffed and flooring it through tunnels sounded like a machine gun, i had the exact same problems though, loss of power, shotgun bangs etc, tape up your coilpacks as per the DIY in the tutorials section or do it properly and buy splitfires. Changing the plug gap will only mask the problem.

Won't be the coils. Try replacing the atmo BOV with your stock BOV if you still have it. If that doesn't work it could be any number of things but it's only going to be fuel related as you need lot's of fuel for flames to make it past the cat and mufflers. Could be any of these+more: faulty afm, leaking core, piping or hoses, fuel regs crapped it's self, could have reached r&r...

I've seen flame go through a cat.

Mine did it once.

Do it too much and the cat WILL collapse/burn out.

Most likely, you've got an air leak somewhere, and under boost you're letting air escape (Meaning rich AFR)

This will be AFTER the turbo, before throttle body most likely.

so starting from cheap things to check to expensive i should. check cooler pipes. check spark plugs and gaps?

what else

      Stock rb25det neo questions

      By GTSBoy · Posted

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!
