Hey guys, when I give my car some beans at about 5k it starts popping and almost hits a bit of a wall, as if it struggles to rev more. What could be doing this? It's a rb25det with a exhaust, that's it.

Lack of fuel?

has it only just started? perhaps thats the peak of your power curve

Detonation

 

Start by checking the timing and ignition system

My car did that and found faulty leads, get someone to take it for a drive who knows what it kind of problem it sounds like i.e its not getting spark or not enough fuel, ect.

Wrap the coils up in electrical tape and then try it.

I'm with trev. Is it fouling plugs at all ? Shit coils will fuel foul the plugs.

i had the same problem on my skyline. the plugs weren't gaped properly. gap them to .7 and that should fix it. if it doesn't your coils have had it but try the plugs first as even second had coils are 70 each. hope this helps

That fastest way to fix it is to stop letting clowns pillage your snickers factory. Period.

 

If that doesn't work get the clown back or try buying a toyota.

I only just bought the Bloody thing, and I'm shit with cars :(

It could be some type of limiter...

What year, make and model of car is it and any other information on the engine.

It's a series2 stagea neo25 has a pod and exhaust, that's it.

I'm not sure if it has been tuned because the last owner is in japan :(

Best thing to do would be get it tuned... a good tuner will do a diagnostic test and dyno it. You'll get answers.

I was thinking it may need one but I don't have the coin

Check the f@$king coil packs, why lay out coin for them to probably tell you it is the same thing, sorry but I don't know why people buy cars that they don't research on, splitfire coils for a NEO can be had for under $750, if it is the coils then drive it nicely until you can buy some.
