My Rb26 Sounds Like A Wrx

[toy515]

hey guys

i have a rb26 in my s15 its been recently rebuilt, i was driving it for a week or 2 and it now sounds like a wrx

i was running bcpr6es gaped to .8 i took them out cleaned them put them back in and it was fine then took it for a drive and it started to do it again so i bought new plugs the bcpr7es gaped to .8 and its still doing it i done a compression test and its roughly 140 in all what could it be? exhuast leak? head gasket? i have no idea

cheers

Possibly inlet manifold gasket leak? I had this issue about 6 months ago, replaced the gaskets and problem was solved.

Hope this helps!

could be faulty coilpack

+1 for coilpacks.

Same thing happened with my gtst - it was sounding like a wrx and down on power - replaced coilpacks and the car ran better than ever.

and i bet it only goes as good as a wrx now to it will be a coil pack mine did the same thing

Does it do it on full load aswell as light load???

to diagnose it if it is a coilpack problem, while the car is running like a wrx... unplug each coilpack one at a time... if it gets worse, when its unplugged that coil pack is fine.. if it makes no difference if the coilpack is plugging in or unplugged, try swapping that coilpack with another one from another cylinder...

if the problem moves with the coilpack, u can bet its faulty.

i changed plugs to and played with the coil packs to.... it would run as normal when cold....

till the coil pack would warm up then it would play up again would take a few mins as well befor it would do it, then it would start again.....

if you have the coin go and buy some spitfires
