Exhaust Manifold To Turbo Gasket Exploded
Leeroy94 replied to Leeroy94's topic in Forced Induction Performance
I've purchased a multilayered steel gasket, permaseal I believe. I got a small metal ruler (closest straight edge object I could find) and the flange is slightly bowed in a concave shape. That being, the centre surface of the flange is further in than the surface of the studs. What can be done to fix this? And to further prevent this from happening. It's only bowed 0.5-1mm roughly. -
Walbro 255 is good. Another thing that is wise is upgrading your wiring.

Exhaust Manifold To Turbo Gasket Exploded
Leeroy94 replied to Leeroy94's topic in Forced Induction Performance
Turbo is only running 10psi.. Unsure of what type of highflow. It's steel wheeled and about 8mm larger in diameter. 220rwkw maxed out the stock injectors using a nistune. I've got a 3 inch bell mouth dump pipe going to twin 2 1/4 inch straight pipes. No mufflers or cats. Tabs are done up tightly. Warping definitely could be plausible. The gaskets blow out long ways inbetween the bolts, parallel to the rocker covers. -
Rb25det neo with high flow turbo making 220rwkw. Track car. Last two track nights I've blown two turbo gaskets. Had some crappy $7 composite gasket on when I bought the engine, so I replaced it with a factory metal one but that also blew out I double checked all the nuts and they were tight, aswell as having the clips on them to reduce movement. Turbo glows red.. I don't know if I need a special gasket to withstand the heat? I've tried searching the forums but couldn't find a clear answer. Which type of gasket is the best for track cars? It's just such a lengthy job to change it so I want to do it one more time but make sure it doesn't break this time. Cheers

If you think its a gasket, get a hose or piece of flexible pipe and put one end to your ear and with the other end scan the outsides of the manifolds. If there is a leak you will be able to hear it. Of course the car needs to be running to do this. Other basic things to check are: Fuel filter Fouled plugs (spluttering) - also check spark plug gap if you have feeler gauges Fuel pump - as mentioned Wouldn't hurt to do a compression test. Engine could just be tired in general. Without tuning, the rb20det engine torque curve starts decreasing at around 5500-5700rpm anyway. Unless you're in 1st or 2nd it doesn't really pull hard past those figures.

Rb20Det Loud Knock After Spark Plug Change
Leeroy94 replied to Leeroy94's topic in Forced Induction Performance
Yes the white part of the plug had snapped. I just replaced them all. I looked around but no one sold bcfr7es.. Only online but it would have taken too long to get to my house so I thought I'd go with the 6 rating plug instead. -
Rb20Det Loud Knock After Spark Plug Change
Leeroy94 replied to Leeroy94's topic in Forced Induction Performance
Yeah no bits fell in.. I checked. Would a stuck lifter cause the compression in cylinder 3 to jump all over the place though? -

I just did another compression test. Cylinder 3 is giving different results. Test 1 cylinder 3: 120psi Test 2 cylinder 3: 80psi Test 3 cylinder 3: 95psi I'm assuming either what badgaz said, a stuck lifter or, a broken valve spring. Valve spring would explain the knocking, missing and broad variance in compression results.
