I accidentally bought this for my car and I needed a 6 bolt. Never used but taken out of packaging. Comes with grenade pin.$90 shipped

Whats up guys. Here's my issue. I keep seeing knock, even in 2nd gear, around mid range. Boost is set to only 15 psi and I see that my AFRs drop from 11:1 to 10:7 around 4.5k rpms, then it goes back to 11:0. Not sure if this is whats causing me to run a little richer here but that might be...

Hmm... Not sure about timing is lost and supposed to be added back.Check for loose bolts around knock sensor, check and make sure the knock sensor is tight and there is no ooze coming out of the back of it, as that is a dead give away at a bad knock sensor.Have you done a boost leak test...

What are you using to monitor knock & tune? The rest of your mods? It could very well be phantom knock

Block off your PVC. Even brand new ones from the dealership leak in my own experience over like 8 psi and it can cause headaches when doing a boost leak test. With the PCV leaking air into the valve cover, it basically is leaking air into the crank case.How many miles does the motor have? An...

Just curious, how is the parts store oring holding up? I was curious if there is any difference in oem vs autoparts (resistance to fuel)

I believe if youre just going to run spring pressure then you don't have to have a boost controller and you can leave the top one vented. if you're going to run more than spring pressure then you need the mbc connected to the top

Head gasket is going to be a decent amount of work. You might was well replace the timing belt when you do that if its 90k on the original. Do those before throwing on the turbo. If you don't want to upgrade the injectors later you might as well get some that can handle e85 for that turbo. I...

I'm going to chime in too and say the 1.5 quart of oil loss is concerning. Especially since it was related to an overheating issue. If the car was overheating for too long you may have warped the head or blown the head gasket. Any mixing of oil and coolant?

Does the car have aftermarket cams? 145 is a bit low for compression unless you have aftermarket/larger cams. Not spooling till 6500 or so could indicate a large exhaust leak before the turbo. Also you should hook up your wideband to ecmlink so you can log that. That is crucial for knowing when...

UV dye helped me a ton. We are literally just spit balling until you show some pictures.

If you are going to rebuild the t-25 look into rebuilding it into a t-28. Depending on what your goals are.

+1 for anti seize. It only takes you one time of removing them to learn that.

I'm not sure that the NA oil filter housing would be considered an upgrade here.You can watch Jafros videos on youtube. You can "port" the oil gallery on the block. It's much less of a porting job as it is sanding away the rough surface of the galleries to a more smooth finish.If you have...

You're gonna wanna port the flapper on the 16G to avoid boost creeping into higher boost that your fuel system can't handle.
