Turbo BS Thread

So I should be pretty good with the factory gap then?

 

Not going to work with my engine of choice, would be easier

Woah thatsalota dough

 

Yea but that's everything to hook the trans to the engine, clutch included. If I knew how the clutch was setup or took the time to piece a clutch together I think summit racing sells an adapter for like $500

 

Pull them out, inspect them, check their gap. Look at the coloration of the plug and reference that to a plug fouling guide on the interwebs. Report back, and verify your gap, please.

Do you habe the Torque app for your phone? You can get a bluetooth obd2 communicator, and connect up to your phone. Will allow you to check codes, and view short term and long term fuel trims. The most important diagnostocs tools we have to determine whats wrong.

 

What makes you think, that if it bolts up to one R series transmission, it wont bolt up to another?

Bellhousing pattern is identical.

 

Ah, gotcha. Hadn't found that out yet.

Need one for a transfer case as well though

 

Here's the original sensor next to the new one

 

Did that one end up working out?

 

I'm just about to try it just about to do a test drive

 

I pulled my plugs and regaped them .041 to .028 but I also changed the o2 sensor so I don't know what deference the regaping made. In this video in 2nd gear between 4000 and 5000 rpm it makes a raddling noise but not really load then I let off and then back in again. That was probably detonation. I may have to use some octane booster but no more leaded racing fuel https://youtu.be/3daAuRW7KDA

 

Which grade fuel do you use?

 

That is a very strange noise!

 

In my experience with detonation/preignition it sounds like a few marbles being spun around in a tin coffee can

 

Just the highest octane

 

The whoosh noise of course was the turbo but just before that not really load

 

My plugs were gaped at .041 and I moved them to .028 that's a big difference in gap I wonder if that was too much

 

With stock plugs, I was getting misfires/spark blowout in boost with stock gap. After gapping the dual ground stockers down to .028 I was getting misfires at idle but boost was clean lol. Threw some ik20's in there (1 step colder iridiums) and no more blow out at all. I had BAD experiences with the ik22's. Suckers only lasted a few hundred miles for me before the iridium tips were burnt off and the gap was huge. I highly recommend the ik20's for 12ish PSI and lower with stock gap (pre-gapped to .044).
Also, what oil and filter do you guys use?
Last change I used 5w30 royal purple with 1/2 quart of Lucas stabilizer and a K&N oil filter and my oil is still clean as a whistle after 6000 miles. I won't use anything else now.

 

Ok, sounds good. I got some NGK BKREIX-11 too. I will install them today. I have an Ultra gauge but I'm not sure how to view the fuel trims.

 

Couple pictures of my setup...Any reason to remove EGR valve?
