How to tell me you haven't raced a S or R chassis without telling me you haven't raced a S or R chassis.

Excuse for an epic road trip? I expect a few people would be thinking of doing that given the price.

Yes.

All of that material you found hard to remove is hard to remove for a reason. If the factory could get away with using paint I'm sure they would. If I was doing the repair, I'd be looking to replace the sealant I had just removed with something equitant or better.

So when you say painted, do you mean sealed with something like rhino lining or line-x?

This is not going to be a cheap exercise, even if you shoot for an OEM rebuild. I would strongly consider doing everything properly the first time... Get the big boy pump, get the baffled and extended sump, setup the breathers properly, etc etc.

What was the usage like with this car? Was it a track car? Did it see much time bouncing on the rev limiter?

Did the machinist give any indication as to why the head failed the way it did?

What was done to check it?

@ChrisW434 If tuning is new to you, this might be really useful - https://evansperformanceacademy.vhx.tv/ They run a subscription model, so for $50 USD you get access to 100% of the content. Turn it on, watch like crazy for a month and turn it off. The value is crazy. This is how I learnt to tune many years ago. Since then, I go back to the site every couple of years to catch up on new content. I wish HPA ran the same pricing, they are so expensive in comparison lol.

If we wait another 5 years maybe Chat GPT can just sort it all out for us lol.

@Watermouse The exhaust setup your describing isn't street legal. So if you're going down that path, why bother with the cost and complexities of the varex? You could just run the screamer and if you see the fun police, don't drive on boost? Or if you want to be street legal, you could get a swappable setup v-bands etc, and run the screamer on track and plumbed in on street?

It takes about 5 seconds to twist and remove that breather.

I'm so keen to see how it turns out!

About $3.50

What is the long term plan for the car?

Can you go for a drive, log all the channels and post the data up?

The message here essentially is, your fuel mixture and ignition timing can be crazy far away from being optimal however the car feels fine to drive. He isn't talking about the physical timing belt when talking about timing not being correct.

Do you have a fuel pressure sensor?

Yep, see attached Yep. For example, you buy a Haltech ECU and upload the Haltech base map, the car will start and feel ok while driving however will have had 0 tuning done (provided the car is essentially stock, the base map will line up). If you get a few seconds spare, please remove the passenger kick panel and solve this mystery for me lol.

Ah ok. It would be a lot more accurate to simply say, the car has not been tuned. Blowing black smoke on boost is so crazy far from any state of 'tune' that I would not even call it poorly tuned. Do you know where the ECU lives? It takes about 10 seconds to access the ECU and we could solve this mystery.

and this Just don't add up for me. What is the go with the tuning on your car, who tuned it? Was it put on a dyno? Also, I'm still waiting to find out what type of ECU and boost controller you have lol.

What boost controller/ECU are you using?

Can we not just turn the boost down until you get the car tuned?

@Tillis3 Any luck with the thicker oil?
