I broke it quickly...And repeatedly...Chaste White Rebuild

[Francob]

Stu has sorted the engine, hopefully have it collected next week. Happy new year all.

 

[Francob]

All back home, will whack it back in this weekend or next.

 

[Francob]

We dropped the engine back in today, I’ll spend the next few weeks putting it all back together.

 

[Francob]

First start tomorrow, wish me luck.

 

[Francob]

Back up and running.

Next stop an MOT.

 

[Marky]

Nice strong brap again

Sounding lovely now mate, out of interest - how much did the LINK spot what was happening while the running was being iffy? Was it all over and alert you / shutdown the engine straight away or did you spot it via a gauge?

The Link ECU didn’t help with diagnosing the issue. Well it did help me confirm that the oil pressure was slightly too high as the ECU has a sensor to record that data.

The reason it went back to Stu was because I compression tested it and it was too low and also the oil pressure was too high. So he’s remedied both those issues. The compression was too low mainly in part to me not running it in correctly/long enough coupled with the fact Stu ran wider seal tolerances as I plan to abuse the engine at high rpm. So this time I need to properly run it in and Stu has tightened up the tolerances a tad as well as lowering oil pressure slightly.

But the Link ECU has a shit load of safety features like any decent modern day ECU.

Boost/fuel cut based on any number of parameters that you’ll set. If fuel pressure drops for example or if oil pressure drops. You can add rev limits based on coolant temp, inlet temps and oil temps etc. You can also assign parameters to AFRs too if engine goes lean and probably loads of others that I’ve not even looked in to.

The other handy thing is the live logging which I have used to fault find issues with voltage drop. The logging records everything that’s going on and is really simple to look back on.

I definitely think that you are going to have a highly modified tuned car you need a modern day ECU.

Oh definitely agree with the last part 100%, I was just curious as I'm lining up a LINK for both cars of mine.

I was curious as to how "on it" the LINK was in helping you spot an issue which sounds "very" because a parameter had been broken and that then let you sort it rather than grenade the engine.

 

[Francob]

Yes the Link certainly helped me to realise oil pressure was a bit on the high side.

I hope I never have to rely on the other parameters that we set during the next tuning session but good to know I have those fail safes.

 

[Marky]

Just out of interest what are you classing as too high oil pressure?, what rpm?

 

[Francob]

Just out of interest what are you classing as too high oil pressure?, what rpm?

Was seeing 110-120psi at 3-4Krpm in 5th when hot.

 

[Marky]

And what has it been reduced to now then?

 

[Satoshi-FD3]

What bonnet is that you are rocking?

 

[Francob]

And what has it been reduced to now then?

Haven’t driven it yet

Not much but a little bit, cold start was 90psi, up to temp was around 60psi at idle. Driving it to MOT sat.

 

[Francob]

What bonnet is that you are rocking?

Seibon ST carbon bonnet.

I picked up a Re-Amemiya style front bumper the other day, not sure if it’s legit or not or even if i like it yet, either way it’s going to need a decent amount of chopping to make it fit with my front mount. I may try and repair my OE one or find another style that I like.

Ive been trying to resolve an oil leak issue with turbo oil return. I’ve just refitted it but currently charging the battery so I can test to see if the leak is sorted.

I am nearing readiness for an MOT but I think I may need some welding done on pass side rear inner sill.

Also met @Tangelos yesterday who bought a carbon front splitter from me, I think it suits his car well.

 

[Francob]

I picked up a second option for a front bumper this week. A genuine Re-Amemiya, I think I prefer it as like the front lights and the larger opening for my front mount.

 

[Francob]

Also had my first MOT since owing the car today. It failed in two bits that I knew it would fail on and that’s having no rear fog light, easy fix this week. Also a small bit of welding needed on under rear sill.

Other than that it’s all good, will get it all under sealed

 

[Francob]

New tyre day, went with the R888’s.
