Also took a few pics showing some CNC details I love on my engine

Well it’s not been a straight forward couple of days! A mixture of expected and unexpected issues have made for very slow progress in the reassembly process. Issue #1 (unexpected) I’ve installed the dipstick tube as per usual and obvious gone to install the dip stick... only to find if won’t go all the way in and I can hear it fouling against something metal inside the sump... how odd. Message Mitch to find this is an unheard off issue to him with all the main caps kits he’s sold. So I try rotating the dipstick and it drops in. Sweet. Go to pull the dipstick out with one finger and it instantly grabs and releases leaving me with... What the eff! The measuring weight at the end of the dipstick had come off leaving me no option but to have to remove the sump to retrieve it.... balls.... but at least I got to see my engine internals first hand Managed to retrieve the end without any issues It appears to be a clearance issue between the girdle and the pickup that’s grabbing onto the dipstick. Obviously I’ve made Mitch aware and much pondering is being hand as to how to resolve the issue as easily as possible. Issue #2 (expected) I’ve then moved onto rebuilding the turbos. A new one for me as I’ve never rebuilt a turbo before. While the assembly is straightforward enough, getting the “clocking” of the housing correct look a bit of trial and error Issue #3 (partially expected) Onto installing the turbos and the issue became apparent As with all after market parts, tweaking is always required, and I come to expect it. So to solve this I cut down the drain pipe just before the upward turn, flared the end and used a section of reinforced rubber hose to join up the drain to the sump. Didn’t have chance to take a pic as was a little stressed out by this point. Issue #4 (unexpected) Assembly moved on, to find that I was missing a few parts that I’ll need to finish the engine before it goes back into the engine bay. A few of my PCV hoses, thermostat and couple of the Plenum bolts had been missed during the packing process. So I’ll have to wait for them to arrive to top and tail the engine before installation. So as it stands, the engine currently looks like this Plan for tomorrow is to get the ancillaries back on the engine and get the belts on. Then I’ll make a start on the wiring loom and refitting the interior.... hopefully tomorrow will be a little less stressful!

She’s home! I’ll post more pics tomorrow, been a hectic day...

I repainted mine, it’s in my build thread

No mate, just the complete engine

29ft 7 and a bit inch’s of DEI reflect-a-Gold tape later... The IC pipes were fairly easy to wrap nicely.... the turbo intake pipes were simply impossible to get a crease free finish on, simply too many angles and shapes to contend with.

What points are they measuring from? I’m assuming wheel centre to wheel centre?

What a per-lava getting my engine collected has been! Was meant to be collected last Tuesday by FedEx, and after lots of excuses and £235 of international calls to get them to do their effing jobs, they finally got their arses in gear and picked up my engine. (Don’t ask... it’ll take me too long to explain, and yes, I am seeking compensation) All being well, it’ll be here on Monday

One too many dugga duggas.... titanium isn’t known for its ability to stretch!

Came out OK

Haven’t decided yet

Coming on nicely

I’ll more than likely ceramic coat (like my hotside parts) the Plenum in the future. But time is of the essence at the moment and I do t have time to sort that before it goes for mapping on the 30th Sept. As for painting the top of the Plenum black. I’ve pondered it. While black is quickest at loosing heat, it’s also the quickest at absorbing heat. The air charge going through the Plenum is probably doing a more efficient job at removing the heat from the Plenum (to the detriment of the air charge temps) so I think I’m better of focussing in reducing the amount of radiative heat penetrating into the Plenum than increasing its ability to absorb and then radiate that heat. I think in an ideal world, there would be some sort of heat shield underneath the Plenum, but I think that would be really tricky to make so it fit around the cam covers, coil packs etc etc etc

No reason why you can’t post here

Any pics of the car?

So while I’m waiting on the engine, I have again decided to wage war against heat soak. The first battle front is the Plenum. While everyone like a polished Plenum, I’ve decided to take it one step further Yes, that right, I’ve started polishing the underside of the Plenum....... But why I hear you ask? Ok, in the engine bay we have to battle against two types of heat transfer, conductive heat (something hot touching the part) and radiative heat (something hot near the part). When it comes to the Plenum there’s nothing we can do about conductive heat transfer as it has to be bolted to the engine. Radiative heat transfer on the other hand, we can do something about.... Most will know that Gold is the best substance for reflecting radiative heat..... and I shall be using this on my intake pipes on the engine bay. However, wrapping the Plenum would be a serious pain, require a lot of tape and probably look a bit ****. #2 in the substances best at reflecting radiant heat is, as luck would have it, polished aluminium..... which is generally rated at anywhere between 95-98% as effective as gold at reflecting radiant heat transfer. Highly polished aluminium has an emissivity coefficient of 0.035 vs polished gold 0.03 Given that polishing the underside of the Plenum costs me nothing but time and effort, I figured it was worth a crack. I don’t think I’ll reasonably be able to polish the underside entirely (tricky areas around the PCV, water pipes etc) so I’ll focus on the runners and anything else I can get to with a polishing wheel. Can I prove it’s of any benefit..... no.... but there is science behind what I’m trying to do, so it’s worth a punt. Even it reduces intake charge temps by 1c, it’s been worth the effort

Have you got the emissions report? What are the numbers?

Then I can pretty much guarantee that’s its been tested to the wrong standards, pre Aug 95 Z’s are subject to a Non Standard emissions test (aka non cat test). However, you need to make sure your V5 has the manufacture date as Feb 1995z Search the forum and there should be a post by me about what standard our cars are subject to with supporting documentation from VOSA But by the sound of it you’ve got bigger issues to deal with

Cheers guys. Shippings all booked, fingers crossed it’ll be here beginning of next week.... not sure it’ll be fitted quite as quickly as JaiKais was mind

I’ll see what I can do

Kinda need the engine in the car to get to the NEC :lol: But I know what you mean, would be a cool thing to have on a stand.... I should have had two built

Yeah, a quality tyre as well, something like a Wang Li or Triangle :lol:

The time has come to ship it home to me! Hotside parts ceramic coated to help fight the war against heat in the engine bay aswell as improve spool in these GT525’s. The exhaust ports and manifold have been gasket matched to optimise flow. FedEx should collect it on Wednesday this week, and 6 days later it will be in my hands

Same as the above, chuffed to qualify for this event and looking forward to showing off the years of development that’s gone into my car. Also, great to see so many people voting! See you all in November!
