So am going through my settings of  my management and trying to figure whats best suited for the fan to be activated for my engine. I got a 16" fan on a 2 core rad....

After monitoring my temp sensor reading it sits around 85c on idle. Should i activate the fan to come on at 85 or activate at 90-95 then shuts off at 80 or 85 ?

I would just have it come on about 85-87 and off at 80 or so.

Doesn't matter of NEOs run hotter or not, if you're not applying any timing or fuel corrections for warm up at those temps then you can choose what operating temperature you choose.

Just remember to run a R33 thermostat instead.

I'd run them a bit hotter otherwise they will be on virtually full time.

If you're using a R34 thermostat as I mentioned. I have a R33 one which opens at sub 80s instead of close to 90 as the factory NEO.

      Can we see a scan of the original quote? The problem with engineers (and by this, I mean, all engineers across all engineering industries) is that there are "engineers" and there are "engineers" (you'll have to imagine the two different vocal emphases on those two versions of the same word. Engineering is a mindset - your farm kid who spent his life rebuilding the tractor will likely make a good engineer. The farm kid who spent his life taking photos of butterflies.. perhaps not. But on top of that mindset, the modern engineer has to learn how to write so that there is absolutely no way of being misunderstood. Proposals/budget estimates/quotations are one place where this is absolutely vital. You have to delineate your scope of supply with extremely hard boundaries, and anywhere where there is any possibility of not being able to have such a hard boundary, you need to write language that will cover you from scope creep, cost overruns, the inevitable interference of the client or their "engineer", etc etc. Now, if your clients are the BHPs and the Rio Tintos of the world, and similar, then you get good at this. If you are an automotive engineer, pitching work to the great unwashed masses, your skills in this area might not be well developed, because you're only dealing with knuckle draggers trying to get a big block legal in a Torana. And when I say "might not"....I'd suggest there's a better than even chance that any such skills might be completely absent. So, we might be able to look at your quote and see what the opportunities are for rebuttal.

      Thank you for this my turbo doesn’t have the nipple so I’ll get one installed in the turbo to Intercooler piping. I’ll get everything I need and locate it all using the information you both gave and get back with an update.

      Please do not connect it to your manifold. If you do, as GTS suggested please record the lot in 4K with good mics attached.   On the factory Skyline, there's a upside down pipe that allows it to breathe, looks like this

      For me I'd need some serious justification for why it has blown out.  Have you questioned him on it?  To be honest if you didn't question him right from the get-go on the first invoice that was already way over the initial quote and then you've (presumably) then paid another $1375 on top of the first invoice, then you're pushing shit uphill to get a favourable result now... It was years ago I last got an engineer out but it was around $450-$550 per visit.  That was just to inspect each progress point he gave me for the project.  Is he just doing progress inspections or is he providing engineering diagrams, technical assistance, etc??  If he's not, he's a filthy rip off merchant.  If the $3100 is the final sign off then you need to cop it on the chin, pay it and move on.  If it's not, piss him off and get a new one.  Not many Jeeps I'd value at $10K full stop let alone just engineering fees on a written off, half actual value WOVR Jeep....
