Just having a guess here; I presume to make it work on the road a second solenoid valve would be installed that would activate the anti-lag valve from the PCM IMRC output via a multi-tune.

@biddie_fiddler Call there bluff and stay in the house. Quite possible they are doing the sneaky so they can rent it out again at a way higher price. Or on the flip side, the new owner may want to keep you on. Either way, next years problem

2nd time around. Engine out. Learning curves... Lucky bearings are cheap. Clean, clean and clean. And clean. And if you didn't catch on, clean. White rag in, white rag out. It cannot be understated enough. And no matter what you're told, at the very least use plastigauge to confirm you're in the ball park on your clearances. Anyway, moving on from those apprentice things... Oh, and de-pump your lifters. And another massive don't in amongst all the other big don'ts; do not put assembly lube behind the bearings. Yep, 1st class rookie here making all the mistakes. Argh, time is free and the wife is very forgiving. But leaving all that behind, more positive stuff to report. Got a few bonus jobs done. Posted some of these shots in Puffs thread the other day, please excuse the repeats... Lock wired the Pulsar turbo housing bolts. Bodgied up the Pulsar 1mm oil restrictor fitting into the factory oil feed fitting Red loctite and lock wired the flex bolts. I understand the bolts out backing issue is a combination of power level (say 500+) and what the engine is being turned to (say 6500rpm+) but regardless, got in there first. Early worst case, I feel all sorts of vibrations. Research suggests that at my power level goal I should be ok anyway.

Jets tuning thread has 100's of combos with all the mods listed. A very good resource and well worth your time reading through and making a few notes along the way. Take your pick and start saving

@Puffwagon What do you think? You on board?

Only posting to complete the thread. Job done and objective achieved.

Yes, do the springs and surge tank. That set up will get you a long way and probably see you right for the life of the car. With those 2 extra mods and a multi tune you'll be high 400's on e85.

ouch. Not having played with anti-lag myself, not sure how much of a band there is that goes from mid to wild. Should there be room, then first thoughts are it's on your tuner.

Instafamous 🤓

Yeah, annoying. This will work on the flex plate too for the bolts that walk loose.

Going back to my karting days I tie wired everything. I reckon that'll sort the housing bolts backing out. Had the issue on the Garret as well, perhaps not just a Pulsar thing. Note to the new tie wire players, Remove bolts, clean threads, re-install and torque down to spec. Mark all bolts where they are situated and also mark the most logical flat face for the hole to be drilled through. Remove all bolts and drill a 1.5mm hole through the bolt. You need to use a drill press on high speed (1400+rpm works). Best of luck with a battery drill, it can be done with a steady stance and good continual drill alignment. Do a good job, use logic with the hole placement and with the right tools and it can look very professional. (Google Image) (Good price)

Love that price too... $2.20 last time I filled up local.

Just an info post. Installed the old stock high km gears for a test, tip clearance is 0.13mm I.e. about 0.1mm tighter than the Empire gears. Everything else was pretty well the same. Will keep an eye on things and see what the oil pressure ends up settling at.

Excellent timing on the info!

The coolant is an easy one. What ever the service manual says.

Pressure and flow go hand in hand. In the turbo's case it's a function on the oil flow through the turbo bearings themselves. For the orifice to be sized correctly the recommended turbo oil pressure and flow rate are needed. From there you could calculate it (Hard. Differing viscosity / temperature and supply oil pressure) or just do some on car tests at the end of your build. Looks like it would be easy to knock up a cheap nasty spacer plate and tee a remote mounted oil gauge into it. A good sized drain is common sense. Can't go wrong copying what Ford did, it works. Looks to me yours is on point.

ouch, exhaust studs are always a nervous time. Helicoil install in car is never fun. Off comes the manifold I presume?

ooh, righty. Easy simple, thanks for that man! 🏋️‍♀️

Beauty, I'll tell the Mrs to cancel her botox. Best I get around to wiring up my oil pressure sensor and hook it my DLP-8. 7075 is a very high grade of aluminium. They didn't fark around with that design then. Very very noice piece. The adjustable relief would be a nice addition to add to the OEM pump. Obviously can't go too crazy, the housing won't take it. I think I might keep that as a project for when I have nothing to do.

Cool, close enough. Tip to tip he mentions about 7 thou max for his gear, and that oems will have a little more. I'm at around 9 thou. Something to keep in the back of my mind I suppose.

Doesn't seem to be much concrete info that I can see so far. Puff was good enough to link me to the Boundary vid where they gave a wide range of tolerances, but with that they said each tolerance range gives different characteristics. Farken hard to decipher when they give out cryptic info like that. What is in range and what is out of range? Or perhaps more succinct; how long is a piece of string? I think my best cause of action is to scour multiple OEM workshop manuals until I find one that has oil pump specs that I can use to check against OEM. I have reached out to Empire but have yet to here back. What you are looking at here is an FG oil pump housing with around 12 years of k's on it and brand new Empire Elite oil pump gears sitting in place. All dissembled and cleaned to a high spec before measuring. Using a metric feeler gauge set and precision ground parallel for my straight edge. FYI 0.1mm is close enough to 4 thou.
