Daves new school holden shambles.

[Muncie]

I was rummaging through my AN fittings today seeing what i was missing to get water cooling going and took blow off valve out of box again and tried in various places.

Fuck sake 3 hours too late.

All the missing bits for above are now on way.

Back to NA For a bit I'll work on the off boost tune till everything is ready.

[shrike]

Might be able to just replace the bearings?

[Muncie]

A bearing kit is $205 usd hopefully that's all it needs or a gen 2 supercore is $1100 nzd at least it's not ultra munted. I'll pull to bits this week see how far I need to go.

 

[Muncie]

Ok, it's full of expensive junk..... core is almost a grand front and rear housing survived fine so at least I don't need to rebuy those. 

Sorry credit card......but you got this.

On a serious note had turbo off sitting on bench and car back to NA in under 5 minutes glad I used v bands on everything makes working on this thing a piece of cake.

Lesson learned kinda knew could happen its going back on with 30 Micron filters watercooling and a BOV. 

[Muncie]

Bit the Bullet and just bought a supercore, so everything bar the exhaust housing on further inspection the other one is rebuildable but I'll leave that for a later date. Maybe my son wants it or I go nuts and twin turbo the L67 and make 1500hp. 

Whatever problem solved with new parts and a new addition to the shelf of shame in garage.

[Muncie]

I think an arduino project might be worth doing for some engine protection so I can monitor some temperatures and pressures and kill the power to engine if it goes outside of parameters.... I've only got 1 spare IO on pcm and it's not an overly fast one either.

Yes I know it really should be running a Haltech by now but..... well this works OK for what I need and keeps everything on can bus talking as I hate things that don't work properly.

I think I might have low oil pressure so I need to dig a bit deeper there get some data, unsure if turbo died due to low flow from reduced pressure or just junk blocking the restrictor or the restrictor blocked up after the bearings failed as is a few bb's went missing. Either way I can't afford to do this often.

Should have supercore tomorrow hopefully.

Well I got the shits about frying another turbo so bought a turbosmart OPR2 oil pressure regulator as it has a built in 44 micron filter so it's 2 birds one stone deal. 

I did order a filter but that restrictor could get blocked if I dont regularly check it from just carbon build up over such a small orifice, im not playing this game again..... i can just drill out the restrictor and let the reg do the work and also have a gauge or pressure sensor inline keeping tabs on stuff.

I've got to tap in some water feeds and mount that Blowoff valve so that will keep me out of trouble water feed AN6 lines are coming.

Trying Aliexpress parts for the waterlines  but will stick with Speedflow fittings and line for oil.

[Muncie]

OPR arrived today so fitted a nice little stainless pressure gauge to it so i can keep track on pressure at the turbo and offered up to old turbo to see if it fits mounted straight to the oil feed, I run a turbo beanie so it doesn't actually get that hot there.

Sweet little unit.

[Muncie]

I've had these two old school Greddy gauges since I was in my teens might just fit them in dash I didn't want extra gauges but the product I've been on pre order for over a year is only getting released to the USA initially and well i need working data now.....

If anyone can tell me what sensors a Greddy temperature an oil pressure gauge use let me know as I've long since lost them.

[zach_munce]

Ah my bedroom will be losing one of its performance parts still have the oil cooler tho

[Muncie]

Its back together and making lovely sounds again. Now running a Gen 3 turbo PSR3584RS original was Gen 1 GTX3584RS New one is rated for an extra 50 hp and has one blade less on impeller hopefully that's less mass and I see boost a little earlier. It's also better build quality notably has zero shaft play original out of box bugger all but some.

Have hooked up everything and started car to check leaks and oil pressure at the new oil pressure regulator which at idle i have 35psi which is ample no restriction in line now and a filter so turbo should last for years.

Was slightly worried about tapping in to the top of thermostat housing but it flows well at idle should be a stream once thermostat opens.

Had to take little gauge off as it doesn't quite clear bonnet have confirmed system is working properly so job done.

I need to take off my bottom radiator hose and weld an AN6 nipple to complete the coolant loop. Piece of cake though then it's ready to drive again.

Far out, that didnt take long! 

Be interesting to see the difference

I'd love to pick your brain about a 3d printed collector as I'm pretty sure my crossover is choked at the manifold as it necks down to 32mm from 51mm.

It works at 10psi but I intend to build a new long block and run 20-25psi in future its going to choke itself 

[Roman]

Any time man.
 

[Muncie]

Quick first drive today just up around block to get thermostat open and any bubbles out of cooling system. Sounds quite different turbo spool is much higher pitch seems a bit more responsive but I wasn't really testing it at time.

Turbo looks like its on life support with so many hoses coming of it......
