One more added.

I just joined the self P/P crowd. Got everything off yesterday ready to go. I found some old mouse turds under my coils. Found the source of my small oil leak. Just old injector housing gaskets. I couldn't remove the screws that hold the coolant horns that bolt on the side of the injector housings for fear of snapping the heads off them so I just remove them together. I would like to get everything repowder coated while I'm at it. Valve covers, plenum, injector housings. What kinda $$$ am I looking at to have it done for the stock finish?

I'm at 342rwhp 336lb ft torque last time It was dyno'd. Best 1/4 mile was 13.05@111mph. I still don't have headers yet. I just put the Fidanza on So with the P/P and headers plus retuning I don't know what to expect but I'm sure it will be better than it is now.:cool:

I don't remember who it was here on the forum, but awhile back someone made a very astute observation of the OEM gaskets for the coolant pipes to injector housings. They noted the silicone bead on the OEM gaskets did not seal completely AROUND the bolt holes. The added thickness of the silicone bead doesn't allow for full compression of the gasket where silicone is not present and lets coolant seep into the bolt threads. Presto! Corroded steel bolts in aluminum & a problem that found a place to happen.

Point of all this rambling is, don't use OEM gaskets for this application (use www.jerrysgaskets.com ). A little plug there!:thumbsup:

Stainless steel bolts would also look good & last. The size is : M6-1.00 x 50

I agree. I could always take them to work and slap them on the mill and drill the siezed up screws out to put stainless ones in. Hell! Why not. Might as well. Cuz at some point down the road I might have to take them off and I'll be confronted with it again. Speaking of gaskets Jerry I'm going to have to order some from you. And all of the injector Orings.

1.) All Injector Orings.
2.) Air horn gasket.
3.) Throttle body gasket.
4.) Two 90 degree breather hoses(mine were as hard as a rock).
I've already got injector housing gaskets.

Whoa Whoa Whoa... the breather hoses are available? Last I checked about a year ago those were totally impossible to find! I didn't see any on the gasket website, but it's fantastic to see that there is a decent aftermarket source for gaskets now too!

Anyone want to work on making a vacuum spider?

Breather hoses... I need a beer if these really are available.

[Ccmano]

Get your beer :cheers: out cause here are the breather hoses.....

Jeff Flint is the guy to contact about powder coating. He just did the top end powder coating for one of my ZR-1s and for 2 of my brother's ZR-1s. He can do any color you want. his website is www.pnwzr1.com

I agree completely, his prices are way, way over inflated. I mean, seriously, $389 for a standard vacuum hose kit?? It's small plastic hoses and rubber pieces. He has no respect for the ZR1 community and seems like he just wants to squeeze every dollar out of us that he can.

I will not be giving him any business unless I just can't get it anywhere else. Which is what he is counting on probably. :mad:

PM'd you. Don't want to get too far off topic.

I was thinking about going with Jeff. The powder coating work that I've seen of his looks really nice.

Jeff does great work,is a super fair, great guy,that knows everything about our cars,and is always willing to give great advice.

[tf95ZR1]

By P/P I assume you mean plenum pull, not port and polish.
As long as she's opened up, why not send the top end
to Locobob for porting and polishing? He works with Jeff
and they are a great team! Its the initial bite of the mod bug!
Add headers, exhaust and chip and you can add approach 400RWHP!

[USAFPILOT]

So you are going to do it...i want to see it in action...want mine while you are at it?

By P/P I assume you mean plenum pull. No! I mean port and polish myself. A freind of mine let me barrow his ported and polished plenum and injector housings off his Z thats pushing 429rwhp just so I could study them a bit. It's not rocket science thats for sure. I'm not rich so I have to do as much as I can myself.:thumbsup:

[rhipsher]

So you are going to do it...i want to see it in action...want mine while you are at it?
Yep. And you can see it. I can already tell its going to be allot of manual labor. And I'm going to go through allot of 80 grit flapper wheels. I bought a nice 160psi craftsman 33 gallon air compressor and a craftsman professional 3/8 air ratchet. I've already got a 1/2 and 3/4 drive chicago pnumatics impact wrenches but I never had a compressor to use them with. I don't know how I ever got along without them. OMG its gonna make working on my cars so much faster than manually turning ratchets. Very very nice.:thumbsup:

I'm of the general notion that these cars are just that... cars. It's quite hard to screw something up so bad that you can't fix it. They should be worked on and used, not just collector pieces. That being said, I think it takes balls to start screwing with plenum and IH geometry in an un-fixable way without ever having done anything like this before. My hat is off to you DIY P/P'ers.

[rhipsher]

I took my injector housings to work today and mounted them on an angle plate on the mill and machined the heads off the 8mm torx screws. It took some work to break the gasket seal and a little prying to get the coolant horns off. The screws were so severly corroded that while I was working them back and fourth off the screws there was red powder coming out everywhere. Tomorrow I'll drill the screws out and chase the threads. Then I'm going to have to flycut .02 off the mating faces. The edges got a little dinged up prying them off.

[WB9MCW]

Nice that you have the ability to do this work yourself.

[A26B]

Considering you have access to all these fabulous machine tools, why don't you set up and bore the plenum & inj hsngs to 36 or 37mm (whatever the finished dia is going to be) about 0.500" deep. That way you don't have to be concerned with keeping the diameter round and properly matched to the mating part. Will also keep the potential for mating surface damage very low since you won't have to do hand port work in that area. Do the hand work deeper & blend to the machined bore. You will end up with perfectly matched ports. While you were set up, you could also mill out the biforcation between the ports & then just smooth out & finish the knife edge in the center.

Would save you a LOT of hand work & will end up with a superb job.

Just my 2c worth.

I thought about doing that. It would be nice to know the X Y locations of the ports. Jerry all I need is the injector housing gasket sketch dimensions old buddy ol pal. I know you have them. Other wise I would have to use calipers to get a ball park. I'm also goint to need to machine that thick finalic plenum gasket to 36mm also. Having access to all the machines is just one of the perks to being a machinist. I have to squeeze the ZR-1 parts in between other jobs. And sometimes I just have to wait.

[rhipsher]

That's exactly what I need to know. Otherwise I would need to indicate on each bore. That's 48 bores all together. That print will be a huge time saver. Thanx Jerry.

[USAFPILOT]

so...when are you going to be ready for mine. :cheers:

Okay, so maybe you're not the typical DIY'er.
