[Vortech Heads]

Ok...sorry if this is the wrong area to post in...but...

 

Is $250 (shipped) for a set of Vortech 5.7 heads a decent deal? The guy also has a roller rocker setup for $100...

 

Also...will a TPI setup work with Vortech heads?

[waiting and waiting...]

The engine I just sold had a higher lift/duration cam in it.

[waiting and waiting...]

NOTE: i wonder if the springs can be changed to a tighter, stronger spring so an aftermarket hotter cam can be run?

 

Funny, I was wondering the exact same thing. Keep us updating on how your HLA's turn out David. You know I've been interested in repairing/rebuilding Datsun HLA's for a long time and I'm glad to see that you're taking it to the next level.

[Block hugger headers]

At $75/pair the Summit Racing headers look good...but...has anybody ever used them and experienced any problems in a 1G Z?

[Top-End Performance comments on company]

What did they say when you called them about the condition of the parts?

[waiting and waiting...]

a spring? Oops. The lifter I had that was semi-taken apart when I got it was missing the spring, I guess I better go see if I can find it.

 

err...wait...maybe the spring was there...I seem to remember the lifter wanted to push up...

 

Can you post a pic of the spring setup? Does it fit at the bottom of the housing assy? or does it fit up into the piston part?

 

I wonder if a heavier duty spring will help, too...

[You guys remember that n/a electronic blow off valve?]

Hmm...that would work well with my side exhaust tips, fake front mount intercooler, fake BOV, and my 10" bazooka that is disguised as a blue NOS bottle...

[never cleared the tree on the first try]

Are there no stronger aftermarket axles made for the Z?

[finally fired the v8.....but]

Is it carbed or FI?

there's a page showing the blow through box

[Supercharged L28 Project 2 (please read)]

I found this page on how to modify the carb for forced induction.

I'm still looking for page on building a box around the carb, but, I've seen it done before.

BigWhyteDude...

There's only 3 things that come from Georgia...

 

Fruit-pickers, Picnickers, and Dick Lickers...

 

...and I don't see you carrying a basket.

[waiting and waiting...]

David is right. I'll try to find the TSB I had posted before.

 

Before I begin..."lifter" is really an erroneous name for the parts in question. They are actually Hydraulic Lash Adjusters (HLA)

 

Most of the time your HLA's make noise for 2 reasons.

 

1) Inferior oil filter...I've seen HLA's quiet up by simply using a good oil filter.

 

2) sludge build up in the HLA's itself...this can be cured by simply soaking the lifter overnight in kerosene or diesel.

 

On that note...I actually took apart a P90A HLA to examine it and see what the potential problems are. It's a fairly simple design. In effect, you have a pressurized oil resevoir that via oil pressure pushes up on the cylinder (much like a brake piston). If the oil ports in the HLA get clogged then what will happen is that you won't get proper oil pressure within the HLA itself...

 

If I'd have kept my old engine and the HLA were bad, I was going to experiment withing slightly drilling out the oil ports to make the a little larger to help oil fill up the chamber more quickly. This method was actually put in use by Mitsubishi for their newer style HLA's.

 

Other than that, the only thing I can see that would go bad is if the walls of the HLA itself wore down slightly, not allowing a good seal between the HLA housing the HLA cylinder. Although, I don't know if that would happen...I dunno...the parts are machine with tight tolerances. In either case, I believe that opening up the HLA ports will help...of course, before I did that, I'd soak them in diesel/kerosene over night.

 

I have a special tool for removing lifters from the cylinder head without having to pull the cam or go through any extra work, but, I belive you can probably use a big screwdriver or small prybar to achieve the same effect.

 

If anybody is interested I can post pics of the tool.

DAMNIT!!...

 

 

There was another V8 Swap Meet today and I didn't know about it!!

 

Talk about coincidental!!

[Satire]

All respect restored.

 

Thanks for that clarification DAW. It is much appreciated.

[Found 84 Grand National w/ complete running gear!!!!]

Somebody told me the engines were the same, but, the later ones were intercooled...I can neither deny nor verify this.

[Focus Hybrid]

There's actually a conversion kit available for the focus to drop a 302 in it.

ps...it's a completely bolt in kit. No welding or fabbing involved.

[L6 pollution of TURBO/SUPERCHARGER forum]

There will always be a home for 6 cylinder powered hybrid Z cars.

 

Speeder is right. Respect has definitely been lost amongst some members.

 

Damnit. I wasn't supposed to read this thread anymore!!

[Where to get engine/tranny]

I think the one I went to I think I saw a flyer at Autozone...but, you might try calling some performance shops or something like that to see if maybe they know of any.

 

If there's a racetrack around town somewhere there's usually one after major races, or at least that's how it is here.

[here's a frontend idea]

...or maybe a nice big front mounted intercooler..

[Where to get engine/tranny]

Yeah, you might actually try the parts section in your local newspaper classified ads section. Sometimes there's some great local deals in there.

 

Also, alot of places have V8 swap meets. I already had an engine, but, at the last one we had here there was a completely carbed 350 for $200 from air cleaner to oil pan.

[here's a frontend idea]

Looks nice. I think they'd sell.

[Rear Drive 2.0 Zetec I-4]

I looked on the quad4rods site, but...all I could find were quad4 bellhousings...

 

do they bolt up the Ztec block like in the pic?

[Idea for installing Honda S2000 VTEC motor into a Z...]

Holy Crap.

 

Ed Bergenholtz went Mazda!!?!?!?

[I can quit biting my nails]

Ok. I have the same thing going on with my Ultras. Love the wheels, but, they haven't been made for quite a few years...my dilemna is that I want to get fender flairs in the future, but, hate losing the wheels I have in the process. They are 16x8's with a custom offset.
