I think I would like to replace my fuel rail instead of spending much time cleaning & polishing because I think the sanding might weaken the tubing. Does anybody know of any manufacturers? Something with fins and shiny/chrome? I saw the JSK one, and it would work, but it looks like a huge thing. thx

I have some Dupli-Color 500 degree engine paint. Reading the label, it doesn't say anything about primer. Their web site doesn't mention primer on engines either. What would you suggest? Is this stuff supposed to go directly on the bare metal?

Who is a reasonable supplier of L6 pistons? I have a set of pistons that the engine builder "mocked up" and told me the pistons were at deck height. When he put it together he said the piston is down in the bore .050!!! He calculated the cr to be 9.3 and now he says it will be 8.1. It will be perfect for a turbo but I have no such plans. I do not want to spend $600 on a set of custom forged pistons. I am happy with a good cast piston. What do you guys recommend? specs: 87.5 mm bore with a 83 mm stroke = 2995 cc

Hi, Been searcing around for an intake manifold for my L28 engine. I'm replacing the original for many reasons, mostly because it is the current bottle neck on my engine, plus it's ugly.. I have found two promising; Arizona Zcar's intake manifold that i want, want, want, but they have been out of stock for over a year, and I'm getting a bit tired of waiting. Then there is Racetep's tripple throttlebody assembly, but it's a bit pricy (2300+tax...). So if somebody has something raceworthy lying around, or if you have any good ideas where I could find one, I'd appreciate it.

I've going to do all the belts while i'm converting the alternator to a ZX unit. Since i'm so close should i do the water pump? The car has 82k original miles and the water pump shows no signs of it not working (No wobble, noise, keeps cool). Should i change it since i'm there or leave well enough alone? It looks to be the original unit. Also, the PO supplied me with 3 brand new belts, but they must be 10+ years old. They look perfect (No cracks, ect) Do you think they're still good? Thanks, Jay

What is the maximum amount that a flat top piston can protrude above the deck at TDC After installing my pistons I am seeing a positive height above the deck of between 0.008 and 0.010 of an inch (8 and 10 thou). I am using a fel-pro gasket that, uncompressed is 50 thou and compressed should be 40 thou. Does 40 thou - 10 thou (30 thou) = trouble or will I still have enough to give adequate piston to head clearance and tight enough to give a good squish area. If this is a problem would I be better for safeties sake to us a slightly thicker head gasket ?? Once again Phred if you’re around I would really appreciate your input Ta

Since the air in the intake chamberis at a closer temperature to what goes passed the injectors and into the cylinders, wouldn't it be a good idea to move the temp sensor from the AFM to someplace in the large chamber of the Intake? thx

Okay, i guess my freeze plug(s) on the back of my engine have cracked or have holes. It has been going through antifreeze quickly and its been dripping from the bottom around the mounting plate. Has anyone ever had to have this fixed on their car? About how much may this end up costing me. Im afraid i don't know enough about this kind of thing to do it myself. Im guessing the transmission is going to have to come out, right? any help? im scared i may not have enough $$ to get this done.

Can you get the plastic Air duct tube that I see in the FSM for the 280Z? I think it might be good to have one because otherwise it's sucking hot air from the underside of the hood. Maybe you could even substitute something else. Other that that, trying to get cooler air to the intake system requires a ricer-type c.a.i. system. thx

I've been taking certain pieces off the top of my fuel-injected L28 engine and cleaning them individually, and I plan on re-installing the stuff before I go after the injector rail. So far I took of the AFM and the Aux air regulator. there were some steel brackets that I removed that hold hoses in place. These were 'protected' by a layer of crud, but after cleaning it looks like it's bare steel. I'd like to protect these in some whay before I put them back on. I've heard of people soaking chain in ATF or some mineral oil or something to prevent rusting. Any thoughts? I'm going after the fuel rail soon. Engine looking too nice now to drive around and re-rust them. …
