The water inlet has three hoses on it. The one from the radiator, the heater core, and another smaller one. Where does this go to on a FI engine. I know on a carburreted car where it goes (to the inlet manifold to warm the incoming air), not sure about on the FI car though. Cheers Ray

My 2nd cylinder had low compression, the guy that looked at it said you thought the piston ring from sitting for 2 years was not good. I got it to run and drive finally. The dual webers need rebuilt I think, it was doing alot of spitting and sputtering, not much power, most of the time! Please tell me what you think I should do, are the webers easy/cheap to get rebuilt, and what about the 2nd hole, how much $$$$ do you think it will take? Thanks guys!!

I am building a 280 engine. How much clearance do I need in the piston for the wrist pins? (I have floated the rod/wristpins) One piston seems really tight with the wrist pin clearance being marginal. Will I need to relieve that piston so it is like the others? Or, as long as it pushes into the piston will it be OK?

I thought I would follow up on my damper pulley saga. I had to find a newdamper pulley for my 240z since the integrity of mine was in question.My options I found out was to buy another used one that the rubber was probably shot or buy an after market race pulley for a couple hundred.I found this damper doc guy out in california that rebuilds dampers for all vehicles.It cost as much as buying a used one , and he about guaranteed it against failure. I asked him if it would hold up under slightly higher then stock rpms and he said he would only worry about torque issues. And he was talking big block torque values. He charged me 69.95 for the rebuild which I thought was reson…

Ok, yell if you've experienced this yourself: Whenever the engine is under extreme load in upper RPM, it begins to cough and stumble. Power literally drops as if falling off a cliff. It began shortly after I tuned my SU's and advanced the ignition from 10 init 32 adv. to 13 init 36 adv. I don't believe its the carbs, as the car is running stronger than ever before (until X rpm, as stated below). I tested for detonation by putting the car in 3rd, and pulling as hard as possible up a hill from 1800 RPM. No pinging or knocking. Just a complete lack of power at roughly 5500+ in 2nd, 4600 in 3rd, 4200 in 4th and 3500 in 5th.

Got the thing to crank and start up with some gas-in-a-can. but it won't sustain itself so thinking it's the fuel pump. Where is this thing located? This is my first Z. It's been sitting at my cousins farm for about 6 months. now there's a bunch of snow around it. Trying to decide if I can fix it at where it is or if I need to tow it home (abut 25 miles away) Thanks in advance. -Chee Forgot to mention it's a '72 240Z.

Anyone have an idea of what a fair cost is of an original, used 4spd transmission setup in good working condition? What's the best non-eBay place to get it? Looks like I'll FINALLY be purchasing my Z later this week after a very long search It's an auto and I'm seriously considering the switch. Aside from changing the Z from its original factory specs, are there any other issues/drawbacks to go along with the switch? Is the transmission code even located on any of the data plates? Aside from some aftermarket seat upholstery, the car is basically bone stock. Mike
