I'm reading an article in one of the cruise magazines that we have here in Florida. The name of the article is "10 Engine Wives Tales Debunked". #2 Fuel injection always makes more power - Fuel injection does a great job when throttle position changes often. For types of racing where the throttle is wide open most of the time (i.e. drag racing), a carburetor is a formidable opponet - especially when matched against throttle body injection. I know what fuel injection is and I know where the throttle body is, but what is "Throttle Body Injection". Is that whats on the FI Z's? Vicky

I've got a 260 that I just changed the carbs over. The price was very right, cheaper than SU's by a long shot, so I now have dual webers on it. I've got them tuned (don't know why everyone bitches about that) and her idling nicely. When I was doing the tuning with the engine running, it sounds like something(s) is clanging inside. Not pinging, but kinda clanging. My neighbor says it sounds like my lifters are bad, or I've thrown a bearing. Can anyone elaborate, or offer some advice? It looks like my valve gasket has been leaking oil slowly in the front for some time judging by the greasy depositing that goes down that side of the engine. Meaning, I will probably…

Howdy, My 240Z was in storage for about 6-7 years. I changed out the coolant and oil. I removed the carbs and cleaned them. I also drained the gas and put in about 8 gallons of 91 octane. I put gas into the float bowls and it started up and ran wonderful. I drove it for about three miles and then it died suddenly. It started up once more and died about 15 seconds later; this time for good. I pulled the hoses that go to the carbs and cranked the motor. Gas is getting to the carbs. What should I check next? Thanks, Steve

I got a 71 240 with the original engine in it, hooked up to a newer 5-spd tranny. Original SU round top carbs. I'd like to build a new motor for it, for the purposes of cruising on sunny week-end road trips. I'd like to keep it very simple, and dependable such as it is now... No complicated fuel-injection or turbo setup, or such. I've been thinking about a stroker motor, but after reading this article http://www.geocities.com/row4navy/engine.html on a 3.0 stoker it appears that going that route might get pretty pricey to do it correctly. Does anyone have any suggestions on what a good motor build for about 2-3k, with good low-end torque for crusing around would be?? Than…

Several days ago I posted a question about a certain West Coast supplier and received a number of replies stating why I should not do business with them. I am in the process of building an F54 turbo motor and will be spending several thousand dollars on internal parts and engine management system. Please recommend other parts suppliers who can help me. Thanks for your input, mayolives.

Checked compression and there are 4 cylinders at 160 psi, and 2 at 60 psi. Any tips for that? is that worthy of a more expensive engine re-build or can i do a cheap individual rebuild?

Was just given a 1982 280ZX that has been sitting for 20 years. The body is rusted beyond repair, but the engine only has 36,000 miles on it. This is the engine I would like to put in my 1970 Z (without the fuel injection). What should I do before running the engine?

Supposedly the motor in the Z I bought has the L28 block and L24 head. I was wondering what the figures would be on that setup, like comp ratio and HP/TQ, common problems stuff like that. The car doesn't run right now, it's been sitting for a while, I think the carbs are just clogged up and nasty but who knows. Any info on this set up is greatly appreciated
