Hello, I have two Crown turbo kits. I am posting these pics for your enjoyment. Sorry, I do not have any info of how they ran other than "stories" from previous owners. Due to financial limitations I have not been able to maintenance and run these kits myself. I am keeping them for the future when I have money to run them. I am building a period correct modified 260z, except for some of my suspension which is modern. Crown turbo kit -Rajay turbo -SU carb w/ airhorn Crown turbo kit -Rotomaster AR/60 -Weber 45 dcoe w/ Crown intake adapter Rajay "J" pipe vs Rotomaster AR/60 "J" pipe They are offset differently, you can not use one on the other. If y…

Yesterday I replaced the belts, radiator, hoses and alternator on my early 71 240z. Now, when I turn the car on I hear a loud squeal right as the car turns over. I'm thinking it could involve something like a belt rubbing, but I'm not completely sure. Does anyone have any suggestions?

Water in the oil! I have an engine out of a 74-260 Z that reportedly has a blown head gasket with water in the oil. After pulling the pan and head, the inside looks pristine. The engine has 92,00 original miles on it. The oil doesn't have much water in it. The color is dark grayish brown and very opaque. Evidently the engine was not run very long with the emulsion of oil and water. My question is if the head gasket is not leaking, where did the water come from? The only place in the head gasket that looked bad was up front where it overlaps the front cover. This is the original engine out of the 260 & I'd like to use it. I'd appreciate any and all ideas that you ma…

Can someone help me? I need head bolts for my car. I see ARP bolts listed A12 and A14. What's the difference? The A12 is part no. 202-4202. The A14 is 202-4203. I've also seen to use 202-4206. I've searched and I tried to contact ARP by E-mail and phone with no luck. I have a F-54 block. Thank you, TimsZ

Hello, I am in the process of removing my Evap tank and reconfiguring the evap lines into the European style that doesn't have the expansion tank. My question is that I have a vacuum line coming from my manifold and carb advance into a metal distribution block and from there the line runs all the way into the back to the evap tank. What can I do with this line? Is it safe to disregard the metal distribution block and just run the line straight from the distributor to the manifold? Hopefully this picture gives an idea of what I'm talking about: Thanks, Han

Over the winter I'm working on giving the car a thorough tune up. Today's project was checking the timing chain to see if it has stretched at all. I got the car to TDC by using a ziptie in the #1 cylinder to feel when the piston came up then checked that against the mark on the crankshaft pulley. I then tried looking through the camshaft sprocket to look for those V and _ marks the haynes manual mentions. If I look behind the camshaft sprocket and down at the camshaft locate plate I can see the _ groove but I don't see a V indentation anywhere. I noticed my sprocket has three holes which differed from the 4 holes the one in the manual had.. so I checked ebay and found …

In the book How to modify your nissan/datsun engine, it says to apply anti-seize to front cover gaskets and to front cover portion of the head gasket. It also says to coat block side of the oil pan gasket with anti-seize. The other side with weather adhesive. What is the anti-seize compound? Is it the same you put on threads? I was going to use permatex for water pump, thermostat. Hylomar, etc. for flat surfaces. Thank you.

Hey mates For the past few weeks I've noticed that on acceleration in first from a dead stop (and only in first) I get a horrible vibration which vibrates, well, pretty much the whole car. It feels as if something is loose or not grabbing. Any ideas? Clutch? Engine mounts? Jan

Hi folks- This is my first post here. By way of introduction, I am not new to forums and I'm also not new to working on cars. Although I will say that working on gasoline engines is not really my strong suit; I'm a bit more familiar with diesels. I owned a 1971 240Z in my 20's, and I bought another one about a year and a half ago. I bought this Z in southern California and drove it home to northern New Mexico. The car is in decent condition, although it took a lot of tinkering to get it back here.... new plugs and a few filters along the way... but it did make it. It's been basically sitting for the last year and a half. I drive it every once in a while just to keep …

I am having a problem with oil seeping out in spots between my head and block. At first it was very minimal and now it is more noticeable. I am debating on replacing the head gasket as the possible cause. My question is what is meant by stage 1 and stage 2 bolts in relation to the head cylinder bolts? What is the correct torque on the cylinder head bolts? My head is an E88 head and is bone stock. The previous owner who I called up recently said he replaced the head gasket when he reassembled the engine. He had a ring job and valve job done while apart. The car from what I can tell uses no oil, antifreeze, or has no drips anywhere except for the oil seeping between…

Ideas ? I have a 72 240z, w/ stock n42 engine/block elct. ign., headers and su carbs. the compression is about 150 across, hot, there is a small oil leak at the head above #3 cylinder but runs good. I also have a f54 block with flat tops bored .20 over newly rebuilt 10:1 comp. with coated headers and rebuilt sus carbs, everything new dist, water/oil pump, etc. Question ... HP gains would it be worth the engine swap ? lets say hypothetically that I could sell my new set up for $1500-2000 range would the money be better spent with a head gasket and triples ? with dished pistons in the old n42? would like to go turbo but am scared of the money pit and complications I …
