Hello, I am in the final stages of assembling my car after extensive restoration and I'm kicking myself for not having bench bled my clutch parts. Anyway I have bled the clutch per the FSM, and using a pressure bleeder, the former with more success. I have fun about a half litre through the system now using the FSM method and when I crank over the car I can still feel the car move forward ever so slightly. Which is a massive improvement over how it would lurch forward initially. The slave is brand new Nissan as well, all new hoses, and clutch master. The car is also slightly more difficult to roll if the car is in gear and the clutch engaged than if it is simply in n…

Hey members, I currently rebuilding my n47 head and replacing the timing chain on my car. Before reinstalling I was thinking about installing a mild cam. I don't much about upgrading a cam, so I have a lot of questions. Do I need to upgrade springs or rockers. And is installing the same as a stock cam or Should I not bother?

Continuing to pull apart the '71, which has been modified by POs. Documentation obtained with the car indicated it had a 4.11 R180 differential installed. We replaced the U-Joints in the stock Half-Shafts, and pulled apart the differential today, only to find out it has 3.545 gearing. It also has a large "K" stamped on the top, which I understand is from the 84-88 200SX. So, someone has replaced the stock R180 with a later replacement R180, geared identically. I understand there's some work involved to get this to bolt up with stock halfshafts, so someone spent some time here. I guess I'll be looking for a 3.90 differential now, and will be doing the R200 swap. Not some…

Hi, I am going to be getting a new cam or a regrind, and rebuilding the whole head in general, so I had a question regarding finding the correct lash pad. I understand doing the wipe test etc., however in everything I've read it says to try lash pads until you find the right size. Since I don't have different sized lash pads lying around, and it would be a pain to order multiple lash pads and wait for them, is there a way to shim the original lash pad and find the correct size like that? and then just purchase the set of the size I need? I understand that it is recommended to check every single rocker, and each pad size may differ if the valve stems aren't aligned to the …

I have a 78z that the grinds when shifting from first to second and then from second to third. It works ok if I shift slow but if shift fast or high RPMs I get grinding. So I want to replace the transmission but not sure which one to go with. Should I go with the Nissan close ratio transmisson from 81 to 83 or the Borg Warner T5? I would appreciate any input.

I know that there are many posts on the topic of running lean and the fuel system. Just a quick note again to let everyone know that I am an extremely novice mechanic. I know that most of this stuff is in the FSM but when I read for the first time it might as well be in spanish. With a little help from this group and the FSM I can usually figure things out. So bare with me. I have had a little help in this area previously but could use a little refresher. I just recently completed dropping my tank and coating. Tank had some rust issues. Initial question, my car seems to idle best at 1000 rpms not 800. I have played around a little with the TPS. I know that the FS…

Hi guys, I'm new here and this is my first project (I'm learning as I go and have no background on mechanic or anything like that), so i probably going to have lot of questions. My first question is I got a 280z, and after I remove the value cover, I saw the engine as attached in the picture, and the inside of the value cover was dirty as well. I was wondering what's the best solution to clean it myself instead of sending it to someone else to do it (I'm trying to do everything by myself as much as possible).

I am running triple Webers being fed by the front outlet on a stock 240 fuel rail. The rear outlet currently sports a short stub of fuel line closed off by a bolt held in by a hose clamp. Yes, it works but it just seems a little ham-fisted. I'm looking for a feng shui solution here, guys. Can anyone think of a more elegant, non-destructive way to close off that unneeded outlet? Thanks!

Posted this over at hybrid too. Mostly a lot of snarky comments from ****head n chief Tony D. I had my P90 machine 15 thousandths but the head was warped more than that, so they heated and straightened it. They told me the cam spun fine, which it does to a certain degree. I have read that the cam should spin with 2 fingers about 360 degrees with minimal effort. With mine torqued to 12 ft lbs. it spins about 300 degrees but is tighter then this finger spin everyone talks about and for about 20% of the rotation it is even tighter. It never doesn't spin. I am convinced the shop did not machine the top of the block after all of this. I ran it over to another machine sh…

Hi, so I am about to embark on an engine rebuild and am planning to get a cam regrind. I have an l28 with an n47 head and roundtop su's. I have 2 questions. 1.) I heard the e88 and e33 heads had cams that were more suited to being reground, is this true? Is the n47 cam ok to get reground? 2.) Does anybody have experience with any cam grinders in the bay area? Or if not is delta cams good? Thanks!
