73str86 Posted February 13, 2017 Author Share #73 Posted February 13, 2017 A dead fuel pump left me stranded one day. Surprisingly I was able to limp home. With 2 day shipping from Amazon, she's back on the road. Link to comment Share on other sites More sharing options...
JSM Posted February 14, 2017 Share #74 Posted February 14, 2017 I might have posted in another thread of yours but what model/part# Borla did you go with? Link to comment Share on other sites More sharing options...
Captain Obvious Posted February 14, 2017 Share #75 Posted February 14, 2017 Beautiful. I've always loved the look of those headlight covers. The Grow Warehouse - Hydroponics and Organics - In Colorado. Owned by Cheech and Chong? Link to comment Share on other sites More sharing options...
73str86 Posted March 1, 2017 Author Share #76 Posted March 1, 2017 (edited) Some updates: - I have another failing mechanical fuel pump. $16 cast unit from Amazon. - I picked up a two owner early 260z from NM to resell (yellow). She was purring like a kitten within an hour of getting home. - I stumbled upon a "rust free" 72 two owner California car (white). Cleanest underside I've ever seen. My 73 may go back to stock and be sold in order to keep this one. Edited March 1, 2017 by 73str86 Update Link to comment Share on other sites More sharing options...

Not a big following here. Most bodies are very clean or very ratty, one or the other. Link to comment Share on other sites More sharing options...
73str86 Posted March 27, 2017 Author Share #79 Posted March 27, 2017 (edited) I've been chasing a fuel starvation problem both at starting and WOT. I suspect it's vapor lock a result of 80 degree temps at altitude. It's time to put some heat resistant tape back on the fuel rail.

SteveJ Posted March 27, 2017 Share #80 Posted March 27, 2017 I've been chasing a fuel starvation myself at WOT. It showed up before my engine swap, but I was able to make the carburetors richer to compensate. Now that I have a 2.8 with higher compression, I have the SUs as rich as I can reasonably make them. My fuel pressure is low, though. You may want to check fuel pressure to verify whether or not that could be contributing to your problem. 1 Link to comment Share on other sites More sharing options...
73str86 Posted April 17, 2017 Author Share #81 Posted April 17, 2017 I do now believe it is vapor lock due to the elevation and recent temps in the high seventies. I triple wrapped my factory fuel rail with Thermo-Tec this morning and switched spark plugs to match my E12-80 dizzy. My recent plugs were a perfect brown shade. I was very happy with their appearance. I decided to take her up Pikes Peak last week. What a blast. The 15,000+ foot summit was closed due to weather, but I made it up to around 13,500 feet. I hope you enjoy the photos. I am very excited to be getting a baseline dyno tune for my engine this week. $80 for three runs. My plan is go with run 1 as-is. On run 2 I'd like to crank up the timing and see the results. And following that I'm considering turning the mixture nuts an extra 1/2 to 1 full turn richer for the 3rd run to see if she wants more fuel. Thoughts? 1 Link to comment Share on other sites More sharing options...

73str86 Posted April 17, 2017 Author Share #84 Posted April 17, 2017 My only work to be done before the dyno session is to replace some heater hose bypass caps that are starting to show their age. Unless you folks have any other recommendations? WORK TO BE DONE IN THE NEXT COUPLE MONTHS: Install retro-spec type 1 air dam Install Les' 432 rear spoiler Rebuild/refinish NISMO 44s Electric fuel pump install Seats?
