Starting on the turbo project. I am starting to believe this 4 speed car has the original turbo even though it is a silver one. There is an original owner 62 Jetfire north of me that still has its original turbo and is silver. I have not seen them but he claims to have original pictures of it when it was new to prove it. The time between his turbo date and car build date is the same as mine. Even if mine is original, I am going to use this red turbo on my car because I like the look of the red better. This turbo was apart before but everything inside looks great. Even the controller diaphragms are in great condition. It for sure has to have a seal but other than that I am pleased.March 15, 2017 at 8:20 pm #12658johnsageParticipant
I bought one new in Oct. 1962 and it had the silver turbo. I have owned two others since that also had silver turbos. I have two now but I don’t know what came on them originally, although I have reason to believe one of them came with a red turbo.March 29, 2017 at 4:24 pm #12681
A couple weeks back I was able to get the spark plugs out. I feel so much better that I don’t have to pull the heads. I had oiled them nearly every time I had the engine hot last summer and fall. I was able to get them to turn about a 1/4 turn and soaked them again and the next day they came out. They were tight but did not hurt the threads in the heads.
Before I pull the turbo that is on the car I wanted to boost with it and see how it would do. This turbo’s seal does not leak surprisingly. I rebuilt the fluid valve last weekend and installed a rebuilt Check and relief valve that Jim crimped back together back in late 2015. I put the old 13″ radials and wheels on it from the automatic car and took it for a drive tonight. This turbo boosts great! I drove the car for the first time at cruising speeds and even up to 60 MPH one time. I boosted probably 10 times and the car performs great! Jim,, you were right about the stock shifter, IT SUCKS….May 8, 2017 at 3:41 pm #12739
I have been looking for an NOS washer jar since 2011 and finely found one. I am sure some of you seen this one on eBay but it was way over priced. He lowered his price and added a best offer after a couple weeks. I shot him an offer and he took it! I will likely put this one on the automatic car and that one on this 4 speed car. I get as excited finding NOS parts as I use to when I was riding FMX on the 4 wheelers, lol.August 26, 2017 at 7:03 pm #13025
With all the over time I am working the red turbo project is still on hold. Today I was able to get some time away from work and with the limited time I had I decided to pull the tank out of this car. The trunk pan is still very nice above the tank. The car has lots of surface rust on the bottom but thankfully everything is solid still. The biggest issue is the roll pan on the back. It will need replaced but thankfully I have an NOS one now. The tank is full of junk and some rust particles. The tank don’t have any holes in it but I will have to clean it out real good. I am undecided if i will add a liner to the inside but I likely should. The bottom inside of the tank is good but the rusty area is the top inside where the fuel was not covering it.August 27, 2017 at 2:19 pm #13031
Turns out that the seam on the tank has some bad spots in it. I believe a liner will fix it but for now I just cleaned it out and put it back in the car. I will just keep about 5 gallons in it to keep it below the seam. I will not drive it other than pulling it in and out of the garage. I will decide later what I will do with it. I have a Buick tank that is nearly identical. I can likely swap the neck and move the vent and work just like the original.July 3, 2018 at 8:18 pm #13822
I am reverting back to this thread since we are not restoring this car for another year or so.
I took it out for a drive and a little testing tonight. I wanted to see where it boosted at and what the vacuum readings were on it. I pulled the boost gauge and installed an accurate vacuum and pressure gauge. at idle it has a 20 inch vacuum. I did not think it would be that high. When cruising steady at 55 MPH on flat ground it was at 17 inch vacuum. I done two full pulls and both times it went to 8.5 PSI. I assumed that my gauge was off the first time so I did it again and it went to the same place. I got home and tested my vacuum and pressure gauge and is on the nose correct. I then tested my fluid tank cap because I thought it would pop before that but it pops at 9 psi.
I then tested my boost gauge and it is at 20 inch vacuum and 8 psi at each extreme of the needle.
I am fore sure surprised that it boosts this high. I feel sure that this turbo has never been apart or modified. I did this with our automatic car and can’t remember what the figures were. I am going to do that car soon but it does not have the original cam in it so the vacuum readings will likely be different.July 12, 2018 at 11:49 am #1384162oldsf85Participant
This is a kickass post, Eric. Just read through it this morning. I’ve been off this site for a while – I get super busy and time slips away – but just had a 2nd rebuild on my engine, though this one was more of an overhaul. My internal sound turned out to valve guides – it sounds like a sewing machine now. I’ll post some pictures soon. Gotta have the red turbo, Jim just did mine and it’s terrific. I run a boost gauge and I think I get about 6-7 pounds of boost, but as the gauge isn’t digital, it’s a little hard to tell. I’d be really interested to talk with you more in depth. Are you coming the Gettysburg nationals? We’ll be there. By the way, my son gets Hot Rod and we saw their feature on your car. We were psyched for you. You’re right about these engines, people swarm around them and it’s fun to see them do a double take on the turbo.July 12, 2018 at 12:15 pm #13842
I feel like I should know your name but can’t place who you are by your user name. Unfortunately we will not make it to the nationals this year. We will be at the Homecoming show in 2019 with both of our Jetfire. They will be hosting the Jetfire for next years show. Feel free to call me anytime. 812 nine eight six three three six five.
When I restore the car it will have a red turbo on it. I may put a red turbo on it for the homecoming show but not sure yet. I have one I started building a year ago and got pulled off the project and never got back to it. I plan to finish it later this summer so it may find its way onto this car for Homecoming.July 13, 2018 at 10:13 am #1384762oldsf85Participant
Scott Philliips in VA. Joe P and I live near one another and belong to the Capitol City Rockets Olds club. The pictures on the site of my car are pretty old. I should send some updated ones. I’ve got the Sports Convertible with the Jetfire engine. Attached are a couple of pics. I’ll call sometime. I am definitely planning on going to the Homecoming with mine next year. That should be cool.
