^ That looks like so much fun to build. I'm 5 years too late for it though; my local junk yard cleared out all the cars with those parts.
Out of the CIS flapper back to the turbo. Turbo outlet actually comes forward to the intercooler (mounted next to the radiator) on the underside of the car, then into the ITB plenum from the IC. Tube from the plenum to the turbo inlet pipe is for the bypass valve.Originally Posted by tolusina
Don't rule out the older SAAB 900 WUR, fuel distributor, etc for possibilities to get everything running right. SAAB built turbo CIS injected cars from '78-84 before switching to the LH-Jetronic injection. Still along the lines of getting harder to find in the 'yard, but much the same stuff as the Volvos used. Even up to the early '90s SAAB used a T3 style turbo. Early ones were oil/air cooled Garrett T3 units, later ones were Mitsubishi built T3 sized with water cooled bearing sections. These also use an internal wastegate which makes the packaging nice.
As for turbo (and modified non-turbo) manifolds cracking, be sure to use some sort of support bracket. That's a lot of weight hanging out there!
Look at it this way....BAE and Callaway were turboing CIS VW's 30+ years ago. It's not new, it's no great shakes, and those old skool kits were un-intercooled and running primitive microfuelers.
I know a way to control the CIS pump via a piggyback system to fire the fifth injector when needed as well.
Some old skool goodness from 1979 and up:
And carbs+turbo=suck. Ask any Maserati Biturbo owner.
"Zed's dead, baby, Zed's dead."
My opinion is that Callaway and others were designed as bolt-on kits and it is totally understandable why they would devise a piggyback system.
There was enough knowledge of various CIS at the time that they would have known to use the volvo FD and WUR if they wanted to produce higher power levels that say stage 2 Callaway. You can take for example the Koenig TT kit for Ferrari 512BBi, AMG TT kit for 500 SEC, etc.. all CIS and no microfueller or other PIC setup. I believe that Callaway just chose this as the best compromise at the time for the VW kit.
As well, where do you get off with telling us it's not new it's no great shakes? Is it perhaps you that thinks you're the only one who ever saw a picture of a Callaway kit?
We are a bunch of ppl on here discussing how to turbo a car that was last produced with CIS in 1989 and how to turbo these cars with 1989 technology. And on a budget; this is what is great shakes.
Buying a kit out of a box and bolting it on is not really an achievement in my opinion. Doing it yourself is unfortunately more complicated but gives your a better sense of accomplishement. I feel even better knowing that my build puts down more hp than any of those kits did in the day using the same technology.
Anyways, if I had a Callaway or BAE or Janspeed kit in the first place, I wouldn't be writing this thread
So essentially, all I can say about whatever it was you posted before is:
[QUOTE=s2kvondeutschland;75223136]Dude... what? Seriously?
I didn't post the Callaway system, I merely commented on why it was so cool. And especially in the EARLY 80's.
Why are you then answering the question I asked the guy about the fifth injector and giving lectures on here about mixing and matching parts.
This post was started because somebody wanted advice about CIS turbo, not a historical discussion of the callaway kits, There are many other posts about that so pls don't pollute this post, much appreciated
As I plan on posting the tuning part soon and ppl appreaciate not having to sift though garbage and unrelated post when searching for info.
Now I'm confused, what is the system you have? Is it something to control a 5th injector or is it a programmable WUR like UTCIS?
Could you please tell us so that we have to stop guessing?
Did you try this yourself or is it speculation? Are you or someone else selling those if yes how much?
It would be great to have more precise, custom fuel maps with CIS if it's relatively affordable
What the subject of the post again? Was it Turbo on a 87 CIS cabby?, or the sit in basement and look for hours to find g*y a** pictures to post on the Turbo on a 87 CIS cabby? post
The only issue I have with UTCIS-V is the price, last I checked, it was something like $699. That's what all my turbo setup cost me.
Sounds like a great product from what I read on the Porsche forums but just a little too rich for me
wow......this is one strange how-to/info thread......
and as far as i thought THIS WAS about sourcing parts and building the most efficient and inexpensive turbo setup.
and if done right, which is possible and is far more rewarding than buying some kit, nostalgic or not.......ive done a turbo build on a non turbo car with sourced parts, and i had a great time doing it, a better time driving it, and a hell of a lot more pride in what i'd done....
with that said.....i think we need a car list to find parts from, turbos, cis distributors, piping, intakes......ect....the search if half the fun....
as i think i may have found a cheap turbo/mani combo to start this project......
i havent installed my header yet, been trying to decide weather or not to go turbo, and if i can get this turbo stuff.....that makes up my mind......
id only need a few other things to do this after that....
oil return bung welded.....ect...
I love reading about turboing these cars. CIS is the shizznit and I think it would be an amazing system to have with a turbo setup. I love the lack of serious electronics and computers and BS. There is a simplicity to it that follows just a few steps behind diesel to me. Love love love. If it weren't for my current dual downpipe setup and JH/ABA plans, I would have started working on a turbo setup from the start.
I have most of the fueling parts saved up but I would have to wait until I have the appropriate fuel pressure tools for a precise tune and I would love to hold off until I can fab my own manifold. I just keep studying until I get a good welding setup or my N/A ABA starts to feel slow
