Sounds great, btw you said turbo volvos had a boost referenced fuel distributor, not the case...

Kjet is easy if you understand it but i admit there is a slight learning curve. Expecially these days with such easy access to info on the internet, just not as many people mess with it anymore to help you out. Learned that the hard way and just taught myself with the old volvo greenbooks..:my car ran TERRIBLE when i got it. Runs like a bat out of hell now i know how to twiddle her "knobs" properly.

Go here and scroll down to the "Turbocharging with CIS" portion of the page; it will give you a list of parts to build your K-jet turbo.

I watched his posts over time and he fixed and fine tuned everything you could possibly encounter whipping up a CIS turbo car.

I meant WUR and typed fuel distributor. I brought two E21's back to life. The CIS K-jet is great, it's very adaptable and does a great job of metering fuel once the system is sorted. The issues are sorting an almost 40yo system requires going through every single subsystem because 9 times out of 10 the fuel tanks are rusty and that plays havoc with every single thing in a CIS injected car.

Sorry. I meant ridiculously powerful for a car thrown together in a weekend from spare parts. This was before there were any local dynos and megasquirt was still just an open source circuit board and parts list that you had to order from a group email list.

This was a long time ago. The car was daily driven for over a decade after. It was fast though.

Whose was it? I'm curious.

I lived with the stock 90hp or whatever for close to 100,000mi. I still think that the limits of K-jet will preclude the car from ever being "fast" Although, as much as I feel duty-bound to finish the low compression 2.3 10v project that I bought/inherited, I am being drawn more and more to the dark side: 07K. 700hp might be enough to be entertaining for a car that big.

If you guys could keep an eye out for one of those Volvo parts, I'd be mighty appreciative. Those things were crushed/parted through these parts long ago.

A few thoughts on the non-motor side of the project.

I have a '79 that I had up to about 120hp at the crank using Weber 32/36 for a few years, and now I have it up to about 160hp N.A. at the crank using Motronic 1.3. But that's with a 6-cyl block.

I track it fairly often. This weekend, my instructor was a woman who started out tracking a 320i in 1979. She turbo'd hers after the first couple years, and said it was an improvement, because it finally gave her a little throttle-steer capability.

When I went from 120 to 160, the extra power was pretty much useless because of the open differential. I eventually found an LSD for it, but it wasn't easy or cheap. Also, 160 may be plain old too much for the rear end, because I have already broken one diff cover. So, I now try to keep at least one cover in the track spares.

On the one hand, the car is a real handful on the track. It doesn't transition from one attitude to the next at all gracefully; I need to be smooth and plan my moves in advance. Its main goal in life is to oversteer. If I am braking heavily, I better have the car on a straight line. If I am lifting off the throttle, I better have the car in a straight line.

Example: There was a new-ish instructor at skid pad this weekend. We went out and he gave me a 3.5, which is a pretty good score. Then I let him take the car out and try to manage the oversteer. He spun repeatedly. Then he went back and gave me a higher score.

On the other hand, that oversteer is a useful track tool for me now that I know how to use it. And the car really has no pity for any driver error, so I have improved my track skills in less time than I would in, say, my E92 M3.

On the third hand: brakes. Mine has 4 wheel disc brakes (yours doesn't). Hauling the car down from its front-straight top speed of, say, 99 mph takes all of my faith and my courage. It's a boundary limit to any additional high-speed development at this point.

The car is a blast to track. But pretty much any other BMW or Mini, with any other driver that has even two-thirds my skills, will eventually get a point-by from me.

Not to say it's a slow car. On a tight track like the Jefferson Circuit, my lap times are about 5 to 10 seconds slower than my lap times with my 420hp E92 M3. (I will try to post two session videos, one with each car, on youtube soon and post a link in this thread). But it's still slower than everybody else's toys these days, if it bothers you.

I'm pulling for you to turbo this car and make some noise! But if it were me, I wouldn't spend a whole lot extra to get more than 150hp or so, unless you want bragging rights. And hey, what's wrong with bragging rights?

I can agree whole heartedly with the braking issue, I have been looking into the e30 conversions for them, but it is somewhat hampered as I'm still permabanned on BF.c(for the last 7 years last I checked) Only my phone on mobile could get on there. As far as the handling traits, I'm not worried about it as I cut my teeth on a 318ti, snap oversteer is a challenging thing of beauty.

Yeah man!

I went back and looked at the Jefferson Circuit videos. The M3 is setup as a 1.2g car, with 420hp at the crank. That means the corners all happen 5 to 10 MPH faster, and the straight top speeds all happen 15 to 20 MPH faster. That adds up to about 10 seconds a lap faster. Lot of money for ten seconds a lap . . . but the difference at Watkins Glen would probably be in minutes.

What did you do on BF? Talk about slamming your suspension to the ground in the E21 forum?

There's a budget Volvo disc brake conversion for the E21 fronts, but I don't know anything about it.

Oh yeah, forgot to mention the E21 on the track shakes you like some astronaut training machine. Makes you feel like you're going one million miles an hour. Nothing like it, except maybe a bike.

Back in the era of 4cyl BMW bashing by M3 owners, one of the most prolific hate mongers was a mod with an e36 LTW....and kept saying my ti(DSP prepped) would never be able to beat him autoxing. So, I finally tracked him down at a localish bmwcca event, and proceeded to land FTD of said event by a large margin(3 seconds quicker than the rest, 6 seconds quicker than said Mod)

I was IP banned for making him eat crow on BF.c when I posted the results. It was a glorious day, and I love embarrassing people.

One thing I learned from years of K-jet Volvos. Those fuel distributors do not like to sit. Old gas gums them up, and all the king's horses and all the king's men can't ever get them clean.

Well, they can have 4,6,& 8.........but the US spec E36 M3 is NOT an M3.....it might as well be an M appearance & handling package. That's what made it hilarious.

Yours wasn't truly gummed up if gas made it from the tank to the fuel distributor. When they get really bad, the car won't run at all.

Okay, here's a link to my E21 on Jefferson Circuit.

No, the camera mount is not shaky. The car is really hammering around that hard. I'm pretty proud that I have gotten the old girl to be a 1.0g car, but the price has been stiffness.

She's capable of doing about 3-4 seconds better per lap. But this was the last session of the weekend, which is the only one that gets graded, and my instructor valued precision over all else. So I didn't take any chances.

I get passed TWICE by the 911 GT2 (I think it's a 996 but it might be a 997).

E21 at the track

For comparison, here is an E92 M3 at the same track with the same driver, several months back.

Which is what is up from my GRM-sourced GTI. The fuel distributor isn't doing much of anything useful.

Which kinda sucks because part of why I bought it is because, deep down, I like the way CIS just plain works when it hasn't been berked with. They're like Quadrajets that way.

In reply to Knurled:

Ive asked on a volvo forum how they clean their distributors, i can link the thread if youd like but basically pull it out, use a sacrificial low volume fuel pump and pump industrial vinegar or a heavy duty petrolium based cleaner through, keep the injector lines hooked up without the injectors and have them return the fluid back to the container (5g bucket) where the pump is drawing from. of couse have a big filter before the distributor. Let her run a few hours and it should be golden. Everyone said not to take it apart, but we all know how neglected 30 year old volvos can be so if it worked for them (and me) it can work for you too.

Op if your still looking for the volvo bits to make your stuff turboed id check the turbobricks forum, be careful not to stray or say anything other than in the want to buy/for sale section. Lots of retardation going on there. But theres plenty of old volvo parts to be had. Ps dont look on eBay for a used turbo warm up regulator or your wallet will hurt just thinking about it, when i was looking they were $400-$500 so i just adjusted and cleaned mine. Which is off a non turbo car yet works fine for turbo duty, wideband verified.
