Official Sasquatch build thread Part 1, Cosmo Rotary Turbo... Then boom... Options

[Mike Bellis]

I don't know the exact CFM. I can tell you the engine consumes as much air as a 2.6L engine. Sometimes more. I would be happy if the engine runs cooler than normal as the rotary engines run hotter normal temps than most. This type of engine really benefits from lack of back pressure, especially with a turbo. Most RX7 guys run 3 inch or larger to get 500+hp. I will restrict it if needed.

You are certainly BIG on the exhaust, Especially with no muffler... But I dont think your going to run into any issues with that kinda setup..

[banksyinoz]

its great to see such a nice rotor setup in a 914, i look forward to seeing the end result.

has the fuel rail, regulator and pump been upgraded or modified also?

Not yet but it's on the long list of crap to finish this project. Right now my problem is money. Since I was out of work for a month, all the bills got behind. Still playing catch up.

Ive been mostly working on the cooling system. I'm also rigging some NACA ducts for a cold air intake and cooling air for my water/air intercooler. Since my car is soooooooo far from stock, I'm not too concerned with cutting the body.

If you are a purest, don't read this thread... Maybe I should have put that comment in the first post???

What a great build, you have some skills man.

I think the rotary is a perfect fit for a light car like a 914 and I want to do one sometime.

I love the sound of a rotary more than anything else except maybe a Ferrari V12,
which is probably too long for a 914 and I hear their parts are hard to get (IMG:style_emoticons/default/evilgrin.gif)

In 1970, Mazda teamed up with Belgium Racing to put a rotary engine into a
Chevron B16, which was a very light English, prototype race car. The rotary
in the car was so loud it made the plaster fall off the Chevron shop ceiling.

The car raced at Spa 1000km (15th overall), Nurburgring 1000km (10th overall
and second in class), and Le Mans (retired after an hour with carb problems).
This was the first rotary car ever to compete at Le Mans.

So anyhoo, there is a long history of rotarizing light sports cars. Let the pinky
benders eat your exhaust!

Thanks, I owe my training to my Dad and working in his Gas Station when I was a kid.

I'm wondering how well received this will be by my felow PCA members. I think they liked it with the V8 after they saw me keep up with a Turbo 911...

[Mike Bellis]

I found some California rust today. Mostly dirt and red primer but there is a pin hole in the jack post support. I wire brushed it, welded the rosettes on the stiffening kit and coated it with some primer. Call it good for now.

[Mike Bellis]

Here's another picture of my sway bar mount. I was thinking of buying Engman stiffening parts but I have scrap 14ga steel and I will cut my own. That will save my $60 since I'm a CSOB 914 owner...



Here's my CSOB piece. view of the back...

[Mike Bellis]

A little welding, grinding and primer...



I traced the pattern to weld onto the passenger side later...

I have also been working on the oil cooler system. I have the largest oil cooler I've ever seen and it connects with -12 AN fittings. I bought some nylon braided hose because it's lighter and it will not poke you under your finger nails. If you have ever made braided hoses you know what I'm talikng about. I ordered 20 feet. I hade almost enough. I need a 1 foot piece with a 90 and straight fitting and I'll be complete. I installed Tee fittings in the front and rear. The front is to bleed air out. The rear is for my future oil accumulator. I ran the lines down the outer long, under the rocker.

[Mike Bellis]

Been too long since an update. I tore my tranny apart at the Dr Evil clinic. Not all the way because the tranny was just fine. I had the Dr inspect my syncros and re-align the forks. I also changed all the seals and swapped the tail housing.

Working with the guy at SPEC Clutches (former 914 owner) and bought a Stage 3+ clutch. Should hold more torque than I have to provide and the + part is a streetable disc to go with it. I also comes with a NEW throwout bearing and tool.

This weekend I will tackle the exhaust and some "little things". Those things that get forgotten until the end of a project. If my AN stuff from Summit shows up, I will finish the fuel system too.

Here's some pics just for fun... (IMG:style_emoticons/default/biggrin.gif)

I have been getting my braided lines from www.aeroquip.cc You should check them out, awesome prices.

I've used them and others. Summit usually has Aeroquip within a dollar or two of that site. I use Summit mostly because they ship from Reno and I have my delivery in 2 days ground. Save a lot on shipping. Most of my -12 is Areoquip while the other ones and smaller are Summit brand. The quality is just as good and the prices are much cheaper. Never had a leak or broken fitting.

[Mike Bellis]

Update. I worked 12 hours toady and got a lot done. My exhaust is done! I tied the wastegate into the exhaust. I paid close attention to the direction of the exhaust spiral down the main pipe. I tied in the WG so it will not disrupt the spiral and will flow better into the stream. I still need to cut the tip of the exhaust back a little but I want to see how it looks for a couple of days before the final cut.

[Mike Bellis]

Money shot!



I used a stock muffler bracket and gusseted it to hold the muffler, which is large! but light weight...

[Mike Bellis]

Got my fuel lines and oil lines complete. I tied into my perviously installed aluminum hard lines...

[Mike Bellis]

I started mocking up the mount for my Air/Water intercooler but ran out of welding wire (IMG:style_emoticons/default/sad.gif)

Much of my time was spent tightening bolts, changing gaskets, connecting hoses and the crap that I will forget to do later. Most everything was put in hand tight for fab purposes...

[Mike Bellis]

I also started fabbing my shift linkage. The main rod was done when I got the engine installed. The front rod/shifter was done back when it have a V8. Here you can see my bracket and dual bushings. J West makes much better looking stuff but this is my getto trailer park CSOB version. It works the same...

When I get more welding rod I will complete the fab...

[Mike Bellis]

I think HD sells mig welders. I will go tomorrow and see if the have some .030 wire. I'm exhausted! time for an ice cold beer! (IMG:style_emoticons/default/beer3.gif)

[geniusanthony]

My local HD doesn't sell MIG wire, I have to go to Lowes for metal supplies...Your's may be the same.
