Engine Projects for 2003...
 

Okay, let me know what your engine projects are for 2003. I'd like to hear what everyone is planning on doing (rebuild / transplant, supercharge, etc.)

-Wayne

I'm planning on a rebuild. It wont be until December, unless something bad happens sooner or I just can’t wait. SSI exchangers w/ new muffler, 20/21 cams, haven't decided on P&C's yet. Don't know if a c/r increase is worth it on my, so far, 100% streetcar. Waiting for the rebuild book to be done before I decide everything.

I'm in progress of doing the CIS-to-EFI project using the megasquirt ECU. Should be complete before spring time.

I'm also in the process of collecting all the pieces for turbocharging. I have the backdated exhaust that will feed a single turbo.

650 RWHP By the End of the year

Rebuild the engine in my 73 914. Needs a NEW case put around my good parts. Big Hole...........:(

Still toying with the idea of 3.4 with 10.5:1, twin plug, work heads, extrude hone intake - already have the good exhaust, mass air upgrade, etc. Objective is 300 HP. Then fiberglass rear bumper to loose an extra few pounds to enhance the power increase.

But I really need the final copy of Wayne's Engine book (with color pictures) to complete the spec list!

Late next year I intend to start my R'ring project, the motor part is looking like a 2.5 liter shortstroke. Twin Plug, weber carbs SSI Dual in/out muffler. This from a current 2.2T motor. So JE high compression pistons, 2.7 Cylinders, a Mag 7R case normal rebuild stuff.

With some more research I should be deciding soon to either add a turbo or do a 3.6 transplant. I know the costs of a 3.6, starting to look into the turbo route....:confused:

If I go the 3.6 route i will have a very nice 3.0 euro with SSI's for sale which has all sorts of new parts including a new and apparently hard to find euro fuel distributor...

If I go the turbo route i think i will have to sell the SSI's and rebuild the 3.0 in preparation for a turbo. The turbo route to me seems more interesting...

I could snap and sell the SC and buy a 993 and start all over! :D

3.6 conversion in my 2325 lb. 78SC. The front oil cooler in the MA Shaw Yellow Bird valance will go in in the next 2 weeks. I haven't chosen a motor yet, but I've been accumulating the conversion parts and other items to change with the motor out. I am hoping to do a 2 day swap - drive into the garage on Friday night and drive out Monday morning to go to work.

Ryan - you have to go with the 3.2 jugs and pistons as long as you are rebuilding!

Okay, time to learn. Tell me (and everyone else) about this MegaSquirt thing? I read the home page the other day, but it wasn't 100% clear? This is an open-source system that someone designed using off-the-shelf components (like the Linux of the EFI world) to replace troublesome fuel injection systems (like CIS?)...

More info please...

I plan to fix some oil leaks. I am going to build SS heatexchangers and install a G50 tranny. Maybe upgrade the turbo to a K27. I hope to have it all done by spring.

I'm planning on looking for a 2.4 crank for my 2.2 T case, installing E p&c'S and E cams with an MFI setup for my early P. I need all these bits so I'll be posting some WTB posts. I'm armed with the engine book so apsrt from the parts I'm all set

I would like to rebuild, might not be until O4' Mine is a 78sc motor in a 73T body

Like this:
used 9.3 PCs from a newer 3.0, 3.2 or...
have my Cs replated and after market pistons
hotter cams, probably a regrind
have the crank checked
re bush the Con rods
used carbs
aluminum pressure plate.
re curve the distributor if necessary/possible
new oil pump
pressure fed tensioners
heads rebuilt at the place you used with stainless valves


the normal budget rebuild!!

This is an area I’m still very unsure about and I bet Wayne’s book would take care of my ignorance here.

I thought that the SC heads would not seal to Carrera Cylinders. No grove for the sealing ring I believe. Is there a way around this or do I need new heads too? $$$ Ouch!

Also, I have never met anyone that has actually done 20/21 Cams AND 3.2 P&Cs. I’ve met guys that have done one or the other and the guys that have done the Cams have been the happiest w/ it. Actually I’ve only met one guy w/ the short stroke 3.2 and he said he felt like he needed to be at 5000 rpm all the time to stay in the power. Anyone else have experience w/ this?

I would love to talk to someone who has personal experience w/ both mods on their engine.

Read my other thread on detonation before you start to mess with stock 3.2 engines...

The 3.2 and SC heads are nearly identical - just the ports, and the size of the intake runner mounts are different. The way they mount to the cylinders is the same...

-Wayne

since I am in Germany for a few years, I have decided to concentrate on the heart of the car, engine and suspension. I have decided to go with a 3.6 (993) transplant...this project will start NLT Feb, and the second part of the project will follow into the summer and will include new shocks all the way around with beefed up components where needed.

While I don't have an engine-project planned, my New Year's Resolution is to build up a 915 with "Airport Gears" or something close and low-ratio for the 2.7 to give it some extra punch.

I also have an engine to rebuild, in my Carrera 3.0. I will probably go with 3.2 P&Cs and 964 cams, along with a 930 oil pump, dowel pinning the cases, lightening and balancing the lot. Not before fall, though, as professional commitments will prevent any serious work for 2003.

Hey Wayne, if you want to learn about the MegaSquirt all you need to do is read your other forums. :)http://forums.pelicanparts.com/showthread.php?s=&threadid=90992&highlight=megasqu irt

I hope most of my "Engine Project" will be finished soon after '03 rolls in.
Then, I intend to drive, drive, drive!

Tensioner upgrade for sure (shooting for doing it at 50K miles). You going to have another "ragin' deal" on tensioners in the near future Wayne? Beyond that, it depends on my mood and budget.

Complete rebuild for me....mostly to stop all oil leaks.
I figure as long as I'm going to drop the beast...why not do it right? (Darn you Doug!) LOL
Have been toying with several ideas for modification...O-ringing everything (to get rid of leaking gaskets)....maybe a gear drive for the cams...definately a coil on plug ignition....maybe a different type of injection system.
Over-all idea is to clean up the engine...both visually and oil-wise.

Re: Engine Projects for 2003...
 

I going to change the oil twice and drive the PI$$ out of it whenever I can.

Jrdavid68
1986 Carrera
170,000 Miles

I'm in...

3.0L SC base
Mahle RSR pistons and cylinders at about 10:1
Twin plugging
Open heads up for more flow (to near RSR spec)
Valve job
Titanium Valve springs and retainers
Semi-aggressive CAM (staying within 4200-7200 RPM power band)
Complete rebuild to bottom end
(Using Weber 46's, equal length headers and some sort of open exhaust)
Stock 915 gearbox (for now)

Intend to complete by April

Install oil cooler and fan- believe it or not- current car has no oil cooler :O -as it was a standard 'T'.
Engine does not seemto pass 210F at the mo. as I have only driven it past 3 months and spirited for short bursts!.
Also try and squeeze some more rubber under those narrow fenders! otherwise may have to go for the SC/RS flares- no tail tho!
Lastly to resolve oil leaks :(

Upgrade in 2003-
 

I plan on buying a used 2.7 or 3.0 to rebuild myself and then install in my '69 as an upgrade to my stock 2.0 liter.

Wayne's book will be a must for me soon.

I bought engine management for my '69, I'll use it to fire the plugs for now. I plan on buying TWM throttle bodies, and making a sequentially injected, twin plugged 2.2 race motor. The base 2.2 motor is solid as a rock, previously I built the bottom end with a cross drilled crank, a modified main bearing. installed a 930 oil pump, shuffle pins, oil by pass mod, etc.


More importantly is finishing the car for this years race season.... Im hoping the car is between 1750 and 1800 lbs, and Im going on a diet too
:p

Oh yea Megasquirt is like the Heathkit electronics kits you could buy to build a stereo etc ( years ago)... the will sell you a circuit borad and instructions...... with some software support as well....

cary is your 2.0 a six or four? I have a 2.0E longblock if you're looking.

Rick,
I may have a good 2.7 for you this spring? You would just need the exhaust for it...you know it runs like a scalded raped ape!

I need to complete the 3.2 swap into my '73. Engine is sitting on it's new SSIs, Tranny is complete w/ quaife, wiring still needs some work to complete, and I need to finish hanging the rear suspension prior to engine install. It's been sitting for months now, time to finish it before spring.

K-9 Guy-
 

You are right Smitty, after driving your car, I realized that a 2.7 will satisfy my needs!
Let's talk and figure out what we might be able to do.

2.5 short stroke, 7R case, oil bypass modification, sc oil pump, reconditioned rods, mahle rsr pistons/clyinders, E spec cams and mfi, throttle bodies just back from Eurometrix. Machine work is done, just need to pay for those pistons and cylinders!

I have a 2.7 that I have (at least at this time) decided NOT to put in my 914. I have been looking at various early cars with the intent of building a retro engine, i.e., strip off the CIS and install carbs. Or, if I'm real lucky and find a car with MFI, I might try to move it over to the 2.7. Waiting for Wayne's book to verify that I will want to change the cams and install P/Cs to fully augment the carbs. Finished off with a street header system, this should be a fun car. I honestly don't care how much power it makes as long as it runs perfectly. I'd rather have 170 HP than a poorly set up and tuned motor with 225 potential that it never sees.

headwork; Quaife; monoballs and Chuck Moreland's strut tower brace. Then, I'd be almost "done" with the medium to large projects (if it's even conceivable to be "done"!) until the motor comes apart totally.

'03 Plans
 

My list:

#1 Pray to the Porsche Gods that my motor doesn't give out this year. Assumed a rebuild or transplant winter 2004 when I bought it this fall. '83 SC currently has 165k. I expect to put on around 5-7k miles a year.

#2 Learn as much as I can about working the motor. Read everything I can get my hands on and vistit NoVA foks who are doing engine projects to get more hands on.

#3 Learn to tune the engine to maximize performance. Buy tools to set correct mixture adjustment. Set timing for idle and 6,000 RPM (buy adjustable light). Valve adjustment & major tune up.

#4 Figure out O2 system and decide if I'm keeping it or scrapping it. Think it's currently broke.

#5 Fix oil leaks.

#6 Go to Mobile 1 synthetic with oil change.

#7 Lurk around waiting for opportunity to buy a 3.6 at a crazy low price.

I have a 3.2 swap in progress right now and should be done in about 2-3 wks. I came into a sweetheart deal on a 3.2 with 8k miles on the rebuild and all kinds of upgrades. It worked out to be a lot cheaper than rebuilding my smoky 3.2. Sway-Away spring plates are going in when the engine is out, then she goes in for an alignment and then she's ALL DONE!

I'm building my 2.4L hotrod motor; I'm planning on offering the engine as the subject of an engine building clinic to be taught by "zuffenhausen" and his dad. I'll just be a wrench-turning peon.

Recap- 2.4L, GE60 cams, 10.3:1, case updates, massaged heads, sport exhaust, Webers.

Then I've got a stock 2.4T MFI engine in pieces in boxes in my garage. I hope to drop off the parts for that at the machine shop in the next few weeks. The rebuild should commence by summertime, as it is much less complicated than the hotrod motor.
