The next big thing....3.0 EFI/ITB w/Rasant engine management

[al lkosmal]

My latest 911 hot-rod, engine build project is underway.
I am building this engine for Andy Chapman in California.
Andy saw my 27 RS-ish engine and asked if i could build his 3.0 in a similar fashion.

https://www.youtube.com/watch?v=EWB99lddFew

After some discussion, regarding Andy’s ideas/driving style/requirements, we pinned down the following build specs for his 3.0.

Andy’s 3.0 build 9basic spec)
• S3-EFI/ITB kit (this is my EFI kit)
• 9.8:1 JEs
• E-cams (Well, like early E, but with more lift)
• Headers
• Sport muffler

Andy wanted to incorporate both, my S3-EFI/ITB kit....



...... and the new 911 engine Management kit from Rasant Products (by Andrew Darud)
Check out the details related to the rasant Products kit here:

911 Engine Management Kit

This kit looks to be a very well thought out and Andrew Darud and I have compared notes to ensure that it is configured for this engine build.

….so that is what is happening.

I will post the progress of this build from engine tear-down/rebuild to the fire up and tuning on my engine test stand. This will include the install of both kits…along with pix and commentary on how it all comes together.

So, that being said…….here’s the current status of the project.

The 3.0 engine was shipped to me and arrived in this handy 1976 911S carrying case…………



Since then...we've made some progress by dropping the engine out of the 76 and moving it to the stand.




I'm fairly far along with the tear down of this engine and it is in really excellent shape...........



I won't bore you all with the typical rebuild minutia...but ......I have boxes of new parts (P&Cs, cams, bearings, gaskets....etc.) headed my way...some are already here



I can't wait to open that box and when i do, i'll provide more detail regarding the capabilities, which features we will be incorporating into this build and my impressions of the system from install to tuning.........
I'm taking a few days R&R...but i'll get back into it and post progress next week.....and I cannot wait to fire this one up.

regards,
al

So is the "Rasant Products" kit an AEM Infinity ECU (great ecu) with a harness?

Is your throttle kit start with parts from a sport bike coupled with an adapter, fuel rail and mated to a Weber manifold? Pricing?

Cheers

Al, can't wait for the next installment. The skunkworks rides again.

And you really have to stop messing with me as you know I have a thing for 3 liters.

Rick,
This will be a stellar build. Stay tuned, i will update as I go and....everything that will be done during Andy's engine build can be applied to your 3.0 as well.
(but 1st.......maybe we can get your CIS working well.)

regards,
al

PS: see you Tuesday

Al, looks exciting. What TBs are those?

Andy, nice project. I like the P1800 as well.

I wish I still lived in Monterey. I don't believe we ever met. I drove two flat black 911. Maybe you've seen me?

Jesper,
Greetings. If you PM me with your email address, i'll send you some info regarding my S3-EFI/ITB kit(s)

Rick, 3.0 is the way to go.

Jesper, when did you live out here? And the P1800 is build for the wife. Thinking of a V6 motor.

Hi Jeff, see our website for more details on what's provided for an ITB application. Combined with Al's kit it's everything needed to go EFI, coil on plug ignition, and ITB's.

Looking great Al and Andy!! Can't wait to see it all come together.

[al lkosmal]

I spent much of the day.............getting things clean. I never media blast the cases or any internal moving parts. After blasting, parts always look great and clean, but I don't think that you ever get all of the media off or out of the passages..............so my approach to getting this stuff clean is fairly manual. The engine case gets pretty clean using the parts washer, but this half still has a couple of hours of work to go, by hand..with toothbrush, Q-tips, solvents, etc.....before it will be clean enough for assembly. gotta be a clean machine!!!!!

Im in... looking forward to seeing this build and your opinion of the Infinity system Al. Great to see you and Andrew working together on this.

David

[James Brown]

I need to come see this, Al

[evan9eleven]

Staying glued to this thread, as I'm going with the Rasant kit on a similar build in the future. Can't wait to see this thing go together Al!

What about soda blasting? Would that media & the debris it creates be easier to clean than sand? There's a thread in the engine forum about blasting internal parts & it was agreed that sand/glass etc... was not a good choice due to the reasons you mention.

Hey Al,
It's looking good. It's nice to see the the 3.0 getting a new life. I am looking forward to having a bulletproof motor coupled with Andrew's modern ECU and Ignition fed by your very cool ITB's. Should make for a very reliable daily driver. To add to this on my end I have upgraded to the ATO modern fuse Pane:l New company and new products. 'Classic Retrofit' 911 Fuse Panel and CDI+ ignition.
As for the rest of the car I want keep the suspension stock as well as the engine mounts etc. Want to experience it as a Mid 70's Porsche. With the exception of more Hp and just get in it and drive of modern cars.

Al, I am not currently able to undertake an efi project (time and money), but I remember your speed triple itb projects previously. I just didn't recognize the TBs.

I have been in contact with Darud about the Rasant kit, but once getting there I'll really like to do some of the work myself beyond the efi adaptation. What you are doing seems very attractive. I'll shoot you a pm.


Andy, I lived in the area while studying at NPS. I loved it!!! Left at Xmas 2014.

No more OT from me, sorry.

[al lkosmal]

My 1st priority is always to build a good, reliable, strong running engine....but i like them to look good too. Installing nice, shiny EFI parts over an ugly, old beat-up shroud seems wrong....so I typically spend a little time improving the looks of the shroud.
They are usually dirty, greasy, scratched, so this is my approach:

I do not paint these as it never looks right, to my eye, and doesn't seem to last.........I like to bring the original gelcoat finish/color back to life. To do this I sand the surface to remove/minimize the scratches/gouges. Starting with 320 paper on the worst areas and working my way to 1000....then I use rubbing compound. I buff that out and then follow up with wax.

Note; This is not meant to be perfect.........but it does work well and really brings the shroud back to like...in its original, mellowed out/aged color. Maintain the patina.

regards,
al

PS: I do paint the metal piece

Looks great Al!
