Thinking of ditching the turbo
It's been one helluva ride the past 6 or so years.. but I'm feeling like it's time to move on.
Sooo fellas.. I'm thinking about ditching the turbo and going back to NA.
A few reasons... NA is so much simpler, it'd be nice to get away from E85 and go back to gasoline and take the car on a trip, I'm wanting to install a vintage air AC system (intercooler is in the way), it'd be cool to have heat again, it'd be nice to ditch the dual disc clutch and go back to a single disc setup (dual disc has chatter and is grabby as hell), this power level and my driving style has eaten two built transaxles $$$, yada yada yada
Here's where I'm at now:
2276 ARPM Case, 82mm old school Bugpack crank (Porsche rod journals, VW mains), Carrillo Porsche length rods, forged 94mm pistons total seal 2nd rings, zero deck with a .050" copper shim, Cam is an old DRD grind 292 duration 486 lift on 112LC
CB 044 Heads 42x37 D-Ports with cut down exhaust guides 50cc chambers (was 60cc but had to flycut a trench from detonation), CB match ported end castings, Pauter 1.4s, Stainless 1-5/8" Header (built by me), Comp ball bearing 62mm T3/T4 (yes it's a bit too big but wth)
10.5:1 Compression Ratio (remember, E85)
It runs great off boost and really comes on about 4k rpms and up.
So I'm thinking of selling the heads, rockers, cam, intake setup, water intercooler, header, turbo, bov, wastegate etc..
Keeping the case, crank, rods, pistons and cyls.
Looking at going with the panchitos or ported 044s and the idf style throttle bodies or a center mount idf with efi end castings. Maybe a sidewinder header and a much milder cam. The panchitos 57cc chamber volume will put me around 9.5:1 with .050 shim.
What suggestions do you guys have on cam, heads, exhaust etc?
This is the only real performance vw motor I have ever built, and rebuilt, and rebuilt again haha..

I hate to tell you this but your getting older .
What I can see in your pix is that you have you have more than a good start at being older.

By-the-way, remember the need for speed doesn't go away completely and I am not sure that the right foot is always connected to the brain .Ol'fogasaurus wrote: ↑Thu Aug 01, 2019 2:12 pmWelcome to the club!

Looking forward to seeing more building on your toy like I have seen so far. It makes me so jealous!!!!!

Re: Thinking of ditching the turbo
I would say go for either fk8 or cb 2288, cnc ported panchito's, your 1.4 rockers and stick with the 9.5 cr. It'll have good street manners down low but have a bit of bite up top, use cb's 40 idf throttle bodies on idf manifolds. 1 5/8 exhaust of your choice but a good merged system.

Have you raced that in the quarter? If so what time has it run?

Re: Thinking of ditching the turbo
IF you're really wanting to 'go down that road', I'd do it in baby steps. I'd leave the engine as is and just pull the turbo off and change exhaust... the 10.5:1 compression ratio will work fine with premium gas.... Drive it like that for a while and see what it's like. If you want a little less cam change the rockers to a less ratio set. I'd leave the EFI as you have on it and just a small tweek to the tuning and you'd be going down the road and not out much money. And you wouldn't be too far 'down that road' if you decided you wanted to come back to the dark side.... Then go from there.
(((OR just pull the spring out of the BOV and run it around with no boost and the engine will still be really impressive when you pop the lid... Just thinking some more LOL)))
If your planning on doing all those wholesale changes, I'd think about selling the engine as a complete running engine and then building a new one to spec... Might be able to get more dollars for the complete engine than a lot of parts... Just thinking.
Mine was set up real close to yours on E85 and I just lowered my compression (for pump gas) and added a methanol injection to handle the moments of insanity/boost or just getting on the freeway.... Seems to be working really OK

Re: Thinking of ditching the turbo
Could just make me an adapter pipe to go from the turbo flange to a stinger and cap off the wastegate.. try it and see?
I couldn't part with the ARPM case and Bugpack crank.. be hard to replace..
I still have my pipe I made to go from turbo to throttle body (before I built the intercooler). I guess I could stick that on there and go to methanol injection instead of the intercooler.. then the AC would fit with some creative belt routing. Probably have to go serpentine to make that work.. wouldn't be too bad.
Starting to wonder if this post is a cry for help to convince me to keep the turbo haha
What meth injection kit are you running?
