Renegade Conversions in Vegas has all the hardware to facilitate a pro installation of small block powered 914s. These days they are building them with LS motors and Boxster transaxles.
That small block Chevy measured around the same horsepower as the 914/6 GT but the "little" Porsche engine produced lot less torque than the Chevy. Apparently in 2020 a 914/6 GT was sold for $995,000.
Back in 79 I bought a 914-6, kinda used with no motor. Got lucky with a friends shop had one the owner wouldn't pay for, & had been converted to 3 side draft Webers. Didn't know better, thought the body work was stock (lol, no internet), but it used 10" wide tires with the flares & had an air dam & A whale tail! Definitely was fun, cornered unbelievably well! Sure wish I had kept it, but couldn't find storage as A poor college kid & got offered WAY more than I had in it (paid all my rent & tuition for 2 semesters!)... Yours may be a bit unpolished, but might be a load of fun! Thanx !
It's a fun little hooligan for sure. Other than track day with buddies, it would be an obnoxious blast "street legal" and just taking it to cruise-in nights or maybe burnout contests. Or race it for pink slips and purposefully lose HAHA!
I must say I'm concerned about the angle of those half-shafts too; I don't know how you're going to be able to fix it, short of a major re-location of the engine, but I'm sure it would be a weakness if you were racing the car. Still, I think it's a project worth pursuing, if you can fit it in with all the other amazing stuff you do!!
I had the same issue with my 65 Corvair when someone added a hokey pressure sending unit. I replaced it with a brass 45° tee. This car has great potential. Hope to see you road race it soon.
You're pushing a lot of torque/power through that transaxile. Don't forget to correct the power at the wheels that you measure on the dyno to power at the engine shaft when you are comparing the SBC output to the 911's engine output. You would want to increase the dyno numbers by about 12%-15% for the comparison.
Just as a heads up, I saw a substantial arc from the distributor while you were peaking the RPM ; it was on the passenger side at around 4:04 in video. Looks like it went from the distributor to the exhaust. First time I saw it was a yellowish streak and while trying to get the timestamp it was just a white sprite right below where the body work is laying on the exhaust
I saw that during editing couldn't decide if it was from the exhaust or a spark, didn't look like it came from the distributor. I will look back it frame by frame.
This is one of the most overlooked, underestimated baby beast Porsche ever made. Such a cool red haired step child....But why a V8? Wouldn't a V6 HO be an easier install.
That poor engine sounded like a giant bowl of Rice Krispies. Those drive shafts look too scary to race. I had a 914 in the early 80s we swapped in a 911 engine it became a Very fun ride. It went faster than I could 😊 I loved that car.
Looks like a big job to sort out the transaxle misalignment, but if you need to fix oil leaks and pull the engine it would be worthwhile. Correction of that and shift linkage would be top priority if putting on the road again Good luck on the project
Looking at info on the net it looks like cv joints can run at least 15 degrees out of line. Transmission losses will be much higher and they will wear out much faster of course
Wouldn't the HP rating for the Porsche transaxle be the power being put through it from the engine? The dyno is measuring power at the wheels, which should be much less than power at the clutch. I suspect the transaxle doesn't have a long life ahead of it.
Not much sense after the fire wall has been cut out, it would not be much fun to drive as is, wonder why a junkyard V6 was never considered, less cutting and reliable like the V8.
Had a 72 914 2.0 that I had the motor built by Bill Rathbun who was a nationally recognized VW dragster racer. I don't remember the power numbers but I do remember every time I got on it I destroyed a CV joint. I'm surprised your CVs will hold up to a small block Chevy.
Grumpy is right. Sounds like it needs a good carb tune. I'd be concerned when it's making full power again it's going to be a bit much for that transaxle. It might need to be detuned unless that transaxle has some stronger internals you could buy. Very cool car
Thanks for somebody who pronounces "Porsche" correctly. Iike your videos, no Hollywood, and addictive watching you troubleshoot your cars.

Yup! I'm going to do it. I had a 914/6, 2.2S 200hp. Loved it, wish I had kept it. Raced it. Now building a rally car.
I don't care what you do with it next as long as you keep making videos of it. Even if it explodes, it deserves to go out in a blaze of glory!
Man does that thing look sketchy. Love it. I think I'd wear my flamesuit even if I was just going out for milk.
That is why I ran it with the engine cover off and a fire extinguisher near by.

So unique a project
great stuff thanks

GUARANTEED not to be another one at your local Cars-N-Coffee :-) Love It!!!

Its up too you Peace out

My 69 911T one if the not first 2.8 RSR clones had 110 hp.
We presently run a 2.8 producing 300 hp but the intermediate plate is steel
Wouldn't the HP rating for the Porsche transaxle be the power being put through it from the engine? The dyno is measuring power at the wheels, which should be much less than power at the clutch. I suspect the transaxle doesn't have a long life ahead of it.
I have a similar setup, super fun
Make it a autocrosser! Tune it so it runs better, change out the wheels & tires, fix the oil leaks then race it!
👍🏻💯
Obviously a major mod, but wondering how involved it would be to move entire drive train forward 3" give or take.
If you saw the first video the firewall behind the seat is already cut out for the front of the engine.

They probably won't!
Cool car id rallycross it for sure!

Very cool car
You have a pre 73 914
With the way you built it it will tear the chassis apart
901 street 200 hp, race car 225hp
This is a 4 conversion so the axles were designed for 100 hp
Sylicone monster
needs a bit of tuning....lol
You butch the fenders so your running centerline 8.5 x 15
the 901 trans will be fine.
WHY?
might have gotten better power if it wasn't running like a bag of crap
I would have tried to fix the problem of how it runs before I wasted Dino time
Switch to centerlines
So replace all the shifting linage bushings and good to go
Wrong Carrera 6 225 hp
Seems a waste of time and materials.
