The SR20DET made a lighter and more balanced car. It was also a lot more money at the time. My 240 got an S14 blacktop swap, about $3k at the time, and the RB20 was $1000 and went into a $1200 240. Again this was a long time ago when you could still buy those cars. I believe the best swap might be the RB25DET if you can do it all well like Saabkyle’s build for example.
My previous and current daily driver have been I6s, it's one of my favourite layouts.
I'm surprised the Mercedes M104 only got mentioned a couple of times, they have definitely got to be up there just aren't as popular or commonly accessible as other brands.
I know of one with over 600k miles I read about in a magazine, only mechanical fix ever was a head gasket at 3xx,000 miles.
It is an incredibly well balanced and refined engine, and built like a tank motor.
Here is a video of my W140 getting a "smoothness test". After 29 years, 100% of the engine and accessories are factory original.
My previous car was a 2000 Ford Falcon with a 4.0L 'Intech' SOHC I6. I actually prefer this engine over the Barra which takes all the attention. Yes the Barra has DOHC but the variable valve timing required much more stringent maintenance. I know of two Barra powered Falcons that died due to being serviced once a year instead of by mileage, and in both cases, and I've seen it before too, the VVT seizes and snaps off the cams. Yes they can still cover 1,000,000KM if serviced every 10-15k, but my workmate owned an older SOHC for 120,000KM and didn't service it once. Got parked up at 410,000 due to rust!
Complementary vid of my SOHC's exhaust.
Interesting to note - these Aussie 6s are direct descendants of the Ford 200. They were enlarged and the heads were tweaked over the decades until they evolved into the DOHC Barra.
Had the 225ci in a 1963 Dodge Dart, and discovered that Chrysler had some interesting performance parts in their Chrysler Marine catalogue ... 4bbl carb on a runner manifold, headers, cams, and a little tweak with the distributor. I think there might have been some heads as well, but memory's vague on that. Fond memories!(Slant 6) It was a fine engine except being pretty gutless. The one in my old D100 pickup couldn't get out of it's own shadow. That had to have been the slowest vehicle I've ever owned or driven.
Absolutely. In their final turbo form the XR6 Sprint was nudging 500hp + 480ft/lbs from factoryThe Falcon 4.0L probably put out two or three times the horse power of the original 200? One of my first cars was a 65 Falcon with the 200 and probably with the 2 speed automatic if I remember correctly. That car was cute but very slow.
If that was a super slant six it would start right up...Was gonna rebuild this old I6 Ford until I found they’d been using 5w20

Not only that but the Barra turbo will handle 800HP on e85 on the 2007+ factory motors and will last a long time on a competent tune. Lots of people doing it now.Absolutely. In their final turbo form the XR6 Sprint was nudging 500hp + 480ft/lbs from factory
Fords Straight 6.Inspired by all the wrong or off-topic answers in the V6 thread.
What do you have for best inline 6?
I nominate Datsun's L28ET:

With honorable mention to the VR6, because it is really neither a V nor in-line.
The bottom ends will cop anything, but head work is absolutely necessary if you are venturing beyond stock outputs though. I've seen and heard of a few cases of the heads lifting from the block after a spirited sesh! This is the reason my brother in law wouldn't take his XR6T to the skids cause he'd also seen it too many times on budget builds hahaNot only that but the Barra turbo will handle 800HP on e85 on the 2007+ factory motors and will last a long time on a competent tune. Lots of people doing it now.
