Engine Swap: Which Would You Choose!??

What that article is describing is using sintering to create a solid intermediate form for forging. The term "powder forged" is quite disingenuous, at no point is the powder itself forged. It is instead formed into a shape which, once sintered and subsequently pressed between a set of forging dies, will have little or no extraneous material needing to be removed.

And the rapid prototyping process you are referring to is called Selective Laser Sintering (although it can be done with electron beams instead).

In either case, it still involves sintering.

How do you know this, little detail?

I didn't invent the term, but that's how they're advertised probably to differentiate them from cheap OEM sintered rods (Focus I believe had sintered rods), and the conventional rods. And at the same time, their process has to start with the powder. I imagine that they are a pretty good value as they can probably maintain closer tolerances on their weights than ordinary forged rods. BMW's M V10 used this tech apparently.

Point is basically that the options available to the SBC community kick our ass. They are getting application-specific parts at OEM level manufacturing at good value. Whereas most import stuff is more expensive and machined from generic 'close enough' forged blanks, or from billet.

It's a great engine with excellent throttle response, once it's coupled to a light flywheel and proper manual transmission, along with good flowing intake/exhaust.

In the BRZ you could use the 2GRFSE version, since it is designed for longitudinal mounting. Only thing that sucks is you will have check engine codes, since it expects and automatic gearbox (no MT in the IS350).

What about the IS250's tranny? or the one in the Tacoma? They're bolted to variants of this engine (4GR-FSE and 1GR-FE respectively). Could those work? Or heck do what Lotus did and jack a toyota 6 speed diesel transmission for it lol.

I believe the starter is mounted on opposite sides on the FA and EJ.

How high is high? There are some stick LS6 cars that bang gears at 8500rpm. One of them is actually a stroker. Those cars also have big donkey **** cams in them. You wouldn't use a cam like that in a road race car.

Keep the lift under .600 and you should be pretty good. It won't make crazy power but it will live through 30 minute sessions. If you want to go wheel to wheel racing, stock LS3 with a dry sump.

I get envious looking at the pricing these domestic V8 guys get on their parts, plus the options they have (especially the SBC...).

Ahem...we also win at Long Beach and Le Mans.



Katech builds those motors. They also have a consumer division. A lot of THAT tech has trickled down too. And it's awesome.

TwinTurbo H6 from the 997 GT2, not sure what the engine designation is.

Haha.. "cost no object"

Actually I would grab that new 4L NA H6 from the new GT3


For a more realistic swap for a DIY-er.. if these bell housing rumors are true, the 2GRFSE would be wicked in a BRZ/FRS

Regarding LSx wonderfulness:


Stock LS2 bottom end, shaved stock L92 heads, 222/230 .597" cam.
Total street build for daily-drivable street car.
Just passed RI emissions with two high-flow catalytic converters.
Did 462 miles on one tank when I brought it up to RI from TX, fill took 15.9 gallons (that's 29 highway mpg, folks).

Yee haw...

[bimmerboy]

If money were no object: Lexus LF-A V10 engine. \thread


Realistic swap: EJ207 JDM STi engine + basic bolt-ons+tune,

Rollin....in my five point oh.

2uz would be cheap any seen this done yet?

Yurp. Who needs more than one cam?

What's the compression with the milled heads, what's the LSA on that cam, and what cam profile did you go with?

Nice thing about those Fox body motors, you blow one up and you get another one for like 150 bucks.
