I was thinking about this, and couldn’t they make up for the RPM with a smaller crank pulley?
It isn’t like this is the only motor that spins that high, how does Honda do it?
I’m just curious, I dig the project.
The crank pulley is ths denominator
What?
I’m not knocking the build premise because I do like one-offs. Its the performance to cost/effort ratio that I question. That being said…
what’d cost each of those two to put down their respective HP numbers? Also whats the cost / time on the HD gearset 2.6bar ready trans?
there are pulleys available for the sho engine so you can spin them higher w/o blowing up accessories so bad, but then you have to bump you idle up to 1000rpm so the engine doesnt overheat and so that the charging system puts out enough to not drain the battery
fine for an enthusiast to do to his own car, but obviously not a good idea straight from the factory
well a bunch of the effort in doing this swap is directly transferable to the production of parts for sale. For example the tranny adapter. Once alex’s car is fitted w/ one we can turn around and sell copies to others. same goes for the HBB’s, the exhaust manifolds, motor mounts. its not a HUGE market but there is a market for these things
supercharging a SHO to make those HP numbers isnt much different then supercharging a Mustang to do the same. The only difference is that SHO pistons are more expensive, and so are sho cams (if you so decide to install those things)
the HD gearset is $5000+, no idea what the development time is for that sort of thing but i think the company making the gearsets is the one also doing the design work for the parts, hence the rather high price.
Not every Honda motor revs to 9k, so if they’re making special accessories for the motors that do, good for them. I can’t see the “accessories” being the reason Ford de-tuned these motors. They de-tune everything…
Like I said, I was just thinking about it today at work…
Maybe they de-tuned it because they didn’t want it smoking its Bad-ass halo car the mustang GT. I have heard that stock for stock is pretty much a driver’s race. Pretty pathetic that’s Ford’s Muscle car can’t even beat its own family sedan of the same year.
that engine looks cool in there. 
make a cheezy lexan hood window to sho-case it lol.
I like the project.
i bet if he were putting a 2JZ in there less people would be bitching and it still would be a 3.0L 24V 6 banger with the potential for ALOT of power.

Why do you think the Grand National was retired? GM made the same mistake… stupid slow Vettes.
and for the matter, why GM wouldnt put the grand national motor in the firebirds for anything other then the pace cars… to good of an idea
while i do sorta dig this project and the originality im not sure if comparing the 2jz to a yamaha motor is realy fair. Everyone knows what the 2jz can do in stock form however can someone please tell me what kinda power a stock block yamaha can make with some boost? it better be in the 700-800hp range for this to be a good comparison.
im sure it could do that with good tuning. the number i heard tossed around back in the day when i had a SHO was 750.
it just wasnt worth doing it in the SHO cause you had no hope of putting it down to the ground…
plus most people that hot rod cars dont put the time/effort/money into properly tuning them so youll have a zillion people that will pop an engine at 400hp cause the ecu wasnt calibrated properly to every facet of the engine and then word gets around that “the stock XXXXX engine is junk, it cant take over 400hp”. there are a few examples that hold true to a HP limit (5.0 ford for example) but many just arent tuned.
thats what i thought about DSM motors till i saw what burchs car was putting to the wheels when tuned cause previously i saw so many dsm’s popping on the dyno at 400whp.

The Grand National and GNX were “retired” in 1987 because in 1988 the Regal/Cutlass/Grand Prix chassis went to a front drive platform. The GNX was rated higher than the 'Vette.
fords literature from 1989 states that the block crank and rods will withstand 700hp or more
the current sho engine dyno records arent publicly posted (due to a long standing rivalry between 2 of the sho guys) but if prodded they will both admit to 625+, which is done w/ pistons, a freshened stock bottom end, cams, porting and intake mods.
cranks only get polished, no regrinding or knife edging, rods get reused with only minimal clean up, no modifications at all are done to the block. stock windage trays, no crank scrapers.
like nick said the stock block crank and rods are good for a lot of power. if memory serves the current published reccord is 636whp on a supercharged car. It is a stout engine bone stock but to really push it hard is needs a set of stronger pistons. The ring lands tend to break when you run more than 15psi of boost. There are 2 guys that I know of running at least 25psi right now. One is on stock cams and intake with just a massive turbo and proper tuning. The biggest weakness the engine has is low oil pressure at low rpm’s. Premature rod bearing wear is the result and it is strongly reccomended that they are replaced every 100K unless you race the car then they are fine.
Shoot for 700 whp.
Then people will not poke fun.
how about running 2 alternators w/reduced pulleys?
i suppose if you ran then in series you might get the required 12v, if you can even do that
would probably be easier just to just design a new case that accepts better bearings for the stock internals so that the bearings dont die early
no series… series = 24V.

these engines can do pretty damn good for themselves, thats for sure
