Best jap engine?
Discussion
I don't know all the acronyms but I would have to say Honda's VTEC engines seem pretty impressive.
And for tunability, the EVO engine - largely untouched in the last 10 years IIRC.
For real impressive feats of manufacturing, though, 600cc bike engines are marvels. Over 200bhp/litre from normally aspirated engines with all sorts of race-car engineering like titanium valves and stratospheric rev limits.
In a roundup of bike engines in BIKE magazine the Yamaha R1's engine was selected as the best (1), due to its clever EXUP valve in the exhaust which increased backpressure at lower revs to boost low-down torque and opened up at higher revs to breathe freer, liberating more power.
Clever chaps, those Japs!

LOL obvious choice is the vvti 2JZ-GTE ( nick name 2JZ-GTTE) 
TBH Gaz most Toyota, Nissan, and Honda performance engines are absolutely spot on. Scooby's and Misti's close behind.
I thought the NSX type R engine would be a contender!
The C32A certainly is a contender. Theres a shop near mine AVO Turboworld, they had a race prepared NSX-R with twin Turbos on it... looked pants but alledgedly is fast as a fast thing!

extremely impressive flexibility. I've heard that Mitsubishi are thinking of dropping out of rallying. If so, imagine if they put a 3 litre turbo charged engine in the Evo X (without the need to stick to 2 litres for rally rules). That would tick all the boxes.
At one stage I believe Ford were planning a new 3.0 turbo 4x4 Focus. I think this is now shelved.

btw, Gaz and Terry, could i be really cheeky and ask for a recomendation on the business part of my profile
I would if I could mate! can't find anything that says "reccomend this oxo loving gimp to power test your car"
Serioulsy, I can't see how!

Agreed!
I put a vote in for the Lexus V8, 1UZFE (in UK) fitted in the; LS,SC & GS400. A '92 N/A puts out 260 ponies as standard & iirc later ones <>280. Beautifully over engineered, almost indestructable & so unstressed it makes an RB26 look like a hothouse flower
Have seen a tubby conversion, mated to a mk III Supra box-WILD If I were doing some kind of V8 dropin/conversion I'd certainly highly consider this as an alternative to something from the US.
