noramost Posted April 8, 2018 Report Share Posted April 8, 2018 More money than sense Nissan is flexing its genius muscle again offering us a variable compression engine https://www.caranddriver.com/reviews/infiniti-kr20-variable-compression-turbocharged-engine-prototype-drive-review the KR20. We always needed 8:1 – 14:1 compression ratio with 23lbs of boost. I think datsunfreak should build his 28th 510 with one. Use a $40,000 donor to build a $6,000 car 1 Quote Link to comment
thisismatt Posted April 8, 2018 Report Share Posted April 8, 2018 Crazy connecting rod design :P Now you can throw two rods at the same time? Quote Link to comment
Icehouse Posted April 9, 2018 Report Share Posted April 9, 2018 Seems so overly complicated. The should just focus on electric. O and make a small 4 cylinder engine, rear wheel drive car. 2 Quote Link to comment
datzenmike Posted April 9, 2018 Report Share Posted April 9, 2018 With 5 speed standard and not CVT. Drove over 1,400 miles over the Easter weekend in a Toyota iM. There's virtually no engine braking for corners. I sure is different Quote Link to comment
Lockleaf Posted April 9, 2018 Report Share Posted April 9, 2018 I found this engine tech interesting and i am planning on watching how it performs in the market for sure. Also interesting is the Mazda skyactive X. Compression ignition (diesel style) gas engine. Supposed to only use spark plugs until it's up to operating temperature. Quote Link to comment
datzenmike Posted April 9, 2018 Report Share Posted April 9, 2018 Direct injection should work on it. Quote Link to comment
Stoffregen Motorsports Posted April 9, 2018 Report Share Posted April 9, 2018 The old 12 piston 6 cylinder seems more effective. Simpler too. Quote Link to comment
noramost Posted April 14, 2018 Author Report Share Posted April 14, 2018 The old 12 piston 6 cylinder seems more effective. Simpler too. Your shop looks exciting, since you are old school have you ever considered building anything using a LD28? I hear with twin turbos it will produce 1100HP and if you ever get to see inside one you will get to see what the good stuff looks like. I would shim the injectors to their maximum brake point and achieve 48MPG so it's possible to experience more G's with more MPG 2 Quote Link to comment
Stoffregen Motorsports Posted April 14, 2018 Report Share Posted April 14, 2018 Thanks. I have never used an LD28 in diesel form, but i have used plenty of the LD28 blocks and cranks to build 3200, 3300 and 3400 cc Z car motors. The last one I built was for Hoover Chan of TurboHoses and Noble supercar fame. It made 650hp. That was a long time ago. I don't build engines anymore (if I can help it). I do mostly trucks now and a lot of V8 swaps. 1 Quote Link to comment
