<\/a><\/p>\nThey went out of production in 2018 but are now back and you can buy one again. The engine was designed with assistance from GM LS experts, Katech and carried on developing the unit for a wider, universal crate motor purpose.<\/p>\n
Although I have read stuff that it\u2019s a perfectly scaled-down GM LS3, that isn\u2019t strictly true. It is based on the architecture of the LS series but is actually 25 per cent smaller, 66 per cent lighter although it is true that with four-cylinders it is effectively an LS engine cut in half across the Vee.<\/p>\n
American V4, with their other partners, Pratt and Miller have been offering the unit, officially called the MV4-ZR \u2018Baby Block\u2019 V4 in crate form as a transplant proposition to owners of the Polaris XP1000, which means a hefty power increase from the 110bhp that has as standard.<\/p>\n
There\u2019s also going to hot rod potential for it not to mention small aircraft and of course, it seems a perfect engine for kitcar use. For example, a Mazda MX-5-based kitcar would get an instant and healthy power hike, as the 1650cc American V4 punches out 180bhp out of the box. I can only imagine that if you bolted a nice little supercharger kit to it then 300bhp should be easily attainable.<\/p>\n
In the States, it currently costs $10,220 (approximately \u00a37747, when I checked) and for that, you get the ECU, fly-by-wire throttle gubbins and wiring loom, although once it\u2019s shipped here and all the various extra costs have been added, I\u2019d expect it to cost nearly as much as the current dollar price in the UK.<\/p>\n However, it remains an intriguing and frankly, quite exciting prospect. We\u2019ll be bringing you more on this one.<\/p>\n In the meantime, visit www.americanv4.com<\/a> ENDS.<\/strong><\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":"<\/a><\/p>\n
