snell1884 Posted December 18, 2009 Share Posted December 18, 2009 I have searched and searched but I can't find any "successful" swaps with a northstar engine. The only problem (other than cost) that I can find is the transverse mounting. Since 04 the lh2(325h.p.vvt) and in 06 the lc3 (469h.p. supercharged) have been longetudinal with 6 speed trans. Are they too wide? Hard to mount? I really want one of these in my 240. This is my first post but I have been building my Z since the 80's. I am finally going v8.

blackice280zxt Posted December 18, 2009 Share Posted December 18, 2009 I dont see why it wouldnt fit. With the 6 speed I have seen northstars in fieros but those are transverse also. Quote Link to comment Share on other sites More sharing options...
MikeBZ Posted December 18, 2009 Share Posted December 18, 2009 (edited) I've seen several hot rods with a north star V8 as well as sandrails.

Slammed68 Posted December 18, 2009 Share Posted December 18, 2009 Nobody uses them because they supposedly cannot be rebuilt, and really, the LSX motors can be had cheaper and have much more of an aftermarket, and still be more reliable. Seen some northstar swaps in fiero's, but like ^ said, haven't seen a longitudinal one. Quote Link to comment Share on other sites More sharing options...
blackice280zxt Posted December 18, 2009 Share Posted December 18, 2009 You can rebuild a northstar you just have to be careful. I messed one up and then got it right the second time. The problem is in the block where the head bolts go. They likr to strip and the pins like to get boogered up Quote Link to comment Share on other sites More sharing options...

Your second photo has a Z motor with triples and a really nice nitrous set-up. Is that yours? Has it been on a dyno and if so what did it put out? Looks like a serious engine setup.

MAG58 Posted December 18, 2009 Share Posted December 18, 2009 The Northstar wasn't exactly designed to be an easily rebuldable motor, like blackice said, the block (in many cases) requires time-certs for the head bolts and the block is a die-cast open block design. Good for temperature control and cost effectiveness (uses less material than sand cast) but not so great for big power numbers. Who knows though?

I did see an upgrade that nets over 600 h.p.http://http://www.d3cadillac.com/vehicles-XLR-and-XLRV.php If that's the factory supercharged engine, than it's not an open deck like all the other northstars, it's a different block and an entirely different animal (much more rare and expensive than your dime a dozen JY Northstar). CHR Fab builds a bunch of these motors for performance applications, if you want big numbers they're the people to contact. And getting big power numbers is not a problem with an open deck motor. It's getting them to live (for any extended period of time) at these power levels. 470hp may seem like a ballistic missile to some and a ho-hum grandma mobile to others. It's all about your frame of reference. When you get to what those kind of people would call big power (remember there are at least a few people on this board that have well over 800hp to weild under their right foot) CHR Fab is the only people I know of that stock darton sleeves for the Northstar.

Though having a supercharged twin cam V8 with a warranty is pretty great. Imagine pulling into a caddy dealership with your Z. Quote Link to comment Share on other sites More sharing options...
