Why NOT Northstar?!!!


Recommended Posts

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.

I've seen several hot rods with a north star V8 as well as sandrails.

 

Here's info on an adapter to adapt a RWD 700-r4 transmission to a northstar V8

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.

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?

PalmettoZ, It is mine...L24,290/490 Isky cam, Weber 40DCOE Triples, 110 shot sportsman fogger(direct port wet system). T5 with 4:11 diff. I don't know what the numbers would be but it's not enough.

MAG58, 469 h.p.@6400rpm 439lb.ft.@4400 in stock form. How much power can you REALLY use with these light cars? 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.
