Northstar ZR1 (Here we go!)

[Blue Flame Restorations]

Has anyone ever put a Northstar into a ZR1? Would it even fit? How similar is the Northstar to the LT5, physically??????? It would take the Northstar wiring and all, I'm sure.

I'm not planning on doing this. I just wonder if it's ever been done?

(this should be good):p

OK Brett......are you bored now??

I have one question..... WHY? (even consider such a travesty):confused:

I think you need another project (not the one you're asking about either!

:cheers:

Hey....Its the weekend....I figured I'd spice it up a bit.hahahaha

[Kevin]

why would you swap in a smaller motor?

[LGAFF]

Get you a$$ back to work!

I finished a 54 last night and have two 53s going at the same time. At least I didn't ask about dropping in a blue flame. Lol

Nobody is going to like this, but the new Toyota Tundra 5.7 variable cam at 381 hp is the most closely spec'd engine to the original LT5, but with modern controls and vvt, variable intake manifold tuning, etc.

then, if you could interface the new ecm to the CCM in the C4, an LS3,LS7 etc would be the proper thing to do.

Mike, Mike, Mike... What ever are we going to do with you? :rolleyes:

"...the proper thing to do" :jawdrop: (Oh gawd...) It's high time you drove a Z that has been fully ported and cammed and tuned - "FBI'ed", so to speak. Then LSx and ZR-1 would never never be mentioned in the same breath again!!;)

I'm going to eventually need an LT5 for my 90 that I bought without a drivetrain. Since LT5's seem to cost as much as an entire car these days, I got curious and searched Ebay for a Northstar, since it resembles an LT5. They are plentiful and a dime a dozen.

Now, would I actually drop in a Northstar? Doubtful BUT I do like to be different than everyone else. If the Northstar was already a 500+ HP motor (and it's not) my $3500 1990 ZR1 would actually be a consideration just for shitz and giggles. The car will never be a high dollar car anyway and I do have another Z for driving.

Reality is...........I'll be on the prowl for an LT5 over the Winter for the 90. So, NO NORTHSTAR for me.

Heck drop a LS engine in the car. Go faster cheaper and much lighter.:-D

The one thing I "would" do, if it was affordable, is to drop in an LS9 new ZR1 motor. Even modify the hood for the window. Now THAT would be cool......and fast!

Thats what Im talkin about,twin turbo.

The later cars with abs and the CCM have trouble talking to the LSx controllers... I think you have to live dangerously without the ABS and piggy back the speedo signal and some other things by retaining the original ecm to bridge the gap to the CCM for the gauges.

And then, You might have to use a Camaro LSx ecm without stability control, - old fashioned throttle by wire, and a stand-alone custom harness (which wouldn't pass engine swap muster in a strict state like California). I wish there was a kit, but the C4 market is kind of weak for the aftermarket.

an LS3 would be the ideal amount of power.

Google Speartech Harness. John SPEARS IS ONLY 10 minutes from me. He wired an LS for me in a 54. He is pretty tough at this stuff.

[USAFPILOT]

maybe the xlr-v supercharged DOHC 4.4L could fit?

[Kevin]

lsx is your best bet if you want to do something odd ball....but i don't see why you'd do it to a zr-1

[Blue Flame Restorations]

It's a $3500 ZR1. Who cares at this point? I have two more to make correct.

When I find the right LT5 for the right price, I'll buy it. In the meantime, I'll paint this one and let it sit in the corner with a cover on it.
