You can do it, it’ll be full custom work. You’ll want to swap the trans too
The NorthStar V8 is connected to a 4T30 FWD transmission in Buick & Cadillac cars. This conbanation performs very well together however, these cars are not a 5,000Lbs 4x4.Shawn, the 4L30 won’t last too long hooked up to the v8, will it?
What would it take to do, besides a proper rebuild?Always a opition to beef up the 4L30 to handle more power
I am not the expert on these transmissions.What would it take to do, besides a proper rebuild?
Ballpark quote for a Northstar on a 5speed swap? Less than 5k?Absolutely there is.
The best way to go about it is to install the engine, electrinics and transmission from a Tahoe.
Another option is the Cadillac NorthStar V8 as it will bolt up to the MUA5 (with correct bellhousing) and 4L30 transmission. Add a Fi-Tech standalone fully tuneable ECM and you have a 436HP V8 with more torque you would ever use.
Welcome to bring your vehicle it to my shop for this repower.
I think so.Do the MUA-5 and AR-5 have the same bolt pattern? I imagine that they do.
Sh*t if it’s less than $5k I’m putting that on my wishlist!Ballpark quote for a Northstar on a 5speed swap? Less than 5k?
Well a decent low mileage Northstar is about $700-1100. The rest of the budget is installation and minimal fabrication costs?Sh*t if it’s less than $5k I’m putting that on my wishlist!
Not if set up correctly. If you harden them, they are as reliable as anything out there. I’ve seen 800hp twin turbo Northstar sand rails that do 80mph wheelies out at the Killpecker sand dunes!Aren't Northstar motors garbage though?
Referring to performance or reliability/longevity?Aren't Northstar motors garbage though?
absolutely. There are thousands of high mileage northstar cars. It’s no dumber design than the Toyota V8 (fourcam with starter under intake manifold) the Northstar is quite small for its size. Lots of midrange TQ. I may buy a low mile junkyard Northstar and harden it myself. I have access to a hotrod shop here, just need the time and money.Reliability. I have it in my head that they were bad motors, but I can't remember why. I think from like 20 years ago when I worked at a car dealership for a bit.
Thanks Bender. So it's something with known issues, and the issues have known solutions?
