Pete84 Posted September 28, 2007 Share Posted September 28, 2007 Taking a look at some of the hybrid SBC swaps done with 280ZX's and Z31 300ZX's, it looks like the 280ZX's have a longer but slightly narrower engine bay, making the headers a tight fit but giving plenty of room lengthwise. While the 300ZX Z31's have a wider bay that is easier on the headers while getting kinda snug with a SBC. How well do said engine bays stack up for a SBC / LS swap? Clearances for headers and the front end accessories? I've been doing the run around with California smog info, trying to see what would fit better in the meantime. Anyone have any figures that might help? Rough ones, anything. Rather not PM eveyone that has done the swap to try and get some dimensions Firewall to radiator? And how much room you have between the front end bits and the fan? Header clearance? Custom, block hugger, rear exit? Thanks! Tried this in the non-tech board, but with no luck. Not sure why I tried it there :/ Quote Link to comment Share on other sites More sharing options...
Chaparral2f Posted September 28, 2007 Share Posted September 28, 2007 Once you get rid of fan shrouds and stock air cleaners getting a sbc into a 300ZX isn't hard. There is plenty of room on the sides and it isn't very tight front to back. Quote Link to comment Share on other sites More sharing options...
Pete84 Posted September 29, 2007 Author Share Posted September 29, 2007 I've been looking a the iron block LS truck engines, but a recurring issue is the fitment of the alt, water pump, p/s, a/c. http://media.gm.com/us/powertrain/en/product_services/2007/Photo%20Library/Gen%20III/Gen%20III%20Truck/07%205.3L%20V8%20LM7%20EXP%20LoR.jpg Looks like the LM7 might actually fit everything into the Z31 bay - might it? Found a picture of the 6.0L LQ4, and it appears to have the same dimensions. http://www.enginesandgearboxes.co.uk/site/media/engines/Isuzu%20engine%203.jpg Quote Link to comment Share on other sites More sharing options...
Racinjitter Posted October 1, 2007 Share Posted October 1, 2007 Pete, there is someone by the name of Ken in AZ that is putting a LQ9 into his Z31 right now as we speak. He has the problem with the alternator also. He aslo has a slight problem with the oil pan, it sits about 2" below the crossmember. But other than that It looks to have plenty of room to work on everything easily. Quote Link to comment Share on other sites More sharing options...
Pete84 Posted October 3, 2007 Author Share Posted October 3, 2007 I searched, and didn't get anything on that "Ken in AZ" - any links? The oil pan is very deep on the truck motors, might a winged Corvette pan work? Thanks! Quote Link to comment Share on other sites More sharing options...
