best economical swap

[richyboycaldo]

Hi, my question is, I have a 240z in bad shape, and I am college student who works, so as I see most of you want more power etc, but waht i really need considering price wopuld be aropund 3 in summer is the best economical swap to give the better gas milleage, probably a 4 cyl, the sr20 is expensive. a crappier engine maybe from a sentra (not ser) maybe? or any other one? any advice will be great I am looking for some 30 mpg and not requiering 91 octane. thx in advance guys. Hybrid Z says they only do swaps for more power so no very helpful

You want a 4 cylinder? I don't think you'll find many (any) that have gone that route.

Best swap is to sell the 240Z and buy a honda civic..

Having a car that weight like 2300 pounds should be able to have great milage, in a 100 hp engine.

IMO, the most economical swap is another L6 motor. Venturing beyond the L6 motor, your definitely going to spend some coin!!!

My point was that virtually NOBODY is interested in taking a sportscar and turning it into an economy car. Sportcar owners are usually looking for MORE power, not LESS.

As I said, You'll be hard pressed to find someone that has gone that route. It just isn't an attractive idea to many people.

If you want a 100 HP 240Z, disconnect 2 plug wires.

your best bet is to find a L-24 and stick it in. By the time you mess around with a 4 banger and replace the trans and all the little things like radiator and such you will be into a hell of a lot of cash . If it is a rust bucket that you say , sell it as a parts car and move on to a economy car like an old Honda.

I am in the stick another L6 in - but if you want to do the 4 cylinder path try visiting hybridz.org there are a number of guys that have or are doing SR20DE or SR20DET swaps.

Mike: He's looking for less power, & better mileage, and has already been to HybridZ.org

thx, Gonna check the prices in the sr20de and what do I need. hope is way cheaper than the turbo

You also should know that the SR20DE/DET that people use in these swaps is not a Sentra engine. The Sentra engine is a front wheel drive engine. The engine used in these swaps is a RWD, non USA engine. I don't like them in a Z but that's just my opinion. I'll tell you what, though, the one SR20DET-Z I have seen was damn fast! But if you're looking to do a 4 cyl swap for economy reasons, buy a 4 cyl car instead.

IMHO, I would hate to see a 4 cyl Z swap. As an alternative, why not look at a Miata? Used Miatas can be had for cheap, thier engine is bulletproof, parts are also relatively cheap, it gets 30mpg even with spirited driving, and handles like a go-kart. Granted, you'll never blow anyone's doors off at the line, but that would be rare in a Z as well (unless you go the V8 swap).

Personally, if I had to do a swap on a Z and wanted economy as well as a little flair, I'd put in an Nissan LD28... that's right, a diesel. It's been done before (http://www.veggiecar.com), the LD28 motor is a basic bolt in swap althought no swap is without a little creative engineering. The only problem is that LD28 motors are becoming rarer and rarer (81-83 Nissan Maxima). Too bad really, or I'd be seriously temped to do it myself. Biodiesel, a very real and logical alternative to gasoline. Do a little reading, I think we will be hearing quite a lot more about it in the future, especially if gas prices top the $3.00/gallon mark. (or at least we SHOULD!)
