Thread: Fuel Economy - 3.5 V8

How time flies eh, guys? Posted a quick note two weeks ago and jibed about the juice costing $1.25. Two weeks later and another 10 cents dearer, make that $90000000000! no exagggggeration, Scousie!

Digressing, there must be some poor bastards getting seriously knocked around by these prices, judging by what's being 'dumped' on ebay. I think I saw a 96 D1 V8 two days ago which appeared quite okay for just $5000. Geeeeeeeezzzzzz!!! and there are plenty more for not much.....glad I'm not selling.

I just noticed your post title: Fuel Economy 3.5 V8

I thought those words ween't allowed in the same sentence

Hi All,

Interesting thread here as I am now the proud owner of 1981 RR
3.5 V8 Auto stock standard (motor wise).
What would you look at changing to improve fuel comsumption.

I was thinking of gas conversion but the mob that converted my D1 V8i
say they cannot fit it to RR because of the twin strongberg set up not
that I want to spend that sort of money at this time.

Will be changing points & plugs (this weekend) and taking it to local
mechanic who services and does repair does work for local car yard
that sells Landrovers /Disco's on regular basis.
Want them to tune carb's and check timing.

So would appreciate feed back as to modifications I should be looking
at

Cheers

Hi

Not that I want to recommend Jeeps in this website (considering I just bought an 86 EFI rangie) but a while ago I was looking at them and came across this guy

http://www.go.jeep-xj.info/

he has spent a lot of time trying to improve the power and economy of his xj cherokee and when I last chatted to him he reckoned he was down to a consistent 12 l/100k highway (from 16) and about 16 around town (as well as up from 130 odd KW to 165kw at last check!!)

Look at the engine and driveline modifications section and check out the info on the manifold swap. Does anyone know if this might work on RR - ie 3.9 manifold on a 3.5? Are they the same size/fit?

I don't know myself, only just started looking at options for my project. At the moment I'm tossing up between an injected or carbed 4.4 (I have cheap access to a rebuilt one) or just stick with a rebuilt 3.5 that came with the car and try to make that more efficient. I'll ask q's about that later.

Cheers
