The beginnings of Eco modding. (What car should I get?)

I saw you mentioned an EGR delete - wouldn't that make your fuel economy worse?

I'm not a genius, guys, somebody help me out here. I thought part of the point of the EGR was to help fill the cylinder with neutral gases, reduce pumping losses and cool things off a tad.

[Daox]

That is true. Cooling things off a tad allows for advancing ignition timing which improves efficiency and even power.

Too bad the O.P. hasn't logged in since he started this thread!

So many questions & suggestions.

Man a diesel swap on Xterra! Man I want to do that so bad! What engine and transmission did he use? And I actually got 3 more miles to the gallon when I deleted my egr on my truck. I was on a trip o Utah and I was getting 12-13 on the highway. Deleted the egr then I started getting 15-16 mpg strictly high way. i always thought the cooler your intake was the more efficient your engine would be because when the cool air enters the combustion chamber it expands when it heats up giving it more power but I'm not an engineer and I don't have all the tools to test that properly.

But yeah I am thinking of getting the civic hatch. You can usually get them super cheap which won't make me feel so bad when I do the areo mods and weight reduction. Which ones have the lean burn mode? Does that system work good at all?

[MetroMPG]

The VX is the lean burn Civic hatch. It's the only one ever sold in Canada (HX was the coupe also sold in the U.S.)

Lean burn works amazingly at light/moderate loads. EG. highway cruising. Lean burn, good aerodynamics, tall gearing, and low rolling resistance are why the 1st gen Insight can get 75-100 mpg US on the highway.

[Ni87]

Oh okay that makes sense. I wonder what transmission is in the insight and if it would take a d15 �� That would be interesting to find out. Yeah that's the one thing that kills those Hondas is the gearing. Has anybody successfully swapped out the 5th gear or done the spur and pinion? Insights are super hard to find around here. Even online. If I could find one I'd probably go that route.

[Ecky]

Pretty sure it's unique to the Insight. It *might* swap with the 1st gen Civic hybrid, but I'm almost certain it won't mate to a D series.

On that note though, the 1st gen Civic hybrid has gearing nearly as tall. It's almost identical to the Insight's drivetrain, except it's a 4 cylinder 1.3 w/lean burn rather than a 3 cylinder 1.0.

Actually it's not a swap. Nissan offered the XTerra with a Brazilian MWM Sprint 4.07TCA (TCE for the common-rail versions) 2.8L 4-cyl turbodiesel, backed by a 5-speed manual Eaton FSO 2405 transmission, for the local Brazilian market and regional exports to Argentina. There might be more of it in other countries such as Paraguay and Bolivia, presumably stolen in Brazil and Argentina. The same engine had also been fitted to the S10 and the Blazer in Brazil until 2011.

Wow that would be so great! I want to do a diesel swap in this thing so bad. It's probably pretty hard to get that engine and trabsmission in Canada eh?

Not so sure if that would be so hard to get that transmission there in Canada, but I'm sure it would be easier for you to get a JDM Nissan YD25, QD32 or ZD30 engine.
