Honda Del Sol 50MPG goal

Hey econo friends my name is Carlos I have been modifying cars for 8 years but mostly trying to make more horse power not to worried about MPG my CR-X only got 20-25 MPG I have played with MPG in the past and only got 40mpg in my 97 civic coupe with a integra LS 1.8L motor I recently got a job that is 35 miles away and finally tested my Honda Del Sol first week I got 34MPG second week Im at 38MPG with wiper delete and reduced my speed 5MPH I do have full functional A/C and not getting rid of it


Future mods I bought a civic Vx transmission and grill block off and my friend has a body shop and will be deleting Auxiliary lights and rolling my fenders like the Honda insight

Welcome! We love Honda's here! Your prior CRX was an SI??? Pretty bad for a CRX
unless you were always standing on it!

My best w my '87 is 62.9 mpg so far.

I'm sure, w some patience, and work; you CAN reach that 50mpg w your current ride.

Welcome to EM! This fellow sold a Del Sol with a Honda VX drivetrain back in May 2008 :

Don't know what happened to him, but your thread reminded me of his achievement.

50mpg is more than doable. In 2006, krousdb aeromodded a Del Sol and averaged 58mpg from it. If you search back through Cleanmpg and Gassavers, you can find some of his old threads about modifying his Del Sol. Below is his thread about installing the underpanel on his Del Sol:

Just a thought, what cams do you have in your engine? Do you have adjustable sprockets?

My idea would be to put the stock USDM cams back into the motor and adjust the VTEC kick in point so that it would come on later, then get a J&S Safegaurd knock controller to mind the store when it comes to detonation. Good thing that Hondas are pretty good when it comes to cylinder head design.

I had thought about doing a Honda like this, but with a D series VTEC. All the VX mileage goodies but a lot of compression, pump gas or E85, and a custom ground cam. The low speed lobe would make more bottom end torque than stock so that it can be short shifted around, while the high speed lobe would be about the same as stock but with a little more lift. I asked the cam grinder if he could do something like that, he said "Sure".

Initially, I wanted a more Jeckyl and Hyde grind that would be do what I described above with an 8500 rpm high speed lobe, but he said the transition might be schizophrenic. Now that I think about it, I wouldn't mind that. As long as the engine is above 3500 rpms it shouldn't matter.

But all that got thrown out the window as of yesterday.......... a neighbor just offered me a FREE Toyota 2TC mini hemi 1.6L 4 cylinder out of an early Corolla. Life just got interesting!

The good thing about Honda's is they are versatile you can achieve 11:1 and 12.5:1 compression with a combination of stock parts

50 MPG from a del sol should be within reach. I remember when I had my 93 Del Sol S I could hit 38-40 MPG at a speed of 70 MPH if I didn't do too much city driving. Welcome to the forum.
