New turbo for the Honda

[Christ]

He's using the in-dash shift light... funny.

I don't think he's actually using it, but it's still working. That's what I think is funny. I've seen guys that have removed the OEM circuit for that light, and added a shift light of their own with a variable setting on it, though.

Bump. A friend of mine is a big Formula 1 race fan. He insists that a small turbo that would produce great power on low-end RPMs would work for hypermiling applications--help raise FE numbers. The discussion of the Lupo TDI got me thinking again about this Holset thread and the 2007 Civic TDI sold in Europe. Anyone have an opinion on this application and its effectiveness? I wonder if the 2007 Civic turbo can be adapted to a 1998 gasser Civic. I wonder too about the little Lupo. The learning curve here is as steep as possible for me, and any "plans" are far-off. But any thoughts on the topic from the forum would be much appreciated. -james

I know it works with diesels.
The theroy behind it works by using 2 heat engines to do work from one heat source.

In a gas engine if you size the turbo properly you can boost fuel economy, but if you go crazy with it and size the turbo to run in say the 3600rpm and up range, it will just be an exhaust restriction when driving normally.

You dont want to use a Holset VGT designed for a diesel on a gas engine.

Thanks guys... the article is great. And knowing to close-off the Holset idea is useful. My car is a loooong-term project. I have had it for a decade and I'm going to wear it out part by part and rebuild it into a new car. I'm learning, preparing.

Another question: obviously I could move down from my 1.6L engine to the previous Civic's 1.5L--maybe even 1.3L--with the added power and with my lighter car. I could also go for much taller gearing with the added power and still be able to climb hills about as effectively as now with my 1.6L, no?

My best increase in fuel mileage was with the Greddy 15G turbo and
Greddy cast turbo manifold. This was all done using a Neptune Management system.

You could easily go with a 1.5L and still have great power when needed.

Feel free to pm with any questions.

Has any one considered running water mist or water methanol mist injection on there turboed gasoline engine?

You mean that water injection stuff? I have read about it a little. Seems dangerous to the engine if your system is unreliable. But I have not seen much in the way of posts on this site.

Thanks for this pgfpro. I'll read some more and pm you if I have questions now or later. Thanks. -james

Water mist injection has proven its self on turbo diesels.
With N/A gassers it seems to do little if anything for FE, it does appear to reduce NOx and that is about it. As far as I can tell it hasn't really been tried on turbo gas motors for fuel economy. Using water and water methanol on forced induction gas engines to boost performance goes back to WWII.

You would need saftey systems to turn the water on at the right time. This is how I would wire it up:
The system would get power from an "ignition on" source or through an oil pressure switch that controls the fuel pump. To control the water system turn on you could use MSD rpm activated switchs and adjustable boost/vacuum switchs.
All those switches and what not would send power to the coil of a relay.
Then relay contacts would send power to the water pump and/or solenoids when directed by RPM and boost/vacuum switchs.

Or get about $500 to $800 together and call snowperformance.

I plan on running water injection on my diesel for economy and water/methanol in my car for added performance with out running expensive gas. I would like to run around 12:1 compression on my next engine build.
The water injection system I have put together for my diesel has about $200 total into it so far. I bought enough parts to build a 3 stage system, 1 pump, 2 solenoids, 3 adjustable boost switches, 4 mist nozzles (each a different size for tuning) and a low water level float switch. (still need to find or build a water tank).
