Also driveability with the si transmission made it worth driving. hf was a waste. Gas mileage is one thing having a car that is slower than a mini van is another.

Re: Flash944's attack on a 50 MPG beater
Cx/Vx are both happy cruising around under 2000rpms...the CX is a dog but at least with vtec-e on the Vx you can pass on the highway...The gears are very long...I'll tell you driving style has a lot to do with mpg, if you accelerate at a crawl, which i feel like you will with the cx trans. Atleast I can say the VX was designed to keep the revs low, when it isn't in vtec-e mode its onlying using 3 of the 4 valves per cyl (which also creates a swirl effect in the cyl) but I can crusie along all day at 1000rpms and its very happy, drop a gear...or 3 and get the revs up to 2500 and I can pass a geo, lol its actually moved fairly well for a car getting 50mpg...anyways I think I got off on a tangent, I think the trans is going to leave you out side of the efficient power band which might have you going deeper into the throttle to get up hills and etc... which is going to hurt your mpg...i think mating a DX trans to it and adopting some hypermilling techniques will net you better gains...but ---- it, you got it there throw the bitch in and prove us wrong :-P GL

I've been doing some research and I think I'm going to see about adding a TD04 9B or 9G I can't remember which, or a GT12. I suppose whatever I can find cheap that is in good working order. The idea I have is any boost at crusing speed, about 2000rpm or so, will increase the effective CR. Tuning will be a key point, and I'm not sure if either of those two turbos will be building enough boost to amount to anything.
All I have to do is change out the driver's side half shaft and I'm ready for the strip tomorrow if it doesn't rain. I'll let everyone know how it does.

$125 Shipped. Might be worth it instead of tring to salvage what I have. I didn't realize that stuff was so cheap. Thought I'd share.

Re: Flash944's attack on a 50 MPG beater
add a egr valve and run some lean ratios in boost at low rpm like modern 1.8t vw's do.. i dont know how lean but i know its not the normal 12:1 or so 13.5
jd should know more about this kind of stuff as long as you have no knock and egt stay safe
