lol seriously, i've put nitrous on a car in 30min.

Zex kit owns, only problem is, the bottle's always empty when u need it. And around here it's 42.50 to fill it, i'm sure it's more out west.

Turbo kit is a little more involved but thats where the power is at, and it's awsome knowing that every time u step on the pedal, power's there if u want it.

 

Goat and Ryan were cool to send me links and instructions on boosting a while back. I still have the info, but don't know if I can get that involved just yet.

30min.... lol I'm gonna do some research on the Zex kit. o:

Edit: I know it would be cheaper to piece a turbo together, but if you were to buy a kit, which one would you guys get?

 

If I bought a turbo kit I'd go with edelbrock.

 

I lol'd at this thread, too.

BTW, CX/VX trans = AOK MPG FTW! Perhaps that transmission swap would be easier than swapping the D15z1? Just using that trans will turn your ride into the somewhat lesser-performing golf kart while boosting your mpg's. Right Patrick? I got 44mpg with a D15b7 by using that trans. Once you get used to it, it can be a lot of fun with a high-revving engine.

OH, Hi guys!

 

agreed. if i was going to buy a kit i'd go edelbrock. It's all there, they have the most complete & well thought out kit on the market.

oh & .. hi :hay: Jafro

vx trans is the worst peice of engineering ever to disgrace a honda. Oh wait, you live in VA. Drive that car in the mountains and I guarantee you'll be in 2nd or 3rd gear 90% of the time. I think Si trans + VX 5th = ultimate win.

 

Yes. Yes you will be in 2nd or 3rd gear most of the time in the mountains. I used to go skiing all the time in my Honda, and having to downshift for a long pull occasionally was less than a problem to me. It's the long highway 5th gear pulls that make it worthwhile.

5th gear at 55mph is around 1800 rpms. Meaning that cruising at highway speeds, your car is barely burning any fuel, thus the great mileage. You WILL NOT BE ABLE TO PASS ANYONE in any gear BUT second, which will take you to 84mph at red line with a dx motor and ecu. I know for a fact that at 7000 rpms in 3rd gear, you would be traveling 135mph, IF you can make enough power to overcome the wind resistance. I did it on a dyno, so that's how I know.

Learning to drive with this transmission on any variety of torqueless d-series engines can be challenging, but once you figure out that if you keep it wound up (like an early S2000) to make enough power to get out of its own way, it's extremely driveable, and in some cases even advantageous due to the lack of shifting needed. It's sort-of a 1-2-5 kind of setup, but I still used 3 & 4 anyway.

Engineering catastrophe or not, it's actually got great purpose when big auto is still only cranking 30 mpg out of new cars. The cx and vx trannies are almost the same. The engines are very different. The red line on the cx is 1900 rpms less than any 16-valve honda engine, and surprisingly, both of the 1.5L 8-valve engines make a lot of low-end torque in comparison to their 16v counterparts, which allowed these transmissions to work well. That's why it's like driving a car in Gran Tourismo after you've played with (and screwed up) the gear ratios. The advantage of the screwed up gear ratios = really flippin' awesome gas mileage.

 

Having an Si that as you know, loves to rev, I find myself not shifting over 2300 during city driving, and I get into 5th gear as soon as I can.

So many options. Either keep the d15b vtec with Si tranny and have the 5th gear swap, or just go with the vx motor and tranny straight out. Either way, boost and juice are options, and I still wanna play mpg-whore with the car.

 

Driving like this does worse things to your mileage than just having some usable power, IMO. Believe me, I drove a stock vx drivetrain for over 4 years, and I learned how to make it go... basically just wail on it in 1st-3rd gear, skip 4th and put it in 5th ONLY on flat or downhill highway. I didn't see a noticeable drop in mileage going from a stock vx setup to a stock b16a setup... mainly because I could shift at a reasonable rpm without holding up the old-folks busses. :hsugh: :edit: I also made an effort to keep the highway speeds legal, which I generally don't do.

Granted, I live at over a mile elevation, and frequently drive up to 10k feet going to WP or Copper, so I guess my experience should be taken with a grain of salt h:
