  • would like to know how I might be able to make a 2004 Malibu engine more "efficient"? I.e. some more power without guzzling more gas.

    Suggestions, thoughts?
  • I have a 2004 Dakota. I am limited to Poweraid and Helix Power for my options for a throttle body spacer. Any suggestions for which one may be better? Two totally different designs.

    Why are you using a throttle body spacer?

    other than slamming the warranty, I mean. I've tested lots of gadgets like TB spaces, velocity stacks, etc, and only MINOR gains have showed at ridiculous rpms (like 2 hp at 8,000 prm)....hardly worth the cost, and the warranty hassles.

    Also spacers suggest to me that something is not actually made to fit and work properly. The spacers can create obstruction or other flow problems into the manifold.

    I drive a 94 Toyota Paseo, and its hard if not downright impossible to find any aftermarket parts for it. Recently I saw a Tercel of the same generation (1991 to 1995) with euro tailights. I would like to switch out the trunk and tailight assemblyon my car in favor of the tercel so i could have the euros, but i was wondering if anyone knows offhand or has the measurements for the trunk on a tercel of that yearso I can see if that is a feasible solution.

    I have a 1988 Toyota Corolla SR5 Sll-trac with the 1.6L 4A-FE engine. I want to rip that engine out and put in a bigger one from a different toyota from about the same year, something more powerful, but I'm not sure what would fit. Of course when you ask Toyota themselves they say "we don't reccomend modifying our cars... blah blah blah." Do any of you have any idea, or know where I can go to find out?
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,681
    You need to take a trip to the wrecking yard I think (maybe a Pick a Part type operation) and bring some brown wrapping paper and a magic marker and make a pattern of the tercel taillights (which will probably be removed from the wreck anyway, so it'll be easy). If the Tercel assembly is larger than maybe you can get away with some careful cutting to make them fit the Paseo (a handy tool for this might be a "nibbler") but if the Tercel assembly is smaller that sounds like a lot of work, as in welding.
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,681
    You might check to see if Toyota actually upgraded the All-Trac engine at any point; if they didn't, I don't think such a conversion is worth the trouble--you'd be better off modifying your engine or at least doing an overhaul on it and then a turbo kit if you can find one. But trying to stuff an engine that was never meant for that car could be a hell of a lot of work on an AWD car especially.

    Me and my wife just decided on buying a crysler crossfire and I am looking for more speed and not wanting to pay the extra $15000 for the srt. I have looked and looked on the web and found nothing. Any suggestions apreciated.
    Thanks
  • I recently purchased a 1989 GMC R2500 Suburban with a 454. Most of my experience is with classic Mopar vehicles. That said, I would like to get some suggestions on what I can do to get this bad boy running at its best. I noticed that it only has a 2 barrel (fuel injected) carburetor. Is this the best way to go (again, bear with my in-experience)? I also noticed that it has single exhaust... what an injustice :-) What type of manifolds/exhaust performs best with this type of engine?

    Oh, any other performance enhancing suggestions would be greatly welcomed.
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,681
    I always like to think of the intake/engine/exhaust as "one long tube". So if you do something to one end, you need to be thinking about the other end. I think dual exhausts (with the proper exhaust headers) would be a good idea on the "back end", and you might check and see if intake vendors like Edelbrock make anything that would work on your '89. You have the TBI injection type, I think and I don't know how much you can do with them. Also you don't want to run into smog hassles or do you care?

    How fast you want to go depends on how much you want to spend. Simplest mods are getting more air into the engine (such as cold air intakes or short ram intakes) and a free flowing exhaust. Probably the stock ignition is good enough for your needs.

    Here are some good books on seriously modifying the 454:

    http://lib1.store.vip.sc5.yahoo.com/lib/rodi/guide.hpbooks.app1.html

    But I think a custom air filter system and dual exhausts would be a good first step for you.

    You should post this question in our Maintenance & Repair Board. Look for the topics called "Technical Questions" or "No Starts".

    this is a big subject....I think if you are fishing for ideas you'd find these books very helpful---they'll give you some gameplan.

  • I just bought one and have the same problem. Cant find anything on the net.. there is however an option with Powerchip. They can chip the engine which gets your about 15 more Kw and 40ish more Nm. If you find anything else, please let me know
