Mr Revhead[RL] Posted July 1, 2005 Report Share Posted July 1, 2005 the difference between the face lift s/t and pre face lift is easy to see in that article. they mention it, look at the face that meets the head. b/t are different again. bigger. can't remember the exact size but i have it somewhere. that price before included freight and my take! i have to make SOME $$$ :thumbsup: Quote Link to comment Share on other sites More sharing options...

Felix Posted July 1, 2005 Report Share Posted July 1, 2005 surely must be cheaper to buy a complete 20v setup, than to convert the orig engine to quad throttle bodies, plus the cost of an aftermarket computer. they can fit in a ke17: Quote Link to comment Share on other sites More sharing options...
Felix Posted July 1, 2005 Report Share Posted July 1, 2005 these guys are giving them away then Quote Link to comment Share on other sites More sharing options...
demuire Posted July 1, 2005 Author Report Share Posted July 1, 2005 Jamie: 4AGE has injectors in the head, not on the manifold. Doug: Apart from being harder to fit a 20v in (mostly due to the dizzy, and also due to the water piping), the torque curves on the 20v are also a fair bit different, as far as I've heard. The 20v's are a bit like the Honda VTECs, they make good power, but they make it all in a fairly narrow powerband. I've been told that the 16v is a far more flexible engine. That said, it's all stuff I've heard, nothing I know as a fact. Anyways, to drop the 20v in, you'd have to convert to either DLI or do a dodgy and move the dizzy up front (like Acoustic had on his 20v for a little while). Or mount the engine further forward so that the dizzy clears. And after all of that work, you'll have a stock 20v. Aftermarket computer on the engine would give a hell of a lot more options, not only would you be able to get your engine running *perfectly* for it's current setup (quads or no quads), but you can run bigger cams etc etc etc, things you can't do with the standard computer. Putting big cams in a 20v is hard, because of the VVTi. Putting adjustable cam gears is also hard, again because of the VVTi. The 20v engine is a better engine in some ways to the 16v, but it makes it harder to make it go any faster... Quote Link to comment Share on other sites More sharing options...
Super Jamie Posted July 1, 2005 Report Share Posted July 1, 2005 20v is good engine for turbo only if you listen to bill sherwood if you want na, go 16v smallport Quote Link to comment Share on other sites More sharing options...
demuire Posted July 1, 2005 Author Report Share Posted July 1, 2005 Actually, when you think about it... Throttle bodies aren't very complex are they? It's a block of alloy, with a hole in it, and something to open or close the hole (butterfly, or slide etc). Hmm. There must be more to it, I must be missing something...

Super Jamie Posted July 1, 2005 Report Share Posted July 1, 2005 don't forget TPS, which is essentially a variable resistor Quote Link to comment Share on other sites More sharing options...
demuire Posted July 1, 2005 Author Report Share Posted July 1, 2005 (edited) Well, the TPS would link onto the linkages, and if I use anything non-Toyota I'll need to do this anyway... Or I could get an aftermarket TPS... :thumbsup: Haha, me and my dreams... Edited July 1, 2005 by demuire Quote Link to comment Share on other sites More sharing options...
demuire Posted July 1, 2005 Author Report Share Posted July 1, 2005 (edited) If you got an aftermarket computer you'd do away with the MAP sensor anyway. Just run off the O2 and CAS. The MAP sensor is the main reason why it's hard to put quads on a 4AGE, there is no good place to get manifold vacuum...

Mr Revhead[RL] Posted July 1, 2005 Report Share Posted July 1, 2005 theres a perfect place for getting a map sensor reading. the b/t is map...... on the silvertop that kidney shaped fuel rail looking thing isnt a fuel rail. its a vacuum balance chamber.... just right for map reading :thumbsup: Quote Link to comment Share on other sites More sharing options...
Felix Posted July 1, 2005 Report Share Posted July 1, 2005 (edited) i would think you would want to run a MAP sensor. otherwise how is the ECU to know what sort of load the engine is running at? Edited July 1, 2005 by Felix Quote Link to comment Share on other sites More sharing options...
TRD ke70 Posted July 1, 2005 Report Share Posted July 1, 2005 our throttle bodies had no problems with get a signal for the MAP. Quote Link to comment Share on other sites More sharing options...
