I' ve been considering this as my build progresses and it's something I want to do after I get the car on the road.... but something I want to do nonetheless. I don't want a terribly high investment but 200+ WHP would be a great feeling.... and this is where I'm looking for expertise outside of mine....
Internals are remaining factory Looking at going with a supercharger and I don't really like how "cluttered" the engine bay looks with a turbo .... it also isn't as "peaky" and should be more smooth to the power My initial thought is that I want to keep the stock ECU so I'm assuming I have to stay at about 5psi or so for this to happen? I'm frankly not sure what the stock beams ecu can handle as far as boost is concerned. Any thoughts? What are my best tuning options? I want something that is tunable and the toyota ecu not be able to change it (if that makes sense... these things are smart) I want to keep the CR stock as well. With a proper tune, and the low boost numbers it shouldn't be a big deal I don't think, just gotta watch for knock Keeping the boost low like that, I'm HOPING that the stock fuel pump is adequate to handle the increased load... More importantly the injector size of the BEAMS has been debated. The books say 340 cc while the bench test hat the guy did on Daniels injectors reported 400 cc flat. If they are 400cc, I don't think I'll need to upgrade those either... but again, I just don't know. My biggest questions at the moment are involved around ECU and the tuning, but any and all help would be appreciated -------------------- |

The supercharger idea seems interesting to me, because both the BEAMS and the SC work best at high RPM. Seems like a better match than turbo. May run into mounting issues, since the 3S-GE is tilted back slightly.

May run into mounting issues, since the 3S-GE is tilted back slightly. Should be plenty of space behind the block.... But I agree, the SC may be better. One reason is the lack of turbo exhaust manifolds, or even aftermarket ex manifolds period for the BEAMS. Just depends on if you could adapt cheaper parts that work IF your goals are low amounts of boost. I've been trying to acquire an old GM supercharger off of an old buick regal to see if there is any way to dis assemble and mount it up... namely because those parts are plentiful and one could reasonably get one for cheap if you knew where to look -------------------- |

A supercharger isn't better or safer than a turbo. Turbo lets you do much more than a supercharger. If you want the turbo to work at high RPMs only, you can put on a GT35R. If you want to compliment the BEAMS, you can do so with a smaller turbo, have it give the engine a little torque before VVT-i then a huge boost in power when the VVT-i goes on.
The supercharger will take away low-end power in exchange for a tiny bit (compared to a turbo) high-end power... And like I said it's not "safer". It would take a lot more fabrication than a turbo. If you wanted, you could literally weld a flange at the collector of the stock header and put the turbo there. You could cut your stock manifold flange and adapt it to a previous-gen stainless steel manifold (like the 2nd gen 3sgte tubular manifold)... etc etc. -------------------- 1993 Celica GT Coupe - sold

Keep the stock header and 4-2 and 2-1 collector of the stock beams b-pipe, and then put your turbo and turbo flange etc etc under the car. protect it with an underbelly pan like vincent doggy and culpable sell, or make your own.. or put it afte the 4-2 collector and have in the front but down and out of the way towards the front before subframe gets in the way.... Syaoran, nice idea... But also good idea about taking a gen two manifold and adapting the beams mounting plate... I've got all the welders needed for that.... I just ate how it looks. Afte the collector feels like it would be a "cleaner" look. This post has been edited by ricochet1490: Jul 24, 2012 - 11:44 AM -------------------- |
