well i killed my 3sge gen 2 and im not so sure what i want to do. I've seen some hi-comp 4agze's where the SC has simply been put on a 4age. what my idea was, was bolting a SC14 onto a 3sge to give it some more grunt, and upgrade the injectors and run a apexi s-afc and keep boost to a minimum.

Think this would work?

im only thinkin of this if i cant find a 3sgte cheap enough.

Sc14 off a 1ggze?? They are extreamly rare, I also found this

(Stock boost is regulated to about 0.7 bar, and the units are normally driven at 1.25 times crank speed)

If you find a sc14 Keep us updated it sounds interesting

hmmm how about a Sc12? i knoe they produce les,s BUT what if i drove it to push say 12/14psi, how would that go? just want something different and if i can't get a cheap enough 3sgte its a good way for some more power in my opinion. Problem is, i can't even find a 3sge atm

sc14s are easy to find, got 2 avail now... $500
12 will be too small for 2ltr

You think that they're too small for a 2.0l... same here and thats what I told the guy that came thru work claiming to be fitting one to his 3.8l Commonwhore and claiming to be fitting a 17lb pulley kit to it!!! I thought of doing this in my younger days with my first Celica but never really eventuated. Would be a mint engine... didnt they do this to the Altezza?

Liloss if you ever get this going let me know how it goes i am wanting to do a 3sgze as well. turbos are so 80's

by **evil_si** » Tue Apr 12, 2005 11:30 pm

there is an sc14 on trade me at the moment last i checked it was at just over $100

by **Zero_Cool** » Tue Apr 12, 2005 11:40 pm

any one know how strong the 3sge engine is? could you run like 10ish psi on standard?

wat i meant is everyone has a turbo (3sgte). having a 3sgze will be alot more original

If when you say 'original' you mean 'slower' than yes, you are correct.

Remember, a supercharged engine running 10 psi will be less powerful than a turbo charged engine running 10 psi.

Due to D.P.B. loss.

Aaah, I mean parasitic loss.

begining original isnt' about going fast. If you said to somebody and said "i have a turbo 3sge" then they say "o ok thats not very interesting" but if you said "i have a 3sgze then they probably go oo thats interestign!"

see my point?

Yep thats what i said. It would be wicked.
Its something different. Very cool.

SC12 would definatly be too small. Considering that it's a roots type S/C, which provides flow at lower RPM, but becomes a bit of a restriction at lower RPM, which is a characteristic of a 4AGZE. The results would be amplified on a 3SGE as the CFM rate at higher RPM would be greater than the 1.6l 4AG engine at higher RPM, thus it would have even greater restrictive properties on a 3SGE.
SC14 might be the way to go, but if you're not planning on doing any internal modification to the bottom end, then 6psi would probably be your absolute limit. You may find that it's not worth it.

There's other things to think about too, like where to mount it and all the pipework thats involved. Seeing as roots type S/C's have a rather low adiebatic rate (30%-40%), you'd want an intercooler in there. You'd probably have to go for an aftermarket ECU as well.

I think if your initial motivation for this is that you can't find a turbo motor you can afford, then you won't be able to afford this either, it will end up being a rather costly exercise for something that may not live up to your expectations.

It has already been done by a guy in Wanganui. Don't know if he went with the 12 or 14 though. Fitted it all to his SW20 rally car and embarrassed a hell of a lot of 4WD cars. Would have been about 4 years ago that I saw it.

by **Adamal** » Wed Apr 13, 2005 10:30 pm

An SW20 RALLY car?!?! As in an SW20 on DIRT?!

If so, I'd say the driver probably has more amazing skills than some sort of power advantage over the 4WD cars!

by **Zero_Cool** » Wed Apr 13, 2005 10:32 pm

i'd have to agree SW20 on dirt is nuts SW20 in wet is somtimes crazy enough

by **Liloss** » Thu Apr 14, 2005 8:30 pm

well its not the money that is worrying me. i already have a s-afc that i was going to run on the mr2. the Sc14 i can afford. custom bracket and pipe fabbing i can have done for free. Also it's different. i dont want a turbo car, i know they are fast but theres so many and they are so common now. so yeh, anyone know of a 3sge for sale?
