Supercharging my 3SGE (JDM)

[GTRJDM]

Hey guys long time no post
As you probley no im from newzealand and over here the motors are all JDM.

Anyway ive just purchesed a fully rebuilt 1st gen 3sge JDM motor with only 20.000km on the motor when it was rebuilt anyway

Anyway What Im thinking of doing is Supercharging it. I no so many people say that doing this to a FE or turboing charging a FE is a bad idea.

But would Running a Supercharger on a 1st gen 3sge jdm which is fully rebuilt and is in top condition (not yet in car) have many problems. I was thinking about putting and fabrucation the mr2s 4agze superchager to my 3sge engine as this supercharger was made for a 1.6liter so it shoulded put too much stran on the 3sge. what do you guys think ??

Anyway I would really like to do this even more so than turbocharging it I wouldnt run any higher than probley 8psi eather way.

So can you tell me some good superchargers which Could work ?

What needs to be done to safer....ley SC this motor eg i was thinking a thicking head gascet to lower the compression would be needed ??

What other things would be a good idea to try and do before I put the S.C on the engine ?

btw my motor has also been funny ballanced all pistions rings and pistions etc are new all bearing etc new other parts etc.

And other mods which i dont wanna go into detail about now.

Anyway tell me what you guys think.

P.S why does everybody talk about SC or Turbo charging a 3SFE wouldnt the 3SGE be the minamin requriment ??

thanks guys

well let me recomend that you try to find a SC12 or SC14 supercharger those come on the AE92 4A-GZE and the Previa Supercharged 2RZ-FZE they are larger superchargers & flow more. also I would upgrade the injectors to the ST165 3S-GTE 440cc injectors. You are going to have to custom make a manifold for it. I think it's a good idea to go S/C but I think it's way more expensive in fabrication than a turbo project.

it would be a hell of a lot harder to fab up, but the fact that a supercharger doesnt have to spool kicks ass

there is a compressor-style SC designed for the camry's 5s-fe. this could be adapted (or possibly just bolted on)to work with the 3s-ge...... if you have a spare $3400

Ok Was talking to my mate who is helping me do the swap and the forceced induction swap

He had a look at my 3sge engine thats in my car now and said that it shouldnt be too hard to do it he knows how to fabrekate pipeing etc.

One problem we did have was weather the supercharger would fit by the altenater belt etc.

Im hopeing that the SC12 in the toyota lineup being a rather small superchager will bolt and fit there nicely under the hod.

to do this im going to have to move my airfilter and airflow meter down the front of the car by the radiation (on the out side but hidden by my front bumber kit) have pipeing running from that to the supercahger which is drivin of the fan belt up by the alternation then some how have pipeing running from there into the engine trying to somehow avoid the pipeing running over the exzaust manifolds and other hot stuff etc

another thing is im new to superchagers is it tru they dont use intercoolers ? thats what this guy said is it possable to use an intercooler if you really want cold air into the engine ??
post your knowlege
cheers

P.S im talking supercargers cant and dont have blowoff vavles lol

Hey jermey a Problem i have jsut thought of is this however.
how do i over come the problem when the MAP sensor reads say 8psi (sc12) of positive air engery entering it ??

somebody said this might be a problem?

[GTRJDM]

im also guessing that the superchager SC12 because it makes 8psi stock on the 4agze it would probley make 5 -4 psi ? on the 3sge due to it being a larger engine ??

which in that case im guessing it could probley run on stock compression ratios and head gaskets.

but I dont relly no yet

also does a superchager need a intercooler somebody said it didi somebody said they dont and said to me in quote "look at drag cars they just suck the air strait down into the engine do you see an intercooler ther on there superchargers"

that was his words so now im lost with that simple part

[ToyGTR]

I wouldnt bother with a SC12, just look for a SC14. Just watch out on trademe etc cos they pop up from time to time...

[buzzbomber87gts]

if you have a/c put the supercharger in place of the a/c compressor

[GTRJDM]

Wow thats a bloody Great Idea. My A/C is stuffed anyway.
Also thanks TOYGtr for the input on the sizes.

Anyway ive still got a probley but somebody told me the MAP sensor wont like reading 8psi etc postive pressure going in to it.

Is this tru Im still thinking about running the SC12 just because i dont no if my motor will handle the SC14 with out doing mayjor mayjor mods. what do you guys think ive only got brand new stock pistions but they have been coated with something forget what it is now but yea everything else is top noch good condition. So i was think the sc12 would be great but if it can handle a SC14 that be cool too.

Im guessing if i put the sc14 on maybe even if i put the sc12 on I would have to lower the compreesion with a lower comp metal head gasket ??

what do you guys think could i get away (cos of the condition of my engine (not meaing to brag lol) with the standard comp ratio levels with sayt the sc12 or will i need to do something about that.

finnaly someone told me superchagers (toyota ones) use Intercoolers but then somebody else said they dident and demonstrated to me how a drag car superchager works stateing that they dont need an interncooler so now im lost do they or dont they.

As i said ive got someone who is very good wif toyota engine (he rebuilds the supra engines) helping me do this project.

Thanks for all the help guys I will take photos when i do they engine sawp and bolt the chager onto my new engine so you guys can see how i did it and if it works with ok running somebody else might like to try this too.

by the way everythign else on my motor has been rebuilt and replaced but however some parts are only stock replacment parts others are coated and other parts are better quality.

+ this motor is getting a port+polish etc

[MIGHTY]

Would this MOD be hard to do??? how much would it cost ??

[GTRJDM]

Well so far its seems to be easy ive got all the parts but still thinking weatther to use the SC14 over the SC12 in the toyota supercharger lineup

part from the im working on the fabrakitions

And trying to do the maths on the compression weather it needs to me lowerd and to what etc

[ToyGTR]

The SC12 was actually designed for like a 1.3 litre motor...thats why the SC14 is a good upgrade for the 4AGZE. Yes the superchargers do use intercoolers, look at the AE101 GTZ - has a top mount air-to-air intercooler.
