5s-fe to 3s-ge swap??? Options

[Rusty]

not 100% true
a Gen 3 3S-GE is from 1994 - 1997, a BEAMS is +1997. So both SS-II and SS-III had the same 3S-GE given which year

Also what you could do, is buy a LHD 3S-GE engine loom/harness from UK/Europe people (post a WTB here or search the uk ebay), saving you the trouble of converting it to LHD. Try to get a prefacelift/1996 as the UK/Europe had EGR on their 3S-GE afterwards.

I doubt you'd be able to run a 3S nicely with a 5S ecu...

Don't have a choice. I live in a state where all cars from 1996 or newer get scanned. 3S ECU=not scannable.

However, I have on my side some experience making cars run off different ECUs than expected. I just need the 5S ECU so that our emissions scanners see OBD2...

I thought the SS-III swas only available from 98-99...then again, I am still semi-noobish...

The 3S is smaller displacement and higher compression. The 5S ECU MIGHT run the 3S but it'll be throwing to many codes that there's no way your state will pass the car. Since your state scans the OBDII port, then you're better off to take the advice posted earlier and do a little work to your 5S or, if it's legal, do a V6 swap.

Celica projector cutoff:



As you can see, the light flicks up into oncoming traffic. The focal point of the light is in that cutoff, which is why the cutoff should be fixed. Granted, the bulk of the light isn't in the top corner so it's not shining directly in everyone's eyes do you can get away with halogen bulbs but HID's are significantly brighter and should always have the cutoff fixed. They're well worth it though.

what makes you think you have to go AWD with a 3S-GTE swap? its just the engine. not the transmission.

im just giving my opinion about a 3S-GE swap. i dont think they are worth the money. id spend a little bit more for a 1MZ or GTE swap

Smaay's got a point about the AWD portion of your worries - most users that do swap out for the 3SGTE are still FF (front wheel drive).



If someone wanted to stay NA - the 3SGE swap is probably the best bang for the buck (even over the beams which will only gain you MAYBE 20HP for $1000 more for a clip).

Try rebuilding the 5S for around $500 to 190HP, I don't think its possible... or even doing the V6 swap without losing your mind trying to convert the engine harness, etc.

Plus - 3SGE would be a great base for a unique turbo swap in the future (most likely at a fraction of the cost of a full blown 3SGTE) with possibly decent comparisons to the 3SGTE.

I'm not bashing your opinions at all, I just happen to like this discussion.

[czwalga]

^ I agree with everything you said minus the 3sge being good for a turbo. Compression ratio is too high.


The 3sge swap is a great upgrade for a dieing 5sfe. More power, for about the same price.

Well - I wouldn't be running full boost if I were to eventually move to turbo. But I've seen plenty of successful High Compression/Low Boost set ups that work.

How many were on stock internal components? You'd be playing with fire on the stock stuff. I have a pretty high c/r on the rx7, and run a decent amount of boost, but the engine itself cost about the same as my entire rally car.

Granted its an MR2 - and he has a lot invested, but running stock internals. I haven't read through it lately but I think he was running crazy PSI on that set up too...

[KAOS]

Scratch that - I re-read it and it sounds like he's recently upgraded his internals... BUT; he did run stock internals for his first dyno of 317WHP @ 14PSI.

In less than a year the 3sge internals were out and he was using a 3sgte bottom end. There's a reason for that. It appears 16 psi it croaked, and says 14 psi would be a safe limit, but he doesnt know that for sure.

Like I said playing with fire. With that C/R I probably wouldnt run more than 6 psi... if I was afraid of blowing it up. I'm sure you can find people running high boost on stock internal engines, but that doesnt make it the norm or reliable.

Its probably a safe bet to lower the C/R - but he was also looking to make more HP.

I wasn't planning on running anything over 8 PSI on stock internals; I agree with you completely about it not being reliable, and I never said it was.

I just wanna tinker with a lil' bit o' boost.

I just know that I will have some options in the future once my 3SGE swap is complete. I'm keeping it NA for a while.

i was looking at the one but the guy wants to much for it!!! almost three grand wth is he smoking!!

not 100% true

so which gen 3s-ge would be better??

[njccmd2002]

i paid 2 grand for mine, and to swap invested another grand... so its not cheap

[m2736185]

IMO 3 grand might as well save up a little more for 3sgte unless you just prefer the NA route.

njccmd2002: How difficult was the rewiring for the beams swap?

[richee3]

Wiring for the BEAMS is easy.

[ricochet1490]

Or you can not deal with the wiring and do it the hard way lol - remove and replace!

[ricochet1490]

On a side note, I tend to agree with Czwalga and Kaos, a 3sge motor swap (non beams) is a worthy investment. When we're talking 40-50 hp increase for 500-700$, that really isn't bad. Think about it, we're discussing a group buy on some Colt Cams for the 5s. Change the cams = $400 , SAFC=$100, dyno time to tune it right = $50-100 So by the time you've done that, you've got $600 or so in a motor and only gained 35hp? Granted 35 hp off of one modification is very substantial, and there are obvious work advantages in not having to remove the engine etc etc..... but if you can do your own work, for around the same cost you can have ~10-20 more hp and it's bone stock....

Dyno305- I'm not going to say "hey, go read the stickies" - but I will say go to the my project section of this forum and just start reading. Read through Richee3's thread, read through czwalga's thread, read through greendemon's thread, read through S8S8's thread, read through my thread, read through anything and everything presure2 has written, read through everything that Batman722 has written and you'll learn more than you ever thought possible.

It took me hours and days to go through post by post.... and when you do you'll find out things that will answer your questions

i.e. 3sgte can mount to a 5sfe stock transmission, the S-54... infact all S-series engines can mount to the S-54. if you want a beefier tranny, get an e-153 (really only used with the 3sgte).
You'll find you don't have to remove the dash to do a motor swap, just the glove box and some small panels near the floor....

FINALLY- I am going to tell you that I'm getting the vibe that you are relatively new to modding cars. I came to this conclusion because you want to keep the automatic etc. So i'm going to assume that if you want to do a motor swap, you'll end up paying someone else to do it. And if you are going to pay someone else to do it, it's going to be cheaper to swap out cams and get a tune, than to swap out a whole motor because it all comes down to labor labor labor.

So I would recommend to you, unless you have all kinds of experience here, to start with the cams, we have a 400$ group buy of the best cams for the 5s in the works, and you should see what that does for you. IMO(in my opinion) that's the best thing you could do for yourself..... right now that is.
