[Dr_Tweak]

Engine and parts...















Work on the tune-up and reseal



























Pulling the old engine

























Cleaning









Wiring















Flywheel and clutch kit







GT mount parts









Installing the 3S

[njccmd2002]

how secure are those bolts.

[Ted95]

sweeeetttt that will be me in a few weeks or so

[rave2n]

loving it, specially with so many pics! Can't wait to get it done myself. Great job, looking forward to more.

[BriinumsBo]

awesome! should have been mated to awd platform though did you really pull out all wiring? was it direct swap or you had to fiddle with all that junk shpaghetti?
great project

[95st-celica]

the bolts for the GT mount are very secure...that is exactly how i did mine and it works great

SO tweak, what is the going rate you are charging these days for a swap?

lets say they provide the engine and all the parts, what are you charging for the install and wireing?

[Lil-Joe101]

Nice job, I should be calling within the next few months to schedule an appoinment for my baby. Again great job Doc.

[Dr_Tweak]

Ha yes, secure is an understatement, they are likely stronger than the factory GT setup. They go completely through the frame and are secured on each end by nuts with washers and lock-washers.

I'll let you know when I find out for sure, I'm trying to charge more accurately for swaps. I used to charge a flat right but it was just waaaay too low and didn't begin to represent the actual hours put into the project.

Nice post. Finally found a forum with alot of pictures. Im interested in the wiring involved. I know you have to have the 3sgte ecu, im guessing the motor came with that and the uncut harness? And please let us know a quote. I only live 8 hours away and i might have some work for you.

[Smaay]

excellent post and pictures! lets see the FMIC setup!

[Dr_Tweak]

celica74, that wiring job is normally $540, right now we have a special going on for $450, it is good until the end of the year.

Thank you all for your kind comments.

E153 axles:





Koyo radiator install











Dr Tweak cold air intake











Walbro fuel pump







On the ST you lose the cooling lines for the power steering, so we went ahead and installed a dedicated cooler for it.



Intercooler and piping ready to go

[Punch]

nice work doc...............

[mak5603]

Lookin GOOD!

[presure2]

looking good as always tweak!
like the zippys to hold the tubing in place!

[celica74]

My st doesnt have the cooler. Mine is a 94 so im guessing that come into play later on?

[Dr_Tweak]

The p/s cooler? That was added in because the cooling lines got eliminated in the GT mount swap. In reality it's waay overkill for power steering, but it was the smallest one that they had.

-Doc

[CeLiCa_ST]

nice work..
which tranny did u use?
can u explain how did u fix E153 axles?

[jcbass7]

Looking good Doc, I love seeing boxes of new parts.

[Dr_Tweak]

We used an E153 transmission, to make the axles work you need to use the MR2 inners and ST165 outters.

-Doc

[celica74]

i guess they dont call your the doctor for nothing ha

[Dr_Tweak]

LMAO how do you know my line?

[enderswift]

WHOA I recognize that trans cooler! and that battery! You got those at advance didn't you

I sell those alllll day long

and how about the mid shaft?? did u use mr2 mid shaft?

Yes, that's one piece with the inner on that side.

Sorry for not updating the thread, here are all the other pics of the swap, which is now complete.

Stainless fuel line:









Intercooler kit:











Throttle cable and cruise control



















3" Mandrel-bent Stainless Exhaust

[mak5603]

Looks great as always . Any way you could PM me a list of the Samco couplers/hoses you used? I need to begin purchasing mine.

[Dr_Tweak]

If you want to send me an email I'll get you a price on putting a complete package together for you. contact@tweakdperformance.com

[Johnnyny]

I normally dont like fmic setups but this one is beautiful!

[Stambo]

tweak are you willing to make me one of those stainless lines?

I have that same magnaflow muffler. Thing sounds amazing!

IIRC he sells them on his site.

[MOREFAST]

wow it took me forever to find this thread!! haha im headed down there to pick it up on Saturday. i cant wait, it has been forever since ive had her all to myself! tweak totally hooked it up!
hey tweak, what kind of engine management system do you think would go good with the 4th gen and my set up? and wat about a turbo manifold? cuz that factory one has to go !

[bccentaur3]

The turbine housing is casted together with the manifold. Only way to go, if you want an aftermarket manifold get one made for a 3rd gen and a ct20b, why stop there when you can upgrade turbo

de cat asap!

Yeap, we have most sized of fittings and lines in stock so just let me know what you need and we'll get you taken care of

The one-piece manifold/turbine housing is a very effective design, the only reason to change it would be to upgrade the turbo, as mentioned. For engine management, I would run an AEM F/IC up to around 400-500hp, beyond that a custom EMS setup would be needed, but that's a pretty lofty goal as it is

-Doc

[purplegt4]

which AC/PS lines were used?

well, the pressure hose from the steering rack to be specific.
stock ST power steering lines fit the 3s pump?

[Dr_Tweak]

Surprising enough it did fit, yes.

[purplegt4]

Nice.

AC lines too?

[Dr_Tweak]

A/C lines took a bit of careful bending, but with a little creativity they did indeed work. Be sure to set aside several hours of labor for the work on the a/c lines, it's a bit of trial and error and you don't want to overdo it

That's surprising.

I have the rhd connections from the 3sgte compressor. Don't know if they would hook up to my current AC lines.

Did you use any bending tools? or just bend (and hope it doesn't crease) method.

Hey Doc, you know i admire your work, question for you. why dont you clock the turbo down so you dont have pipes going up and over the manifold?

Sorry, I forgot one important part of that. You need to swap the "manifold" from the top of the 7A compressor over to the 3SGTE compressor, THEN the 7A lines will connect, with a little bending. We didn't have to use any tools for the bending work, you just need to go a little at a time and spread the bend over a longer distance so that they don't kink.

Hey Doc, you know i admire your work, question for you. why dont you clock the turbo down so you dont have pipes going up and over the manifold?

Back in the day we used to clock the turbos, but we stopped doing it for a number of reasons.

For one, getting a bracket made that will hold the wastegate actuator in the right place reliably takes an entire day of work (it's a lot of trial and error and most of you know how hard it is to take the turbo off a 3S).

You really don't gain much in terms of reducing the bends, especially the way that we route the piping now.

Fitting the intercooler piping between the downpipe and radiator fan is difficult or impossible if you have the factory downpipe (which we do).

Since the piping that goes past the manifold is on the hot side anyway, the intercooler does a great job of chilling the air and so temperature really isn't a concern.

Some of these things are contrary to what you may have heard from me in years past, but time and experience have mended my ways :-D The 90-degree coupling coming off the compressor outlet is simple, reliable, quick, and it works perfectly every time.

ah so THATS why no more clocked turbos! i noticed on prodigy's car first then a few other swaps. always forgot to ask ya.

Just tried to hook up the ac lines, they ended up rubbing against the berk downpipe.

Yes, you need to "adjust" them a little bit
