DIY: how to make 3sgte gen4 fit into toyota mr2 Turbo sw20

[@willypor3924]

four years and this man is still a blessing thank you

[@Godscountry2732]

Great job. I really enjoyed the video. A little tip for your viewers, make sure you use high-grade rubber replacement hose lines, as well as high-grade metal, braided, AN fittings, etc Do not reuse old vacuum, fuel, coolant, brake, oil lines,etc.lines unless they are as new condition, it's just not worth the risk. High-grade fuel injection hose and fuel injection clamps work really well for all the rubber hoses that need to be replaced. The fuel injection clamps have a smooth band that doesn't cut into the hose like the common screw clamps. You can also purchase similar type smooth band hose clamps for coolant hoses,.They look good and last forever. Just make sure the hose is rated for the fuel pressure and or vacuum source your replacing, as some of the rubber hose sold aren't rated for high pressure and or oil contaminants, coolant, fuel vapors. They will fail, usually when you're going to your best friend's wedding or while you're trapping 145 mph at the drag strip "on fire with no brakes". Check the hoses rating, application if it is going to be used for critical vehicle control, like a vacuum booster for your brakes. If it collapses or breaks down from fuel, oil vapors, coolant, you lose your brake assist or ?. Also, you plan to run E85 or other fuels, make sure the lines, pumps, pickups, fuel tanks are rated for the fuel you intend to use. And use high flow, high filtration filters, that you can clean. Place them before and after the pumps when you can. You save the pumps, regulators, and injectors from ingesting dirt, metal, plastic. I recommend not using Chinese AN fittings, fuel cells pumps unless they have a very high rating and backing from an American supplier. Buyer beware, use at your own risk. The fuel cells can crack as most, not all Asian, etc import manufactures use a low-grade aluminum, cheap aluminum wire.,fittings, etc Buy American, Japanese, European or ? when you can. A leaking AN fitting, fuel line, fuel cell, brake line, etc can cost you or life and your car. That's my 2 cents, hope it helps.

God bless this noble man!!!!

[@GrenadeMotorsports]

Thanks bud. I've V6'ed several SW20 cars, but this gen4 was new to me. I bought the engine first and wasn't sure about it, but after watching this- it's a piece of cake! Thanks again.

[@wolfie083188]

you are the man!!!!!! I was wondering how to delete the heater lines and where the vacuum goes. you saved my life. I'm finishing my swap now. I just reconnected the clutch slave. about to flush my cooling system and install a new radiator + fans. also thanks for mentioning the intercooler wires. I had no idea where to connect it ! again, thanks a lot!!!!

[@BobPham]

No PrObLeM 😀

[@svang1991]

This guy is a legend. Thanks, Bob.

[@Mad_Dirty]

Proper clutch setup for reusing the S54 would be to order a hybrid kit from South Bend Clutch. It uses a E153 disk, so that you maximize the surface area (S54 disk is smaller in diameter than the E153), but it the uses the S54 center, so the splines are correct.

[@negativeindustrial]

Mad Dirty ACT makes one as well. I’ve had the same hybrid stage 2 setup in my swapped ‘94 Celica for twelve years. Still hooks right up.

[@kingdavid2018]

Great content sir. If you ever tackle a 2gr-fe swap, please do a detailed video as well! Keep it up 👍

[@mr2scroll538]

thank you so much like really this means a lot , you guys on facbook always help so much with info all the time , keep vids coming sw20 forever thanks again bro , know i just gotta save up for motor , i was thinking of just buy all the parts need first then getting motor

[@BobPham]

No PrObLeM 😀. Let me know if U need any gen4 stuff.

[@jakobe75]

this is great info. I am just learning about this swap for my 94. Thanks for laying it all out.

[@miguelg1017]

This makes me want to get rid of my gen 2 and get a gen 4. Good work man

[@BobPham]

Yea. It's so much cleaner and no oil leak. It runs super smooth and C.O.P. Not more distributer

[@AssassinRain]

Hey bob pham would you rather own a gen 4 or gen 5

[@AssassinRain]

So I know this was back then so would you rather mod a gen 4 or gen 5 now?

[@bedwarsprogamig]

Pleasant night I would like to get some information where can I buy my full kit seal for that 3s turbo engine

[@bitingantz]

Hi Bob, for the j hook engine mount on the passenger side is the turbo model hook different from the NA. I have a NA hook but it does not seal the timing cover area on a gen 5 very well.

[@Chris-fj9ir]

Sir...my sw20 na came with the 3sge motor... will this info still apply.? . Like the ac compressor And changing fuel pump etc..

[@salscrofano7870]

Great video I’m buying an sw20 2moro and I’m researching swaps now but can’t decide between kswap or 4th gen 3s-gte but kinda wanna stay brand specific any info will help

[@ellyholford1785]

love the knowledge brother i just bought a mr2 1991... and i wanna put in a gen 4 engine

[@jsm775]

Where is the best price to get gen 4 motors

[@lmenzol]

Do have any videos on mating the engine harness to the body harness?

[@guy_with_a_car]

What was there before where you now put the alternator? Did you delete something?

[@AllanDelosReyes]

Can an NA trans will work with the Gen4?

[@angelamaral3934]

What goes into the line right next to the lower heater core line ?

[@mtang65]

To those who runs without a CAT, does the exhaust fume manageable when comes to a stop or idling?

[@mk2mister2]

I ran it without a cat for a while and when you are at a stop light idling with the t tops off, the fumes are pretty strong. Subsequently, I went with catted downpipe, and never looked back.

[@TheLansang]

Hi Bob, do you use the Gen2 3wire oxygen sensor or did you use the Caldina 4wire oxygen sensor?

[@ady-bdavid1173]

I know this is an old post, but I have a question. Would it be worth while getting a new turbo manifold fabricated?

[@rolldog82]

Whats the difference between aw11 and sw20 or similar swap?

[@frankgrace3530]

Will the GEN3 water neck and alternator bracket work on this engine?

[@JC-slammedaf]

Awesome videos man! Whats a general estimate of what it costs you to swap a gen 4 and have it running in the aw20? Thanks

[@VictorRamirez-rg4pg]

How much is all this ? If I had a shell of a 91 mr2 n/a no turbo ?

[@Cj93mr2]

i am about to start my 2ed gen NA to 2ed gen JDM turbo any big tips?

[@gerhardlebreton1542]

hi Bob im from south africa where did you say you get your parts from like thermostats ect ?? its really difficult to find the right parts in sa

[@JMRWIGGLES]

does a 3sgt water outlet fit a 3sge?

[@rickitlor]

Bob which oil dip stick did you use..

[@BobPham]

Thai Lor one that came with the engine. This case it’s a gen4

[@ericcindycrowder7482]

I recommend the A/C delete! Especially if you live in Texas or Florida

[@negativeindustrial]

ERIC & CINDY Crowder I’ve always run my Celicas and MR2s in Texas without AC. That’s what sunroofs and T-Tops are for

[@sanfordrhudy774]

Awesome man! Could this engine work in a MK1 n/a MR2 with its auto transmission? See, I'm an older guy that been thru bunch of back surgeries(bad ones). And due to messed-up nerves,don't have enough use of my clutch leg. Or, would I be better off just doing a junkyard DIY turbo kit for it? Never been around turbochargers, but, back in the 80's and 90's I used DumpLoads of nitrous in my 69 Chevelle.

[@morgandillon4019]

Im fairly confident people have done this swap in an mk1, it isn't nearly as straight forward and you would certainly need at least an s54 although I would recommend an e153. Diy turbo kit on an AW11 would likely cost more than the engine swap itself.

[@andriybandera5749]

Do you have any idea how I can wire a 3sgte 3rd gen in a 95 Celica ST? It plugs in, dash lights up. No fire.. I assume its something at the relay end of the plug I need to change.

[@mitchelltyner5670]

I've been thinking of doing a JDM engine swap for my 93 N/A, I got a 91 turbo parts car but I wanted something with more power stock so was thinking about the gen 4 because of COP and it doesn't leak as bad. My question is this, what computer do you use on it? The one that came with the engine from the SUV in Japan or a different one? If I can remember rightly, one of the big power killers for the 2nd gen 3sgte in the US cars was the programming on the computer right?

[@tommyhajimoto6968]

How are you modifying the water neck and do I need that charging cannister for the wastegate? I took mine off and just using a mbc.

[@BobPham]

Tommy Hajimoto I have my guy weld me that custom water neck. That gold diaphragm can be deleted. Just cap off at the wg

[@tommyhajimoto6968]

Bob Pham thanks

[@Eric-zy7fm]

Nice video. How did you weld the stainless steel to the gen 4 downpipe?

[@BobPham]

Eric Costa Murta thanks. What ss to dp? I don't understand your question

[@nel2556]

Hey man, I am an amateur and I found an mr2 project car for pretty cheap that comes with a rebuilt 3sgte, brand new pistons, rings, bearings, valves, all the seals and gaskets are new on the engine. It also has a brand new gt35r turbo, 45mm wastegate, also have the stock CT26 turbo. Was wondering how much it would be worth and how much work I would need to put into it. Thanks

[@sammiemodeste4291]

could this engine work on a toyota levin bz-r?

[@rossco5995]

You mentioned you rebuilt the alternator. Do you have bearing numbers by chance?

[@BobPham]

Ross Henry no sir. I brought mine to my local alternator rebuild place and told them I want them to put the amp to 100-120. The max that the casing can hold

[@neftali6903]

In the middle of my swap right now Bob. Could I re-use 5sfe A/C tensioner bracket on the 4th gen or does it have to be from the 2nd gen 3sgte?

[@BobPham]

Taly Victor @2:10

[@dennisl4961]

also 3:15 Can you use the CT15 oem oil line into the CT26 turbo or i have to get custom oil line like yours?

[@TheStpeteboy]

How do you like that maxjax lift and why did you go for the ct26 instead of the ct20 or Ct15b? Thanks man!

[@BobPham]

I love the max jax. Perfect for mr2. :) I went with ct26 for high end tq and in theory can produce for power since the engine can rev up to 7000 rpm. My swap will have the billet 20b. My last video with ct15b made 308whp on 91 pump gas and run rich in the 10s afr

[@TheStpeteboy]

+Bob Pham I have another question! How do you make the boost gauge work with the gen 4? I thought the boost gauge was disable with gen 4 but in another video with an aftermarket gauge, it works! Thanks!

[@BobPham]

+Yod S u have to use aftermarket boost gate. U can't use the stock one cuz it runs off the gen2 ecu. For aftermarket just find any vacuum source.

[@antoinevanoostdam5331]

Hey looking for info how to hook up charcoal canister in my aw11 gen4 3sgte swap, where is the charcoal vsv on the gen4 ?

[@lmenzol]

Antoine Van Oostdam throw it away

[@olliereed5028]

what did you do with the power steering pump

[@BobPham]

ollie reed from the gen4? Trash!!

[@olliereed5028]

true, whats it like driving without it?

[@BobPham]

ollie reed it’s ok. A lot of mr2 don’t come with power steering. It’s not bad since the front end of mr2 is really light. If u go wider tires up front then it’s a bit harder.

[@RaceLine10]

Mr2s have electric power steering xD. you dont need it. It was the car of the future :D

[@alejandrocuriel651]

I have a 93 na automatic and I’m currently swapping a 5th gen 3sgte with a manual trans. I’m going to need the harness made where I can plug and play. Can you help me with that???

[@BobPham]

Alejandro Curiel @ wiregap

[@BobPham]

Let doug know what u have and what u need done. He will help u

[@alejandrocuriel651]

Bob Pham thanks.

[@kaneradcliffe5804]

Is this a caldina engine into mr2?

[@BobPham]

budgetbuild Supra yes

[@jayelpea]

Hey Bob why did you convert to gen 4? I haven’t read all the comments below so forgive me if someone already asked that, so is the gen 5 useless?

[@BobPham]

Jose Lopez paz at the time gen4 was available. I run gen5 now since the ecu can be hack now.

[@erickgarcia6906]

awsome video much appreciated!

[@berthiernorde3140]

WILL THE 3SGTE 4TH GEN WORK WITH THE A241E TRANSMISSION? I HAVE THE MR2 5SFE

[@BobPham]

Is that for an automatic 91-95mr2? Then yea but u need to do some mods on the plate and wiring harness. Basically you can swap trans between 5s with 3s engines.

[@dennisl4961]

How is the clutch kit and flywheel holding up so far?

[@BobPham]

Dennis Lansang still holding up fine. S54 sucks on the freeway tho. High rpm for daily use. I recommend going e153 instead.

[@dennisl4961]

Bob Pham My E153 is at 3100rpm at 70mph.. this is high, i wonder what is yours like

[@BobPham]

Dennis Lansang no that's not. That's normal. At 65mph mine is already close to 4000 rpm 😢 really loud on the freeway. Haha

[@dennisl4961]

Oh damn... it is high.

[@TheLansang]

Hi, where do you source the replacement parts for the Gen4 3SGTE, such as timing belt, water pump, etc? Thanks

[@BobPham]

TheLansang I sell them as well. Email me at [e-mail]

[@TheLansang]

Bob Pham Do you have part numbers?

[@Rollracer28]

Is the engine from a Caldina?

[@BobPham]

Austin Klanjac yes

[@TheLansang]

Cant i use gen2 downpipe since mine is a CT26??? Why gen3 downpipe as you mentioned

[@BobPham]

TheLansang because the head on Gen3 and g2 are different. Gen3/4 are the same head. U have to use Gen3 dp on Gen3/4 3sgte. U could use gen2 dp. But u will have to bent it like crazy to make it fit if the dp have a flex section. If not u can't bent it.

[@TheLansang]

Bob Pham Make sense... thank you for helping.

[@TheLansang]

Bob Pham Make sense... thank you for helping.

[@johnnynguyen7642]

where do i get the wire harness from?

[@BobPham]

Johnny Nguyen wiregap inc

[@dennisupra9796]

Hello... So Gen2 exhaust manifold wont fit the gen4 head?

[@BobPham]

Denni Supra nope. Only Gen3/4 are the same

[@dennisupra9796]

one more question... how is the stock CT15 for mostly freeway driving? do you prefer upgraded CT26/27 or upgraded ct15 by campos or Prime?

[@BobPham]

Denni Supra stock ct15 will do 299 whp with 30% e85. Go see my latest dyno video. If u want to go billet get campos. I run campos bullet Ct wheels. It's legit. Just say bobmr2 refer u. He hook u up.

[@dennisupra9796]

Yeah i just talked to him over the phone for like 30 mins.. gave me a lot of info.

[@cowboys1aq]

Bud where do you live

[@dennisl4961]

2:28 is that bracket from a 5S? The one with white paint?

[@dennisl4961]

Ok... got this one. you re-explained it by the end of the video

[@BobPham]

Oil filter under the Ac compressor

[@cincomorales]

Hi bob i need you to make me a custom wire harness for my st246 toyota caldina engine please i emailed you already

[@cincomorales]

I have a question, im putting the caldina gen 5 on my mr2 1991 n/a ! Can i use the n/a transmission with the n/a clutch fly wheel and pressure plate ? Please help!

[@BobPham]

jessie morales u have to use 3sgte flywheel and PP. U new to use s54 disc. Or u can get a custom disc that has a 3s disc with s54 spline.

[@cincomorales]

Thank you bob ! I got it already! Now i have another question for the caldina 5th. Get ecu wire diagram where do i get it ! Thanks

[@BobPham]

jessie morales I would just have it made for your car. The hard part is hacking the ecu. If u need it made or have ecu hacked. U can email me [e-mail]

[@mrs_radrod]

Are you going to run the motor out of the car to see if it will work before putting it in the car? Lol 13 minute video is perfect for this sort of thing.

[@BobPham]

I already did a compression test (180psi all across). and did an overhaul gasket kit replacement.
