Turboing a n/A

I searched the forum for "turboing n/a" but nothing came up..but is it posible to turbo a NA MR2 or would it be cheaper to jsut do a 3sgte swap?

it's possible, but not worth it when compared to a 3sgte swap

The NA engieen is not a good engine to make real power on. Lots of folks have turboed the NA and ended up with blown up engines.

If you want power, go for the the 3SGTE engine.

where can I buy 3sgte automatic tranny ?and how much ? it should be usdm or jdm? :smile: :) :iceslolan :eek7: :p :rolleyes: :biggrin:

There were no automatic turbo mr2s.

i'm not looking for alot of power just 280-350

280 - 350 is a healthy amount of power ... and you chances of blowing up the 5SFE trying to get there is really good.

what is 5sfe? :rofl: :lol2:

The 5sfe is the camry motor found in US NA mr2s from 91-95.

2.2L 130 hp. 135hp from 93+

ok thx for the info guys

what abouty building up a NA MR2 too about 300-320hp to the wheels, and also getting the redline up maybe 2-3k. is this posible?

if we try 6cylinder lexus 6 speed? I heared its lighter than 3sgte motor.

whaa....i thought someone had finally said something about a NA build up..lol think u in wrong thread bro

Tougeman, the NA engine (the 5SFE) is not worth investing in. Your money would be much bettter spent on the turbo engine (the 3SGTE).

gelcol just makes random comments and questions ... easiest just to ignore him.

ok thx jekyk...just trying to figure out which way i wanted to go

I would suggest first figuring out what you want the car to do.
What is your goal?

Do you want a drag monster? A road course beast or an autocross king? Or just a nice street car with extra pep.

Each answer may offer an indication as to where you should go next with mods. People often talk about getting more power and neglect to talk about where they want that power and how they want it to come on.

I looking to make a road course car, but i still want it to be able to drive it on the street.

the only way you might want to keep the na car with a na engine, is if you do a lot of street driving and care about mileage, or if you want to build a EStock autocross car.

the 3sgte swap is probably the most common for what you want to do, and will probably work the best.

i have never heard of more than 200rwhp coming out of a fully built 5sfe.

Neither have I, and to reach that requires way too much money.

Depends on how fat your wallet is!

Highest normally aspirated was the Toms T020 @ approx 245bhp. Will set you back about £10,000. This car was just unusable for the road and was infact a track car.

Most mods will create minor improvements. really in this order...

Exhaust/decat 8-10bhp

Induction kit / cold air feed 5bhp

Dastek unichip 10-15 bhp

High lift cams (risk of spitting the shims out on rev1/2) / adjustable pulleys 10-15BHP

2.2 ltr stroker conversion

Every time you mod the NA the power band will move upwards, leading to gutless performance around town.

Best £ vs BHP ratio is nitrous. £600 for 50bhp at full throttle and a nice dollop of torque to boot

Easiest way to low 14's qtr mile.

Cheapest mod is to lose weight! You can shed alot of Kg's if you try hard enough.

you guys seriously underestimate the 5sfe..check this fully built 5sfte (scroll down) http://www.jimsnodgrass.com/tec.htm
515whp, 355wtq..ran 10.9

ummmx2, we are not underestimating anything.
I assure you I am very familiar with Mike Colon's (Tec MR2) car. And they car is far fro ma 5SFE.

You might want to really look into his car to see what he has going on in there.

He's basically just using the 53fe BLOCK .... not much else. 3SGTE head and custom internals.
You really want to call that a turbo 5SFE?

You may also note he is no longer using that set up ... he has a GenIII 3SGTE now.

check out itchys 5sfte celica. stock internals running 13 psi..not really built at all..dynoed near 200 whp i believe..its on 6gc.net

The 3sgte will put down 200 whp without batting an eye.

well all im saying is..the 5sfe is not totaly shit. u said it cant really put down more than 200whp when in fact it can..and for the same price as it would cost for a swap..u can get more ponies out of the 5sfe than the swap. of course if ur lookin into high hp goals like 300-350+ the 3sgte is the way to go, but if ur just looking for a quick little street car..and nice boost..5sfte is not a bad idea

Excuse me, please do not put words in my mouth.

I never said:
"u said it cant really put down more than 200whp when in fact it can"

The 5SFE is not an engine I would ever choose to modify. It has a horrible head and it's internals suck.
Do you have any idea how many MR2 owners have blown up 5SFEs with less than 5 psi of boost?

It's not worth investing in.
Do as you wish.

not true jek you can turbo a 5sfe and be reliable me and my friend had turbod is 5sfe camry with 8 LBS of boost for daily drivin and run fine. The 5sfe are great to use you just need to look at the right place. Low comproison piston with turbo and a 3sgte head will run perfect with heavy boost just make sure you rebuild the motor. The develop 500WHP if tuned right and if you have 5 grand to speed to rebuild it includding turbo. i just threw a the turbo from a 91 mr2 in my 5sfe running 8 lbs and runs fine.

Sw2108, if you buy different pistons and use a different head .... how is that a 5SFE engine?

That is a Hybrid engine that happens to use a 5SFE block.

my bad ac427 said that..and if done right 8 psi of boost on a daily driver can be reliable..key words IF DONE RIGHT. and im not saying its an engine i would choose to modify either..but if u do have it, and want modest performance gains..then why not..?

because the cost and trouble of modifying the 5sfe is greater than the performance gains.

if you want to have a "quick" mr2, don't plan on using the economy engine unless you have a really thick wallet.

actually ac427..not really..for the same price its gonna cost for a swap..you can actually get more hp out of a 5sfe..and not to mention a swap is a headache in itself..

ummmx2, above you are talking about swapping heads, building up the internals and adding a turbo kit to the 5SFE to get 200 rwhp reliably.

That's a whole lot of work when you just can swap in a much stronger, much more reliable engine that can do 200 rwhp just by dropping it in and have the potential for 500+ rwhp without ever going into the engine.

To each their own.
If you wish to try and get performance out of a weak economy engine ... be my guest.

whoa whoa whoa..swapping heads..no..your basic turbo setup your looking at 1200 + ic would be about 1700..then bov of course (who doesnt like the sound?)..1900..then you wanna go with internals? fine add 1000..so your at 2900 for a nice turbo kit thats gonna put you at about 200whp MODERATELY..and your STILL under the cost of the swap..itchy at 6gc is running 187WHP//190WTQ http://www.6gc.net/forums/index.php?showtopic=18104..WITHOUT INTERNALS OR HEAD SWAP! his celi is not in ne way or shape fully built (no offense to itchy, he's done a great job), but you can just see the potential of 5sfte if you want moderate gains.

edit: link is: http://www.6gc.net/forums/index.php?showtopic=18104

its also good to note that his grand total was..1400-1600

... tell it to the many, many broken 5SFE's out there that have been tried to be turboed.

all im doin is showing a different perspective..a different way to go..and all u do is knock..this thread is after TURBOING AN NA..and if done right..it can be reliable..a lot of ppl with broken 5sfe have spent a lot of time with the fuel while ignoring ignition as well as timing. but wutever..just go ahead and swap if your up to it

yes, the thread is about turboing a n/a, and the answer is the same as it was in the beginning: it's possible but not necessarily worth the price. what you are talking about doing IS NOT turboing a 5sfe, it IS however, building an engine up based on the 5sfe block. that is not the same as what the post is about; the possiblity of putting a turbo on a n/a mr2. it is still an engine swap to do what you are talkling about.

Well said.

Of course, you accurately answered the original question in your first post :)

wut in the world are u guys talking about..i never said anything about changing heads or ne of that..so y do u keep thinking im talkin bout building the engine based on the 5sfe block..im talkin head and bottom end..the whole enchilada..not even internals (if you dont want)..so i fail to see how you think its not a 5sfe ne more..i even pointed out itchys 5sfe..but ehh..wut can u do..do some research...

wut in the world are u guys talking about..i never said anything about changing heads or ne of that..
Really? What is this:

The 5sfe are great to use you just need to look at the right place. Low comproison piston with turbo and a 3sgte head will run perfect with heavy boost just make sure you rebuild the motor.

..wut can u do..
What can I do?
I can spell "What can you do."

uhh...if you would even bother to look at the names you can see that i am not sw21.....

no, and that's 187rwhp... which proves what i said earlier about 5sfe's

dude..187 is not far off..especially if its not even built yet AND untuned..cmon now..he could easily get 200whp with some tuning..and for a 1/4 of the price..id say thats pretty damn good

how do you figure it is a quarter of the price?

you said

your basic turbo setup your looking at 1200 + ic would be about 1700..then bov of course (who doesnt like the sound?)..1900..then you wanna go with internals? fine add 1000..so your at 2900 for a nice turbo kit...

its also good to note that his grand total was..1400-1600

now... the ~3000 for doing that swap is what it would cost for me to upgrade to about 350rwhp.

and i spent about 1600 on my swap.

ummmx2, for every:
1 person you can show me that has a "reliable" turboed stock 5SFE

I can show you:
3 (at least) that have blown up the 5SFE trying
AND
10 (at least) that have done 3SGTE swap

The only "reason" to even consider the 5SFE is because of the extra .2l displacement which is more than offset by the crappy head and weak internals.

My mistake on the names. Your arguments were similar and you were both going back-n-forth with similar information ... I didn't even realize the person changed that I was debating. Completely my mistake

A tid bit of my personal experience:

I have owned TWO 5SFE MR2s and FOUR 3SGTE MR2s.
I have had to rebuild TWO 5SFE's and ONE 3SGTE.
The 5SFE's were stock (except one had intake/exhaust only).
The 3SGTE's were all heavily modified.

If you do the math, that is 100% of the 5SFE's had to be rebuilt and only 25% of my 3SGTES ... and I had MORE of the 3S' and pushed more power AND more miles on them.

And your personal experience is?

1600 for a swap my ass...maybe for the clip yea..but wutever guys..i was just offering the suggestion for someone who maybe wants a few more ponies out of his current engine..if u re-read my other posts..i do agree that 3sgte is the way to go if your looking for higher gains in the 350+..and if it REALLY only cost $1600 for a swap..dont you think a lot more people would be doing it...? not to mention u guys act like an engine swap is a walk in the park. im def. not knocking the 3sgte..because that is definitely a powerful engine..all im saying is the 5sfte may be cheaper way to gain the power of a swap..200whp is a very obtainable goal..but im done arguing this thread..

if it REALLY only cost $1600 for a swap..dont you think a lot more people would be doing it...? not to mention u guys act like an engine swap is a walk in the park.

because not everyone knows how to weld and rewire a car. not to mention that to do any swap correctly takes time. never said it was a walk in the park, my mr2 has about a year and 700+hour of work into it right now. but between school and the rest of my life, i don't have nearly enough time to work on the car and do what i want to it.

and if it REALLY only cost $1600 for a swap..dont you think a lot more people would be doing it...?
uhm ... do you have any IDEA how many people are going the GEN III swap and those clips are over $2K????
Check out the MR2 Warehouse. I believe they have done over 2 dozen swaps this year, just in PA/NJ/NY. There are lots of people doing swaps. Why do you think I said I could show you at least 10 succesful swaps for every one turboed stock 5sfe you could find?

not to mention u guys act like an engine swap is a walk in the park.
Not a walk in the park at all ... and I do not really recommend it.
It is so much easier to just buy a turbo mr2 to begin with.

all im saying is the 5sfte may be cheaper way to gain the power of a swap.
.... if it doesn't blow up ... then it becomes significantly more expensive.

You can put a 3s-gte head on but its better just to put the whole motor in
