Turbo MR2 motors

[Bone]

Ok so i'm picking the car up tomorrow as i have the day off and will be going down to pick it up as soon as the man gets home and i can get my brother to take me down there to pick her up.

I am looking to make start building a new motor to go into it that is turbo'ed along with a matching trani. to handle the extra power.

Do we have any Yota buffs on here that could recommend parts/setups to me? I have a friend that's trying to hook me up with a second motor for pretty cheap. basically it will have to be completely redone from the bottom up.

so through out your sugestions and lets read what you have to type.

well obviously u need the 3s-gte motor and the e153 tranny from a turbo mr2. or u could if u want got to http://www.rippmods.com they have a supercharger for the 5s-fe (non turbo) u could go that route. or if u had the cash laying around u could go 5s-ge route which is the 5s-fe block with a 3s-gte head. its all up to u.

Turbo MR2 motor = 3S-GTE

Then go to www.mr2oc.com (http://www.mr2oc.com) and read.

I can talk to my boy, see what all he has laying around still. He sold his MR2's but lord knows his garage looked like a toyota dealer. He had a few mr2 engines, turbos, manifolds, ecu's, etc. I'll see if he has anything left.

check www.toyotanation.com (http://www.toyotanation.com) they should have some write ups. Also googling works.... When I looked into a 3sgte swap for the camry alot of stuff I found was for 3sgte into celica.

I like this, http://www.rippmods.com/products/products_list_details.asp?menuid=3&productId=249

but i'm not sure, i'd like to reach 18psi but still reading about what would be the right parts to use.

well the title of your post asks for turbo mr2 motors which is the 3sgte. also dont worry about psi, worry about how much power you want. psi has nothing to do with it.

You could always drop in a camry V6 engine into it and strap on a S/C or turbo it!

he could but its too much work

[Bone]

he could but its too much workgood point. I was considering the camry v6 motor but that's just to much of a tight fit and getting it to cool would be a little bit of a pain as well as being on boost that I just wouldn't want to work on after a while.

I think i'm going to stick with doing up the 5SFE - 2.2 US spec N/A DOHC with one cam gear.

it's a bigger motor and as long as the block can handle an output of 300-400hp i'll be satified. hell 300 hp in this little car will be more than enough. I think that if i can reach 350 that would be about the prime zone. any more than that and i'm afraid i might have to much funa nd get to many tickets.

As it is I have a few cops that still watch me to this day, some how they found out i'm back in town. but then again i have a few friends that now are area cops and all. I need to swing by and see the guys and have them over for beers. I went to high school with these fuckers and now they are the ones writing the tickets.

that's what i'm shooting for at this time anyway.

You should use either 1zz or 2zz, remember that engine weight plays a huge part in the car's balance and you dont want an iron block in there. 2zz is a direct swap and seems to be a favorite choice of on www.spyderchat.com(good (http://www.spyderchat.com%28good) forum btw). I would go with that. I personally use 2zz + 6.5psi turbo on stock internals. No need to get inside the engine, you'll be good for 250-300whp on 93. I would say 250whp is plenty for the spyder and should put you well into 12's in the 1/4 and low to mid 4's 0-60. This is not a drag car, keep it balanced and predictable and dont forget to work on weight reduction, suspension, tires, brakes, lsd, etc.

he doesnt have the m2-s he has the mr2 from 92-95

[Bone]

he doesnt have the m2-s he has the mr2 from 92-95psssst pssssst bro it's a 91. but yeah they made the NA mr2 from 91-95

[2slo4u]

whatever. still the same car.

[91mkII]

I read some where if you can make 300 to the ground and can find some traction you can lift the tires off the ground.

[GDM Z28]

drop a ls1 into the bitch lol

[Bone]

I read some where if you can make 300 to the ground and can find some traction you can lift the tires off the ground.
Traction would pose a problem. To do someting like that I would need some serious tires, some wide slicks. but I don't really car to run that fast with the car. I just want a high powered sexy car, this is a great start on that track.

[02Vortech]

doing the 3sgte swap is by far the easiest but also as i told the person who owned that car previously the 5sfe is capable of handling boost but here is what you need.
(5sfe Turbo is about two tenths faster than a stock 3sgte because of the displacment spools the turbo faster... No replacment for displacment.)

The 5sfe is a good block but the throttle body is only 2" in diameter witch become restrictive above 200 flywheel hp. The intake manifold becomes restrictive above 240 flywheel hp. As far as valve train goes, just try to get a 3sgte head, or if that doesnt work out, go w/ ferrea valves (w/ 3way valve job if you want best valve train), crower valve springs, seats, and some machining will be required. The stock components become a fatal flaw above 6300 rpm.

The strengths of the 5sfe are
Solid block - High powered 500+rwhp MR2s often use these blocks.
- Stroked crank - The 5S-FE is a stroker motor from the factory. Also used in 500+rwhp MR2s.
- Displacement - 2.164 liters which is great for spooling a turbo.
- Long intake runners - Although bad for high revs this gives more velocty for torque down low.
- 9.5:1 compression - Good for NA power and low boost power but limits the maximum boost.
- Fuel rail - The fuel rail on the 5S-FE is a top feed rail which is capable of supporting 850cc injectors or maybe larger

Limitations:
- 6300rpm redline - Valve springs and connecting rod bolts are not strong enough to be reliable past this.
- Short duration cams - ~220? and 8mm lift. The 3S-GTE has 236 advertised duration and 8.5mm lift.
- Small valves - 32.5mm intake and 28mm exhaust. The 3S-GTE has 33.5mm and 29mm exhaust.
- Linked intake and exhaust cams - There is a drive gear that keeps them synced so an adjustable cam gear can only be put on the intake cam and it also effects the exhaust.
- Small exhaust ports - Intake ports are good for oversized valves but exhaust need to be enlarged for flow.
- Fuel pump - Only good to ~235rwhp at stock pressure.
- 5S-FE Computer - Runs rich and is made for the stock NA injectors.
- Injectors - Made for max 150rwhp maybe less. 91-92 injectors are 205cc (yellow) and 93+ are 225cc (Dark green).
- Intake manifold - I don't know the limits of the 5S-FE intake manifold but most people shooting for high power replace it with a custom one. I suspect it would become a bottleneck in the 250-300rwhp range but that is just a guess.
- Throttlebody - I also don't know the limits of the stock throttlebody but it is only 2" in diameter which is wrather small. I suspect the 5S-FE throttlebody will become a major bottleneck at 200-250rwhp depending on the boost level. Again this is just a guess.

EASIEST WAY TO GO FOR CUSTOM KIT.

Factory 3s-gte Turbo CT26 with wastegate actuator
Factory 3s-gte Elbow
Factory 3s-gte 2bar MAP Sensor
Factory 3s-gte Exhaust Manifold
Factory 3s-gte Intercooler w/ fan
Factory 3s-gte Oil Pan
Factory 3s-gte Oil/Water Coolant Lines to and from Turbo w/oil drain hose and clamps
Factory 3s-gte turbo to intercooler Pipe
Custom intercooler to throttlebody pipe Factory 3s-gte Blow Off Valve with the VTV valve
4 MkIII Supra NA 315cc Injectors
4 NGK spark plugs that are 2 levels colder.

CAMS
Webcams make cams that will increase duration and lift. Webcam grinds of 294, 577 and 101 should increase performance and still be streetable. 3S-GTE, 272 cams would probably be the most aggressive streetable cams and need an EMS to idle them.

VALVES
Use valves from a 3S-GTE for 91-92 5S-FE and valves from a 2JZ-GTE for the 93+ 5S-FE for 1mm oversized. The +1mm version of these valves will be +2mm in a 5S-FE.

5SFE COMPUTER
Runs rich and fires the injectors in batches. Also it can't idle a set of aggressive cams. Replace with a standalone or add an advanced piggyback.

6300rpm redline - To safely go above this you need upgraded valve springs (3S-GTE springs for 91/92 or 2JZ-GTE springs for 93+), forged or 3S-GTE rods because they will have bigger bolts (3S-GTE and 5S-FE rods are almost identical except for the rod bolts) and a stand alone computer to raise the rev limiter. 3S-GTE rods can be made to fit by grinding the crank journals down but they are also a few thousandths shorter then the 5S-FE rods so that can slightly lower compression.

Intake Manifold - stock manifold can only move so much air so choosing the correct runner length and plenum volume in a custom manifold can add some extra velocity at different rpms and boost pressures. Most of the custom manifolds for the 5S-FE are side feed to keep air flow as even as possible between the cylinders.

- Throttlebody - some people use a Mustang throttlebody to get a bigger bore and get more air flow. This requires some custom machine work to the stock intake manifold to make it fit or a custom intake manifold.

- Oil Pump - Replace with a 98+ 5S-FE pump and shim the relief valve 1-1.5mm to get a higher pressure. If you do this you may have to put a restrictor on your turbo oil feed line to keep from blowing oil past your seals.

10PSI ON A 5Sfe = 180whp

So obviously it can be done... but cost effectiveness and much less hassle and headache=3sgte. Plus i think driveability comes hand in hand.

I do like the idea of side fed intake for distibution. Now I just have to get my truck back to the dealer to be serviced and then up for sale it goes. then it's time to start work on the new motor

No problem. You got the 4.3L in your truck? If so STS turbos is comming out with a kit for our motors that puts 300whp to the ground on 8lbs of boost. Also cfm-tech is making a new intake manifold for our motor so it is much more boost friendly. Anyways good luck w/ the MR2.

[JDM93MR2]

The car does not need much horsepower to compete with other cars, There are mr2's just around 300whp (318whp, 296tq),"no shoes" moore, running 11 second 1/4 mile times. John Ray ran 12's in his 218whp 2.

The 3s-gte comes from factory with around 7.5-8psi, reliable non+/- boost gauge and a www.twosru.com mbc(50$) and I have ran 14.5psi on 3 different Mr2's with no problems. Throw any of the 3'' exhausts avalible (TKO for the hardcore exhaust fiends) and instantly the car is a different beast.

The 5sfe is a potent motor, but so far it has not proven to be worthwhile to me for the everyday tuner, if you can handle alot of downtime, money, and maybe a little frustration the 5sfe can be a competent motor, but it seems for the same price you could have LSD, and a much faster factory motor. The J-Spec motors have stronger engine internals then the 3s-gte's we got in the states. Prices for a clip are not bad, I got my 93 LSD Trans from toyota for 3200$, but most LSD 2nd gen clips are around 2500-3500$, 96+ are a little more.

Glad to have another mr2 driver :)well aint this some shit, welcome to the board man.

yeah for the past month i have been researching and right now i have settled on just putting in a 3s motor due to the easy of it. but it will definately be getting upgraded parts all around. this way it will jst be easier to itegrate everything. pluss I have to keep a working AC unit in the car. I was orginally planning on building the camry 6cyl motor to swap in the car but then i decided the hell with it. it's just to much damn work when i do a hell of a lot more with the same amount of cash and less time.

I found this sexy little thing that I will most likely be using on her http://www.andysautosport.com/product/detail?_p=GRED00041020&_v=vmd00408

so were are you in FL?
