I just got my 5sfe rebuilt with 8.3:1 compression ratio forged pistons, 3sgte rods, everything except for the cams is brand new. The motor should hold 21psi, and my T3 maxes out at about 19psi. By next spring I'll have my intercooler installed, a 3sgte fuel pump, custom fuel rail with Bosch 550cc injectors, MSD Digital 6, and Haltech stand alone. Has anyone done anything like this before? Any ideas on how much I should be putting down (on one wheel for now.... desperately need a limited slip) I'm really curious to see how much of the 5sfe "torquey-ness" I'll retain. Could I touch 11's with a limited slip and some drag radials?
Yes, turboing a 5SFE has been done before and the guy who did it is in the 10s.
I would think you are going to need abigger fuel pump than the 3SGTE one.
As for limited slip, that is not necessary in the MR2 for drag launches. It helps our cars get power to the ground out of turns. Although the MR2 does tend to put more power down to one wheel, it still applies power to both wheels ... there is not a huge advantage to LSD in the MR2 at the drag strip.
NoSir ... not sure why you would say 11s are not going to happen on a 2.2 liter with a T3 turbo, but there is at least 2 people who have gone 11s with a the 2.0 and hte CT20b.

Most T3's are very small turbos. You can get them with almost any trim you want, but in most cases they are stock turbos off of junked cars. Not saying his is off a junked car though! But I would like to know more about the specs of his T3.
it's the Garett TB0344 from the Burien Toyota 5sfe turbo kit. Looks like medium sized turbo but I don't have much to compare it too. I do know its a lot bigger than the stock DSM baby turbos on the Eclipses. Would a TD06 produce more power?
That's interesting about the Limited slip, cause I remember laying down just 1 line of rubber whenever I launched. I wouldn't get much traction til 2nd gear.

... I have seen owners put down to lines of rubber without LSD in the turbo MR2. Regardless, when you are laying down rubber you are intentionally breaking traction so power would go greatly to one wheel. If you are properly launching the car, then power will be going to both wheels.
I own a 91 celica running a pretty tired 5sfe engine with standard diff and it lays down rubber with ease. It doesn't seem to be favouring one wheel either.
jekylandhyde, i dont understand when you say "if you are properly launching the car the you should put down power to both wheels". Ive too also laid down rubber with the torquey bottem end'd 5sfe in 1st easilly. But, ive always spun the passanger side tire. And the td06 is a VERY underrated turbo. The t3 you have sounds like a nice turbo, but i would have gone with probably a garret t3/to4e 60 trim with a .63ar. Because the 5sfe being the extra .2 liters more than the 3sgte can really spool a turbo quite a bit faster than the 3s and can hold that power till redline because of how low the redline is. But anyways, it seems like you have a really really nice setup, are you going with the 3sgte head??

Explanation: laying rubber is not proper launching your car.
And ideal launch would be just a hint of a chirp and you are off.
If you are "laying rubber" or doing a burnout, you are intentionally breaking traction and then it is quite possible that you will expereince one wheel on an open diff spinning.
If you properly launch an MR2, using the max power to the ground without breaking traction, you will have power going to both wheels.
The factory LSD is not a huge help to drag racing an MR2.
WhiterMR2, I have a 3SGTE. I have not and would not turbo the 5SFE. Regardless of the 10% more displacement, it is a significantly weaker engine with a poorly designed head.
ahhhh ok i get what your saying now , good explaination. And the 5s block is recemmended for a stroked 3sgte platform right?? do you know what i mean?

Yes, but using the "block" is not anywhere near using the "engine."
That is merely one piece ... the 53Fe internals and head are what have no value in the pursuit of horsepower.
The FE head is not for performance. Its design for fuel efficiency and torque. You can get more from it with P&P, cams, valves but you won't get as far as the GE head. If you want high HP, you'll need the GE head.
You don't really need those. GE head acturally is higher then FE head, wider valve angle so the piston won't hit anything. You'll get a bit lower CR. All you need is a RPM switch to activate TVIS at around 3500-4000 RPM. Keep TVIS for better lowend. Removing it doesn't help much in highend.
