umm thinking about my previous post...i had an idea with a friend a few weeks ago. we were thinking of placing a Honda Vtec in my MR2 1990....will it be possible to fit any kind of Honda Vtec engine in my MR2 1990???
possible? sure i believe you can fit a H22 in there np. but a stock 3s has just as much horsepower. not to mention you can get a LOT more out of it cheaply. the H22, or any honda for that matter requires money, or 1506823923rpm to get power.

Honda?!!! Blasphemy!!!
The 3sgte is an awsome engine. And like Scott said, you can easily build way more HP with less money and hassle than doing a swap with a totally alien Honda motor.
honestly if you put a honda in a mr2 you should be banned from this site!!!
No not really
Its definatley doable but you really dont want to. It will cost more money and more fabrication in the long run. Plus the Honda Fanboys will hate on you because its a Toyota Car..... and the Toyota Fanboys (yotapower) will hate on you because its a honda motor.
If you are like me and dont care what people think, Do it! Its something unique and new, The only MR2 I have seen with a honda motor was an MRS. But really there is much better alternatives out there.
a 3SGTE is a 2.0L Turbo I4 that was installed in the SW20 chassis (MK2 MR2). You probably have the N/A Version, which is a different motor called the 5SFE.
The 5SFE is an 2.2L economy Normall Aspirated motor that has T-VIS (Very similar to VTEC). Throwing a honda motor in the place of your 5SFE will gain you almost nothing, maybe loose something.
The 3SGTE is a Performance Orientated engine that was built for the purpose of moving the car fast. It is a true sports car Motor and a legend in the toyota community. The 3SGTE is a very versitile motor and can be easily upgraded for cheap. There is a wide veriety of parts availible for the motor and its not to hard to work on either.
Dropping a 3SGTE into your car will be easier then a honda motor.
Toyota Variable Induction System, or T-VIS, is a variable intake system designed by Toyota.
It improves the low-end torque of high-performance, small displacement four-stroke engines by changing the geometry of the intake manifold according to the engine rotation speed. The system uses two separate intake runners per cylinder, one being equipped with a butterfly valve that can either open or close the runner. All valves are attached to a common shaft which is rotated by a vacuumactuator outside the manifold.
The engine control unit allows vacuum into the actuator by powering a solenoid valve when the engine rotation speed is below 4200 rpm.Above this engine speed vacuum is cut off and a spring inside the actuator causes the butterfly valve to fully open. The theory behind the system is that in the lower speed band the velocity of the intake air can be improved because the intake runner cross section per cylinder is smaller. However, when the engine gains speed, the required air flow volume is more significant so the second runner is opened to improve the flow.
Toyota used the T-VIS system from the mid-80s to early 90s on its high-performance twincam engines, such as the 4A-GE, 3S-GE, and 7M-GE.
Some aftermarket ECU's can control the T-VIS and let you adjust the turn-on and turn-off RPM'

Correction, the 2.2 Liter 5S-FE does not have T-VIS, only the 86-89 3S-GE and 88-95 3S-GTE (2nd gen 3S-GTE) has the T-VIS. If your engine is the 2.0 then there is a good chance that you have the 3S-GE engine which has about 160 and about 140lbs of tourq wich way better then most honda vtec engines. IF you happen to have the 3S-FE engine, then might as well swap it for a 3S-GTE or 3S-GE beams.
just so i can mention my side, i dont hate that people are creative, but i really dont like mixing cars. i saw a ja70 supra with a camaro lt1 in it. i was creative, but no. i seen some people put a caddy northstar in the aw11. creative but once again no. but espeically since this a site called "toyotanation" it would be an oximoron. but thats me. i'm not a big fan when they put a rotary engine in the ke27 corollas either. especiall since the orginal engine can me set up for 400 hp. just hate to waste a good car over some creativeness
Generally the only reason someone wants to swap a honda motor into anything is because the car was unreliable to begin with or just pansy weak. The MR2 is neither, seeing as how toyota is a little more reliable than honda and the 5S-FE and 3S-GTE engines are both awesome and easily improved upon.
Now, finding performance parts for the 4A-GTE in the first gen, thats a bit harder, but seeing as how you have a 2nd gen you should either leave the engine and upgrade or try to find the turbo motor
