Anyone heard of putting a 3rz-fe into a mr2. Will it bolt put to the transmission. The reason I ask is because i found a Mr2 with no motor that Im getting ready to buy. I can get a 3rz for pretty cheap and elprototypes makes low comp. pistons and turbo kits for the 3rz.
Originally posted by MRQturbo i've never heard of that swap being done...why not just swap a 3SGTE in there....save urself alot of money and headaches......
btw..what motor is that from that ur talking bout??.....
3RZ-FE is a 150 hp 170tq , 2.7 liter 4 banger n/a. Its a twin cam motor from a tacoma. http://www.toyotacelicas.com/feature...hp_celica.html
Elprototypes and LCengineering makes forged pistons and other engine internals for this motor. There are also turbo kits on the net for it too. A turbo'ed 2.7 would be more responsive than a turbo'ed 2.0 and have more power potential. A lot of custom work would have to be done but this thang dont have to be done by tomorrow. What really bothers me is if the mr2 tranny will fit, and if it dont is there and adapter .I got another car that I drive everyday so. This car is going to be built right. If i stick with the 3sgte, by the time I buy a motor rebuild it and get and aftermarket turbo ect. ect. the costs wont differ too much.
150hp.. wow.. (sarcasm..) Id go for a 3sgte, has more power stock and if you go with a NA with attempts to build it up youd have to change out the internals. For example you wouldnt want to run 25psi with 10:1 or whatever compression pistons that NA engine uses.
The GE or GTE engines have wider angled valves and offer a wider range of cams. Plus the g engines have a much higher end where the f series offer lower end power. F's are great for trucks where you want the power at the low end (for towing or climbing) but for cars you want that bigger range of rpm. There are more parts for the 3sgte than just about any other engine, considering the time period used in the MR2's and other Toyotas. They are more popular than the Supra engines. Sure there are bolt on kits for F engines but they are very limited in the amount of power you can get, primarily because of that compression ratio.
Im considering getting rid of the 4AGZE and switching to a 3SGTE. Id have about the same amount of power I have now with a stock engine. The 4A are great little engines but are limited in performance except if you want to dump a lot of money into it.
Theres been a few people that have installed a v6 (Toyota, GM) along with a northstar caddy engine, its definitely nothing new. I wanted to install a Lexus alum block v6 in mine years ago but its just a matter of being able to do it. Gerald, the builder of one of the twincharged MKI's as seen in SCC (if I remember the mag right), suggested that I even consider a v8 from the Tundra. I havent looked at the latest possibilities, such as the new v8's offered in the 4Runner, so Im not sure what engine they are or if they are alum or not. My main concern with doing a engine swap is keeping the weight down in the rear as much as possible considering even with a stock car the ratio is something like 42/58. You throw in a v8 in the rear that has a cast iron block and you throw more weight on the back. Im more into the cornering rather than down the quarter which the MR2 was never really designed for.
Im not saying a F type engine is a bad thing. If you have intentions of changing the compression ratio then its not that big of a deal. But still I think the valve size might create a limitation if its overlooked. You cannot just take a stock NA engine (high compression) and feed a large dose of air into it by using a turbo or superc and expect it to survive. And if you twincharge that engine be ready to catch the head as its on its way back to earth.
Im considering the trd supercharger for the Tacoma, and like all of those bolt on sc or turbo kits they have a boost limitation. Theres a reason, because of the compression. No one that is looking for mega boost starts off with a F or high compression engine except if they want to reverse engineer the thing.
If you really want to add some serious boost to a na spec'd engine just be ready for it to blow up and have the highest octane fuel you can get your hands on.
With all that said, figure out what you want to do with the car. Such as 1/4 mile, autocross, track or whatever and pick the rpm range that you need the powerband at. Then build the engine and tranny accordingly.
I dont know of any around Albuquerque. Guess I'll have to start going around to some custom shops and seeing who is doing great work on installs. Ive heard about people sending their cars off the Carl Crawford, who has done quite a few v6 and 3sgte installs. Might cost a bit to send the car off but might be worth it. Would be cool to find someone local. I dont know if the local Toyota dealer can do something like this but I do know of one in Vermont that does custom work, body, engine, etc.. so hopefully we can find something local. Its a pretty good sized city, must be someone here competent enough.
I talked to Stephen Gunter (Gunter Automotive) who is based out of Jamaica and has a business partner in AZ I think. If they are still active, Stephen said I could send my engine to his partner, have all the parts ordered and such and then he would fly over to rebuild it. I think if I go the route of the 3sgte I would probably just leave it stock, for now, and get everything working first.
you know i went to the toyota dealership here and talked to Bill my mechanic the other day and i mentioned to him that i was going to get my new motor soon and have it done some where in abq, and he looked at me funny and said why? we can do that here. he said hed get back to me on how much, maybe arm an a leg probably.
the whole idea of sending my MR2 out to get worked on is pretty good and thats prob what id do. although id like to go to abq and find some good shops, im military so its kind of hard to find time off. but thanks for the info roger. good deal
Which Toyota dealer are you talking about? I wouldnt mind going to them as long as they put forth quality work for a reasonable price. Wonder how well their paint shop is..
Im ex-AF, was stationed here before and know the area fairly well which is the reason I moved back, plus the weather is nicer here. I know what you mean about time off.
I have to say that Malone is pretty good as far as buying a vehicle, I never had a dealer call me to see if I had any problems and how the car was going. If their service depart cares as well that would be cool.
its a dealership here in clovis, im still waitin on how much its gonna cost. the dealership was pretty cool to me when i had some probs with my car but im still deciding on lettin them do my swap.

wowo hold on ... I have a buddy that has a Tacoma with a 3rz-fe and his boosting 20psi on the El Protoypes turbo kit with a a custom hybrid turbo on there... And thats on stock internals with alot of tunning and black boxes... Trying to have him switch over to an AEM unit with a custom pig tail...
Keep us updated on how long that engine lasts. For a everyday driven vehicle I wouldnt expect that engine to last too long.
Ive been a MR2 member for some time now and we've frequently discussed which one was better, the factory ECU with add-ons or a aftermarket unit. Personally I think the aftermarket unit like the TEC units are the way to go if you have intentions of going beyond just simple bolt-on mods. I know a lot of people that have sent their computer to have it reprogrammed for a certain mod, I think that is just too time consuming if you kept doing mods in small steps. Besides like the Electromotive units you can do away with the maf and go with sd or manifold pressure.
At this point Im not too interested in moding my Tacoma, I bought it primarily so I can do some heavy work to my MR2, and possibly either change out the engine or build a twincharger kit for it. Heck, I dont even know the compression of the v6 that sits in it. But give it some time and Im sure I'll be wanting to do something to it.
