View Full Version : engine options for mid engine

just would like to know what would be a good engine and tranny for a mid engine car not toyota specific

What kind of vehicle is it going into? Otherwise I'd just stick whatever (light and tight) big engine and transmission I could and call it a day (I wish it were as easy as that). But because most mid engine vehicles engine bays are pretty tight it can be difficult to fulfill.

Since there aren't too many (mass produced) mid engine road production cars I'll just list what has been done/in the process.
AW11 (first gen MR2), SW20 (2nd gen), MRS
- Northstar V8
- Camry/Solara V6 (even the guys in the UK are fitting the newer Evora/RAV4/Camry V6)
- Audi V8
- Honda/Acura k20,F20, F22
- Toyota 3sgte/5sfe
- Toyota 4age/4agze
- Toyota 2zz

In terms of what is good that can be subjective and again dependent on the vehicle in terms of cost, application, size, dimensions, fitment, complexity, etc. Is it going to be a track car, hillclimb, rally, outright speed, drag, etc. With enough time, research and money I'm sure you could stick just about anything in (think Hennessey Elise Venom).

If I could my dream swap would be a Toyota Atlantic 4age or a race spec'd 503e from Toyota. Then again I wonder if you could shoehorn that awesome V10 from the LFA into an AW11? There are so many options and variables that it's difficult trying to decide what you could do.

any FWD engine can be used in a mid engine configuration. also, if you are going to be mounting is transverse or longitudionally...

I mean hell, you could use a BMW V10 (like McLaren F1), or any of the Lambo V12s, V6s, Inline 4s....

there are a million variables...

I think I saw a 3sgte in a mid engine car before.

3800 S/C'd?

I could seriously go all day for this. I need some restrictions: chassis, application, etc

The new Ferrari/Maserati F142 looks like a good place to start.

Any one off project should have a north south engine setup. If I were doing a ground up build I'd use a v8 maybe an ls maybe a uz and a Porsche transmission with the pinion gear flipped to work as mr. Or possibly a beefed up 914 transmission. Of course there are quaife and hewland transmissions if you are made of money.

If you don't want to use a v8 I'd say use a Subaru turbo engine.

just thinking of a lambo kit car on an mr2

Turbo a 3VZFE and run a couple Borla XR-1 mufflers to get you affordably close to what you want to do (cheap lambo). It's well documented and not too bad price wise.


You can always make your MR2 a widebody. They have the EVO-F in your neck of the woods. Insta-envy from all us mid-rear fans.

IF you wanted to go big, you could get the 3.4L 5VZFE and Twin Turbo it, converting the trunk for intercooler space off a Volvo. I have read about 2 build-ups this way. Crazy power from such a small car.

I wouldn't put a vz in anything. The mz would be An awesome choice. A 2gr would be super mega awesome.

Weight mainly. And there is the head gasket issue. Most were fixed though. Not saying it's a bad engine it's still pretty good for what it is but is it really that much cheaper than an mz engine? Cause the only reason I can see to use a vz over an mz is budget.

I'd pick a 1MZ. http://www.autoblog.com/2011/09/23/728-hp-toyota-camry-is-the-ultimate-sleeper/

I've done research on the three engines for a couple years now. My preferences in order.



We like our 3SGTE and 5SFE because of the midrange torque band. Cast iron block gives you that along with a sturdy platform for going forced induction. If you want to do a N/A build and don't mind dealing with OBD-II, go for the light weight, more expensive solution. Being OBD-1, having a stronger bottom end, larger displacement and higher rev limit (better gearing); the 5VZFE can be built into a 3.4L monster.

Assuming you are getting a used motor, rebuilding is probably already in the plans. Copper head gasket, forged internals and the cast iron motors are good to go.

Besides, Toyota Raced them running 1000 HP on methanol. Please do that build :D

I really dint think a vz has that much stronger a bottom end than a mz. But maybe it does. I wouldn't have any problems boosting a mz to 12# or so on a stock block. I do know that the material your block is made out of has nothing to do with midrange power.

Copper head gaskets are an old domestic car trick for high comp or fi motors. And they worked. But even NASCAR is running mls gaskets now.
