The SR20DE(T) is all aluminum.

The motor is also listed as an economy engine (not fuel efficiency) in nissan's lineup in the year 2000. This was written in an SAE paper.

If you want economy, slap in a diesel. The new TDIs are making over 100whp (rated at 90 crank factory) and close to 200 lbs/ft stock. Far greater when modded. Or the older IDI diesels (1.6L-1.9L) were excellent as well from VW... Hmm 65mpg+ FB ;) that could run seriously good times due to low mass :cool:

Really? Hmm, why was I thinking they were iron-block?

Usually "beef" engines are iron block for strength. That's what gets me about the Duratec: beefy (they use the blocks in WRC restrictor motors after all)) yet aluminum.

id go with the 4age cheap and easy to work on and very reliable they make around 100 stock. the motor is revy and woulod fit the fbs charcter.

I've been doing allot of research to find the best "overall" engine for a four cylinder swap. After the dust settled I came up with a 4g63 of turbo eclipse fame. They can bolt to a dodge rwd truck trans. and they have an adapter to mate it to some toyota trans. so that takes care of the "it's a transverse engine" problem. I can't see this being anymore difficult than the chevy swap with the exception of the mitsu. being fuel injected, but then again I guess because of my age I know more about fuel injection than I do about carbs so it may actually be easier.

Now you are thinking. 4G63 has routinely made 475 awhp on a totally stock motor. It is a seriously strong iron block, and is not all that heavy. Aftermarket galore as well.

Tell us more about this adapter for a toyota trans. Who makes it, what trans can you use etc.

Have you thought of I6s? like out of an older Supra? Thatd be cool.

LOL, the sr20 is literally "bullet proof"

Nope, The S2000 engine is an F-series. F-20 (00-03) and F22 (04).

And my F22 put down 211 rwhp bone stock...with less than 5k miles on it. Find me a Duratec that does that.

But in all fairness the F series honda motors are really expensive, even used, so I don't think they make very good swap material.

F22 came in the S2000? really? I was working on a newer accord today that had an F22 in it.

My bad on the K/F. (So wait... if it's 2.2l now, why isn't it called an S2200?)

Want a Duratec that does that? Okay... :) I can't link because the site only allows members to view their forum, but here's the text:

Many other people are getting 330+hp out of these engines with cam changes... and no porting.

2.3T ford

Here is a copy from my post from a thread just like this a week ago :)
https://www.rx7club.com/showthread.p...5&pagenumber=2

I will have to vote for the 2.3turbo ford. They are built like a brick shit house. Cheap as heck and parts are available at any junkyard to get them running.
Mine has a few things done (all cheap things) and it is putting out around 340 or so at the wheels (working on more) and it will do this for next to ever without wearing out. And can be made to make big numbers pretty cheaply.
I'm not really sure what mine gets as far as mileage goes, most the time I am in it, I am in it lol But when cruising down the hway the engine isn't even trying.

The fit into an rx pretty well, and the ford t5 5-speed hits the shifter hole like is was made for the car.

Over all I love my litte rx, I have little money in it and it is great to see the look on vette/camaro/mustang owners faces when they are trying to figure out what the hell just happened

Wow. I must say, that even for the blasphmous act of putting a piston in a Rex, that looks pretty slick. And stock. Awsome. What did those engines come in?

All 4 cylinder engines. Honda 6 cylinder engines run the 'proper' way :)

++ gotta love the only engine i know of that will take 20 psi in junkyard trim

Well, I've been thinking of this too. What is the best engine for fuel economy and performance. So far I have only found the 2.3L Ford engine, which I can't get with a turbo around here (rarer than the RX, which was hard enough to find). I don't really like ford too well though. But I've grown up in a family who is totally against fords, except the mustang.

I need some pretty good reliablility, fuel economy, and I'm having a hell of a time getting my exhaust quiet enough. I fear I might spend more money trying to quiet my exhaust down than the engine swap would cost.

I would consider a VW TDI, or even 1.6L IDI engine, just for the pure fact that they can make some pretty good power and awsome torque. It doesn't take much in a diesel to make 100 hp over stock (for the V8's, all it takes is injectors, or some ECU programing). You can get over 50 mpg while making over 150 hp in a diesel. I just don't know if the aftermarket is there for the older VW diesels like there is for the newer Ford, Dodge, and GM ones. I'm sure I could get one to mount to the stock 7 tranny too.

On top of all that, they are built almost industructable. I've seen some with 450,000 KM without a rebuild.

If someone made a kit for a 2.3T swap for a good
price I would do it

the mounts are almost the same as a 302, which are almost the same place as a 12A or 13B i cant remeber

Don't forget the 2.2/2.5 Dodge Turbo.

almost as good
but they do tend to break more than a 2.3, but not too much

and the whole FWD thing

86-88 Ford T-bird Turbo Coupe, Mercury Cougar XR-7, Merkur XR4ti, SVO Mustang.

There's another bad-a$$ 2.3 Turbo RX-7 at http://www.boostbros.com/

Although some people say not to use the 4age, i say go for it, my bro had one in his corolla and it is a relatively high revvin(7500 redline) quick little engine. It would work well in a first gen. If you want my advice then i say go for a 4agze, its just a supercharged version put in some of the cars in japan. Well thats my small amount of input, hope it helps.

Um, no. They're bulletproof.

The only possible reason they might seem like they're less beefy is while Ford only put the 2.3T in specialty vehicles, Mopar put the 2.2/2.5 in EVERY SINGLE FWD CAR LINE from the Omni to the New Yorker, including the minivans. It was their "upgrade" engine before they had V6s in available quantity.

im not saying they are bad, but in my experience they are a little weaker than the 2.3

tho both are better than any forein 4-banger with boost IMHO

:rofl:


3S-GET.

By the way, the Mopar engine is a loose copy of a VW (ex-Audi ex- Mercedes) 4-cylinder engine. The Ford engine is a "big block" version of the "Pinto" 4-cylinder, which is a European (UK or Germany, forget which) engine.
