engine swaps

What swaps have you all done to your 2nd gens and what did you have to do to get the engine to fit?

Re: engine swaps

No offense bro, but you obviously are determined to pimp out your car but seem to be unwilling to do the basics of how to do it. First it was more hp, then lowering now this.

Do some homework, how 'bout it? The answers are not hard to find.

Re: engine swaps

I think we need to back up a moment. Nate: what's your experience, and what is it you want out of the car? We all could start talking about Weber carbs and intake manifolds, B-series this and H-series that, and actually tell you very little.

The fact is that you've picked a car that's a bit difficult to modify. As explained before, there's never been much in the aftermarket for 2d gen Preludes, and fuel and ignition system technology switch (carburetors and mechanically/vacuum-controlled ignition timing to electronic fuel injection and ignition) caught the 2d gen right in the middle. To swap your engine for a more recent engine is a custom engineering job -- it's not just a matter of plugging in new engine mounts, but also modifying the fuel system plumbing and laying in all the wiring harnesses for an engine control unit your car doesn't have.

The flip side is old-school modification using a different intake manifold and carbs...but that's a black art, and if you've never worked with carburetors before (let alone two of them), be prepared for a steep learning curve.

So, if you either have lots of experience in something I just talked about, or are looking for a long-term learning project, that's one thing. If you're looking for relatively easy modifications, sell the '84 to someone who'll appreciate it for what it is, and get a Civic, Integra, or a later Prelude, all of which have more aftermarket support. Or be satisfied with the fact that it'll outhandle nearly anything else you'll encounter, maybe look at a few modest modifications (uprated swaybars, maybe an intake), and drive the wheels off it.

Re: engine swaps

I have already started on getting the car back in shape. New brakes( roter caliper pads)
Of cours I did a basic tune up. And also new tiers. My next plan is to get the rust out of the rear right fender. The re painting it.

I was only looking to lower maby an inch just enough to close up the wheel gap a bit
And the hp and Weber questions I asked because no one I know knows anything about that kinda stuff.
Thanks for the input though

understand that people here want to help, but need to know what your capabilities are before suggesting a path for you to take.

if you can work with carbs, great!

if you have some fabrication skills and a decent budget for a motor swap, great!

we just need a little info from you.

Re: engine swaps

That's the other question: go where? It's as possible (sometimes more possible!) to ruin a car by throwing parts at it as is to make it faster.

My advice:

1. If you haven't already, download a copy of the factory shop manual -- any year from '84 - '87 will do. That'll help you learn the car as it is.

2. Leave the engine alone. One of the constants about Hondas is it's not easy to pull more power from them -- they're pretty highly tuned from the factory. I looked hard when I had mine, and the most I ever heard of anyone getting out of the ET2 engine in your car is 130 hp, by a tuning outfit in New England familiar with carbureted Hondas. (They've been out of business for over 20 years, so no help there any longer.) When Honda converted that engine to fuel injection and enlarged it to 2 liters for the Prelude Si, they extracted a whopping 10 hp. So learn to love the 100 hp you have, and work on getting it to the ground effectively.

3. Start with a decent set of tires. That may mean new wheels as well, as 13-inch tires aren't as plentiful as they were 30 years ago. Honda installed 14-inch wheels on the same basic chassis with the Prelude Si, though, which will give you a bit more of a selection. You could even try 15s, although I think that wheel/tire combination would be a bit heavy. Then go for a good set of shocks. I favored Tokicos when I had mine, but KYB makes a good set as well. If you really must, you can install a heavier set of sway bars, but start with the shocks and drive it a bit. This was judged as the best-handling front-wheel drive car in the world at the time, so tinker carefully.

Re: engine swaps

By as I go I mean, for example the brakes. I had know Ida how to replace the roter and caliper so I had to learn as I went. And thank you.
Like I think I said in planning on getting the car back in shape aka rust,leaks,paint.
Any advice on those would be nice, its leaking from the roof when it rains.
But since I have done the tune up I don't really plan on messing with the engine, although yes I would like more hp, I am pretty happy with it now. Other than the fact I need a new exhaust because mine is "gone".

Ouch -- is it coming in around the moonroof, or somewhere else? Could be a window seal, or maybe a plugged roof drain. Another good reason to download the shop manual -- it'll help you track that down.

Doing bodywork hasn't changed much over the last couple of decades. Grab a book on basic bodywork, see what reminds you of your car, and that'll help you plan what to do. 2d gens seem to be susceptible to rust on the trunk lid, but if it's surface rust, it's a fairly easy repair.

Re: engine swaps

Has to be going somewhere. How many miles between the times you have to add oil?

Is it going out the tailpipe as smoke?
Leaking out somewhere? (Take the plastic underside tray off and put some cardboard under the car overnight.)
Into the coolant? (Look at the coolant -- if it looks like a chocolate shake, you have problems.)
None of the above?

Re: engine swaps

That's not good. Look at the areas I suggested, and tell us what you find. Look around the crankshaft and camshaft seals at the end of the engine to see if they're leaking...sounds like you're leaking. The only 4-cycle engine I've seen burn oil at that rate is the old engine in my truck (40 miles/qt), and there was no doubt it came out the tailpipe!
