Hey guys,

I think it's finally time to start the process for a motor AND transmission swap for my '91 Prelude Si. The car currently has a B21A1 with an automatic transmission. I'm looking to go for a H22 swapped from a 92-95 Prelude with a 5-speed manual transmission. I'm in the process of researching and sourcing out my parts, so that I can collect them and make the actual swap process as smooth as possible. I'm planning on taking the project to be done at a shop, and let them handle the rest. Side question: would this be the same if I went for a F20B motor swap?

I'm following a thread posted by Sean (1FunRyd): The Official H22 Swap thread by 1FunRyd - Honda Prelude Forum
I'm using it as a reference guide to have an idea of what essential parts I may need for the project to be successful. I would like some opinions, suggestions, and or advice on the parts that I gather or what to keep in mind. The purpose of this thread is for discussion on helping me (and maybe others) in the process of a swap project.

The motor mounts I’m looking to go for is the ones from Innovative: 88-91 PRELUDE CONVERSION ENGINE MOUNT KIT (H-Series / Manual)

What do you guys think about it? Just fine?

Also is this bracket necessary? H22 ALTERNATOR RE-LOCATOR
Stay away from the innovative products. They are terrible due to the fact that they do not sit the motor and transmission correctly in the engine bay.

Many have went with them due to they are cheaper than my kit but my kits fits the engine in correctly and allows for powersteering, the innovative does not.

The traction bar also has fitment issues, I know this because I fixed one innovative swap kit already and the first buyers of the kit and the traction bar kept calling me to help them fix innovative s issues.

Also to make things less costly for you, stay away from the F20b.
I used to be an advocate for it, but after researching and even witnessing the extra costs to get the motor to run correctly you end up losing in the end.

Just stick with a JDM H22a swap, you will not regret it.

Honestly you could not go wrong buying Dustin's lude.
$5k for a build that is worth way more and you are already ahead of the game.

07/07/20 Update:

Because of this whole pandemic going on, there have been delays, and I have been waiting on some parts to be delivered while getting ready to order more.

Right now, I have:
-Intermediate Shaft/Half Shaft/Mid Shaft from a manual '96 Accord (94-97)
-90-91 Prelude manual pedal assembly
-Rear Engine T Bracket from a '94 Prelude
-90-93 Accord manual trans shifter & cables; linkage
-H22 motor mounts from 1FunRyd

Waiting on:
-Engine Wiring Harness
-Traction Bar
-Skid Bars

I'm about to order these 90-93 Accord manual axles from 1A Auto, but I just wanted to quickly confirm and verify if for any reason I need the Hub assemblies included with it?
90-93 Accord Manual Axles (without Hub assemblies)
90-93 Accord Manual Axles (with Hub assemblies)

Let me know if I'm good to go with just those axles! Thanks!

Do not buy the hub assemblies. Those will not fit our chassis. The axles will work for the swap but not the hubs.

07/23/20 Update:

Right now, I'm trying to figure out the whole clutch master cylinder and slave cylinder situation. I already have a clutch master cylinder for the '91 Prelude from Duralast and an Exedy slave cylinder (SC642) for 1997-2001 Prelude. I need a little bit of guidance on the clutch lines. What I'm trying to figure out, specifically, is the clutch lines from master cylinder to slave cylinder. Since my car is an automatic going to a manual, I don't have anything ready, and I'd have to manually buy almost every small piece to get an OEM line going.

BUT, I was wondering if I could buy this clutch line kit from Rywire instead to replace the whole factory line from master to slave cylinder:

Rywire Accord & Prelude Hydraulic Clutch Line

58 inches from clutch master cylinder to slave cylinder? Will that be okay?

Here's my reference to see what I would order if I went for an OEM factory line: 1991 Prelude Clutch Master Cylinder

I heard that S2000 clutch master cylinders fit our chassis and might be a better option since I don't have to play around with mounting the reservoir a little different on the 3rd Gens. I might want to get this S2000 Clutch master cylinder kit from Rywire:

S2K CMC Kit w/ clutch lines

What do you guys think?

The S2000 MC is your best update for a cleaner look and ease of swap.

11/12/20 Update:

So, as of August 6, 2020, I had just about everything ready but the motor and transmission. Because of the pandemic, the project got delayed and took longer for everything to get started. I ordered an H22A1 from JDM Worldwide Auto Parts, Inc. in Jacksonville, FL. The motor looked fine, but we didn’t realize at first that the valve cover had a crack/hole that might’ve exposed the inside some. Maybe that’s why they sent us an extra valve cover without us knowing. We got the motor and tried turning it over from the crank on October 29. The motor was seized and locked up pretty badly (maybe because it’s been sitting for so long), so my mechanic and I decided that we didn’t want to deal with this motor any longer. Maybe there would be some rust or corrosion build up that could cause more damage if we kept messing around with it. I wasn’t comfortable with putting this motor in my Prelude to have problems come up later down the road. Just a quick message to those who are reading through the forums and are looking to order these older motors or anything from Jacksonville, Florida, I advise you guys to be cautious and maybe do a little research on who or where you order from.

That being said, I’m moving on and have been struggling to find another H22, preferably an OBD1 H22A. Numerous phone calls to warehouses around the east coast, motors selling out left and right. I remember calling and just getting ready to order a motor, but in a matter of 15 minutes, the motor had been sold. Now, I’m waiting on a motor from HMotors Online. Hoping to finally get this swap project started by the end of the year. Will keep you guys updated!

Also, shoutouts to Sean (1FunRyd) for helping me with the bits and pieces for the project! Appreciate that dude.
