Procedure
All engine mount brackets need to be cut from the body
The right side chassis leg needs about a 10 inch section completely cut and removed from the car (this will cause flex too)
The exhaust manifold will not fit, you need to have a very slim manifold made to make the engine fit
The front crossmember needs to be trimmed to allow the hand made manifold or headers pass.
You need to make a custom mount bracket for this.
No axle shafts will fit - you need to make yourself special shafts and ends to accomodate the original hubs.
No original mount will fit and you would need to make a mount bracket on the right chassis leg that you cut previously.
The engine will be jammed right up against the firewall - you might need to hammer it inwards.
have a look
The hand made engine mount bracket and the black cover is the hand made heat shield for the hand made exhaust manifold.

I did this in a 3G accord which was a complete basket case hence we had nothing to lose. To stiffen the chassis leg an additional brace was made to tie it across and also a chassis brace was made and bolted under the car to stiffen the entire body.
The original brakes are tiny and need upgrade - the larger brake hubs for this car do exist and were shockingly expensive as they are very rare - I got them from Thailand.
The wiring is very involved if you want a clean job - I routed the wiring like the original 3G came - the wiring enters from the left fender and not the firewall. - I did this car's wiring myself - it had absolutely zero wiring, I built the harness from scratch - to do this nicely you will need to remove the dashboard and install the wiring nicely - I tucked the main relay next to the ECU and used the internal fuse box "starter" and radio fuses for the start signal and ECU live.
This swap also had a working A/C all properly wired up into the original system.
This was a long time ago too and that engine you see is an F20A
btw - you will need a prelude/accord cable select shifter box, shift cables and have to make a hole in the floor for the cables, you will also need to rework the clutch to hydraulic (easy when dashboard is out)
