IF your car was EX, you will only need to add wiring for the IAB and the knock sensor. If your car didn’t come with VTEC, you’ll need to add the wiring for the air intake bypass (AIB), knock sensor, VTEC oil pressure sensor and VTEC solenoid. Extend its red/yellow and green/white wires to fit. The intake air temperature sender is located at the end of the intake manifold on the h22 vs. You can keep the same pins but swap out the plastic connector.
While on the EGR wires, change the connector from the accord’s 3 pin square connector to the preludes round one. the h22, the coil, EGR and fan switch circuits need lengthening. Because the distributor is closer to the coil on the accord vs. Same wires, different location to fit around the h22a. The vehicle speed sensor plug gets moved from the front to the back in the engine, near the O2 sensor plug. To accommodate the EACV plug and its yellow/black and blue/yellow wires gets moved to the center of the injector harness. The electronic air control valve is located near the middle of the fuel rail on the h22 rather that near the throttle position on the F22. The oil pressure sender wire, while still using the accord plug, gets extended 5 inches to reach the H22’s sender. To tackle it yourself, get the two engines side by side, add a tasty beverage and get familiar with these mods. If you go the easy way, you’ll get a modified Accord harness and a separate sub harness, which connects the unique ***** guts to the h22a ECU. Hasport also makes one that’s plug and drive. To prep the wiring harness, there’s enough soldering to kill half your brain cells, and plenty of work to stress out the survivors.

Or keep your eye out for Hasport-produced mount that will adapt the autos frame rail bracket to a manual transmission. If your car started automatic, you’ll need to weld the manual transmission bracket (Honda P/N 60831-SV4-970ZZ) to the right frame rail in place of the automatic part. Either the Accord of the Prelude rear bracket and mount set ( no mixing and matching between them) can be used but the Prelude parts are stiffer and a wiser choice. You’ll have to use the softer accord front mount because the stiffer prelude mount is the wrong height – bummer.
#Accord cg engine swap cracked
A few decent launches will finish off any old and cracked mounts and its too easy of a job to pass up when the engine is out. It’s a good time to consider the original mounts you’re reinstalling (hint, buy new mounts). The other three mounts are based on original parts. The Hasports part is solid aluminum and comes with a polyurethane bushing, which reduces engine movement but increases vibration compared to stock rubber. Getting the H22 bolted in will require cutting tweaking and general rearrangement of the stock left side mount, or the purchase of Hasports part for this swap. With the two engines sitting side-by-side you’d be able o quickly piece together all the right bits. Our H2 came complete from HAP Recycling, ad it was from a 94 Prelude-perfect. Our swap victim was a very sleepy looking ’94 LX with five speed. Removing the radiator will the engine compartment less cramped, especially if you’re working through the top of the engine compartment, Honda radiators have plastic end tanks that wont hold up to a swinging engine. Keep in mind that a lot of pieces are being reused, so its time well spent making sure you have everything unhooked before you move the engine. With compressor removed from the engine, string it up to the lower radiator support to keep it out of harms way. The Trick is to keep the A/C system intact and in the car (including the compressor) during the swap to avoid having to refill it. The F22 can be removed from either the top or the bottom, but dropping it from the bottom is easier if you have a lift and engine dolly at hand. You’ll spend less o it than all the parts you probably break if you don’t use it. The fundamentals to swapping a '94 Prelude H22A engine into a '94 accordĪrticle Taken from “Honda Tuning” magazine featured February 2004Ĭommon sense dictates that you should arm yourself with a factory service manual.
