CAN THE ENGINE BE DROPED FROM TOP TO BOTTOM INSTEAD USING A LIFT? USING JUST AND ENGINE LIFT AND A LEVELER????
I was thinking about using 2 heavy duty floor jacks or something like that!
I drop the engine in the engine bay with a chain fall.... It's tie but easy enough to drop. Just be carreful not to kinc the fuel line, everything else pass easy. Start to bolt the rear mount (the one go on the subframe) in the bracket (big black one) and the passager side mount on the engine... Drop the engine, bolt lightely the passager mount on the car...adjust the driver side one. Tight the both mount. And after that bolt the rear one on the subframe.
I don't understand why...But Integra Axles 94+ only fit on the passager side. On the driver side, it spend is time to go tou from the tranny. It need at less 1 inches more. I try a Civic Si 02 one, but I still have the same trouble.
Because I don't have ABS the RSX axles fit well
The engine is in is place...It's impossible to be 1 inches beside...
my driver side axle was too long. i had to get a spacer to fill the gap. it was only a couple of threads but i didnt want to mess up the knuckle.
dont know what to tell you. try maybe an rsx axle with the civic si end piece. maybe they are longer. dont know why they would be but like i said, mine fit fine.
Okay.. for those of you that would like to add in your 2 cents on how to do the k20 swap(for those of you that did it) then that would greatly be of help to everyone on this forum that either wants to do it or in the process of doing it themselves (and might have some problems)... basically it comes down to this.. i have already posted (its stickied up top) the wire harness that you need to rewire for the k20 wire harness to work on in a d17 (courtesy of dark2k1)... plus with the addtion of adding extra wiring for the 02 sensor which the d17 clip doesnt have... so what else has everyone else come into along during the swap that everyone might encounter and how to fix it??... as far as i know is the swap is straight forward with the modification of clip C101..... plus thae addition of adding the thermostat wiring and other stuff... so who has a complete everything done??... and dont say buy a wireharness thats already made.. the purpose of DIY is to learn for yourself and to save money... HAVOK says to ask the wiring questions in the I.C.E./ Electrical section but why bother when that section is basically all audio and lighting stuff anyways..

The K20A3 does not have a standard DOHC VTEC valvetrain as we know it from the B-series engines - the K20A3 should actually be called a "DOHC i-VTEC-E" engine, because it uses a VTEC-E cam setup. The K20A2 is the "real" DOHC i-VTEC engine, utilizing the standard DOHC VTEC cam setup we're all familiar with. To help you understand the differences between the K20A2 and K20A3 engines, I've included the following information from a post I made elsewhere:
Allow me to evaluate. Let's start out by defining some terms:
VTEC - Variable valve Timing and lift Electronic Control. At low RPM, a VTEC engine uses a normal cam profile to retain a smooth idle, good fuel economy, and good low-end power delivery. The VTEC mechanism engages a high-lift, long-duration "race" cam profile at a set RPM value (i.e., ~5500RPM on the B16A) to increase high-end power delivery.
VTEC-E - Variable valve Timing and lift Electronic Control for Efficiency. This system isn't really VTEC as we know it. At low RPM, the VTEC-E mechanism effectively forces the engine to operate as a 12-valve engine - one of the intake valves does not open fully, thus decreasing fuel consumption. At a set RPM value (i.e., ~2500RPM in the D16Y5), the VTEC-E mechanism engages the 2nd intake valve, effectively resuming operation as a normal 16-valve engine. Note: in a VTEC-E engine, there are no high-RPM performance cam profiles; this engine is supposed to be tuned for fuel economy, right?
VTC - Variable Timing Control. This is a mechanism attached to the end of the intake camshaft only which acts as a continuously variable cam gear - it automatically adjusts the overlap between the intake and exhaust cams, effectively allowing the engine to have the most ideal amount of valve overlap in all RPM ranges. VTC is active at all RPMs.
i-VTEC - intelligent Variable valve Timing and lift Electronic Control. This is a combination of both the VTEC and the VTC technologies - in other words, i-VTEC = VTEC + VTC. Currently, the only engines that use the i-VTEC system are the DOHC K-series engines.
Now this is where things get tricky - Honda uses the term "DOHC i-VTEC" for two different systems: The first system is used in the K20A2 engine of the RSX Type-S. The second system is used in the K20A3 engine of the Civic Si.
The First System (K20A2):
This system is pretty close to the older DOHC VTEC engines. At low RPM, the K20A2 uses a normal cam profile to retain a smooth idle, good fuel economy, and good low-end power delivery. At 5800RPM, its VTEC mechanism engages a high-lift, long-duration "race" cam profile to increase high-end power delivery. The only difference between this i-VTEC engine and the older VTEC engines is the addition of the VTC system. The intake camshaft has the automatic self-adjusting cam gear which continuously optimizes valve overlap for all RPM ranges.
Here we see an image of the intake cam lobes of the K20A2. Notice there are 3 lobes; the two side lobes are the low-RPM profiles, and the center lobe is the high-lift, long-duration profile which engages at 5800RPM. Basically the same setup as the old VTEC engines we are familiar with.
Now here we see the VTC mechanism - the gear on the end of the intake cam that adjusts valve timing (overlap) automatically on the fly.
This system is used in engines powering the JDM Honda Integra Type-R, Civic Type-R, Accord Euro-R, and the USDM Acura RSX Type-S and TSX.
The Second System (K20A3):
This system does not really conform to the "DOHC i-VTEC" nomenclature, as Honda would like us to believe. As I mentioned in my previous post, it actually should be called "i-VTEC-E," because it uses a VTEC-E mechanism rather than a standard VTEC mechanism. At low RPM, the VTEC-E system effectively forces the engine to operate as a 12-valve engine - one of the intake valves does not open fully, thus decreasing fuel consumption. At 2200RPM, the VTEC-E system engages the 2nd intake valve, effectively resuming operation as a normal 16-valve engine. There are no high-RPM performance cam profiles; this engine is tuned to balance fuel economy and power, rather than provide pure performance. On the intake cam, there is the VTC mechanism which basically is an automatic self-adjusting cam gear used to continuously optimize the valve overlap for all RPM ranges. This being a VTEC-E system - and not a true DOHC VTEC system - is the reason the K20A3 redlines at a measly 6800RPM, while the K20A2 is able to rev all the way to 7900RPM.
Here we see an image of the intake cam lobes of the K20A3. Notice there are only 2 lobes - there is a nearly round one used only for the low-RPM disabled intake valve, and then there is the regular lobe used by the other valve at low-RPM and by both valves at high-RPM:
This system is used in engines powering the USDM Acura RSX base, Honda Civic Si, Accord 4-cylinder, CRV, and Element.
Special note: The K20A3 engine used in the Acura RSX base has a slightly different intake manifold design from the K20A3 engine used in the Civic Si. The RSX engine uses a dual-stage manifold, similar in concept to the manifold of the B18C1 in the old Integra GSR. It uses long intake runners at low-RPM to retain low end power, and switches at 4700RPM to a set of shorter intake runners to enhance high-end torque. This accounts for the extra 9 ft-lb of torque in the RSX (141 ft-lb, vs. 132 ft-lb in the Civic Si).
Here is an image showing just how this dual-stage manifold works. On the top, you can see the low-RPM (long) runners are in use, and on the bottom, you can see the high-RPM (short) runners in use.
Myths:
1. The i-VTEC engine engages VTEC gradually, and not suddenly like in the old VTEC engines.
Wrong. The i-VTEC engine "engages VTEC" at a single set RPM, like always. Whoever started this rumor is a ****tard. Read the definitions above.
2. VTC engages at a set RPM.
Wrong. VTC is always activated. Read under "VTC" above.
3. The K20A3 engages VTEC at 5000+ RPM.
Wrong. Technically, there is no "VTEC" (as we think of it) in the K20A3 engine - it uses a VTEC-E technology, which engages at 2200RPM. Read under "The Second Sytem" above.
