Which motor mounts do I use with the QSDH2B kit?
Our kits utilizes the corresponding B-series mounts pertaining to your chassis. In short our concept does not relocate the transmission, no matter which chassis you are using it will stay in the same location as if the longblock was a B-series. Therefore the 3 mounting positions are retained around the engine and transmission.
Specific to the chassis being used, the kits includes an engine mount bracket which will be used with the corresponding B-series mount.
EF chassis’s require any aftermarket bolt-in-kit, or re-welded B-series mounts, just as if it was a B-series.
We DO NOT recommend the use of OEM mounts alone. Most B-series mounts are now decade's. Whether if you are shooting to build a H2B or a B-series NA performance build, just give in and purchase a set of good aftermarket mounts. With any performance application, upgrading your engine mounts builds strength into your entire drivetrain.
Which rear L-bracket do I use?
You will use the same L-bracket used as if is was a B-series setup within your chassis.
- EF uses DA - EG/DC uses DC - EK uses 99+ SI
Which flywheel and clutch do I use?
Any B-series flywheel and clutch combination will work. From the flywheel out, everything in retained within the H2B concept is B-series.
Our ARP flywheel bolts are at a length to work with an OEM thickness B-series flywheel body (the body is referring to thickness under the flywheel bolt surface and the face of the crankshaft).
Some B-series twin disc setups utilize a thinner flywheel body to accommodate room for the additional clutch disc. We can shorten the bolts to whatever value is needed. This can always be completed down the road if the twin disc route is chosen. Prior to installing the flywheel bolts make sure to measure your combined depth to assure there is adequate clearance.
You cannot use an H-series flywheel. It does not fit within the B-series bell-housing, try it and see.
Is the position and length of the axles or shift linkage changed in any way?
No. The transmission does not budge from the B-series position, so neither do the axles or the shift linkage.
So what has to remain from the H-series drivetrain?
Nothing! Our H2B concept utilizes entire B-series drivetrain from the flywheel out to the axles. It's really as simple as it sounds, and a very convenient conversion for an existing B-series owner.
So all I need from the H-series is the longblock and it’s components?
Correct.
Does the kit work with the later model SH blocks?
Our adapter plate will bolt up to any H-series engine. However, the newer SH blocks used with the ATTS transmission were designed with a different block casting. The rear of the block is completely different and does not work with our B-series intermediate adapter. It is possible to do, but you will have to weld the core mounts onto the block. It's been done, and will work.
Is hood clearancing needed with all chassis’?
Yes. There is the sacrifice you must make to optimize your drivetrain. Since the B-series transmission is not repositioned, the H-series engine will now sit in a slightly higher position compared to a conventional H-series hybrid.
DA, EG, & DC owners can run an OEM hood while spacing the rear hinges 1.5 inches.
The EF faithful are not so fortunate. A cowl style hood/or modifications will be required. You need to space the rear of your hood at least 2.5". And no, the SIR hood does not even come close. It helps, but you will still need to raise the rear of your hood.
EK guys are the lucky ones. The hood will close completely without spacers.
We are working now to create spacers that will make out look appealing. Hopefully you will see them from us shortly.
What must be done to the drivers side framerail?
Framerail modifications must be made in all chassis’ to gain the needed clearance for the alternator belt. A focus of engine clearance resides around the rear balancing shaft gear.
Running a smaller alternator belt from either the B/D-series engine will assist but still requires clearance to fit.
Prepare to drop your engine in and out a few times before satisfied clearance is obtained.
What other modifications are required on the engine?
You must also grind the rear of the block to create clearance needed for the drivers side axle. Instructions are included within our kit.
Does Quartersports make an H2B kit for any of the Prelude chassis’s?
Our kits are designed solely for the Honda Civic/CRX and Acura Integra chassis'. We have no future plans to make them for the Prelude/Accord chassis', sorry.
