Which motor mounts do I use with the QSD H2B kit?
QSD's H2B kit utilizes the corresponding B-series mounts pertaining to your chassis. With our concept the transmission does not relocate and therefore all mounting positions are retained around the tranny. Kits includes an engine mount bracket specific to your chassis that will use 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. We would not advise exiting B-series owners to use decade old mounts with any performance application . At the minimum urethane inserts should be used and we highly recommend using any of the major aftermarket B-series mount kits available.
Which rear L-bracket do I use?
The same L-bracket used with a B-series 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 work! From the flywheel out, everything is B-series. You cannot use an H-series flywheel. It will not fit within the B-series bell-housing.
Is the position and length of the axles or shift linkage changed in any way?
No. The transmission does not budge, so neither do the axles or shift linkage.
So what has to remain from the H-series drivetrain?
Nothing. Our H2B uses entire B-series drivetrain from the flywheel out to the axles. It really is a simple 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 engine adapter plate work with an F-series block?
Yes. F22, F23, F20B... and all H Blocks.
Does the kit work with the later model SH blocks?
Our adapter plate will bolt up to any H-series engine. However, the new SH blocks used with the ATTS transmission were designed with a different block casting than the rest. 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 clearance an issue with all chassis’?
Yes. This is the sacrifice you have to 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.
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 a solid 3 inches of clearance in a Rex. And no, the SIR hood does not even come close.
EK guys are the lucky ones. The hood will close completely without spacers.
What must be done to the drivers side framerail?
Framerail modifications must be made in all chassis’s to gain the clearance needed 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. There are no future plans to make them for the Prelude/Accord chassis'.
