89 CRX HF/ Beefed b18a1 swap
Heres what I know about the motor...
Block= bored .50mm oversize, shaved deck height .020mm
Crankshaft= LS Crank micropolished + magnafluxed for cracks.
Rods= Manley Sportsmaster.
Forged from aircraft quality 4340 material
Entire beam and cap are profiled to remove stress
risers and render the lightest possible rod
Shot peened after machining to Mil specs and 100%
individually magnafluxed
Cap fasteners are 7/16" ARP 8740 cap screws
Premium Ampco pin bushings
horsepower range for these rods is 800 H.P.
Pistons=Manley Platinum Series
2618 high strength material; lightweight design
Premium Chrome Moly pin included
Perfect ring groove to skirt squareness
Pressure balance groove
Premium Steel top ring sets and Round Wire locks included
Recommended piston clearance .0040" measured 1.100" from the bottom of the oil ring
Oil pump = OE Factory Acura new pump
All bearings= Cleavite
All seals = Comtect or OE factory
Cyl Head= all guides are new
All Valve are new Chrome valves
Timing belt new OE
Waterpump New OE
Camshafts= Stock
Cam Gears = Crower adjustable gear
So far I have...
ls 5 speed trans, flywheel,pressure plate
GSR Intake, exhaust manifold and fuel rail
Axles, ecu, harness
Engine mounts
cold air intake
JDM distributer
What I have ordered
skunk2 66 mm throttle body
skunk2 coilover/strut assembly
rear lower control arm, front upper control arm
new radiator and fans
plugs wires,tps etc....
My question is this.....
How should I set this engine up to be the most reliable daily driver? What fuel injectors do you recommend and would you change out the cam and springs to get the most performance from this motor?
Thanks in advance for you help.

Need more info. What's the CR? What fuel do you plan to run? How do you plan to bolt up the GSR intake manifold to the B18A1 head?

Yes, compression ratio for the pistons being used. The bolt pattern for the intake on a GSR is unique. Are you using a GSR head on a B18A1 block?

James, my mechanic was shocked the intake fit but didnt explain why.

Yea, I would def contact the previous owner for more details. It may be a high comp motor that requires 93 octane or higher or even E85. Also, find out if they assembled it with ARP head studs and/or rod bolts. A few more details, and we can point you in the right direction with the swap and tuning.

I'm buying the injectors and such this week. Would love some input here fellas. I totally trust my mechanic but would love to throw some ideas and input in his direction.

Re: 89 CRX HF/ Beefed b18a1 swap
**** man, I thought you were the mechanic. Owned by reading. Well, if your mechanic doesn't know if the motor has a GSR head on it or not, find another mechanic! Or do the swap yourself, and put the money you saved by doing the work yourself towards a good tune. Find a tuner and pick their brain on what cams and valvetrain components will suit your build best. You should also consult your tuner about the fuel injectors before you run out and buy some.

Re: 89 CRX HF/ Beefed b18a1 swap
lol James did tell me today the motor has a gsr head on it. Seeing that he has built around 30 or so I'm sure he knows what hes doing lol
Now could anyone give me an honest opinion on this motor? My biggest reason for the swap is I carry 4-500lbs in extra stereo equipment and I'm tired of being passed by rv's going up hill.
I'm not concerned about top end speed. Im more interested in the low end torque.

Heres a quick walk around of the car and and idea of the extra wieght I haul around.

My 9-5 job is building subwoofers for DC Audio and rolling to competitions on the weekend. Currently the loudest CRX on the west coast. Now I want to make it go fast and look good.

Thanks to the 2 gentlemen who replied. I guess I'll just leave it up to my boys at Lake County Car Audio in Upper Lake Ca.

Re: 89 CRX HF/ Beefed b18a1 swap
The swap will easily tote the extra weight and a 9.6:1 cr is boost friendly should you decide to add a turbo down the rode. I'm not a fan of body kits, especially when they're stuffed with chicken wire lookin' ****. But if I had to choose a kit, the Wings West kit isn't that horrible. Good luck with your build.

On the hood will be an ornate pic of Thorshammer Mijolnr with DC Audio on the sides. There will also be advertisements for Lake County Car Audio and Offroad (engine and suspension work ), Singer Alternators ( Hooking me up with a dual alt bracket for 400+amps of current), Kinetik Batteries(Battery Sponsor).
I'm still debating on what to run for DbDrag Finals in March but it will either be 2 or 4 lvl 5 12's, 2 9k amps, 3 multicell batts.
This is how i spend my weekends
