    Jamie's Honda CRX race car

    Thought it was about time I posted some specs up for my car - I've gone on about it enough
    So, for anyone that's interested, bearing in mind it's a) Japanese and b) FWD...

    We bought the car in 2006, it was built for the CRX Challenge and Super Coupe Cup, both of which I am led to believe it won. I use the car for DMN and BARC, and my aged father campaigns it (slowly) in hillclimbs and sprints. The car is well used, but it was stupid cheap and up until we messed with the engine was uber-reliable.

    Did you know the B16 engine was the first production engine to make 100hp/ litre?

    The VTEC engine is very solid - NASP they will make 215hp on standard internals, and free rev to 9000. Ours is set to 8800rpm, which is good enough

    Shell & Panels
    1988 16v CRX Mk2, prepared by Barwell Motorsport. Was originally fitted with a D16 DOHC 1588cc engine making around 130hp, for the 1989 CRX Challenge.
    Fully seam welded
    Turrets strengthened and gussetted
    Engine mounts removed and rewelded (20mm back)
    Challenge spec cage, welded and bolted. Triangulated onto front suspension, stiffened at B posts
    Door inner skins removed
    Bonnet webbing removed
    Rear hatch stripped, upper and lower glass replaced with Lexan
    Rear side windows Lexan
    250mm deep chord twin element adjustable rear wing (now removed to avoid legality issues )
    Erebuni modified front bumper with custom splitter, lowered to 70mm ground clearance. Vented and ducted to engine/ brakes (not shown in pics)

    Mechanicals
    B16A1 1595cc VTEC DOHC, stock bottom end
    .040" head skim
    Mild polish
    Integra Type R valves, springs and retainers
    Skunk2 Pro2 Cams
    Piper adjustable cam gears
    Cropped cam cover
    Skunk2 Pro Series inlet
    Skunk2 70mm billet throttle body, port matched
    BMC CDA carbon air intake (ducted into front bumper) on Samco hoses
    B18 2.5" collector 4-1 exhaust manifold
    Custom 2.5" straight-through exhaust, single silencer in fuel tank well
    Y2 rebuilt transmission, replaced steel caged bearings and synchros
    Quaife QDF1U ATB diff
    Cerametallic Exedy HD clutch
    Custom Raxles driveshafts
    JDM PR3 ECU running custom maps, mapped realtime on a dyno/ wideband using BRE and Hondata.

    Suspension
    Bilstein adjustable height coilovers
    Various springs (currently 250lb front, 800lb rear)
    Spring preloaders and 'bottom out' stops
    Rebushed all round
    Welded and triangulated front upper strut brace
    Challenge rear upper brace
    Modified rear ARB, rehung
    Std front ARB
    Suspension travel limiters

    Brakes

    Yellowstuff pads
    Rear: Standard 16v CRX, EBC Green Stuff pads
    Wilwood adjustable bias in cockpit
    Silicone fluid

    Fuel System
    Custom 22.5 litre baffled aluminium tank, mounted inside cockpit on rear seat (tank has a 2l sump to avoid surge)
    Boxed, vented and splash bowl fitted, box top Dzus fastened down
    Walbro 280l/hr external pump

    Electrical
    Engine and car looms unpicked, stripped and rewound
    Varley Red Top 25 mounted on passenger floor
    Andersen Plug
    Headlights (full beam only)
    Rear lights
    FIA Approved Rain Light (ahem)
    AMB Transponder
    RollCentre Lap Timer
    Omex sequential shift light

    Interior
    Motodrive GRP seat
    TRS FIA harness
    Mountney Alpha wheel
    Dash top/ clocks retained
    Cutoff switches on carbon plates
    Lifleline 2.25l dual-area fire extinguisher

    Wheels and tyres
    Compomotive CX 6J x 14 rims (we have 14!)
    Avon 6.5/21.0/14 crossply (hillclimb)
    Dunlop SP 770 radial slicks (circuit racing)/ Avon A61 6.0/21.5/14 crossply
    Advan A032 SS (wets)
    Made 185bhp on a Dastek dyno, but a poor torque curve at the moment and an intermittent misfire. Projected to make 200hp once remapped.

    Probably loads I've forgotten too

      Head gasket went, it was pressurizing into the water jackets. It had a loose ignitor wire inside the dizzy too, which explains the misfire. Oh, and the head gasket blew the water pump gasket too. In the end it blew a hose off and everything was so hot it just made it impossible.

      Fixed now though

                      Re: Jamie's Honda CRX race car

                      I have to smile - the only problem with reliability is that we keep messing about with it!

                      In two years I had no engine-related problems, a loose battery terminal and a dead battery were the only issues, then a fried (stock) driveshaft. Since we modified the engine however, we have had:

                      Stripped gear in 1st (new tranny required)
                      Clutch
                      Head Gasket
                      Water Pump
                      Radiator
                      ECU
                      Crossmember
                      Ignitor pack

                      For the moment it is back on stock compression with stock cams, and it runs perfectly - it is making around 170hp in this form.

                      One of the reasons we like the car is the way everything is so beautifully engineered - all the bolts are zinc-plated with captive washers, cam caps, main caps and rods are numbered and directional to avoid incorrect fitting, gearbox magnet comes out almost clean every oil change etc. In stripping the cars we have cannibalised, there are almost never any seized studs and all the nuts come off without rounding out.

                      In short? It ain't the car that's bad, just the idiots puting it together

                        Did you do the lexan windows yourself or was that barwell Did they replace all the nuts and bolts with the zinc plated hardware?
                        The rear arb was rehung in a different position ? why ? any pics ?
                        Do you take it on the street at all?

                              used to rally a ex challange crx with d16 engine. never touched the engine apart from changing the oil.
                              fitted a quaife atb diff and it transformed the car.
                              used to be a bit tail happy until i realised the spacers used on the challange front brake set up gave it a wider track than the rear.
                              fitted rear spacers, played around with ride height and spring rates and then it really handled.
