I have searched quite a bit, but get a lot of static and none of the detail I want in the results.
I have an 88 model CRX ED9
I am completely stripping down and rebuilding everything including body, paint, trim, engine transmission and suspnsion as a fast but comfortable daily driver.
I hope the engine will finally be a D18 DOHC with a moderate size turbo to give about 250 hp on 98 octane pump fuel with maybe a potential to turn it up to 300 or so on methanol or race gas.
I am still slightly contemplating a RT4WD conversion as I have some parts, but weight and durability and spare parts issues have me concerned. I really don't know how tough or heavy a 1988 Civic RT4WD gear box and rear diff are, although it would add a real cool factor.
I will retain P/S & A/C etc for comfort, but I like very crisp direct response re handling and roadholding.
I am considering upgrading bushes, engine mounts and traction bars.
I intend to drag race occasionally, do club events like track days and amateur rally days etc.
My normal driving is mainly suburban main roads and highway for private and business, but there is enough rural back road and dirt road to give me some real rally type fun at times.
The car needs to be an all rounder.
I need to retain stock or near stock ground clearance.
I need to retain reasonable in cabin noise levels so my cell phone hands free kit works good as this is also my business car.
I don't want to give away ground clearance or load carrying capacity, in fact I need to retain an ability to carry a heavy load in the back compartment, like some tool boxes or engine parts for other bigger cars.
Will filling my mounts and bushes transmit to much noise or clonks and rattles to the cabin. I plan to just use a real good hard grade of RTV silicone rubber over OEM mount rubber. Is this how it's done.
Will traction bars transmit extra road noise or clonks and rattles. Will the spherical joints have a short life.
Does anyone know what diameter and wall and grade of tubing is used for a good rigid traction bar cross member.
Does anyone know what size radius rods & steel grades are used for radius (trailing) arms (rods).
If I use them I would plan to fabricate them myself rather than to try to import to Australia, but a clue on spes of current good designs would help as a starting point.
My guess is about 2" chrome molly medium wall tube for the cross member and about 1" chrome molly heavy wall tube for the radius arms. Attachment tangs to be gusseted and about 2mm plate.
Sorry for the long post and multiple questions.
