yup, getting some of my office Graphic Designers to do that form me.

I think i figured out the peppy steering at high speeds.

Caster got fouled

Here i got this from about.com

"Caster is the tilting of the uppermost point of the steering axis either forward or backward (when viewed from the side of the vehicle). A backward tilt is positive (+) and a forward tilt is negative (-). Caster influences directional control of the steering but does not affect the tire wear and is not adjustable on this vehicle. Caster is affected by the vehicle height, therefore it is important to keep the body at its designed height. Overloading the vehicle or a weak or sagging rear spring will affect caster. When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a more positive caster. If the rear of the vehicle is higher than its designated trim height, the front suspension moves to a less positive caster. With too little positive caster, steering may be touchy at high speed and wheel returnability may be diminished when coming out of a turn. If one wheel has more positive caster than the other, that wheel will pull toward the center of the vehicle. This condition will cause the vehicle to pull or lead to the side with the least amount of positive caster."

The back of my car has been raised a bit, so hypothetically if the front has been raised more than the back, I get a more positive caster that stock i.e steering gets touchier at high speeds.

Caster is adjusted during wheel alignment, unless you didn't do it before.

Goose, What were you doing near ITC?? That is like my everyday hangout spot...

[Sprucegoose]

I work at MTV, its right there...
in fact in in office right now, chilling.

There is NO Caster /Camber Adjustments on an OHC. Putting a lower diameter tyre in rear will raise car from front & theoretically you will get more +ve Camber Effect, but how much that will need to be measured.

[Sprucegoose]

@ Ford Rocam: so it can't be caster then...
Damn i thought i was onto something..

[danlalan]

Finally done eh! Looks like its time for another ohc meet.

Congrats! The car is lookin' good.

The OHC is wafer light and has an extremely basic suspension design; it's known to get nervous at speed. Plus, the Marine Drive surface quality is very uneven and its easy to tram line.

How come you got yourself a 1.3 in the first place, if such a long list of mods was in the pipeline?

Haha.. when i got the car i didn't know what even VTEC was.
I was new to cars.
I was so new in fact that i didn't know there there was a facelifted [Type II] model or a 1.3 & 1.5 variant.

Right now a 1.3 is peppy enough for me.

But Down the line may get an engine swap too.

All Depends on how much i can save

Does it tend to dart from side to side. It could be wheel alignment ie, you have too much toe-out. Get it checked and inc the toe-in.

[Sprucegoose]

@Mpower: Will check, but yes the steering does dart from side to side, even at normal speeds. But at high speeds it gets scary.

If I get it re-aligned and set it to toe-in, will that improve its line holding abilities?

Better get a proper exhaust fitted before you bend the valves thanks to your short pipe. Adman from the forum also had a shortpipe from game over and he did face valve problems.

yes, the darting and nervousness is an indicator that you have too much toe out. Check it and compare it with specs. All cars specify a little toe-in.

nicely done up car man. i liked the car specially the black wheels.

[ssjr0498]

Hi..

can you please explain!! What are you reffering too!! how is a short pipe damaging the valves, you mean are the headers very very restrictive? Increasing the back pressure...hence damaging the valves!!
