Firstly, it's had an engine conversion to an EFI Vitara 1.6 (I don't know the engine code, but I check if that's needed) but it is using the stock 5 speed Sierra gearbox.
This has caused what I'm told is a common issue with this swap, the clutch makes a bloody awfully loud vibration noise around 60 - 80 km/h.
The owner told me he had it investiaged by a mechanic and he believed it was caused by a tiny tolerance being out between the two, but that no damage is being caused.
Regardless, I want to use the Sierra as a daily, so I plan to fix this.
It has a XTD clutch in it at the moment, but I was looking at putting in an Exedy.
My question is, to fix this tolerance do I get a vitara or Sierra clutch, or is there more to it?
This is not a common issue at all, in fact, I've never heard of it. Two of the four bell housing bolts align between Sierra and Vitara, so it's not possible to misalign the engine and gearbox. (if that's what the mechanic was referring to)
A vibration at a road speed (regardless of gear) is extremely unlikely to be associated with the clutch. Its most likely associated with the jackshaft, transfer case or rear driveshaft. My guess is the jackshaft universal joints need replacement.
If the vibration is associated with engine speed ( so not related to road speed or selected gear) , it could be associated with the input side of the gearbox. Dipping the clutch should make it disappear. Is it a fast "thrumming" type of vibration? does it make the gear lever and transfer level jiggle? Does it get worse with more torque (is in lower gears/more acceleration?)
Quote: Second question; it has 31" inch Silverstone extremes on it, while very impressive off road, as I said before I'd like this to be my daily so I put some 29" a/ts off my feroza on it however the front left rim was rubbing when turning to the right on the steering knuckle.
Both are 15 inch rims, but the Silverstone are wider. I should also mention it has an aftermarket Superior Engineering chromly steering set up.
Any ideas here? I can report back with both exact sizes.
This is a bit confusing. The rim and steering knuckle always move together as a unit, so if it's rubbing at right hand lock it's rubbing straight ahead. If in fact the contact is between the tie rod or drag link and the rim, that would be understandable. In this case, the feroza rims have incorrect offset to clear the bulkier superior tie rod/drag link.
Quote: Last question I'll ask, I have more but don't want to ask too much in one thread...
Neither the stock water temp gauge or the aftermarket one it has read anything, even doing some pretty decent crawling it sits at the lowest.
Most likely was never connected/changed over when the new engine was fitted, but without photos/more detailed information I can't say more than that. You definitely want a gauge connected though, depending on how the cooling system was setup, overheating is possible and these motors are prone to crack if they get hot.
