Hi guys
Ive got a 94 maruti tray that i use for a spray rig, the problem i have is that some jobs are far away so 4th at 70 max is no good (want 100k) but when i get to the paddocks i am only doing 20 in L4 can I change anything to help me with the prob or am i trying to have my cake and eat it too. Any ideas?
cheers

next time you buy tyres, get the next size up

hey fatzook,
What do you mean? Will changing boxes help?

You should be able to do quite a lot more than 70. My 1l Sierra (same engine and gearing) happily sits on 110 and will go off the end of the speedo with ease.

Does it only go 70 because you don't want to rev it any harder or because that is as fast as it will physically go?

If it's the former, hold it pinned. The 1ls love revs. Mine may be sitting on about 5500rpm at 110 but it's quite happy doing and will most certainly do it all day.

You can make a 5 speed by taking the gear set from a 1.3l Sierras gearbox and placing it in the Maruti gearbox casings, though I doubt the 1l will be able to pull 5th on anything but a flat surface, especially with the load you carry.

You wont hurt and F10a with revs, they aren't happy unless they're revving!

Sitting on 5000-6000rpm is perfectly normal with these.

Yes the F10A does rev and works well in the high rev range but I have seen a few with a conrod out the side of the block or with snaped timing belt due to a seized valve train, in the early days when we used to put them for our LJ's they were often killed trying to hold high revs for long periods like we were used to with our F8A and lower LJ gearing. I would be carefull about just thinking they are bullet proof and thrashing them, they are getting on in age. You may need to throw a tacho on it, they do sound like they are peak revving when they still have a bit in them.

A 5 speed 1 litre box is like hens teeth, gearing up with larger diameter tyres like Fatzook suggested may be your best option, my sons 1litre LJ on 31's runs along the open road like an angry bumble bee holding 100kph fairly well.
