My main concer about a rwd front mount is traction

I like this job very well http://www.simon-stubbs.co.uk/ check out the blue V8 mini :twisted:

but due to our laws I think a stock 1.6L or 1.8L mounter in the back would have to do

I've measured and compaired a bommodore 3.8L V6 and I reckon I could squeze one of them in a rounde (mod fire wall 100mm back) but then again...traction :evil:

with that blue v8 mini, it has a problem with lack of weight in the front of it, so it goes wandering. if i do drop the sr-20 in it, to help with traction, couldnt i increase the width of the wheels, and get a decent suspension set up?

^^^^^I'm not experienced on this but I think you can only increase the width of the track a couple of inches from standard. I don't know if that it is over all width of the wheels eg deep dish and realy wide wheels or if it's just the width of the hubs

someone please correct me.

I thought track is measured form the centre of the wheels. I may be wrong though.

i think you can only go an extra few inches in diameter. not sure about the actual width of the tyre, i.e how far in the wheel comes, not how high it goes.

This is one of those where there is a lot of rumour and inuendo about what's right and not . I'm still searching the RTA's site to find out for sure but I've been told that you can't increase the track by a set amount (I've heard 50mm and I've heard 75mm) unless it's engineered . The same with the wheel diameter and wheel width . When I find the appropriate bit in the rules I'll post the link .

OK , found it . This is from the NSW RTA website , http://www.rta.nsw.gov.au/registration/ ... 9_rev4.pdf and applies to NSW only though I'd say other states are similar . Track is measured from the centerline of the rim itself , not the wheel's center so rim offset will affect it as well

Quote:

Vehicles built to comply with ADR 24 (after 1/1/1973 for passenger cars)

Allowable rim width increase above the widest optional
Unladen weight wheel available for the axle assembly used

Up to 800kg 26mm (1inch)
801 - 1200kg 39mm (1.5 inches)
1201kg & over 51mm (2 inches)

Note: 25mm increase in wheel track limit also applies

Vehicles that were not built to comply with ADR 24 (prior to 1973 for passenger cars)

Maximum rim width
Up to 800kg 153mm (6 inches)
801 - 1000kg 178mm (7 inches)
1001 - 1200kg 229mm (9 inches)
1201 - 1400kg 204mm (8 inches)
1401kg & over 254mm (10 inches)

Note: 25mm increase in wheel track limit also applies

Also diameter of wheels -

Quote:

The outside diameter of the wheel and tyre combination must be no more than 15mm over the largest diameter
wheel and tyre combination specified for the vehicle and not more than 15mm below the smallest diameter wheel
and tyre combination specified for the vehicle.

so the maximum tyre width for a mini would be 6 inches. is that right, or is it an inch extra than the standard wheel?

6" for something built before 1973 , what was the widest standard rim used on a mini built after 1973 , 4 1/2" inch contessa's ? If so the widest you can go in a post '73 mini is 5 1/2" .

yeh that and hopefully a sound proof garage that will no doubt be filled by profanity. but i've decided on the sr-20, and i'm going to order a half-cut very shortly. if it fits, it fits, if it doesnt, i'll just extend it a bit more

I take it you mean the SR20DE and not the DET?

Then make sure you get the FWD SR20, like from the Nissan NX, Sentra or similar.

They also came out in RWD as well in the Bluebird, 200SX, S13,14,15 etc.

But, here's some advice that I hope you will take to heart............................

If I was putting an Nissan engine in I would opt for the SR16VE Neo engine instead. Its lighter, more compact, has VVTi and produces similar horsepower and torque to the SR20 engine, plus its only 1.6 litres as opposed to 2.0 litres. Here, check this out...........

"SR16VE N1 - Used in the VZ-R N1, which was a racing homologation version intended to compete with the Honda Civic Type-R. Producing 200 PS from its 1.6 L SR16VE engine, it claimed the highest specific output for a production car prior to the introduction of the Honda S2000"

That's my $0.04

Cheers,
Tricky

yeh i was meaning the de not the det. we were going to convert a van into a ute and drop the sr into it, and convert it into a rwd. i had thought about the sr16, only thought the sr20 parts would be cheaper and easier to come by, aswell me and my step brother dont know too much about that engine. what does it mean by "the highest specific output for a production car" output of what? hp torque etc?

thanks tricky, might look into it a bit more then. but i thought the de was "turbo ready" (for lack of a better word), but without the turbo. i thought the sr-20 was the non-turbo option?
