Ok now here it is, I have a UZZ31 that has 330xxxKms on the clock and I now have a bit of cash to throw at it.
It is my daily driver but I would like to be able to take it to track days.
Now I all ready have a LSD and a cat back exhaust along with a mechanic that is my brother.
I want to find out some ways of getting more performance preferably with little cost. I would like to put go before show how ever it is my daily driver so some creature comforts I would like to keep.
First off I am getting some new JZA80 supra brakes for the front and considering braided lines while i'm at it, so this leads me to ask are the lines worth it remembering that my car has done so many Kms? Here is a link for some on trade me
http://www.trademe.co.nz/Browse/Listing.aspx?id=218907249
Secondly is some extractors, now I have tried multiple times to contact Neil Griffiths on purchasing some but keep getting no reply, so if you read this or any one who has regular contact with him please pm me asap.
Now this is where I ask you guys for some help as to what other modifications besides a BFI could I do to get some more oomph?
I am considering buying another engine with lower Kms and doing a straight swap but also getting some performance cam shafts to go in http://www.camshaftshop.co.nz/index.php/1UZ-FE/207-D-Camshaft/camshaftshop_view.tpl.html I would also buy the springs to go with them.
Getting these I will need a ECU upgrade as well so that then leads me to ask, HELP what do I do? I could go to a place in Rotorua called Choke On The Smoke Racing and find out if they could point me in the right direction. Would I be able to get away with a piggy back? Or would this work? http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Performance/Electronics/auction-21859 2250.htm This is from Choke On The Smoke.
Would upgrading the stock injectors help and/or be needed? If so what would I be able to use?
So that's that as far as the engine is concerned for now. Of course a new cam belt/ water pump will also be done. My old a/c compressor is stuffed so that is on the cards as well as a re gas.
Now over to the suspension set up.
I would like to ditch the factory TEMS in favour of making my car a little lighter and getting some adjustable coilovers, perhaps these? http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Performance/Suspension-braces/auction -219443906.htm Now how much of a mission is this and is there any thing else I need to consider? While i'm at it I would like to do the bushes too since i'm getting squeaking coming from my suspension and since the amount on Kms. What do you recommend in the way of bushes?
Now on to the wheels. I do currently have some 17 inch TOM'S racing wheels but would like to go bigger for more traction. Now considering the brakes what type of offset would be best? I have looked at other discussions about this and see there are mixed opinion's. I know that tram lining is'nt good for road use but bear in mind there will be track use here. I have spied these again on trade me http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Wheels-tyres/Alloy-wheels/auction-218 802968.htm or these but wider rear's http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Wheels-tyres/Alloy-wheels/auction-219 126062.htm
Being so old there are also some other things that need replacing, like a new driver's door card with arm rest and some new head light's and tail light's. I think I might go for some after market one's http://cgi.ebay.com.au/TAIL-LIGHT-FOR-TOYOTA-SOARER-LEXUS-SC300-SC400-SMOKE_W0QQitemZ370201133653QQc mdZViewItemQQptZAU_Car_Parts_Accessories?hash=item370201133653&_trksid=p3286.c0.m14&_trkparms=66%3A2 %7C65%3A1%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50 and http://cgi.ebay.com.au/PROJECTOR-CCFL-HALO-HEADLIGHT-FOR-91-1999-TOYOTA-SOARER_W0QQitemZ110392089752 QQcmdZViewItemQQptZAU_Car_Parts_Accessories?hash=item110392089752&_trksid=p3286.c0.m14&_trkparms=66% 3A2%7C65%3A1%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50 but in the black.
After all the mentioned items I will be looking at some where around $10000 or more so any tips or help to reduce this would be greatly appreciated.

Remember I am not keen on going for forced induction, just mildly tuned. Also any parts recommended could you include where I could get them and part numbers if possible.

I know this is a big ask so thank you for you're time.

I don't have much advice other than try and stick to known name coil-overs. I've never even heard of DC before.

Are you looking at having a road legal car (ie registered) and using it on the track?

James, having a 31 myself and pumping a sh1t load of money into it, with intentions of putting it on the track, I thought about just buying a uzz30 and starting from there. (keeping or selling the 31).

What's that about bigger than 17" wheels giving more traction?

Had a look at the really big wheels with extreme low profile tyres used on Formula One recently?

It seems we are destined to clash today, Pen.

A larger circumference tyre (tyre, not rim) will put more rubber to the ground. BUT it is not that simple. I was humbled by an AUtospeed article recently that taught me a whole lot more than I thought I knew about tyre size and available grip, contact patches and heat sinks etc.

SO, a larger diameter rim, with a lower profile tyre (to keep the same circumference) will probably not get you more traction, unless you go wider, or better quality tyres that are available in the larger sizes.

Ben, I don't see any clash. :-)

Did anyone see Top Gear Australia this week?

They had a hot supercharged Holden which went 3-4 seconds slower with bigger wheels (and brakes).

It's the low profile that is the problem, less sidewall flex, so less able to maintain contact on either rough surfaces or when cornering.
