Specification

There are plenty of options with the Ultima. On the face of it the 17 stages only come to just under 15,000 plus VAT, but that doesn't get you a complete kit by any stretch. I don't want to go absolutely mad with the spec, but it's clear that building one of these it's important to make sure it's up to scratch, no point spoiling the ship for a ha'pennyworth of tar and all that. Some of the extras are performance/safety related, some finish related and some are creature comforts. Although you don't build a car like this with selling it in mind (well I'm not anyway) I know full well that at some stage I will want to sell it and having a high spec will hugely influence the saleability.

My initial order has comprised stages 1-11 and 14. Listed below are the additional items which are above and beyond the basic spec of the kit:

ItemDescriptionCost
Lowered Floor PanLowered floor pan to increase headroom for lanky gits like me!0.00
RAC Roll CageFull RAC spec roll cage in 38mmx3.2mm wall thickness CDS as single hoop but with hoop around windscreen braced back to rear hoop.920.00
Double SkinAlloy double skin kit for cockpit floor,radiator and rear bulkhead.180.00
AP Brakes12.7" vented disk kit with billet fixing kit.1625.00
Handbrake CalipersPair of separate handbrake callipers for above.275.00
Air Con kitAir conditioning kit including integral heater.1275.00

The lowered floor pan is to give me a bit more clearance for my bonce and for knees under the steering wheel. At 6'5" I think I'm approaching the upper limits on height for an Ultima. When I visited the factory I just fitted but it was a tight squeeze. On sitting in a car with the lower floor pan at Stoneleigh it was much better. In addition I might fit the seat without runners to gain a bit more room. In the Westy I've raised the steering column but that isn't possible in the Ultima.

I can't imagine many going without at least the roll bar, the full RAC cage seems fairly obligatory to me. The double skin kit isn't a great deal more expensive and in addition to improving the finish will hopefully add a bit of sound proofing. Not sure if it also improves radiator air flow.

The AP brakes are expensive but weren't something I spent long thinking about. I'm not building this primarily as a track car, but I expect it'll find its way onto a couple of circuits :-) The Evo has massive Brembos but even so one of the first modifications many owners make is slapping AP brakes on.

The air con kit represents a fair additional expense but again I decided on this quite early on. When I first saw the Ultima it struck me that the cockpit looked like it could get quite warm on a sunny day, especially with a tuned 6 litre V8 sitting just behind you. I know some of the guys building fairly track oriented cars have gone without, but I think it will be fairly useful on track too. My Evo has had an ECU transplant and I'm still waiting for an update which will allow the A/C to work. I did a trackday at Donington last year on a nice sunny warm day and it really was hot in the cabin wthout the A/C.

What engine am I putting in it? Not sure yet. I certainly don't plan to go for the 'standard' 350 cubic inch (5.7 litres) 350 bhp Small Block Chevy, and at the other end of the scale I don't want a complete firebreathing monster. My main concerns are the initial outlay - once you get above about 450 bhp the cost starts to rise exponentially and you need to think about dry sumping etc. - and durability. Fuel economy is also an issue, even in a low state of tune I suspect Ted's claim of 18 mpg is likely to be well on the optimistic side! Don't worry Ted, I don't hold it against you! I've never been a very economical driver, if there's power there I'll want to use it! I currently get 16 - 18 mpg out of the Evo, depending on how good a boy I am, and it can be a pain hunting down Optimax or Super Unleaded when you've got a 48 litre tank. The Evo generally does about 7 mpg on track, and I expect the Ultima to be no better, and even with twin tanks it won't have a colossal range. At the moment I think the likeliest option is one of American Speed's 383 ci (6.3 litres) 450 bhp engines. That should give me a power to weight ratio about double the Evo's, ant there aren't many cars on the road much quicker than that!
