The price (£) of power?

[chrisBoid]

I posted this in another thread but I think it deserves it\'s own to get a bit of focus.

I think it would be a good guideline if the people in the know could answer the following question: -

How much would it cost to take a standard 3rd RX-7 and have it produce x amount of rwhp in street trim (without Nitrous) AND still handle great, more of an all rounder than being better at one discipline (think TOTB).

300rwhp
400rwhp
500rwhp

What would need to be replaced/removed/altered?
Would it still be streetable at all these levels?
What could you expect on the 1/4 mile?

You meant like some of the EVO, Skylark etc tuners advertise?

E.g. 300bhp needs this and this, costs XXXX

Trouble is these things are never really that indictive of whats going to be needed, \'cos you never know what horrors are going to be found lurking in the engine room!  The best thst could be achieved is to say:-

 \'Parts A thro\' G are needed, plus work X on Model Type Y.  Prices start around XX but may end up being XXX when we discover the family of dead squirrels in your inlet manifold....\'

Can\'t comment on what the skybus and scoob tuners advertise - never take any notice!

Yeah, any figures will always be tentative of final costs, but a ball park figure is still a good starting point and a goal to aim for.

my 3rd gen type r has twin HKS induction and kakimoto backbox, so how much power should i epect from that? its a fairly cheep mod to do.

What if they already came and took my nutz while i was sleeping?

[Brett]

Well sadly you wont be covered for lost nutz, however if in the future you upgrade to nuts then an RAC NUTstar tracking device can be installed to ensure you get them back quickly.  
 As for your missing nutz, I expect they\'ve been resprayed and sold into a squirrel prostitiution ring.

It is kind of a difficult thing doing a breakdown like this (in hp brackets). I think it is better to look at it in the following way (a price breakdown of the bits):

1. Engine block with all new parts (possible dowelling - although there are some 800hp 13B\'s that don\'t have dowels!):  Â£3-5K
2. Porting: £500  (peripheral port maybe more)
3. Apex Seals: £200-600  (go Ianetti or standard Mazda - both work!, but there is a big difference in price).
4. Intake, 500+RWHP and you start having to go with custom plenums, throttle bodies etc.:  Â£3000
5. Fuel system (again, more hp - more £): £2000
6. Turbo & wastegate (you could run multiple also): £3000
7. Exhaust (inc. proper manifold): £2000
8. Intercooler/charge cooler (incl. plumbing) £2000
9. ECU!!! (again more £ - the better it is to tune): £3000 - based on the best gear
10: If you are planning on running 10\'s the standard FD gearbox with slicks will last a number of runs, but not a lot! Clutch, and Diff has to be taken into consideration, SO!: up to £10,000
11. Wiring (labour): £1000
12. Pluming and fittings: £1000

Tyres, tuning, blah blah blah!!!

Maybe £30,000-35,000 or so - should get you a consistent 9 second FD.

On the other hand, you could get into the 10\'s spending a hell of a lot less - by not getting all the good stuff, not using new gear etc.

[chrisBoid]

Excellent information

Personally, getting into the 10\'s would be my limit, my ballpark figure for that was £15-20k for a reliable upgrade package.

[g11ary]

Just be careful who you throw £35k at that might be the right amount of money, but after suppling the engine, ported and dowled, supplying the exhaust system, the turbos and giving £23k to a specialist, he still cant give me a 10 sec car.

[chrisBoid]

Agreed, serious vetting needs to be done.

I\'m not sure if the upgrade could be staged over time, as upgrading one component means another must be upgraded and so on.

Which means I\'ll have to save a lump sum, and with these estimates, that\'ll take a while.  Over that time I can increase my understanding of what needs to be done and the tuners will have increased their skills.

Gary, may I ask how your car is coming along now?

I don\'t have one as yet, but it keeps looking better every week.

My plan (albeit only in my head right now, as I don\'t have anything to play with) is roughly this.

Get the thing.
Give it a good clean, check everything with service manuals and wiring diagrams on hand. Make sure it\'s all there and accounted for. Find out what it\'s got as a baseline.
Rebuild the suspension with the best I can justify.
Brakes are open to speculation. I could do something strange and get a set of Harrop calipers/rotors at a good price. Whatever, they will be good.
Wheels of course to clear the brakes, plus some rubber to keep the rims from digging furrows in the road.
Clutch back driveline. Wonder if Mr. Holingers brother/nephew still remembers me?
Bodywork. Remove any superfluous weight. And I plan to do my own carbon. Done it before, just not on a car sized scale before. Should be fun and tie in with how my career seems to be heading right now. Make it light, strong and stiff.
Electrical. Reduce electrical consumption, re-wire the whole thing and wire in a proper ECU.
Last, but not least!
Engine. By this stage a little time will probably have passed. But the car will not have been driven a great deal. It will also be capable of using whatever amount of horsepower I manage to find most effectively.

Going this way, I should wind up with a car that is fast, and can handle it. I should also have brushed the cobwebs out of my system and wont make it go all pear shaped. I can also spread the cost out over a prolonged period, or a short time if finances allow, while still having something I can take for a fang that will constantly improve with time, like a good wine.

Driven more than a few cars with lots of power and nothing else. Not much fun to be blunt. Also driven a few cars with great grip, but little go. Quite entertaining, and embarrasing to other road users.

Anyway, maybe ambitious, maybe a long time coming. But at least I should be able to achieve it for reasonable cost, and I can bail out if required early on without dumping a bucket of cash if something comes up and I must direct cash to more important things.

That\'s me.

I also live in Japan, which helps!

I honestly believe that we have some great engine builders in this country and have 100% faith in what Carl Hayward does, unfortunately there is no one yet that can offer a complete package that can deliver a 10 sec car YET.
I personally have now looked at the costs of shipping a car out to OZ and having them tune her. For what Reworx have charged and the standard they have delivered it will be cheaper to have the car assembled and built to your spec here and get the experts to finish her off. Dont tell me about warrentees as I cant imagine anyone warrenteeing a 10 sec anyway and there was a post this week about a car built in NZ and has run for 4 seasons without a problem.

My car is off to Rotechniks this month as I waiting for David to get back from his hols and for them to free up some time and space, and waiting for DS Engineering to finish my hydrolics and roll cage. My car is available to look at until it goes to Rotechnics if anyone is interested in looking at UK workmanship.
Then the courts will decide.

Once a report has been finished I will post in the old thread I had going ( where to go from here) and will eventually post proceeding outcome.

Yours sincerely
Bitter & twisted from Dartford.

What Gary is saying is that the engine (Supplied by me for TOTB2 as a sponsorship for that event only and after be returned to me) turbo\'s and exhaust were all not the cost\'s incurred by the person assembling the package.It has kept me out of pocket to the tune of £5000.00 for the engine still sitting in Gary\'s car.(Not Gary\'s fault)
Those items were additional to the £23,000.00.

Now I do oversee the whole package on cars because of the major problems incurred by the events referred to by Gary.
It has been a long drawn out exercise with Gary\'s car,I should have had the engine back over 1 year ago now!But we are sticking with it until it runs some fairly quick times.

Shame really cos it would have been good for a few of us if the work had been successfully completed when it was supposed to be.Gary\'s car would in all likely hood have been where Geffs and Ross\'s are now but over a year ago.

Anyway both myself and Gary have been stung but it is a good job we are patient.
Our time will come.
Kind regards
Carl

[Carl]

If anyone wants a 10 second car then I can do it for £35,000.And actually much less!
Kind regards
Carl

[mattmaclennan]

I can do one for £34999.00

:rollin

here we go.....!!!:D
