IPRA Car building
Just a quick one re cars elligibility.
I understand you can run a motor as long as its from the same manufacturer.
Would a Daihatsu chassis be able to run a toyota engine, in the same way a lexus, or mazda / eunos, Nissan/ datsun set up? After all Toyota has had daihatsu for 10 years +
Also I am interested to know what 'package' one needs to run to be competitive in 0 -1600cc. In terms of basic Hp, brakes std or c/r boxes etc. Please disregard inputs from behind the steering wheel.
I am at the planning stage and am looking fwd to some pointers
The benchmark 1600 cc cars are the Suzuki GTi 1300cc Grant Wilson ran in NSW last year, Sam Maio (sp?) in a 1600cc Suzi (NSW) and the Mirage Cup cars run in all states.
About 200 Bhp per ton seems to be the go for the front runners, and CR gearbox is desireable because, this power comes up high and you don't have heaps of torque. So you don't want to come off the cam.
LSD, locked diff does pretty much as well

It is not about ownership, this is about badge engineering. Otherwise I would like to put a E30 M3 motor in my mini thanks very much!
The 1.3 and 1.5 Echo motors will be ok, as they were in the Sirion
Personally I always thought a 3 Cyl Turbo with mega boost would be interesting. 230 hp... hmmm
It is basically standard except for an exhaust upgrade, brake pads and intake (Uni Filter). I have not dynoed the car so don't have HP figures. Standard figures for the B16A engine fitted to it by the factory is 170 HP.
My best lap time at WP was a 1:15 in qualifying but I'll qualify that by saying that before that day I had not even driven the car, having spent 4 months building it after it landed here in early November.
I plan on some performance upgrades over time (as budget permits) and am eventually aiming for somewhere the other side of 200HP.
The thing you have to remember is that HP costs $$$. Unlimited dollars can yield maximum HP. Do you want to race reliably or rebuild your engine after every other race meeting?
My aim is to enjoy my racing on a sensible budget.

Ask rj41 what set up he runs in his Corolla. He's under 1600 but won the NSW under 2 litre champs last year...

Re: IPRA Car building
Firstly Welcome Global!!
Good choice of Category!!
For what Its worth, and not knowing Diahatsus, the following engines are in eligeabnle cars as they are Gp A Homologated,
Charmant A45 (1588 cc)
Charade G 10 (993 cc)
Charade G11 & Turbo G11 both (993 CC)
Charade 3 Door G 100S (993 cc)
Charade GT-G 100S (994 cc)
Charade 1.3 i G102S (1296 cc)
Charade G10 (993 cc)
If none of these are acceptable, I recon your on a good track, however the etc in the CAMS manual may need clarification prior to you spending your time & energy getting it together. It may be worth dropping your State Club Pres a line asking for clarification from CAMS. Have to be a good chance that it'd be OK though!
Arent They dropping the Diahatsu name here now?

Re: IPRA Car building
If I understand the rules correctly is the following acceptable:
If I run a 1994 car (modern?) I use the orginal engine (1500 or 1600cc) I can run the car as light as I can build it?
If I run the car with a replacement engine ( from the manufacturer in this case assume toyota 20v 4AGE or alternative toyota / daihatsu engine) I need to run 965 kgs?
Does this make sense?
The reason I ask is I have a current car, which is roughly 900 plus kgs with 160 bhp. The engine will not deliver a great deal more as its only single cam, with cranks and conrods made of cheese. I was looking at either lighting the car, or uping the power.
It is theoritically possible to get 200 bhp and around 800kgs with a std engine and some $$$$. But reality and theory are different ends of the budget spectrum.
Turbo's are a worth while option on the 993cc, giving 200 plus hp. But as this makes it 1600 - 2000cc class and heavier and less competivie than perhaps a

Re: IPRA Car building
Ok I am getting an better understanding.
A modern car > 1986 needs to run the orignal engine (or family of engine) and run a min weight of 965 kgs?
Quote:A modern car > 1986 needs to run the orignal engine (or family of engine) and run a min weight of 965 kgs?
Not AND, but OR
Keep the original motor (and head) and there is no limit
Please also remember that these are Race weights, wich is a defined terms, and includes the Driver, fuel and everything at any point of time, typically measured at the end of the race, kitted up I come in at 110kg, plus some fuel, means 845 kg for the car, which is pretty light.

Re: IPRA Car building
over 200hp out of 1600cc means you have to rev over 9000rpm , thus the min you need forged pistons & rods , 4 t/b , computer , min cost $6000 + , without good handling & close ratio box , this is just a waste

Doesn't seem like much of a waste to me rx3ip
I'm pretty happy with my u1600
Global, personally id be looking at a Mirage if you didn't want to go down the path of building a car from scratch, they really are good piece of gear and you can get them for very reasonable money.
The idea of building a Daihatsu is great, but you will spend a considerable amount more building any car from scratch as apposed to purchasing something that is a good package up-front

Or the Grant Wilson Suzuki (if it is still available)
Few hp down on a Mirage, but also 150 kg lighter and always faster, and about $4k chaeper when it was advertised. ($10k vs $14 ish)

Re: IPRA Car building
Yep, just completed a successful trip to the dyno. Planning on giving it a bit of a shakedown at EC the Friday before Round 2.
Not entered in the meeting though, need to get some seat time in it first.
Looking at entering it in the ARDC Multiclub meeting next month with any luck.

Re: IPRA Car building
I have built one before and have the still have engine, ECU, C/R box, LSD, Brakes, and coil overs. Its not in a package that would easily fit the rules of IPRA.
So I am only short of the cheaper bits - A new cage and shell and the preparation to make the above basic car into a race prep car. So its not like a project from scratch. Event with all the bits above you woud not get alot of change out of $5k on top to prepare a new shell.
I was just trying to ensure for the effort we will get a car that does not run last by 5 minutes a lap.
I think we will run the existing car on a few track days to see what basic times we can produce. To see if the package can compete or how much developement is needed.
If anyone has an old set of 'cheapish' tyres we could get hold of that would be great. - 195/55/14, 185/55/14, 185/55/15 or similar let me know. They are only going to be used for track days / testing work.
Re: IPRA Car building
Don't underestimate the cost of a cage, especially if you want a few extras
Those tyres are all odd sizes for A032/A048, so you may have trouble securing Yokies (I woudl suggest impossible second hand), there is a thread with the sizes available, check that out. (There is a US site as well, but some of our sizes are different)
As a guide, most of us run tyres to the canvass!
The most Popular sizes are
205/60/13
195/6014
205/60/15
225/60/15
I think the Mirage is on 205/50/15, but it may be 195/55/15, this would be your best bet.
