Right, i'm trying to decide what engine I will be putting in my indy, and am after a few suggestions.

I've not got a great deal of mmoney to throw at it, but want to get the best possible power output.
The r1 engine looks good at 150 ish bhp
Busa is out of my price range, and I don't want the extra expensive of dry sumping.
Can you just drop the zx12r lump in with existing ecu? or will I need an aftermarket piece?

Has anyone gone the big v-twin route ala vtr100 etc?

How come no-one seems to use gixxer lumps? the are cheap and plentyful.

Cheers
Ben

r1 is the baby!

Bang for bucks = R1!
Carb'd 'Blades can be picked up a bit cheaper but not that much...

GSX-R's need to be dry-sumped, so if you're on a budget they're not an option.

A few people have used v-twins (I nearly went for an Aprilia) but the 4's seem to be more popular. I haven't tried a twin in a car but would like to.....

You'd really need a Power Commander on a ZX12 to fuel it properly, but as engine prices are dropping and it seems you can get away with a wet sump, there's a good chance that these'll take over from the R1......

Value for money I would consider CBR1000 or Fazer 1000 as well.

R1 engines only need a sump baffle to work in a BEC, as do blade engines. Many others need dry sump systems that cost more than the engine.

Blades tend to be cheaper than R1s by a small amount but have a small amount less power. I picked up an R1 and all the kit of eBay for £600 ish and is a bargain.

If you use the engine as is, including the air box and exhaust then you won't need to change anything. Airboxes are hard to fit under the bonnet of a car and straight through exhausts are popular. You may find that you need a carb jet kit or a power commander for fuel injection to sort out the fueling to cope with the changes. £100 odd each.

Carbed R1s can go up from 148 BHP to 155 or 160 with a jet kit fitted. Early FI engines may be the same.

2004 an on R1 FI engines make 180 BHP but only by adding another 2000 RPM onto the top of the rev range. Their closer ratio gearboxes make them less suitable for a BEC in my opinion. You probably won't end up with a car that is any quicker on the road.

The bigger 1200cc+ engines are going to be more torquey and are undoubtedly better but they are expensive. I settled for an R1 beacuse of this. I liked the idea of an RSV Mille V twin but the R1 was just easier as everyone has jigs for mounting cradles and exhausts.

Carb'd R1, a bit easier than fuel injected and doesn't need a power commander.

Thanks for the replies chaps
looks like the weapon of choice is the R1 for me then, i'll get hunting.

Speak to Yorkshire Engines and Colibriman - both are top chaps!

Have a search for Yorkshire Engines, his name is Malc, he'll deliver one to you.

If you need a hand with the install I am only down the road in Horsham.

Most appreciated Jim
Noticed there are a few builders around this area, seen a few kits round horsham too.
Do a fair amount of work at the swan walk shopping center so over there alot at the mo.

I’m putting an aprilia v in mine, it’s a 60° v and only just fits with good prop alignment! Recon a Duke, TL or VTR engine would be almost impossible to fit (may be wrong). Should be ready in a couple of months so shall let you all know how it goes! Dry sumped as standard and a cheap engine so can’t grumble!

There,s a lot of talk about gsxr k series engines needing dry sumps and i cant understand why iv sold over 40 engine kits to racers kit car builders sidecar drivers grasstrack drivers and
iv raced gixxer 1000 motors for 5 years now and never ever blown a motor
im so convinced my wet sump system works gsxr motors are reliable powerfull engines
my tuned one makes 192 bhp at the crank and ran for a full season last year before being stripped for inspection
i replaced the bearings as a matter of course only because it was being sold to another racer
try them out if im wrong ill drink my sump oil

Mal, is that with the engine east/west in a rear engined car though? I think a lot of the problems (its certainly the case with other sensitive engines like the Blackbird etc) comes when put in a front engined car with a north / south configuration.

As Chris has said Malc, they're fine when in normal orientation (i.e. in sidecars, grassers etc.) but when turned through 90deg. they spit their dummy out!

None of the RGB boys have had a wet-sump motor survive apparently, though Nicky Kennedy said that he could make a baffle that would work for the motor I originally got from you but I wasn't convinced and didn't want to find out the hard way......

Hi

I have a triple in mine !!!

I'm not saying its the best engine but god it sounds good

and I picked up a 03 daytona for £500 as a spare

but I'm running chain diff so not sure how good it is if turned through 90

I just thought I'd add another motor to the mix

The problem with the V's

is defenitly the output position.

They are further away due the fact that the head is leaning forwards.

anyway every engine has his pro's en contra's...

I never would buy a busa or ZX12R just because it costs allot of money and you will need also the money for the fuel to feed it.... else their are 0 BHP!

in my case i wanted to do something
- new (V4)
- allot of revs (bike engine)
- no much fuel consumption (being able to do big travels)
- light engine (less tax / better cornering)
- small displacement (less tax)

Regards & goodluck witht he build
