7 type of car, but what engine ?
Discussion
In April I´ll be looking for a nice new impracticle car, and if the chips are in I'll be looking at an SR3, if not...well Im after a 7 type of car but not sure which engine to go for.
I really am keen on having a powerful bike engine like 1300 or 1500 hayabusa engine, keeping the car light as possible, and revving to kingdom come !
Anyway, just curious as to what other people think is a good option.

I would love a V8 BUT I think I really want a sequential box hehe, and I prefer engines that scream, dont get me wrong if I cant find a good 7 type of car I'm also looking at chims 
So which of those two bike engines are better then ?
Im a total noob to all of this, so feel free to dumb your answers down at the moment.

Did the original 7 have an A35 A series engine ? Perhaps a little antiquated.
I'm a great fan of the 1.8E GM oHC 8V as found in astra GTE mk1's (and my early mk2 cavalier SRi. They only put out 115 BHP, but often they are free !!!
What about an XE on Throttle bodies or a VERY tuned LET from a Calibra Turbo (about 350 BHP possible for a reasonable cost- a mate has one with 375 Bhp in a cavalier Turbo but the previous owner had to spend £££££££££'s to get it.

You will find a choice of 5 ZX12 engines here.....

Malc is a top bloke, will happily supply a busa if thats what you want but the ZX12 gives just as much power if not a little more for 1/2 the price.
his engines are guaranteed too.
too answer your question nothing wrong with the R1 gives great power and proven in a BEC but so is the ZX12 and gives more power, the busa is also great in a BEC but costs a fair few more beer tokens.
And your right, nothing like a sequential shift and a 11k+ rev limit.

Ive had a few bec westys to include blade/zx12/ and 4 busas including my current car of 2 years.. no question about it the busa is the quickest, zx12 comes very close and to drive actually feel quicker as they are very revvy but lack torque.. zx12 and busa do need dry sumping if on sticky tyres and used hard in a seven , normal driving they should be ok just dont brake hard ! .. powerwise R1 and Blade struggle in comparison in a straight line drag unless you can get the weight right down , end of the day its about power to weight .on a tight and twisty track the difference between them isnt as noticable..
Jon Ison said:
...plenty of busas and 12's out there without dry sumps including factory Radicals.
Do remember that the engine in a Radical is mounted at 90 degrees to the installation in a Bike Engined Seven, so sump surge is in a different direction.
Given the cost of a Busa engine, I wouldn't risk running one without a dry sump or accusump system, if it's going to be used for track work.
Dry sumps......
Been around BECS for years both on road off road and on circuit apart from the Bird I don't know of another engine that throws its internals out the side on a regular basis, I can understand the argument for one on a Busa too protect the investment maybe but then it would have too be on slicks before it could not be controlled with sump baffles.
All IMHO but personally, Bird aside I would happily run a bike engine without a dry sump system unless it was there for engine mounting reasons in a race car. As an aside I have lost 1 engine over the years on track, that was dry sumped.
Anyway merry Xmas all, do you work for pace by any chance ?

without a dry sump very hard braking on a busa will put the oil light on even with baffled sump :-(
as an aside the dry sump systems on a busa are not so reliable either though , belts can fail, Ive seen pumps sieze up, seals go on them all causing damage withing seconds and the level in the tank has to be checked on a regular basis ..
maybe another thumbs up for the budget R1 after all :-)

or a few sump mods not unlike the ones quoted below..
in our grp n saloon cars we where not alowed to run a dry sump system, and we had huge problem with oil starvation, we where however allowed to modify the sump, in this case we fitted a box around the pickup pipe with some one way flaps ( similar to those used in fuel cells these allowed the oil into the pickup area but not out ) never blew another engine ,

If I was going to go for a Busa, I would very seriously look at the american "swinging oil pick up" system, sorry, cant remember the name, but basically, the oil pick up is pivotted and free swinging, thus always in the oil.
Agreed that dry sumps also can create more problems than they solve, but I dont see any Busa's running in RGB in 7alikes that arent 'sumped.
If/When my 9r lets go, I'll def go for an injected R1 as I believe its the overall best solution for my use, ie track days and light road use.
The 12r isnt a bad motor and if I wanted the extra power would go that route rather than the Busa.
But..... with a bit of head work and some cams, my 9R wouldnt be to far off 165ish, and if it did throw a rod (usual method of engine destruction in a bec the new cams and valves would hopefully all survive intact.

I've had a crossflow westy, a v8 westy and am building an r1 locost. I'd say you'd be pushed to put any engine in a seven within reason and be able to call it bad.
If I was going for a car engine on a budget I'd go for the vx 2.0 16v engine and cobble some throttle bodies and use megasquirt. I guess zetec would be an alternative. For loads more money you could go for a duratec which have a very good reputation. V8s are superb but expensive for decent power and you need to choose your gearbox carefully as my R380 was very clunky. I did a track day solely in 2nd and 3rd because of the gearbox. The immense power made it ok but the gearbox took the edge off the fun. A T5 would sort that I imagine.
I'm going for a 2003 FI R1 engine because they knock out a load of power for a very good price. I have a sump plate to fit in it as used on sidecar outfits so it should be good. For me the price of the busa was prohibitive and having had a kawasaki bike which was unreliable from new I don't trust kwak build quality any where near as much as honda and yamaha. Fireblade engines are really good (have one in a fireblade with 30k on it) but they make less power year for year until recently so will cost you more.
