Rizhto Posted April 7, 2005 Share Posted April 7, 2005 This is a simple question but internet has too much information and I don't have time to search. I need to know what are the biggest and most powerful in line six engines ever factory-assempled into the Herald/Vitesse. I've heard about 2,5 litres, but are those later modifications? The reason I'm asking this is the Finnish law. We are planing of building a turbo loaded in line six into a Herald but Finnish law allows non-stock engines to be only 20% bigger and more powerful than the biggest stock engine in the same frame.

Tim Bancroft Posted April 7, 2005 Share Posted April 7, 2005 The biggest engines installed into a Vitesse by Triumph was the 2.0 litre six cylinder engine.Good luck Link to comment Share on other sites More sharing options...
Rizhto Posted April 7, 2005 Author Share Posted April 7, 2005 So the 2,5 litre Vitesse racers are not factory-racers. Even one or two ever made would be enough. They don't need to be serially broduced as long as they are factory-made.This means that Toyota Supra engine is out of the question. Link to comment Share on other sites More sharing options...
Rizhto Posted April 7, 2005 Author Share Posted April 7, 2005 This is what interests me.http://www.bsedan.com/vitesses.htmIs this a factory product? Link to comment Share on other sites More sharing options...
Tim Bancroft Posted April 7, 2005 Share Posted April 7, 2005 I think this Vitesse was built by Kastner Brophy racing in the USA, therefore it is not strictly a factory built racer, however Kas Kastner did run Triumph's racing operation in the USA.

Paul Garvey Posted April 8, 2005 Share Posted April 8, 2005 Yep I'd expect a Supra would definately be out. What about a smaller capacity motor and bolting on a small Toyota 4AGEZE supercharger?. Has the bonus of a manually operated electric clutch so could 'disengage' for the 20% threshold test...I've been tempted to pop one of these cheap beasts on the Vitesse...

Paul Garvey Posted April 8, 2005 Share Posted April 8, 2005 Smaller moter as in a 1600 or 2 litre Vitesse. Link to comment Share on other sites More sharing options...
Rizhto Posted April 8, 2005 Author Share Posted April 8, 2005 The point is that the combination will not be tested. The only thing MOT inspectors are interested is the original factory data sheet from the frame manufacturer and the engine fanufacturer. They look at the official numbers (hp,cc and weight) and calculate. Nobody is interested how much power the engine actually gives out. After the MOT only heaven is the limit in tuning (and a bank account). I was going to assemble a Range Rover v8 but the regulations were tightened few years ago, and now I'm have to make new plans. Therefore I'm looking for suitable in line six twin cam (preferably 4 valve), which fits into new regulations. Of course I could buy a Alfa or Fiat TC 4 cylinder or a Ford v6, but I want it to be in line six with twin turbo. Link to comment Share on other sites More sharing options...
Rizhto Posted August 16, 2005 Author Share Posted August 16, 2005 Well, here is the sketch of my Herald project. they say that well planned is half done, so I "only" need to finish the other part ;). The idea is to convert the Herald saloon into a two-seater cabriolet by moving the firewall backwards some 20 sentimeters. This also gives more space to larger engine. Bottoms of the doors will be lifted to make space for tube sub frame. I will not tolerate any flexing. Originally engine was supposed to be that Rover v8 I mentioned, but now even the option number 2, the turbo-loaded in line six, is out of the question. Turbo attachment is considered as an engineswap and numbers would be re-calculated. Do you have any ideas for new engine? My head is empty. I want it to be an in-line-six and its maximum output can be 124,8 bhp and max. volume 2397,6cc. I also want the engine to be fairly light and that spear parts are availlable and reasonably priced. all other comments are welcome as well.

James Posted August 16, 2005 Share Posted August 16, 2005 I don't think you're going to find anything better than an overbored 2.2 litre Triumph unit?!How about moving it back (as the bulkhead is going back) - it will transform the balance of the car...

rotten herald Posted August 16, 2005 Share Posted August 16, 2005 i have seen a 3.8 jag engine in a vitesse, admitatly with modified baulkhead but didnt seem too pushed for space, did once consder the supra unit, but is a little to tall,i would suggest u look at nissan 6s, you can have anything from th 2.4 laurel/z engine up to the R33 syline lump, and the fit, as i trail fitted one from my 260z even the gearbox is relativly compact Link to comment Share on other sites More sharing options...
Rizhto Posted August 16, 2005 Author Share Posted August 16, 2005 yep, I'm going to move the engine back. I have two frames (actually four), which i'm going to connect so that engine will move back as much as the bulkhead. The only problem with triumph 2,2 is that it's bloody rare here in Finland. Herald is the only Triumph ever sold in reasonable numbers. Supra engines, even the smaller one, are too large and too powerful. Nissan twincam sixes (Skyline) are also been looked trough. the mildest one has anoyingly 130bhp, 5,2 too many. This engine is also more of a short stroke revver and I'm more into torque motors. but this Laurel 2,4 sound really interesting. Laurel is a common car in local junkyards, although they are mostly 2,8 diesels. Got to look trough... Link to comment Share on other sites More sharing options...
Rizhto Posted August 16, 2005 Author Share Posted August 16, 2005 Argh! couldn't fin any clear information about the Nissan L24 engines. looks like those under 124 bhp versions are from late 60's and early 70's. The Laurels and Cedrics I know are from the 80's. It might be possible to find a L20A engine, which is only 1998cc but better than nothing. 1984 Skyline is been made with 124 bhp L24E engine, but that might be hard to find.

Rizhto Posted August 17, 2005 Author Share Posted August 17, 2005 do you have any stats fo the BMW? horsepowers, when produced, which models assembled? Link to comment Share on other sites More sharing options...
Rizhto Posted August 17, 2005 Author Share Posted August 17, 2005 M60 and M20B20 are worth looking for. Engine is tilted, which I don't prefer, but it fits into the limits. Link to comment Share on other sites More sharing options...
Smallfry Posted August 18, 2005 Share Posted August 18, 2005 Sorry I dont know anything about BMW apart from that they are overpriced and overrated !I was just trying to think of six cylinder four valve engines that would be easy to obtain.The old Nissan engines are only two valve .

DaveKent Posted August 18, 2005 Share Posted August 18, 2005 bmw six cylinder engines are superb. they are silky smooth with loads of revvy power. theey are fantastically engineered and yet very simple. parts are easily obtainable and unlike many performance engines, parts are reasonably priced from many specialists!!

Rizhto Posted August 18, 2005 Author Share Posted August 18, 2005 I have to forget the four valves. They seem to be too powerful in general. two valves must do. I looked trough the BMW stats and noticed that the engine has to be from 1984 or older. In 1985 the performance of the BMW six rises from 124bhp to 129bhp. These old BMW units are not four valve motors, I guess. The good thing is that those late 70's-early 80's 320 and 520 BMWs are common and really cheap. The fuel injection version looks better than the carburetor version, but it has 125bhp, which is 0,2hp too much! I'm not sure if it's accepted.So now there is two options, Nissan or BMW. Anything else in mind? Link to comment Share on other sites More sharing options...

Rizhto Posted August 18, 2005 Author Share Posted August 18, 2005 This leads to intersting subject. Are there any laws and regulations for building a car in UK? I lived in Sheffield for 5 months couple of years ago and me and my wife did liked the country. Of course there is some things, which can never beat the home country. At the moment we're pretty bound to this town, job, house, yard and some 70 squaremeters carage. Couple of years ago we were planing of moving to the UK but not anymore.

Snowbunny Posted August 18, 2005 Share Posted August 18, 2005 How about this powerplantDisplacement 2294.00 ccm (139.98 cubic inches) Power: 142.00 HP (103.6 kW)) @ 5750 RPM Torque: 200.00 Nm (20.4 kgf-m or 147.5 ft.lbs) @ 2500 RPM Compression: 8.7:1 Bore x stroke: 101.6 x 94.3 mm (4.0 x 3.7 inches) Fuel system: Injection. Multipoint sequential electronic fuel injection Fuel control: DOHC Ignition: Digital - inductive type - via electronic engine management system Starter: Electric Cooling system: Liquid Gearbox: 5-speed Transmission typefinal drive: Shaft drive (cardan) Clutch: Wet, multi-plate An added bonus is that it is a genuine Triumph engine, the pistons are a similar size to those in a Dodge Viper, although you may find that it's only half the number of cylinders you were looking for.

Rizhto Posted August 23, 2005 Author Share Posted August 23, 2005 hih.. funny.I think I go for BMW rather than Nissan. Engine is more developed and easier to find. Also I believe I can squeeze more power out of it without giving away too much confortability and economy. The biggest problem might be the front sump. I have to move the front transverse beam to some direction in the frame. Thanks for all the help and if you still have some ideas, I'm listening.

DaveKent Posted August 23, 2005 Share Posted August 23, 2005 instead of altering the chassis, why not find or make a sump with the well at the back?! Link to comment Share on other sites More sharing options...
