Cheers mate pry anything you can out of him im all ears.
Cheers mate pry anything you can out of him im all ears.
awesome work
also interested in the motor
ive just finished rebuilding my sr16ve , forged rods , n1 pistons , n1, cams etc and sr20ve crank, if anything were looking at putting out over 140kw atw before upgrading the cams again.
what head issues do they have? i was under the impression that the sr20de motors had rocker issues if revving over 7.5k , yet to hear anything about the sr/ve motors
Have to admit my thoughts on the supertourer engine are changing. I was expecting double the cost and more restrictions on parts that could be used in the build.
The only problems that ive heard about is the variable cam timing playing up a bit. 140atwKW is awesome, 240fwHP that's a decent engine out of a 2 litreOriginally Posted by obsessive

Dont forget supertourers came from the era of unlimited budgets.
I recall hearing a rumour that Audi was spending as much on it's supertourer program that some of the F1 teams were. And the rest weren't far behind.
Was it Nissan that swapped the intake and exhaust around so the intake was on the front of the engine?
Some of the later engines had the injection on the opposite side. In 1999 when nissan won the championship they spent 50 million dollars for the year
ahh double post again.

Got on to my mate. He worked at an engine shop in the UK that had all the primira (?) super tourer bits in a Micra rallycross car. He wasnt that sure of the head on it? He did say there was 3 different ones and the works cars made 294hp. Apparently they were limited to 8500rpm as a 8600 they popped rockers every time. He hasnt seen any better than 260ish out of an SR out here and reckons unless you've got a uk contact thats all your going to get out of ported standard stuff. His opinion was the SR wasnt the way to go if your looking for 300hp. Your better off de-stroking a KA24 or a Q series engine? (x trail or something?) heads flow heaps better. He does have some pics of the Mirca somewhere and hopefully he'll pass them on and post them up
Looking for 86 GSXR bits. PM me
sounds like a challenge for TK, If any one can do it it has to be TK thou it will take a lot of time unless folding is not a issue
I have CDO. It's like OCD except the letters are in alphabetical order, as they should be
i have sexdaily, i mean dyslexia
If i was really serious i would use either.
-s2000 engine
-SR20 de-stroked to 1.1L then turbo
-Mazda mx5 bp18 de-stroked to 1.1L then turbo
-Hybusa de-stroked to 1.1L then turbo
Those 3 turbo engines will make around the 400+hp make making an N/A engine worthless.
I thought it had to be a car block?
Swift motor + turbo?
"Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."
Yeh something like that, theirs a Suzuki cappuccino with a Hybusa being built at the moment but it must have a swift block.
not doubting you on the fact that is has to be a car block, but it seems a bit stupid to rule out bike engines. It is not as if they are really that much more difficult to find and provide any real advantage.
Is the rule to stop people using weird things like aircraft engines or purpose built racing engines like a Judd V8 or something?
Are after market replacement blocks allowed? i.e. a Rodeck SBC (or even an after market iron block if alloy wasn't originally used)?
That's where it gets a bit grey - they allow the aftermarket blocks, but the intention of the rule is stopping the Judds/Cosworths/etc...

after you build it how much ballast would you have to run fitting a massive V8 in it?
I also have to say fantastic build, how come the botton half of the chassis is blue?
They want production car blocks or after market blocks of the same design. For example a ford motor sport Windsor block is fine.
And now i think the engine has to come off a production line and doesnt have to be out of a car.
As for the ballast with the v8, i hope it needs some but its very hard to also reach the 1125kg mark with a v8. But my calculations say it will weigh 1140kg with a dodge nascar engine.
The blue steal is just paint and the cage hasn't been touched yet. Ill have to spray something on it soon its getting a slight rust tinge to it.
I considered building a rotary powered round nosed mini with a VW transaxle, but I may as well finsih this one off and make that my next project. I looked into doing something like this with a mini and got a rude shock how much ballast I needed to be elegable
Sounds like the early Nissan effort....probably from when Jan O'dor's(sp) son was killed, later engines were barrel throttles.
A mate has a set of the mid period Mallock(?) cams I'm sure he'd be willing to dispose of...I know the last UK engine developer for Nissan told him the finger followers were more than he could afford!According to the third hand I've been fed, anything but the GTiR heads were rubbish from a power perspective....and I suspect that applies to any of the all-singing later heads too with emissions getting ever stricter.
Final developers of the supertourer engines prepped the Sunny engines.
yeah that is kind of what I figured.
Does anyone know if they let you run an Aluminium replacement block if the original was cast iron? How would they feel about things like raised cam blocks, where many parts wouldn't be interchangeable, but it is still considered the same kind of engine?
No wonder the Sports Sedans are fairly V8 dominated, you could basically buy a nice, ready to run crate engine from the USA. I guess that despite the knuckle dragging mentality the yanks are stereotyped with, they still have huge amounts more people racing in equivalent classes to sports sedans.
It obviously makes sense to use an engine that has huge amounts of aftermarket support and has been a proven package in that environment.
The reason the v8's are so competitive is that no one has built a strong turbo engine. The best attempt so far was bobby irving who had a sr20 with a stock bottom end and wasnt far off the front runners until it got hot.
The front running cars are making 750hp and limited to 7800rpm in a 6 litre engine.
Weights are with driver. With a cams cage its hard to achieve.I looked into doing something like this with a mini and got a rude shock how much ballast I needed to be elegable
The block has to bade from the original material the production block was made from. Bugger alloy chev would be nice.Does anyone know if they let you run an Aluminium replacement block if the original was cast iron?

I suspected that, the GTiR heads are more bulky through the rocker gear as well, and the head doesn't fit on a non gtir block, from what ive been told.anything but the GTiR heads were rubbish from a power perspective....and I suspect that applies to any of the all-singing later heads too with emissions getting ever stricter.
Just got a quote to build a chassis.
starting from 20k and you supply the materials.
That's 20K of labor, shows the amount of work that goes into these things.
Beninca's were reasonably sucessfull back in the day with their Turbo GTV weren't they?

I name rings a bell just cant put a car to it.
There will be a killer batch of nissan 3 litre v6 turbo engines coming out soon.
1050kg min weight. 700 race hp, and 1000 with the fun button. But how long will the rules let these monsters go for. The v8 blokes always pull their authority.

Ahhh, the memories.

Keith Carling ran the yellow 300zx years ago with the datto V6TT, thats the car that prompted the rule change (which has now changed back). I believe it still holds the top speed record down conrod at 340 or so kph.
I know where you can get an ex Newman Haas Mechacrome nissan V6 that was good for 1500 odd hp in the Paul Newman cars in the US...you will need considerable funds though....like more than what you would need for a 6 litre nissan V8 all built & done.
Theres a bloke in adelaide who is building 3 litre nissan v6 twin turbo. ex gt2 stuff, cant remember the exact class. Reasonably priced.
Do you know what engine was in that car, vg30? twin cam? ect.Newman Haas Mechacrome nissan V6 that was good for 1500 odd hp
That is the engine...it looks just like a VG30 on the outside...but its all much gooderer on the inside. Its basically a big dollar cheater donk, the class required a production block to be used but they split in two...so they made these ones.
One of them is being used here in some hydrofoil racing boat...no clue on class but they go round & round bouys on lakes mostly

these are the engines my mate in sa is selling.
Who made the new blocks? Nissan? Mecachrome?That is the engine...it looks just like a VG30 on the outside...but its all much gooderer on the inside. Its basically a big dollar cheater donk, the class required a production block to be used but they split in two...so they made these ones.
