Nsr tuning

dude wheres my car · Guest

I am looking to spend a bit of money getin my nsr to have the same bhp as a pgo comet or a subaru imprezza twin turbo any ideas as i need some advice!!!

? · Guest

Buy a GSXR1000? You aint going to get a NSR to make the same power a an imprezza.

G · Guest

I'm not sure what the bhp/kg of a imprezza is but the power to weight ratio of a fully derestricted & tuned NSR probably comes close {until you add a lardy rider like me}
\lf;yeh, I know he's takin the piss\lf;\lf;\lf;[ This message was edited by: G on: 1-17-2002 14:05 ]

yeah maybe but as soon as that imprezza hits high revs and the turbo charger lights up...........bye bye nsr

I reckon a really well tuned (say 35hp-40hp, 180cc??, lowered weight) NSr could probably keep ahead 'till about 70-80mph. The only car that ever beat my slightly derestricted (about 15hp or a *little* more I think) NSR in acceleration was a BMW M3... and then it wasn't by much.
I have yet to be out accelerated below 85mph on my KLR650 (around 40hp but heavy at 165kg dry) despite a few sporty-ish cars trying.

NSR beating a scooby to 80!?! Don't think so matey. At about 218 bhp (270ish import!) and 4WD.....No chance. We may get a head start but unless youre on a bigger bike you aint gonna beat it to 80 full stop.Sorry to piss on your bonfire and all that but a half decent driver would prove this.Oh, best stick a drag spec gixer1100 engine in the frame if you wanna match it bhp to bhp!

By the way...That was a good guess G! A subaru impreza makes a bhp/ton figure of 219, whilst a relative figure (if an nsr weighed a ton!) for the NSR125 is 200 exactly, so the power to weight ratios,without rider/driver are very close. But with rider added, the difference is bigger in the scoobys favour.
God I must be fuckin bored. Sad

G · Guest

Being very bored at the time I posted, I actually looked on the Subaru site, but they only had the power not the weight: I thought they weighed a fair bit more than a ton, but obviously not.
\lf;Assuming a 40hp NSR with rider weighed 200kg that'd give you 200hp/ton... I reckon you could get the weight down a fair bit more though (a 150hp NS500 weighs 110kg, though they are a *little* more expensive).
\lf;
\lf;A while ago Bike (or some other magazine) did a test with a R1 versus an imported high spec Imprezza (I think). They did the test on some abandond airfield and set up some cones to simulate a road. If I remember the car won, but it did knock over a significant number of the cones and failed to stop in time at the end: in a real world situation it would probably have been mangled by the finish.
I think the bike won the other tests, apart maybe from the braking; though they did have an ammusing picture as the bike did a stoppie trying to avoid the car which was sliding out of control.
\lf;Yeah Im very bored now too

Actually if you've got £40k (only £10k more than the car) lying around you could just get yourself a second hand NS500 and paint '125' on the side. Assuming a 60kg rider that'd give you about 870 hp/ton!

Hi
From an issue of Autocar, the Imprezza weighs 1235kg and puts out 215bhp, which us 174bhp/ton.
Big advantage the Scooby has is better aerodynamics (which start to have a real effect from as low as 50mph) and the ability to just rev the engine hard and dump the clutch.
Some people I know built a 1 off car using Imprezza mechanicals in a glass fibre monocoque shell (no steel chassis). This weighed very little (at least 25% less than a stock Imprezza). Using professional timing gear they managed to get this to do 0-60 in 4.3 seconds, and that was with a stock engine but with a K&N air filter (no room for the original airbox) but not chipped. Biggest problem they had with that car was finding a suitable wreck to start with. It seems that they normally either just have minor traffic bumps and are repaired, or go off the road at such a high speed that there is not much left to salvage.
All the best

Keith...
Was this fibreglass subaru, the 'delfino'?
Coz it sounds like a very similar project.
(www.delfino.co.uk)

Keith · Guest

Hi
Yes, that is the car they built. They did a one off which as a prototype for someone who wants to put it into production. Given what he now claims for 0-60 I suspect he has now chipped it.
Just for interest, the front headlights are from an Alfa GTV / Spider on which they normally poke through holes in the bonnet.
All the best

I know this car well...
Because the fibreglass body shell that they are using for the Delfino, originally started out as a kit-car called the Minari. Which was designed to take an Alfa33 engine. (<A HREF="https://www.minari-register.cwc.net/Gallery.htm">https://www.minari-register.cwc.net/Gallery.htm</A>)
The designers of the Minari stopped making the fibreglass shells about two years ago, in order to develop the Delfino.
At the time i owned a Minari, so when i found out that the company was 'changing direction', i sold the minari , and hence bought my NSR!

a standard scooby turbo puts out 208 accordin to subaru, but forget bhp/ton for a min. a scooby standard does 0-60 in about 5.9, and its easy to keep it under 6.5, you would need a miracle start to get to 60 in under 7 on an nsr. acceleration on a scooby continues to about 110 pretty much without slowing, doing the ton in 3rd gear, u have no chance unless the driver fucks up, and god bless you when u hit a corner!

G · Guest

yea, I realise this wasn't a serious request
\lf;me disagrees.
\lf;
\lf;
\lf;We are talking about a *tuned* NSR, so I think a 180cc 40hp engine isn't too unreasonable. Add a lightened frame etc and I reckon you could cut about 20kg off fairly easily.
\lf;I reckon a bike with that spec shouldn't have too much trouble doing sub 6 sec 0-60. As I said earlier I still reckon a well tuned NSR could just about keep ahead to 80

someday I will remember to that html tick box Smile

yeah a tuned nsr prob will have a standard scooby up to 70 or so, only problem is your gonna blow the shit out of it if u race a few!
above was a super idea, get anything from a rs250/nsr 250 up and youll drill most any car on acceleration

ctyson · Guest

hmmm maybe but i still find it very hard to beleive.
evan a standard scooby packs a hell of a lot of power

Chris · Guest

I dunno.

A tuned 180 NSR would probably give it a good run for it's money BUT remember that scooby's got 4WD, twin turbos and power curves everywhere! Going back to the original post, I don't think it's worth tuning an NSR, it would probably be a great 10 minute ride but a LONG year rebuiling it! If you wanna go caning supercars why not save up for an RGV/RS/NSR 250 if you want a stroker, or just get a 400.

ctyson · Guest

good point but i thought we were talking about a nsr 125??

G · Guest

As I mentioned earlier I don't reckon the original post was actually *that* serious anyway

batman · Guest

em ill think youll find that an impreza doesnt have twin turbos there is only one which is a standard garret roller bearing turbo running between 9 to 10 psi boost @208 bhp you plank

Hi Viper
Funny this, but I have a Minari as well, that is how I know Sean and Andy and have seen the Delfino. Mine is still alot more kit than car, and my father thinks he will be getting it as a retirement project (I have too much to do at the moment). I think I was their nearest customer (only about 4 miles away). I am using an Alfasud Sprint as a basis for mine. I have a pair of Alfa 33's as transport, but one (a P4) I drove through a deep puddle and wrecked the engine. I have got a new engine to go in, and pulled the old one out over Christmas. I will probably fix up the old engine and put that in the Minari eventually once it is registered (ie, get it registered first with the engine that matches the doner car documents and chassis parts).
They closed down Minari Engineering as a company and set up a new company. They bought the moulds from the old company and in theory could still build more of them. The Delfino used the basic Minari body tub but very heavily modified. They built it as a one off prototype for the guy who is now talking about selling them.
The Minari is still in production by a totally seperate company, but this is being build using the moulds from the original car which Minari sold off years ago. This was built using Alfa Sprint rear lights and Citreon AX headlights, and with fixed side windows. I know they have revised the car a bit but not sure what they have done.
All the best

To say there are not many Minari's around (they probably only made about 300), it seems really odd that we both own(ed) one!
Small world!
My car was Alfasud based as well, as it was one of the early ones made, i think it was car number 26.
Are you a member of the Minari Owners Register?
Have you ever been to the Stoneleigh kit car show in the last 3years, as we may have met!!

Keith · Guest

Hi
I am not in the owners register. Should join really. They made alot less than 300 (just under 100 I think). Went to Stoneleigh a few years back, but more than 3. My car (just looked in the boot!) is chassis number 20093.
Are you at Uni in Oxford? My brother is at Oxford Brookes at the moment.
All the best

The only thing I know about the delfino is that the bloke Marx placed it on double yellows and it got impounded. He was wetting himself thinking it had been stolen until he found out it was impounded. Nice car. I didn't realise you were a mature student vicky.
