much wider curve than the vzr..id say its lovely to push on very easy to keep in the power band..have you got one for a standard gti?
i have one of my vzr standard(had an induction kit on which was hindering it) il post it up we could do a comparison.

I re-worked the BHP figure using some equation I saw DBull and others talking about a few weeks ago..

Torque x BHP Peak RPM/5252
137.4 x 6800/5252
=177.9 BHP

The Autech Primeras supposidly had a 180PS engine so this 177.9 BHP figure would suggest that both engines were the same and the Autech Pulsar is actually slightly more powerful than stated.

This means the quoted torque is either lower in reality or the quoted BHP is higher in reality.

That torque output applies to that specific rpm, it drops off a little above 5200rpm so the same formula can allow use to see that:
172.5Hp = torque * 6800/5252
Torque = 133.2FtLbs
 
I was having a look at the engine the other night and had the grille off, and i noticed there is no power steering fluid cooler? Car gets weirder everytime i look at it. I had wondered why the PS reserviour was hot, so i made a heat shield for it, but it turns out it has no cooler.
 
My n1 made 182bhp and 155whp
Not to bad for a 12 year old car on dirty irish fuel
Only modd was a decat and nismo back box

I wonder what it would make on Tesco 99 or Shell Optimax. I also wonder what it would get Jap fuel as its higher octane then UK apparently
 
Yap i had planned on running it on pro boost and topaz petrol as i find it best

Completly forgot and ran it on crap from some run down auld place :(

But i wasnt complaingin with the figures at that

why run it on topaz petrol and not maxol?
surely with maxols E5 it would be better than topaz fuel, seeing as they advertise it at between 97 - 99 ron??
 
I have heard that the VZR N1 has shorter gear ratios than the regular VZR..?
(as evldan said they were the same on the first page)

Vzr n1 version 2s have a shorter gear box allowing it to say in the power band :P
 
Yes version 2 are hydraulic too.

On with evildans list the n1's all had different pistons,
Knife edged balanced crank,
Flywheel was diff,

no fogs,
winding windows,
no kit,
spoiler,

Version 2 also has

different tuned map on the ecu,
diff gearbox ratios,
diff interior,
no sound deadning,
rear wiper removed,
vanity mirror removed,
 
VZR & VZR N1 flywheels are the same.

Oh and the exhaust manifold that is on the Autech SR20...looks very similar to the one that is fitted to the stock P10 high port SR20.
 
hmmm fly the same I was told different.... Most likely your correct tho as one of them was weighed by POC when he took his out and he said it was the same too....

Really hard to know exactly what the specs of them were everyone has a different opinion.... I'm not so sure about the version 2's gearbox either that all had different ratios just those fitted with nismo parts from factory were different
 
Normal N1 32010-2N519 transmission same as VZ-R (32010-2N509) just hydraulic type
VersionI Nismo trasmission 32010-RP809 09/1977-10/1999
VersionII Nismo transmission 32010-RP810 10/1998-10/1999

These are the only transmissions. You have more chances to get the lotto that hitting on a nismo one.
VersionII has better midrange and uses single activation point 6700 for both cams.
Top power is the same for both Versions.
