hiya chaps, planning a vts conversion was just wondering if i kept my vtr gearbox if it would set off like a rocket with the vts lump but be slower top end as im not fussed about top end. Thanks tom
Vts engine Vtr gearbox

#1
-
#2other way round mate
-
#3what my vtr engine with a vts box do u mean pal
-
#4vtr box has the highest diff ratio
therefore you will get a higher top speed
and less get up and go -
#5have a vts box aswell
-
#6dont get me wrong it wont be slow with an 'r' box but 0-60 will be reduced as you need to select third to hit 60, in an 's' you dont
-
#7buy a vts lol
-
#8No mate.Quote:dont get me wrong it wont be slow with an 'r' box but 0-60 will be reduced as you need to select third to hit 60, in an 's' you dont

You'll hit nearly 70mph in second gear (with a VTS engine limit) using a VTR box. The reason the acelleration will be slower is because of the lower final drive compared to the VTS box, which has a much higher final drive. -
#10VTS FD = 3.938
VTR FD = 3.765
VTR box = slower acceleration, higher top end (as long as you have the power to get there)
VTS box = faster acceleration, lower top end
But as shown on another forum recently - the gearbox won't make a huge amount of difference to the time it takes you to reach a set speed (0-60) or a set distance (1/4 mile) -
#11thanks chaps
-
#12another quick question. i have a 2000 mk2 vtr with the silver top, will a 03 plate vts engine have the same plug ecu as mine.
-
#13oh rite fair enuff my understanding was that no matter what engine you had in the car you gearbox would ultimately decide when you had to change gear (i know it sounds silly) eg a 1.1 with a 1.1 gearbox would change gear at the same revs as a vts with a 1.1 gearbox. My understanding was you couldnt hit 60 in a vtr in second???? maybe its my mistake though lol
-
#14Well the VTR has a limiter of around urrrrrrmmmm i dunno its late so if this is wrong thenQuote:oh rite fair enuff my understanding was that no matter what engine you had in the car you gearbox would ultimately decide when you had to change gear (i know it sounds silly) eg a 1.1 with a 1.1 gearbox would change gear at the same revs as a vts with a 1.1 gearbox. My understanding was you couldnt hit 60 in a vtr in second???? maybe its my mistake though lol
- but i think;
VTR has limiter at around 7250rpm but the VTS has a limiter of around 7850rpm.
And iirc in a VTR in 2nd on the limiter you do 59mph (even if the speedo shows 65 lol).... so those extra few revs make alllll the difference. -
#15vtr rev limit is 6250
vts is 7250 i think -
#16personally id go with the VTS gearbox shouldent be that expensive to do and you probably could fit it yourself
-
#17Rev limit ultimatly decides when you need to change gear, or when the power drops off.Quote:
oh rite fair enuff my understanding was that no matter what engine you had in the car you gearbox would ultimately decide when you had to change gear (i know it sounds silly)
Two different engines (IE 1.1 and VTS) with exactly the same gearbox/tyre sizes will go at the same speed for a given rpm. However - the VTS will be able to rev higher. Therefore for the same gearbox, a higher rev limit means a higher speed in each gear (assuming you've got the power to overcome drag/ wind resistance etc) -
#18The engine and its limiter will determine the RPM you can go up to. The different gearboxes will then determine the speed achievable at a specific RPM. Therefore, the VTR (car and gearbox) cannot reach such a high speed in second gear due to its RPM limit being set so much lower than a VTS engine. Does that make sense?Quote:oh rite fair enuff my understanding was that no matter what engine you had in the car you gearbox would ultimately decide when you had to change gear (i know it sounds silly) eg a 1.1 with a 1.1 gearbox would change gear at the same revs as a vts with a 1.1 gearbox.

#19Exactly, well said.Quote:Rev limit ultimatly decides when you need to change gear, or when the power drops off.
