Thanks for this :) gives me something to think about thats quite a big drop in revs from 4th to 5th! knowing me though I'll probably fit it anyway :P I'll keep the old dpa though just in case, I'm finding myself driving a bit slower nowadays maybe I'm getting old  :grin: a nice long cruising gear might suit me then just use 1st-4th for faster driving

Sounds ideal, but where as you can now plant your foot to overtake, you may find it requires a change of gear to overtake. You would hav the DPA box and you can easily change 5th over in around an hour.

ASD box with DPA 5th looks better. Green line shows DPA 5th



Gearbox:-  ASD+DPA 5th
Tyre:-       195/50-15
-------------------------------------------------------------------------------------------
Top Gear gives 25.537 MPH/1000 RPM and a top speed of 165.989 MPH at 6500 RPM

Engine speeds in top gear:-
    30 MPH = 1175 RPM   40 MPH = 1566 RPM   50 MPH = 1958 RPM   60 MPH = 2350 RPM
    70 MPH = 2741 RPM   80 MPH = 3133 RPM   90 MPH = 3524 RPM  100 MPH = 3916 RPM

Top Speed in 1 gear = 42.101 MPH
    And changes into 2 gear at 3829 RPM dropping 2671 RPM
Top Speed in 2 gear = 71.468 MPH
    And changes into 3 gear at 4373 RPM dropping 2127 RPM
Top Speed in 3 gear = 106.218 MPH
    And changes into 4 gear at 5114 RPM dropping 1386 RPM
Top Speed in 4 gear = 135.017 MPH
    And changes into 5 gear at 5287 RPM dropping 1213 RPM
Top Speed in 5 gear = 165.989 MPH

Yeah that does look better, I'll probably fit the asd for now to see how it feels and open up the dpa to try and get my head around how it works, most I've done on a gearbox so far is change the tower over!

do you know If I'll need to change the tower on the asd to fit the mk4 cables?

Yep, it may need the bottom bush under the tower out of the DPA too.

I could use the 02a type 02j tower I have on my dpa already though right? that was a straight swap for my old 02a one. sorry I know you've already explained it earlier in the thread but I'm confused as I cant see any significant difference between my old 02a and the 02j one I swapped it for

Just found out my mk4 tower part number is  02A 945 413 C. were the early mk4 towers an 02a part number or is this in face a mk3 02a tower?

edit that part number is actually for the cap with the reverse light plug on it. Think I may have a mk3 tower  :sad:

If it has a black cap reverse switch it's a mk3 or early mk4.

What are you trying to not do? It's not a proper 02j one.

Just wanted to know if the ball type endlink mk4 shifter would fit this tower as I'm going to the scrappy tomorrow so I could pick up the right one if not. I'm thinking it wont though looks like a different setup

As I said. Its a completely different tower. Are you trying to save money? It's like your trying to use what you have with a mk4 shifter.

You need a matching shifter and tower. You can't get it to fit the mk3 one.
