End of an Era...Which Gearbox/LSD combo

Right guys....the greddy Emanage Ultimate is too limiting on forced induction setups but is much more suited to N/A remaps on the Prelude. This is the words of an experience tuner who tunning my car.

So



Im doing it...



ATTS is going. :cry:









But no fear. Socketed P28 ECU and OBD2 to OBD1 conversion, ATTS delete plates and my choice of LSD gearbox.



So no the question is

Do i go for a Accord Type R U2Q7 Helical box that has wanky non Prelude VSS and shorter ratios
or a normal gearbox with an Mfactory LSD (Quaifes are $$$$$$$$$$$$$$)


Being a supercharger the power is more spread out so a shorter ratio gearbox isnt absolutely necessary as ill be producing torque out my ass throughout the rev range.



Suggestions please.


Oh and i will have a Greddy Emanage and Boomslang harness up for sale you Type S/triptronic Sportshift owners.

Or, a 'normal' box with an ATR diff in it ;-)
Don't be vexed about the VSS, mine was a simple gear swap. :)

OK, I have 244bhp rather than the 300 odd you're wanting, but I find it a great balance of grip and day to day drive-ability, one of the best mods I made IMHO.
I liked the ratios of my original 'box, hence why I kept it. Still allows me to munch the motorway miles too 8-)

Just to add another factor into your choices, I'm pretty sure you can split the VSS, using the U2Q7 bottom with the prelude top part, effectively giving you a prelude VSS that fits into the accords gearbox.

With the torque you'll have, I'd have thought a longer ratio box would be better though anyway?

^ Agree on both counts BTW. :D

Buts its limiting the superchargers needs......too many complications. Stupid modifications. i hate them.

I don't have the U2Q7, but I have the M2P4 which is AFAIK essentially the same, sans LSD. I think you will be much better off with a box with longer ratios as already changing into third gear just before 60 is a PITA on a sprint. With extra power I imagine it will get very tedious very fast, assuming you're going to be somewhere between 250-300bhp post tuning.

why not just get another H22 lude and sell the Type s to finance the build

Cheapo UK 97-98 M2V5. It has the lower UK final drive (4.062) and a longer 3rd :twisted: Then your choice of diff.

The gearbox in my 4th (the M2F5) has the same 3rd ger as most of the gearboxes but a shorter 5th ;)

and I agree while the lsd boxes have the "lsd" the ratios are not the best in the 4g 1st was pretty useless I know I was undertyred so it knocked out all the ratios and fook me was it quick it wasn't good on a run out on the motorway go for a h23 box drop the lsd in it if it will go in the extra torque will make up for the ratios
