which final drive???????????

[dhdavectr]

^^ yes it will fit. Personally i don't rare the combination of the 98 spec box and a b16 engine due to the jump from 3rd to 4th and the lower torque of a b16.
If you don't like the ratios could always remove the LSD and final drive from the 98 spec box and fit to your b16 box.

If you don't spend all your time cruising on the freeway, then any extra fuel used on the occasional freeway trip is more than made up for by using less fuel during traffic light driving. Urban driving is more about load/throttle, than it is about rpm, and you will use less fuel with the shorter gears.

Good info thanks!

Hi there! If changing to a 4.9 final drive what type of gains (in seconds on standard EK9) in acceleration would you expect ie 0-60 and 0-100 for instance and also how much did it cost for the conversion?

Cheers

Sorry havent timed my ek9 from 0-60 or 0-100 so dont know what improvements have been made. Wel I went with the Mfactory 4.9FD with their own synchros and bearings and Torco MTF. I bought it straight from Mfactory from their website and came from USA. cant remember how much I paid in total. I paid about £200 to get it all fitted with a lightened flywheel, spec clutch and new innovative engine mounts! The prices are still on the mfactory website but import tax was about £140 on all items!

.

X2 id also like if someone coud varify some indication of gains

See above mate!

Would also like to know that ^

See above mate!

Quotes i've recieved

£150 labour to remove and refit box
£150 labour to strip and rebuild box

Plus any parts

Good idea to do bearings if needed and syncros

The main bearings that are worth changing (if needed) come to about £100

And syncros are about £150 each? Think there was 3 in total 2nd - 3rd, 3rd - 4th and 4th - 5th.

Final drive was approx £420 to the door with import tax

Not sure about times but you gain 12% more power and torque with final drive. Although your engine doesn't actually make more power for a B16B it would "feel" like your engine has 207.2bhp and 129.92 ftlbs... Substantial increase in performance basically.

HTH

Good info mate!

How did you find it ordering it from the states ? ok? how much did the import tax sting you ? Is there no one in the Uk dealing in this stuff ? I'm interested in improving the gear ratios to keep it on the boil .

thanks Garry

Ordering straight from Mfactorys website was flawless, quick delivery, great prices, great info and everything was mint! Import tax was about £140 but that was for the FD, synchros, clutch, flywheel and solid shifter bushings which I all got from Mfactory.
Yea Funky power (scotland) will supply the stuff but I checked and their prices were alot higher than straight from Mfactory and delivery was way more too!
Its a very worthwile upgrade!

will a 98 spec gearbox fit my ek4 b16a

yes!
