PPG or PAR for B4 box.

[Sti_wagon]

As the title suggests, im wondering if you can get PPG gearsets to suit a 99 b4 box?? Anyone know if the WRX sets can be used??
Approximate prices if people know too???

If not, whats my best bet to match up to a 99 B4 engine????

I'm pretty sure you can use a wrx gearset in the B4 box, you just have to make sure you get the right one as there are a few available depending on the model year. Best to speak to your intended gearbox builder to find out what is suited to your application

Which set do I need for my WRX when ordering?

1994-current 5 speed WRX Owners take note.
Subaru Gearboxes have an unusual variation in the manufacture of 1st and 2nd gear and 3rd and 4th gear on a different year that can cause problems when fitting gearsets. Its therefore very important you know what year gearbox you have in your car. This has become difficult at times as most Subaru owners are now buying a PPG gearset after breaking a few standard gearboxes and they may have replaced the gearbox with an entire gearbox from a different year model vehicle.

Please note the information below before ordering.
MY 94,95,96 up to 6/97 Gearboxes have single synchro 1st and 2nd gear up to 7/95
Single synchro 1st , Double synchro 2nd on 8/95 on
(must update to 8/95 double synchro 2nd gear !)
Single synchro 3rd and 4th gear to 7/95
MY 97,98 (7/97 to 7/98) Gearboxes have single synchro 1st , double on 2nd, 3rd and single on 4th.
PPG 1-2 sets are a straight C/over . The 3 and 4th sets require a 4th gear synchro ring to be used on 3rd gear which we convert to single synchro.
MY99 on (8/98 on) have singls synchro 1st, double synchro 2nd, double on 3rd and single on 4th. 3rd and 4th synchro's are different to the pre-98 boxes and cant be used.
OUr 1-2 sets are a straight fit , but same as the pre-98 sets we now convert 3rd to a single synchro and it must use a 4th gear synchro ring of post '98 type.

cheers for that hendo.
any others know if the b4 box is same or very similar to a WRX box of the same year???

They are similar to the same year STI from memory, with a 4.44 ratio.
Although if its a 99 B4 then it might have 4.11's as it will be jap spec

I'm pretty sure it has the 4.44 ratio.

I just had a 1-4 PPG straight cut synchro gearbox built by S&J in Adelaide. Sean does a great job, and helped me out on freight cost too. All up the cost was about $6.5k. $5.7k was from S&J for parts & labour, and this included the gearset and synchro hubs required for the older boxes, mine was an RS box. The rest of the money was freight and installation back here.

If I had another chance, I would have paid the $350 x 3 extra for the billet forks also.

yeah I thought it should, but I wasn't 100% sure.
