XU10J4R gearbox help - Zxmad98 - 27-03-2019 Hey everyone I'm a newbie so sorry if this is in the wrong place! I have a citroen zx volcane project not a 306 I know but everything underneath is the same as I'm aware. I've got a 2.0 16v XU10J4R lined up from a 306 gti. I'm going to have all sorts of questions but first up what gearbox is best? Needs to hold power I'd like to build it up with a turbo. Cheers. RE: XU10J4R gearbox help - Mighty306 - 27-03-2019 Welcome along ZX mad. First, just need to clear up engine designations. The XU10J4R was in the 306 XSi, 406 and a number of other models. On the 306 it was never badged as a Gti. The GTi-6's got the XU10J4RS with a lot of differences and an extra 32bhp. Main differences are in the top end & also RS had different pistons for higher compression. The XU10J4R has a fundamentally good head (v similar to MI16 but with very mild cams n weak-ish valve springs). Bottom end is apparently capable of handling a lot more power. BE3 gearbox, incl the 6-speed from the GTi-6 will bolt straight on (as I'm sure you already knew). 205gtidrivers.com is a mine of information when it comes to modifying PSA engines n use of PSA gearboxes. https://www.205gtidrivers.com/forums/topic/160837-what-the-most-bhp-known-for-a-be3-gearbox RE: XU10J4R gearbox help - Zxmad98 - 27-03-2019 Hi Mighty306 thanks for your reply, I checked and the engine is from a 306 xsi, so definitely the XU10J4R unless its had a engine swap for any reason. I'm looking for the stronger gearbox I have a few (6) diesel zx's been told the gearbox has a better ratio but the standard diff probably wont hold the power id be looking at. What would be the best set up? Cheers RE: XU10J4R gearbox help - welshpug - 29-03-2019 diesel ratios will be horrible on a petrol engine. get a lsd like a 3j or tranx etc |
