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/top...e3-gearbox
