agruyich New Member 2 Member For: 7y 6m 21d Posted 28/09/16 03:35 PM Share Posted 28/09/16 03:35 PM Hey Guys, I Recently purchased a BA XR6 that was orginally N/A that has a had a turbo conversion but on the N/A engine. I have read a few threads and no some of the guys here have experience with turboing the N/A engine. As the car has already been converted, I am looking to tune the car now. What would be max amount of boost the stock engine can handle? I am assuming it is around 7psi or so? Has anyone ran 10psi safely on N/A internals? I am looking for around to have around 250rwkw to 300rwkw. The car already has a Walbro fuel pump installed and I have a set of 42 Ib injectors not installed though. I understand with N/A internals it will never reach 300rwkw, but in your opinion what do you think the max would be I could push it? Also how much can you run through the T5 and standard clutch before it sh*ts itself? Plan is to slowly build the car and when the engine sh*ts itself purchase a XR6T engine with T56 box. Planned mod list is as follows .Walbro fuel pump .42 Ib injectors .Turbo back exhaust .Valve springs (no on N/A engine though) .SCT X3 Flash .K&N Air filter From experience do you think above mods will support 250rwkw to 300rwkw? Also for BA's are the brakes the same for N/A xr6 and the xr6 turbo? Im pretty sure the brakes changed on the BF models? not sure though! Anyone recommend a place in melbourne to get car tuned? From what I have read nizpro is good? Cheers Adam Link to comment Share on other sites More sharing options...

I don't think you'll be able to safely push that motor past 250rwkw on 98 pulp. That box won't handle it either. Cris is on the money. Save up and get a bf11 onwards block and a t56 and then push it.

BF onwards turbos have bigger discs but same calipers. That's all for the front - not sure if BF turbos had different rears to N/A. Link to comment Share on other sites More sharing options...

What were they standard? I think that's a weird size. Link to comment Share on other sites More sharing options...

I have the same on mine- rear is larger diameter than the front but thinner. these were on the au3 t series. Link to comment Share on other sites More sharing options...
