lozza Member 121 Member For: 15y 4d Gender: Male Location: Westside Melbourne Posted 03/07/10 10:56 AM Share Posted 03/07/10 10:56 AM Hey guys.I am looking at trading the old ba to get a BF MkII XR6T with the typhoon internals and the ZF6 instead of a T56 in my ba. Ive been told high 300's they are good for but I've also seen a fair few in the 400+ club. So what is the limit to this engine. I'm only considering it because it has every option besides leather and a friend is selling it at dealer trade in price. Its stock standard but I will have a rapid 4.5 kit, 4" turbo back exhaust, 2.7L surge tank, 60lb injectors, ported wastegate, actuator and a Xcal3. Hoping to see 400rwkw or more and an mid 11s pass.

And turbo will run out of puff... Link to comment Share on other sites More sharing options...
radiorahem Member 134 Member For: 16y 2m 2d Posted 03/07/10 01:28 PM Share Posted 03/07/10 01:28 PM Mate its a gamble. But really the same bloody question that has been asked 6 billion times before, oh what power is this going to get me and will the car still be safe. You have read that other people push big numbers with certain set ups that other cars have failed with, if you are going to do it just do it be a man because no one who is sane will give you a guarantee. That is the reason this site has got stale same dumb questions repeated. Link to comment Share on other sites More sharing options...

I'll just leave it with danny springy again and I'm sure he will work his magic. He managed 310rwkw on my standard ba clutch and valve springs so I'm sure he can squeeze 400 out of this.

Mine ran on 380 rwkw before I went stupid . But saying 400 it is hit n miss. doris got 600rwkw on standard interals so it is luck of the draw Link to comment Share on other sites More sharing options...
davidg2152 Donating Members 98 Member For: 18y 1m 16d Posted 03/07/10 11:53 PM Share Posted 03/07/10 11:53 PM I have that exact model, 362rwkw, no issues, great to drive. However that is as far as I am going without doing a rebuild for reliability long term. Link to comment Share on other sites More sharing options...

Wouldnt mind some forgies and a GT42 but the bank wont allow that at the moment. Link to comment Share on other sites More sharing options...

Posted 04/07/10 06:25 AM Share Posted 04/07/10 06:25 AM im on 350rwkw same motor, but a built auto. so far so good tunehouse gets 450rwkw+ out of em, but us melb boys tune it differently so 400rwkw you might get after you upgrade turbo/manifold.
