45,000 miles on BPU! Still going strong!
I have now sold my Supra and I though I would report on my experience of BPU.
I bought my car at 82,000 miles (nearly 3 years ago) and sold it at just over 127,000 miles.
When I bought it, the mechanical mods were just an induction kit () and a rear exhaust. My Supra had the top speed limiter (112 MPH).
I modded the Supra to BPU straight away and the car has been very good to me! The only problems were a leaking Boost pressure tank when I first had the BPU mods and a dodgy coil pack clip that caused misfiring (code 14) about a year ago.
I ran the car up to 1.2 bar with occasional boost spike to 1.3 (I used high boost gain/duty).
I didn't have an AFR gauge but have used a dyno a few times to make sure everything is OK.
I always changed the oil at every 3-4 thousand miles and stuck to semi synthetic 10W 40. The car has never smoked or suffered from cold start smoke from dodgy valve stem seals. When I bought the car there was a tiny bit of oil in the intercooler pipe (which I understand is normal) and this has stayed the same. The car was still pulling as strongly as ever!
I did stick to Denso IK24 iridium spark plugs on my car as I found my car to be slightly more responsive than the copper equivalent. But Denso's are expensive and only good for 10-11K miles on my car. They have bad reputation too for breaking up! Lol!
So I have definitely enjoyed my Supra ownership! A decent car that is as quick as cars costing ten times as much and reliable!
Thanks to everyone in the forum who has helped me out and it's been great to meet loadsa good people in the meets! Thanks to the Mods who do a very good job! Cheers to Terry S who introduced me to Mark @ Phoenix who looked after my car well. And thanks to Absxxxx who helped me out quite a few times too!
Cheers,
