You'd make more boost if you were. Anyhow. As far as single turbo conversions go, I was originally gonna stick with the CT12's, back in the day, then I got talked into a larger single conversion. So I went ahead, and purchased what I thought was a 600hp GT40 ball bearing turbo. I have since found out that this turbo is actually closer to a 700 hp turbo and is a touch too big, with all things being equal (like cooler pipes and appropriately sized manifolds) it doesn't come on boost till about 3500~4000rpm. This is a slight problem. So, I've done the maths and worked out that the exhaust housing needs to be changed, it's a 0.82 a/r at the moment and it's going to a 0.63 a/r exhaust housing. That should bring the boost threshold down to about 3000 rpm. Which in my opinion will work fine, because once this big turbo charger comes on boost, sit back and hold on. It hits in pretty hard, but as was said before, a 1g off boost isn't a particularly big slug, it still moves, but not as fast as it does on boost. Another thing I've found too is that twin entry turbo chargers come on boost earlier, so looking for a gt4 exhaust housing that will fit onto a ct26 from a 7m would provide plenty of go, providing that the exhaust wheels are the same size, which isn't necessarily a given. The other option might be, try and get a ct26 off a late model 1jz... There's something that would move. Anyhow, that's my 2c (more like 50c after this essay). If anybody wants to email me about this, email celica@sco.net.au. [Report message to a moderator]
