Hi guys, not really the place for silvias, but nissansilvia don't seem to share the hypergear love like you guys...
I finished fitting my hypergear ss1pu to my sr20 yesterday, and have finally been able to give it a bit of a drive. It's going in for a tune on Wednesday so I'll be able to put up some results after that.
So my old turbo was a 3071, which was a bit too laggy, but kicked hard when it came on; I decided that I wanted something a fair bit more responsive without sacrificing too much power, I was looking at a 2871 but have read that the quality is heading downhill blah blah, etc... When I found this thread, and read through all 442 pages, and spoke to some other members and eventually decided that the ss1pu was going to suit my needs.
It's an extremely different car to drive... before I would put the foot down in 2nd and have the wait/anticipation of full boost; which was great at the time, I'd never driven another turbo car (apart from diesel utes), so I thought this was the bomb. Until yesterday I hadn't driven a car with a responsive turbo either, so I went into it unsure what to expect. At first, I was a little disappointed... power delivery was so smooth, it almost felt underpowered because it just didn't have the same kick as the old turbo; but as I drove further, I started to enjoy the difference. It feels like this turbo makes positive boost pressure around 2,000rpm, and still pulls right to 7,000, its like having an extra 2,500rpm of boost which makes the gears feel endless. Still yet to see what it's like on long trips, 3,500rpm at 100km/h I dare say I'll be at around 12psi Anyway, results will be up soon, hoping for 220kw @ 18psi on 98, anything more than that is a bonus, anything less, well that's life, it's still a bit of fun.
