I can't find info on them being BW. It was all over the place when they first came out and now I can't find it nowhere. I guess they don't want people saying it's BW.
If someone finds the info please share.
Personally I have not used them. The feedback I've recieve on them has been that you can spool a larger turbo quicker than its Garrett counterpart.
there is a thread on Supraforums in the Florida section where one of our local shops ran tests on these. The results was a tad better such as...
Tubonetics is just another distributor that sells turbos, such as Precision, ITS etc. They, used to sell Garrett turbos until Garrett dropped them. So for a while they had to buy higher price Garrett and use other kinds of no name turbos which only made their business go down the drain. They...
NOpe, to my knowledge BW has done tons of R & D and have some up with the S design wheels which is what is used in the GTK. Although bigger they spool as quick as the GT wheels. If I recal. But I am 100% sure the GTK are BW wheels.
Kinda funny, my 3rd hits the rev at 7200 but my 4th lets it ride to 8200....
I confirmed that one time on the highway running with a Supra. I was on 4th pegged to floor and did not notice I was approching 150mph in 4th. My 4th is supposed to top out at 129. It got me there. It's a stock ecu.
Actually 25psi....for the record
Jay, If we sum up everything you are doing to your engine, you're pretty much turning your 1jz engine into a 2jz engine. As a recommendation, cut your loses and go 2j and be done with it.
we finished up another 1j 240sx 2 weeks ago and I love how them twins feel.
We had a dyno day this weekend and put his car up and 300rwhp @11psi.
I love them twins, they are a whole lot of fun, if you can manage to replace them then do so, if not it's single time and get ready to spend.
w58 can hold upto ~400 ft lbs of tq in a 3800 car (sc300) in 3rd gear which is the weakes link. at that level of tq a 1j is approx in the 450rwhp range. Now take out ~1000lbs of weight and the tranny will hold pretty good.
That is a supra 1j converted to front sump and a 95 MKIV w58 tranny. (has the extended shifter necessary for this swap). I ordered a gt4082 from presicion.
I am doing the same set up that I have on my lexus on this 240. Put it up to 450-480rwhp with a long power band. And yeah no cams, just...
