Whack on a 3 inch straight thru exhaust, intercooler and manual boost control and then your Toyota will stand on end
I've done the exhaust so far and the results are awesome
ive done everything bar the intercooler and fuel screw. im currently running 12pounds without a pyro guage. once i have one fitted i will play around with the screw
good on you, i find it disheartening to see people gather info from members on here and piece it all together and charge a rediculous price for the product after and all while slagging anything made from china saying anything made in china you run a enevitale risk of catastrofic failure, yet they use them as a core too. i was wonderring why they have been so quiet. i thought this forum was to help each other out and trying to keep it the do it yourselfer or at least as cheap as possible. i think a t3 option is a good start . can hardly wait to here dougals input on turbo options he has good number knowledge and isnt here to rape anyone.
I wouldn't say that at all. Graeme with the Gturbo has collected, tested, reverse engineered and engineered his way to the Gturbo line. He is a professional engineer who has done a monumental amount of behind the scenes work. Work that could not in any way be gleaned from other peoples postings on forums.
If I was producing and selling turbos they wouldn't be any cheaper than the Gturbos.
I have a very simple rule for any parts. If you can buy them, then buy them. It will work out a multitude cheaper than any build or piece together option.
So mapping the 16g large even at 5000ft it is a tad away from surge with 21psi at 1600rpm. That doesn't seem so bad actually. I did find a link Doug for a twin scroll 8.5cm tdo4hl 20t that has turbine measurements that don't correspond to an HL, but is still quite interesting. I have no maps for the 20t but it's just the inducer that changes by 1mm so.... More room on the right?

I didn't miss that you mentioned the 19t would be great in a compound set up. I was thinking the same thing. After doing a bit of reading on the td42 guys using the td05 it seems to respond reasonably, but not awesome. I think it really only responds with the really small housings. Your very right that the 19t is a more efficient compressor as well, but it just can't flow enough air for the top end, not that most folks rev it out that high though. The HL is a physically much smaller turbo for a compound set up for fit,ent as well vs the td05. It would be cool to see a twin scroll housing used sometime though. They do twin scroll td06s and it doesn't map to bad in a compound set up with the 20g providing the small doesn't boost too much, but they are pretty expensive and a cheap holset makes more sense. Somehow I get the feeling like I just talked myself out of something. What is the CMs of the 1hdt housing anyhow?
