Turbo change

[jetpilot]

Hi guys, looking for some advise on a change from my T78, great turbo but a little laggy for my requirements.

I need something that will bolt on to the same flange and be roller bearing, would like to make 400 rwhp.

What should i be looking for in respect of sizes (ar etc)

I was thinking T04r,z or GT35r, RX6, any other suggestions or advise from people running them or similar??

T04Z for the the win, The R model is bush bearing, but if want really fast spool up go for the GT35R and run 1.1 BAR to get 400rwhp on a street port

Is there different variants of the 35r, or is it just the same specs throughout?

You can different size hot sides and t3, t4 or tial v-band.

So whats the best one to go for with reagrd to hot side? I presume your talking housing size?

I think i would go for the t4 twin scroll option which i think is 1.02 ar. I think it\'s the biggest option but still very little lag.
The other intresting one is the tial v-band i think it\'s 1.0ar but the cost goes up as you got a tial housing and a non regualr manifold for that.
