1.01 twinscroll would give you better spool ...................

i agree but my research gives me an idea that the 106 overall will be better. the 101 would reach full boost at what rpmīs ? under 3000 rpmīs ? will it hold to 7000? i would like to reach at least 350 whp

You can get 350 hp with a BNR Stage 3 upgrade turbo easily. No need for a full GT3582R. A GT35 is for if you are looking at 400-450 HP, which can be done at 14-16 psi all day.

Now the GT35 turbo has a smallish exhaust side for a rotary, which lends itself well for quick response. However, you will still only reach full spool at around 3500-4000 RPM. Dependent on which exhaust side will determine how long it holds the power.

A 0.82 T3 will pull like a freight train from about 2700RPM and run out at about 6500 RPM.

A 1.06 T4 Divided will come on strong at 3500 and pull past 7000 to redline.

The exhaust size is smaller than a P-trim turbine, so it's not a true T4 turbo. The GT35 used to only come with a T3 housing until it became popular among RX7 owners, then Garrett made the T4 housing that really is a T3 with a T4 flange.

This is a dyno chart off of Banzai Racing's FC vert with a 13B-RE. It made close to 450 hp on 15 psi.

You can see full boost around 3700 RPM in the graph.

A good person to ask is Elliot at Turblown. They have a really good turbo called the TX61, which is basically a upgraded GT35, so it's better suited to a rotary. If you want the pinnacle of response and technology, look at the Borg Warner EFR turbos.

the 106 t4 is exactly what i want , i wrote 350 whp at least because thatīs the minimum that i want if i can get around 400 hp thatīs perfect, and if i get boost by 3500 up to the 7000īs itīs perfect for what i want, what should i run for injectors ? i think the 800-1600 should be enough but not sure

850cc primaries and 1600cc secondaries is fine for your goals. Use the search and check out the single turbo subforum. There are more than enough answers there. For injector sizing, check out this thread.

so that was helpfull , thanks for that , anybody can tell me witch seals are better , iīve read that oem are the better in 2mm and that itīs not worth getting 3 mm, also that oem seals and stock internals are good to about 400 too 450 . 450 sounds too much on stock internals but iīve also read that the 350 to 400 whp range is easily handled with a good tune
