now i have a turbonetics t3/t4 with strim on the compressor and stage1 turbine
i am bosting 15 psi
i havent dyno it but i want more power.
shoult i just get a stage 3 tirbine or should i get another turbo.
i have read about the hx35/ and hax 40. they seem to be nice and it is a very good price on them to.

why i want to have another turbo is because i have mouch backpressure.

my setup is on a b16a1 with itr cams, a shity ebay turbo manifold tha i will throw away and probably get a ramhorn
a big intercooler, 2,5" interccoler piping
38mm wastegate 3" downpipe
portet TB and intake and the head is portet to
550cc injectors
CP 9,1 pistons and eagler rods
i am reving 8800 but it loose power after 8500

thanx

I have no idea WISCH one. BUMP

 

Get a better manifold, then have the car tuned. You have 400+ whp potential with your current setup.

 

my car is tuned. dont know wisch program they used. but it is well tuned.
yes a better manifold would be good.
but what about the turbo?

Dude, don't be a dick.....he's from SWEDEN.

 

yes precisely we dont have it easy.

 

Some questions for you........why do you think you have to much backpressure??

If you have not dyno'd the car how do you know that the turbo isn't working efficiently at that pressure ratio?

What size exhaust do you have??

Do you have a catalytic converter??

What is the size of your turbine housing and turbine wheel??

 

because when i was boosting 6 psi i had 18 psi in backpressure. now when i am boosting 15psi the backpressure is probably way more.
iam going to dyno the car in the spring. but what is good numbers, what should i expekt.
the exhaust is 3" all the way from the downpipe, the wastegate goes in to the exhaust to, it goes in under the oilpan, i have no catalytic converter
it is 63 AR and the turbine is 1,9 * 2,28 (stage 1)

 

I'm no expert, but I would guess ~340-370whp. Just a guess..........

 

what do you think about this porting. it is a original ba16a1 intake.
it is not done jet
