Hi guys,

I had an impulse buy and splashed out on a new turbo, it was on clearance at the local store and picked it up for a great price, from my limited (and to be honest slightly rushed) research it seemed to be suitable but wanted to check with you guys on what you thought.

I realize likely all the information I need is somewhere here on the forumn but thought it would be easier to get some up-front feedback from you guys.

Here is my current setup:

13b Full Bridgeport
big injectors
Microtech LT-10s
Flowed s4 Turbo (9 psi)
Turbosmart Ultragate 38mm External gate
Big intercooler
Power: 280HP@wheels freshly dyno tuned

I just splashed out on a turbo at the local dealer (was at a clearance $$rate) and did do some research prior however I would like to check if I got the right one for me and if it will work fine for my application.

I am able to return it if its not "perfect" but moreover I want to make sure its suitable for a rotary engine and can do the job.

What I am wanting:
good spool up 3-4k rpm, good/more power, street friendly

Here is what I purchased:

Borg Warner s300sx - Model: #177281
Compressor
Wheel inducer 66mm
Compressor outlet 3.00
Compressor inlet 4.00
Turbine
Exducer 73mmTurbine outlet 4.00 V-band
Housing T4 open flow .88 A/R
AND...Turbosmart Pro-gate lite 50mm v-band Wastegate (with 14 psi spring)I will be having it dyno tuned again immediately after of course.

Look forward to hear your feed back, did I waste my time? should I take it back? should it do the job?

Thanks

Is it the s366? If so, it's too big for the spool up you want. Look into s200 series.

.88 ar is fine for a 3-4K rpm spool range. However you'll be looking to be on full boost in the 4K rpm range, if it's a twin scroll hotside with matching manifold it'll aid in getting there a bit faster.

being bridgeported I wouldn't think going smaller would be of benefit.....just be a mismatch of parts.

Borg's .88 t4 housing is undivided. Most of my limited turbo knowledge is based on the diesel performance world, but am I wrong to think that the .91 divided housing with a matching manifold would be a better option?

100% the better choice.

This is in the single turbo sections as well and mr. Howard Coleman, who I am a believer that knows about turbo, answered this question. You just have to pay attention what he posted there.
