As the title states ............ this is my attempt at making the ultimate Renesis turbo setup .
I've been running the Greddy system for about 6 years now and learned a heap from maximising that setup (See Brettus turbo and Brettus turbo 11 threads) but figured it was time to do something of my own design.
The engine : will be using my current engine . This engine has been doweled and had rx7 deep apex seals fitted along with increased oil pressure. However , once the turbo system is sorted I plan to refreash this engine as it is down on compression .
The Turbo :
This is a Garrett GT3582r unit . I chose this turbo after considering all the major brands . The main reason I went with it is because of it's relative compactness plus it had the options I was looking for . Other Garrett turbos I looked at ,that would also have fitted, were the GTX3076r, GTX3576r , GTX3582r . I settled on the standard 3582 for a few reasons :
*Discarded the 30 series when I realised they used the same turbine castings and CRHA as the 35 series so size is the same.
*It's more efficient than the smaller X76mm wheel in the range I want to operate it .
*With the design i'm looking at spoolup should be ultra fast , and I figured the smaller 76mm wheel would certainly go into surge without the benefit of a ported shroud. A ported shroud wont fit in a low mount design.
*The GTX3582r ,I felt, was just overkill for my whp goal .
*The cast compressor wheel is said to be more durable than billet when using pre turbo W/M injection.
*It's a lot cheaper than the GTX series
The design :
This is where I'm hoping to make some inroads into making the Renesis turbo a viable alternative to an REW swap .
*Lowmount
*The turbine housing is a 1.06A/R twin scroll fed from the end ports.
*Wastegating will be a single 38mm wastegate through the siamese port .
I'm sure this will raise some eyebrows and create some scepticism . The system has been designed around making this work and I'm excited to see if it does .
Goals :
Reliable 400-450whp
16 psi by at least 3500rpm
Factory drivability
Turbo on dummy engine .
