Oh I completely agree. Which is why some people choose a different route.

Yes, that is exactly why many people get a BNR upgrade. It is not as good as a full turbo replacement, but it is also not nearly as expensive or as complicated.

Do you also understand why the Rtek Stage 1 is better than a FCD? Some people contributing to this thread don't, but I just wanted to make sure that you got it. Also, don't waste your money on an additional injector controller, which is also obsolete.

i don't know about that, only the BNR stage 4 seems to be appropriately priced as the turbine wheel is upgraded. the smaller hybrids he builds are a bit pricey for what you get considering they are mainly just slapped together with Garrett parts which generally run about $200, $100 for the rebuild kit, wastegate ported which should cost no more than about $100, modify the wastegate arm to be adjustable $45 plus labor to rebuild the turbo.

while it does require a new manifold and wastegate, cost for cost of the turbo itself the hybrids from BNR closely borderline on much better designed ball bearing turbos these days. a GT35R is ~$1k, spools much faster and pushes about 25-30% more air than even the highest quality hybrid.

hybrids are a stepping stone to a better turbo, i just really wasn't too impressed with the lag created by the restrictive hotside.

I am sure it would be much cheaper to do the work yourself if you have the time and ability, but it is a pretty good deal for those of us who don't. So far I have not found any local turbo shops that perform the same work at a better price. Please post the contact information for any shop that offers a better deal.

I agree that a full turbo replacement is a better option at the high end of the scale, but you are looking at twice the price for the full conversion that you listed. I can see where budget drag racers would prefer the hybrid.

i'm not sure if Brian uses used parts or not but i have tossed together a few T04B hybrids from good used compressor parts with the listed work minus adjustable actuator arm for ~$500.

I will definitely go with the Rtek, although I should probably go with the 1.8 or 2.1 considering my power goals with the hybrid turbo setup. I like the hybrid turbos better because of the price and simplicity of bolting into my existing stock turbo setup. I am thinking of 850cc injectors for both the primaries and secondaries along with an upgraded fuel pump.

Karack, what is that turbo comparible to in terms of performance and extras? Stage 1 2 3 or 4? I may be interested in that turbo.

comparable to BNR stage 2. there is no set standard for what a "stage" refers to so just using it for comparison, i just don't clip the wheels.

clipping increases top end potential at the cost of spool, these 'imbalanced' turbos(referring to the aspect ratio of cold side to hot side) already suffer from slow spooling.

Will you accept my old turbo as a core?

Clark13b

Are the s5 series turbos or s4? I think the s5 is a better turbo design.

RotaryEvolution

core depends on the condition of the core being provided. basically the turbine wheel, exhaust housing and CHRA have to be in good reusable condition. i don't care how mangled the cold side compressor parts are though.

S4 has an inferior wastegate port design but it can be upgraded with a larger flapper arm. the S5 turbo is a better design and easy to switch over to but requires the manifold to the block as well as the turbo since they are not directly interchangable.

S5 all the way. Even before porting the S5 wastegate flows decently.

I'm piecing together a hybrid myself, I'm pretty decided on a 60-1 comp wheel undecided on whether to clip the turbine wheel or not

Clark13b

Do you supply manifolds, if so will you accept mine as a core. If not do you know where I can get a used one? Thank you
