Hello everyone,

Im wanting some advise about purchasing a hybrid turbo. First off, my end goal for my 87Tii is 300hp to the wheels. Ive got a good foundation set with the following

Microtech
1600 secondarys (overkill but they were cheap.)
Front mount IC
Koyo radiator
No Cats
And a mild port job coming soon.
Along with fuel upgrades.

What I was looking to do is Get a S5 manifold and a S5 hybrid turbo. SO my question is what should I look for, that will help me reach my goal, and stay somewhat reliable.

 

t04b housing with an h-trim wheel.

300 is pushing the stock turbine pretty hard. it's achievable, but a clipped turbine would be better.

 

you're going to spend/ have already spent big money on stand alone, new rad, etc... and you want to get a hybrid? boooooooo!!!!!!

go with a nice Master Power 60-1


but if you must, a hybrid can get you your power goal...

 

why bother with a bigger turbo and the lag that goes with it if the goal is only 300?

 

300 to the ground, what does that qualqulate at the crank?

I know the goal is not very big. Im just building a fun reliable car. Its not going to be a street monster or anything. Ive searched and found a few for sale on the forum, but most of them dont have spec, and all this stage1 stage2 stage3, means nothing to me. I want specs!

 

Has anyone bought this turbo upgrage?

I have the BNR stage 3 (suppose to be 350rwhp) and love it, I cannot see going really any bigger with my supporting mods. Plus I am probably pushing the car about as far as it can go on pump gas 92 Octane.

 

Hows the responce? Is it really lag-e?

 

nope, i have one as well and i'm breaking in my motor and trying to stay out of boost and never take my car above 4k but i can't help getting into boost some times because it starts spooling at 2.5-3k.

 

lag is all based on the manifold and turbine you choose. i don't know what you think is fast spooling, but alot of hybrids don't make full boost until or after 4k rpms thanks to that clipped *** turbine wheel. i do agree tho, that if money is an issue then a hybrid will get the job done simply enough. i was just commenting on the fact that it looked like he wasn't going hybrid because of it's cost efficiency due to his other mods. if that was the case, then a true 60-1 would yield alot more power at equal boost and spool up just as fast, espically with a proper exhaust manifold. and it's a turbo that would only get better if you ever decided to port the motor down the road. 400rwhp at 15psi would be easy. everyone says their goal is blah and blah, but we all know that if you could get more power reliably then your going to go for it. why stop at 300? ahahaha

 

I made 305rwhp with about the same mods

 

a 60-1 would make more power at higher boost levels, but i've seen them make very similar numbers to the hybrids at ~10ish psi and below. i made 301whp with a super h hybrid @ 9psi, and 296 with a 60-1, .84 p-trim @ 8psi. not a lot of difference at low boost levels, but obviously monumental difference at higher boost. the hybrid i had on my fc back in the day couldn't produce enough boost to keep up with how much the motor could eat.

a full 60-1 single with all the stuff to make it work is an easy $1500. and that's if you bargain shop. the hybrid is more like $400-450ish. so obviously no sense in wasting money if the power goal doesn't necessitate a larger turbo. i do agree with you about leaving room to grow, but to each his own.



RotaryX
i haven't used that exact turbo before, but you can get something very very similar (if not identical) for about half the price...maybe a bit more. i'm not trying to bash bnr. brian does some outstanding work, it's just a bit costly.. i've made 410+whp with a stage 3 1/2 on a cosmo engine.

the 3 1/2 is just my nickname for what brian built for a friend of mine. s4 hot side, bored out for a p-trim wheel, 60-1 compressor, (basically a stage 3 so far), but since it was a cosmo engine, there was enough room to upgrade the compressor housing from a b to an e.

something like that, or a normal stage 3 might be a good compromise. about half the cost as the "real" 60-1, but most of the performance.

 

My ported TB came from Guitar Junkie too. My hybrid turbo came from rotorsports racing second hand.

15 psi

 

Theres obviously a big price difference between a full 60-1 and a hybrid. Wich brings me to a question of reliability. Whats going to be better on the motor, and will a aftermarket setup last substantially longer.

Thanks for all the info everyone

 

oh damn, i didn't realize hybrids were that cheap. i thought the 60 trims were going for around 700 - 800 still sorry about that.

 

Yeah, BNR wants around $700-800 with you providing the core. That doesn't include the shipping ($50-100).

 

just check out mjturboshop.net

the guys are very easy to work with, and great prices.
