Here is the engine the turbo is going on => Benson gsr sleeved 83mm, pauter rods, and all the other good stuff. The head will be b16 with skunk2 stage 2 turbo cams, and head is built. I currently have a nuekin ram horn mani with a precision sc6169 ported housing. Im looking for 650+whp. Will this turbo do it or do I need something bigger. Please tell me what I need.

 

The Borg Warner S362 should do the trick for you, but if you're looking more towards the "+" side of things, then i would recommend the S366. I've never really been a huge Precision fan (not that there's anything wrong with them), but those are the turbos i would suggest for your goals

 

What about manifold? Will the ramhorn do the job or will a top mount be needed. Im just shooting for 650+whp but I will be driving this car on the street and maybe take it to the track once.

 

Ramhorn will be more than adequate.

 

Thats what I thought but would it restrict me from the gains of a bigger downpipe?

 

your not running a huge turbo or power level so you will be fine, people have made 800+hp on a log manifold and 3" DP.....

If your worried about your DP size run a 4", most Ramhorn can fit one with a little finesse, if not run 3" to where you can increase to 4" and be done with it.

 

4" should be race application only. For the street, its unnecessary.. Heh, but so is 650+whp.

 

Well I dont plan on running 650+whp everyday. I just want to build it for that just incase I use the car for full race.

 

I need some more options. GT3582R??

 

There are a lot of options that can easily fit this category of power. Instead of just throwing out turbo names and configs, understand about the pros and cons of each FOR YOU.
-Budget?
-turbine inlet Flange? T4 or T3?
-Willing to run coolant lines or no?
-Is there enough room?
-Is top end more important or a shorter powerband?

Anyone can spout out names of turbos and opinions from GT3540S , T67, S366, S362, SC61, etc etc, but it does no good if you don't narrow down your needs other than just power. Everyone here knows someone that has had the above mentioned turbos w/ mixed reviews and experiences of each. Research a few applications, check flanging options as well as budget, and go from there. But it does no good to simply ask for opinions, when this entire forum has this testimony ALL OVER it. Just search a bit more on the forum and in yourself, and you'll find that right answer.

 

Budget = $2000 consisting of turbo and manifold
flange = perferrably a t4
Coolant lines = I'd rather not but if I have to I will
Space = Its an eg hatch with a b18, I can make room. ( but im not looking for some drag set up with the turbo sticking out the front bumper)
I want something to get me over 650 without revving past 9000, perferrably 8500

 

Budget includes the turbocharger only. That will avoid confusion. "Revving" past a certain point for power is a bit moot of a point, since no car "makes" power after a lower rpm level unless it was built as a race-purpose car only.

Since it is a T4, now you want to look at what downpipe flange you want to use. BW v-bands are a bit different than Garrett V-bands on some applications, so you may want to be aware that you may have to cut your downpipe flange to fit. Most Garrett applications (including precision) are 4 bolt applications, so please take that into account.

Do you care what boost level you want over 650whp? under 28psi or over 35psi? This may be determined by the map sensor and management used.

no one knows the cost of the manifold that you may pursue, so as I mentioned earlier, keep the price to the turbocharger itself. Also state if you are using a Top mount or bottom mount manifold, as that may limit or expand your options for fitment. Good BW applications like the S366 like topmounts for topend power, and they can stilll fit in the engine bay, while that same turbo on a "Ramhorn" (god, I hate that word to describe Kooks), may not work for the same application.

The S366 has always been a good choice for the power, price, and options available to get over 650whp w/ less intake air temperatures than even a GT35R.

Here's a few videos of it, both of which were from Speed Trapp (No promotion here, just an example of his available options).

This is a journal bearing turbocharger, believe it or not, w/ great attributes due to its Extended Tip Technology. (Search on H-T for that description). But here is a comparison of the compressor wheels. Same "trim" of 50, BW on the left, Garrett on the right.


Here's a general photo of the turbocharger itself. The cartridge is "shorter" than the Garrett, as well as a bit more on-center than tangental compared to most Garretts of similar size. The exhaust wheel is also a little larger at over 80mm than the standard T67 (either P-trim or stage 5 wheel), so there is more top-end power.





There are several other members using the BW as well as Garrett, so you may want to ask them individually for their personal experiences as opposed to "bumping" the thread all the time to get proper feedback.

 

Okay I believe I have narrowed it down to either a s362 or s366. I would like 700whp. I know both turbos have different exhaust side options. Which one would be best for me? s366 with t4 .83a/r?

 

any help?

 

T4 .83A/R would make the 700whp, you're looking for. It is a divided turbine housing, but you can still run a T4 standard turbine flange. The downpipe is 3.25", so you'll need the special v-band clamp. It is not the same as a garrett.

 

in so i can look later when i have time
