Is this what the seller says it is? T04H trim on the stock S4 hotside with a ported wastegate.

Thanks

 

Ehhh...Id pass on that one.Its definately a S4,which is enough reason to pass.
The cold side looks stock,which makes me wonder why he thinks its a hybrid.Could possibly have a bigger wheel in a machined, stock compressor housing.

The stock T-18 has a decent sized hotside,roughly a T4.The compressor is where it needs more volume,which is why most T18 hybrids run a stock hotside and a TO4 compressor.....you now essencially have a full T4 turbo....kinda.
If you dont port the hell out of the wastegate and/or clip the turbine,the hotside will not flow enough out to match the bigger compressor.The S4's super small,single wastegate hole makes it an inferior candidate for hybridizing,compared to the larger A/R and dual wastegate holes of the S5 T18.Not to mention the S4's crappy exhaust manifold design.....

 

That's why I got an S5 Turbo LOL

 

It's a TO4-H trim on the stock S4 hotside. Purchased from fc3spro.com.. Just got the info.. People say the S4 turbo design sux but the guy down the street dyned 402 RWHP on a BNR S4 turbo. Let's see some S5 #'s to beat that.. Just ask Brian @ BNR about it..

 

yea it's a hybrid, but not much of one. stock cover means they could only go so big on the wheel, but nonetheless better than stock. i personally like the s4 turbo's.

 

I agree after my freind got his dynoed I strongly believe the S4 will kick some butt also.. Brian does great work with them.. He suggested the S4 turbo over the S5 for his car..

 

Why?The center and compressors are the same on both,the S5 just adressed the S4 weakness,which were hot side flow and control.
The S4 manifold is barely a step above a stock N/A manifold,and the wastegate is tiny.Even when ported out,it still only draws from one runner.

Im not doubting that he did make 400+HP,but thats A LOT more power than anyone has ever claimed from a hybrid,S4 or S5.Maybe he installed an external wastgate,its been done before.
And if you have the $$ to make a 400+HP rotary,why would you run such a cheap,wimpy turbo hotside.....no offense to anyone looking at a hybrid,I run one myself.Its just that if you have the money and means,there are WAY,WAY better turbo choices out there.

Recently, someone claimed something like that over on TeamFC3S and it was very hotly contested.

 

I agree.. he spent like 900.00 on it i believe. The owner wanted the most power Brian could make from it and it cost a bit. Guitar junkie (Dave) built the car for him and tuned it. I gues it depends on what you want. I'm doing a TII swap and was going to use a hybrid but decided I can't get the power i want so i'm spending alot more $ and going with a GT3540RS..T04 version from Aspec Tuning

 

I'm going to say that the second gen section would know more about S4 and S5 turbos than the first gen seciton would.

Ergo, it gets moved over there

Here is a pic of my hybrid. Got it from Rotaryshack.com


"hybrid turbo upgrade" for turbo 2 rx7's .. its made by turbonetics with all "tuff turbo" options which makes it much more durable than the competitors hybrids... the turbo 2 core gets a 60 mm compressor wheel , t4 housing and custom back plate to mate the t4 components to you existing mazda center section/exhaust housing!

 

Looks like a similar compressor wheel to my old 'TO4B' wheel'd hybrid. (sleeperfc's as well )

Probably good for 300+whp if you have the right supporting mods.

 

Definitaly!!!!!!!

 

definately a hybrid. i have a s4 h-trim hybrid too, and stock s4 and that comp hosuing inlet looks pretty thin.
ive heard that the h-trim wheel doesnt lose a whole lot vs the full comp housing and same wheel.
i need to hog out, backcut, and weld on a new flapper for my wastegate.
i have a very nice crackless s4 turbo manifold, but am thinking maybe get a SS autochrome and ceramic coat it when i do the hotside, and downpipe. i planned on doing the original s4 turbo manifold but that ss-autochrome might not be bad.....have a welder look at the welds, but that might risk warping it. im sure a good ceramic coating inside and out would keep it together.......maybe

you can get the wastegate out to like 30 or 34mm by welding on a new flapper, w/ backcutting theyre supposed to be pretty damn good....

 

I would like to ceramic coat my hotside as well.

 

haha, I was talking about the original posters turbo.

But holy crap! That is a BEAUTIFUL engine you've got...

 

i want to do either hpc extreme or something a friend of mine has worked with, very expensive


my friends is a bit cheaper i think.

 

Thank you!

that turbo i sold you was a s4... and the WG was ported huge. I never ever had a problem with creep. Did it creep on you?



sooo to the other guy bashing s4 turbos:

The s4 turbo WG can be ported pretty damn big, just have to weld on a new flapper door to cover the hole. also the a/r of the s4 is larger is it not? im pretty sure it is... its a 1.0, but i dont reember the s5 a/r number off hand. Just that its a touch smaller.




bigger a/r or not... its still a restriction and should be swapped for a p trim t4 turbo asap.

 

i thought i heard s4 was .80 or .88 A/R and s5 was 1.0

never really found out for sure.

 

Word on the s4. It worked out great as soon as I got my *other* issues sorted out, lol. At 15psi on a street-ported, bolt-on TII, it was FAST...

I never had any issues with creep. Aside from doing the WG actuator rod 'mod'... Which turned out to be completely unnecessary and (actually) was the reason I blew my last motor...

I'll give the s5 turbo's the benefit of the doubt, but still, there's no reason to discount the s4's... The TS flapper-door can't be THAT big of a restriction.

 

That's interesting, cause...

I
DON'T
SELL
TURBOS

WTF???

lol, I was wondering the same thing. I was thinking maybe i just didn't see that section of your website and i missed all the threads where you talked about your hybrid turboes you sell, haha.

 

that is definitely not a stock turbo pictured in the original post, if you look at the inlet port walls wrong they might just break off they are ported way too thin..

and why is it so hard to believe a hybrid can push 400HP to wheels or for that matter that an S4 hybrid couldn't?

pull your head outta your ***, people that can't make the power just don't know what they're doing when it comes to tuning their mods.
