what turbo modifacation will give me 350hp????
#26
My turbo can probably push 300rwhp+ if tuned very well and I had a standalone ECU. With my s-afc I don't expect to break 300rwhp, but I hope to come close to it.
I have the stock fuel rails with 4 720cc injectors and a walbro 255lph pump.

350bhp at the flywheel or 350hp to the wheels?
350hp to the wheels is over 400bhp at the flywheel.
I don't usually like to push anything using the stock center housing with the carbon bearing over 14psi - I've had bad luck keeping this carbon bearing from puking oil over 15psi. Others will argue that you can run more boost.
Compressor upgrades or "hybrids" can get you to 350RWhp (at 14psi), but it's at the extreme edge of it's capabilities. A 60-1 or H-trim would probably get you those numbers.
A more "safer" method is to go with a full turbo uprade, but we're talking bucks to properly do this conversion.
$1,000 turbo
$1,000 FMIC
$1,000 fuel pump, fuel injectors, etc. (overly estimated)
$1,000 turbo manifold, piping + miscellaneous

o.k. forget the s-afc I'm going with the microtech
I have 1000cc for secondries and a FMIC
get a 60-1 conversion on my turbo
now wastegate - external or port whats on?
"ryde or die"
have you got a stronger spring in your waste gate?

Jeyjey: Start talking with your local turbo shops about options, learn to read a compressor map and look at other brands of turbo's besides Garret. A decent intercooler for 300-350rwhp can be found for under a grand easy, I found one brand new for $690CDN and it should do 400rwhp
I would shy away from the hybrid turbo. Start looking for a "real" turbo setup, you'll be much happier in the end, plus it opens up more options, if in the future tou find you want more than 300rwhp.

I have the stock wastegate ported all to hell and a much larger flapper door welded on.

That is true. But when your stock turbo goes and you have limited funds and you find a nice upgrade for like $400, its worth it to me. Plus I can always sell mine. Not like its value is going down really. Has like 2000 miles on it. But there is more to getting a different turbo. You need a manifold, DP, wastegate, and enough fuel, plus the turbo.

The problem I have is there are less than 100 T2's in the U.K. and everything is so expensive .
has the place that sells the T51 switzer got a website ?
thanks jeyjey

any reputable turbo shop should sell switzer S300, is the model that is equivalent to the T51! and the price of turbo's should not affect you specifically as there are many turbos! You shop seems to be getting a good deal off of you! as my turbo was about as bigg as you could get with the stock housing... mine was even machined!
I would shop arround alot more maybe even give some places a call in the US to get one. I might be even cheaper to pay for the shipping that it is to get one from your local turbo shop!

I'm looking to do the same right now, but 300 rwhp is all I want. I've already got a walbro pump, what kind of turbo should I be looking at? Spool is more important than power as long as I'm in the 300 range. (I might actually have upgraded injectors too, but I'm not sure how I can find out...)

you can do 300rwhp with a hyrbid turbo but it will most likely be just about as costly as a good full T04 turbo is would be worth the money to spend on doing the turbo righ the first time!
the thing about going full t04 is you are looking at;
fuel management (of some sort most likely standalone)
Good FMIC,
External WG,
Good BOV,
Street port (which means engine rebuild),
custom DP,
Turbo manifold, (goes from block to turbo)
the cost is extra but well worth it IMHO.

Will the factory turbo manifold work with the T04? I saw one of those for like $500 and thought about getting it. And why do you keep pushing to street port? Is there a reliability reason to get it done?

Nope you need a new manifold. And porting really helps with turbo rotaries is why he is pushing that.

I am not pushing street port because of reliability reasons. It is because when mazda first desinged this car the ports were made a little bit smaller for "emitions" reasons. Now think of this, if you want to add more HP you need to add more air/fuel right? that is in essence what the turbo is doing adding more air due to compression.
Well take a straw and blow through it when it is perfectly straight. Easily done right?
Now take that straw and bend it about 30 degrees so there is a kink in it and try blowing through it again. More difficult right?
Now think of the stock port on the engine being the straw being bent, and think of the street ported engine the straight wide open straw.
It is simply more difficult to reach 350hp with the stock port (can be done) just more difficult.
Another added benefit from the street port is when you port and engine properly you do the intake as well as the exhaust. So if the exhaust can leave the engine faster due to the larger ports then there will be more flow of exhaust gases for the turbo allowing it to boost higher and quicker.
hope that helps.

I already understood the street port but I wasn't sure if there was another reason beyond power gains. Not sure If I'm ready to devote my engine to being opened up again. Only got like 10K miles on the current rebuild.

You can rip it apart and port it and you will probably only have to replace a few gaskets, the seals should all be fine. It's an option.
As I've found out there's alot to do, to get the car in the 300rwhp range.

Plus the time as well. My car has not run under my ownership longer than it has run, that's sad to think about. I've had a few set backs, but I'll keep pluggin away and it will all be worth it in the end.
