From what I can gather, any hx40 is going to be perfect for you.. the stock hx40 exhaust housings are either 17 or 18cm, which is quite large, 1.1 a/r ish on a gas piston motor.... and just right on a rotor motor.

as far as HP support goes, the hx40 compressor options are fairly flexible... and well over the 300hp that setup can handle.

Problem: Bilstein says to not put on lowered cars

Solution: Make the top hats taller. Dropping the car 2 inches? Make the top hats 2 inches taller.

Do what, -------?

Dropping the car about 4-4.5" all the way around. Without a kit, it will sit about 1.5-2" off the ground. I'll raise it up when i purchase aero. I want my ---- DUMPED. I already bought them anyway. They're sitting on my floor in my room and i just got done sessioning on them with a wire brush to get rid of the surface rust..... Threads are perfect, top hat pillowballs could use a greasing. Other than that, they're straight.


Holset hx40 it is. If i dont like it, i'll swap it out for something else. I've had several votes. Kain is on the same page as jd, trying to make me eat top ramen and easy mac for a couple of months...... BNR stage 4 turbo is $825 with a stock core and that's what he recommended. For that price, a master power 35r looks more appealing. Called rotorsports racing and they said i'd be fine. I'm trying to get ahold of my tuner but he's swamped with ----. Everyone got their tax return and is spending money..... Jakob, the guy i bought my coilovers from is running a bnr turbo. He's got a stock T2 engine he's putting in his car today though. He has no idea what i should do as far as turboing my six port but gave me a few screen names to hit up if i have any questions. He did say my idea to use a T2 ecu, map, afm with t2 primaries and 750cc-ish secondaries should work fine. They'll be a few bugs to work out at first but that's a rotary for ya. He also agreed that i'd need to dowel my block and switch to an s4 rear housing if i plan on making 450 or more. A friend of his ended up completely destroying a motor. It was a 4 port but wasn't doweled. Just a large street port/extended port. He was making around 500hp.

Wtf is aero? You still might want to make the tophats taller.. I don't think dumping any kind of shock like you're planning on doing is healthy. If not suit yourself.

aero

I'm sorry but I'm not for sale.... lol

$200 for an hour of your time! come on!!!!


Seriously, had i known a rotary would kill a holset, i wouldn't have posted.

If you're on such a tight budget, I'd suggest you ditch the RX-7.

Anyways if you really are, a Holset is a great choice. Tough turbos, can be purchased cheap with relatively low milage, and can really pump out the power - relative to a turbo Honda's needs at least. The 6-blade HX-40 wheel can do around 68 lb/min, which is more than enough for pump gas - but as you seem to think rotaries are some completely different magical solution, all bets are off. Power pulses be damned, you still need X amount of air to create Y amount of power, so in that respect rotaries aren't different from any other gasoline engine.

If your power goal is 300-450whp, you don't need anything bigger than even an HX-35. An HX-40 has the ***** to make over 600whp with the right motor.

In my experience a hybrid 40/35 can make over 600whp, and a full hx40 is a lot closer to 700whp.
