My Engine just blew and I get to replace it and the turbos with a new ones. It is all covered under warranty! I can get a worked engine as long as it is equal to or less than the cost of a factory engine and turbos. If you could please list (in order) the mods you would buy the new engine and turbos with and if possible where you would get it from.
For example:
Street port?
Apex seals?
High flow twin turbos?
KD rotary?
Pettit Racing?

I need to pick my setup very soon and I do not want to just throw a stock engine in. BTW if I was to street port and buy High flow turbos would I have to upgrade my computer?

I would love to get a street port... as far as apex seals I am not sure which would be better. Go for as much as you are able to.

Not sure if you have to upgrade the computer but you should look into that soon. It was one of my best mods.

before you upgrade to 3mm like i have, you might want to look into the new 2mm compressed graphite seals .there a big hit in japan and a couple kids that came into my shop have requested them. but you have to be careful with them, usually when they blow they almost always ruin the rotor housing because there so hard. if your gonna rebuild and do a street port make sure you have a "friend" at an emissions place.

I'm not lookng to ever replace this future motor so I need hear ideas about durability when it comes to Apex seals. What do the different apex seals do differently Do they just keep better compression or are they more resistent? Having it inspected is NO problem. My thoughts were to buy a street ported motor with high flow twin turbos. Would I need a computer for this? I have heard about better O-rings, silicone water jacket seals and motors that come with the silicone hose rats nest. I know there are many other mods out there so I'm wondering if you guys cold help with suggestions. If I have to prioritize what things should come first? I am only looking to spend the same amount as the factory equipment would cost (which is usually the most expensive stuff). Remember that is all covered under warranty.

You should give KD Rotary a call since they're the closest big tuner to you. From what I've read, 3mm apex seals are not worth it unless the rotors are too worn to keep using 2mm seals. Apparently the 2mm Hurley seals are good though. You should read about the pros and cons of streetporting a motor (more high-end power but lopey idle, poor emissions, less low-end power). I believe that KD can do reliability mods to their rebuilds, such as improved cooling and oiling. Get whatever can be covered by the warranty.

BTW, if you do get a streetport and upgraded twins, you will definitely need an aftermarket ecu and probably upgraded fuel system.

Go to KD, they will tell you what you need/don't need and won't screw you around. I've heard alot of great stories about the Hurley 2-piece 2mm seals. Make sure you get a full hose job while it's being rebuilt, won't cost that much more, probably just the cost of the hose. Replace all check valves too.

High flow twins will cost you big time, don't do the streetport if you're worried about emmisions, maybe a mild port won't hurt.

If you want it to last and be done right, you will have to pay some out-of-pocket that the warranty won't cover.

I cant get it to any shop other than the one it is at right now. I brought it to the shop I did because they are great with the 3rd gen. I have no problems with getting my car inspected because of my mechanic friends. I can get the high flow tiwns for less than the factory ones and I've heard great things about them. Some people say 3m Apex seals a lot of others say Hurley 2mm seals and almost everyone has said street port. The numbers that I have gathered from Pettit are:

$3200 streetported motor (3mm) + $3500 BRAND NEW highflow twins = $6,700

$3,200 streetported motor (3mm) + $2400 REBUILT highflow twins = $5,600

$2,200 stock motor + $3,500 BRAND NEW highflow twins = $5,700

I believe that the stock motor is $2,200 and the stock twins are $3,900 = $6,100 (hopefully this is what I will have available)
So either I spend $600 or have a cushion of either $400 or $500
obviously this doesn't include core or shipping charges. It aso doesn't include silicone hoses.

See if you can give them some money out of pocket if you run out of warranty money. That way you can still get more mods while your engine is apart. Also check out KDs site so you can see the mods they do and ask the shop it is at now if they can do the same.

New standard twins are $2700, but I'm sure you can get them for less from Mazdacomp. Depending on what your spending limit is, you can get Ianetti ceramic apex seals, these are supposed to be the best out there but cost something like $1200 for the entire set. The advantage of cermamic is light weight, which means better low rpm sealing, and superior wear and friction qualities. The downside is if they bust they shatter and take out the rotor housings with them. However don't detonate and they should last a long time. If I had a big spending limit I'd just get a quality rebuild from KD using all new parts plus silicone O-rings, Ianetti seals, and ported oil/coolant passages.

KDR builds a good motor, but do yourself a favor and don't buy a re-man. Buy brand new rotors and housings from Mazdacomp, then have Dave port the motor, install the Hurley double spring 2mm race seals (all he uses) and put it togeather for ya. You'll be lovin life.
As for you turbo's, have Dave look at em. If he deems necessary he'll rebuld them and port them as well, or just replace them too. Let him be the judge on the turbos.

What are compressed graphite apex seals? Does anyone here use them? Has anyone heard about them? Very interested, info please!

artguy

get the streetport....its a MUST if you do the rebuild...you will thank us later.

get the power fc or the haltech...period

get your intercooler

get your downpipe and intake



do as much as you can while it is all out...injectors..fuel pump etc would be smart too.

good luck


do the downpipe, ecu, and intake at the very minimum if you do the streetport....those mods are great to start with (and the IC)...you can run a bit more boost....your car will wake up like the great cornholio on cappucino compared to what you run now.

without those mods your streetport will not be a huge gain....you need more fuel with the streetport..as well as more airflow to get full benefits...and its totallllly worth it.

J, did you get your car dyno tuned yet??? Can't wait to see the results.

Yeah, Hurley 2mm race seals are the only way to go. Also be sure to get it EXHAUST PORTED. Especially if you're going single, exhaust porting is more important in HP than street porting.

Just ask Dragon and Igy who kept winning races
