i blew my twins today but not in the good way. lol. any ways the ht 12's (stock turbos) are out of commission, so the ? is what to do, what type of setup should i do?

t3 single?
bigger twins?
t3t4 single?
t04 single?
other?

just give me some sugestions and what all i will need to make it work

 

Define "blown."

Oil seepage out of the shells?

That isn't necessarily blown.

 

What caused the twins to go out? Higher boost? How many miles are on them?

 

Go single or get BNR twins.

 

Depends on how much money you are willing to spend.

 

Well I was at about 7k -7.5k rpms when i heard a pop and then a ZZZzzz sound then i looked in my mirror and saw a smoke screen that would make James Bond feel like a *****. (i coverd the road) the smoke was white so i pulled over and shut it off thinking apex seal i called a friend to pull me to his house a few blocks away and then called another friend who owns a performace shop and knows alot about my wankel and why its shooting white **** i mean smoke lol he says most likely one or both turbos are fucked. when you start the car it runs smooth but shoots a ton of smoke so im planning on making the best out of the situation by making it faster i just dont know how i want to go about it yet so im looking for ideas

 

the twins have 80,000 on them

 

so what turbo setup should i use

 

my first set of twins did that. the secondary went out and caused a ton of oil to come out my exhaust. i thought it was a blown motor at first. the nut on the end of the shaft fell off either after or before. not too sure.

there's too many setups out there to just pick. you'll have to decide what the main purpose of the car is. i have a t78 and love it

 

a single setup is going to cost you a ton

Not many people are capable of putting a successful single setup together. I'd just get another set of used twins with low miles. Easy fix.

 

T04Z

 

I'd just get another set of stock twins, if not maybe find a single kit that soemone boght and never installed, you might be able to get it cheap.

 

whats so hard about doing a single turbo setup? The guy i had look at my car has a 2nd gen with a ford v8 supercharger on it and a 3rd gen with a t3t4 and both run great and fast as hell. he said i would have to block off an oil line for the secondary turbo and get a different turbo manifold and intercooler with all hard pipes, and a few other things.

whats the psi running on that t78 and what else did you have to get to make it work? injectors ect.

I would like a car that has mad top end but yet still can hold it own on the stip and corners thats why i was thinking a t04 if ive got enough cash to do it.

 

i dont want to just get the stock turbos back on for 2 reasons.

1. not enough cfm (slower fd)
2. bad turbos that blow up after 30,000 or so

 

Take the turbos off and open them up. Then you'll know for sure what you're looking at.

Blown outer turbo o-rings/seals are not worth the expense of pouring thousands into a single setup - especially if all of the blades are fine and the shaft is still true.

 

i run 16psi on my t78 on pump gas. i will tell you that to put a successful single turbo kit together and make it somewhat reliable, it will cost anywhere from $7k-$10k after you piece everything together. you'll need the turbo kit, fuel system, block off plates, engine management, intercooler, plus the motor must be in good shape or it's going to be pointless

 

7-10k with or with out a new motor

 

that guy who looked at my car said with a t3t4 setup wouldnt need new injectors or any major add ons
does that sound right?

 

the stock injectors max out around 320-340whp. a fuel system will run around $800-1000, a turbo kit $2000-4000, intercooler $1000-1500, block of plates are only around $60-70, and a PFC will be around $1200-1300 with commander. you'll also want the datalogit which runs around $300. also take into consideration that you'll want to upgrade the cooling system. then there are driveline mods that you'll need to make if you plan on drag racing. there's a lot more to it than people see

 

It will be 7k-10k for the stuff mentioned above and it sounds like you can't do it yourself so you can probably add a good slice for labour charges.Also tuning aswell.

 

trust me im not trying to be a dick but it's hard to remember all of the things needed for a single its a lot and if you add labor that could be a ton as well. I know for the custom work Ive done my bill would be well over 3k just for labor. No that doesn't include new motor.

Now if you just want a single setup just to have a single and get rid of the twins then that can be had fairly cheap but you are going to have increased lag and near the same power output as twins at each psi so what's the point.

Here's pretty much just the engine parts I have to support the single. I also am putting all of this on a new engine. Afterwards youll need better tires and to pay for the car to be tuned ~400. I spent about 225 on new gaskets and o rings for the new engine to go in and still need to have intercooler pipes made as well ~ 200. I also still am using the stock radiator which has worked ok. A better one is 300. With the increased power youll need axles and a better differential as well if you track the car or launch hard on the street. See why the twins are worth keeping? Best bang for the buck if you are happy in the 350rwhp range max.

what brand should i go with? what seem to work best for you guys?
and what size? i mean does that t66 or that t78 give you alot of power down low or is it all top end?

 

No single will feel like the twins down low, but let's say 4k and up there a quite a few that would do the trick.

You didn't state a mod list, so if your close to stock, why not put some BNR's on there withe some bolt on's and it will feel like a new car.

It'll be a pretty penny either way.

 

I have:
new motor w/5000k miles
2mm 2pc mazdatrix apex seals
mild street port
hks downpipe
apexi s-afc
apexi intakes
mazdatrix silicone hoses
hooker exhaust
Fludine radiator
trans cooler
its an R1 so its got the 2 oil coolers also
and thats about it i think besides the blown turbos lol

what do you setups spool at? t78 t66 t04 ect.

 

Hows the s-afc working out for you? I hear those suck on our cars. You can get some J-spec twins as replacements. They put out a bit more power than the stock twins. If you have the money to spend on the single conversion and dont mind waiting for the car to be done, go ahead and do it. Just make sure its done correctly or else you'll need a new engine and possibly a new turbo from the apex seal chunks destroying the blades.
