couple questions regarding Singleturbo conversions:

has anyone ever used a SMIC with a SINGLE TURBO??
and if SO, can you post a picture of the SET UP?

To go single turbo:
Buy TURBO kit.
upgrade primary and secondary injectors 850/1600cc
add upgrade Fuel rail.
Add Coilovers..
Add FMIC??
and a good turn

Am I missing anything?

XSTransAm

fuel pump and regulator and a ems

I dont think coilovers are a needed replacemnt for a single turbo setup

and yes its possible to use a smic with a single setup.

SlingShotRX7

Oh I guess I should list my mods:

DP, MP, CB
HKS intake
Greedy SMIC
HKS Twin powerpak
Greedy Pulleys
Apex PFC w/ Commander

Thinking of going SINGLE..

So to go single I can reuse everything except for the DP, right? Just wondering how much more I need,
Besides the Turbo Kit.

Anyone got a PIC of SINGLE Turbo with SMIC??

SlingShotRX7

Oops I forgot, i got a upgraded Nippon Denso (suprapump) already.

Of course. I hear the ASP SMIC works perfectly with the A-Spec GT35/40. Don't forget a good exhaust. Why spend all that loot on a nice turbo when a restrictive exhaust will keep you from quick spool-up?

Gordon Monson ran a SMIC for YEARS on his FD. Search his name and I'm sure you'll find something on it here.. His car was also featured in SCC magazine.. I forget when though.. Car has been sold since, but that's irrelevant.

I've run a Pettit medium intercooler and now run a CWC intercooler... both stock mounts with my APEXi RX6 single.

SlingShotRX7

Hmmmm I seee.

anyone use a GREDDY SMIC?? with SINGLE turbo??

Pettit and M2(asp) medium/large have Different intake
and outtake unlike the GREDDY... Where the in/out are
like vertical, instead of horizontal. Thats Why I wanna
see how someone with a Greedy SMIC set up with a SINGLE.

Thanks for your patience, I am SINGLE turbo NEWBIE

mad_7tist

/\ isnt the greddy just a glorified stocker with steel end tanks?

Hamza734

Nah, Greddy's MUCH bigger then stock. Only problem is, the fitment on ducts, which is supposed to be ****. I think the you have the same problem with the Pettit. I did a lot of research into SMIC's and I think the ASP/M2 is the best hands down. There's a lot of detailed info on this page:

Also, I think they'll group buy on the ASP intercoolers soon.

anyone??

The IC is all about heat soak, the bigger / more efficient the IC the more it is able to soak up heat generated by compressing air.

There are racers with rotary powered sand rails, and other turbo charged rotaries that have no IC, this is do-able with two things in mind, When Running, you'll get one real good run in, and then performance will drop, more and more. Also with that in mind the intake temp will rise, so make sure you have high enough octane gas to avoid pre-detonation.
Given those two "Known" Factors, you can run with a tiny IC like the stocker or none at all, but chances are with a street driven car, that you want concistent performance, and you don't want to handicap your turbo by running 10 Psi or (insert number here), on it since above that you have to buy race gas, or get a bigger IC....

Bottom Line, It's all doable, it's just a tradeoff.. less IC = Less Cooling capability wich will limit your performance...

Sean you can use a smic with a single. Its actually the way that most road coarse guys set their cars up. Front mounts are more of a drag race thing. Paul Winters Fd is set up with a PFS large race IC and a t-78. At least it was last year. I do belive that your greddy is to small though. You can do the smic I would just get a bigger one if that is what you want to do. I would not use your IC with a single turbo. Which turbo kit are you getting?

DHALL

Seeing as you live close and I just posted about your motor, I will say the same thing. Get a hold of Dee of Reactive Racing if you are going single. Check out his new R85 single turbo kit, that is what I am getting.

You're also going to need a BOV and boost controller.

I have a SR IC that is similar to the Greddy in size. Same vertical pipe couplings as the stocker. It seems to work fine and held temps under 60C during multiple dyno pulls at 15 psi with my t04e. Normal driving intake temps are from 35-60.

I'll eventually get a larger IC, but this works just fine for now. I think I have a pic at home if you want to pm me your email address.

SlingShotRX7

Sweet..

Thanks for the LINK..
Thats exactly what I was looking for
so my SMIC can be used with a Single turbo.
In that LINK, what is that metal canister next
to the Intercooler??

Why would I need a BOV??
I thought the STOCK BOV was probably the best.
Boostcontroller like a AVC-R?? Doesn't my PFC
control boost well u nder 15psi??

Reason i am askign so much is because, wehen I get my
new motor or rebuild, I most likely gonna need new
Turbos, so I fi gure, HELL Might as well go SINGLE turbo.

Thanks again..

huffner

Sean, your motor has 130K plus miles on it and it is the original motor. Melt it down or turn it into a boat anchor. Get a fresh reman and port it and go single. You need a bigger SMIC and a BOV and a Boost controller. You cant be cheap on your ride you got enough out of that most never get so consider yourself lucky. Spend the bucks and you will be much happier in the long run.

Hamza734

I agree with Huffner, a new motor is a MUST. However, you should consider rebuilding while it still runs. If you let it go until it pops, youi'll probably be looking at a junked rotor housing and possibly even a blown turbo. Pull the motor down and rebuild it with some quality apex seals, and perhaps a port job. It'll be a LOT cheaper then a reman.

As for the BOV, the stock one is MORE THAN adequete. Go to any race track and look at a seasoned racers car. See a massive J-spec BOV? Hell no. In fact, I often see pros come up to a newbie and smile when they see the nice shiny BOV under the hood....maybe it protects the turbo but I've ran piston engined cars with no BOV (not even stock!) and never had a problem. Furthermore, I've yet to see a single instance when a car with a BOV ran measurably faster then a car without a BOV. If you want the sound just remove the recirculation fitting from the stock valve and put on a breather filter. It'll make all the sound in the world.

As for the boost controllers, I'd stay away from the Apex'i. Too expensive and a nightmare to use. Do a search on this forum and you'll find a lot of people who've had problems with the AVC-R. Go with a Greddy Profec B Spec 02 or a Blitz SBC-ID. They cost about the same and both will get the job done.

SlingShotRX7

Thanks guys...

in the works for a Greddy T78.

OK as of NOW... to go single turubo.

I need a New (bigger IC) front or Stock mount
Bigger injectors, primaries and secondaries
850/1600, NEW fuel rail. Boost controller.

WHEW..

On top of a NEW MOTOR...

Hamza734

I'd stay away from a T78...that's a BIG turbo. You'll make a lot of power, but you'll pay the price in turbo lag and when the turbo does produce boost, it'll hit like a sledge-hammer. I think either GT35/40 or the XS T04 would be better....and their cheaper to boot.

phlanigan

Don't forget the new clutch if you pick a large turbo.

If you opt to use a stock BOV, you're going to have to rig up a fitting for it. It is also loud as hell if you don't muffle it, particularly at high boost levels. I thought it was easier just to get an aftermarket one for ease of installation and noise reduction. Doesn't hurt that it is nice and shiny...

Your selection of a BOV or deciding whether to run one at all will have absolutely no impact on power output, assuming no leaks.

radkins

I run a to4s with M2 Med smic. Works great.

Hamza734

All the more reason to go with the XS Engineering kits....they even include an Apex'i BOV! You might want to have a look at this page:

You can overlay the dyno sheets of numerous different turbo setups.
