I was thinking about eventually going turbo after I learn much more however I've been keeping 1 eye on ebay for any interesting prospects to buy until I'm ready. I know that the blow through die hards are not going to like this because it looks like a draw through... I dont plan on running more than 10PSI as I'm still stock on my internals.

There some name dropping in the ad that some of you guys may know. Off the bat I would be concerned about the plumbing from the carb to the turbo and again from the turbo to the engine intake... but that may be how this is normally done. I'm sure I'm missing a crap load of things but for all I know you may say this is a good setup or its a flamming piece of doodoo. None the less please help educate me. Thanks.

if i rember correctly its capable of making 400hp

i think thats the rayjay blowthrough setup that came with the pacific avaitor convertiavle 1stgens

im not 100% sure.

seems to be customized with a sidedraft instead of a holly.

That doesn't seem like a bad deal, I might bid on it and snag it out from under you! JK Seriously, there aren't a lot of turbo kits avaliable for 1st gens, especially 12a's. If all the components are in good condition it would just about be worth the starting price. If this guy was running 18psi like he says, he's probably selling the kit due to grenading his engine from detonation. If you decide to get it, you may want to upgrade your ignition system to a CD type box (MSD, Jacobs, etc) and run a boost-sensitive ignition retard to help prevent detonation at higher boost levels. You should also look into fitting a different intake manifold-the one in the pic looks EXTREMELY restrictive. This kit would make a good start for you, though. But don't expect the claimed 400HP, you could more realistically expect around a 30-50% increase at around 5 or 6psi, above that you should run an intercooler and retard timing with the "high" compression ratio (compared to most factory turbocharged engines) of the 12a's rotors. You may want to use an intercooler anyway due to the placement of the turbo with this set-up. The intake manifold and inlet is directly over the turbo so the pressurized air charge would probably be hot enough to promote detonation at lower boost levels. The turbocharged 12a GURUs on here could give you better, more detailed answers than I can, but I'd say go for it if you can afford it. But buy a few more parts before you install it...

Is that a Draw-thru setup
I thought you couldn't run a intercooler on those because the air flowing through the intercooler isn't compressed at all
Ohh well just run water/methenol injection and do some ignition upgrades that would be a pretty cool ride with low boost lag

^^ Agreed. You would most likely have to run water/meth injection because draw-throughs don't respond well to traditional intercoolers because you would be running an air/fuel mixture through the intercooler instead of just air( If placed between the turbo and intake manifold). This leads to problems with the fuel seperating from the air in the intercooler and puddling. Hope this helps.

I have my eye on that as well. I just popped in to put up a post on it and see what the guru's had to say. I don't see a turbo model on it. Is it possibly a s4 or s5?

Sorry, I should have been clearer with that reply. I mentioned changing the intake manifold but didn't mention you'd need to if you were running an intercooler. HIM-it's definately an aftermarket unit (see the external wastegate?). The kit would be worth the cost of the parts, but I'd mix and match with other components for better reliability and more performance with a less restrictive intake and intercooler...

you shouldn't get 400 hp...you are mad to boost more than 12 psi w/o an intercooler...

rx7learner

Thinking of the mix and match concept... Lets say I want to go blow through....Is there any way of buying all the seperate components? I see all of these parts seperately on ebay. Besides the components that bolt onto the intake and the exhaust... what is 12A specific and has to be custom fabricated?

I think these are all parts needed for a turbo setup???

1) An Intake
2) Carb Hat (I have a mikuni)
3) Turbo
4) Exhaust flange
5) Intercooler & pipeing
6) Blow off valve
7) Downpipe (and a shop to do custom exhaust)

What would be great and make it easier for some of us newB turbo interested 12A people is if someone could say the specific parts they have installed in their setup, where they got it, along with what had to be fabed. I would think most every component is manufactured (maybe not for our cars but manufactured none the less).

What I dont want is to settle for something just because its a "kit" when I could have assembled it better.

Read carefully....
He stated that it's "Capable of 400 HP on 18 psi" he didn't state that it makes that much power.... Anything is "capable" of anything until you prove it.
Also, it looks kind of beat up. Look at the piping and wastegate... they look kind of crappy.
Either way good luck on going turbo.

Thats why I was wondering what parts were worth it (ie 12A intake and exhaust for the turbo.) I'm assuming the wastegate is replaceable and the downpipe I can have redone by a custom exhaust shop by me. If i had the option to buy all of the parts new I prolly would... it's just I dont know what has to be custom fabbed or not.

The exhaust manifold has to be custom made, unless you get this kit or luck into finding a JDM 12a turbo piece. You can't use the 13b manifolds due to the 10mm difference or so between the ports. This kit would give you a good head start IF the parts are in good shape and usable. If you're dead-set on a turbo set-up, get this kit and add the needed pieces as you can afford them, but don't run it the way it is. Wait until you have everything together before attempting to install it. From the look of things, you may want to have a professional/shop perform the labor for you.

I see aerosol over nasty condition, and new parts here and their that dont look worn... bolts painted to the metal... im leary

Modified85

Hey learner, hows that 12a I sold you? I think you should consider a conversion to a T2 13b turbo engine because you will have to rebuild the stock 12a motor to get longevity out of a turbo setup. At that point you could have rebuilt a T2 13b that was originally built for a turbo application and will most certainly last longer. Also consider that you will have to spend extra time and money looking for scarce turbo parts for a turbo 12a, and you might have to pay pros to fab up parts that might be more easily availiable for the 13b, ie exhaust manifold etc.. Also I think this kit has recently been sprayed with a cheap can of paint and probably wouldnt look as appealing with out it. They might be hiding its true colors.

thats the type of kit that makes you engine go boom...

nepopolus

you should make your own turbo kit, just find parts people are selling and piece it together. basically the cheapest way to make a turbo kit, and the best because you got all the parts, and you know they fit rather then a ebay part.

boriqua51371

rajay is a good kit but that kit there looks made up. the rajay came with a pipe that fit directly underneath the carb also i came for stock nikky carb . looking at this piece you can see there was some rigging done to it. if you want a rajay set up contact rober at www.rotaryshack.com i saw he had one for sale including turbo. also there are other ways of turboing your 12a for example hks 2nd gen exaust manifold all its needed its to drill the mounting holes 5mm on each hole and and just buy a turbo of your liking and westgate. infact i have one for sale i bought from rotary shack and its not one day used.

http://s39.photobucket.com/albums/e1...xhpics_001.jpg i also have the westgate for it hks 40mm . this would be a bolt on for your app. if you are interested shoot me a pm.

Now that we are on the Ebay turbo subject.

Will this one give me 280-300whp on a 12A blowthrough?
Anyone ever dealt with him?
Crap turbo or not?

Hey Modified85... its still running strong and smooth but I wish I had your setup... Hence the questions. I think I agree with you... Considering the availability of all parts for the 13B turbo... switching out to a 13B would prolly be the best bet in the short and long run. Just hate to switch that 12A out as that baby sings (quick but just not enough umphhh though).

BTW since you have been through the ringer and we could prolly eat lunch off of your engine.. What do you think your shop will charge me if I bring em a 13BT tranny and ecu and asked them to install it... unless they can get a hold of one for a good price.....

I also sent Robert at Rotary Shack an email asking him what he could do for me as a starter turbo project.... Havent heard back yet.

12a turbo setups are pretty easy to piece together
If you want a little boost pick up a good used 13b turbo and manifold
you can get a boost preped nikki and a small intercooler
lock the dizzy
get a wideband to help you tune the thing then you are set to run a little boost for about $1000

That kit looks pretty good and rare as well
the price (so far) is not that bad but it would probably take a little more money to get it all running right

rx7learner

SPERRYsan... I though I couldnt use the 13b manifold on a 12A???

I have a mikuni which I heard is a good carb for boosting already so I'm assuming I wouldnt need a boost preped nikki... just a carb had for my mikuni.

You can, you just have to oval the bolt holes a bit. I would rather fab one, seeing how the exhaust ports will match but not perfectly.

Catatonik

You can use the 13b manifold, you just need to drill the bolt holes outwards a few mm. Its not perfect, but gets the job done.

As for the OP, short answer: no.

Long answer? Nope.
