G'day fellas, long time no see.

Well i finally secured the engine ive been looking for (Cosmo 13B TT) should be getting it shipped in a few weeks. (there are some dodgy characters on ebay hey steer well clear of the ones asking to do a wire transfers, and report them to ebay).

Just got some questions for the Gurus;

1. Im swapping it into a 1985 SA22C right hand drive, im pretty sure the twin turbo has to go, due to clearance issues with our RHD steering boxes. any suggestions on a particular single trubine/compressor makeup to make a reliable 350HP?

2. Whats the deal with the stock SA22C gearbox and diff? some people have been telling me its tough enough to withstand that sort of punishment? any suggestions on a good setup?

3. Anyone got a Cosmo 13B in thier SA22C i could have a look at?

I can answer #2 for ya. As long as you are not dumping the clutch everytime you leave a stop light, then your stock setup will be fine. There are guys in PR running SP/BP turbos on stock trans and rear ends.

As for the 1'st question, I think you will get more help in the Turbo section of the forums than here.

You're talking about the 13B-RE engine right? I'm sourcing my parts. for my Cosmo into 1st Gen build now! I havn't gotten the engine yet but I'm curious if you can let me know when you get it in. I'm curious about how the piece mounting into the throttle boddy compares to that of a 3rd Gen RX-7. The piping that leads from the intercooler to the throttle boddy has four screws and i'm wondering if it's the same as on a 3rd Gen.

There are a few threads somewhere in the first Gen area... but i can't find them. If you find them can you let me know too?

I'm planning on putting in a Turbo 2 tranny in mine. However I'm aiming for 450-500 HP.

Good luck on your build!

I have an REW in mine. But there are a few others on this board. Setzup, and Directfreak are a couple of the others.

Also, try asking on http://www.ausrotary.com/ if you haven't already. Lots of guys there that could better answer your question about the clearance for RHD cars.

Which part are you talking about? The elbow? I'm scratching my head because I'm pretty sure mine has 3 studs/nuts.

Setzep and Directfreak helped me a lot with decisions for my swap (13b-RE).

Here's my '84. As for turbos, I recommend a 60-1 as a good performance vs. price choice. I made 420 RWHP with mine at 14 PSI boost. I'm currently in the process of swapping to a GT35R, looking for faster spool.

For the diff you have drums...up grade and get the gsl or the gsl-se setup yo will be so much happier you did...For the gear box run the sa22 that in itself is a hard tranny to find and the gearing is awsome for your setup and will hold up to the power...But like it was said above unless you plan on dumping the clutch at ever single street light it won't last...

For the turbo go with a schwitzner turbo s200 small and will stay make the horse power your looking for and on top of that small enough to fit in your right hand drive set up holla back playa

Thanks guys, very informitive feed-back.

The engine is getting pulled apart and rebuilt with all new internals and street-porting.

I will certainly be posting a piece-by-piece build thread as we go along.

Im looking at a supra gearbox with an adapter plate at the moment if i can fit it, ive also read that there is a Toyota Hilux LSD diff that is suitable for this? anyone know of it?

i am going to run a tII tranny w/my 13bre... this is going in a 84 gsl-se...

in dec. i helped a friend of mine put a 13brew motor together for his 84gs... he used a tII tranny as well and it worked out great... he does plan on putting a grannies speed shop 8.8 rear under the car after he returns from iraq.... but the gsl-se rear end that he transplanted in the car did just fine for the test drives he put it through...lol i don't think it would last to long under those conditions...

The TII tranny is a direct bolt-up to the engine, and it will fit in an FB with some minor mods (do a search). The Supra box has a very good reputation, but I don't know if it's worth the extra effort at the HP level you're targeting.

I went with the TII tranny. Drop-in FTW.

Matt_S3_RX7

Yeah sounds like the TII tranny is the way to go and bolts straight on, and i agree if im not aiming for crazy ammounts of HP then maybe the Supra box is pointless.

My stock SA22C box has had it after 185000kms of abuse.

if your going to go with the turbo TII gear box the only thing you have to change is the tail shaft to a 12a and your int he game...there is no cutting or anything when you drop it into your fb chassis...or the fb tranny tunnle...

Dysfnctnl85

One thing I didn't think about was modifying the gear selector. The shaft needs to be shortened and then you can bolt the tail housing from the 12a trans onto the TII trans. This puts the shifter back in the 12a position.

I'm sorry I forgot all about that -- it's been awhile.

Just checked out this site http://www.atpturbo.com/Merchant2/me...egory_Code=GRT

What Turbine Housing A/R:would you suggest for the GT35R? i havent done the math yet but would like to see where the numbers map in relation to your choice.

Go to the single turbo section and search. This topic is what they live for. There are many posts on this topic. Then, let us (or them) know what you are considering.
