Sorry Guys, I decided to use this as my running parts list. I will add to it, change it, and so on as the project continues. It was originally a PM I sent to another member, and I posted it elsewhere (area 51). I figured it belongs here anyway.


N1XRR wrote on 05-17-02 03:48 PM: Info? I got your stinkin’ Info right here!!.

First, let me tell you, a GSL-SE is the best model available to do a 13B Turbo transplant. It already has several things necessary to make the swap easier:

That is just the GSL-SE stuff. For my particular swap, you will still need:

SUSPENSION

GAUGES:

VDO 3 gauge “A” Pillar Pod with:

Custom Center console covered in Carbon Fiber with:

3 additional gauges under the Sony CDX-MP70 MP3 Player:

EVENTUALLY:

As you can see, MY parts list is quite extensive. Luckily I am about 90% of the way there. I will be completing this list within the next 60 days, and then tearing into the car shortly thereafter. I anticipate finishing by the end of the summer if it all works out.

By the way, this does not include Labor, misc parts, time, time, and did I mention time?
Also TOOLS. Engine lifts, engine stands, Air compressors, parts washers, extra nuts, bolts, aluminum sheets for fabricating, etc. Labor is very expensive, as only a real quality rotary mechanic can do this, unless you know how to do it yourself.

I will be doing most of it myself, with the exception of the fuel system, Haltech installation, tuning, and Dyno testing. All of which is very expensive as well.

As you can see, it is not easy, quick, or cheap. It is quite an expensive toy that will NEVER be worth what you put into it. In other words, even if you do a real awesome job, that looks like factory OEM - you will never even get half of the money you invested into it if you try to resell it.

Why I am I doing this? Because I have always wanted a Turbo 1st Gen since my first RX-7 over 14 years ago. I plan to keep it as long as I can, and make well over 400 hp to the rear wheels. It will be my “fun” car. Not a daily driver by any means.

Before you consider this route let me recommend a few things.
1) Have another Car for daily use (pick-up truck recommended)
1) Don’t start until you have all the parts you need. (you will need more than you think)
2) Unless you want more than 250 hp (which is a shitload for a 1st Gen),
go another route.

ANOTHER ROUTE:

1) Take your (12A) engine, rebuild it, Streetport it, get some nice headers and a good carb (Weber/Dellorto) and you’ll be at about 200 hp for less than $1200
2) Same thing, with a 13B = 230 hp, about $1500

3) Turbocharge your 12A. – Get a Holly 550, a Rising rate Fuel Pressure Regulator, an Intercooler, an old RX-7 Turbo with manifold (modified), a locked distributor, and you’ll be at 220 HP on a stock port 12A, 250 HP with a Street Port. – Less than 2K

4) Turbocharge a 13B. – Get a Holly 550, a Rising rate Fuel Pressure Regulator, an Intercooler, an old RX-7 Turbo with manifold, a locked distributor, and you’ll be at 240 HP on a stock port 12A, 280 HP with a Street Port. – Less than 2200

5) A Nitrous Oxide System. Good only on a Street or Bridge port, you must do this EXTREMELY Well, with plenty of safeguards to avoid blowing your engine. – Less than $500 for the kit, and Extra 50-75 HP over what you currently have.

I hope this has provided you with MORE THAN ENOUGH information concerning a swap like this. Go to the RX-7 Forum, the web and Read, Read, Read.

TII Swap into GSL-SE

Good Luck and keep us posted!

NOTA V6

I'm trying to avoid a solid (metal to metal) mount because I have dental work, and would hate to have it fixed frequently.

If worse comes to worse, I will go with a solid mount, but for the time being, I am using personal contacts to attempt to "fix" the custom mount in the pictures.

You're in Lakeville aren't you setzep? You should come up and take a looksie some time. If you want to, PM me for my address and phone number. I'd like to take a look at your Frankenseven project as well.

setzep

Mine isn't mounted solid, the crossmember has rubber in between it and the body where it bolts to the body. Isn't yours the same? It will be a lot stiffer though because there isn't a rubber trans mount but thats ok with me.

I didn't realise you were in bloomington, damn thats pretty close to me. When are you normaly around?

NOTA V6

I just assumed that those tiny rubber pieces wouldn't provide much in the way of dampening.

How thick is your aluminum spacer plate? I mean how far off the saddle/cross-member does it raise the bottom of the tranny?

Dietbudda

Questipn, will i have to go through this much trouble if i want to swap a normal N/A 13B into my FB RX? See, i'm still a young kid and hev time to do everything i want to do and still need a bit of experince before i start hitting 200hp, SO, i was wondering, would i go through as much trouble to just put in a 13B N/A? Should i get a GSL-SE engine or a 88 13b? I know a 13B 88 has more hp but i'm worried about time it's gonna take cause my 12A just **** itself, so i need to do this Quick, help me out here.

gen1mike

Anyone done this swap into a non gsl-se? Is it very much harder? thanks

Directfreak

iTrader: (2)

Plenty of people have. A GSL-SE is the preferred car to do it to, because it was the top of the line RX-7, and already came with a 13B engine.

Most of the links here are not necessarily for a GSL-SE. Right now I believe there's like 6 of us doing a 13BT swap of some kind here on the list, with a few others who have already completed it.

setzep

Jim- the spacer is 3/4" inch, this raised my transmission up to where the stock n/a trans sat. I could have just left it sit on the crossmember that way but then my driveshaft angle would have been different, though I'm not sure it would make a difference anyways.

gen1mike- My 83 is a non -se model, I did however put a full suspension from a 84-se under my car. Dirrect swap. I'm pretty sure the trans swap would be the same with a 12a car.

hey guys i have been requested to give some details on my jc cosmo to 1st gen conversion

Engine & turbo details

- JC cosmo 13b, 8 extra dowels, large street port, built by dyson rotary www.dysonrotary.com.au
- Custom Garrett TA-45, running T-04 1.32 Exahust housing with P trim, and TA-45 76mm wheel and comp (have exact specs on comp side written down somewhere but can't find em )
- Custom exhaust manifold, with 45mm turbosmart external wastegate.
- 3.5" dump pipe, feeding into 3.5" highflow cat then into 3 custom 3.5" mufflers.
- Turbosmart Vee port blow off valve
- Turbosmart type 1 boost controller
- Pnumatic relieve valve that runs before boost controller so i can remove wastegate creep alltogether
- Large custom Micks Metal Craft FMIC with 3" piping

ECU & Fuel system

- Malpassi rissing rate regulator

Tranny and diff

- Series 5 turbo gearbox
- 1 tonne presure plate, with solid centre brass button clutch

Misc

- Series 4 turbo 16 x 7" wheels (only on the back at the moment as i haven't yet changed the stud pattern on the front)
- Car looks stock from the outside

I think that is about it let me know if i have missed anything

ahhh how much power, the same turbo that i am using has produced 550 RWHP on a serries 4 street port motor @ 28PSI & C-16 fuel, my engine builder said i should get the same if not a bit more due to the larger ports etc in the cosmo engine. Remeber that power figure is on a dyno dynmaics chassis dyno which is popular in Aus, on an american dyno jet, that would be over 600 RWHP

In street trim on pump fuel, it makes around 400RWHP on 14-15 PSI

I have slapped a rough website with some pics and stuff http://members.austarmetro.com.au/~brap/index.html

If you get a chance check out www.dysonrotary.com.au they have an online store and stuff with lots of goodies

cheers

Hey, Found another one. Custom GSL-SE Turbo.

DC's 1985 Turbo GSL-SE

Jerm982

How much more does a 13bt from a TII weigh then a 13b from a GSL-SE?

NOTA V6

This is just a guess, but I think it would be lighter, not heavier. There are more aluminum bolt on parts on the TII motors (water pump housing, etc.), and the rotors themselves lighter too.

It's the stuff the GSL-SE didin't have at all that will add the weight to the TII engine. Turbo, wastegate, and an IC with piping adds up. The TII transmission is a LOT beefier than the GSL-SE tranny too, as is the drive shaft if you are planning on using them.

Turbo FB.

Its easy I tell yah.

just do it

GSL-SE or not, Its all the same as far as puttng the wire harness in.

RX-7-8593

I finally got my 13bt powered 1st gen running. Got the haltech intercooler and piping in and drove it around a little in front of my house. I cant drive it very far I have no exhaust yet just a RB 3inch down pipe its kinda loud. Id like to know what kind of muffler you guys doing this swap (or have already done it) are going to use. Id like the car to be quite so im looking to find a large 3inch inlet twin tip outlet muffler with stainless steel packing any ideas? The only one ive found so far is made by borla but looking at the design it looks like it may be a bit loud. Here is a pic of my car so far I have many more but im to lazy to put them up on my webpage right now.

setzep

Am I blind or did you just forget to post the pic?

As long as I'm posting here I might as well make it constructive.

For any one who is doing the swap to a cosmo engine in the future and wants to use the serpintine belt here is a pic for ya that I took the other day. The belt you want is 5-rib 32" long. They didn't have a 32" at my local parts store so I went with a 32.5 and that works, also by from looking at it you could go from anywhere 31.5-32.5 length belt.

I was contemplating this from day one, however, I want to run the stock Power steering and A/C. Not a Big deal.
I'll just use the FB pulleys.
Revolution Rotary has a REAL Nice Kit for these as well.



They are polished Aluminum too! Too Much money though... $289

setzep

WOW, $289! I think I spent $20 on a belt,paint and sand blasting sand. But of course mine aren't aluminum or under driven

RX-7-8593

Sorry about not posting the pic my computer crashed while I was posting and I did not think it would put anything. Now my network card is broken so im trying this from another computer. Hope this works.

setzep

Looks nice! What did you use for I/C tubing?

RX-7-8593

setzep

The tubing was made by a friend of mine. Its tig welded pieces of 18guage 2 1/4 mandral bent steel tubing. It came out looking really good, it fits perfect. I painted them simi gloss black it matches pretty good under the hood almost looks like it was stock.

fatboy7

Currious ... who is going with 3" exhaust piping, and if so what muffler/presilencer combo are you going with?

NOTA V6

Oooh! I am, I am!

I don't have a PS nailed down yet, but I have a Borla Turbo XL muffler. Single 3" inlet, dual 2.5" outlets. You can see through it no problem though, so I would guess a PS is definitely needed.
