13B 6 Port Turbo Project
 
Alright, so I'm finally getting things going. I have an 85 S model RX7 that has a very nice 13B 6 port motor in it. The motor is stock port but is very strong and runs great. Right now I have a Weber 48DCOE carb with Racing Beat upper and lower manifolds, with a full exhaust this is quite a powerful setup. At the moment I'm in the process of adding turbo application to this car, so this is the beginning. I'm planning to use the following for this setup..

Stock S5 turbo
Custom turbo exhaust manifold (RotaryShack)
Custom mandrel 3" exhaust (RotaryShack)
MSD fuel pump
Mallory fuel pressure regulator
MSD blaster 2 coils (2x)
Locked dizzy (RotaryShack)
6 Puck Race Clutch and upgraded PP
Intercooler (?)
Custom Carb Hat (RotaryShack)

Right now I already bought my clutch and fortunately do have a very nice oldschool Spearco intercooler that I might use, might not right off the bat. I'm in the process of purchasing the custom carb hat, fuel pump, FPR, and down pipe. Also already have one MSD Blaster 2 coil just need to grab one more off ebay or something. So, right now I'm in the market for a used S5 turbo and once I get that, will purchase the custom turbo exhaust manifold (expensive). I will be posting pictures up as I get new items and once we do the actual install. I plan to have this turbo setup complete as well as a nice new paint job before Sevenstock XI so should be interesting to see the completion progress. For people who are interested in learning more about blowthrough turbo setups this thread will help. This is semi-cost effective way to do it and depending on your motor could turn out well.

Look forward to seeing pics of the intercooler and clutch setup tomorrow. Here's a picture of the car and engine bay as of now:

Also, for anyone in socal that has an FB, Once I do this setup change I will be selling my racing beat road race headers (dual inlet/outlet) as well as my racing beat street port prima flow muffler, so if you wanna call dibs on either let me know. The headers sell new from RB for $240.. with tax and shipping probably comes out to $290, i'm willing to sell for $200 shipped or $175 pickup. The muffler sells for $315 new so probably about $380 tax and shipped.. I will sell for $275 shipped or $230 local pickup.

sweet ride, GL with the blowthrough setup, very interested, subscribed!

Kerebrus 08-22-08 04:13 PM

Thanks buldzor, I'm hoping everything works out great.

Update:
Ordered a stage 2 clutch from F1 Gripforce arrived this past weekend and is being installed today. The 6 puck race clutch seems to be good but like I said I will eventually need to get the racing beat pressure plate, the one it came with isn't that great. The carb hat, MSD fuel pump, and Mallory FPR will be arriving next week friday. I might be picking up the turbo this weekend and if so will throw up some pics.

I know this is a stuped quetion,but what size is the radiator fan??? :) .Sorry for hijaking your thread...

Kerebrus 08-25-08 02:26 AM

Update:

So, the carb hat plenum and MSD fuel pump will be arriving this friday. I'm also purchasing a S5 turbo off a j-spec motor this week as well. Finally, on friday I'm getting a brand new 2-1/2" downpipe from racing beat. All that's left will be to buy the Mallory FPR and get the custom turbo exhaust manifold from my mechanic. Still debating if I'm going to use the intercooler or not.

Use an intercooler! I have a W2A here with me.

W2A? What's that? Haha. I want to use one.. but I gotta figure out how much more it will cost me for piping and installation..

Water to Air intercooler. More expensive, etc.

But if you went air to air, it would cost about 200-300$, depending mostly on your core. EBay will be your friend for the core and piping. Piping usually runs about 50$ a set, for good pipes that you will use, comes with couplings. Just don't go too big on the IC, and if you go in on one side and out on the other, you will have to relocate your battery. PM me if you have questions :)

I already have an intercooler to use and it's a perfect size (will post pics later), but yea I would need to get piping and find out how much to install. Very interested though :)

I bought it from a buddy who lives about 25 minutes from me, who originally bought it from RotaryShack. If you're going to buy a Weber and want it to be prepped nicely, get it from rotaryshack :icon_tup:

trochoid 08-26-08 06:04 PM

XS Power on eBay has decent intercoolers and custom turbo headers for 13Bs. Stay away from their turbos. The manis they have are setup for T4 turbos and fit around the TII intake mani. There are ways to mod either stock S4 or S5 turbo mani to fit around the SE intake. It's not that expensive to do, takes a couple of header flanges and 2 short pieces of schedule 40 pipe. That will tilt and push the turbo away from the intake runners. The same mods can be done to XS Power's turbo header and the oem turbo can be used by changing the mounting flange.

The way the XS mani is made, extending it out may cause clearance problems between the turbo and inner fender if the above mentioned mods are made. I have test fitted the XS mani and turbo on an FC and clearance is tight.

If you have any other questions about modding the exhaust mani, PM me.

trochoid 09-02-08 04:52 AM

Couple of suggestions. I'm always leery about using used fuel pumps, even more so in a turbo application. If you plan on using an intercooler, check out XS Power on eBay. Here's a couple that would work on a 1st gen.

http://cgi.ebay.com/ebaymotors/ws/eB...2BSI%26otn%3D4

http://cgi.ebay.com/ebaymotors/XS-Po...spagenameZWDVW

As far as a fuel pump, a stock SE pump will meet your needs, or a less expensive external Walbro 255 lph. Either way, I would upgrade the fuel supply line to 3/8", the stock 12A line will be to restrictive for a high pressure/volume FI pump. You'll need to look into adding a surge tank to insure a constant fuel supply. It's all of the little needed mods that really add to the price of going turbo.

I've also modded a few fuel tanks to accept the complete 2nd gen in tank TII fuel pump assembly. This eliminates the need for a surge tank and in some cases, a low pressure lift pump to pull fuel from the tank to feed the FI pump and surge tank. If any of that interests you, PM me. You probably should read up some more of modding fuel systems for turbo applications on a 1st gen. If they are done wrong or inadequately, then you'll be rebuilding the engine due to detonation.

If you need a reference on tank mods, PM dj55b or Dan S Young. I've done both of their tanks, one is a turbo, the other is an NA-FI. I go completely through the tanks, having them boiled out, resealed, stripped, repainted and undercoated on the outside. Basically a new tank by the time I'm done.

Kerebrus 12-02-08 02:34 AM

Update:

So after a while of doing some cosmetic work to the car, I'm ready to get back on track with this turbo setup. I was able to pick up and old HKS 6 port turbo exhaust manifold that I'm going to use (thanks Royce) as well as a Carb Hat that needs a little modifications. Going to have the manifold cleaned up soon (thanks Fris). With this turbo exhaust manifold, the S5 turbo is out of the question. I'm going to be looking for a T4 turbo, perhaps something along the lines of a t04b, and something similar to an HKS 40mm standard wastegate. I'm going to be doing some other upgrades such as ordering the RB street/strip clutch and pressure plate, as well as an RB lightweight flywheel. Once that's all installed as well as new aftermarket FP & FPR, I will be close to completion! Here are some update pics of the parts.

Glad you're happy with it. I'm sure it was worth it, the manifold should be good to go.. and the carb hat.. I can have it cut and re-welded on the right side I need it for like $60. So it's all good, thanks again! :icon_tup:

buldozr 12-02-08 03:04 PM

^ If you can get the Iron manifold to work out for you, that would be the better bet. The stainless mani's are of course prone to cracking so if you can get it sand blasted, lap the flange, replace the studs, that manifold will treat you right. 40mil wastegates maybe a little small for controlling lower boost(not sure, someone might need to chime in), just seems like running high comp rotors and low boost the wastegate may have trouble keeping it from spikes/creeps. GL with the project! Keep this thread alive.

Thanks for your input. Yes, I'm already planning to have it sand blasted and replace the studs. I have no doubts it will treat me right. :)

Ordering my RB Clutch/Pressure plate/Flywheel this weekend!

Taking the car in to have the RB clutch, pressure plate, and lightweight steel flywheel installed. FP and FPR are next. Right now the carb hat is being modified at a shop for my sidedraft and the exhaust manifold is being sand blasted/fixed up. Hoping to see big improvements with the new clutch / fuel setup before I turbo the car. :D

cds00bsmg 12-23-08 11:31 AM

First off, nice car, great project. Also, where did you get your wheels at?

Also, great score on the manifold. Another source, (if still available) would be Renee at RX3mist. He can custom make you a tubular manifold, and his prices were very affordable. (He made FB II's manifold, that utilized a S4 flange, placed the turbo higher and towards the front right of the engine bay.) SKYLANCE now has it on his car, I had it for a short period but never utilized it.

Is your mallory FPR a rising rate regulator that compensates for boost? Enlarging the fuel return and feed line is also a good idea as sugested earlier. You may also want to consider a 255lph fuel pump, or just go all out and get an innovative.

Have you considered, or purchased a wideband? Other future options could be getting a FMOC off of a FC also.

Good luck, happy holidays-

I'm happy with the FMOC on my car now, works great! Also, I'm going to be using the following. Fuel pump will be a MSD 225lph, and the FPR will be a Mallory 4309.
Thanks for the tips and advice on the other stuff :icon_tup:

Robert says you can use your current clutch set up with a TII tranny, just need an RX-3 bell housing. That's what he told me.

I am planning on a TII swap after I get the motor sorted. First things first.

I just know with the stock tranny I top out at around 120 in 5th gear.

Can't wait to see this project done, you are gonna have so much fun.

Who's helping you with the build?

this is true,all you need is the rx4 bellhousing,your existing clutch set up that you got already,and the tII trans,also might have to shorten the rod on the shifter housing about 2",so it sits in the stock location.


btw i have a s4 TII trans for sale,and a complete rx4 trans thats for sale also,i was going to use them so i can mount the turbo trans on my rx2,but it's just over kill for my little 12a motor.

Kerebrus 12-24-08 01:31 AM

dave, yea I was talking to you about that trans. I'm just not in the market for dropping $$ on a trans im not going to use anytime soon.. right now my main concern is dropping $400 on fuel stuff/install. I'm still thinking about it though, will let cha know. thanks man!

I did not notice you had the FMOC, my mistake. You may want to consider going with the aeromotive (think that is the brand) EFI pump. Talk to Robert and see what the limits of the 255lph are, and if you would ever exceed them.

Lastly, you never said, where, or what kind of vehicle, are your wheels from?

No worries! Robert was the one who recommended the 225lph so I'm sure he feels it will be effective enough. In regards to the wheels, they are an aftermarket model from ARE (American Racing) that look just like the Enkei mesh ones. These are 15x7 with a +7 offset.
