Speed... Thanks for helping with the merge, and cleaning up this thread.

You guys, don't be so hard on Ni... His intentions were true, he just went about it the wrong way.

i pulled a 2.3 out of an xr4ti recently and have plans on putting it in my fc and was wondering what are you going to do about the driveshaft, i am using a t5 out of a 8cyl mustang with the bellhousing out of a 2.3 mustang,

JesterJess 04-28-06 10:41 AM

You will have to take the back half of your RX7 shaft, and the front half of your 2.3 shaft.... Take those to a driveshaft shop, and have them custom build you one. OR, you can order the shaft from Granny's... Along with your kit.

91BlueS5 - remember, to do that you either need the right pilot bushing or get the input shaft machined. Turbo Ford Forums has threads about that swap and part #s and sources for it.

Also, you can get an adaptor plate made for a 2.3 to use a v8 bell and v8 clutch - just throwing that out there for people who might not like pucked 8 springless clutches.

JesterJess 04-29-06 11:00 PM

Update....

OK, I pulled the subframe out. Bingo, the flywheel, clutch, and bellhousing are now installed.

I'm ready to stab the tranny in there, just need a hand. I will get that in tomorrow, and install the tranny mount. As soon as I have that, I will let everyone know about any issue with the rack.

Fire 'er up!

There is an early 80s mustang svo sitting out in the grass at the farm where my project is. I bushwhacked my way over to it yesterday looking for a spring to pilfer for my clutch pedal. I saw the cute little I4 under the hood with a cute little turbo strapped to the side, and thought of you.

Not that Ill be around in time to help w/ the tranny, but Id gladly lend a hand w/ the rex or any other car :bigthumb:

Also, any advances with hood fitment yet?

88IntegraLS - lucky bastard... that should have one of the 60 trim T3s. Too bad its so damn far away!

88IntegraLS 05-01-06 01:19 AM

I doubt it has a title but Jester PM'd me about it. I'll check into it. Pics next weekend. Most of the motor is still there.

JesterJess 05-01-06 06:42 AM

Ni, I could use the hand. I am having my wife help me this week, if I can get her to slide under the car, and get dirty with me. Also, I have no advancements with the hood yet, I will most defnatley go with a Mistu bubble though, just need to source some parts first.

When are you moving down again???

Jester

Nihilanthic 05-01-06 01:12 PM

Prolly late summer... Id hope you wouldnt be still hanging by august! Im personally going to go with a lower mounted alternator and a custom (or just chopped stock) intake to clear the hood... think the pully will clear it?

Also, jsut to all - are there ICs out there that are big but have the inlet and outlet both on the same side? It seems as though the "crossover" intake would clear the hood, but that would mean Id have to use really long IC piping if It has the outlet on the other side of the IC.

JesterJess 05-01-06 03:14 PM

Cool, keep me posted on your arival date. I can't wait so we can get two RX7's with 2.3's lurking around.

I am going to use a Porche intercooler. There is plenty of room between the radiator and the crank pulley for the I/C.

Jesse

skylinekin 05-04-06 07:45 PM

sweet project, I am still considering this swap or a LT1/T56. Cant wait to see some pics and videos when its complete!! Keep up the good work.

Rob B. 05-06-06 09:22 PM

+1

Now that I think about it I should have gone with the 2.3 in my car instead of the 13bt.

Then again my car is an Opel GT. (theres a guy who runs GRM's 200- challenge each year with that setup...uber cool)

-Rob

Nihilanthic 05-08-06 09:35 PM

Also, I just found out Ive been misinformed about a 2.3's strength just now. *Groan*

At 450whp you need to replace rods and pistons, but the crank and block are actaully good up to just under 700whp. So, othe than the bad spooltime/ possible surge if you dont use the juice with a turbo to support that power, a 2.3 is just fine.

Actually, considering its ligther than a LS1/302 with the iron head, and the aluminum head can give you serious flow and ligther weight, this is actually a damn good option for dragging. And with a properly setup paired-runner exhaust manifold on a HX35 or HX40 (or a hybrid!) you could probably get some sky high power and good spool. Hell, HX35s spool great and can crank out 60 lbs/minute at max (supposedly, never been pushed all the way yet tho) and there are the likes of the GT35R out there.

Im already set on this, but I felt like I should correct my previous mistake... and maybe convince a few others to take the plunge :D.

JesterJess 05-09-06 05:41 PM

OK all, tonight is the night. I will actually get my tranny in, and get the crossmember installed. I will shoot some pics when it is done. I will also let you all know about how the crossmember from Granny's works along with the new energy suspension mount I picked up.

I'll shoot some new pics for you all also.

Nihilanthic 05-09-06 05:47 PM

BTW, new tentative date is late July/Early August... ;)

Oh, and if you see this before you do the pics, could you look at clearance from the bottom of the motor/oilpan to the crossmember or the anti roll bar?

Anyway, goodluck! You should be tearing ass around florida in no time. :D

Nihilanthic 05-11-06 04:33 PM

BUMP.

Everything alright there Jess?

JesterJess 05-11-06 07:17 PM

Nope, I have an issue with getting the tranny on. I have about 1 inch left, but I just couldn't get it any further by myself. I am going to work this weekend to get the slave master cylinder in, my clutch line ran, so I can push the cluth in, while I stab the tranny the last inch. I have tried everything, and I have done 10-15 of these in the past with no issue. I don't know, maybe it's just RX7 Karma starting to catch up with me.

As far as the clearance goes, I really don't know yet. I will be swapping to a manual rack. Does anyone know if they are less of a diameter than the power rack???? There is plenty of clearance for the crossmember, at least the front one. I yanked the rear one for now, I will keep you posted on weateher or not I re0install that one. I have no new pics yet, as it just looks like a dirty mess of a tranny, that is not all the way installed, hanging in by 4 bolts and the crossmemeber.. Which by the way, Grant's crossmember fits good, as far as I can tell right now.

Eh... I'm not a huge fan of Holset turbos on smaller engines. Holsets are practically bulletproof, and they're great in that respect, but for performance, I think there are better options (of course, Holsets are everywhere so they're easy and cheap to find).

The GT35R is in a totally different league, and is a much better (and more expensive) choice. The spool on one of these is actually more than I was expecting for a 2.5L 4-cylinder, especially an 8-valver like the Porsche 951, but it's pretty damn good for a 65 lbs/min compressor.

With regards to compressor ratings, I believe a Mitsubishi TD05 small 16g is rated to about 30 lbs/min max, but I'm currently pulling 34 lbs/min out of mine. When you go that far off the map, you better have a good heat exchanger!

The guys at TC said they dont use it at all. If you get it to fit, by all means use it, but its hardly necessary if they've gone this long without it!

BTW, is this the same tranny that was on the motor to begin with? Im just thinking of 'duh' overlooked things, if its a v8 T-5 with a 4banger bell you might have the wrong pilot bushing on it, and the uh... merkur didnt have T-5s stock itself, so there might be issues with that. Not sure, never messed with a merkur before, but I do know they used a "T-9" or some such transmission.

Anyway, sorry for ya about tranny issues like that. Ive had one make me spend two days fighting it (and a trip to the hospital after falling off a tranny jack and on my stepdads ribs) before.... I guess everyone has to have one be a bitch sooner or later :wallbash:

88IntegraLS 05-13-06 07:32 PM

Here is that Mustang which I believe to be an SVO with the turbo I4 in it:

https://www.oregonstate.edu/~quinnj/svo1.jpg

I didn't make an effort to get the grass out of the way, but the turbo is barely visible to the right of the valve cover.

Some guy who works here once in a while has a turbocoupe sitting around somewhere else. He says it's his sister's but the damn thing hasn't moved under its own power in years. Turbo fords abound in these parts.

JesterJess 05-13-06 08:01 PM

NI, tranny came out of the TC, everything is being replaced from where it was taken.

Integra, that is a shame, but for what I can see, that is a lost cause. If you can pull a vin, I would like to see exaclty what you have. If it is a comp prep SVO, it would be worth draging out, but if it is just an old 83 turbo 4, it could just rot.

Nihilanthic 05-15-06 11:55 PM

Hows that tranny and x-member going?

JesterJess 05-18-06 09:51 PM

Still having troubles with getting the tranny into the pilot bearing. I think that once I get the clutch system installed, I will be able to push in the clutch and get it to slide in. Then I can mount up the crossmember, and finish that part of the project.

TONIGHT: I just re-pinned the wiring harness, removed all/most of the things I will not need. Then I wrapped the whole thing up in Harness Tape. I was at a swap meet and found REAL harness tape. Not plastic like electric tape. This stuff is made of a chloth material, and it rocks. It is real sticky on the bottom, and slightly tacky on the top. This stuff is not like hockey tape, but kind of down the same line. It will not hold moisture.

So, tomorrow, I get to run some hose for the clutch slave cylinder and run all of the wires. I will also be mounting up the computer in a custom bracket that I built out of parts from the stock computer mount.

I will upload pics when I have them.

I was wondering.. is this the same car?

If it is, what happened? Loose interest, or going to a new project?
