i'm not as familiar with the EFI setup. I want to know if a 84-85 SE throttle body will fit on a 86-88 N/A upper intake manifold.

Thanks,

 

no and anyway why you want to do that, 86 and up have larger throttle plates

 

I thought about that after I asked. Here is my set up and the problem I'm running into. I got 2 N/A short blocks, and a TII short block, all '87s. I'm using the turbo rotors, rotor housings, and center plate with the N/A end plates to make a 6 port turbo. So I need the 6 port LIM. The turbo UIM doesn't fit together with it, so I need the upper and lower 6 port intake. The turbo throttle body doesn't fit to the 6 port intake. So I need a N/A throttle body. I was wondering if the SE throttle body would fit. I had a brain fart cause I said to myself "if everthing is going to be N/A intakes, then why not use a N/A 87 throttle body duh?"

 

why would you convert a turbo motor to 6 port.

 

The parts I'm putting together have the largest ports. The TII center plate has larger ports than an N/A center plate. The N/A end plates have larger ports when the aux ports are open. I'm going to put the pineapple sleeves in the 5th and 6th ports so it will have better flow. I originally planned on doing this with a supercharger, but I figured since it a project, why not make it a more challenging and complicated project and see if I can turbo charge and fuel inject the whole damn thing. It would be easy to slap a SC and a carb on it. Right now I'm trying to figure out what combination of intake manifold and throttle body I will need. I had a thread a week or two ago about this, and nobody could come up with a significant reason as to why a 6 port turbo would be a bad idea so i'm going for it.

 

If you already have a TII shortblock, I would recommend you use it. Use the TII intake and everything will bolt up for you. The flow increase with pineapple racing sleeves over stock sleeves is only 1% better.

If you remove the sleeves (better for top-end turbo) the different port matching might make it difficult to tune and you might have a weird powerband.

Don't get me wrong, I like your idea. But if you already have a good TII shortblock, it will be easier in the long run to use it and all it's goodies, than to frankenstein then engine as well. If you only had a 6 port engine, then use that. Or if you only have certain parts here and there, then I could understand the mixing of them as well. Again, if the TII is good, - use it.

As it is, you're gonna have to do some fabricating, so keep it to a minimum if possible.

Good luck.

 

The TII block is good. What will I need to fabricate that I wouldn't need to make if I used the entire TII engine block? I'm to the point where I'm going to put the motor back together, and from their, I either have to go down the turbo path or the SC path. I don't know as much about the EFI setup on rotary engines, so I've been researching through here, the Haynes book, and the FSM. I'm not sure about the order of some of the vaccuum operated stuff. I don't need the emissions stuff, so I'm trying to sort out what is emissions, and what is necessary for a turbo to function properly. Any insight will be helpful.

 

Well, If you use the stock TII block, you could use the stock TII intake, and thus - the stock TII Turbo and manifold. If you use any of the N/A intake, you won't be able to use the stock manifold without some work. Also the stock TII throttlebody is larger than it's N/A counterpart.

If you can, keep it simple and do a blow-through carb. Sure it's not as smooth, but the power will be there, and probably at only 1/4 the expense and trouble that the Fancy EFI route can cost.

You can always go EFI later if you insist.

 

Who makes blow through carbs?

 

You do. You get the carb you gonna use and have it modified, rejetted, and then put a carb cover over it.

I recommend a Holley. It's a proven combination in blow through applications. I have a friend who puts these together in his sleep he's done so many of them.

He's finishing up one right now. Here's a little blow through system on an RX-3. It ran 11.30 in the 1/4, and it hasn't even been tuned yet.

 

wooooot
hooray for holleys! hehe yeah
whys the bonnet facing backwards? why not forward and using less piping

 

I pretty much spent today doing online searching and looking through my books trying to see what I would need to support a turbocharger. To follow Directfreaks advice to keep it simple, I may end up sticking with the supercharger. It would be more simplistic, plus I am looking at a 86 GXL to buy, but its an automatic. I'll have to to a tranny swap, so I'll need the money for that. You may be thinking that a supercharger is not cheap, but our base just got our deployment order, so if I go over to the middle east, I'll have a lot of money saved up when I get back. Not enough to buy a FD or anything, but you know what I'm saying.

 

Probably to leave room for plug wires... or maybe just to make people ask this question... LOL

all i can figure is the oil filler neck and dipstick maybe? cause the plugs wouldnt be much worse than a car thats got ac & ps

 

Think mnaybe he might want to add oil during an oil change? See where the oil filler neck is in relationship to the bonnet?
