Or acctually any 2nd generation motor for that matter, but I am wondering who has a 1st generation and has put a 13B NA/turbo in it. And did you have to make new tranny/motor mounts, or are they the same?

That is pretty much my main concern, because would like this to go pretty fast.

 

you have to swap the front cover plate, get a GSL-SE oil pan and get a modified motormount brace. every thing else is bolt in.. if your going form carb to FI, you need to get the wireing harness and computer. and swap that in. as well as underdash wiring, and fule pump.

look here this will help

o yea.. racing beat sells the brace

you may also get away with the oil pan on the 13 you get but you will have to drill new holes to make it line up with the holes on a 12a or 1st gen 13b front cover plate.

 

I have heard everyone say that you need to put the front cover and oil pan. Why does everyone do that? Instead of just useing the stock 13B S5, or what ever front cover is on the engine for that matter.

 

you cant use the one on an s4 or s5 motor. because in the second gen the motor mounts are on the side of the motor.

on the 1st gen its in the front sooooo... the front coever plate on a second gen motor will not have the spots to bolt up the motormount brace... thus no motor mounts and your motor is draggin on the ground.....

as for the oil pan.. the hole location on the front cover plate on the fisrt gen is different then on the second gen.

 

Really!

That's seems weird, I'm just used to the motor mounts in a different place.

 

yea... forgive me thats it.. the mount location is differnt. on the second gen the mounts go on the side of the motor. on the first gen the mounts hook up to a brace that bolts in to the front cover plate... so there in the front of the motor....

thats the ticket.

 

droping the motor in is the easy part... most people have a hard time with the carb to efi. wiring can be a bitch.

 

Well, I was thinking that I could just get all the wireing harness's that I need out of an S5. And use them, but I may be dreaming on that one.

 

yea.. ive been looking for a good wile for a good condition S5 TII harness. good luck..

also on a side note.. you will have to swap the OMP on the s5 to the s4 one. the s5 is electric and will not fit in the front cover plate of a 1st gen there are some who made it fit with moding. but the mechanical one from an S4 pops right in.

 

Yes, but if you don't have the electric OMP hooked up to the S5, it will throw codes in the ECU, and cause it to go into limp mode. So it has to be hooked up, unless I were to buy a stand alone ECU (which isn't going to happen)

Also, if I do this swap, I am going to use an S5 NA not the S5 turbo.

snail under the hood= trouble/money pit.

 

yep... it will throw a code... like i said wiring is a pain in the ***... maybe some one else will chime in and say some thing... all this will give you a nose bleed lol....

i think the best way to go is s4. or S5 but swap out the map sensor. and run the flapper of death. with the s4 harness and comp.

 

I HATE ELECTRICAL CRAP


The rest of it is pretty easy for me to do.

 

Amen to that


you could always go 13b carb my old set up was nice. S4 13b N/A with a weber 48IDA. no electrical there.

 

Yes, but the S5 NA's have a nice stock intake, and I kinda like it, along with the fact that a nice carb setup is about $500 or so.


But I love the thought of the carbed 13B

 

the N/A 's have a lot of power to be set loose... i have a friend with an 90 N/A who just did the basics, intake and a pimp *** exhast.. (real duel each rotor has its own pipe and muffler no y pipe.) and he had no prblem keeping up with my other friend with an 87 tII with just an intake. TII still one but the N/A gave him one hell of a run for his money. i cant say if it was bad driving or what but the N/A felt realy good. so in a first gen it would be nice.

 

Yeh, that's why I want to put it in a first gen, because it would be very respectable. And half way reliable. Also the motor that I am looking at (if the guy comes threw on the trade) is a 20,000 mile rebuild, with a street port. And he said it was running 10 second 1/4 miles. Which I have doughts about, but if it was going that fast, it would be a complete and all out beast.

 

10's? hmmm with a big *** shot of No2 lol.... or a fatty turbo... maybe both... what was it in? a cardbord box with wheels?

 

I am guessing it was in a stock S5 NA, I'm not sure

 

hey guys i own a 87 tII and i just cant stand the elctrical **** sensors and sensor way too much amoney and way too much **** so im coming to you guys to find out how to changemy 13b to a carb power rotory please help me sites cost anything please

 

oh god please dont do that... if your car came TII leave it that way. i would hate to see a TII pop the hood and its N/A Carb. if your going to do that atleast Go Turbo Carb. even that FI is a lot better in my opinion. and if you do deside to go Carb i will kick my self because i would have done a full swap for my 13b carb set up. but i sold it! wack!..

stick with the stuck set up.

 

There are people that have carbed there turbo 2nd gens, but I can't emagine that it would be more efficent, or more powerful than the fuel injection setup.

And there are tons of things you can do to clean up your engine bay, just search the 2nd generation section, and you'll find more than you want to.

 

yeah but im pretty sure itll be a lot more easier to work on im to much in a budget and i want my fc so going on a carb i think will be the most confortable and easiest way

 

Acctualy I have heard that carbs are rather hard to tune, and go out of adjustment rather easy.

But it is all in what you want.

 

yeah i know the tune has to be always maitained on carbs but its also a lot easier then testingall the sensors
