ok well i've been wanting to get a project for some time now. i've been in the new member question area deciding if the FD i had my eye on was the one for me...or if any FD is right for me for that matter.

after much deliberation i took the plunge and bought a 93 FD. the car had been sitting up for a year as the previous owner began going single turbo and got called to duty. with his life plans changing, he put it for sale. this is where i come in.

after a few visits to the car and many questions from me the deal was made.



yesterday the car was delivered. i was pleased to say the least.

here's what i started with




that's the car when i first saw it




i began by giving the car a wash. it's been sitting awhile and before i move it into the garage i wanna get all the leaves, mud, spiders and frogs outta the equation.

once i was done washing the car i went ahead and washed my daily and by the time i was done it was dark. this morning i got up and snapped a few quick pics to show you some more of what i'm dealing with.

 

here's the single that the previous owner bolted up. just a t3t4.

nice size intercooler



what a mess


the car also came with a few electronics that were previously hooked up


also came with an fsm, bov, and many, many other parts. all oem parts are in the trunk along with a few more aftermarket.


also came with an aftermarket front. will probably use it after everythings together.

anyway, that's what i've got for now. the engine was rebuilt 2 years ago so all the seals should be good. i just wanna work out all the wiring. i don't want it looking like **** under there. i think i'm going to return the car to stock for now until i decide what route i wanna go exactly. after i make sure the twins are ok i'll probably bolt them back up and begin replacing all the hoses and making sure that's all sorted. then i'll move on to the wiring i guess. ughhhh, i ******* hate wiring. i always want it to look perfect. guess with this project i'll learn to do it properly. i may try and use the aftermarket intercooler that's on the car now with the stock twins. i really need to sort out everything i've got just to see what all is there. if i get off in time tonite i'll probably do that. anyway, i gotta get ready for work now. just wanted to share with everyone.

questions, comments, advice, and concerns are always welcome. thanks for looking.

 

I hope you'll change that wing!

 

why? it helps with down force

anyone know what kinda wing it is? i havent given it much thought.

 

when i got home tonite i figured i'd clean and inspect the twins. they cleaned up ok for just using some degreaser and a brush.



and then i found this



small cracks in the manifold. i'm worried about them kinda. usually cast iron doesn't hold up too well after being welded.

any suggestions?

 

so today after work i came home to kinda get an idea of what it's going to take to put the twins back on. i began unloading the car of all the parts, oem and aftermarket. this is what i came up with





...yea...

well needless to say i was alittle overwhelmed. i think i'm gonna just follow out with the completion of the single turbo. i've decided to take the intake mani off and clean it up and do alittle p&p. when i took the upper mani off i saw the mess of wires and tubing. it looked horrible.

is there a way to simplify all of the wiring and vacuum lines? what else do i need to do in order to go single turbo? i'll probably make a post in the new member for as well. if you would, please give me some input on the situation please.

also, i took a few shots of the interior to let you all see the mess it's in





don't let the seat covers fool you, the seats are in horrible shape really. the original carpet is covered with some other type of black material. mostly all of the panels have been painted black unfortunately. i dunno if i wanna just take it all out and leave it gutted or what now really. i guess i'll get to that when i get the car running.

 

Looks like a lot of work, have you try to start it?

 

yea i charged the battery alittle and turned the key and it turned over and wanted to start but i didn't go all the way with it because the exhaust isn't hooked up and neither is any of the ic piping.

 

Pretty sure that the wing came from an Acura Integra around 1995!

Good luck with your built! (swap it manuel )

 

thanks.

anyone have any links or info on going single turbo? i've found the vacuum diagram and that's a great start but i'm definitely going to need more info

 

OP,

There are tons of threads on converting to a single. Please search in both the 3rd Gen and Single Turbo forums. Also, please read the Frequently Asked Question sticky in the 3rd Gen forum. Lots of good info there.

Here are two quick links to some single turbo information.

Make sure that wastegate isnt rusted shut from sitting so long. It happened to me on a car I tuned... Kinda scary!

 

your going to need aftermarket ecu to run single turbo, also i would recommend buying a complete bolt on new or used turbo kit to replace that ebay turbo and manifold that the previous owner installed.

 

Thank you for the links. I did try the search function but it seems like I never have much success with it. I dunno if I'm searching for wrong terms or what. It wasn't until later in the nite I found the single turbo section just browsing around.

Is the apexi pc ok to use or would you all recommend something else?

I do want to eventually get another turbo setup but I don't wanna spend alotta money right now since I'm just beginning to learn more about the whole turbo setup. I just don't wanna spend alotta money and damage something because of inexperience.

 

if you go stand alone you could delete the rats nest of vacuum lines and oil lines and it would make the single turbo conversion much easier haltech and microtech are the two e.m.s. that i like.... you have got a pretty lovely find that most of use will kill for it may seem like a lot of work but in the end it really is worth every min and every dollar spent ... just do your research and learn as much as you can from other more experienced members and you'll be fine

 

i was reading the single conversion posted in the link above and i see where you can simplify everything and remove the rats nest. i'm off the next few days. gonna try and get a good bit done.

i also want to get the set of block off plates from banzai so i can further simplify everything. if i get the power commander from apexi will that work as far as an engine management.

 

so last nite i decided to go ahead and order the block off kit. the other day i started taking off the intake manifold before it got dark and i only managed to get the UIM off before it got dark and i stopped for the day. today i went out and took off the LIM and cleaned alittle. it started raining shortly after i had taken the manifold off so i decided to fire up the compressor and clean the runners with a flapper wheel. i did alittle of the upper mani and while the lower was sitting in degreaser i took the intake elbow that came with the car (unknown brand) and began cleaning the inside of it as it was alittle rough. my compressor started getting hot so i called it a nite.

i think tomorrow i'm gonna take off the turbo and manifold and examine everything. i also wanna take off the coil pack bracket and clean everything up around there. i need to get a big box and start putting in all the pieces i'm gonna sandblast. i think that'll probably be the best thing. after all the block off plates are installed and i figure out which plugs i don't need i want to either remove them from the wire harness or tape them back. the wiring harness is in rough shape so i'm wanting to take it off and rewrap it.

alittle question about the engine harness, since my state (MS) doesn't have emissions should i just go ahead and remove the sensor connectors i don't need? i think it'd be cleaner and i don't think i'm gonna need them in the future.

 

i would wait to cut any connectors until you figure out what your going to do as far as engine management it would suck to cut and remove something only to find out that if you would of kept it it would have helped with tuning or just initial set up i don't really know much about apexi but i know haltech and aem give you the most input output slots to run certain functions like a/c, power steering, oil metering pump etc.etc.... but you could get by with a microtech that are simple and less complex then most e.m.s.

 

you're right. it would suck to need a plug and not have it. i know there are some connectors i can definitely cut tho. just not sure which ones. i think most of the one's on the intake mani that are blocked can be cut right?

also today i found this in the 2nd intake port (the smaller one closest to the firewall)



i know it can't be good. what is it? i can feel another one in the other small port as well.

 

That would be your injector diffuser.

 

is it a big deal that it's broken? i'm guessing it'll just cause some fuel not to be burned off properly huh?

i've never seen anything in an intake port before. sucks i had to see it like this.

 

Your injector diffuser helps with the atomization of fuel. There are a handful of people that remove them because they do break. Ask Howard Coleman; they wrecked two motors of his while tuning with 100% meth. :P Most suggest removing them MAY diminish the quality of your idle but that is about it. If you move onto new/bigger injectors I.E. Injector Dynamics or Bosch EV14s, then it's said they have a better spray pattern and a diffuser is not needed for the atomization of the fuel. You can get new ones from Ray @ Malloy Mazda for fairly cheap. They should be replaced when you send your injectors in to be flow tested and cleaned along with new O rings and a fuel pulsation damper while you're at it. :P

yeah what he said haha as far as the connectors i do believe most of the mani connectors will end up being deleted but i wouldnt be sure which one unless i knew what you had in mind as far as the e.m.s. and the car its self like is a street car or full race then if its going to be drag or circuit your possiablities are endless so i would be sure of what you want to do with the car before just getting ride of things

 

how are the injectors diffusers installed?

as far as removing the plugs and all i guess i won't mess with too many of the plugs. i've got an auto trans right now and i'll most likely be using the apexi pc for engine management so i'll check and see which plugs i can remove for sure.

as far as plans for the car, i really wanna use the car as mostly a weekend toy but also be able to take it out for cruising and meets. i'd like to get into alittle bit of racing. not much around my area tho. people mostly drag race here. i wanna be able to corner and sill be fast. maybe scca or some type of road racing. i'd eventually like to be able to take the car to different tracks around the south and have some fun but that's a ways away still. for now i'd be happy to get the car on the road and go hang out at a few of the local meets.

 

The diffusers are installed from the top. They go in first then you seat the injectors. I would stick with the injectors I specified as they come high impedance and do not require resistors to use with the power fc.
