I am currently working on replacing my clutch in my '93 FD and wanted do a few more things while its winter and I am working on it. I have a list in mind of things I'd like to do but I wanted to get input on the order and if I am missing anything crucial. Just to keep in mind, my future goal (like many others) would be 500hp. Currently the modifications include intercooler, aluminum ast, boost gauge, dp, cb, intake, bv, coilovers, drilled/slotted rotors, and soon to be twin disk clutch. The engine has 62k and hasn't been rebuilt yet. Also, I premix with every fill up. Now for my list:

1. Duel oil coolers (get the stock one cleaned/refurbished and get another stock cooler for the secondary)
2. ECU (I was leaning towards adaptronic but I'm still not sure. I might just go with the PFC. Input on which would be great.)
3. AFR gauge
4. Oil temp gauge
5. Water injection (probably get a Greddy elbow and tap into that)
6. Fuel pump (supra tt)
7. Fuel rails, 1000cc/2000cc injectors, FPR
8. Boost controller
9. Engine rebuild and aggressive street port
10. Diff and tranny braces
11. High flow cat or resonating mp
12. Single turbo

Time frame-wise, I would like to do at least do 1-4 this winter/spring, 5-8 I am unsure when, and the engine rebuild in a year or two with the turbo following an unknown time after. I am a diyer and I enjoy learning and working with my hands, so most of these will be done by myself.

Thanks in advance!

 

uh...wow..Good list.You got a hold of some good plans!

*my Recommendation?..get a GF with MONEY..haha..!

 

"GF with money" so funny... but true... cause the GF with out money will wait for you to sale the car after you do all that... lol
I am sorry, but i couldn't help it.

Good list though..

 

Well no GF, hence having the money to do some of these things. Are there any smaller items I should add (like a HKS twin power) and if so where in the list?

 

Add a Water temp gauge and oil presure gauge. The twin power I would put it anywhere after you install the power fc.
Do a lot of reading on the single turbo build section. All the parts that you choose have to work together to deliver 500whp. Personaly I don't have 500whp nor I need it.
Make sure you engine is build by someone who know what they are doing.
Good luck

 

Thanks for the advice. I'll add them to the list. Is the stock oil pressure gauge reliable enough if mine is still working or should I get an aftermarket one as well to have a back up?

I've been jumping around so much from reading about how to replace my clutch to pulling the engine (for little bit I was thinking about doing the rebuild now) to injector sizing to how to tune the adaptronic ecus that didn't think about checking the single turbo section. However, by doing so I've already learned the the supra fuel pump wouldn't reliably be enough for 500whp and that something with a bit more flow would be better.

Yeah I know 500whp is bit over kill for what I need but I like to have a long term goal to work towards. If that goal changes, then that's okay.

 

Fuel pump is one of the things you have to look into and decide, dual in tank or outside more capable pump. I have FFE fuel rail with ID 1000 and ID 2000, great quality 0 leak and perfect fitment from the first try.
You have to know what part you want and why if you are going to do it yourself. Example: what turbo kit (turbo size) you are going to run? And why?
What you want the car for?
I know the experts in here can give you a more detail choices and point you in the right direction, just be inform on what are you doing so you know what they talk about when they do.
I know that howard , Aron, rotaryevolution, sgtblue, eliot, and many more have excellent knowledge.
Post what you end up doing.

 

Looks like you have a nice relative low mileage car and your list is generally well thought-out. But since you've asked for recommendations I'll throw this out...
Making a 500 hp FD is not easy or cheap, but it can be done. Making a 500 hp FD anywhere near reliable is VERY hard and VERY VERY expensive. It's also all but unusable power for the street and there are many long-time owners that regret doing to their cars what you're proposing to do with your's. Drivability, refinement and all-around enjoyment of the car are chief complaints. And when coupled with the money spent and constant tinkering needed to maintain it....
My recommendation is to do all the repairs and reliability mods on the car and seriously consider changing your goals from what will largely be dyno bragging rights to a fast well-handling and reliable car.

Some threads that might be worth your time...

Yeah the FFE fuel set up kit was exactly what I was thinking. I haven't looked at too many turbo kits yet as that is the last thing on my list and it'll be a while before I get there. However, the BorgWarner EFR kits do look interesting. Mainly I have been trying to focus on reliability mods and some of the things I'd need before making more power (ie ecu and fuel). I have read quite a few of howard's threads (where I got the idea to run two stock oil coolers). Should I do a build thread you think? Would a build thread from a complete noob be interesting?

I've seen the two bottom threads before and have read the last one a few times (that is where I got most of my list from). I guess I'm torn on what I want in the end still. Currently, I like having my fd be clean, functioning, and (for the most part) reliable. I plan on keeping the a/c, power steering, a stockish look, etc. I'm going to work on the reliability mods first starting with the duel oil coolers and silicone vacuum lines and then work down my list. Should I move the tranny and diff braces up on the list? I was thinking that I wouldn't be making that much power to need them until I went single turbo, but it'd be better to be safe than sorry.

The other half of me does want more power though. Like I said, I agree 500whp is a bit overkill for what I need and, honestly, my measuring contest is only between an '02 WS6 and an '04 SVT Cobra (friends of mine for the past 20 years). I currently only street it 2 or 3 days a week during the spring and summer, but it would be nice to take it to the track a few times a year. I guess I just need to tone down my power wants to match closer to my needs (not an easy thing to do).

So if I change my goal to the 375whp mentioned in Fritz's thread, drove 2-3 days a week with the occasional track day, and kept up on the preventative maintenance, do you see some other reliability mod (or just a good mod in general to do) that I am missing from my list?

Btw, thank you both for your input. I really appreciate it.

 

If you make a build thread be sure some guys will question some things and advise other, but I would follow it if you do it. I just like to learn plus I didn't made one when I did mine and I chose every single part that went into it and change some after.
As far as you power goal 350-380whp with efr turbo kit it's attainable and you don't need much psi. The Efr are great turbo, If I had the money that's what I would do. I have s362sxe and I it's awesome, I can't imagine the response of the efr.
A 360whp fd on dynodynamics dyno will be good enough to keep up or even beat that cobra with bolt ons, " power to weight ratio".
Keep a good maintanance of the car mean while you acquire parts and more knowledge about the set up you want.

 

*Metal AST or delete
*Larger metal radiator, Fluidyne or Koyo N-flow are popular
*S5 FC thermoswitch for the fans. Lowers threshold temp to 96 C. from 108 C. (is PnP)
*Maybe it goes without saying since you're going single but delete emissions, including double-throttle.
I'm not a tuner, but...
*Not sure how much use an AFR gauge will be.
*MAY need ignition amplification

 

I guess missing from my list of current upgrades is a radiator, intercooler, and 185F fan switch. As for emissions, the only one removed is the AWS, but I plan on removing some of the others once I upgrade the ECU and as I replace vacuum lines. I do need to read more into this topic though.

I was going with the AFR gauge per https://www.rx7club.com/single-turbo...gauges-581760/ and if I went with the Adaptronic ECU it would be useful.

I do feel better about my list and new (and more reasonable) goal of 375whp. I suppose I can start my build thread with installing the new clutch (hopefully this weekend) and go for there. Thanks again for the input and recommendations.

 

The only thing I will recommend for an ic on a streeted car is that you NOT go Front Mount. Guys say they've have done it w/o issue but all you're doing is throwing a big heat-sink in front of the radiator. It also requires fabbing, and compromising crash worthiness. And exposure to slow animals and road debris. Vmount...IMO, would be the way to go if you have the budget. But there are good stock mount options, even for a single turbo.

 

Currently I have a Greddy/Trust SMIC from Pettit that I figured would do the job for a while longer. I did some looking into vmounts but didn't seem to find any except for the KS vmount that would allow me to keep ac and a full size battery without relocation (which I then couldn't find anywhere to easily obtain it). Any recommendations on vmounts? I think I've flipped through most all of the threads in the top search results but didn't see any others that wouldn't require a lot of deletion/relocation.

 

Most of the v mount intercooler need some items to be relocated. You would be lucky if you find a plug and play set up and most likely it will be top $$$$.
Try this, type rx7 fd v mount intercooler on google, then on the top bar go to images. You will see a bunch of pics with v mount fd set ups. Go to a pic of interest and go to the link and you will find the post. The pic gives you better idea that reading hundreds of pages.
I had est front mount, which its useless for florida. I chopped up the piping and did my own home made v mount type.. lol and had to move stuff, but it's duable. I am happy with it, no more hight Temps for my baby.. lol

 

here you go..
It's up to you...

 

If you're looking to expand in the future power wise, I would invest in a nice fuel pressure regulator and work it into your fuel system. It's a must when switching up pumps and injectors

 

Yeah I may just try and come up with my own vmount set up when that time comes. Something that uses the ac as a splitter like in some of those pictures and allows me to use a smaller battery (as I don't want to relocate it to outside the engine bay).

Currently, I'm planning on going with the FFE fuel kit which comes with mini fpr. I need to do some more research before I fully commit to that but so far I've only read good things about the kit.

I'm hoping to get some time to start my build thread this weekend.

 

Can't wait to follow your build thread, should be interesting.
