I spent a few days toying with the idea of putting together a turbo kit for the n/a fc owners, this kit is however not completed, and nothing is set in stone. I am trying to offer the cheapest possible way to turbocharge a non-turbo FC. I do know ofcourse its not of the best quality, and obviously not the proper way to go about doing it. I already make a very high quality To4 manifold, and kit for both turbo and non-turbo Rx-7s, but lets face it, not to many Rx-7 owners can afford to do anything the proper way.



Key points:

Cheapest possible kit at the expensive of quality

Little know-how required to do this

Most bang for the buck



This proposed kit will use a factory 87-91 turbo and manifold with no intercooler, but water alcohol injection.

The EFI will remain factory, except for larger secondary injectors and an S-afc or some other fuel controller.

The factory intake system, main catalytic converter and catback will also be used. No tapping required for oil feed or return lines.



I have not completed this kit, I don't intent to spend any money finishing it, testing it on a car etc if there is no interest. As said before I can alter any part of the kit, I can even have the turbo hot pipe made out of a nice cast piece if desired.



I have made a nice sturdy spacer, that will not break over time. I intend to add some bracing to it, and also weld it inside and out at each flange. .128" thick wall tubing will be used, and I have 1/2" flanges on either end. It will require either longer factory studs, or the use of bolts and nuts. An additional exhaust gasket flange is required. I have aftermarket ones in stock.



I have not constructed the downpipe, but I already have the flanges, and I plan on making them out of 2.5" O.D. piping. It will bolt to the stock main cat.



I will have assembled oil feed and returns lines, made out of cheaper Earl's AN lines, SS rubber hose and CNC flanges. This will require an oil filter pedestal adapter for the oil feed line source. The oil return line will screw into the oil pan drain plug hole.



A water alcohol injection kit is required, $200 will buy you a basic kit here: http://www.coolingmist.com/categories.aspx...on=set&res=1024

This will require either I or youself to tap a the throttle body inlet to install a fitting.



The piping from the turbo to the stock TB can be setup as pictured if desired, it is by far the cheapest way to go about it, but by far not the best. I would supply a different piece of hose to attach the factory bov pipe to the turbo. I can have a nice piece cast that would have gentle bends and nice I.D. transition if desired, but ofcourse the price will go up.



These parts can either be supplied with the kit or you pick them up yourself:



1) Used s4 turbo, manifold, and associated lines/fittings possible stock IC lines/bov: $120-200

2) water alcohol injection kit $200

3) S-afc and 720s $400



Spacer, assembled lines, downpipe, and possible intake pipe I haven't determined the price yet, the parts alone are near $300. I'm not going to do this if there is no money to be made so probably atleast $300. I can also rebuild the turbos if desired, $275 if the price before shipping. We can also do any hyrbid upgrades too.



Now I figure if there is interest for this, it will be used on cars with a limited budget, running the factory powertrain and cooling system. I figure this kit should not be run at more than stock s4 boost, 5.5 PSI. The power increase should not overwhelm the factory drivetrain, cooling system, suspension, or the higher mileage used motors. All said an done the timing should be retarded several degrees, and a wideband used to tune the s-afc.



So is this worth doing or am I a retard https://www.nopistons.com/forums/pub...1047683561.gif I already asked my boss not to laugh at me..

dude, awesome... i was just about to post on here why do people buy a whole jspec motor and wiring harness and computer and all that for $4,000+??? why not just turbo the n/a... like all those honda people do? there naturally aspirated and they have turbo kits... cool tho, keep us posted. oh, and what the hey is a water/alcholol injection? i thought water was bad to inject into your motor. what is this for? oh, and the kit is definatly worth seeing as there are more n/a's than there are turbo's and of course everyone wants theirs to be turbo... i want to turbo mine but ive already done a full custom interior and dont want to rip it back out to replace it with a turbo wiring harness... so this would be perfect.

I would also like to add before this goes any further, I WILL NOT make anything unless I have atleast 10 people interested who are willing to fork down a non-refundable deposit. I know how much people like to talk.....

Let me first state that I'm not interested simply because you are about 8 months too late... I just recieved the final parts of my own 6port turbo.



However, I am curious to see how well this does... what PSI boost are you planning on running? Will you be porting wastegates for it?

you should just sell the spacer for the manifold, make like 2-3 or em at a time. maybe the hot pipe too, if theres interest

I agree w/ J9, it'll probably be better just to sell the spacer. The rest of that is fairly easy to put together yourself and I can't imagine many people would want to pay somebody else to source parts for them...



Secondly, not to bash or anything, but it is VERY dangerous to offer up a "low-budget" aka "low quality" turbo kit that will more than likely result in many a blown engine. This will cause most to have ill thoughts towards you and your kits.



Also, saying the spacer will last long enough is kind of hard is it not? how many vehicles are running the spacer? how much R&D has gone into it to ensure that it will last? Not trying to start anything, i'm just pointing out the fact that this is a "new" kit, so you can't gaurantee the parts will survive...not to mention, you stated yourself that you will be adding some bracing to it, which would imply the current design needs work...

1revvin7, You seem to be pretty good at making manifolds. Why not just make a LIM that clears the TII turbo?



But I gotta say, its pretty hard findind a TII to pick from. Not to mention finding a good working turbo and mani.

Ive got some ideas of how to make an affordable kit, just not a $300 one.

yeah just make a t4 manifold that fits the stock na intake! corky bell sold it as a kit in the 80's

If i get one do i get the yellow car beside it?



seriously though, Depending on the price since a 13bt swap with rearend/flywheel/cpu ect can happen for around 2k. and if you will give refunds if something breaks that had nothing to do with us installing it? like we get a turbo that has a small hole in it or something.

what?! are you nuts? a 13bt turbo swap with computer, rear end, and comp. for $2,000!!!! i dont think soo more like 3 to 4 grand and above

Or you could start with a TII for $1k more than a n/a....

Right, a common flange, internal waste gate, small quick spooling turbo, couple pipes to mate the exhaust and intake, and a haltech F5 AIC for fuel.

yall are kidding right?



1200 for engine, 150 for rearend, flywheel that depends on what kind you get. Tranny for 200. ECU depends on if you piggy back or do a compele swap so price will varry.



These are prices i came up with from asking people that were selling the parts.



Granted all of that is assuming you do the work on your own. It will be more of course if you pay someone else. But ive seen T2 cars here for 2500-3000.



i live in Tampa, FL btw.



Link to sale for TII for 2k

Granted a rotar housing needs to be replaced but it still cheaper if you do it your self.

that will give you a car one step away from the junkyard. Not many people are selling rear ends with halfshafts for $150 and not many are selling working transmissions for $200.

You also forgot a new hood unless your going FMIC which would then be more money, the fuel pump, the rest of the misc. parts. Your probably going to want some new gauges, at least a boost gauge, etc..

[attachment=34987:attachment][attachment=34986:attachment]

I could have gotten a s5 tranny for 200. But i oped for the s4 since it was the one made for my car. For 200 from the guy at maztech. Im sure you heard that place mentoined a couple times from the people around Tampabay florida area. He said he would give me a GTU rearend for 150, 400 if he installed it. There are also a few people around here in the rotary scene that we swap and trade parts. A friend of mine was gong to sell me his s4 TII motor for 500 but the rear rotar was busted. Around here thers always stuff poping up for sell. Therse a few people selling parts at Tamparacing.com (local race website/forum).



As for the fuel pump, i havnt looked at a price for one so im wont try to take a guess. As for the hood your right about 200 for one. But i was looking at going Carbonfiber so it will be more then 200.



Here is a guy from the area with engine/ecu/harness for 600. Granted it already sold but you get the idea. Link



But im all up for buying what the orignal poster is doing as long as its around 2k or so.





P.S.

That engine in those pictures are very very sexy. if it ever has kids let me know https://www.nopistons.com/forums/pub...IR#>/smile.png

a GTU rear end is not a TII

out here on the west coast you can get a jdm clip for less than 2k with the rear end.. so 2000 for the swap is possible..

i know. But i just want one with LSD. 88 GTU had it.

what about the driveshaft and the gtu rear end lsd or not is not a t2 rear end, i was looking at about 3200 for my swap and thats with a t2 drivetrain including trany and everything back, that was including some not needed but good parts like fmic boost controller , injectors and the basic swap nonsense.

I real conversion, that will not leave you stranded on the side of the road, will be well over $2K.



GTU rear won't work for the swap, unless you want to use all NA driveline, which is a terrible idea. The flange on the NA rears are much smaller than a T2's driveshaft flange. You could use a T2 tranny and driveshaft with the NA rear/halfshafts, but you would have to mill out the bolt holes for the T2 ds to bolt to the NA rear, which would leave maybe an eighth of an inch of metal on the outside, very weak.



Using a used block, used harness and ecu are dangerous as well since most of the parts will be over 15 years old. During my swap, I got a trashed motor for $1000 "JDM"...had warranty and all, but at the end of the day, I only got $170 back for it. I paid $150 for my tranny with $12,000 miles on a rebuild, it seems to be in good shape..so that's a plus. The rear end was $150, halfshafts were $125, driveshaft was $100, got a new motor for $3400. If you swap a S5 motor into the S4 cars, and dont intend on going standalone, you'll need to either get a chassis/dash harness and gauge cluster (which is what I did for $250) or go through mindless splicing. The S5 and S4 ECUs are not compatible with the interior. On top of all that, it was a waste because now I'm standalone, so yea..my overall swap alone was about $4k to $8k depending how you look at it. I easily wasted $2K on botched parts and going back and redoing things the RIGHT way...so be warned on those cheaper parts.

Lol, sorry revvin for jacking the thread...



...back to your topic, I do think if you could make a LIM that would clear the T2 turbo and manifold setup, that would be awesome, that would sell really well...



If you made an NA version, you could also make a T2 version allowing FC owners to use most FD bolt-on T4 turbo kits... opening a wide range of turbo upgrades for FC owners...

"Low budget" does not always mean "low quality" A lot of fc owners are cheap, or on low budgets, and cant afford expensive setups. I think 1revvin7's goal here is to make the best quality kit that is in the average fc owners price range.



That being said it isnt even worth the time to do the R&D on this kit unless a market that is willing to pay for it has been established.IMO

**** most FC owners can even afford to run the stock turbo. It really is a waste of time catering to Rx-7 owners, I'm going to work my way into other cars...

I agree, most FC owners can't afford much..thus the FC part...but there are some people (myself included) who would much rather build an FC then an FD...I enjoy the FC just a little bit more. An FD is a fun daily driver/weekend strip car...but if I'm going to tear an entire car apart and build it from the ground up, I'd rather do an FC..



What other cars will you move into...the lambos? Purchase an FD and start doing things for those, at least there is a good market on that end...and it's still rotary.

fd market is dieing too.

Rx8 then, lol...lets not start killing off the rotaries!! https://www.nopistons.com/forums/pub...IR#>/smile.png

my stuff was roughly that

well minus the engine rebuild

I am planning on turboing my n/a and i will be glad to buy a spacer. email me wade_carter89@yahoo.com
