bad ass 2jz twin turbo rx7 fd build
 

well i just picked up my new project a 93 mazda rx7. the car is completely stock i almost feel bad ripping out the motor but then again i dont lol. well im going to be taking my fully built motor from my sc300 and stuffing it in the place of the weak 1.3L no torque making Wankel motor. well here are pics of the car.

Ok I have some updates and pics so here is a list. I got my wheels and brakes powder coated the wheels are two tone black and the clipers are red. I installed all black jnterior just need carpet and floor mats. I also had my friend Danny rewrap the seats with new red covers to make the car pop inside. I installed the tech2 sub frame that I will be doing a mod so the hood clears. I installed my built motor with custom 9.5:1 cp pistons with lataral gas ports and upgrade pins swinging on some carrillo HD rods with carr bolts. The block has arp hardware and callico bearings block was lined honed as well. The block was but by lee at the lad in long island Brian refferd me to him. I also installed mu fully built head that was porter by me. It has all the goddies 1mm oversize valves dual valve springs and retainers 5 angle valve job and valve guilds everything from fearra. The head is sandwiched with a cometic 1.4mm h/ and arp head studs. I also took my r154 to get rebuilt and upgrade with all the upgrades that driftmoton had. The thirst washer, 1st 2nd billet fork, the bearing case plate, both shifter bushings and all bearings and syncros

im going to use my scoot hood im going to modify my sub frame a little bit. i love my hood way to much to put that tech2 hood. im going to make custom soild mounts and drop the rack about a inch give or take and get the hinson super cars bump steer kit they are adjustable.

here are pics of my 1jz flywheel act 6 puck and xtream pp with are flywheel bolts i just installed today.

here are some new pics
my custom radiator support i made
Attachment 716104
a little more more work done to the motor a/c and power steering got put on today. first time i ever use them.
and last i finaly got my d2 coilovers thy are really light i was surprised. they are 32 way adjustable i had them on my sc300 and were great so i decided to get them again.

i took all the pics form my supraforums thread and copy and past on here because they band me over there for trying to sell a turbo manifold that i made. if it was a ebay crap manifold there would had been no problems. anyway im waiting for some more parts to come in.

^^rough forum

Do you have any pictures of what you might have done to the subframe to get the hood to close?

I'm a good bit into my swap, and noticed you had the Tech2 subframe with a scoot style hood closing.

Seems you would need at least 1.5" shim to bring the engine down to do this.

yea im working on resizing the pictures thats why some are small and some are big

where in NJ are u?

bergen county

my powder coating was done by billy he is a really cool dude man. his number is 201-889-1873 he also has a good turn around time.

Dang.

I'm jealous.

That looks way more B.A. than my 2JZ swap...not gonna lie. ^.^

thanks i believe i have the second ever twin turbo rx7 fd. around right now. im second to the original supra7 that SP engineering did. but first with 2jz twin turbo scoot hood lol. i just welded up my downpipes. they are 2.5 inch each going in to a y-pipe that i made and hooks up to a 4in electric exhaust cutout. i also had to make a hole in each manifold so i can run external waste gates. im run 2 tial 38mm mbs gates. the new style is so much smaller.

The engine bay definitely looks clean in the pics...but I have to say that the 90-degree elbows concern me in regards to air flow..

Sharp bends like that, especially in a coupler, are never really good.

Maybe you could re-do your intercooler piping a little? Just a recommendation..

Impressive.

Nice to see more 2jz FD's pop up in NJ, especially Bergen county.

Kinda like the welds inside your intake manifold? :nod:

I'm just pickin' :lol:

if you noticed when the air comes up its ot hitting a flat surface on the coupler. the coupler is rounded so when the air makes its way up it has a smooth curve to flow threw.

^^^ lmao :lol: and by the way no i did take picture of what i did to make the hood close.

For what it's worth, I've done a flow calculation on varying geometry which includes angles.

You may be surprised that the changing ID from source to termination causes more non laminar areas than direction changing while in a pressurized state.

nice looking swap!

Nice I can't wait to see the finished product

Here is a quick calculation based on difference in geometry.

Note the velocity change:

gah that's a clean 2jz D:

how much hp you think you're going to be making?

im looking for just 700rwhp im not going for crazy numbers in this little ass car lol.

Have you been building this thing outside in the snow?

-Austin

yea sometimes when i have crap to do ill go play with it but lately no because way to much sow just been buying parts to have them ready so when i can go back out and play with my toy.

what ECU are you using?

well my top 3 picks are
1. proefi
2. aem v2
3. haltech platinum sport 2000
but i want to proefi because it works great with e85 it can adjust its self according to the amount of ethanol. so you only need one tune. i made 780rwhp at 22psi with a stock block 272 cams and valve train upgrade with a 80mm turbo. i cant wait to see it now twin 54mm turbos 9.5:1 compression 274 cams with more lift then the hks 272 and a fully built head and block plus 600lbs less

update here is a pic of the twin turbo setup with custom 2.5 inch down pipes that i made. i also had to add waste gate ports because the manifolds were for internal waste gate setup. i made the downpipes so i can disconet the v band and take off the turbo with downpipes annd manifold all together. it will make it much easier to install and uninstall.

ok here are the turbos on the car all polished up already.

Nice man.

Please make video of the end result.

Love 2jz's to death.

I lived in Bergen county for like 10 years... just moved to Rockland -we have to get together and compare our beasts.

I'm LS2 swapped.

Looks like yours is coming together nicely.

yea that would be cool ill let you know when im done.

Mine is apart right now getting rebuilt. I go to Kaztech in Hackensack for my engine work.

ok few little updates.
i heat wrapped my downpipes and sprayed it with that black heat wrap spray.

i also did all my intercooler piping just waiting for my 2 new tial Q blow off valves to come in so i can weld them on and send some stuff to get polished.

Looks amazing, man. My only gripe is that 90-degree intercooler piping elbow you got there. That's a pretty air-restrictive bend to have in the IC piping...

the car will still make my goal of 700 to 800rwhp with that its really not a big deal. people need to understand that certain things become restrictive at certain boost or power levels. for example a 2jzgte intake manifold starts to become restrictive at 800 850rwhp. same thing with cams turbine housing and so on thrust me when i say this is still going to be good for 800 plus horsepower before it even comes close to playing a factor or a restriction. i build my cars according to the power levels that i want. its like would you buy a weldon 2345a fuel pump thats good for 2400 hp on a 500 gas powered car. that would just be stupid. a pump that is good for 700 hp would be ideal. same thing here im am not looking for 1000rwhp+. its like taking a 13b and getting a full blown race port on stock twins. you dont need a full bolwn race port because it makes no sense. same here i dont need to replace because its not going to hurt my number or become a restriction till way after my power goal. so why do it?

See post 22.


FYI, so you don't need to break out the calculator. My calculations were done to 90 lbs/min.

ok i got my radiator shroud and fans in today. i also put pieced together my oil return.

still waiting on my blow off valves

you are gonna love the GSC S2 cams, but i would highly recommend not running those Venem cam gears, they only have 4 bolt tightening pattern, i have heard of these along with AEM and HKS cam gears slip timing. i would look into Titan Motorsports, Fidanza, Unorthodox Racing, Greddy or Nitto. all of these companies make a 5 bolt tightening pattern which will not slip timing

thanks, but i already made 780rwhp on the cam gears with a th400. thats over 900rwhp on a 6 speed. i never had a problem with them but i did with the aem ones like 10 years ago. anyway here are some new updates

I finally got my blow off valves.

It looks great, but that super huge 90-degree bend coming off the throttle body still really bothers me, man..

Did you not have any other option for routing the IC piping?

well i put my car oh hold to step it up and buy a new welding machine. i was using a miller econotig but i was really limited when it cam to a/c welding. so i went and got my dream machine. it can weld on 120v and tons of functions. its the miller dynasty 200dx. tried it out this morning this thing is amazing and its only 47lbs
