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

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.

ok here are few more pics
just a picture of my motor so far where i am

here is a pic with hks twin manifolds that got me thinking about going twin turbo

here is a picture with my hood closed without that ugly tech2 hood.

here is the radiator that i am getting ready to mod
Attachment 716110
modding my power steering pump for fitting welded on hole shut and welded a -6an on the other so i can run braided lines for a nice looking setup

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?
