Hey guys,thought I'd share my engine build with you. My car has been for sale for ages & just couldn't give it away! I was going to do a PP turbo in a RX3 Drag car of sorts,but it looks like the FD is here to stay,so I'm thinking bridge port at the moment & maybe a centre bearing crank from Rohan at Xtreme Rotaries. I already have a set of single piece 3mm NRS ceramics. All the engine machining will be done by Rohan & the engine will be ported & assembled by myself & Dave at GT Auto garage. The engine made 450hp at the wheels on 1.2bar @7000rpm with a HKS T51R spl. The ports are standard with the only mods being 3mm steel apex seals,clearanced rotars & Xtreme Rotaries stud kit... The engine came out & appart today. Pics shortly...

here's some pics...

Hey guys,my engine,clutch,fly wheel etc is at Xtreme in Melbourne for machining & balancing. I got some pics from Rohan of the manifold/throttle body set up. I hope I dont get into trouble for showing the world. Each butterfly is 48mm X4 which is a fair way bigger than the modified stock one I have which has one 48mm for both primary's. Tell me what you all think,it's very Porto Rico spec :bounce: :bounce: :bounce:

dave20bpp

Well all the bushes are in finally & all the arms back in. What a **** job,I know why tuning shops charge so much to do it. A big thanks to GT Auto garage for letting me used their press

Here's some pics,before & after

Just a quick up date. I got a set of front fenders off the actual FEED touge car in Japan! Got them for a good price cause they're second hand. So I can say that my front guards have run 59secs at Tsukuba :bounce: :bounce: :bounce: heres some pics....

Bout time for an update as Dave has been on my bloody back lately. Porting to suit Rohans manifold is done & the engine is now assembled. Here's some pics to start with....

dave20bpp

And here's some pics of the engine going together. Rohans machining is just perfection as always which makes assembly a dream.

Here's some pics of the manifold Dave & I have been working on. It turned out very well I think thanks to Dave & his awesome welding work :mrgreen: :mrgreen: :mrgreen:

Hot !!

what fuel are you going to run ? Still planning to run a intercooler ?

wow, lookin really good man

everythying looks great. i gotta ask tho, what kind of water pump pulley is that on there? it looks ribbed.

did u convert to a push type clutch? any advantage? are u using the stock tranny with the OS giken converter? or something else...

the manifold is interesting.. reminds me of the V8 carb setups... I wonder how it performs...

I love the sound of the T51-R.. only problem is the turbos are so damn fragile and break so easily.. they cant take abuse much..

Just out of curiosity did you change the compression on the rotors? Reason being it appears that the pockets have been machined if not it might be just the camera. Great work can't wait to hear and see a video of it running.

wow! very nice stuff there! congrats. i, too am interested in what machining was done to the rotor recesses. i can see that the overall weight was reduced, but there seems to be something unusual about the recesses ... share if you can, but if you can't, i understand. it's part of the game.

anyway, i'm very impressed with the manifold/wastegate setup. the engine is a beauty, but i think your exhaust setup is it's crown. perhaps its just the jealousy of knowing i can't weld yet. can't wait to see your numbers and hear about the boost characteristics. enjoy it, man.

you guys are very observant was wondering if anyone would notice, the rotors are a real trick bit of gear they are series 5 rotors as they have more meet to machine, and yes you are right the combustion chambers have been cnc machined to lower the compression ratio to 8:1 you may also notice that they have been lightened and if you look at the photo again they have been re-profiled by this i mean they have been machined into true shape and it is quite interesting to see where the cnc takes meet off and where it leaves it one, just shows the imperfection from factory.


if anyone wants to know more about these rotors and price etc pm me the way the american dollar is against the Australian dollar at the moment it may be a viable option to get them shipped over that goes for any of the X-treme Rotaries gear.


cheers dave

dave20bpp

98 octane pump fuel on the street and C16 for race days and dyno stuff, and yes the it will still run a front mount intercooler.

dave

dave20bpp

yeah converted it to push type some time ago and started running the Carbon twin plate it runs a ATS @ Across adapter kit and run a OS Giken 5speed gear set

Not sure what you mean about the Turbo has never missed a beat.

Very nice! Rohan always does top notch work! ......Should make heaps of power. cheer's mate

I've never been very impressed by the factory rotors. I've always thought there casting could have been better. Maybe the fact that they are mass produced is there short fall. I always thought that somehow you could change the c/r of the rotors by machining the pockets just didn't have the know how of doing it. But apparently you guys have done it and it is great to see people out there continualy improving on things. Great build and those rotors are truely a work of art.

do u use 2 step? thats what usually breaks them..

at least with my friends using them on Rb26's and 2JZ's


either way very nice car bro

how is the OS gear set? does it make the car more difficult to drive at all?

dave20bpp

The Os Gear set is just like a factory box infact the hotter the oil the nicer it shifts

Wow, this is incredible. This is a true copy of the original E&J Throttle body. Is amazing how the top notch stuff made is strickly a copy. You want to see top notch go to eastcoastparts.com. The least they could of done is make some type of change or improvements but i guess they dont have what it takes.

Hey do you have any pics of the throttle body and intake manifold on the motor in the car? I dont think thats going to fit without any cutting of the hood or lower manifold.

SPEED_NYC

iTrader: (3)

anthony i don't think it will fit either, i know for a fact the E&J TB with the JW lower intake wont clear a fd hood.

anthony, if you're intrested in that intake or TB let me know i got a set comming in and its cheaper that the E&J/JW combo. it also comes in a semi perif configuration as well, no mods needed

SPEED_NYC

iTrader: (3)

look at what this guy had to do to clear the E&J set up, and he has a low profile hat on there
