I am trying to get a special sub forum for Frankenstein (engine) RX-8's, which was agreed to (I think) but is not happening yet.?

None of these belong in Tech Section

nycgps is a bit of a whiner ;-)

some of that car is totally weird...but so much of it is realyl novel, especially the transmission is amazing, really cool build!

only in russia....

i dont see anything special about it that's all, all u gotta throw is enough $$$ and it will work.

give me whatever money I need I can build you whatever you want, I will even be able to make a Ferrari running with a Geo Metro engine.

How much drivetrain power lose do you have? Should have just bought a 6 speed Supra to begin with and call it a day.

Ugh!

bunch of haters in here, to each his own, let him do his thing. I know i wouldn't mind driving one

that's ******* awesome.

congrats.

i DD an awd car now and i have to say, awd is superior to rwd hands down. rwd is a bit more fun though.

good_s

thanks for everyone!

power loss in tranny isn't significant and equivalent to manual transmission (almost), just because here we have no Torque converter.

this tranny shifts very fast and it is a problem because of comfort.

have a look on my other cars: I've got Toyota Trueno AE86 with 2JZ and manual AWD tranny for example.

many photos you can find here: Toyota Sprinter Trueno GT40 2JZ Awd MT | TheDriveBook

and AWD gearbox itself How 2JZ 4WD MT gearbox is made? - Journal | TheDriveBook

we have experience with 2JZ 3,1L 272/272 and GT4088 2.0 boost for weekend and everyday driving on JZX105 with HKS clutch

tranny is still alive)) photos and description here: Toyota Chaser 2jz-gte 4WD, 5

I reckon you have done a great job.A bit of a clean up in the engine bay and youre done, do you plan on Dyno-ing this ? Enjoying the QLD weather compared to Russia

Props on what you did and all but not a fan of how the car looks. Always wondered what AWD would feel like in our cars.

So your utilizing some form of Clutch Flite system?

With a 3.1L, VVT & 4088 I would expect power to be around 650 Crank HP & 500 AWHP max?

I can also assume this is a 2JZ-GE VTT? Not a GTE

good_s

regarding power: i assume its much more than 650hp, but just dyno graph could
confirm it.

regarding cylinder head: it is hardly modified GE head, it has ported combustion chambers to the equivalent of GTE head.
The benefit is that final head has significantly increased intake and exhaust tracts (and you can use stock toyota gasket to get 8,5 compression ratio).

will add photos of process and result later (need to find photos on my laptop)

good_s

ps: in Russia 2JZ-GTE VVT-i is more common than non VVT-i (old one)

Mr.Mango

Well with the size of the 4088, 650-700 is conservative without cams (didnt see a listing) but could probably hit 750 with cams... You might get a bit more bottom end torque from the increased stroke.

That makes sense regarding the head, you should have 8.5 if your using a GTE bottom end with standard compression ratios and using a factory HG.

Its very hard to even find VVTI engines in Japan due to low production numbers through 98-02 hence why very few companies made cams for them.

good_s

Yep, you right.

in my case (RX8 and Chaser AWD MT) we use 272/272 Brain Crower cams.

Ported head shows notable extra power. And of course bottom is GTE.

However GTE and GT cylinder blocks have no principle differences, just oil injectors. And these injectors we have put in the same way as stock.
RODS and pistons are non stock) we like CP pistons, some times we use colben shmidth.

i've got many info about combining different cylinder heads, blocks from 1-2JZ - GE-GTE. regarding compression ratio and other. if you are interested in smth let me know))

Mr.Mango

iTrader: (2)

Didn't know B.Crower made VVTI cams, interesting!

Ya just the oil jets, which some people tend to delete for some reason... which I dont understand, only a benefit.

I am in the process of building a 3.4L stroker right now with a 94mm Titan Crank, Carrillo's , CP's and all the goodies. RX8 is here to fill the 2-3 year void while that project is finished haha

Mr.Mango

iTrader: (2)

Have you done a AWD 2J in a MKIV? Many people on supraforums would be interested to see that if so

shazy

would like to see a video of this car running, personally not that bad looking either. Just remove a couple parts and you're good hahaha
NYCGPS, what's impressive to you then?

Mr.Mango

iTrader: (2)

I want to see all wheel dyno numbers!

Paco664

impressive build... and amazing fabrication work....

ignore the ones shitting on your work...

good_s

thanks a lot!

now i'm in Russia again and will prepare my car for running.

will write news here))))

spooln7

thats crazy! good job!

T4XJS

What happened to this car then..
Did it get finished..
I'm thinking about converting my RX8 with B204 rwd to 4wd now..
B234 engine cosworth 4wd box etc..

Good_S, we're waiting for some videos-forget about the pics!!!

MrRogers

sorry about all of the haters its just because you switched to a piston engine, had you chose another rotary they would be jizzing themselves. that's amazing man do you have/are you willing to share/sticky the specifications and measurements on how you built that trans? maybe all these haters can use it to build an awd rotary one day
