here is my 99 spec bumper put together and ready to get trimmed to fit over the intercooler.

 

finished my down pipes yesterday 2 2.5 pipes going into a 4inch pipe i made. now i need to use 4 inch aluminum all the way back. im going to be using my hks 4inch titanium muffler.

 

So did you modify the subframe and drop the rack (solid mounts or hinson kit)? Do you think the engine needs to be lowered less with Scoot hood compared to oem?

I am asking for a friend who is also trying hard to avoid tech2 hood. He modified the subframe to keep the stock hood but now his engine sits too low. Then he installed 19" wheels to raise the car up a bit but that didn't help. He's ok with scoot hood if he can close the hood without lowering the engine too close to the ground.

 

scoot hood give a lot more room.

 

I can't say for the Scoot hood, as I've never had or seen one.
To fit the 2JZ under the stock hood, you must lower the subframe and steering rack at least 2". (This assumes 16" wheel with a 245-45-16 tire.)

Compound that with lowering the car with lowering springs or coil-over shock suspension and you determine your tie-rod angle.

Total suspension geometry change is between 3.5 to 4".

Bump steer correction must be greater than the drop dimension through precise measurement, and is already greater than most kits limitation.

Does this mean the car will be unstable?
Not necessarily.
Some tie-rod angle compensation from a dramatic drop like that is better than no compensation at all. But when it comes to a performance car going over 140mph, I wouldn't want to take a chance the toe in/out moves when you load the suspension.

Just my take though.
After my build is done, I'll make another and test it.
The biggest fallback in my opinion would be the new rack is 4" off the ground, which seems very low.

 

Thanks for the replies Turbotito and MK3Brent.

Turbotito, ok scoot hood gives a lot more room but did you have to lower the subframe and rack, how and by how much (inches)?

 

what are you talking about only 4" off the ground

 

With a 1.5" suspension drop and 16" wheels, your subframe will be 4" off the ground.
I didn't stutter.

 

oh yea, you right. forgot about the whole" aftermarket suspension set up".. 4" is fine man! hell my sr20det s13 i use to have the sway bar was like 1 3/4" off the ground lol..oil pan was like..idk 3 or something at most lol

 

i doubt anyone putting a 1j/2j in their car is going to keep the 16" wheels.
a drop is likely though, but combined with stiffer springs up front for the added weight, i think 4-5 inches clearance is still quite a bit.

i guess it all depends what youre used to. my old 383 stroker transam headers only had about 3 inches of clearance and i drove the hell out of that thing everywhere.

you just cant drive over speedbumps like a maniac, you have to actually slow down .... oh and quick reactions to avoid upcoming potholes is good too

 

Wheel size was just for reference.
The tire has more defining numbers than any wheel.. It was just easier for explanation purposes.

Back to the thread now.

Good work, T.
You might not be the only 2J with a scoot hood now.. (Got mine last night.)

 

lol but fill be the first scoot hood twin turbo lmao.

 

ok finished reshimming my gsc s2 cams .010 on the intake and .012 on the exhaust. now i just have to degree them.

a little more bling

a lot of bling

 

Is there no other alternative to replace the 90 intercooler coupler elbow that a lot of you guys seem to be using?

That's such a sharp bend in the air flow, ya know?

 

This one is also one of my favorite builds.

Keep it up, man.
I can't wait to see some videos of your FD.

 

its a 3 to 4 inch man. NO MATTER WHAT IM GOING TO NEED A REDUCER ILL TELL YOU WHAT THIS WHOLE COUPLER THING IS GETTING ON MY NERVES MAN NOT JUST YOU BUT EVERYONE. WHEN IM DONE AYONE THAT HAS A PROBLEM WITH THE COUPLER LET GO DO SOME HIGHWAY PULLS AGAINST EACH OTHER THEN COMPLAIN ABOUT IT AFTER YOU GOT TIRED OFF LOOKING AT MY TAILLIGHTS FORM A DISTANT. I CAN BELIVE THAT THATS WHAT EVERYONE IS COMPLAINING ABOUT. EVERYTHING BECOMES A RESTRICTION A A CERTAIN POINT. IN THIS CASE THE CAR IS TURBO CHARGED. THE AIR IS GOING TO BE PRESSURIZED INTO THE MOTOR . THIS WOULD BE A BIGGER RESTRICTION ON A N/A CAR. I DONT PLAN ON GOING TO THE POINT WHEN IT WILL BECOME ONE BUT IF I WANTED TO I COULD BEING THAT MY MOTOR IS BUILT TO HOLD 1400HP. BUT WITH 800RWHP THERE IS NOT GOING TO BE TO MANY CARS THAT ARE GOING TO BEAT ME. IM NOT TRYING TO HAVE THE FASTEST CAR BUT I DO WANT SOMETHING THAT IS DIFFERENT. AND THIS CAR IS. AND ITS NOT DONE IM GOING TO PUT SOME REALLY CRAZY SEATS IN THE CAR THAT BOTH ARE 12LBS COMBINED IM TRING TO FINISH THIS YEAR BUT WITH THE THINGS I HAVE IN MIND ITS NOT GOING TO HAPPEN. ok im calm now please if i keep hearing about this damn coupler again im going to go crazy lmao.i can sit here and complain all day how a rotary motor is garbage but i dont.

 

thanks a lot. ill have videos of when i turn it on. the driving part i dont know if ill have the rest of the car done. there is about 10k of stuff that i want to do to there car.
seats
big brake kit
interior
fuel system
and paint
and whatever else that i decide to do along the way. lmao

 

Nice welding my friend! Very nice build and very innovative! I love the twin turbo setup! Very nice! I'll be following along at home.

lol

There's no need to spaz out.

I'm a 2JZ-FD as well, friend.

It was a valid question, is all. Not my fault I'm only the 1,000,000th person to notice..

I have no doubt your car will still be fantastic, though.

BEST OF LUCK TO YOU ON YOUR BUILD, I'LL BE WATCHING! AAAAHHHHHH ALL CAPS!!!!

:]

 

Yoshi, did you miss my post about the velocity calculations?

seems like a pretty legit reason to me

your the only person to continue noticing, and noticing, and noticing, and noticing, and noticing

 

and ignores my proof of concept.

 

Man this thing is going to put a lot of supras to shame. Everybody is switching to huge single turbos

glad to see you're going twin ftw

 

Dang.... that things a Beast...

 

Only thing about the twins though, is the sound.

Sounds completely different than every other 2J with a single.
Sounds V6 like.
