Id rather see it happen in an actual supra if it ever happened, a toyota engine in a nissan is a disgrace to nissans. I like toyota's but keep the right brands where they belong!

RB26>2JZ

You cannot be a rational person if you look at this and still think that it is a disgrace.

Also the worlds fastest 1/4 mile 240 is duy's 2jz s14 ^_^

though duy's may soon be out ran by this in a 1950 lb s13 coupe

Just wanted to update the thread.
Check out the new mod list in my intro post.

We decided to scrap the twins, and instead went with a GT4088R.

This turbo should make the 700whp I am shooting for, and we'll know in the next few weeks.

The block is finished, and we are just waiting on OEM Valve Seals before we start on the headwork.

Looking forward to dynoing the car in the next 4-6 weeks.

cruisnhard · 03-23-2007, 02:24 AM

Holy crap, what is up with that engine. I like it. I would love to see it in the car. Also yeah where are the pics man.

underground · 03-23-2007, 09:57 AM

I'm going to the shop this morning, and will take some pics..

I know everyone is curious to see, and I aim to please.

Without a doubt, the biggest aggravation with my 240SX has been breaking axles.

I have in all seriousness replaced the left side at least five times, and have broken on the line at the drag strip twice. This is quite embarrassing to say the least.

I noticed that Duy (1000whp 2JZ S14) and Mark (Mazworx T88 S14) have both ran the Mazworx axles, and they have held up to multiple 8 sec passes without breakage.

"The Mazworx 32 spline outer joint and upgraded inner joint will give years of lasting service. The Kit includes driver and passenger axles, new hubs with ARP Extended Wheel Studs already pressed in, and the Mazworx Inner Joint adapter to make all the parts a bolt on affair."

Considering my car is a street car, and I'm shooting for the high 9's, I figure this setup should hold all I can throw at it.

They are $1799 plus shipping, but worth their weight in gold. 1 Year Limited Warranty.

Here's an image of the pieces included in their kit:

DriveShaftShop does offer their own version ($1599/ rated for 900 HP), but it isn't nearly as complete, and only replaces the axles themselves....which is only half the problem in that car.

If anyone wants to post up other manufacturers, I'd love to get a list going.

To my knowledge, these are the only two making upgraded setups for the 240SX.

mrbojangles · 03-29-2007, 02:44 PM

no pics?

underground · 03-30-2007, 07:13 PM

There's not much to see.

The block is finished, but the head is at the machine shop.

The car is filthy and has been sitting at the shop with a tarp over it for the past two months.

I'll be posting photos when the motor is back in the car, and is more presentable.

underground · 04-19-2007, 03:23 AM

I wanted to post some pics of the build on my car to show it's progress level.

I had to order custom motor mounts for the car, and they should be here sometime later this week.

Right now, it appears like the car is 2-3 weeks from being completed.

It would be much sooner, but I am still waiting on parts to arrive from Japan.

mrbojangles · 04-19-2007, 04:17 AM

Yes, I kept the ITB's, instead of going to a Q45 or larger single.

I may switch down the road, but for sub 1000whp, I'll keep the motor with the ITB's.

mrbojangles · 04-19-2007, 11:18 AM

interesting.. who makes them?

Nissan....

The GTR has ITB's from the factory.

mrbojangles · 04-19-2007, 03:15 PM

iteresting lol never knew that.

and i'd figure no matter how much hp you are looking for, the itb's would breathe better than a single 90mm tb right?

I dont know if I would say that, as the restriction is at the plenum inlet.

Which on that car is around 75mm I believe. I need to measure it to be sure.

You could always run a billet 100mm throttle body with custom intake manifold that I'm sure would improve airflow.

But for the HP goals I am shooting for, it's not cost effective.
