96cxt build

[96cxt]

Hello everyone. I have owned my 92 for about 12 years now and just decided to start my build thread.

Car's 1st year consisted of the following (sorry no pictures)

Stage 1

Volk GTV 18/19
D2 complete coilovers
GT Shrine front lip
DC sport exhaust
Top Speed Headers
Porting the intake manifold http://www.nsxprime.com/forum/showthread.php/118430-Porting-the-stock-Intake-manifold-(my-write-up)
Big bore TB
Removing the VVIS
Stock clutch

Car Dynoed at 270whp with no tuning.

Stage 2

BBSC Supercharger 8psi pulley
GTLW exhaust
Welding bigger collectors/flange on Top Speed headers
Test pipes
Replace clutch (stock OEM clutch again - Twin Disc)
AEM EMS series 1 (2nd gen)
Water to air cooler

Car Dyoned at 411whp

After having the Supercharger for almost 10 years, I decided to change things up.
So I sold the Supercharger kit and bought the Twin Turbo kit with the VATN turbos. If you are not familiar with this turbo kit you can search with lots of details available online.

This thread starts from my stage 3 set up of the turbo kit. I decided to do a complete build with removing the engine and doing a clean up and all the services while I have the motor out of the car. Here are pictures from the pas week of me removing and cleaning up all the parts.

I pressure washed (electric one from Harbor Freight $70ish) the sub frame and the engine. I used simply Green solution only.

I will post pictures as i have updates.

Looking forward to your progress. I was just thinking of you this morning. Glad you posted.

Og!

Og!

Hey JP! Hope you are doing well in the new world order

Finally all the parts came in.

Replaced the following:

Timing belt - The old one has less than 10k miles but was replace about 7 years ago.
Cam seals (x4)
Crank seal (oil pump side)
Cam plugs

Here is a tip for anyone that is going to tackle the timing belt on their own.
Before removing the old timing belt, set it to TDC (piston #1 ) and mark cam pulleys and the belt.
Remove the belt and trace the marking onto the new belt at the same location so when you install the new belt you know exactly where the timing belt will sit. Factory has the markings for TDC but this takes the guess work out while installing the new belt.
Another tip - The cams oiling plates on top have holes and the cams are notched. You can put a long 10mm bolt through the oiling plate to keep the cams from moving when you are installing the new belt.

Here are pictures...






With new belt





Here are pictures of the Top Speed headers. 7 years ago I had welded bigger collectors (2.5") and flex pipe since I was running the BASCH Supercharger kit. If you are running a supercharger or turbo, this will help with more exhaust flow.
Over the years I have had people ask me for pictures on these. Here you go!




Next step is to do the valve adjustment and check the friction discs for wear. I am running a stock OEM twin clutch which was replaced 8 years ago but has less than 10K miles. It looks great but I will measure to ensure they are in spec according to the service manual.

Also gonna send my valve + manifold covers to get red powder coating done. Looking forward to getting everything done by next weekend.

Awesome build, can't wait to see it with the new kit!

 

[96cxt]

The engine is back in the car, did a warm up cycle to ensure no oil or coolant leaks.

Did a compression test before installing the motor back into the car.







And a pic of the motor back in the car. Still have to flush and bleed the brake fluid, clutch line fluid, install the air box, and a few other misc things.

Wow, congratulations. Looks like a huge project. Always nice to have things go back together.
Hope you didn't have any extra nuts and bolts after the install.

Update:

The car is back together and I've put on about 120 miles on it just to ensure there are no leaks or any other issues.
Here are pictures of the car after a wash and wax

Very cool . How do you like the polycarbonate hatch & scoop? I've thought about something like this for my car if I had a FI setup with a top-mounted intercooler or something, but I think it's cool regardless.

Is it ok if I like the wheels on the little one more:wink:

I have had it for years now. I got it used from another member. It worked out great for the BBSC supercharger kit I had, it helped keep things cool under the hood. Living in Houston, we see +90* days and you could still touch and hold the intake manifold after coming back from a long drive.

Since I'm going twin turbo, I am trying to figure out if I should get the water to air intercooler with the cooler plate sandwitched inside the intake manifold or should I run an air to air intercooler under the hatch scoop.

As long as it's only the wheels and not the whole car :tongue:

So i finally finished up the turbo install and completed the intercooler.
Hoping to get the tuning completed in the coming weeks. Im not looking to make more than 380 ish whp. These are small turbos and should have good low end power.

Currently has a street tune before the intercooler was installed and i love the quick spool up and useable power at normal driving.
will post dyno sheet and video once completed.
