Project 1500+ HP 997 TT

Recommended Posts

Well, it's winter again. That means it's time to take the car apart :)

 

The car ran beautiful this year with over 1000 HP but I've decided it's time to do a full engine build. The stock internals can only take 1000 HP for so long. I'm aiming for 1300 Wheel Horse Power.

 

Mods to achieve (1300 WHP) 1500+ crank HP:

-----------------------------------------

3.8L pistons (relieved for large valves)

3.8L iron ductile cylinder sleeves

Carrillo Rods

3 layer stainless core head gaskets

5 axis CNC ported heads

5 mm oversized valves intake/exhaust

315/305 degree variable high lift camshafts

12 mm head studs

SRM billet intake manifold

dual throttle bodies

SRM fuel rails

full PTFE full system

x-pipe intake with dual blow off valves

2 X 700 LPH brushless fuel pumps with controller

Syvecs ECU

SRM 4.5" intercoolers

2150 cc (205 lb) injectors

custom v-band headers with 38 mm waste-gates

2 X Xona 7865 v-band turbos

Switzer Exhaust with bypass valves

Tilton triple clutch

change from 20" to 18" wheels with MT ET streets

Helical LSD

DSS stage 5 axles

E98 fuel

 

The heads, cylinders and cams have been sent off for machining.

I agree with Erik - welcome to the forum!

 

This sounds like a pretty radical project for the winter.

 

Feel free to document the journey with us, online or by submitting a story and photos for our newsletter.

 

Good luck!

Welcome to the club vr6tee ...

 

I don't believe we have met, but you certainly have caught our attention with your second post to the website. It's an intriguing and courageous project.

 

As a life long DIY'er I will admit to never having undertaken an engine project as extensive as the one you have outlined above. Looking forward to your progress updates throughout the winter.

 

Would enjoy seeing a picture/s of your car in a subsequent post.

 

Again ... welcome

Thanks for the welcome guys! I uploaded pics of the Switzer build I did this spring, it was a pretty big transformation and gave me the opportunity to learn a lot about the 997. I came from building high HP VW's. I guess I still am :)

 

Here's a couple pics of the car:

I should have the head, cams, pistons, sleeves, rods, cylinders back within the month. I'll take some pics of the engine assembly as it progresses. The goal is to have the car running by March and ready to dyno when the snow melts.

HOLY. Yes, please share pics and progress. This will be a complete beast when completed.

 

Thanks for posting

Awesome project!

 

Did you buy an OEM Porsche cam timing tool or an aftermarket version?

It seems like one of the biggest things people worry about is getting the cam alignment / timing perfect, wondering if you've tried it before?

I'm "borrowing" an OEM cam tool. I bought a TDC indicator and have a degree wheel for setting TDC. I was looking at the Stomski GT3 cam timing tool which looks really nice but a buddy has the OEM cam tool so I might as well not waste the $1000 if I don't have to.

Cripes, that is some serious horsepower. What levels of boost are you expecting to run?

 

Marc

 

I have 5 different boost maps switch-able via my cruise stalk ranging from 17-35 psi.

 

My cams are scheduled to arrive back from Germany today.... I'm expecting all of my engine components/gaskets/bearings to arrive back by next weekend. After that, the engine assembly will resume.....

The long block is officially complete. Now I am waiting for receive my new clutch and turbo components. I'm hoping they arrive in the next 2 weeks so I can get them installed and then engine/trans back in the car.

Hats off man. That's a crazy undertaking and I love seeing your pics.

Also can't wait to hear and see your car in person.
