A 6 port is basically a 4 port right up until you open the APV so any mid-range advantage is minimal at best .

If your comparing stock to stock yes but a 4 port allows you to actually port the thing properly.

Their is not such things as "properly" porting on a RENESIS, you are still limited by your exhaust ports which nothing can be done about.

@ 28k might as well get a 3 rotor and have money left for wheels and a skank from back page Not to mention it's automatic -_-.

cool to see/know it was done.

Swap out the housings for 13b-gslse housings and make a custom 5 port manifold. Think outside the box, don't just say nothing can be done... At the same time you could also semi-pp that housing with zero porting. Boom lots a horsepower on a stock block while solving the side seal heat problem at the same time lol. Though you would have to resort to full height apex seals due to the extra heat.

Yes, but then it wouldn't be a RENESIS anymore :lol:

We all know how to do it, but the fact remains it was not done on this build.

Ok, then back to my original point. Look how much torque he made with the 4 port and where the powerband is. 5,500 RPM to 8,000 RPM with 350 foot/pounds of torque vs what the turbo 6 ports make. I bet you that late spool has more to do with the automatic transmission and the dyno settings also so it should be coming on even earlier. I bet that car would feel and respond a lot quicker then most of the turbo 6 port builds on here. More power under the curve means its more fun to drive and will win races. Also, less RPM means its more reliable due to less heat, especially side seals.

thewird

It made that much torque because they did two things the 6 port guys have not . Wound up the boost and used E85 .

There isn't enough difference in port timing on the (stock) 4 port to make any significant difference . They are practically the same engine up to 6300 rpm , after which the 6 port is superior . If that engine were a 6 port running the same boost and fuel the power curve would be much the same to 6500 , after which it would keep going straight up to around 500.




Plus anyone that has any sense limits the rpm on a turbo 6 port to about what that 4 port is running .......

Any updates on this build?

All Quiet..............
My guess is that they blew the A/T .

LMAO
lets hope not, maybe they ran out of money?

Car's driving and all happy from what I gather. Owner still has no issues so far.

Do you know the owner personally ?

We not allowed a rew swap in oz.. Emissions rules.

Not to mention scalloping of the rotors

Maybe u shld YouTube PAC performance cars mate, on the track.

Stealth!! Just what one needs to keep the cops off ya back around here.

any updates?

for 2003 models in some states yes you are..

Keep the thread on topic and watch the name calling gentlemen.

Thank you

No worries.
