Hello all. I have a month before I start to take my engine apart and start porting. I have been doing a bit of research but have not come across much 6 port turbo ports for .... obvious reasons. (there arnt many people people turboing NA engines)



Anyways I was wondering if there were any tips or rules I should be looking for as far as a street port for a 6 port. Is it pretty much the same as a turbo 4 port or is there more to it? Here are a few of my ideas I have been tossing around as I day dream at work. I'm sure some of these are bad ideas but other then just saying "no it wont work" could you explain why? That is the only way I will really be able to figure out what I am looking for. I am looking for an OK idle ok gas milage (15 mpg is fine I get 23 mpg on my turbo na right now(highway)) and I don't want to have only power after 6000 rpm. I will be getting the engine balanced but I don't think I have enough money to be able to make the engine able to handle 9000 redlines while drifting. Here are the ideas I have been throwing around in my head. Most have to do with getting rid of the center section between the ports.



Stock ports

Showing the areas possible for porting I think:

Showing what leaving the middle thing but porting close to it

https://i172.photobucket.com/albums/...es/report3.jpg



Big port ( I think it could get a little bigger if I went more to the outside red)

Just the middle section gone

so with all of this are you still going to keep the 5th'6th port inserts or are you going to ditch them and try to run it as a large 4 port ?

TweakGames 09-30-2007 04:03 AM

I have already ditched them because I am running a turbo setup. Would this just be a large street port or would there be other issues like only power after 10,000 rpm?

j9fd3s 09-30-2007 03:15 PM

imo i would the only real change id make, is to not close the ports later, open em early, make em bigger, but the 6 ports already close late, and with a turbo you dont really need later closing. later closings going to move the peak power up, and this is good na, but not really needed in a turbizzle

This is sort of what I am doing. Using 6 Port END Plates



T2 Center Section and Rotors and Housing.



Talked to Rob over @ Pineapple Racing this last week (He pressed my bearings in for me). And he thinks I am crazy.



I am using Pineapple Racing Templates as well.



The 6 port is much like a bridge ported motor. A huge amount of additional intake timing for the cost of swaping in some plates.

My Project Zuki



I am hoping to make this done in 30 days...

that website is crazy. And you sir are also crazy. Congrats on everything you have done so far. Amazing.



Anyways, I have a few questions specifically wondering why you chose certian parts. Why did you choose the t2 center housing? I understand the t2 rotors for lower compression, but any reason you chose the t2 housings?



Do you have any more pictures on how much the template takes off of the stock port? I would like to see exactly what it is doing, either opening earlier, staying open later, or just making the port bigger?



Do you think the haltech is required? Do you really like that EMS? opinions on it?



Any dyno results on any of the past builds you have done with the engine before it was turboed? Or do you have it running turboed now?



THANKS and you are awesome! https://www.nopistons.com/forums/pub...#>/biggrin.gif

may I ask also, why the 3rd gen flywheel?

The T2 center plate has a LARGER port then the N/A Motor. So I choose to use it and also port it via Pineapples template. The N/A Port has a TINY port on it.

Stock Turbo Center Port



I'll have to look at home, But I did the mid-level port from Pineapple. Not yet finished with my exhaust ports. Also running a 3" downpipe so this thing really flows. It's lighter than a RX7 and has a 5.125:1 rear gear ratio.



Using the Haltech because it's a motor swap... Would have taken much more work to transfer over the wiring. The Haltech is outstanding. I use it for NOS control and my shift light. It's costly, but allowed me to run 16 PSI of boost on this motor.



I had a very tired motor. It was very fast, but According to my Gtech was only putting out 220 HP. When I blew my apex seal I had no compression on the front and rear rotor. It should have continued to run on the front rotor, so I don't think it was putting out the amount of power it should have.



I know it looks a little crazy, but it's streetable and super fun to drive. People look... and Stare, but that's part of the fun.



1st to 2nd shifts were insane under WOT.



I'm pretty sure with some slicks the thing would lift the front end.

Because it's lighter than the Turbo2 and made of steel.



I got a heck of a deal on it too... It's been surfaced and looks brand new.



20 lbs. Vs. 23 or 27 for the Turbo II

I've always wanted to build a six port turbo but one ported like this one http://www.yawpower.com/dec2004.html maybe one day when I'm bored.

micaheli 10-05-2007 01:41 PM

Wouldn't a 3rd gen flywheel require a 3rd gen front weight and 3rd gen rotors as well?

s5 stuff works

TweakGames 10-05-2007 03:04 PM

Dac .... If you have to run s5 rotors those are going to be higher compression... Even if they are t2 s5 rotors.

They are S4 T2 Rotors.



I'll post some pics soon. I'm just about done with the exhaust porting and then will begin putting it together.

Going to paint the whole car Line Green... so the Motor and Trans will be Lime Green as well.

Thats a pretty bold paint job. Why didn't you go for the gold and paint it hot pink?

I know your being sarcastic. The color is more of a lime green. the hue is way off in the picture but hey it's it was taken with my iphone under florresant lights.



I'm tired of black... I have 3 black cars. Lime green is a little LOUD, but then again so is the car.

Very nice. That is the first time I have seen a whole engine painted! Normally you see the whole striped effect. Are you about ready to put it in?

Yeah I debated about that. My buddy says it's too much green. But I don't have everything on the motor. That is a mock up.



I think I'm about 30 days away, but now not sure about my flywheel and my found out my turbo is chewed. Apex seals when through it, but visually it looked okay until I pulled the housing apart to port the wastegate. I'm stuck using a S4 Turbo due to space restrictions in the Suzuki. But it was putting out 16 PSI of boost before I killed it.

TweakGames 10-11-2007 05:44 PM

EEEEKKKKK 16 psi on stock s4 turbo?! Please dont say TMIC. :( If so I'm pretty sure ..that's why it blew. The stock turbo is only good for 10ish psi with stock TMIC (read top mount interheater). I wonder what power you were putting out right before it blew though. https://www.nopistons.com/forums/pub...#>/biggrin.gif



30 days. I am counting down. I can't wait to hear/see some numbers!

I had 160K miles on the motor. So yeah it was time. When it spit a Apex Seal out through the Turbo it should have kept running on one rotor. So my guess is it was time.



The TMIC is my ONLY option. Remember this is a motor swap. I don't have huge amounts of clearance for a FMIC. I'm also running NOS.



Don't diss on the TMIC, Remember just a few years ago Turbo Charged cars didn't even have IC'ers.



The worst that would happen is Detonation. I only ran 2 passes at the drags....

Here is a video of a run I made when it blew. Zuki-r @ the Races



I wasn't running NOS (The tech inspection made me pull my bottle for a lack of a safety blow off vent.).

TweakGames 10-13-2007 08:15 PM

wow I can't wait for you to get it going again. Ever though about meth injection to get the intake temps down to a server temp?

pvillknight7 10-13-2007 10:13 PM

I was being sarcastic. I know sarcasm doesn't come across well in writing. I honestly think it looks cool. It is a bold color but its going to be fast so that makes it ok https://www.nopistons.com/forums/pub...IR#>/happy.gif

I'm curious the engine bay will look once everything is reinstalled...

When I drove it previously.... Stop lights where is a B*&th at least for the people behind me. The exhaust on this thing is really nasty. So I have thought about alternative fuels. But I probably wouldn't be able to afford to drive it then.

The car will be green, but it's not getting a FULL paint job, so the engine bay will remain BLACK.
