They are bigger and less problamatic but still need porting after some basic modding.

 

Yes, thats about right.

I have an S4 with the RB 3" turbo back, OEM K&N, rtek 1.5 chip, walbro pump. I dynoed 210 rwhp. Add about 15% gives 245 or so @ the flywheel. Oh, boost is about 7-8 and creep to 9-10. (Need to port wastgate alittle bigger this time.)

 

Yeah i will definitely make sure this thing is tuned right.....i dont want to have any problems. Man I am kinda scared now....i dont want to see my pride and joy go Kaboom!!!!!!!!!!!!!

 

is there any other way to stop boost creep besides porting the wastegate?

 

Good Question....any answers guys?

 

"i dont want to see my pride and joy go Kaboom!!!!!!!!!!!!!"

Yeah well you are leaving yourself open for alot of fail points.
1. You are using a NA rear end and half shafts. If you see the difference in size between a NA half shaft and a t2 half shaft you won't want to run the NA's at all. And just to let you know most of us have broken T2 half shafts before so don't expect to run 13's very long without the rear end letting go.

2. You are using a J-spec (J meaning Junkyard) motor that has sitting on the ground in a bone yard for who knows how many years. Also you are not getting a rebuild so you don't know exactly what shape the apex, oil, and coolant seals are in. Now is a good time to rebuild and port because you have a good core motor. If you blow it up only half the motor is good and your rebuild just got alot more expensive.

3. You are not using a standalone ems system you are using a "piggy back" safc. This will add to the wiring nightmare the 88 harness to 89 motor will already present. Not to mention you will need to get the primary 550cc injectors cleaned or your asking for trouble.

If you want more info on t2 swaps you should really talk Kevin Landers at Rotary Resurrection. For the money you are spending you are better off buying a t2 and selling your NA for a EMS system for the t2. The only NA worth swapping to t2 is a vert. But I have a feeling you won't take my advise and buy a t2 and you will be back here posting
"where to get a rebuild for cheap?"

 

Yes - the S5 waste gate is better, but when you open up the exhaust & intake, you can overload it.
I simply "unclogged" my cats & my boost pushed up to 14PSI in 3rd.
My DIY port job brought it back under control at 5-6-6-6-6.
Then the MBC can be dialed up according to your fuel system.

 

Well guys I found a complete T2 Rear Subframe so I am fully running the T2 Drivetrain. Everything is beginning to shape up and we are shooting for 260-265hp at the flywheel. There is an S4 T2 up there w/ similar mods and it makes 250hp at the flywheel with the S-AFC tuned. And yes the wastegate has been fully ported. I am gettin really anxious...in less than a week I will be feeling NICE amounts of boost.

 

You realize the 59hp claim from Racing Beat is on an S4 motor/ecu combo. That stock setup makes 180hp so adding 59 makes 239 at the flywheel. You can't add 59hp to an S5 TII's numbers, the improvement from the exhaust isn't as great as it is on an S4.

 

Your right, but I believe coming from a 183rwhp N/A setup to this 240hp+ Turbo II Engine I will notice a BIG difference. I see mid 13's and with good tuning and some slicks low 13' easily attainable with good 60' times. But yeah hopefully at 11-12 psi I cn get 240-260hp at the flywheel. Someone told me with all these mods I would make 200-220 at the flywheel and the BONE STOCK Engine makes 200hp at the flywheel so I find that VERY INACCURATE.
