Lets Start Modding This Turbo Coupe!!!

November 11, 2011, 08:59:12 AM

I know i've posted this twice but Im hoping to order my DP today after hearing yalls thoughts.

Ok Im looking to get started on some mods on this car. Everyone does things their own way and my way is to get the motor to a power level I can live with till I finish the rest. :)

Ok so here is the order I want to do things but I want yalls thoughts on this and help if you will.

1. I want to upgrade this exhaust. Im thinking a single turbo back 3in exhaust but Im not sure on how to go about it. I would say I need to order a 3in downpipe and have my ler guy go from there.

I would think since back pressure is the devil of a turbo that a strait 3in pipe to the back of the car would be the best way to go. But I dont want probs not being able to hear myself think. With all that said Im thinking 3in DP then 3in pipe with no cat to a 3in ler and dumped beside the trunk.

Main thing I want is flow and the second thing I want is to clearly hear that turbo whisle. :D

2. Is a Front Mount Intercooler, Blow Off Valve, and an Elctronic Boost Controller. I want to take the boost to around 16-18psi. From what I understand my car being a 87 means it has a tiny turbo on it and 18psi is the highest "safe" psi I should run.

3. Is I want to get and install the 1.9 Bo-Port Cam Kit. I want this cam because it looks like a great cam and to e honest I want a loppy motor that just sounds means. What I need to know here is if I can run this cam without having a tuning system and running on the stock computer system.

4. I want to get me a Moates burner and whatever system I need to run it to start playing with the tunning of my car. I've always wanted to learn this stuff and I know I can use it to make more power when I do upgrades and such. What all do I need to start this?

5. Its time to upgrade the fuel system with a 255 pump and a FPR.

6. I want to upgrade the turbo to a T3/T4 unit and take the boost up. Not alot but I want the 300hp range. I dont know that these motors are capable of in stock form. I still have a ton to learn...

Im hoping to have all this stuff done in this order by Feb-Mar and then I'll start on the susp. :)

1) 3 inch all the way back. Personally, I would take it all the way back and exit under/past the bumper to keep exhaust noise out of the car.
2) Front mount, good idea. Blow off valve, not really. You need a bypass valve that dumps the air back in ahead of the turbo. VAM/MAF equipped cars will spike rich when a BOV is used.
3) Perfectly acceptable to use that kit with no tuning system. I would highly recommend a wideband and an ajustable fuel pressure regulator to allow you to monitor what's going on with the mixture, and make SMALL adjustments through fuel pressure until you upgrade to a tuning system of somesort.
4) Check the Moates site and see what they recommend.
5) Yes.
6) A T3/T4 hypbird of some sort will certainly get you to that power level and them some. However, that's pretty much the limit for the stock 35# injectors. You'll need larger injectors and a way to tune for power past that level. Also, soon after that, the stock Vane Air Meter will start to be a limitation. You'll need to decide on a solution for that, whether it be a MAF conversion, or just stepping up to a stand alone such as megasquirt or the Stinger PIMP setup.

I would recommend the Moates Quarterhorse for the emulation tuning and datalogging. When you get there.
