You'll see the most gains with a 3in from the turbo back and mild gains from a 3in setup from the cat back. The stock msp downpipe necks down to almost 1 3/4in so any bigger exhaust makes a huge difference. Though you can still feel a difference turbo swapping an NA car to the MSP turbo setup...

MJJ8 and MJJ9 are the turbo specific ECUs. What makes you suspect the stock ECU is going bad? They typically have a pretty poor tune from the factory that runs the car very rich. It helps manually resetting the car by disconnecting power to the ECU but you'll eventually run into the same...

Decide what your power goals are and eventual use for the car is. Once you start chasing power with these cars it becomes very expensive very quickly. I tell you from experience if you're expecting anything past 300hp it's extremely cost prohibitive and time consuming. Once you build the engine...

Hey there, not sure if you're still having issues but: For the exhaust system get the car up on jacks (safely with jackstands) and grab some pictures of under the car where the exhaust is broken. Usually you can weld a broken exhaust but if it's too rusted you may need to look into other...

It's been long discontinued. There's been recent demand for this unit in the last few years but no luck so far with getting another production run going. That being said your only way to get a setup is through the second hand market. If you still can't find one shoot me a PM, I may have a lead...

I'll take these, messaged you

Agreed on mounts, I'm giving solid Awr mounts another go however as Awr just started offering a refurbishing service where you pay a bit for them to repowder cost your mount and change bushings to one of your choice. They now offer a softer 62 durometer and after sending a trashed passenger side...

You really only have a few new options, all in my opinion are way too stiff compared to factory. BC coilovers and Yellowspeed. I think you may still be able to get ksports made but these are the two main ones left for the platform.

Go with the gtx2860r gen 2! Also the pope manifold although good, can be a pain in the ass to install..

Brian you mad man.. might have to turbo swap an auto p5 I may be getting in the future hehe. Would love to see how the car behaves with the turbo and how the trans holds up. Curious to see how smoothly the car shifts when stepping on it lol

Question, do you know if there are any distinguishing features that you can find to tell apart the early gen steedspeed t2 manifolds from the corrected ones? Also recently purchased and installed a steedspeed t3 from a guy who bought it new early in the group buy. Will have to check for any leaks.

Also if you haven’t already put the MSP shocks and springs on the p5! The ride so much better than the stock suspension. The fronts will sit a bit higher than the rear (like the MSP) and I’ve found aftermarket lowering springs for the front balance out the height and makes for a great stance...

Love the thread, great to see people taking on these swaps these days. We recently msp swapped a buddies p5 and it was good fun. I’ll tell you I’ve had the spectrum of bone stock MSP to full built block t3 p5 with haltech. Subjectively my favorite setups are the mostly stock MSP with supporting...

Please PM me, interested in the rear lip/ skirt plus a few other parts. Thank you!

Hey there, please PM me as I am interested in the front brake setup. Thanks!
