Guys. I have been following this thread. Great options for a replacement of the current turbo.

Could anybody please point me in the right directions on how to replace the stock turbo? I haven't been able to find these instructions and my turbo is leaking oil pretty badly at only 74K miles!!

Thanks in advance.

hmm BNR S3 Swap How To

This should help. Are you swapping with another stock turbo?

[Pololo_MS3]

I wish I had the funds to go with a better turbo but at this time, I will swap it with a low mileage 25K stock turbo. I know the turbo "sucks" but it will get me going... it's my daily driver. Really appreciate your help. Your build is plain awesome! !

update Head almost done being ported ( I think). Pablo's compressor broke yesterday though

Ok, got the motor in.

I ended up cracking my original head pulling my motor out ( yes I will openly tell about my fail). It wasn't my fault 100%, but I should have known better. So my old head will not be a usable core.

Good news is that I experienced zero fail putting my new motor back in. It started right up and all I had to do is prime the cooling system. Took like 2 days for this whole project from start to finish. I ended up changing a lot of pumps and gaskets; basically blew all my money on new stuff. I rebuilt my power steering pump and then my ac clutch. Both of these parts failed a few days after my swap, and I don't know why.

I am still on my break in tune and it hits about 17psi. Motor has 1,200 miles on it too. Hopefully I can get my car tuned before July 25th so I can hit the track.

My compression is good too!

1-175
2-180
3-174
4-183

I am running Manley pistons and they were really weird watching them seat. Compression was all over the place for the first 50-300 miles.

Pictures attached.

Thanks! There's a few other built speed6's in Alaska as well.

Update: According to VD the car makes around +/-340 whp (my front mount is really holding me back). Anyways, had a few track days and my last pass (last friday) was a 12.4 @111.64 (best trap was 113). The time could have been a lot better, but I was running into traction issues and should've thought about why more (its my fault!). I need to work on my 1/8 mile times badly. I am off to college now and will winterize and store the car tomorrow before I leave.

I have run into a compression issue but I am pretty sure its the injector seals. So the story is that I checked over compression a while ago and everything was about 180 across the board, expect for cylinder 1, it was 160psi. So I proceeded with a leak down test and found out my injector seal was leaking by spraying soapy water around the area and it bubbled. I reused my cpe safeseals and thought it would work for the time being. I parked the car in my driveway and tried my hardest not to drive it until my new Safeseals came in. I installed the new seals and took her for a drive and did another compression test. Now it reads 155psi across all four cylinders. I don't have time to screw around with the car right now, but when I get back I will try what Will said which is put some RTV around the seals and head. That will probably work the best. This whole situation is weird, and Will said I shouldn't worry about it because all the numbers are the same.

I also sent my injectors off to get cleaned for peace of mind purposes.

I also have a cold start misfire problem and I am getting close to finding out where that is coming from. But I am about to leave, so not enough time to do more diagnosis (either a coil or a wire in the loom).

I also sent my compression gauge to Pablo for testing. Shout to Pablo for helping me through this all !

Any update?

Update: Upgraded to a 5858 (Journal Bearing) with the CPE Precision V-band manifold, and Kosmic DP and dumptube. Also slapped on a TR1045 and probably other stuff I am forgetting. Im still running the stock intake manifold which limits me really to 1 methanol nozzle, according to my tuner. Running pump gas and a d014 methanol nozzle (biggest Devils own makes) I ran out of injector at about 28psi making near 440whp 380wtq PD tuned. I am still running pump gas only (90 oct) which people actual have done test and rate it still at about 87 oct. and straight denatured alcohol.


Pretty impressive numbers still haha!


I have a JMF IM and HTP 4.0" intake sitting in my room ready for install.

I also need to pull my engine out just to reseal my transmission. I will also delete my AC because I am having problems with the AC clutch AGAIN! While doing all that work, I will install my JMF and HTP 4.0" and try to get a retune started before I head off to college again. I plan on running dual d010's, dual d012's or dual d014's
