Fp Dsm82 setup questions

[CDgr97GSX]

Hi guys. I just got my turbo from FP together with FP manifold, 2.5 O2 housing and a Tial Mv-r...and after a quick look i sow two holes in the turbine housing. I was wandering what are those holes for and if i should leave them open or put a small screw in. Because i have a Aem Tru-boost controller and i just order an ETS intercooler i was wandering where should i connect the boost solenoid without drilling the turbo compressor side...does the ETS came with something for a boost controller or do i have to drill the pipe myself? Thanks

The threaded bungs in your turbine housing should be for either mounting a heat shield, or you could add an EGT probe to the one below the manifold flange (since the collector is the optimum place for take EGT readings from).

As far as a boost source goes, I would recommend drilling / tapping / jb welding a nipple into the pipe that connects to your compressor housing.

Thanks for your answer. One more thing...what injectors should i run with this setup. I have EcmLink and i want to be able to dial them easy and have a good idle. I might use race fuel so high impedance injectors is not an option. Thanks!

Go high as you can since you have link.

The high Z injectors would be a great option if you have the money

That's the problem. I've been reading a lot about this...trying to decide what i should get. With the high impedance i'll have nice idle and they are easy to tune...but i can use only pump gas and E85...and since E85 is hard to get here i'll run the car only on pump gas...so i can't maximize the turbo. The only way to make some decent power from this setup is to run race gas...and then i have to run low impedance...but i've read that bigger then 1300-1400 they are hard to tune with bad idle run. I was thinking at Fic bluemax 1250...is a good compromise?

I would say you NEED at least 1600s to maximize a 75 lb/min turbocharger.

Probably you are right...but i can't stop thinking about how they will work at idle or low rpm with some cams like FP4 or 272.

You could just bump up to a higher then stock idle like say 1200-1500?

Then get the high Z injectors. The don't have the dead time lag in the low end like the low Z injectors.
