Shoul I buy these parts for DR750 daily driver?

[SoarnBy]

I will be daily driving my car and never tracking it nor launching my car. 99% of the time pump gas 1% E85 My power goals are 450ish awhp on pump gas and 550ish on e85.

Should I buy these additional parts to my build? IPS Motorsports will be doing my build. Ray has given me the setup.

300m output shaft
2 piece carbon fiber drive shaft

Alan, please make this guy post up ONE thread for his build and not 100+ threads with every possible title imagineable.

Nope. Ray uses the stock OS and it works fine. You will need a billet endcase for your 6-speed though. I'd only upgrade the driveshaft if your carrier bearings are shot; otherwise, that money will go further elsewhere. You'll want to add an HKS DLI to the list, ditch the MAF since you can run speed density with AEM and IPS will prefer tuning it with this, upgrade the fuel rail loop to an aluminum one for peace of mind even though Ray saw different F&R fuel trims at 600AWHP on E85, get some upgraded motor mounts, downpipe, gutted precats, a wideband, and I'm sure some other things I'm forgetting.

Other than what Turbosincebirth said I would upgrade intercooler+piping and preferably a larger plenum and tb to let those dr750 flow as they should.

Nothing on your "Should I buy" list is needed. With your stated intended use you seem to have all the power needs covered, but for the inter-cooler.

What if he lists DR750s in the title? Would that technically make it a new thread each time?

1) Aluminum rail feeds are not longterm compatible with high ethanol percentage fuels. 2) 550whp isn't even close to the "you need this" billet end cover... When you get some results of your own you'll know better.
