From ashes

How's the drivability, start-up, and idle of them? IMO, you're better off buying injectors for your current needs, then replacing them later on if it turns out you need them since you'd be retuning anyway.

Do you mean Wiseco 9.0:1 pistons?

[Halon]

Good to hear you have a plan to move forward.

Just out of curiosity, does anyone see any cracking on the Evo X Wiseco's like were sometimes seen on the DSM ones?

2000cc injectors and a full face organic clutch???

Those two don't really seem to go together but good luck on the build!

Room to grow if I want to later on. Can always tune them down.

Actually, it takes some work to tune the 2000s down even with E85. High imp Bosch 2000s/2150s/2200s/etc tune pretty decent with a full standalone. But even though those style of injectors respond well, factory ECUs do have some problems with them just because of size. Even with a standalone, they often still have to run rich at idle on a small displacement per cylinder motors, since their min pulsewidth often gives an AFR in the 11.0-13.0 range at typical idle airflow.

The new FIC 1600s would be perfect, but they won't be out until early next year sometime. The current 1600s, 1650s, 1680s all have undesirable problems.

Copy and paste from EvoMN, just saw this now, but I think its mainly agreeing with most people on here.

I wouldn't get the 2000cc injectors...even on E85, you will not love them. They are livable but a 1600cc injector or smaller will be the ticket. Since you won't drive yours in winter I would try to hold out until spring for the new FIC injectors, they will have 1400cc ones that will be more than enough for your setup. Hell, the ID1000cc's or if you want MAP1000ccc injectors should be enough. I ran my DW1000's to 500whp on e85 with a double pumper and AFPR.

I know it seems smart to not have to buy injectors ever again but frankly the smallest ones you can get away with is the smart thing to do for drivability.

Also, I agree, get cams now if you ever plan to...

FYI all the cool kids have 2000s

[Trogdor]

Murlow, when you say "liveable" what do you mean? I guess I'm not familiar with what having larger injectors would do if I'm not utilizing them to their fullest.

[Shane@DBPerformance]

Those injectors are just massive is the problem. You have to do special hacks to the factory ECU to try to get it to be able to even have a chance of running those injectors at idle and low airflow. It isn't just a matter of changing the injector scaling and deadtimes like you can do with even a big 1600cc injector.

[Murlo26]

^Yep, what Shane said.

You will just have an overly rich idle, you will have to run in open loop all the time so you won't have trim correction, you will probably bog at certain rpms/loads, possible die coming to a stoplight etc etc...oh and traffic won't be fun I am sure.

One thing I have learned is fueling is everything to a smooth ride. After months of farting around with every table in my tune the fueling is finally where its supposed to be at almost every spot in the rpm range, no unexpected changes following MAF vs MAP etc things and the car runs great. You will have issues with the 2000cc ones.

Even Tephra on his 2.5L evo x on E85 didn't get them to run perfect.
