Ok so here's the deal. I love the pro touring drag truck look. I know this isn't the truck section but they don't have a boost forum. So, that being said, I'd like some advice before I start chowing down on pigzilla here. It's an 82' D250 single cab long bed. One of my neighbors does fabrication work and has offered to do the major stuff for me like back halfing and boxing the frame, swap to short bed, custom arms and coil-overs, lowered, ect. I'll have a strange S60 with a triangulated setup. 727 with a gear vendors overdrive. A Mopar Performance 440 block and plan to stroke and bore it out to around 540ish and go fuel injected. What I really know nothing about is fuel injection and turbos. I'm going to have a converter and cam made for my setup, not sure on rear gear yet, but being able to drive it on the street is my goal. So any advice on turbo size, boost, harness, inter-cooling, ANYTHING, would be greatly appreciated. :prayer:

Sorry for the novel. :book: I'll post some pics of the truck as it is now after the weekend.
 
No it's going to be an aftermarket block designed for large bores with thicker webbing. I'm still considering the same thing but in a hemi. I'm not sure yet.
 
I"ve been looking it to aftermarket efi and boost for the past couple of weaks and it seems the best rout would be to use the FAST sportsman xfi, there distributor and peace together the rest for a sequential port injection that can handle up to 5 bar = 58 lbs of boost. the other option for a kit seems to be the edelbrock system but it can only handle low boost levels and moderate hp. theres also megasquirt but i realy dont understand that system at all.
 
For the fuel injection I thought about giving FAST a call.
I haven't looked into Holley yet.
 
I just installed the Fast xfi 2.0 and have been very happy with the performance. After setting up some target maps, it has been self tuning and running great. I'll be dyno tuning soon to get the top end dialed in, I am running pretty conservative so far.
 
Why stroke a turbo motor? You may be better off spending the stroker money on your EFI.

One thing I have learned form chatting with some very knowledgeable folks over there is not to buy into the low compression bs. Don't remember his name, but if you spend some time on YouTube looking for "Matt's Dart" you may find one very wild Dart. Has an aluminum blocked wedge with a big single. Pump gas, no inter-cooler......meth injection is being used as a charge cooler. Started out with a low compression build, believe it was 7.5:1 or so. Had a failure and rebuilt the block. Pushed the compression up to the 10:1 area....motor obviously ran better off boost....and made more power per pound of boost....on pump gas...than with the lower compression ratio...

The Fast 2.0 does tune with boost. You build a target AFR map based on your map sensor. Mine for instance is a 2 bar. I just ball parked my AFR's for E85 and deliberately set them to be rich. Every time I drive the car it is more crisp. The car runs better now than it did with my dyno tuned haltech.

I think dyno tuning by an expert is still a must, because the Fast doesn't work with timing. I again went conservative with the timing map. I will hopefully get into a dyno shop next month and will report back with info and video :).

doesn't work with timing? as in there is no boost retard, or you have yours set up as batch injection, or something else?

very cool that it self tunes with boost though.

Sorry, I didn't say that very well...It doesn't self tune timing. Timing maps are all user programmed. You can do batch or sequential.
 
Pishta: Why not? ha

MrMoparMan: What kind of setup are you running with your 2.0?

When I talked to FAST they said the system wouldn't run with boost. Are they just saying that so people don't stick it on there thinking it's good to go and tear up their stuff?
 
here it definitely advertises boost capabilities [ame]http://static.summitracing.com/global/images/instructions/xfi_ecu_operationmanual.pdf[/ame]

the rep my have been talking about the EZ efi which isnt boost capable
