comp is 10.44:1, ring gap is .022, and aparently my pistons only have a 1" crown, not very big, probably not good for the heat. The company that bult the motor just told me its not going to happen

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
i was thinking about e85, what all does that entail aside from a carb swap/rebuild? Then, only issue is wherer to buy e85 in central jersey :scratch:

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
carb swap pretty much,unles su can get an e85 compatable carb rebuild kit.
but yeah im central jersey to i dont think u can get e85 anywere in jersey yet.
im looking forward to when we can get it here though,cause the rs willd eff be getting a gas to e85 conversion

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
yeah that could severly limit how far u could drive,wouldnt be so bad if it was onl\y say 10 miles away,but even then u couldnt go far. would be nice if the racetracks started to carry e85 though. for ppl who run a standalone ems u could drive to t he track on pumpgas and swap and fill up with e85 and swap the tune in a few seconds

E85 at the track would be nice. I would like to drive my Camaro to the track on woodgas (free wood) and then run E85 for some 10 sec runs. That would be fun.
Eventually, I want to start playing with E85 and lean burn to see what kind of mileage I get.

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
Hey Rob,
Thanks for the PM.
I don't know if you have seen what my routing looks like:
http://members.cisdi.com/~anesthes/a...r/100_0992.JPG
But I'd like to run a singleplane with a 90* LS1 adapter. This would eliminate bunch of 90* bends and help with the cylinder issue. (some cyls run leaner than others as indicated by the plugs).
I think the Miniram is a great manifold for N/A or nitrous, but for boost i think a singleplane is the best. I went fastest, and had best throttle response with a singleplane and monoblade throttle body. Trying to get back to where I was in 2004. (otherwise I'm pushing the vette into the river)

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
Small Update....;
Just got ahold of my recent purchase, an '89 Iroc shifter w/linkage, so the B&M Megashifter is getting pulled in about an hour or so to make way for it. Also, I installed a set of AC Delco Rapid Fire spark plugs, and Flamethrower ignition module. I have a backup AC Delco ignition module ready just in case the Flamethrower burns out, don't worry....
Needs a major cleaning before install, but I like it much better though....

Going to have to pick up the pace with my turbo application, as my buddy Shawn just picked up his '88 GTA w/LS1 conversion today, and he's looking to turbo charge it as soon as possible. Can't have him doing that before me lol....

Update....;
Okay guys, this project has taken on a very surprising twist. I'm scrapping the fuel injection idea. I'm keeping the carburetor, and will be converting it into a blow-thru design (w/hat, no enclosed box) hopefully by the end of this week. Sticking with a mechanical fuel pump (a Carter strip pump), as my cousin just showed me how to convert it to reference boost. Won't be able to run as much boost as I'd like to, but hey, I'm more concerned with ET, and not just Dyno numbers. Chris, I'm thinking about the other set you have now, this way Dave would only need to fabricate the down pipe to the cat (w/cut out), as opposed to the crossover as well. Stay tuned....

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
Now, what I would like to do, is, have a much stronger set built in comparison to these from SSAutochrome. I'm kind of leaning away from the under the engine method, I'd rather have them meet up in the front similar to Dave's 3.1 turbo setup. Of course, not as high as Dave's coming from the passenger side, it's gotta remain under the upper radiator hose.... 



Wow, that picture looks familiar. I actually sold that intake infavor of an old school TPI...

There not and I don't care what SSautojunk properties say... The headers were made by Chris @ ForcedPSI.com, we were test fitting them on my C3 corvette trying to figure out a design for my build. Those headers were made for his 69 Camaro, which was in the first Hot Rod "Pump Gas Drags"You can check out more pics here if you like... Probably the place SSautojunk got them...

Re: Yet Another Turbo Charged Iroc, & Question For BBS Designs..... ;)
Rob, naaa, the BS flag was directed to SSautojunk… It just pissed me off when I saw the properties you mentioned and the fact those headers which are a work of art were compared to chinese junk. Your project looks cool and on track. Looking forward to your future posts. Good Luck!
