| I am assuming FSR is building your mani, right? Very exciting. FSR, AFAIK, has done extensive testing on their tubular mani. Sit down with them and make SURE they have given EGT's a LOT of thought as far as runner length and design. You MUST make certain that you are not going to have a rogue cylinder that is running super hot with elevated EGT from a MAX effort build..capiche? Running E-85 will help. It IS a custom one off mani so there is that issue!
Rears: 17 inch x 11 or 11.5 inches. Will need MAJOR cut, trim and fender flaring. 315mm tires should fit. Your body guy has to be super aggressive, however.
a modified Quick Spool Valve (so it will physically fit the engine bay) would be awesome for driveability. Look in to that. Need a twin scroll turbo housing. you dont HAVE to get a QSV, but it is highly recommended ...especially if you go over 71mm for a turbo size!
OS Gikken Super Lock LSD. A must have. I LIKE your diff brace. Mandatory. "Nuff said.
Axles...covered. DSS FTW.
Clutch, what ever. You will figure that out. Clutch Masters? Talk to HPF. They have something figured out already.
2150 cc FIC injectors. Forget about a perfect idle on straight pump gas...aint gonna happen
Intake PIPE! Critical. must be super non restrictive. Use giant hollow AFE filter. You may have to lose your AC compressor. It CAN be done and retain the AC. Very tricky. If you have great exhaust mani, you must have great intake pipe and filter, right???
HUGE -10 AN fuel lines, -6AN or even -8AN return lines...Kevlar braided Teflon core. All -AN fittings. Do it right. Monster fuel pumps. Need over 1000 lbs per hour fuel flow if using E-85.
I recommend the PRO SERIES EFI FUEL PRESSURE REGULATOR made by Areomotive. 300 bux at Jeggs. Anything smaller and the flow is not correct for using E-85 making 1000RWHP. Anything over 600lbs an hour you need to upgrade to the PRO SERIES FPR. Dont let anyone talk you into anything less.
Its an awesome FPR. Big chunk of billet!!! http://www.jegs.com/i/Aeromotive/027/13110/10002/-1
Fancy silver faced pressure gauge,,,,not too expensive. JEGGS again. Buy 60 psi max....18 bux! Steal!
Use Jeggs for AN fittings. Use Pegasus for Kevelar braided , teflon cored fuel line'
You can use SOLID SS tubing for under car fuel line too!!! More durable than anything else. You need Pegasus PROPRIETARY -AN fittings for any teflon cored fuel line. Every manufacturer is the same regarding this. Feel free to buy JEGGS -AN fittings for anything else other than something that is not permanently attached to any hose.
BTW, Jeggs has a LIBERAL return policy...up to an entire YEAR, yon can return stuff. I tested that out. They really honor that shiite. No kidding!!!
I would use the smallest turbo I could and run a crap load of boost if you have REALLY good intake and exhaust flow and E-85. In theory, you should be able to get 1000 rwhp with just a PT 7175. Supras with 2JZ motors achieve this. But everything has got to be JUST right for that to happen.
No one has gotten this sort of efficiency yet from an S54 motor....YET!!! I am positive that this efficiency level is possible VERY soon!!!
You have to have a LOT of confidence in intake and exhaust flows.
Larry has NO problem of running up to 40 psi (if needed) when using E85. That is a ballsy move and only recommended for the extremely brave. But, it has been done.
Somebody is going to get 1000 rwhp out of a PT 7175. But to be on the safe side, a 76mm is probably a better idea, unless you want to roll the dice.
I got more but this post is plenty long enough.
Oh, some kind of fuel accumulator so your fuel pump does not suck air. I forget the term. Somebody will bring that up. VERY important, critical one might say. I have a fuel cell so I forget the NAME of what you need.
Sorry for the long post. You asked. I brought up key areas.
