My name is Paul and i am almost done with my 1966 skylark gs with a 401 with a t67 turbo. It is a rear mounted setup with a blow thru carb. i am running full length headers, custom exhaust, custom inlet pipes, complete oiling return system for the turbo and hopefully some serious power. my question is thier a aftermarket high output mech fuel pump that will work with the nailhead? needs to support 600 hp. I really dont want to run a electric pump due to this is a driver and will be driven everywhere. i like the reliability from a mech pump. this is pretty much the last thing i have to do before i can get her ready to fire up and tune. any help would be greatly appreciated. Thanks Paul 1966 skylark gs (hope to do the next power tour, anyone near mass going?) c5 corvette brake,kor3 hubs, b body spindles, qa1 coilovers, hotckis rear springs,1 1-4 swaybars, 1 inch rear swaybar,billet specialties 18x7 (front) 20x8 285-45-20(rear) wheels, custom narrowed 9". detroit locker 3:73,tubular control arms front and rear, aluminum rad with custom lower rad support, and my favorite part a nailhead with a huge t67 turbo, 7psi!!
DUUUUDE....pix, pix, pix....c'mon you expect us to just believe ya? Well we do, but need pics to be sure....mj:laugh:
not a problem, i am a shop teacher and i will try to take some pictures of the car tomorrow after i get out of work. i have been working on this car for 5 years and have owned it for 10years. Thank to this board i have found alot of greats parts and unlimited infomation. So thanks for all the helo and any info on the fuel pump would be great!! Paul 66gs mass
i never saw a mech that would do that. they make some very reliable electrics though this interecooled?
not intercooled, it doesnt need to be because of the length of the pipes from the back to the front. They say you only loose about .5 psi drop from having it in the rear. But the charged air is about a 100 degrees cooler due to the length of pipe. i talked with sts for days but they wanted to much for thier kit $2600!! That was just a turbo, 44mm blow off valve and a oil pump. nothing else. That isent the $500-700 carb, fuel pump, incooler pipes, fuel lines, pc carb hat $300.i was debating wheather to run a intercooler or not. If this motor likes the boost and when more money is thier to play with i will methinol inject it. But as everone know these nailheads arent cheap. i firgure it is between$2,200 and $2600 to turbo a nailhead completely. i was talking to another instructor at my school and every year we build hot rods and rat rods in the school. we were talking about making a single turbo manifold for the nailhead and put it into my 1950 international pickup. That would bring the cost way down because of the oiling system. One day i am sure we will get one manifold done. but i cant wait til this one is done. if anyone is thinking about this swap i can send them all the turbo specs and oil pump specs and prices.

Try this guy for the fuel pump.. He doesn't have one listed (he makes a boost referenced pump for a 455), but I have talked to him about doing a high-HP pump for the nail and he said all he really needs is a stock pump as a pattern (which I have been meaning to bring to him since I'm only 30 miles away): http://www.robbmcperformance.com/products.html As far as your setup, I was/am going to be doing the same thing on my '64 riv. I too saw the flaws in STS's pricing and am in the process of scrounging up 2 GN turbos, but a single turbo would simplify it quite a bit... If you would please send me all of the details on your setup, from engine to turbo, it would be MUCH appreciated.. IN FACT, if you did a build thread with pictures, all of the nailheaders' would LOVE you.:beer I was looking into an oil pump from these guys: http://www.rbracing-rsr.com/oilsystems.htm I was also looking into getting two smaller intercoolers(for a TT setup) from these guys and laying them under the floorboards, due to lack of space in the front end of a 64 riv with AC. http://search.stores.ebay.com/CXRacing_cxracing_W0QQsaselZ301278660QQsofpZ0 Wes bilgerat671@juno.com :3gears:
My experience with a twin turboed Chrysler was that power was very limited due to detination, without the intercooler and MSD computers to control spark advance and retard and fuel air ratio. In 1994 the bill from Ak Miller was $5500 to do the above mentioned items. I would suggest the computer control and fuel air at a minimum and if you want to make useable boost, say over 10 psi, you will need the intercooler to keep things undercontrol. Mike
If you have access to a full shop, why not obtain a Pontiwhack or Cadiddliac billet hp pump, a new naihead pump, and tastefully Frankenstein it to work? Otherwise, supplement your mechanical pump with an electric at boost.:TU: Robert
We can build a boost referenced pump for your Nailhead. Cost is $200 for our 550HP version. It is special order however so it takes us a week or two to ship. Contact me at robb@robbmcperformance.com if you are interested.
i will be def getting in touch with you for the fuel pump. can i send a payment to you through paypal? with the turbo setup i am running, it is a garret t67 to4e housing, ptrim, .81 a/r and should be at full boost at 2800-3000 rpm's. i am using a fairly stock .30 over 401 that has been completely rebuilt. If i decided to go with a 455 one day i can keep the t67 and go to a .96 ar, they say the turbo is gd for 750 hp. i would love to see 550hp. i have been going back and forth with sts and they couldnt give me a good price so i decided after i mapped out the turbo to do the kit myself. Give me a week or two and i will try to get a step by step exsplanation of the pictures and how to and how much.. the most exspensive thing was the turbo $900 new, carb $500-700(undecided)Wastegate $300,tubing $116/ oil pump $340,oil lines and plumbing $100, The look on someone face when they see a turbo nailhead priceless!!
hey rob, Today is friday and i got paid!!! :beer .. i want to order that fuel pump with the boost reference. feel free to call me at 7742632277 or i will try to give you a ring at the shop asap.. been busy and really havent had much time to work on the car. tring to finish up on the body so i can get the rear quarters in primer for next week. i want to take the car for a :3gears: and see how it goes. ones question for all, what year dodge truck does the rubber gromet for the valve covers fit the nailhead finned valve covers? i saw a note about running efi on the nailhead. i have been looking deeply into running megasquirt. i have a spare qjet intake and i thought about drilling for injector bosses. do i have to weld them or can i two part epoxy? hope everyone has a great weekend and i uploaded i picture of the car from last year right before i took it all apart again to finish up on the body. i will be taking some more pics shortly when i can get a nice day out. Paul from mass
if you are going to try to avoid welding in the injector bungs, may I suggest threading them in conjunction with using the epoxy.. especially since your application will be "under pressure".. Also, if you are going to use a stock intake, I would suggest using a regular "square bore" intake for the EFI conversion.. they are much easier to find, not as rare or desirable as the q-jet intake, and most EFI throttle bodys are square-bore bolt pattern anyway... shoot, I'd be willing to trade you a spare square bore maniforld for your q-jet mani. I'll even pay shipping:TU: wes
Well, this wont be popular, but why efi? Alot of hoohaaa on the subject, everyones got opinions, but i researched this for 3 YEARS, read everything i can find in print and on the web, and i came away with a whole different view on this subject, theres a guy on ebay that sells a book,(its a mess, just different short stories pieced together) its a start. will find a listing and post it. Theres tons of info on blow through, hell theres website for it, the turbo mustang crowd has made it work with phenominal results, and they proved thayt efi is a "waste" of $$$$,not that it doesnt work, because it does, but because the carb stufff works, and works so well, guys are converting from efi to blow through carbs.....Carburetor + Boost Tech Questions, before you spend any money, take the time to read through this stuff, you'll be impressed, i have a pretty new carb hat for sale. DO one thing, read the recomendations for the carbs, and the hat etc, so much real world r&d its invaluable, and they make it work......
well there are so many other advantages of efi besides just for use with a turbo no way you have as much control or tuning capabilities with a carb that you do mpfi system. not to mention cold start up issues. driveability issues etc... also there are more than one type of efi
Both of you guys are completly right!! the efi thier are so many advantages to it, you can with the double click of the mouse on your laptop you can change your injector pulse, pull timing out with ever pound of boost and have it set up like a obd11 at 260 seconds it starts to check your monitors and go into closed loop. i really do enjoy the efi setup, but i am going with the blow thru carb. not that i can not do a efi, but for the fact it just makes it easier. i will be running o2 sensors in both banks and i will be pulling timing out with a msd box, i will be using a boost reference fuel pump(thanks rob) and a carb that is tuned for my setup. i want to run the carb just because. i have 46lbs fast injectors. i have the injector rails already and most likely i would use megasquirt setup. Cant beat the price and availibilty of gm parts you use for it. i guess at the age of 25 i am just old school guy and i just like carbs. o No: i guess it is all preference and what ever you enjoy more you should build!! hell who doesnt love a 4150 series carb!!!
i like both myself but efi nailheads arent common so it would be a double tap of awesomeness turboed and efi
