PISHTAS turbo build
So say I want to do this in stages. Start off with boost gauge and A\F, J-pipe, eBay turbo, 2 barrel carb and a boost referenced pump, and 5-6 pounds of boost. Can I run a stock ignition? Other odds an end parts?
Once I got that sorted out and was ready for the next step would it be reasonable to add water-meth injection, BOV, a timing retard system, modify the carb for boost, and move up to 10-12 pounds? Other odds and ends? Would it be easier to just start here or is working up a good idea?
you will need a holley 2300 or some other kind of boost friendly carb. do these mods to it, they are easy.
http://www.hangar18fabrication.com/blowthru.html i dont think the stock mopar 2bbls will play nice with boost. you will also need a wastegate if the turbo you get doenst have an internal setup. bov is a must, unless you just want to keep buying turbos. stock ignition will work but you will have to lock the mechanical advance in the distributor. its outlined in my build thread.
http://slantsix.org/forum/viewtopic.php?t=54407&postdays=0&postorder=asc&start=60 that should get you started for low boost. i can tell you in all honesty that once you feel the 5psi that you will want more almost immediately. it might be worth getting some things setup on your car that will function n/a and work your way up to the turbo. a boost ready carb will function normally without boost, the afr gauge will do the same. the fuel pump and regulator will also work n/a.
everything on this list is essential to a performance build. you could get away without the intercooler if you keep the boost low. i knew i was gonna be going all out so i got it out of the way from the get go.
hp valve springs $40 ebay
used holley 600-650 double pumper $50-$150 new $450. setup for blowthrough $550-$750
rebuild kit for carb $35-$45
hangar 18 mods are easy. if you can rebuild a carb you can do these mods. seems like a lot when you first read through it but its really easy when you break it down and start doing it.
nitrophyl floats $12 on ebay
spectre 9849 carb hat $65-$100 for high and low profile 98499
aem uego wideband o2 sensor and gauge $170-$230 plug and play, works well
ebay/china t3/t4 turbo kit w/ oil line, bov, wastegate, heat shield and exhaust flange $189. this turbo actually recently took a crap on me. spend some more for your turbo lol. hx35's can be had for around $200 used and will push up to 27psi efficiently. they are hearty and hold up well. you pay for a quality turbo with them not just the name. cxracing has a line of gt35's that are sized right for a slant. they are american engineered and china built. they stand behind their turbos and have a good customer base. their turbos seem to hold up pretty well. you could find a grand national turbo but i think 300hp is just about the limit if not stretching the breath of that particular turbo.
turbo $100-$5k
ebay 31x11x3.5 bar & plate front mount intercooler $98 this actually turned out to be a quality piece. really happy with it.
ebay 3" intercooler piping $109-$150 depending on couplings, bends and diameter
2.25 j pipe $35 jeggs all day.
3/8" exhaust flange that bolts up to the stock manifold $5-$10
t3 flange $10-$20 including gasket
2.5"-3" exhaust adapter $7 not necissary, i just wanted 3" exhaust. lol.
4bbl intake $100-$175
stock exhaust manifold hogged out, free
oil return pipe, scavenged from a dsm turbo i had kits are $30-$60
brake line for oil feed, vacuum, boost referencing $25 for 25' you are not going to use it all but its always nice to have some brake line.
boost/vacuum gauge $15-$40
regulator and electric pump are a must. if you have done your reading you will have come across an article on allpar that states the mechanical pump referenced will work up to 16psi. i found it inadequate for 8psi. going lean with a turbo is bad. real bad.
mallory 4309 and aeromotive 13301 are pretty common and work well. both priced around $100
walbro 255 inline pump with mounting kit $90
felpro 2104 steel reinforced carb to carb hat gasket $10-$20
throw in an extra $100 for various fittings AN,oil feed, just all kinds of random stuff that is overlooked.
if you dont run an internal wastegate you will need an external $60-$300. spend some money on this its what is going to keep your turbo from over spooling and blowing your engine.
bov $20-$300. gonna wanna spend some money on this too. cheap will get you by but you get what you pay for. im currently running a $35 piece and it surges.
