basically i spoke to street lethal he asked if i had a build thread so now i think its a decent idea. anyhow my 86 has a perfectly rebuilt 305 itd be a shame to take it out i put vortecs on it with jegs intake and a 750 carb metered way down. currently the car has a t5 but i get alot of crap for this im just not a manual guy so my neighbor gave me a BOP 400 full race built which may be much but id like to use it. anow i put this in power adders mostly because im thinking of going a cheap turbo route somehow. Ill admit ive been trying to pick up on whats going on but know nothing about turbos, or blow through setups and all that so im wondering if this could be sort of a discussion, maybe future build thread.

as for the rest of the car ill be going torquarmless with a ford 8.8, not sure what gears, what stall what cam or what turbo. i know all those coincide with one another. also itll have the basic sfc's, lowering springs, battery relocation and minitub.

so what does everyone think? im not ready to go bigger, im not ready to go lsx im gonna stick with what i have, keep costs down but not skimp out yanno, not trying to be one of those guys or anything. so what cam, gears, stall, turbo etc would everyone recommend, what kind of turbo setup etc etc. let me hear what everyone thinks, good and bad.

what i need so i can keep track
Ford 8.8(gears?)
SFC's
LCAs
400 trans adapter
400 trans mount
shifter
turbo, tubing other related items
Driveshaft i(can make at work)
Stall

Build thread is important because it will allow for many different perspectives, as well as push you to get things going. IMO, sticking with the 305 is a good idea. You can always jump to something bigger later on, but once you get a taste of boost you will realize that you don't have to, as the 305 will be more than sufficient. First things first you need to plan out your turbo setup. Depending on the size of the turbo you want to go with, this will dictate which cam, stall and gears you will want/need to go with. Cylinder heads aren't as important as people make them out to be, just a good cleanup on those Vortecs will suffice, believe me. I only say this because I have seen stock LC2 heads run extremely fast, and they are garbage. Get some pics up of the vehicle so that everyone can get a good visual of what your working with, and so that this project can get started because spring is right around the corner...

the vortecs had a decent polish job on them, redone valves and seals and all that as well. how shall i pick turbo size and how shall i pan out a turbo setup?

the 305 ran strong, both my 305s were very strong motors and i think with the vortecs the compression would have dropped a bit so if im right in assuming that would help with some turbo action as well.

Many opt to go twin, but I always recommend staying single turbo. Joe went with the XS-Power single turbo system, and it is really a decent setup. Just needs some mods to make it right, but for the money it is a good starting point. First question of course is how much power are you looking for, and how high do you want to spin the engine to get you there? Knowing this, we can essentially tailor the right size turbo at just the right amount of boost pressure to get you there...

id like to stay single for now like suggested. the 305 is a complete stock bottom end as far as i know. id like to kjeep it in tact and not push it way close to its limit but i know ill have to spin it a tad more than usual. also with the 400 i have a bit more ability to target certain rpms although if i usd my old 700 i could too as it has a manual valve body as well. so if i remember correctly i can probably hold around 4500-5k maybe? i like to keep it somewhere safe though. not looking for loads of power, maybe 350-400ish. maybe that estimate is low ive never really experience a 305 with a turbo so i dont quite know what an apropriate goal is and i feel dumb not knowing but i guess thats why im here.

also the more i think about and not to get to far ahead of myself but i feel like my mechanical fuel pump may not be enough so inline and a regulator may be a necessity. also forgot to mention im running a stock hei with msd 6a box

Also ill apologize ahead of time but the more and more i go to college and write papers the worse my forum typing and script becomes. Sorry Guys.

That is a very easy goal, and you should have no problem reaching that very quickly. IMO, I would go no larger than a T4 T66 turbo with .85 A/R. Precision makes a mean one, but its costly. Could find a decent ebay turbo to match that size, as well as a decent ebay wastegate to compliment it. As for the cam, keep it within the range that you need, as well as your budget. I would go with this one, not need to go too big, Click Here. Be sure to smooth out the intake manifold, the less obstruction the better. Fueling is extremely important at this point, do you prefer an intank pump, external pump, or would you rather convert a mechanical one to rise with boost being that boost will be kept to a 8-12psi minimum...?

Master power T70 in a .96 is popular cheap and easy to find. Try to snag one of them. Magnum makes the new master powers and are better designs but 700-800$ now. Not like it used to be 550$ each.

Ebay gt45 may work too.

iTrader: (1)

i was looking at the gt45 ive heard good reviews on it and i have a friend who swears by them for his DSM cars. i do know a turbonetics/precision dealer i can see what his cost on turbos is if i know what kind i need

as for the pump could i go inline since now i have a mechanical and just block that off?

would i be best off piecing everything together or going with a premade kit?

Alot of guys use inline bosch 044 pumps on efi builds. Carb would need lower pressure pumps, the 044 would be overkill at that point

i figured, ive had some experience with tbi and i have an in tank type one laying around but would that be something at the operating range id be looking for and then an adjustable regulator? or is there something more apropriate out there

I have another Tuned Port Injection setup lying around with 30-lb injectors if your thinking fuel injection, those injectors will cover you up to 15-psi and should be good for 11's in the 1/4. I even have a 7730 ECM with prom and G1 adapter, could run the $59 mask if need be, although I would highly recommend the EBL-P4. Getting rid of a lot of stuff either way...

I'd be interested in turbo stuff but im pretty decided on staying carbd on this car for now

Street Lethal

iTrader: (16)

I'll see what I have left regarding turbo parts when I get back...

Carb will work well for you, just keep an eye on and monitor those O2's...

tylercamaro

iTrader: (1)

I don't have any o2's

Street Lethal

iTrader: (16)

... meaning when you get your wideband, you need to both tune and monitor the O2 in your exhaust, even more so with a carb because you can't target your AFR electronically, and you won't have any error correction without EFI. You'll essentially get an assortment of jets, and add/trim your fueling dependent on what your O2's are telling you. You don't need an ECM to use a wideband.

Gotcha ill cover in that later. I need to start gathering some stuff.
What is a blow through setup?

Orr89RocZ

iTrader: (20)

Blow thru is a carb setup that gets boost pressure blown thru lol instead of sucking atmospheric air thru a filter lid like most na carb cars, boosted setups force air thru carb. So they need modifications to handle such conditions

tylercamaro

iTrader: (1)

Does anyone have a diagram if how its set up?

Street Lethal

iTrader: (16)

Don't waste your time, send it in to have the modifications done in relation to your mods, as nine times out of ten they get it just right for you out of the box. Explaining it with diagrams will just get you frustrated. Let the pro's take care of it for you, it's worth it, believe me...

take it to a shop for the whole turbo build? um no

Street Lethal

iTrader: (16)

Umm Tyler, I was referring to the blow-thru carburetor.

datraum

when I do my turbo setup next winter this is how I will be setting up my blow thru carb. I will only run about 8 psi though and I don't want to spend $800 to $1000 on a new carb.

http://www.hangar18fabrication.com/blowthru.html

I found it on a turbo forum and a lot of the guys over there swear by it.

Street Lethal

If you can tig-weld it would be easier to just build a carb enclosure, but the linkage is very tricky, needs to be precise. There are guys running vacuum secondaries with boost and carb enclosures for that matter. The above link may in fact work well for you, but I never tried that on any of my old boosted carb setups, so it's hard to critique on my part...

i was gonna say if i let them do everything it takes away the learning curve =(

i got ya though. anyhow ive been reading up on that cam, and it seems to be right where id like to be with some room to grow later on. now as for turbo, BOP, Tubing, Intercooler etc etc whats recomended? what size tubing, i mean i can go with pieceing together some ebay stuff as i know some people use it but ive read that one thing may be gold but the other not so much, so id like to rather piece it all together to get a better finished product.

also how much added fuel pressure am i needing? i saw a posting on the classified here for the whole setup i was gonna look into. nothing special really just some summit stuff and maybe of the shelf pump and what not.

as for the 02's they come after the turbo correct or before? i vaguely recall them not being on the downpipe to the exhaust.

I know everything here is crucial, gearing, stall, cam, turbo. jst trying to get an understanding of what i need to look at so if anyone has some speicifc links or descriptions of how something works that may help alot as im a better visual learner. in the meantime ill continue searching around the turbo builds on here.

Also i never had a th400 car, what gearing should i look for? i have a few leads on a couple 8.8s i think one has 3.42's, 3.73s and one has 4.10s. all disc brake, and posi.
