mookandairin This thread is OLD as DIRT so I will answer for the sake of someone looking for more answers on the net. If you are going to be using a gen 1 ( 010 ) block you should "O" ring the thing but some MLS gaskets will work for the heads. get the block "decked" to zero after you get your rotating assy.heads are that big of a deal. get some world sportsman 2's, A blow thru is the most expensive part as I spend 1400 on my CSU blow thru carb. I built the same thing you are trying to build and made 850 Hp on a gen 1 block. I would if I were you is to get a ebay kit for entery level. for 14oo you get everything you need minus a carb and piping for the intercooler which you get one of them too. read the book Maximum Boost by Corkey Bell to get an idea on turbos then got to turbomustangs.com for the fill in info. my motor I built goes as follows.30 over 010 sbc, world sportsman 2 heass 64cc. forged internals SRP boost pistons 8.5:! compression, 850 csu blow thru carb.torker 2 intake running pump gas 93 octaine. GET A MANUAL BOOST CONTROLLER to adjust it as needed. the ebay kit comes with one of them too good luck

OldSkoolPala Well the post before mine was yesterday, that's all I seen, my bad, don't care about the date either...

OldSkoolPala Speed-Pro makes a nice nitrous/boost flat top piston, there not that bad on price either... And I'd look into GT35r ballbearing turbos, I have one on my Talon and thinking about boosting my Impala.. Sounds like it should be a cool build.. Good luck with it

TurboS10 Depending on your build skills you can build your own kit for less money. However, picking the right components and making it work together takes time and research...ALOT of it. I have done a couple of these one off's and they are tons of work. I would suggest getting a kit if you have deep pockets, dont have alot of time, alot of patience, and good fabrication skills. I can help with some build specs, but in the end you will have to do your own research to have any level of success tuning it and keeping it together.

banks kit for less HP goal??

i am looking to do a sbc twin turbo kit... im not looking for crazy numbers i just want something "different" under the hood...my z28 is my daily driver so i want something that is going to last... manifold design i could care less about... i just want 500-700 RELIABLE HP...

here is my set up so far
dart shp block (383 ci)
speed o motive balanced & forged rotating assembly
AFR race heads (fully machined) 72 cc chamber 8.5-1 comp ratio
1.6 rockerarms
no intake or carb but im thinking 2000-5500 rpm range so edelbrock rpm intake
750 blow thru carb (didnt buy it but ik i need one)
undecided on cam
gear driven timing set

i dont want to build something some one has done over and over again IE a blower sticking out of the hood

basically i just want a no complication bolt on twin turbo kit
the banks kit and wrenchrat kit are about the same price and seem to be quality kits

my question is would they be good kits for my goal or should i make my own kit????

383chevy you must drop the compression if running a carb on this setup. Get some gigantic injectors and build it well and it should be okay on 9:1. Intercooler, water/meth inj, timing, and tuning tuning tuning. The carb I don't think will get you there without a few surprises.

... my question is why aren't you just buying an lsx so you don't have any doubts or headaches or waste 10,000$. Seems like you have the money to me.

twin turbo

if your lokking into twin turbos www.wrenchrat.com makes good set up's for blow through carb set up's. i personally love the header design! If your looking for a cam look into comp at the nos and turbo grinds. most lower ends won't hold that type of power, but scat makes some good forged cranks. me personally i have my dad getting mine made from some one in wisconson, its the same one that is in his sprint boat. rods go with h-beam but not EAGLE! I used them when i turbo'd my accord and bent one and a week later one blew a nice hole in the block. so manley was a better choice. Dart or APR would be a good way to go. compression ratio between 7.5 or 8.5 would be better then the 9.5 remember this isn't a honda. i would look into a dry sump setup with the turbo's as well. t4 is kind of small i would look into garrett gt42r-gt60.

TT Trans Am GTA I know this thread is old, but for the power you want go to nelsonracingengines.com.

SBC S-10 Yea, I saw Banks on horsepower TV and wasnt a fan of his setups, just didn't like the way he was doing things.

Anyways, twin turbos may not be the route to go with this car. It's my friend I'm asking for, and he's going to be putting a C4 style rear chassis and what not in there, so it will be able to hold up to alot of power, but maybe not what twin turbos will give, the initial plan was a wild nitrous motor, and then we started talking turbos and how much potential they have, because I used to have a talon and those things can make some insane power with a turbo for a 4cyl.

Looks like nitrous might be the way to go, his heads would be perfect for a nitrous motor, just need a new cam and bottom end and it would be set for spray.

Thanks guys

TurboS10 Actually the kit says 5-800HP from what I saw on the link. The complete engine says that it will handle 1100HP or something like that, but I just dont see it making that much. I have never seen or heard of a banks engine making anything even close to 1000HP, but then again, I have never heard of anyone buying one either so who knows. I am just not a big banks fan. I think that they are severely overpriced for the power output.

I totally agree on the stock block for that much power. Hell, I figure mine is a ticking time bomb at 700HP potential(if I ever get it setup right). I also think that some big Dart heads are a good choice as well. That is why I bought mine. They flow enough for 550-600HP NA so under boost the sky is the limit.

That is a thread over at Thirdgen you might find interesting. You might be able to contact the author and ask him for specific details and whatnot on his build.

Rick WI Let's look at a couple of things that might make this somewhat impractical.

First of all the drivetrain. Even with 500 HP to the wheels in a Vette your going to tear up the rear and half shafts. 1000HP to the wheels, which puts you in the 8 flat 1/4 area at over 160 by the way, will destroy all things connected from the frame to the ground.

Second, just setting a body on the frame of a Vette will flex it considerably, having done and doing restos on these. A 12 point would be manditory for track purposes and manditory just to keep the car from twisting and breaking in two.

Third, I don't think 1000 HP to the wheels in the same breath as ZZ block nor Fast Burn heads. I think Dart block and heads that will flow 330+ on the intake and 250-260+ on the exhaust. With very thick deck and o ringed.

With a project like this you'll be crappin $1000 bills. I'd suggest setting aside around 30 to 35 of them to build the car correctly.

coldknock Not that I disagree with you but the company website disagrees. They state "in excess of 1000HP" concerning the 366" engine they sell. They even have a graph showing over 1100hp. It is worth noting that that state 100 octane fuel and an intercooler was needed to make that much power. With their reputation at stake I don't think they'd make false claims and place false ads.

With that said, I agree that it's easier with larger turbos, more boost, less compression and a big intercooler. However, I don't care how easy a turbo is on the rotating assembly, a stock 1st generation block will not handle that much pressure long enough to enjoy it. I doubt it'd last long enough to tune it for that much power.

We're talking about rear wheel horsepower right?

1200-1400hp at the flywheel would get you over 1000 at the wheels. It's a very different ball game when it's in the car. Yes, I agree the Banks kit won't touch that.
