Default Short block or long block

If i was looking to re-build the internals of my engine for max boost for a turbo....which would i need to get the short block or long block....is it necessary to go for the whole long block...i am so confused...i know a short block is basically the block, crank, rods, pistons, rings,.....but do i need the long block?

wow...uhm...if you are going for max boost, you should seriously hit the books if you don't know that...

what you really need to do is get some low compression pistons and connecting rods and head studs, and then redo the valvetrain for high boost applications.

how much boost do you plan on running? what is MAX?

alright, take the time to lay out your goals clearly. what is your budget, how much power do you want to make, for what applications are you looking for? dragster, autocross, or a fun daily driver.

unless you are going to push more than 10 psi, you don't need a built motor so long as you use a stage 1 kit.

10g just on the engine itself, because with that kind of money spent on lets say a rebuild/turbo setup... gonna need some others things, just to name a few, clutch/flywheel, tires, lsd...

okay, that is extremly easy to do with that budget. first off, no matter what kit you choose, you will need the following: boost gauges, wideband 02 sensor for air fuel ratios (aem wideband is popular) and an egt or pyrometer (exhaust gas temperatures). now pick any stage 1 kit that appeals most to you because there are alot of them. zpi is great and has proven performance, and good 1/4 mile times, but you will get a cel, and have to remove the factory crash bar. the cel is only a problem if you have emissions inspections in your state.

turbonetcs is a good kit with a great warranty, but it has to be tuned by a unichip dealer/installer. they also have a 1 year no fault no hassle warranty, even if you race.

dezod has great kits perfect for daily drivers an you have alot of choices, especially with their signature kits. they also have great customer service and tech support.

dezod sells t-netics kit, and his kits with options like ceramic ball bearing turbos (very minimal turbo lag) and cat'ed downpipes (so you can pass inspections and guarenteed no cel)

the greddy kit is the lowest price, but you also have to get fuel injectors and engine management. it also doesn't have a very good track record in my opinion.

they are all good kits and can easily destroy a stock tc engine if not installed and tuned properly. it is all really a preference for brand name preference.

check out:

www.turbokits.com
www.zpiracng.net
www.dezod.com

there is also a turbo buyers guide sticky in the forced inductino forum.

on a side note. you don't sound too smart there with your ricky bobbie "i wanna go fast" statement there, and your obvious ignorant posts. if you are just some kid with a new license and new tc in the driveway, all i can say is walk before you run. learn to handle your car as it is before you completely change it.

also, don't sink all 10 grand into the engine and turbo, you need to balane the car with good brakes, wheels and tires, and suspension. a turbos only help you go faster, they don't help the car stop or turn better, especially at those higher speeds.

take some time, do some reading, and practice driving your car as it is so you can really get a feel for what you need, and what you want to suit your driving style.

Just because i dont know as much as you that makes me ignorant and not smart? Because i dont know about engines i am ignorant?....so i dont know what i am doing i go online to learn on how to make my car faster and ask a question about an engine and it makes me sound dumb?....and by the way....i aint no kid...im 26...just dont know ____ about engines or turbos etc...

well, you have no personal information in your profile, i just didn't wanna be responsible for helping a 16 yr old turbo charge his car get into a fiery car wreck killing innocent people imitating his favorite scene from fast an the furious.

the problem is the way you are wording your questions. usually only kids with the need for speed post questions like "what is the most powerful fastest most awesomest kit that will let me set single digit quarter mile times on my tc!"

the more mature folk who don't know poop about turbos usually ask "i am a noob to forced induction and would like to put alittle fun into my daily driver, what would you reccommend?" we get lots of those and i am happy to help, but when somebody asks "what is the most powerful turbo" it puts up a red flag that tells me this person could hurt somebody with a high powered tc and minimal driving experience.

if you search this forum, there are lots of posts and thread about kids crashing their scions because of bad drving decisions.

unless your buidling a dragster, there is more to a car than just going fast, if this is your daily driver, your going to have to balance it out with good handling and brakes.

so how about this budget, stage 1 kit is about say...4 to 5 grand, installation and tune is about 1000-1500, clutch, add about 400, clutch install, maybe like 750 (p-tuning told me that price for a clutch and flywheel install) gauges...uhm...500-600, install price included with turbo install usually,

then spend some good money on brakes like stoptech stage 2 brake kit, high performance pads, rotors, stainless steel lines for alittle over 600, most people install those themselves. then get full trd suspension, another say 800 approzimately from www.trdsparks.com installation, i'll say around 400, remember to get the alignment a week later after the suspension has settled.

if you are on stock tires, consider upgrading, because the stock tires suck, anything is better, i have kumho ecsta ask, alot of people like toyo proxis 4. www.tirerack.com or www.edgeracing.com or was it .net?

also note that turbocharged cars need additional care and attention. you should switch a synthetic oil, and get it changed every 3000 miles instead of 5000 like reguler tc do. you'll also need to use super unleaded 91 octane gas.

i think that should suck up your budget pretty well. now these are just examples, you should research these parts and see if they are right for you. but if you are running only a stage 1 kit, you don't need to build the motor, there are alot of people running stock blocks with stage 1 kits.

With the $10,000-$15,000, sell the tC and buy a ____________.

IIRC, didn't either Keisha or Kenny say that there was an option for a custom intercooler so that the crash bar did not have to be removed... I could have swore I read that somewhere...

*EDIT* I re-read the other thread and it was rhythm and Amo talking and looks like the answer was no...my bust

it used to say it on the website with their turbo kits. now i think it only says it with the stage 0 intercooler upgrade that you have to remove the factory crash bar. either that or cut it.

With 15 thousand dollars.... you're almost spending 100% of your car's worth into building a "fun daily driver." Never having driven a car with 15k put into the engine, I can't say for certain but good grief, that does NOT sound like a "fun" daily driver at all.

Regardless, if you have that much money to spend then spend a few of those dollars on the book, Maximum Boost by Corky Bell, ISBN 9780837601601.

It's a must-read if you're planning on boosting. It'll also un-noob you.

Fun daily driver on a fwd like ours is spending 5k or so and running fairly moderate to low boost. A fwd running on high boost is pretty useless unless you just want to go in a straight line.

Get a good reliable turbo setup (spend the cash to get gauges and proper tuning) and run 8 psi or less. That is more than you need for a fun daily driver.

In the end, FWD is a very poor platform for high hp applications, so if you want to comfortably drive it daily you want to avoid going for broke on power.
