500hp

[bojanglesracing]

Ok i 'm starting on building a new motor for my 91 talon tsi. I want to build a motor that some where around 500hp. Now i have a frankenstein level 3 turbo. Now what i would like to know, what should i do to the motor to reach my goal. Thank to all those who help.

 

[drewvr4]

your going to have to do internals...most likely head work but opinions will vary depending

since your car is a 90...you have alot of work and money to reach that goal

 

[Scott_S]

You could get 500hp from the stock internals but probably wouldnt last to long. If you have the money get some je forged pistons and eagle rods or something otherwise 1g rods and 2g pistons

 

[bojanglesracing]

Well the car i am bulilding is a 91. I am just looking for idea of what to do. Like what part would help me, cam, piston, and such.

 

[bojanglesracing]

hey thanks scott

 

[mn95TSi]

just for asking that question i don't think you will be seeing 500hp any time soon.
search, before someone else tells you.

 

[Scott_S]

you will also need cams, I'd do 272/272. a walbro 255. 800cc injectors more or less. fmic. and probable more

Go to dsmporn.com and copy scott grey set up or call Roadrace and ask them what they would do and what parts they use to achieve this goal. Then find copy what they do word for word BUT just get the work done somewhere else because they will rape you on labor. They tried to charge me 1600 just to take the motor out!

 

[gottalovenewage]

drewvr4 is right. but as long as you have forged internals, a completely reworked head/cams/etc., and a standalone to help manage it, i dont see why your motor cant handle the amount of power your wanting. the only thing is getting it there after that

 

[brute]

Someone made 590whp on stock internals... the 4g63 is a beast. You don't really NEED a built motor unless you are planning to run 30+ psi and/or NO2. If you are using it as a daily driver or racing a lot, the stock internals won't hold up for long so you'll need forged internals.

 

[Trucloner11]

You better look into a new tranny too...its only good for about 4oowhp

 

[92_talonTSI]

Tranny good till 400 boy I wish I could find one of those I done small mods and have went threw 3. Plus my buddie in his 2g has junked 4. Im getting ready to build a 6 bolt for my 95 im going scat rods and manhle pistons bore .20 over port the head and hks or buddy club 272 cams. I was able to save my venom kit out of my totaled 1g si plan to spray. good luck

 

[bojanglesracing]

Hey thanks guys. That what i wanted to hear. Some people were telling me that i had to do a whole lot to get 500hp. So thank for you help.

A turbo that will support 500hp fmic bigger injectors than your 510's a walbro255 afpr a way to tune those big unjectors since ou already have a safc I would just get a chip and you should be good to go unless you have the doe go dsmlink or EMS. All that and then the knowlege to know how to squeez 500hp out of it cause if you can't tune all those parts won't mean anything

 

[dsmturbo111]

your going to need internals....also cams...500 is pretty high your going to need a lot of work

WRONGGGGGGGGGGGGG


People have made 500whp on stock internals and cams are great but def not REQUIRED to make 500hp

I've heard that some people have gone as high as 600 on stock 4G63T internals, but that doesn't mean it isn't smart to rebuild with upgraded internals if you have goals that high, imo. Just because it has been done, doesn't mean that anyone can just slap some shit together and make it happen.

Basically, if someone is aiming for 500hp and above, I would think they'd be considering the benefits of putting the screws to some better internals. Why aim for the top, power-wise, but then pinch pennies and half-ass how you get there?

You're right. People have made big power on stock internals. Would it be a good idea to plan a build that included aftermarket internals? Some people think it's needed for better reliability. Why gamble at that level?

 

[1993eclipseGS]

You should also look into a built tranny with an LSD , All the suspension mods etc.. You have a fwd car. I would aim for something lower then your 500+WHP goal. Did you ever have even 300whp? I'm not arguing i'm just saying in reality. Also, Where did you get your goal of 500whp?

From what I remember a Frank Stg 3 uses the less efficient 54-trim T04E wheel.
From a Honda ( ) board I'd bookmarked:

Common T04E compressors:
40 trim (36 lbs/min)
46 trim (41 lbs/min)
50 trim (47 lbs/min)
54 trim (45 lbs/min -- note that the 54 trim flows less than the 50 trim)
57 trim (49 lbs/min)
60 trim (50 lbs/min)

Could prol still make 500HP at the limit, but may want to start off with a larger turbo

 

[DSMJim]

Very few peopel have ever made 500whp on stock internals without cams. You will need a cam or nitrous for sure. Turbo only power, 500whp on stock cams is gonna be hard if not damn well impossible. Yeah its been done, but that doesn't mean any of us are gonna do it.

With out cams to make 500whp your gonna need nitrous to get there. Otherwise your gonna have a hell of a time with a GT42 at 35psi on race gas...

I am not one to contradict wiseman no matter what they're specialty as I am no wiseman but my buddy who has been helpin me build my car had a 1g awd that went 11 flat and made 500hp on stock internals and raced this car constantly and dd it. SO while I understand how you and luda say that the added security of built internals is smart the other poster said it was needed and I know this for a fact to be wrong. Not to mention this is a 6 bolt not a 7 bolt and everyone knows that 6 bolts have been known to handle more power. A set of 1g big rods with 2g pistons and maybe if your really worried a set of arp rod bolts will hold 500hp.

 

[GreenGSX]

If you can tune a car to run without knock and there are no hidden defects in the crank/rods then 500hp is possible.

The real issue is how good a tuner are you and how much are you willing to risk. Even at 400hp a mistake can be fatal and when a stock motor lets go it isn't pretty. They normally take out the block, rods, and crank turning your motor into junk.

So, if you want to make 500hp and you have to ask what you need to do it then I would suggest either taking step back and reassessing your abilities or plan for the worst and build a motor that can take some abuse.

Here's what I would do,

6 bolt block
Crower rods
Wiseco 8.3-1 pistons
A good set of cams
bigger turbo

Was going to add check the Tuners Dyno Database and see what others are using on their 500+ HP cars, but see it's currently down for maintenance

Lol Jim where the hell did you get gt42 at 35 psi from Cams are a huge help like you said but they are not needed. I mean we could go and say he's gonna needs dsmlink or ems cause not many people make 500hp with safc or that he needs a smim because not many people make 500hp with a stock mani or that he needs a turbo that's rated to 600 hp cause most people realisticly make 100hp less than the max hp ratin on a turbo, you guys see where i'm going with this?
