What kind of turbo

[badpie426]

ok im in the process of shopping for what turbo im gonna use. I have A B18C5. 9:1, FOrged pistons and rods good for 700hp, Darton mid sleeves , acl race bearings, arp studs, At the moment stock head for now, hondata. It is a dd and ill prob have it at very low boost most of the time like 8lbs but deff want to put down 5 to 600 hp when needed. I have no idea what kind of turbo to get, i dont want to big cause of lag nor to small cause itll restrict power. Im not really trying to spend more then $1000 for the turbo. Also what size exhaust would be recommended. 3'' 4'' or 5''

3" exhaust is plenty. You have to understand you're not playing a video game. Set a REAL goal. You can't say oh I want to daily drive with 200hp and then flip a switch and get 600hp. 600hp is HUGE power goal. Especially for an INTEGRA. Daily-driver, I think not.

Let us know when you grasp the concept of forced induction and have a real power goal. "8psi" isn't a goal whatsoever- 8psi on a tiny turbo will not be the same power as 8psi on a large turbo.

U can do exactly what I'm talking about . I just need to have 2 different MAps loaded into my Hondata one would be for just driven around an one for racing .

This is why I'm looking for a turbo that's kinda I'n the middle .. Tuning will take care of the rest

Yes, I know that you can switch out the maps on Hondata. However your setup has to be built to support 600whp. You can't make 600 on a stock head. New intake manifold, probably port and polish, upgraded valves, valvesprings, cams.. Another thing to think of is fuel. Yes- you can obtain 600hp on pump gas, but it's just that much harder. Running 9:1 comp on pump gas, you're probably going to need a good size turbo to actually hit 600hp.

What kind of numbers are you actually looking for? You want to run around with 200hp and 33mpg on the streets, flip a switch and get 600hp just like that? Are you looking to go from 400hp to 600? 550 to 600? Give us some real data to work with here.

More like 400 to 500

You can make 600hp on a stock head Kris, but thats not really important. What is important is the OP needs to learn more about turbo's before making goals. You want huge power but don't want lag, well my man you can't have both. You gotta give up power for less lag and vice versa. Personally I like Garrett's 60-1 (good to about 500hp) or Precisions 6262 (good to 700+).

The problem with most people that post up they want 500-900hp is they have no clue just how expensive it is to make those numbers and do it reliably. You haven't mentioned what type of fuel system you plan on running ect...

As for exhaust 3" will work just fine

 

[Tam4511]

Yeah once you go past 500hp the price of the build goes up exponentially.
You'll have to get a dual fuel pump setup and a hangar, big ass injectors, up grade all of your fuel lines, fully build the head etc.

 

[badpie426]

I think I'll just stick to 400 to 500 hp range . It deffinetly seams more practical for my budget an I'm sure I'll be happy with the outcome ... I'll save the 700 hp build for when I have a real job

Josh, what are you referring to as a stock head? I have NEVER seen a stock head hit 600hp. Are we talking stock like "It's a stock head that was ported, with a new intake manifold, new cams, new springs, new valves." because when I say stock.. I mean "Stock like it just came off the assembly line."

Build links if possible? I'm curious about this..

And yes- Josh and Tyler are both right. It is God damn expensive. What exactly is your budget? I have a 600hp build in the works, and i'll probably have at least $20,000 into the car before it's done.. The_Guy_From_Nerk has high horsepower build and if I recall he has like $40,000+ into it. (Could be off on that number.)

 

[DaddyBuiltRacing]

No I am talking like bone stock head maybe a valve job. The vtec heads flow well enough from the factory to support big power. The reason most people do headwork is to eliminate having to run the extra boost pressure and saving the life of another part of the motor. Most people don't bother with port and polishing mainly due to the cost of it (500+ in my area).

Look at this guy for instance, over 600whp on stock everything head wise lol.

Thats just a 20 second search, I know there are countless others. Notice though the guy has a t67 turbo which are known to be laggy, a port and polish should help spool the turbo a little bit quicker. Then again higher compression would help spool that thing too lol.

This was in another thread on Jeffs website posted by Jeff Evans himself "by boosted hybrid » February 2nd, 2008, 9:23 am

"Dont know if the head was ported or not, but i have made close to 800whp on stock port heads. Porting helps, but isnt necessary for making big power."


BTW I have 20k wrapped up in mine

 

[Prozon]

40k seemed too high. 20k seemed too low. I was going to say 30k but I just couldn't remember lol.

 

[DaddyBuiltRacing]

Haha, now I will prob end up having 40k in the damn car after shit starts breaking and I have to replace stuff. Hell I will have another 1k in a clutch alone this spring, then you gotta figure in roll cage, gonna do brakes, bushings, ah it never ends!

 

[Prozon]

Bushings shouldn't be bad. Energy Suspension sells a master bushing kit for like $140. It's just the labor to put them in lol. Thank God I had a press.

Shit the kits are easy to install, between me and my dad we've done over 10 master bushing kit installs lol. I have access to a monster press as well so that is always a plus. They aren't very expensive you're correct, but its the big picture where those little items add up real quick.

1000-1500 for clutch
150 for bushings
200-500 on brakes (depends on what brands I go with)
130 shifter linkage mod by RC Autoworks
100 TWM short shifter
350-500 for traction bars
200 for drag radials
400 for new slicks

Thats a quick way to spend 2500+ over the winter lol
