Hey guys, i am in a toss up about what to do with my Camaro. I want to have a solid 450hp to the wheels. I know for a fact this can be done with a set of aftermarket heads, cam, intake etc, but i also know it can be done on boost.

I was looking at going with the Trick Flow Alum heads, as they are a very good bang for the buck, going with an HSR, headers, cam, etc. Already have Megasquirt so ECM is not an issue.

Then i got to thinking, a Turbo 5.7L is just wayyyy cooler than an NA. I already have a welder and have some prior fab skills from working with my Turbocoupe. I would probably just do some Weld-El headers and throw on 2 T3's with internal wastegates, this should easily net me 6-7PSI of boost which would yield a fair ammount of HP, this coupled with some portwork to my existing heads, a turbo grind cam would get me to my goal.

I love doing to DIY work, so i really like the Idea of a turbo setup, i know how everything works and i already have a HUGE 32" "Ebay special" intercooler.

I almost have the money to buy the Trickflows, but i am really un-decided. Ive already done a ton of research on how to turbo these cars, overall its pretty simple, nothing rocket science.

Tell me what you guys think.

 

You seem to have a decent grasp of turbo charging basics, with the fab skills and tooling, it sounds to me like an easy choice.

Remember, a high HP NA motor is VERY hard on the motor, since you have to rev it up really high. Also that means a big cam, which kills driveability, mileage, etc. I would think maintenance would be high, but I think it'd be about the same for both.

You've already got the HSR and megasquirt, so I think that's a great base for a turbo setup.

In short - Turbo. Not sure what heads you have now (stock L98s?), but you may want to have bigger chambers. Perhaps some chamber porting would drop you down suitably, save you from having to get new heads.

 

I had more troubles with a turbo'd V8 than any N/A setup.....there is something to be said about N/A and Cubes....

 

Yeah, i think im gonna go with the Turbo route. I already have the fab skills, Megasquirt and some New 38# Injectors. Just need a 255lph intank pump and i think i would already be set on the fuel situation.

I just cant decide Twin or Single turbo, i think a single turbo would be cheaper and also be more effecient if i chose the right one. I am thinking a single Remanned Holset would be an excellent choice. I know in the Turboford world they are very very nice turbos, can support huge HP yet also spool pretty quickly.

I just need to research if a large single turbo will easily clear the stock IROC hood, as i dont want to go aftermarket, i want to keep the semi-sleeper factor. I think it will be a huge suprise for all those Hillbilly Reddnecks are the track with the same-old played out carb'ed smallblock build. (No offense to any carb users) <3

I also forgot about the MPG and Driveability factor. A turbo motor generally uses Low-Duration cams, this will keep low end torque high and improve mileage when off boost. High HP N/A motors must use insane cams which kill torque and milage, but boy do they sound nice!

 

Exactly! But a turbo spooling up or blowing off sounds pretty cool, just in a different way... The way that you have to know what that sound is to "get it". So the hot girl on the sidewalk will think there's something wrong with your car, but think the guy next to you with the lumpy cammed mustang has a nice sounding car, but who's faster? mmm hmmm.

I prefer the twin turbo route myself, but single a turbo would probably fit under the hood easier. You can put it where the battery is almost, nice and low.
Anyway, good luck.

 

Turbo, you know why.

i don't think you could make 450RWHP with stock trickflows anyhow.

 

Probably at the flywheel, but not at the wheels for sure.

Those Trickflows flow pretty good, they keep up with the AFR's up until past like .550 lift or something like that.

 

also on a test enigne ( in the TPI board ) CHP used them and they out perfromed the new AFR eliminators all the ay to like 4700 rpm
