Turbos and Superchargers

Re: Turbos and Superchargers

you are right. Doctorspeed aka G6Perfomance (original owner of G6P). he had the first CAB for the G6 as well. he came a went a few times after he sold the site off. there was some other issues with his personal life why he didnt continue with the turbo build and sold it off. as what happened to that turbo set up? who knows. it would only fit a 3.9L with the manual 6. one day someone will succeed in building a turbo or supercharger set up. its going to cost around $10k (turbo and tune only. does not include cost of trans and internal upgrades) to get it going.

$10k is a bit high. On low boost the 3.9 (8 psi max) will more than handle it with stock internals. If you go with a remote mount you will take away some of the tuning issues. Headers being one of them. Doing this wont be that much of a nightmare you just cant cut any corners when it comes to the install. I do plan on doing this by next summer. I have dumped a lot of money in trans work and now I am almost ready for boost.

8lbs on what size turbo are you thinking?

Re: Turbos and Superchargers

you still need to tune and if youre running boost youre going to have to run a full exhaust system to handle the added flow of gases. also you have the issue with the MAS (mass airflow sensor). theres a lot to contend with adding a turbo to a modern NA car with a MAS. you will also have to find a way to lower the compression ratio. I believe ours is like 9:1. when the Doc had his turbo. he was only pushing about 2lbs of boost. anymore they car went haywire with CEL's. as for 8lbs of boost, esh. I dont know if the internals can handle it on the 3.9L (just with the history of our motors having issues with them). Im glad you beefed up you trans cause thats our weakest link. a remote turbo setup is pretty much the only way. as there is very little room in the motor bay. so if you are going to do this best of luck to you.
here is some info that should help
227-242 hp @ 6000 rpm
235-242 tq @ 3000-4800 rpm
3.9L displacement
Aluminum heads, Iron block
Pushrod actuated; 2 valves per cylinder
Dual equal continuously variable valve timing
9.8:1 compression
99mm bore, 84mm stroke
FWD, hydraulic roller camshaft, roller rocker arms

Re: Turbos and Superchargers

On a smaller turbo 8lbs wont be bad. And a 9:1 cr isn't high enough to need to be lowered. Does anyone know the lz9's maf's limit?

Re: Turbos and Superchargers

Lowering compression for boost is a thing of the past now that tuning is what it is. 9.8:1 compression would be perfect, plus ontop of that the lz9 has oil swuirters for each of the pistons to keep the temps down in the cylinders. As long as you keep a moderate afr like 11:1 you'll be fine. Just have make sure whoever is tuning the car knows what they're doing.

Re: Turbos and Superchargers

I apologize if this is in here somewhere, but after skimming through 20 pages, I could only really see talk of a turbo setup. My question is, what about the S/C off of a 3800 for the 3900? I know the motors are different, but with the 3900 only being 100cc larger, could it not be possible to swap the top ends of the motors, and have the supercharger from the 3800 work with the 3900?

Re: Turbos and Superchargers

I remember something about you will have to have an adapter plate made to fit the intake manifold on the 3900 and supercharger from the 3800. also you would need a hood with more clearance

Re: Turbos and Superchargers

not to mention the fact that the 3800 is a 90* V6 and the 3.9 is 60* they have NOTHING in common parts wise or design lol

Re: Turbos and Superchargers

Another hurdle to get over with the m90 would be to moving the power steering pump, at least on the f40 cars it is.

Long and short. Close engine size...but no good.

Re: Turbos and Superchargers

So next year be prepared to be awed and shocked next year when you see a G6 twin turbo'd along with a complete engine and transmission build up. Pictures will be posted when it takes place and it will happen after I get back from deployment next year. I know its pics of GTFO but they will be up while and after it is all done. Got a shop ou there in KS that will be helping me throw it all together and write the programming for me.

Re: Turbos and Superchargers

And it isnt going to cost $7000 for the turbo setup. As of right now it is only going to run $3800 for the entire setup. Then engine and tranny hardening will run about the same then tune is a variable due to the fact that it could take a while for it to be done. I am not hack sawing it in the garage, I have been talking with people who custom build and tune everything and have been proven time and time again. So dont negitive comment. When it takes place you will know, that I promise you. Plain and simple.

^^^this^^^ sounds epic!! i really hope it works out for you and cant wait to see it unfold. i know for a fact alot of people on here will be counting on you now after that comment so you better be prepared to have...

but good luck makin that 6 scream!

Re: Turbos and Superchargers

JJT I couldn't agree more about the tuning a N/A car for FI being easy, honestly I've thought about running a similar set up as the other "guy" who went boosted but everytime I start to get into the set up the car gives me another hiccup and I have to take a few more steps back. I thought the issue was dealing with the VVT and Variable Intake Manifold we have.


Oh and there is absolutely nothing wrong with making your Honda faster instead of buying a GTO, and honestly I would probably perfer the Honda over the GTO. The reason the Civic guys have so much aftermarket support is because they have no problems shelling out the cash when parts come along. Dropping 800-1100 on an equal length long tube header is completely ok over there and spending anything less then 600 is considered antichirst. If we want that kind of aftermarket then more people are going to have to start bugging the smaller custom shops (like S&S before they went out of business) and acutally forking over the cash when push comes to shove.

Say it with me, there is no replacement for displacement.

Re: Turbos and Superchargers

Oh it will there are no worries about that at all. I am just waiting for deployment to hit so I can drop her off and they can start doing the printing and work on her and then coming back seeing her and taking her on the streets and the track. I dont care wtf anybody says it is going to happen and it is going to succeed.
