Hi I'm new here, and I've read a lot... That being said...

Ok, I decided to make the jump into SC now. And I'm debating over comptech and vortech.

Correct me if I'm wrong here, but the vortech is prob. the better of the 2 because it has the aftercooler. The Comp. although gives high HP gains once the engine and compressor get hot the HP gains decrease due to the increase in temp.

I have a friend who knows someone who wrecked his S, and he's NOT getting another. He took off the SC it's a comptech and willing to sell it for a good deal to me. But like I said I like the idea of the aftercooler and I konw the comptech he has does not have an aftercooler and I don't believe that comptech offers one either...

Anyway here's the question. Can you use a vortech aftercooler and hook it into the comptech SC?

I figure anything can be done with enough money etc... however Has anyone ever heard of anyone doing this, or do you know of any reason why it would not work ie they mount differently and would get in the way or the 2 set of electronics would not allow it to function...

All opinions on the subject are welcomed.

Thank you

Scott

EDIT:
I'm also intersted in any of the following upgrades if they are worth it... cam, valve, lifter, porting...

Thanks again

 

I'm not sure about the aftercooler question, I have asked the same thing myself and no one seems to know.
But, I would say if it's a good deal, get the comptech. I was in an almost identical situation as you and was able to buy my comptech for 2,000. That is a huge discount and well worth it in my book.
Back to the aftercooler, comptech claims that they have one testing and should be released by mid summer.....but i'm not sure i'd hold my breath. A few board members have made a custom intercooler for their comptech and it seems to work very well. I am beginning to look into that as an option myself.

The Vortech rep has stated to many members on the board that their aftercooler won't work with the Comptech. If you can get the Comptech for cheap and it is in good condition I would recommend you go for it. The hp difference isn't worth thousands of $$$. For the engine mods, several people have cams and think it makes a big difference. There is a 2.3L kit out there, but it is $$$. If you are really looking to drop cash & get max hp go for the turbo. Also the gears are a big help for this car.

 

I am running a Comptech unit and did a couple of things to reduce AITs:

1. Installed a Hondata insulator gasket along with Mugen fan switch/thermostat/radiator cap.
2. Made a custom air intake which breathes through a K&N in the nose.
3. Installed an Amuse style vented hood to lower under the hood temps (not sure how large the effect is).

I don't know what kind of AITs the Vortechs are seeing, but I am in the 120 range on the dyno with 7.2 PSI (4.25" pulley). On the road the hood and air cleaner should actually yield better results because the air flow will be much greater than the dyno's fan setup. Also, we did 3 runs with 2 minutes between each and didn't find much of an issue with heat soak - a couple of degrees in AIT and a couple of HP (it varied).

If you are going to do liquid to air intercooling, it would probably be just as easy to do something custom since you would have to butcher your current setup to make the Vortech aftercooler fit.

YS,

Mind if I ask what your WHP was on the 3 runs?

Thanks

I'm not looking to stir up the pot... but I feel the need to post my opinion. Please keep in mind that this is only that... an OPINION. That being said:

1) Comptech has done extensive R&D with specific regard to a handful of vehicles and actually owns at least 1 of each said vehicle. They make products specifically for those vehicles. IMO Vortech just took their name to use for credibility and slapped something together to make their kit. It is excellent with regard to quality of the components but that doesn't mean that it is excellent for this application. Yes the aftercooler is excellent however you can make your own (and it won't look "rigged") for probably $300-$350.

2) Cams... nobody makes cams with profiles specifically designed for forced induction for the F20C. If I am incorrect in this statement, please let me know so I can go get some.

3) Springs, et al... can't hurt. Bus regardless of what you do, don't loose sight of the fact that you're putting forced induction on to an 11:1 compression motor thusly yielding @ 7psi (give or take) an adjusted compression ratio in the area of 17:1. Be prudent with the order of your upgrades if you're looking to "build on" one of these kits.

4) Porting / airflow in general. You will notice that increasing the efficiency of the airflow in a forced induction application will yield greater gains over that of an NA engine. If you're going to port the head, you need to match the intake manifold and TB to really notice the benefit.

And that's all I have to say about that...

As Jerry P said....Make sure to get the crank pulley off the wrecked car as this is an expensive piece to buy from Comptech.

 

The Comptech SC is nice because it's designed to be installed without making permanent modifications to the car. I like the idea of something that can be removed from the car and then returned to stock. The Vortech requires tapping the oil pan for an oil source, and so you'd have to replace the oil pan to return the car to stock.

The Vortech unit is nice of course with the aftercooler, but it is true that Comptech is going to release an aftercooler of their own.

All in all, Comptech is a really stand up company. They've been working on Hondas for years. I believe in their products and I would trust the craftsmanship.

One downside to the used Comptech SC is that Comptech will not warranty the kit once it's been sold to another person.

If I were in your shoes, I would jump on the used Comptech and then either hold out for the Aftercooler or custom fab your own setup.
