custom 2gnt parts ???

Bigrand found out anything about the bezel yet?

In clueless about the ECU, but I wanted to chime in on the IC piping.

If your guy is making the manifold, the turbo would be in the same place on every 420a, therefore, you would only need minor modification for different turbos, like a custom J pipe, or some kind of flexible tubing.

Also, I had this idea a long while ago when I was thinking about turboing my car, and before I actually got into turboing my car. Maybe making some type of flange thats bolted to the 420a, to make the exhaust manifold from a 4g63 bolt up. I am not sure how this would work, maybe having a 1/2" flange, drill out the 420a exhaust holes, and drill 1/4" of the flange out so the bolt would sit inside the flange, I will try to draw a picture to explain this I know it seems confusing. I was going to try this, but I lack tools to do any metalwork other than a dremel for light cutting and a cordless drill . Ill make a pic and post asap.

heres a pic in paint, its rough but I think itll get my idea across.

I have both bolt patterns for the 420a and the 4g63, not to scale.
the lower right shows how you can drill out of the flange to make room for the head of the bolt, so the bolt will sit inside the flange, and allow the flange to mount flush against the exhaust side of the head. This would be the cheapest alternative to making manifolds. If you want to take it a step futher, you can weld in the bolts for the 4g63 side, so basically, when a user wants to use a 4g63 manifold on the 420a head, they will bolt up this flange, and the bolt pattern will be changed to the 4g63 one. This provides a user with a much wider range of manifolds for the 420a, including the stocker which has been proven at the track when ported.

As for the turbo side, you can also make a flange to change from the mitsu to a t3/t4 or whatnot. If priced low enough, I believe this will sell like crazy since the user will not need to purchase a new manifold to switch from mitsu to garret to turbonetics or w.e

napkinthief, i tried that flange design when i made my manifold, and found it alot less of a pain to just weld the flanges together as you can see with my use of the 4g63 manifold.

ps. didnt mean to hijack the thread, just thought id throw in my 2 cents...

Yeah its gonna be $80 for the bezel, I have to bring him my old vents so he can make a mold out of them. I'll find out how long it'll take him to make it, but I'll bring him what he needs to make it tomorrow.

Where would I be sending it to...PM me the address, if it wont' cost that much I'll probably cover the shipping.

Hahn makes one of those to convert the Mitsu flange to the T3/T4 flange, it works in reverse too.

The other flange adapter is a good idea though. I'd like to see one of those come into production; I think he could make quite a bit of money, not only with the 2GNTers, but the Neon guys too. It seems pretty straight forward to make too, if I'm understanding your design correctly.

The only design element to take into consideration, though, is that there isn't a whole lot of clearance between the turbo and the radiator as it is... so this would need to be pretty slim in order to work properly (unless you get some slimline fans maybe).

UH bigger problem.....If understand correctly what you want to do is make an adapter plate so the 4g63 manifold can be used on a 420a. This has been done for 1 but look at a 4g63 manifold. The turbo sits far to the passenger side. With this manifold the turbo DP would be right against the P/S pump.

Like i said i saw it done but the guy welded the bracket to the manifold. If you are familier with welding into cast iron, there are many precautions to take and it is not always guarneteed to hold. I have welded into cast with good results but they were never used long term and it was an incredible hot amount of prepwork.

Yeah I can vouch for how big of a pita it was to get that manifold to work. Welding cast sucks also. I had to put it in a blast furnace like 3 times during the process so it woudlnt crack. It doesnt bring the turbo that close to the power steering pump, but it does make the ac have to go bye bye. I actually made a bracket so that it would just bolt up, but if had clearance issues, due to the fact it had to be think enough for the bolts to go in far enough to support the heavy weight of the manifold and turbo.

 

[napkinthief]

Yes the stock manifold is cast iron, but there are countless other types of manifolds that are only available for the 4g63 engine, equal lentgth, tubulars, etc. It would open up the use of any 46g3 manifold for 420a guys. Yea the area is tight, but this flange would not need to be more than 1/2", and I think there is enough clearance for it, can someone confirm? If i had some tools to work metal like this I would give it a try.
