2g intake and MAS assy. onto a 1g?

[forcefed86]

I have a 96 GST parts car down the street from me. Guy is willing to sell me the entire intake assy all the way down to the turbo w/ the MAS for 50 bucks. Will this simply bolt on the my 1g? Or do I need an adapter pipe like dejon sells? I know I need to make an adapter wiring harness. Just asking if it physically fits in the 1g space and couplers will bolt up.

Also the 2G MAS flows 33% more air than a 1g. So if I were to go with 650cc injectors, would I be pretty close to in the ballpark with my tune. I have an AFPR and a WB02 so I can play with the tune a bit there.

Usually people (myself included) run a 2gmas with 550s without much a problem, mine actually runs rich according to fuel trims.

But as far as fitment goes.....it will fit, but it won't be easy or fun. A small filter will help tremendously, but I had to do some hacking to get everything to fit because I didn't have time to wait on a filter since the talon was my DD at the time. Many people have done it though, and many have said that it can't be done, so I suppose that your determination is the key as to whether or not it will fit .

Well, I'm pretty handy with a cut off wheel and a welder so I think I should be ok. Any threads on guys adapting the 2g MAF to the 1G air can/filter setup?

For another 75 bucks I could run the DSM chips 3gMAF good for 500 hp. By my math the dsmchips 3g maf flows 43% more air than stock. That would come out to (629cc's roughly) Since the injectors are flowed at 43+psi I figure I can just lower my base fuel pressure a bit on some 650cc injectors and I'd be set.

I haven't bought anything yet. I'm just trying to match a larger MAF to a set of larger injectors to avoid having to buy the socked ECM/chip.

Fits just fine even with the huge 2g K&N FIPK. The hardest thing is going to be rigging up something to recirc your BOV with. I just used a 90* PVC elbow and some rubber tubing.

Project I don't know how you got yours to fit so easily, I had to do some serious hacking, and I thought that the 1ga and 1gb frames are the same so that shouldn't be it...idk.


As for the fuel setup it sounds fine lowering your base fuel pressure, but I don't think that's really what a 3g/evo mas runs, I thought it was a little lower than that but idk, could def. be wrong.

Really though what are your goals? Throwing in a 3g/evo mas will raise your timing considerably causing the car to be more knock prone (which you could semi-correct by raising the fuel pressure)

It all depends on your end goals really, if you really don't want to get link or a chip and don't need to go bigger than 550s then get the 2gmas, if you'll need bigger injectors then get the 3g/evo mas.

Just remember that most of us have changed our goals since the beginning , I came onto the seen wanting 300whp, then 330, now I'm aiming for 380ish, hopefully that will sustain my fun, but who knows.

In short though it really is better to wait and do it once, I now have to change my fuel pump again because I skimped out the first time and since my goals have changed I can't run e85 on my 190 at the boost level I want. So my recommendation is to go big. Get the 3g mas, get injectors that are 30% too big for that mas, and run e85, easily giving you the opportunity for 400whp or more. (Look at member on here jrhoner 's profile, 750s, e85, evo3 16g, 414whp)

Eh your right I wasn't thinking of the timing tables. Are U guys running chips to deal with the higher timing from the 2g maf?

With the 2gmaf and alky injection I could probably get away with the higher timing. I already have the AFPR, and 255hp walbro. As well as a 7gph alky injection kit. I'm just looking for the cheapest way to run 20lbs without detonation.

This is strictly a daily driver. I've got other "toys" I planned on dialing it in at 20lbs and being done with it. No e85 or 70mm turbos for this one.

With the stock 2g rubber intake pipe you have a lot more leway and can compress it a little bit to make it fit in there. The only problem I have run into is that the popup light motor arm hits the front of the filter depending on how the filter gets positioned. The frame is the same on the 1ga and 1gb as far as the headlights are concerned. Actually without the light motors you 1gb guys probably have more space.

The only thing I can think about that would make you have less space for a filter would be the SMIC piping going to the fender well. While mine is short route. Although, before the short route, I was still able to get the filter to sit in there, but it definitely was a lot tighter of a fit.

If you need a lot more room to fit it in there and want a nice hard intake pipe look into Dejon powerhouse's 2g in a 1g pipe. It's a lot shorter than the 2g aftermarket pieces and should make almost any filter work with ease. Here's what it looked like with a 1g K&N filter and the Dejon adapter on my last 1g.

I built my own intake pipe using 2-45deg. mild steel bends welded together along with couplers and welded the small stock pipe for the Bov onto the top of the intake.
Not too hard but just takes time. Next time i think i'll just by a Dejon intake used off ebay.

No chip here, no tuning devices whatsoever, not even an afpr, I was getting away with 21psi on my 14b with 7cm turbine housing still running the stock sidemount with no knock in 75* or less temps. You'll be completely fine with alky injection.

I found a great thread on the 3gmas http://www.dsmtuners.com/forums/tuning-engine-management/325191-evo-3g-mas-2g.html

Looks like it will throw timing through the roof though.

Thanks, I'll go ahead and pick up the 2g Maf assy down the street today then.

I run a 2g MAF and intake with a 7gpm alcohol injection kit. With 650cc injectors, 190LPH fuel pump and 91 pump gas, my e316g happily boosts to 25 psi with no knock. Injector duty cycle is 85% max. You should be perfectly fine at 20 PSI with the alcohol injection.
