1g Holset users LOOK PLEASE!!!

[1glaserfwd]

Just wanted to know which intake pipe guys with larger inlet or holset turbos are using on there 1g. I was going to order the fp 4" intake this morning and it says if your running a maf with the 4" intake it will not fit!! Is anyone running a fp intake pipe with a holset and a 2g maf? If not what are you guys using? Any input would be appreciated!! Cant wait to get this finished should have the FMIC installed tomorrow and last thing is the intake pipe.

Because the 1G MAS can won't mate up to the comparably enormous 4" pipe.. and why would you use a 1G MAS in front of a 4" turbo?

If you are running an HTA71.. you don't want/need a 4" intake pipe. Big filter sure, but the FP pipe or equivalent is not doing you any favors with such a small turbo and only 84mm compressor cover..

Man everybody has an opinion on how I'm wrong. Im asking a simple question about how long of a filter will work. I have 3 posts but have owned dsms for 12 years built motors my self and run High 11s on a small 16g. I'm not using a 1g maf I'm using a Hacked 2g maf. I'm retaining a very stock set-up ala 2g maf and bov recurc which is why I'm using the 4' fp intake. 84mm is about 3 1/3 inches. Nobody makes a 84mm intake pipe with recurc for a Dsm, my only other option is dejon intake but it's ugly and over priced. Im a self builder/tuner and don't want to deal with the sd headaches for now or the local tuning experts who have no clue what they are doing. I like to keep stuff simple

Everybody who is helping with my question thank uou

It's not really an opinion.. having had a 1G sensor/can assembly and the FP intake on hand at the same time.. its a fact they won't work.

You've been building and tuning these cars for 12 years.. and you are hung up on a filter question, as well as why FP states the 1G MAS won't work with their 4" pipe?

I am a self builder and tuner as well, not really sure what that comment has to do with anything.. I've used 1G, 2G and Evo 8 units, as well as speed density.. why are you using a 2G MAS with a 71HTA?

If you are a self builder.. why not make yourself a proper recirc pipe? And for the money you are spending on a turbo, why wouldn't you pony up and get a proper tuning solution.

Idk where u get 1g maf from I never said anything about it, fp on thei site says u cannot use a 2g maf with a filter in a 1g car because of clearance issues. I'm not gonna bicker you guys enjoy your 500-700 hp cars I'll enjoy my slow car. I don't have access to fab stuff and it's not simple to fab a piece of metal to an oval shape that fits the 2g maf And put weld in a recurc tube. I'm not broke and don't mind shelling out cash for quality parts I do mind paying local tuners to "tune" my car lock my Ecu and do a shitty job

Reading is hard some times I know

Seems like any filter with a 5 inch element or smaller should work than correct? I wonder why fp says you can't use their 4 inch intake on a 1g with a maf. I'm gonna get the k&n most likely I don't trust these Chinese filters, I have read a few horror stories of them falling apart under big boost and getting sucked into the motor

This is your post, pertinent bit in bold.. do you not even read what you write?

And there's a picture in this thread of a 2G unit in a 1GA on the FP pipe:

I have had an Evo 8 MAS (which is shorter) on the FP intake in my old 1G, so make yourself a plug n play cable Mr. DIY

A muffler shop could do the intake pipe for you on the cheap, btw.

As far as proper tuning, ECMLink for instance is not something that will be locked, and on your mostly stock setup it would be a breeze to learn how to tune.

With a 16G or a 14B with a 2G MAS you couldn't ask for a simpler setup.

heres a shot of my S200sx on SD with the FP pipe and a 9" long filter in my old car

Still tho, why would you cripple your bigger turbo by a restrictive maf. I went from a severely hacked 2g maf to a maft setup and went from 550whp to 650whp, just by the airflow increases.

Totally agreed. Go SD or maf blow through if you have an hx40 in the first place.

When I ran an hx40, I had a similar intake pipe to landspeed's, but cut a hole in right behind the passengers side headlight in the engine bay. This allowed me to place the air filter in the wheel well on the passenger side and worked nicely. I had a K&N filter on it. This is what the pipe looked like:

I couldnt fit a 2g MAF with my FP 4" intake. I wasn't motivated to do it because I wanted to run speed density any way.

4" Intake

Where the old side-mount got air from is now leading straight to my air filter:

Intake 2

Damn!!! Was that in draw-through or blow-through? I assume blow-through, but I hope you say draw-through

I'm sure you did... I will be running a hta71 shooting for about 420whp. I still find it hard to believe u gained 100hp just from switching. I know once u get around 450 even a hacked 2g is a huge restriction but I don't want to go speed density till I get my tune sorted out. I'm very comfortable with maf tuning.

The power was already available, he just let it in and tuned for the new found airflow.

Totally agreed. Go SD or maf blow through if you have an hx40 in the first place.

it was blowthru, I actually didn't even touch the tune. I put a stock mas compensation map back in and plugged in the zeroed out maft. It was dead nuts on. I was on a HY35 so I was at the very end of the map. Now we all know that a turbo's flow is volume limited, not mass. So if you make the air going in less dense the mass flow will fall off. Well I had over 1.5 psi drop on the 2g maf. Thats like a 10% loss in flow, plus the other losses from making the compressor work harder.....


On the HTA you'll probably be ok at that level with a stock 2g maf, but anything more and you'll wanna upgrade.
