2g intake maifold - swapping soon to 1g

BKs50trimGST · 05-03-2005

Once my new turbo is in and i have some money to get my 1g intake manifold installed i was just wondering what kind of stuff has to be done - i have a 1g intake manifold and i have the 1g throttle body but for my turbo - THE 50 TRIM do u think i should get my 1g intake mani ported or anything ported or just leave it as is - i got my 1g intake manifold along with a 7bolt head and a crankwalked 1g block from CRACKA awhile ago for real cheap. If anyone out there has a 1g intake manifold already ported or something reply to this or email me, i'm open for all your idea's member i know some stuff about dsm's but i'm basically a newbie to half this shit you guy's are talking about. newbie in need - SOS

Its spelled with a K not a C

If you have $$$ rolling out of your ass, I'd get the intake manifold extrude honed and have the head ported either by Mike at QPR or by FFWD Connection. Both will help, neither are necessary.

You state that you have a 1g head. To make the the 1g intake mani even be worthwhile you'd have to port the opening of the 2g head to match that of the intake. The 1g intake ports are much bigger than the 2g openings. Your airflow is gonna hit a lip of deal wall and create weird turbulence. I did all kinds of reading/posting on this. I read just as much good as i did bad. Someone else here can probably tell you more. You'd probably be better off with a 1g head/intake combo unless your port the head. I was in the same boat you are. I have a 1g intake that i was gonna put on too. Too much reading caused me to just fork out the $650 for a Magnus. I'm also putting a 50trim on too. My car isn't running yet, probably 2 weeks out yet. But to answer question, of whether to get the intake mani ported, i probably wouldn't waste the time if you're not gonna do anything to the head. You will only be able to reach in so far with porting tools anyway. You will have to get it extrude honed if you want it ported thoroughly. That's pretty expensive.

Good Luck!

Well i got 2 opinions on this, OneFast99GSX said that i have to get 1g head and Kracka says all i have to do is put it in, i think - porting and honed but i don't need it - so i'm confused on this, i talked to shindley and he says it's just a swap with alot of welding 2g parts to the 1g intake manifold and stuff - so right now i need to know this: do i need a 1g head for the 1g intake manifold - i have two opinions and just wondering which one is the right one - i know i bought the intake manifold from Kracka - but i think it's a 7 bolt head - i know it's off a 1g so should i just use that? the head is in good condition- all i need is cams and im just going to get the hks 272's and be done with that.

**Kracka** · 05-03-2005

YES, USE THE 1G HEAD WITH THE 1G INTAKE MANIFOLD AND 1G THROTTLE BODY. Bring the stuff out to Shindley and he'll get it taken care of for you.

Onefast99gsx · 05-03-2005

You don't absolutely need the 1g head for the manifold swap. I hope someone else chimes in here. Scroll way down to the bottom of this link and read/compare. When your guy says welding, he must be referring to the map sensor mount that's located on the 2g intakes. I'm confused on your one sentence where you think it's 7 bolt head and off a 1g. I don't know if 7bolt heads came on 1g's. That question is more for a pro on here. If you find out you have a 1g head, yeah put the intake on but if it's the smaller port 2g head I guess find out from someone on here if it's actually worth it if you don't port the 2g to match the 1g mani. Nothing seems to be a direct swap to me anymore. 1 upgrade seems to lead to 3 to 5 other upgrades. For example: I think the 2g coil pack mount is different than a 1g, so that's another thing you have to do. By the way- I went with the 272 cams. I did about a months research on cams especially the Forced Perf. FP2 cams. Sent numerous emails to FP and never got one in return(a return customer too), so i said fuck them and went to the HKS 272's. Probably the best move i did anyway.

92.5-94's had a 7 bolt head. It is very similar to a 6 bolt head, but is supposed to offer a bit better cooling. You won't need much porting on the intake manifold. A bit by the throttle body is all that is really needed.

Onefast99gsx · 05-03-2005

Thanks JET for clearing that up for me. I didn't want to give him bad info.

**Kracka** · 05-03-2005

The 1G 7-bolt heads flow slightly more air and have larger oil and coolant passages.

Onefast99gsx · 05-03-2005

Yes, that's what i thought too about the 1g. The 2g's have a better port angle and better in the long run 'when' professionally ported. At least that's what i gathered from a senior member on here.

BKs50trimGST · 05-03-2005

ok awesome - thanks for the help kracka and onefast99GSX, any more help on this issue would be helpful

BKs50trimGST · 05-03-2005

one more thing - how much ponies am i looking to gain when i do this swap? anyone who knows i would love to hear from yah

The 2g coil won't bolt onto the 1g intake manifold. You would either need to use a 1g coil or you can just mount the coil somewhere else. That is not a big deal though.

You can use a 1g intake manifold on a 2g or 1g head. If you have a 1g head, it will flow a little better but either will work for the 1g intake mainfold. I don't think you should worry about porting the intake manifold since it won't make much of a difference. I didn't bother with mine.

BTW, BKs50trimGST, I want to race you in my gst when both cars are running. You talked to my brother a few days ago about your turbo. I have the black awd talon that raced you last year.

BKs50trimGST · 05-03-2005

and i remember, i got smoked and so did my buddies srt-4, btw - my car won't be as fast as your awd but it will be interesting to see against your gst, off the line and on the roll. just gimme a week or two to get my skills in driving back - havent driven this car hard in about 6 months - my car will be done on friday! ordered my 50 trim from elite auto sports - AWEsome place also - charged me 950 for the 50trim brand new internally gated with the stage 3 wheel and didn't have the stupid thing hoaged out like my other one did - so now my o2 housing i can use - my dumptube will be of use - amazing! and i had it shipped overnight to shindley. major props to elite!

BKs50trimGST · 05-03-2005

shindley told me when the time comes he knows what to do with the coil pack from the 2g, he explained it to me but i wasn't listeneing - to much information for such a small mind that i posess - how the hell do u spell that word, w/e

Jakey · 05-03-2005

Oh boy, I can't wait, more stupid f*cking street racing. I better drive up to the Cities so I can watch.

slowbubblecar · 05-03-2005

I got the gst on the 3rd of Jan, drove it for a month and it hasn't been running since besides 1 pull with the 20g. My car should be running soon. Few little things to work out before starting.

Come on Jakey, there is no need for this. Most of us on this board street race, it can't and won't ever be stopped. I suppose this is just a fact of life you'll have to come to accept. You can't tell me that you'll never go WOT on the streets with your Laser once you start driving it.

It is easy. If you are putting the 1g 7 bolt head on, you would want to get arp's, a new hg and timing parts. I wasn't sure if you are putting it on though.

Onefast99gsx · 05-03-2005

You might not even have to dick with the Map sensor either. When you get like a aftermarket SMIM, some people i understand have it connected to the wire but just dangling or zip tied someone and not even attached to the manifold.
