so as of now my car is on a fp 18g with a built bottom end, hks 272 cams, supertech dual valve springs and retainers, 3 inch exhaust front mount, and the basic bolt ons, spiking 30psi falling to around 27-28 area, using rc1000cc injectors and a wally 255 pump. i have link 2.f and maft as well

I plan on getting a few more things and then hitting the dyno. there really isn't much info out there, but i would like to take a stab at "bastard dsm's" record for the 18g.... i have tried to contact him several times with no reply. my car feels like it is no where near his 455whp mark that he set and i was wondering what direction to go to help my chances. thanks for the advice in advance

Have you tried putting on some nice reflective stickers? I heard that can help a lot.







Just in case you weren't sure, this is my attempt at a new concept that I have learned about called "humor".

Does anyone have any usefull information. For me?

You're heading the right direction but it seems like right now it would all depend on your tune and maxing out that turbo which I imagine you are doing at 30psi.

I'm not 100% on 18G turbos and their flow but if there is still some stock equipment you are on (intake manifold, exhaust manifold or anything flow related) you might want to do some research in that area.

Yes newbie, that will help you get out of probationary status dumbass. Try a new form of humor you one-of-a-kind comedian. This site is about having a community of tuners that help and support each other with knowledgeable and informed responses. Keep it up and you might want to look into some kind of Honda forum.


As for the OP, I would try to get into contact with the rep from FP on here:
PM this guy: Michael@FP
The FP 18g will definitely put out more than an EIII 16g for sure.
Hope this helps

OH, and you could try the waybackmachine website to find FP's old spec sheet when they used to sell it on their website (forcedperformance.com)

Thanks for the advice on getting in contact with fp!


I plan on getting a smim before the dyno. I wonder I'd Benifit more by upgrading to v3 instead? I wonder if a "race" version smim would be the best choice with this small of a turbo?

Also check out "bastard Dsm" he is the most hp 18g on here, his mod list and no nitrous don't seem to add up to his hp # to me can some one maybe shed some light on this for me ? Anyone else out there ever get dyno numbers with an 18g turbo ?

This guy put down 387 on 23 psi with pump gas.



Sorry, I think its fixed now.

page not found.

I ran a FP18g6SL2 for over a year. I finally killed after a couple months of running it at 30 psi. IMO its really more of a 26-28 psi turbo max!

I managed about 42-44lb/min IIRC. I ran 11.9 @ 115.

I recently switched to a SMIM, which made a world of difference from 7k+ but I am running an HX-35 which holds boost up top.

V3 probably won't help you as much as a SMIM, since you already have DSMLink. The turbo will still run out of steam up top though...

No dyno ?

SMIM with the N/T TB, and a external WG setup to make it hold 33-35psi if possible is the only way to get a nice jump from were you're at .

From there its too expensive to try and maximize your turbo, to get every little last drop bigger cams etc which is a waste since you have HKS272s already.

Thanks vinny. I'm most likely gonna get the smim then start looking to upgrade to a bigger turbo setup.

Wow, sorry if I pissed you off tough guy. Wasn't looking into insulting anybody when typing up that remark. AND....which this probably doesn't matter to you, I don't care for Hondas too much. Without further incident and saying something that may get me in trouble.........I apologize

i have the greddy 18g and many people have told me ill go to the 400s with the right setup and tune.

I don't think anyone likes Hondurs . Just help people out instead of just trolling threads. And apology accepted. (It was a late night and I was tired, sorry if I got a little in your face) And easy with the "tough guy" remarks there aye?

Least you realized "now you ####ed up" . (to much whitest kids you know...)

Good luck on your goal.
I am running a blouch racing 18g with a evo3 exh housing and dump. I just installed it not too long ago. So I am working on perfecting the setup.

Let me know how you make out, and what info you are able to gather up.

You could install a meth kit to try and squeeze out all the power you can out of that 18g. You'll be able to have a more aggressive tune witch should crank out a few more hp numbers! You could also add adjustable cam gears so you can degree the cams in for max output... Just a thought, good luck you are deff on the right track tho

I am running an MHI 18g with a 7cm hotside, and it is definently a nice turbo. I haven't been able to pull anywhere close to as much power as I know it is capable of yet. I still have the stock exhaust manifold (that recently cracked), and am still running on my 2.5" intake piping from the 14b I had previously. Still, even with those problems and only a basic knowledge of what I am doing with ECU Flash, it's putting around 300 hp to the ground, based on calculation. I would think that just opening up the exhaust with a better manifold and going up to 3" intake piping should net a big increase...

based on the stupid link calculations the car is making right around 400 hp right now. i just wanted to know how "bastard dsm" made so much and what little differences his setup has.


all and all there is very little solid info on the 18g out there compared to every other "dsm turbo". but I am very happy with how the car feels and pulls. i managed a 12.4 @ 114mph in the 1/4 with a 1-2 shift you coulda made a sandwich waiting for.

I believe the main reason you are having trouble finding info on the 18g is, its not that popular. What I have gathered, the 18g spools like a 20g with the kick of the 16g. Meaning, if you can stand the spool, go to the 20 and have more flow. If you like the flow, go to the 16 and have better spool.

well acording to the dyno challenge on here the 18g makes more power than a 20g.

I will give you that, but the dyno challenge also supports my observation about the popularity. 5 18g's to 12 20g's. The 20g is the tried and true big turbo of DSM platform. Buschur, Shepherd, all the big boys used 20g turbos back in the day. BTW, only one of the 18g's is making more than the top 20g.

This is what I was talking about... This train of thought is totally backwards and completely wrong. I can tell you from experience that the 18g spools almost identically to a 16g. The difference isn't even noticeable when driving. It does pull noticeably harder than a 16g once it is spooled though. It isn't much less than how a 20g feels. If you go look at the compressor wheel measurements between all three, you will find that the difference is extremely small, step wise. If I had to describe my 18g, I would say it is much more like a 16g with the kick of a 20g. My 18g is an MHI turbo with a normal MHI 7cm turbine housing though, so it is probably different than the Greddy 18g.

i'm not dissagreeing with anything you're saying. the unpopularity of the 18g and lack of dyno sheets out there are the reason I made this thread. to see if there is anyone out there with some first hand experience with this turbo and supporting mods for it.

My personal opinion, because compressor and turbine side are close to the 20g, supporting mods for the 18g would be quite similar to the requirements of the 20g. Maybe even a little much.
