im currently trying to find a turbo setup for my car thats low on budget but reliable. i found out that the 1g or 2g dsm stock turbos can fit onto the prelude. ill be using the 1g turbo (14b), 1g 450cc injectors, 2g sidemount intercooler, customs charge pipes...etc.. 1g dsm turbo manifold..it fits with slight porting and redrilling the moundings holes...im getting a aem fuel pressure regulator, BOV(any kind) and i need a fuel pump.. i plan on getting a walboro 255 but my friend but i can also get a dsm pump free instead of buying one. does anybody know if i can use a dsm fuel pump in my prelude?....im going to be running 10 psi daily driven....i know the problems with the valves and the ring landing and seals on the h22... but my friend told me it should be no problem as long as i keep it rich to prevent detonation...he as a 500 hp eagle talon tsi...hes blown his motor twice and now its a fully built block capable of taking 1300hp..... does anybody know of that might become a problem? there are a few preludes out there with a dsm setup but they're all in accords with h22 swap..is there more room in an accord engine bay...anyone with experience with dsm turbo prelude?

As far as I know, the port runners of a DSM manifold match the exhaust ports of an H23 head, but not an H22.

You won't be doing anything with those 450 cc injectors without electronic engine management.

You won't find any room for a side mount DSM intercooler in your lude.

There's nothing wrong with H22 valves, ring lands, or seals. Poor planning and bad tuning blow blocks up.

lasthope05

then wat engine management do you think i should get? the port runners on a h23 fit perfectly but it also fits on the h22 with a bit of porting..i matched it and only have to port 2 and 3..as for the intercooler i see pleanty of room around my the passenger fog light assembly if not then i can always cut away...i can put the side mount anywere...its all going to be custom piping...

this sounds like a really ghetto turbo setup. also, there is no room for a sidemounted intercooler, and do you know how tiny 14b turbos are?

Silver Surfer

^that's the point of the setup
it's low cost
designed to boost about 6psi(i say again 10psi might be to much for dd, you should run closer to 6) so you don't have to do any internal work on the h22

there is a write up on 92lude.com
it suggests 10psi on the h23
but you have to be a premium member

it's only $5 for life and you get pdf copies of the helms in full and broken down formats

I'm doing the same thing but on my F22a. Low compression and cast-iron sleeves FTW!

I'm not sure about the H22 but with the F22 you have to grind a motormount off in order for the turbo to even fit. Also you forgot about your oil lines. If I remember correctly, people on here sell oil line kits for an H22 cause someone I know got one from honda-tech.

Just go with a FMIC. I work on a GS-T and my Prelude and I can tell you now more than likely the stock DSM side mount won't fit. As far as boost, 10psi is pushing it. I'd stick maybe with 7 or 8, atleast until you get a really nice tune and maybe some upgraded engine stuff. The 14b is rated up to 16psi but the stock dsm turbo parts are limited to 12psi. If you plan on boosting much larger, then don't even bother with the DSM setup.

Hope this helps.

6 psi on a 14b is nothing

this setup is pointless, it won't be fast and everything will end up breaking

lasthope05

its a pretty decent setup...its not bad if h23 and f22's are using the same setup. im not one of the "oh i have big *** turbo and ill smoke with a smaller turbo then mines"...im just lookin for around 250 to the wheels....nothing big....it is a prelude after all and the weight is just killer...this way by using a 14b it'll spool really quick.......whats the point of getting a bigger turbo if im not even going to be using it in its effeciency range?...thats like running a big turbo on low boost..

i thought the side mount would fit cause it looked like there would be enough room..

i know of a 5th gen with a rev hard running 10 psi stock internals dd...mines wont be as bad since hes using the t3/t4...rite?

lasthope05

you guys thing a cometic copper head gasket would be good? it'll lower my compression a bit..or do you know of any other?.....my uncle has a fully built h22 hes selling so if i blow my motor ill just buy the motor off him..i know you guys are gonna say.."buy it swap it in now"..but theres really no point since its the same motor and mines still run good..

Hawkze_2.3

10psi is too much, man. Don't rush into this like you're doing and do some more research.

darkspector

except that his is fully built. You should also make sure that that turbo is gonna be any use on your motor. I'm sure the prelude has a high flow than a 1g dsm. So wouldn't that significantly lower the efficiency range of that turbo? You might make power through a very small band and then it would drop out quick. But hey.. I could be wrong.

cfran55

so turbo on f22 isnt a good idea??? im thinking about doing this but still researching i want a dsm turbo setup

94preludeguy

Maybe people turbo their F22. The engine itself stock is pretty damn strong and can hold a decent amount of boost. Just got to do research man.

no from wat i know the 1g dsm setup is good initial setup for the h23 and f22...its just a problem for me because i have a h22....

cfran55

yea im not gettin the turbo anytime soon still reading up on it and what ill need

mullet6577

the DSM manifolds don't work (without lots of work) on H22's. Exhaust ports don't line up right.

F22/H23 = 0--0--0--0
H22 = 0--0-0--0

chitownrida

a buddy of mine has h23 with the junkyard dsm setup

put down 220 whp. safc hack/ dsm 450's / walboro 255/ tiny side mount intercooler/ exhaust dump

i dont recommend it, its prolly not going to last long especially with safc hack

the turbo is small so to make that kind of power is like 10+ psi

i think stock dsms can go 14 psi on that turbo.. i could be thinking of the t-25 though

but big psi on those small turbos is just dragons breath

94preludeguy

14b turbo is rated up to 16psi it's just the stock DSM parts that aren't.

No turbo is rated for a particular pressure for all applications.

its not going to be alot of work...just a bit of porting..ive read up on this..and took my header off to match...if i port too much then i can just get the h22 header flange and cut the flange off th dsm manifold and bend ports 2 and 3 and weld back together...its not as complicated as you guys make it seam....

yea..i can kinda see this now..im not worried about the manual labor...me and my friend will be doing most of the work at his shop...i was really just looking for quick spool and power in the lower rpm range thats why i though the 14b would be a decent setup...i'll see after it is installed and tuned...if the 14b does spit out tones of hot air then i guess ill have to up to a 16g....

im not really trying to say anything but people who say it doesnt work obviously hasnt even tried it themselve..they just say it because they hear from others, "it cant be done" so they so they assume it is true...that my friends is ignorance

sharkcohen

Why not just get a cast log manifold made for an H22 and a t3/t4 turbo? Get used parts and it probably won't cost much more than what you are planning. Your real expense is going to be in custom piping and engine management, anyway. What you want to try to do with a DSM manifold just doesn't make any sense.

mullet6577

Myabe I should have phrased my reply differently, not that it CAN'T be done, but with the work involved getting a DSM mani to work on an H22 head it's not worth it (IMO).

sharkcohen

Not worth it at all when you could probably pick up a used Drag manifold for under $100.

Jeremoose

Just to clear a few things up...

With proper supporting mods a 14b turbo can and will stay efficient up to 19-20psi...

Also for whoever said that stock dsm parts are not rated for 16psi, this is false as well.. The only stock part on a dsm that can't hold/support 16psi on a 14b is the fuel pump which is a cheap upgrade.

If you get a 14b you'll be pleased with it because like was said earlier it reaches full boost quickly and holds boost well right to redline.

That being said, the 2g DSM stock T25 is garbage and can't hold boost.
