This topic is also in the FI and Prelude sections.

Hello fellow H-T members. Well, I am about to buy a T25 turbo DSM set-up. And I would like to get more information about turboing a car. Yes don't worry, I've been reading up and searching here and all over the web about turbo information. Asking people, ect. Its been about two years now and I have been waiting to turbo my already slow Prelude SOHC NON-VTEC F22a1.
The person that I am buying the kit from is also a fellow H-T member. The DSM kit is bassically complete. Here is the list of things that I'm going to buy from him.

Turbo XS dual stage boost controller
Chipped p06
DSM manifold re-drilled to fit f22a1 with t25 turbo
DSM 450cc injectors
Custom 2.5" turbo downpipe
Stealthmode oil lines
Tapped f22 oil pan

He was also selling SMIC but I told him that I am going to buy a FMIC. I know that I need to buy a few more items like OBD2 => OBD1 converson harness (1996 Prelude ) I am going to run a Hondata s300, FMIC, BOV.

My question is, what else do I need for this set up? I know the T25 is small but hey it works! I am looking for atleast 210-220 WHP, with this set up, with stock internals, can I reach that goal? Yes no? Can anyone point me into the right derection into reaching my goal? thanks!


*****UPDATE:
I've done a bit more reading on the T25 turbo. It does seem to be a bit small, but I read that it doesnt hold boost up to the higher RPM. But I think it might be an alright set up for my car, (6200 red line). Like I said, I not looking for massive whp.

I'm not soooooo familiar with turbos, since I don't have one... but from what I've read and seen, your numbers are far too high than what you expect to get from using stock internals.

 

my friend has one on his civic. the highest hes taken it is 15psi but i dont know if thats maxed or not. the advantage would be the spool time.

 

ummm yeah man i would dicourage the use of a t25.. but its up to you... you can get a cheap *** t3 turbo and it should work out better.. thats what i run on my setup and most people even say that a t3 is way to small.. but i like the quick spool time and its fun to drive so whatever... but an f22 with a t25 a hole different ball game then a b/d series engine with the same setup...
* i would just try posting in th FI section or maybe a quick search for more info?*

 

A T25 is a bit on the small side for the majority of people out there, but you should be able to reach at least the lower side of your power goals (240ish whp). I think the T25 would run out of breath before 280 whp.

For me, a T25 would make for a fun track car. (Think of the twisty kind, not straight line.)

The very first line of his post says he has this posted in the FI and Prelude forums as well.

As I mentioned already, 280whp is probably out of reach with a T25, but 280whp is also beginning to push the limits of a stock motor. There's been a couple people to push past that on stock motors (with larger turbos), but I feel it's pretty risky.

Oh, and you need to add a fuel pump.

 

yeah I did post this in the force induction form aready, but I just want so ideas from the fellow f22 turbo owners.

 

How the t25 handles on an F22a1, I cannot tell you, but I have had experiance with them in a few Nissan 300zx's and 240sx's. They are very good for spooling quickly, as there is very little turbo lag due to the size. They are also good at running low psi (think 4-6) with no IC setup to around 13-15 psi, where they start to show little to no gain in power. Over all I have been pleased with the cars using them. Also, if I'm not mistaken, some t25's can be drilled out to fit t3 and other t3 hybrids.

wow, thats nice to know. Well, I want to hear from the other f22a turbo owners. I would like to know what they think of this set up. But yeah thanks!

 

go with atleast a 16g

yeah I do want to go with a 16g maybe I can pick up some of the turbo stuff from the guy and then get a 16g put it on and have a good tune!!

 

would the t25 be a good turbo for 1/4 times? or better for a track car?

 

For 1/4 mile, no, it would not be good at all. To me a T25 is just a good, cheap turbo for making your car more fun as a daily driver and the occasional track or autocross visit. If your power goals become larger later on, you're going to end up buying a larger turbo. If you like 1/4 mile runs, you're going to end up buying a larger turbo, too.

ok thanks to h-t for the information. I guess my power goals are not too high anymore, well for the Prelude anyways, yes basically I just want a bit more powerful car, knowing the f22 with bolts on is still slow. yeah maybe I just might pick up this t25 put it on see where I am from there. If I do upgrade, I might go with the 16g.

If I reach 220-230 with the t25 I'll be happy. Then I'll get a new car then thats where I get the bigger turbo

 

any other more informaiton is welcomes negitive or positive.

 

why screw around with a T25 or a 16g? Then when you want to upgrade (and you will) you'll need a whole new manifold. Start with a T3 if you want to stay small, then you can at least expand to a t3/to4 hybrid later down the line without much trouble.

 

t25s spool up too fast

yeah good point, but yeah for this f22, I now want a power goal level of around 220-240ish whp. I think I could possilbly reach that goal with the t25. I have seen a vid of a b18c? (LS motor) with good power. Just around the whp that I need for this car. Later on in the furture, I'll get a car then get bigger turbos and ect.

 

heres and f22a w/ dsm mani and 16g made 270hp and 240tq, stock block, 272 cam, springs and retainer in the head.

https://honda-tech.com/zerothread?id=1795966

but i would personally start of with a t3, if you want cheap look for a ford t-bird t3 at a junkyard. i personally have a t3/to4e

key word: NOW. You will want more. boost is like crack. then you'll have to change your mani and all your piping. but a 250ish whp daily driver with fast spool will be a fun *** car. good luck with it.

thanks for the info guys!
