A dsm h23../
Ok well first of all hi my names mike, this is my first post but ive red tons of stuff on here before. I own a 93 prelude si. I bough it last year w/ 63k , its got 74k now. Its in good shape with a clean body. I hace debated for a long time as to whether buying a better car w hen i got older or turboing this would be a better choice. Because I've put lots into maintenance, and I've grown to like the car more and more, I think I want to turbo it. I've done plenty of research in recent weeks, and I think a dsm setup would be a good first project.
Because this car is my daily driver, I dont much care about peak hp/performance at 5500 rpm. I want something fast spooling giving me good performance with low/mid range power. Im looking for between 200-240 wftlb/whp.It's a daily driver with an inexperienced owner so I think you guys might agree it would be intelligent to get a small turbo and run small boost. I would like to minimize unhealthy strain on the motor. I am looking to spend 2000~.
I've been hearing dsm mani's bolt up so it seems like a good idea. Ic choices are strange, there isnt much ratings to go by for comparing brands. Ive heard spearco, megan, vibrant, or even ebay ic's work well(any testimonials out there?). A 1st gen bov could work i guess or maybe a greddy type s, sounds cool but im not sure if it would stay cool after hearing it a couple of weeks.
My main debate is turbo size. I've read here a 14b is too small. What about a t28 or an evoIII 16g? Keep in mind my application, i dont care if it maxes out at 5k. Also, for a small turbo, what exhaust piping size should i use? I had my heart set on the rsr catback bfore considering turbo(2.3"), but is that too small? Ive been told by some to get a small t3 with a small a/r and trim wheel size. also not sure about injectors.. new or used? dsm, do they fit? 440,450. or 550cc? I would imagine this would require a fuel pump/regulator. I havent considered engine management i know a good, reliable tuner and will request his assisstance both with software and with some installation.
ps. would i have to get rid of the front motor-mount?
Ive done lots of research, please dont direct me to the search button. Ive asked lots of questions and would appreciate patience because i am not a mechanical genious and that's why I want a modest turbo set-up.
thats about it. btw, cut my hand at work its in a cast, so i typed all of this with my right hand only, if that displays any degree of enthusiasm.
thanks, mike.
EDIT:
moderators think I should have placed this in forced induction? not sure.. I guess move it if possible. Also it was a t28 not a 25.

Re: A dsm h23../
yes, the dsm mani's will bolt up to the h23 head with some redrilling of the flange holes.
t25 is even smaller than a 14b.
imo, a 14b is still too small, but it will do fine. but I'd much rather go with a big 16g. It's pretty much perfect for what you want.
get any IC you can get your hands on, as long as its a front mount. You could use a sidemount, but with that small turbo, i'd much rather get a front mount.
you would have to get rid of the front motor mount with a dsm setup. it's not neccessary, many people run without it. you can fab up your own if you're really worried about it.
use 450cc injectors from a turbo dsm.
as far as engine management goes, read up. there are maps out there for your setup, or close to your setup in crome and uberdata.

Re: A dsm h23../
I'm sorry I meant t28! How would this compare to a 16? I heard they were close. And again, I have to fix what I said. My friend told me about the t28 he had, but i think its oe off a 2nd gen eclipse. Making it a t25. comparisons for both would be nice.

t28 would probobly do what it sounds like you want. if you arent gonna hit redline everyday then it will spool fast and have nice response.
get a p28 ecu and im sure you can find a base map that matches your setup pretty close for uberdata or crome

Re: A dsm h23../
sorry changed a few things for that post in fi but o well....
can someone please tell me if i got a evoIII 16g and wanted to lower the wastegate boost setting how could i do it? would I need to do an ext. wastegate? Can the wastegate actuator arm just be lengthened?
please help me out, i want this turbo the most but i need to figure out how to limit the boost.
mike.

if you are a little handy with some metal, you can use a wastegate actuator that opens at a lower boost and make a bracket to make it work
