i have a 1992 prelude si 4ws with an h23 that has blow at 234k i am looking to swap out the h23 with a jdm f22b dohc and i want to turbo it on a budget i read alot about people using dsm manifolds and turbos but i don't know which turbo i would use do you guys think and evo 16g would be good and how much power would i make at like 9 psi on a stock block and head with dsm 450cc injectors.
also would this be good for a DD i am trying to make like 250whp and like 220tq and can i just get a ecu made for my setup or do i have to get it tuned

I think a 16G would do it, and you will definitely have to tune your car.

 

how much is a tune usually. (how many hours does it usually take and what is the best program for the price)

 

any body know

 

https://honda-tech.com/zerothread/902309

or google search tuners in your area

find a shop near you and check their website for prices, or give em a call

 

no one can tell you how much power you will make. That argument is vague and ambiguous.

regardless, a turbo setup needs to be tuned.

 

Real. True. Tunning.

 

Forget f22, H22 that! Then it'll be a 1992 Honda Prelude SI 4WS VTEC

But yea the power you make is mostly in the tune you get. Especially with DSM setups. Also, check out Forced Induction section

 

what else would i need to turbo my car this is what i know i need so far????
turbo
manifold
bov
ic
ic piping

also how do i hook up a boost gauge??

Look at the FAQs in the forced induction forum. If me or someone else just gives you a list it's not going to help you learn what's going on in there.

 

didn't find anything

Go to the forced induction forum. Then look at the top of the page and click on the link that says "FAQS". Look at the threads inside and there is more information than you could ever read.

 

Adam, nobody here is going to spoon feed you. Start reading EVERYthing you can get your eyes on. And don't say you didn't find anything, everybody here knows you read for 5 minutes and gave up because it wasn't spelled completely out for you. Information is hard to sift through. You have to do alot of reading as a result. Don't be scared to read. It might seem like a waste of time, but you NEED to understand it, or nothing is going to go right with your build.

They aren't trying to be jerks either. They just don't want you getting into something you don't have a clue about (which is a very dangerous scenario)

You need atleast a month solid of reading and researching before you even think about buying your first parts.

I've done a DSM setup. Heres my list. I used a 14B due to its price. Your good with 16G as parts are more available but a touch pricy in my opinion.
You need injectors, exhaust turbo manifold, waste gate, blow off valve, maybe a fuel pump (yours is pretty old, so might be a good idea to swap out if you have the available funds), your only looking for 250 though so you might not even need a fuel pump or FPR. You'll want an intercooler, with piping. You'll need oil or water lines to cool your turbo. You'll need your turbo compressor/ turbine housing. You'll need a down pipe. You will probably want a full exhaust system too. A restrictive exhaust is no good in a forced induction system. Also, Tuning is a must. If your really low budget, go with crome (my personal suggestion). Its a bit buggy, but the bugs can be worked around, and crome is very user friendly. You'll need at minimum a burn1 unit(chip burner) with usb cable and some 27sf512 chips ontop of that. Or option B is to find a local tuner in your area, but that is going to be pricy. I've found it was more cost effective to tune myself (get a basemap up and running) and than have a tuner tweek your maps and get you at the maximum performance that is still safe. I probably save close to 400-500 dollers going this route, and than you learn how to tune yourself (which isn't hard at all with all the support in pgmfi, xenocron, moates. Search these last three companies/websites too. They have lots of good information aswell.

good luck!

The dsm setup I have is still under 1000 dollers and after final tuning should push 240 hp - 250 hp off the 14B I have. Be patient too, you can come accross a good deal if you wait for it. I got my 14B for under 140 dollers (after replacing some parts). My injectors I'm still deciding on but have been made aware that I could get away with vtec injectors. I'm unsure of the fitment of them in the h23 but I can find that out very easily. Trough tuning I've found If I keep it below 4-5 Psi and don't go to 7900 RPM I won't max out my stock injector duty cyle which is good for approx. 30 hp in my situation. I personally have it tuned to have its best performance between 2000-4500 (which is based on my 14B turbo, it spools up fast but can't maintain high boost at high RPM's because of the displacement of our motors, but your 16G will have no problem at all in higher rpm).

Last thing you need to pick too is if you want it as a track, drag, or Daily driver. This will determine when/where you want to be making maximum power in your power band, and that will help you utilize it for what ever application you decide.

Hopefully the list I made will get expanded for you. I'm sure I've missed alot but I want to get accross the more crucial things

 

thanks for the help
