I got a crx for $150 bucks. It is an 1989 crx hf with an 8 valve 1.5 liter motor. Compression check in each cylinder was over 190. Compression is 9.6:1. My question is I am boosting it. Bought a junk yard turbo for $100 and an intercooler from a mazda mx6 turbo for $50. The hf manifold mounts perfect to the kkk turbo, I believe from an Audi. I want to Know will the stock honda clutch hold 5-7 psi. The goal is to keep the project under $500 dollars. Totally cheappo. I already have a fast car. Now I just want to be able to pass cars, the hf has no *****. However a little boost will wake it up a little. This is a daily driver and I am not looking for power. I need to know because the clutch is stock $75 new. Again, what can the stock clutch hold. Could not find it in search.

kind of a waste of time trying to turbocharge a 70hp motor

KC GSR

I actually give the guy props...I would turbocharge my lawnmower if I had the resources to do it

Speed PHreak

Well,, you could prolly do it. I'm not sure what you're gonna do about fuel management. Zdyne would be one way, but that would put you way over your budget. With the HF's 5500 RPM redline you won't really have to worry about top-end, so a junkyard t3 or mistu turbo ought to work really well. You've already got the HF manifold that fairly easy to adapt a turbo onto. Fab you up a downpipe and some charge piping and you ought to be set....You've already got the I/C so get on it dude!

I think it would be pretty damn cool if you could do it and have it be reliable. Heh turbo HF, that's crazy dude

I got an 88 hf I was thinking of doing that to. haven't decided what to do about fuel management yet, as I hate to kill the gas mileage, since thats the whole reason I bought it. I have the wagon for speed. any ideas?

333

The question wasn't whether it was a waste of time, the question was about holding power and the stock clutch. I didn't want my question to be answered with a question, thank you. To me its not a waste of time. I am bored stiff with my street car. So all my left overs from the street car are going on the HF. Totally cheap and free stuff. Calling in all favors, trying to be the ultimate sleeper. Nothing special.

Well you may need some different rods, most d-series rods are like pencils. I'm positive the HF's are even worse, everything on the HF is tiny. I think ZC rods are good for about 225whp, i'm not sure about fitment tho. As long as you kept the boost really conservative say 5~6psi max. It'll be a sleeper from hell. Just remember the HF exhaust is about this "o" big.

333

It came with a cherry bomb and no cat and an si intake manifold and throttle body with a si exhaust manifold. I want to run only 5 psi nothing more.

falcongsr

thats a cool project. i bet the mileage will stay high if you dont boost all over. i would question whether the rods will hold up. plus the cost of a FMU, wastegate, intercooler, piping, oil lines etc will add up. i made the mistake of buying a turbo first and then realizing i couldnt meet my budget adding all the extra parts to make it work. good luck.

MiraiZ

just to let you know...the HF clutch is very small so it won't stand too much abuse...I don't know if they ake aftermakets for the HF either

mos

I think the stock clutch could be alright if you are careful with how you treat it. It's not like its going to have to handle 150 foot pounds or anything.

How much money does one spend on fuel management for a $150 vehicle with a $100 turbo kit?

333

fuel upgrades, check valve 240cc injectors and warlboro 255lph fuel pump which I recieved as a gift from a friend. Raise the pressure to about 70psi at idle with my fuel pressure regulator and here we go.

foesicks

Gonna blow that **** up, I hear people saying to run a few pounds of boost just turn the idel pressure up to like 70 or 80 and go for it. Well this guy I know blew up 3 sohc putting a turbo on with no kinda fuel managment, well the 4th motor came around so he decided to just crank up the fuel pressure to the max.......well it didint work for less than 15 min.

333

I ran 10 psi on my b16a with no fuel management. Just raised fuel pressure and injectors. Looked at the a/r ratio meter. that's it. Blew the motor only when the wastegate rod clip fell off and the boost went to 20 psi on 10.2:1 comp. Blew the ringlands. I had plenty of experience with this. My friend is a tuner, he has the wideband 02 sensor. As long as were 12.7 or lower on the a/r motec meter we will be fine. I don't care about of gas mileage and I don't care if I blow it up. I only paid $150 for the car. I have a walboro 255lph fuel pump. It will be fine for 5-8 psi on a 9.6:1 motor even if it is not tuned right. My friend put a home made turbo on his vw vr6, un 8 psi. Only has big injectors and a homemade mass airflow sensor. Run fine. He tuned it with the wide band. Sometimes people just put to much emphasist n fuel management systems. It just confuses most of the people out there. It can be done, and it will be done. Maybe by the end of the month. Just installed a clutch for $75. I'm in the process of mounting the intercooler, cut a hole in the hood or put it in front of the radiator.

STOCK CRX HF Horsepower is only 52HP

EKB18BPR3

KKK audi turbo WILL NOT mount to hf manifold. i know for a FACT because i did a junk yard turbo. if u look at my avatar u can see the KKK audi turbo mounted to a plate which in return mounts to a hf/vx manifold. so u will need to fabricate a plate to fit between turbo and mani. and just letting u know even a junk yard turbo will cost u over a grand for everything. because u cant find EVERYTHING at the junkyard so u gotta buy **** on ebay and here on HT. wont be cheap but good luck. PM me if u have any questions

crxhybrid1320

I've seen alot of junkyard setups and ill say you get what you pay for
just get the greedy kit with a conquest intercooler and you will be set!
If you dont spend alot you dont get **** but a busted setup!
My opion good luck i guess!

Blaze45

Correction stock HP for the 88-91 HF CRX's is 62hp. If you slap a Si or Dx head on there you'll notice a difference in power.

Sounds fun Good Luck

Stock injectors and raised fuel pressure on a B16a with 10psi, either you are XXXtremely lucky or your pulling our legs..... I can't imagine what kind of fuel pressure it would take but how was the idle or low rpm driving since your not controlling fuel increase to come in with boost as it should, its smells wrong to me.

Your clutch will be fine as long as you don't go drag racing the car...

Speed PHreak

DX and Si head are 16v, the HF is an 8v engine.........won't work unless you swap out the pistons to 16v pistons.

Joseph Davis

LIES. There is no way that will work.

You CEL on boost when the stock ECU sees over 3 volts from the MAP, and the car starts running in limp mode until out of boost. Can you say ka-boom?.

Blaze45

my bad about the SI DX head... I though I read somewhere that you could just swap em out....

sorry

Blaze

reXem

I ran with my ZC with only a fuel pressure regualtor bumped it to about 40psi at idle, no check valves or anything getting CEL everytime I hit boost. I ran 14.7 @ 96mph at high elevation and a screaming hot day. Never had any signs of detenation. Head Gasket blew but hey it was a 12 yr old gasket oh yeah it was 6.5psi...

crxhybrid1320

sorry about the 10 hp off its still weak!

My friend works at Ti automotive, he is making the plate so the kkk can mount up to the manifold. INtake will be on the left side, The junk yard intercooler mounts in front of the radiator. I am calling in all favors. My other freind works at a muffler shop to bend piping if I need it.
I WILL BE USING A CHECH VALVE. I don't care about gas mileage and I don't care IF I blow the motor. My friend is a hondata tuner. WE have the wideband o2. As long as we smell the gas and get the a/r fuel to 12-11 we will be fine. The kkk turbo might be a little bit to big for the 4500rpm motor. I also forgot to mention My freind downloaded hack software for the SI ECU. Here is the set up: kkk turbo w/ plate mounted to hf manifold, 240 cc injectors, check valve from my first completed project, FPR set to 50, mazda mx6 intercooler, have an SI ECU from my first car, Had an INtake manifold from my first car, Have an exhaust manifold from my first car, I'm doing the work all by myself at my job so I don't have to pay anybody else.
