ok - i have a 90 crx hf - i wanna boost it but i have no money what im looking to do is the basic junkyard boost setup! i heard the hf mani works, but i dont know what turbo. as far as intercooler i will probably be running a dsm side mount. also heard dsm injectors work, not sure though. i will most likely convert to obd1 with uberdata or maybe try chrome for engine mgmt. so basicaly what im looking for is a complete parts list for junk yard boost setup - any help is greatly appreciated - thanks!

Popular turbos are. 14b t25, from dsm,s, and t3 from volvos.
Dsm injectors work fine , u prob neeed a resistor box .

Check out

homemadeturbo.com,
they have builds like your looking for.

thanks for the info

14b is bigger than the t25 and flows more. 450s dsm injectors are ideal on a budget. Walbro 255 pump is definately needed. No resster box is needed cause a hf is multi port. And if you are goin to boost the hf scrap that idea.

Because of the toothpicks that hold the pistons to the crank.

D15's can take a good 160-170whp before they become 'unsafe'. As long as the motor is in good shape, you tune it correctly, and don't boost too much, it should be fine. I'd pick up DSM 450's (Hf/Si/Ex already has the resistor box), the sidemount, and the 14b turbo, slap it together - and have fun. That's what I plan on doing with my next beater - see just how cheap I can do it.

HF motors have only 8 valves and are the weakest d out there
get a d16a6 ant turbo that

Ditch the stock HF engine, get some flavor of D16 for teh win.

T25 too small, Volvo T3 turbine housing has the fucked recessed circle that makes it impossible to get a seal against a proper T3 flange, and 14B is barely big enough.

I recommend a straight T3, hands down. The smaller ones aren't much more powerful than the 14B, but they push less charge temps at the same power level. They run about as much as a 14B in the same condition, too.

Yes.

14b's are making 200+ on SOHC's - too small?? It's not like it'll be a high-rpm vtec screamer - it has half the valves.


BTW - once machined, the volvo t3's (92+) are excellent housings. VERY strong/hard 4340 steel (as per friend, had to use his carbide machining bits), not going to crack anytime soon. After I got the recessed circle machined out & WG flattened, it's perfect.

That's some mighty fine sig material, right there.

Does anyone have a picture of this recessed circle?

nickromeo

i had that **** happen to me with the volvo turbo. i paid 50 bucks to machine it flat before i actually started doing my preapprentice.

i dont have a pic of what it looks like before machining but here it is after




just imagine a circle all the way around the inlet part thats about 1/8th of an inch and when u bolt it to a standard flange on a manifold it prevents the whole areas to sit flush and the who damn this is a nasty leak.

Hrm. Good job of making a part I'd normally throw away into something usable for $5-15 dollars. Sure saves you from the hassle of sourcing a different exhaust housing!

srt41320

ok well i cant seem to find a d16 around me but i do have a d15 16 valve i can get for free - but how much will the hf motor handle (with a good tune and about 5-7psi) before i blow it? how much would the 16 valve handle in the same situation? im tired of boosting vtecs - want to do something challenging for once i guess

Come on now joey, play nice.

The 14B is a fine turbo for a non-vtak single cam. I know from experience on that one, you probably do to.

But also I just tuned a 14B turbo on an LS, and that thing was rather impressive for the setup, and it didn't really die out on the top end, although I wouldn't run one on my car, the 14Bs aren't going to be out flowed on a low revving honda motor.

Joseph Davis

Sorry, I like D16's, and 225-250 whp in an HF is a decent way to cut your teeth.

1st things first! You need money, turbo's are nothing but a bottomless money pit, have $$$ READY!

Joseph Davis

Hrm, look, it's someone else I've been needlessly rude to recently.

Seriously, here's my $0.02 broken down real simple. Keep in mind I'm a rabid HF owner.

1) 58 crank hp D15B6 is not real exciting boosted. I don't have to do it to know it, the sub-1" diameter intake ports tell all.

2) I picked up a wrecked 91 LS for $500 back in the day... add $150 for mount kit generica... this is cheaper than you'll be able to summon together a humble turbo kit. An LS swap is instant double whp double wtq for an HF. With zero loss of reliability.

3) D16 will be cheaper than LS if you shop around, and capable of handling whatever you throw at it by way of cheap turbocharger.

So, yeah, what do you want? A lot of work, car becomes a maintainence *****? Or spend a couple hundred more and have something, even if it is a turbocharged maintainance *****?

anyone else have any pics of the actual recessed circle?
