THIS IS FOR A D16A6 MOTOR IN A 89 CIVIC SI HB.
I know the greddy D series turbo is a 5psi turbo without a boost
controller, but what turbo cars(that came in common cars in the US
specifically nor cal or just california) came with a simular low boost
turbo stock? I am still looking for a turbo to get that is low boost,
possibly a volvo because I heard they boost low.

I just need a turbo that is low boost. What is the psi of a 2nd gen
eclipse turbo and the 1st gen? I think it was like 7psi or 8psi, but I
can't remember.

I already have my HF manifold, some charge piping and an a/f guage. I am
thinking I need:
oil lines and related oil feed and return items
down pipe made (gonna have a muffler shop make one)
450cc injectors off of a 2nd or 1st gen eclypse
VAFC mod or the Zdyne ECU
Fuel pressure guage

I probably will not be getting a Zdyne or the VAFC (if I can't get a
really cheap price, I'm cheap and don't have too much $$$) so I am
thinking maybe along the lines of doing this:
450 cc injectors
B&M FPR and guage
1:1 FMU (if they make one, I think I heard from someone they do) or a
little higher ratio so I don't lean out in boost, but don't get the fuel
pressure too high either

Would that sound nice for a simple low boost turbo? I know the 450 cc
injectors will flow plenty, but going off what a guy said on the board
about just using 450cc and the FPR for fuel management he was able to run
alright, good but rich idle and just a little lean in the transition to
boost. I was thinking the 1:1 FMU would fix the lean transition and could
run a little better in boost. Maybe one step smaller injectors off a auto
eclipse with like a 2:1 or a little higher would be better?

Just thinking this turbo thing through and want to make a true low budget,
but somewhat reliable turbo without spending too much (LOW BUDGET).

 

damn, 450cc's for only 5 psi? if you want to run something liek that and keep it cheap just find a t-25 from a dsm and run a hot setup. with only 5 psi you should be ok. only problem is that a setup like that leaves little room for improvement.

 

well, I would increase the boost later on, maybe after a motor build up, or maybe if I wanna blow the motor and get another one, jk. But doesn't the T25 eclipse turbo hit 7-8psi? That would be too much for my daily driver.

With the 450cc injectors, I think I can get away with it if I turn the fuel pressure down to the lowest I can and maybe fine tune it, run a 1:1 FMU or smaller injectors (but bigger than stock) and run a 2:1 FMU or a little higher so I don't get too much fuel pressure.

Probably will never know until I try and tune for myself.

Anyone know what car has a turbo that has a 5psi max boost without a boost controller (greddy is 5psi or so, but can be boosted to 15psi with boost controller for example)?

 

thats not true. i know a guy here in phx who runs 8psi on a virtually stock b16. dynoed 256 to the wheels and not a dingle prob so far.

 

But I am running a D16a6. Rods aren't as strong as the B16 by far. But alot of people are running 8psi on stock d16a6's and ZC's on the CRX board and they have no real problem. Just wanna see any suggestions about the fuel management setup I am planning and what cars have low boost turbo's on them I can use so I don't go over board with boost commuting to work. I don't like hanging with saturns on the highway.

whoops, sorry, i thought you were b16 for some reason...

 

The 450's are overkill for 5-7psi especially when working with a stock ecu. Your stock 240s can do just fine up to 7psi with a rising rate regulator (fmu).

You dont have to listin to me but, I ran 380cc injectors in one of my old T-25 setups for about a month.. all I can remeber was going to the gas station twice a week and nearly dying from the smell of a rich mixture. and that was with the injectors down to about 22psi @ idle. You could get a Vtec controller and just pulse them a bit lower. I have seen guys use the Apexi (flashy blue controller) VAFC/SFAC whatever one does the Fuel mixture adjustment. Running 450cc injectors on their Turbo'd Gsr's and whatnot.. so maybe that could work out for you. But ****, an extra 600 more bucks you could have the Zdyne

good luck

This may or may not help.Cheaper ways to strengthen the motor for turbo application and HP. https://honda-tech.com/zerothread?id=116023

 

i dont get your question mang, pretty much all those turbos are adjustable, you can run as much boost as you want, if you wana know about efficiency: any one of those turbos will work with your setup, 14b, t25, t3 even a t04 will work.

 

http://www.homemadeturbo.com has all info you need

 

get a KKK03, from a newer VW. they work pretty well, except, you may run into reliability issues, unless its been rebuilt. A4's and TT just love to kill them turbo's.

 

If I'm not mistaken, I think he's asking what car comes with an internal wastegate in the 5 psi range. You can always go higher, but you really can't go lower without changing the wastegate, so he's trying to start low. I could be totally wrong, but that's what I'm getting.

Here is one quote from a 300ZX page (Don't know how accurate it is though)...

"A stock 300ZX has one of the most basic turbo systems available. It is a single, fixed pitch turbocharger (Garret T-3), with a stock boost of 4-5psi. "

 

Yes, you got me right, I am looking for a stock acuated 5psi or something around that range turbo from a car that is can be found in a yard in california preferably in the bay area.

About the 300ZX turbo's, you mean the newer generation ones or the older ones, a year if you know it would be great. There are many 300ZX turbo's around here so I can take a look.

Thanks alot guys for the great responses, I guess the 450cc injectors are way out of the picture, but with that 10:1 FMU, I think I would need a fuel pump to compensate for all that pressure.

Man, a Zdyne is looking better and better, even for the price of Gold.

 

i have an ihi turbo i will sell to you for $125 + shipping if you are interested.

 

Just a FYI for the Zdyne.

Do a "paired" buy with someone who is respectable, and bill will sell them to you for 800 each(savings of 150!!)

It's definetly worth the money, especailly when this is a daily driver.

 

yeah, I noticed those group buys on the CRX board. I go by ranudown on that board. Didn't you start the group buys? Well, doesn't look like I will get anything in the forms of a zdyne yet, but I am working my way. Once I am done, I will post up the aftermath.

 

put it on your motor dammit..!

 

i blew up my motor

 

oh

 

well I was, ONE of the people who started it. I was talking with another on the board( TedG.) and we were able to start the buy with Bill.

Great guy BTW

 

Saab's also have what your looking for.

 

Seen many saabs in my area, too. Probably some in the wrecking yard, but what kinda turbo and what is the minimal wastegate actuated psi of one of those?

 

dood, this kid is not ready for turbo..lol...that whole set-up just sounds ridiculous! If your gonna do it do it right.

 

What is so rediculous about the setup? Your probably right, I should just do it right the first time around, but money is so restricting. Maybe I'll just wait till I can afford a Zdyne and some 450 injectors. That would run a whole lot better anyway. Or maybe just get a ZEX system.

Would this setup sound rediculous:
SAFC/VAFC
450cc injectors
T25 mitsu turbo

I here people are doing this and it is a low budget way instead of getting the Zdyne. Has anyone had experience with this? On the dropshop site, they say it's real smooth and feels factory turbo'd.

 

If you need the car(IE, no beater to drive) for everyday driving, I would stick with a small 50 shot of ZEX.

now on the other hand, if you have the Time/Money/know-how, a turbo will tantalize every sense in your body. Keep in mind though, that there will be some sacrafices in durability, drivability, or reliability. Just something to keep in mind.
