I am looking for people that are running large amounts of boost on there SOHC and I am wanting to just find out what they are running and just get a feel of what I am lacking to buy and what to watch out for. Currently I have a Z6 block that I am throwing the Darton Permormance Sleeves in. I have a set of Stock Comp JE SRP Pistons and Eagle H Beam rods. I have a Y8 head that is being P&P and getting a 5 angle valve job. I will be running Uber WOOT WOOT. I have a T3 turbo, Greddy Mani converted to T3 flange, Greddy BOV, Greddy MBC, Spearco FMIC, Tial Wastegate, and a few other things that I can't remember. One thing that I am still needing are injectors. I just wanna see what everyone is runnin. Also I am gonna run a walboro 255 with a good FPR. I am just wanting a little feedback from everyone that has done something like this. Anything I should do different. I know it is only a T3 but will upgrade later. Also if anyone has a map form Uber running this much boost I would GREATLY appreciate it to give me something to compare to. I have a 96 coupe if you were wondering. But any input is greatly appreciated.

 

How many ******* boards do you post this **** on, calm down man

Hahaha...

I think it's funny when I visit turbod16.com or homemadeturbo.com only to find the exact same threads that are on H-T!

We are probably all members of multiple forums so posting in all of them will only get the same response from the same people! Good stuff

Anyways,

Sorry I don't have any good info for you about 20psi daily driven... what comp ratio are you going to run? What is the limit for pump gas? I remember a chart in Maximum boost that talked about how much boost you can run at what comp ratio and what octane gas before you risk detonation...

I would think if you are going to push 20psi you better have super low compression or run race gas... but I don't know much about that... I have yet to build my engine and get to experience &gt; 1bar of boost....

Oh, and what turbo do you have? There are so many different sizes of the T3... not that it really matters if you are shooting for a psi goal and not a horsepower goal...

 

ppl with sohc turbo dont run 20 + psi... wayyy to many blown head gaskets.

 

LOL . Sorry for the repetitiveness but I have gotten a different answer from every site. I have heard of quite a few people that run that much boost on d blocks. As long as everything is correct and you have the block and head decked and use a good gasket with ARP's I don't forsee much of a problem. Also why do you not like the Y5 boosted. I have an Hx but I am pulling the motor as you have read.

 

i dont like the y5 becuase its hard to find parts for it like gaskets and ****... oem parts

dude i run 30 psi with stock head bolts and i dont blow head gaskets its in the tunning man!!!

 

You may want to consider tapping out larger headbolt holes and getting some larger ARP bolts to combat D series headlifting. I think the Bseries are .5 inch and the D's are .25 inch?

You sell your motor yet? or going to keep it now?

 

what are the specs on the turbo? 20 psi is different for every turbo. the key to remember for how much a block can handle is not psi, but hp. 20 psi on a small turbo will produce less horsepower than on a bigger turbo.

are you going to micropolish the crank, balance the piston and rods, upgrade the bearings? i would also not use the stock head gasket and go with a Cometic (sp?) one.

for injectors, goto RC Engineering's website. They have a formula thing that starts you off at your targeted hp and then you find out what size injector you need.

also, how are you running a Tial wastegate on the Greddy manifold?

and 20 psi daily on pump gas is unrealistic. unless you have a major conservative tune, 93 octane is very low to run 20 psi. i have friends (supras, turbo tsi's, etc) that can run 20 psi but don't due to pump gas. race gas, different story.

 

if that's a straight t3 your running 20 psi shouldnt be a problem...i know a guy running the afc for fuel management and he runs 15-20 on his stock block y8/y7 for a while now without any problems...

I had been wondering if this was possible are people doing this?and with success?

How much power is he pushing stock thats pretty impressive

Not to mention... do you understand what kind of gas mileage you are going to get with 20psi? Not good at all, especially for a daily driver...

I don't know how much you drive but running 20psi daily would cost me like a ton...

Then again, I drive 15 miles to and from work every day... maybe you don't...

I just wouldn't want to be filling my tank every other day with 93 octane gas, that would get expensive really quickly... that's why I have a beater that I commute with

 

I think 20 psi on any honda daily driver is just retarded... I mean, there is no reason to risk your car every single day you drive it. Why not settle for 10-12 and then turn it up when you are going racing or to the track. But if you feel the need for 20 psi daily be my guest.

 

There was a guy here locally runing 20 psi on 8.5:1 cr. The turbo was t3/t04e 50 trim of course all pump gas and he was blowing head gaskets like once a week.

 

20 psi is not that much. 300 or so on a d series.

i will be running that daily

platinum.

 

I will run low boost at first but once I get better tuned I will turn it up but probably just at special times. I will more than likely end up running 12 daily when I am commuting. Thanks alot for the input guys. Keep it comin.

last time I checked, 300 or so is a decent amount on a daily driven single cam.. yes I know many people have put down well over that and have success.. But why risk it. I am not saying that 300 or so on a D isn't reliable either, I am just saying why not just save it for the track or when you need it, ( a dual stage boost controller).

proll not that much...im suprised the car still runs haha...it dynoed 188 at 13 psi i think...

why would gas milage suffer at high boost? its not like you floor it everywhere you go...and if you do you deserve bad gas milage...part throttle tuning is irrelavant to full throttle so no matter what boost your running gas milage shouldnt change...

 

My response was left on HMT. hahahah

 

20 psi on pump gas and daily driven is not impossible or stupid by any means. All you need is a good tuner and a conservative tune. It's been done by tons of people in the past.

 

LOL I appreciate that Stealth. I have come to the conclusion that I am just gonna run the dual stage boost controller and it will solve most of my problems. Thanks for the info guys.

And wait a second, no, it isn't unrealistic at all. My B16/B17 hybrid is at 8.8:1 compression and my car is tuned to 18 psi on 92 octane. Evo 8's run 19 pounds of boost stock on 8.8:1 compression. I have lots of friends with talons, and 24-25 pounds of boost is about the limit on an 8.5:1 2G motor and pump gas.

 

All depends on the CFM capability of the turbo ex. T25 vs T66 haha. T25's run all day around 20PSI, but they are hairdryers. Run at T-66 at 20 PSI and look the F@ck oUt!

thats true, but they are design from the factory for that. plus he never mentioned what comp. ratio he is running so i guess we couldn't make assumptions.

 

I am running stock compression pistons.
