I know there is threads on this but none answered my question.

Just wana know how many pounds or horsepower i can throw at my car through boost. Also what kind of oil is recommended.

b18b1
t3t4 (to4e) chinese
3 inch downpipe.
New piston rings
New rod bearings
New water Pump
obd-0 to 0bd-1 pr4 (crome)
2.5 charge pipes
Side mount Intercooler (about the size of eg radiator)
Stage 3 clutch(6 puck sprung)


Please let me know guys

 

Use the threads you've found. no one will answer this question for you, because it can't be answered. Good luck.

Also, this is technically against forum rules

"There is no acceptable use of racing here unless it pertains to an actual track event or drag event which produced actual results. No guessing contests on power are allowed either."

 

There are a lot of thing that come into play when you ask how much boost. Things like max power goals, turbo efficiency, intercooler efficiency. A stock healthy B18B1 can do around 250-280whp safely. The turbo you are going with is a good choice my turbo build is using the same spec turbo. A larger from mount intercooler would be more efficient and drop charge temps better. Get some 750cc injectors and a 255lph fuel pump and have the setup tuned. A good tuner will know the limits of the set up. Dont try to push it past 280whp or the rod bolts or sleeves will give out. Now how much psi it will take to get there as I said depends on the efficiency of the turbo and the turbo system. As long as your intercooler is at least 60% efficient and has a low pressure drop 8-10 psi with a TO4E .50 trim .57 compressor .63 AR turbo will see 220-280whp on a B18B1. A Vtec head will get you closer to 300whp on the same boost with rpms to play with.

 

Thanks neal.... im getting 550 rc injectors or dsm 450's.
Forsure a walbro 255 intank.
I dont have a goal as far as power or psi goes. just a fun safe daily driver.
Only thing i know is im not gonna go passed 10psi.

How efficient are these chinese turbos? (it has shaft play)i am getting it rebuilt though.

 

450cc injectors will be nearly maxed out at near 220-250whp depending on the boost need to get there. It is never a good idea to run an injector at near 100%. Go with 750cc and leave yourself some room. I am going to use a ebay turbo either a CXRacing TO4E which is made in USA or a JDM Sport TO4E which I have heard good things about. As long as it is rebuilt correctly it should last a good long time.

 

Those injectors can be taken to over 300whp. esp. if you have adjusted your base pressure. Don't spread false information please, there is enough of that on the internet.

 

Ok i know 750 cc is alittle big since im not gonna be on high boost.
and yea ima have it rebuilt at a local shop called Turbo City.

Is it ok if i do ob0-to obd-1 and run a pr4 and get tuned on crome? or crome gold.?

 

There's a thread just for turbo ls motors. I know damn well you didn't ask in there because you would of gotten an answer immediately. Secondly psi means jack ****. A larger turbo will produce more power on the same psi then a smaller turbo.

 

Look at the thread its got Like 15986 pages. Why read and thread jack when i can ask my self.

If your gonna drop lines like that than Just like your picture says!!!

 

Yeah why read a few pages and possibly learn something. God for bid huh. You're not thread jacking anything. It's an information thread. Instead you start a new thread asking the same dumb question for the 2,000,000 time now.

Man I love ignorance.

 

 

I have researched those injectors and after doing the math 250whp requires 433cc injectors so 450's would be nearly maxed out. And increasing fuel pressure to squeeze more out of an injector is not the best approach. What happens if there is a decrease in fuel pressure that you motor is now more dependent on to run a correct AFR? I do agree that I have seen 300whp on 450cc injectors but it is very dependent on boost pressure. A more efficient turbo setup with a good flowing head will make the same power on less boost as a stock motor with a poor turbo setup on it. I always go bigger when it comes to injectors.

 

I would really suggest using a Hondata even if it is the S100 (I use the S100). Crome will work but Hondata is just overall better. I know Crome is much cheaper but spend the money where it counts.

 

So you're telling him to spend money where it counts... Well with that logic he should be buying a quality turbo instead of some chinese ebay brand paperweight. S100 is outdated now. Crome has been used by many people with great results. For a stock ls turbo setup it's more then capable of doing what he needs it too. Op here is a chart that was compiled by Jeff Evans of Evans Tuning "one of the great tuners on the east coast" it will give you a good idea of what you need to do. 440cc injectors are enough for 300hp so keep your dsm injectors or get some 550's or 750's "IF" you plan on going for more power down the road.

i have dsm 450 blues. but my boy has 550 rc's for a good deal.
just dont wana blow out my only car.
and as for sc3 why should i buy a good turbo? when im not looking to make huge numbers

 

Do your RESEARCH, I'll BUILD fast cars!

 

Because a good turbo does more than make any power, it also may save your only engine. When a turbo destroys itself, there is a possibility of one those cute little pieces or debris to get into your "only car".

 

Thank you Mac. Glad some people share the same opinion on certain things.

 

Understood.
what would make it blow? (turbo)

 

Yes. It's made with cheap parts and probably not properly balanced. When the bearing fails and the wheel that's made of thin chincy metal makes contact with housing. Then it breaks into small pieces that get sucked threw your motor and destroy things like valves,pistons,cylinder walls. Now you have a ruined turbo and motor. When spending the extra money and buying a quality turbo in the first place would of prevented all of this.

 

Yeah the china made turbos are not balanced worth a crap and something that spins at 100,000+ rpms needs to be perfectly balanced. For a decent inexpensive turbo JDM Sport is not bad. S100 is not outdated, no more than Crome is, it is just basic but still has plenty of functions for a street car like full tuning of coarse, boost control, no3 control. And I did also say that 450cc injectors will do the job, but IMO a little bigger is better than just big enough. You dont have to agree with me.

 

Cool.

Sc34 how many china turbos have you seen brake?

 

JDM sport, god speed, xspower all the same junk from the same factory.

 

^^^^ EXACTLY! I'm sorry but if something of proven quality has a price tag of $700 and then a Chinese counterpart has a price tag of $200. That sends up a red flag. Yes, people have used them and had no trouble but the ratio is not good. I'm sorry but I would never by a Chinese knock off of anything that could mean the end of my motor ie. turbo,wastegate,boost controller,fuel pump ect. I wouldn't even use a knock off blow off valve. I'm not going to spend money on something that will just have to be replaced by a quality part later on. I don't have money like that to waste. Build it right the first time around and it will last much longer and be trouble free so to speak. Boosting a car is not something that can be done cheaply. There are certain things you can get away with. Many people use front mounts from eBay with great success. I'm running one myself. People use cast log manifolds from eBay. Personally I'd buy a Blox manifold for the extra $60.
