Evan G Posted August 16, 2009 Report Posted August 16, 2009 hi people, i got a turbo from a bmw 335i, its a 1.5L turbo that runs from 3 exhaust ports I'm planning to run 6 - 8 psi bog stock engine carby on the inlet of the turbo (10 pounds on fresh engine) questions.... how long will it last before KABOOM also i know i should decomp the engine, can i use a 3k bottom with a 4k head? its on a budget TURBO PICS yoooohooo taz_rx where areee youuu Quote
Jimpoole Posted August 16, 2009 Report Posted August 16, 2009 Wow that is small. You're drawing through? Is that really a good idea? Are you using an aftercooler? And have you read the FAQ yet? Apparently these shitty 4k's don't last long over 6-7psi. Stolen from the FAQ: Some general rules for forced induction on K motors are: don't go too big, and don't run lots of boost. A stock K motor can handle 6psi quite happily, at 8psi their life gets reduced noticeably, and they go bang pretty often at 10psi. And 6psi really is jack-shit. Quote
Evan G Posted August 16, 2009 Author Report Posted August 16, 2009 nah no intercooler, yes i have read the FAQ 3kc head on 4k = high comp how about 4k head on a 3k? low comp? i think on 10psi with no intercooler I'm gonna have problems with dentonation/pinging wheres raz_rx when you need him :P Quote

Jimpoole Posted August 16, 2009 Report Posted August 16, 2009 I think on 10 pound you're going to blow the shit out of your motor, not only problems with pinging. Try shit like this on something decent, like an escort. 4k's are a bloody joke. Quote
chin70 Posted August 16, 2009 Report Posted August 16, 2009 I'm planing to do the same thing but i got a exa turbo and a small intercooler Quote
SLO-030 Posted August 16, 2009 Report Posted August 16, 2009 There are a few guys on here running in the region of 20psi on 4k's and they are still running. Quote
Evan G Posted August 16, 2009 Author Report Posted August 16, 2009 the turbo is sooo small i reckon a 4k will spool it at 1 grand :P Quote
Jimpoole Posted August 16, 2009 Report Posted August 16, 2009 There are a few guys on here running in the region of 20psi on 4k's and they are still running. But at six grand shit will fly Quote
Teddy Posted August 16, 2009 Report Posted August 16, 2009 this better not turn into a negative $hit fight, there'll be some warnings thrown around ... :P Best of luck with the project, ill be interested to see how it goes :P Quote

Try shit like this on something decent, like an escort. 4k's are a bloody joke. mate your a joke if you think 10psi is going to blow the shit out of a 4k. I have had a sc14 on a 4k running at 16 psi for a year now. So unless you have done it don't diss it :P good luck with the build mate if you build it the right way you could get any where upto 180kw Edited August 16, 2009 by **chumps** Quote

So unless you have done it don't diss it :P good luck with the build mate if you build it the right way you could get any where upto 180kw whats been done to the engine? draw thru or blow thru? carb info i think i read your topic about blowing away a supercharged stato LOL! keep it tup Quote
**chumps** Posted August 16, 2009 Report Posted August 16, 2009 Bottom end was standed had a spacer plate made up, ported head with draw thru twin 42 and a oil cooler and that on the right tune made 100kw easy. ATM i am working on a 5k to drift with its going to make 150kw safely, you just have to do things right in the first place Quote
Evan G Posted August 16, 2009 Author Report Posted August 16, 2009 jesus :P do 4k heads fit on 3k? (decomp the engine easier?) Quote
