diy turbo..

[lucky03602]

hello. first off i have a 90 240 with a ka-e in it. with tax time here im highly considering buying a turbo kit i found (has mani, t3, dp flange, and 38mm wastegate) and buying a bov, 360cc (at least) injectors, adj fpr, and a walbro 255 pump.

well i would like to install it all on my own, and luckily i know a guy who swapped a red top into his car on his own (hes a mechanic) so ill be using his help as well if needed but does anyone knw of a site that gives you the basics of what you need to do to hook one up into your car?

obviously i have never dont anything at all with a turbo but still i like to do my own work.

2nd is i would like to get right now basics to get the turbo in my car running at 5psi max effincently (for now) so if theres anything i might have overlooked in my little list of parts im gonna get plz tell me

also if any questions plz ask.

no i didnt search on here for a webpage but i have been searching off and on for a while now about turbos and misc stuff about them.

You need intake piping, an intercooler, oil lines, a downpipe, and some kind of fuel management(most likely safc or emanage).

If you need sites, look through the faq thread at the top of this forum. It will have links to everything you need to read to get on your feet. Good luck.

i knew about the intake piping and for the downpipe i figured id probibly have one made unless i do come across one (ill be looking anyways)

i knew about the fuel management (i call it a piggy back) and just forgot to put it in the list

do i seriously need an intercooler tho? in that case ill be looking for that as well.

i knew the turbo runs oil through it, but where do the lines come from? (where off the motor do you run the lines off of to the turbo?) i will search for myself anyways but thought id ask here.

and thx for the faq, i never even thought about that, just always used search button.

pretty good thread:

"SOHC Turbo Build for Dummies" by veilside180sx:

ok did a quick look at it and it looks like i will be using that for a base idea. thank you.

heres the kit i plan on getting:

turbosmart 38mm wastegatedp flangeka-e t3/t4 manifold

and for turbos i have a choice"t3/t4 turbos .63/.70, .48/.70, .48/.50, .36/.50, .36/.70

i have no clue what those numbers mean but ill learn none the less

then i plan on walbro 255 fuel pump, probibly type s bov (cheap on ebay yell at me if im wrong) 360cc or 450cc injectors, probibly 360ccc (cheaper then 450 on ebay as well) downpipe will be made 2.5" to high flo cat and 2.5" all the way back ( or no cat at all i dont know)

everything i saw said get a safc2 and emanage? also im told to stay away from rrfpr so ill have to check back into that one, how am i doing so far for basics?

[onosqv]

keep reading the threads & stuff buddy, ppl aren't gonna spoon feed you all the information. read thru threads here, ka-t, etc.

100% of the questions you have asked so far can be found w/ a little searching, or simply just going through the pages and reading.

For starters, you should at the very least read "how a turbo works" at "howstuffworks.com".

Then there is Corky Bell's turbochargers book, which is a little outdated, but provides a very good basis/foundation to start on.

Good luck, but don't post back til at least you have done some real research on your own.

[lucky03602]

haha funny thing is i started to read how a turbo works lastnight, but it was getting late so i went to bed. from what i gathered its run off the exhaust fumes that spins a turbine that sucks in more air therefore the engine gets more air and need to add more fuel to compensate for it and thats where the power is from.

as far as asking how im doing so far i ment on cheap stuff (type s bov) and i am currently searching while i have this thread, believe me.

not to be mean but maybe you should consider the fact that the little bit of information i do have is from researching and writing down info and not asking questions. the only origional question i had was "do you know where a site is that'll explain how to install a turbo"

also theres ppl out there who run a turbo with just an rrfpr or just a walbro 255, no tuning or nothing. ive read that that is just moronic (no offenense to anyone) and thats not what i want.

You can save yourself a few bucks and headaches by installing a FMU instead of injectors and SAFCII. I ran it all the way up to 8psi on a dyno with mine and had a good A/F all the way to redline. Also it is a lot easier to install and you really don`t have to worry about tunning it. Just make sure you install the Walbro 255 and you are good to go. Later when you want to go higher boost you can take it out and sell it. I personally think for beginners that is the way to go.

[lucky03602]

ill look into that. thx

[lucky03602]

okay so an fmu is basically a rrfpr from what ive found. basically as the pressure inside the turbo rises it releses that much more gas, and a 10/1 fmu will relese 10 more lbs of gas for every 1 lb of boost. am i correct in this?

[AeonTorpor]

Yes. That's not the way I would go though. That puts a lot of stress on the injectors. I'd go emanage or safc or something like that. And like the dude said, not really good for more than a few psi. Try running FMU when you are at 20psi

[WDRacing]

For low boost the FMU works awsome...

Easy to install and the outcome is great. The additional fuel pressure IS NOT a problem in any of the cars I've seen or know of. So long as you stay a low boost, like under 10 psi.

[lucky03602]

yeah i dont plan on going above 7-8 psi max. im not aiming on making this car a 10 sec car or nothing (example lol) just something with some power behind the wheels and the nice sound of a bov. i mean ill eventually bring it over to epping nh and drag with it here and there but mainly a daily driver.

so since im running low boost ill probibly be going with the fmu and later on ill upgrade to a safc or emanage.

[WDRacing]

Sounds like a great plan, you can sell the FMU when ur done with it.

[yessir240]

while running the fuel management unit you still need bigger injectors and a new fuel pump??correct?

[s13drft89]

Is it necessary for a pump at 8psi on a fmu??

[lucky03602]

i cant say it is or not, but im upgrading my injectors to 370cc and upgrading my fuel pump to the walbro 255. later on i plan on making a little more power so getting that stuff now will eliminate a step later.
