GT-FOUR El Franjeado, EFR turbo etcq Options

[Neon90424]

I'll take advantage of this and say hello as this is my first post in this forum. I recently acquired a GT-Four from 1999 randomly traded my 2003 celica Gt JDM ofcourse was a neat ride but too low gas mileage was good beat the **** out of the car and of course... wrong wheel drive :S... So I kept driving past this pretty GT Four and I decided to check it out the next day... My cars underside was beat to hell ( rocky roads speed bumps carter looked like muhamed ali punched it) He said No mechanics or the deals always go sour, sure what the hell my car was beat to **** and ate cans of oil. I tested it and sure for me it was like driving a missile. So now the details, I liked that it had a nice thick Aluminum KOYO racing radiator and a Cusco alloy strut brace and a sweet japanese roundish air intake and 57K kilometers on the Odo...the limited 300km/h TRD speedo so I was turned on by this and the next day I was drivin this gas guzzler home...No surprise it had problems....

So the damage is this blown turbo seals no idea of what the engine condition is my intake manifold and everything else is covered inside with oil...

I came to the US and bought basically 2 grand worth in parts didnt have that much money so I had to compromise, Heres the list, try not to cringe. Im basically gonna slap all this **** together and see if it works...

GODSPEED KKR 480 Twin scroll turbo ( says its 450HP capable I'm aiming at 350)
4 Iridium spark plugs heat range 7
HKS SSQV black limited edition BOV
AEM Water/Meth Inj 5 Gallon tank (our gas aint so purdi)
Ebay oil catch can
Timing belt set with new water pump (dont need the water pump but taking it as insurance anyways)
ACT 6 puc clutch disk ( stock clutch slips a bit under high rev launching)
crappy chinese AFR narrow band digital clockything (just so it tells me Im not melting pistons
25mm ebay wheel spacers
ebay electronic boost controller
ebay n1 carbon fiber burnt tip muffler
electric exhaust cut out from Raceland USA
carbon fiber raiser blocks from hong kong and the normal GT four wing for 40$ off a local supra guy.
cheap 25$ bishieclipse FCD
Ill try to update once I get to Paraguay and slap all this stuff on, Should be fun to see the results...

Cheers

Well NEON90424 there are still some options that you could take in regards to improving your fuel system on the cheap.

One thing you could try is an improved fuel pump, with an aftermarket pressure gauge/regulator. With this method you can get the most out of your stock injectors without actually changing them.
I will say though, that most people tend to shy away from doing this mostly because they dont know what they are doing or because someone tells them that it isnt a good idea. READ UP ON THIS TO SEE MORE OF WHAT I MEAN....(btw this method takes a bit of research and patience) Stock fuel pressure is as follows...33-38psi/idle =27-31psi


AEROMOTIVE FUEL PRESSURE GUIDE

You could also try swapping out your stock injectors for something slightly bigger out of a junked car. What i mean is, finding side feed 550cc injectors to give you a better range of efficiency before you hit that magical 80-85% duty cycle.

I have seen a few friends of mine get away with this when doing their "junkyard builds (using mostly parts out of a junkyards)". I really wouldnt reccomend this as a permanent solution mostly because the injectors could be bad, and you might have to do some custom work to make it all work together (aka. boring out rails, jury-riggin a rail to work with your engine etc.etc..)
Ill post up a link that has list of all side feed injectors and their flow rates.

SIDE FEED INJECTORS

OR you could dig through forum sites/ebay to find a nice set of injectors on the cheap you could use. Use a SAFC for cheap tuning and throw in a wahlbro pump and bam you could have a cheap system that works and is reliable to some extent. Although some ppl say that they have problems with the SAFC and the 3rd gen's computer...meh

All of this is really just food for thought. I understand that you are just doing a simple build using "cheap parts". But i figured i would at least throw the info out there if you or someone else was curious about other methods.

Honestly when it comes to upping the boost, and fueling etc. etc. i would do things right, no matter the cost. Those two things could easily detroy an engine if done wrong..

Anywho ill stop clogging up this thread with my post...good luck with your build man, and dont listen to what anybody says...hopefully you keep things safe though, and you get some fun out of it!!

...and dont listen to what anybody says...

I just thought that part was funny lol.

I have a Walbro 190LPH pump in my sand rail I can swap that out into my celica I guess wont the stock FPR do its work? what PSI is the 80% of stock limit? Also you guys are forgetting the point that im not going to be going 7000 rpm for 10 minutes...

Hi,

the main problem of a 100% duty-cicle is that the injectors gets hot as the fuel is't not longer able to cool them and in front of this they get damaged, 80% is a safe maximum

a friend of mine is driving around ~380PS (DIN) with the standart 540cc injectors, a good fuel pump, map and especially water injection is needed

you should possible go for a hybrid turbo to hit your goal, i think this is the cheapest solution as you don't have to build the whole system new

greetz

I guess you didnt read the part where I wrote Wat/Meth injection will be set up...

I already got the turbo its a twinscroll .50AR chinese piece of shart
