OK, I have finally decided what to do.....4G64T

After doing more thinking and doing some research I have decided to simply turbo my good 'ol 4G64. I have been reading up on how to do it and I found this site that has alot of good info: http://www.4g64.150m.com/. I will be honest with you, I don't know alot about turboing a car or turbo cars in general, I only know the basics. So some of my questions may seem "newbyish", but please don't flame, just help if you can. My plan is to turbo the stock SOHC 4G64 and retain the stock ECU.

So anyways, I have some questions.

1. What would be some advantages of swapping to a turbo ECU and should I do this?

2. I am obviously going to have to upgrade the fuel system. I was thinking about 450cc injectors like the link above stated. If I switch to a 2g turbo ecu will I still need the SAFC?

3. I will upgrade the fuel system with a Walbro 190 pump and some injectors. Besides an SAFC what else will I need. Will I need a fuel pressure regulator if using the SAFC?

4. Will I need any additional tuning besides setting boost and tuning the SAFC?

5. I want to run around 8 psi for now. I may eventually build the bottom end and do the DOHC head swap so I can turn up the boost. With this in mind what will be the best turbo to install. The above link suggested a small 16g or a 14b.

6. I will use an aftermarket FMIC. Can I use aftermarket 2g turbo lower and upper intercooler piping?

These are all the questions I have for now and I appreciate any help given.

I am hoping to start on this sometime this year. I have enough to cover it all in my savings but I want to get a job first so I dont blow all my paper.

1. Swapping in an EPROM will let you run DSMlink. If its possible, I'm not sure.
2. If you are going to be running a 14b 450's should suffice, otherwise go bigger. I think you will still need some sort of tuning device because the turbo engine is only 2.0 and yours is 2.4. Again, not sure.
3. Assuming that the fpr in the 2.4 is the same as the 4g63 you will be fine with a 190. Either way, I would get an aftermarket fpr.
4. Dont really understand the question.
5. I'd go 14b for a while. I think you may be stretching those injectors with a 16g.
6. No since the stock pipes are for the SMIC.

1. What would be some advantages of swapping to a turbo ECU and should I do this?

To have the fuel/timming maps for possitve pressure..

2. I am obviously going to have to upgrade the fuel system. I was thinking about 450cc injectors like the link above stated. If I switch to a 2g turbo ecu will I still need the SAFC?

Any injectors larger then the 450's will require some type of fuel mangment..

3. I will upgrade the fuel system with a Walbro 190 pump and some injectors. Besides an SAFC what else will I need. Will I need a fuel pressure regulator if using the SAFC?

You will need a 2g turbo FPR set to 43.5psi, 440's and no other tuning device... If you choose to get a 255lh or larger you will need an AFPR that will allow you to lower your fuel pressure; like the Aeromotive 13109..

4. Will I need any additional tuning besides setting boost and tuning the SAFC?

If you choose to use an safc2 you will need a pocket logger to log RPM, Timing, 02, Airflow.. And of course a Wideband if you have the available $..

5. I want to run around 8 psi for now. I may eventually build the bottom end and do the DOHC head swap so I can turn up the boost. With this in mind what will be the best turbo to install. The above link suggested a small 16g or a 14b.

both have extreamly good compressor effencys for low boost.. The 16 just has a higher & wider effency... Choice is yours.. I would stick with the 14b to begin with becaue it won't outflow your walbro & 440's..

6. I will use an aftermarket FMIC. Can I use aftermarket 2g turbo lower and upper intercooler piping?

The UICP yes if you go long route, LICP, No.. You can get a suppra side mount to work with the stock intercooler pipeing... Most FMIC will require new pipeing...

Thanks for the help from both of you guys. I have another question. If I swap to a turbo ECU will I need the 2g 4G63t throttle body? And if so...why?

Any injectors larger then the 450's will require some type of fuel mangment..

So your saying that if I go with the Walbro 190 and 440 injectors with FPR set to 43.5psi that I won't need an SAFC?

You need the 2g Turbo FPR, and it needs to be set to 43.5psi... You won't "need" the safc2. To do any tuning you'll need the safc2 pocketlogger combo..

You wont need the 2g TB, you can use the 1g TB with 2g TPS, Vfaq or RRE has a writeup about it..

this really doesn't answer your questions at all and anyone feel free to correct me if i am wrong, buit i was reading some insructions posted on another forum about turboing the 4g64 without rebuliding to a dohc and i believe that if you stick with the sohc you can only run low levels of boost something like around a max of 10 maybe 12 psi, so that might be something to think about if you are looking for a big power gain or want to run a higher boost level.

Thats because it has higher compression

Yeah, well I'm only wanting to run around 8 or 9 psi for now. I'm just trying to get all the parts together right now and get it working. Later on I'll slightly upgrade the bottom end and do a head swap so I can turn up the boost.

i think that you should get a motex system exhaust............or so says brian..........but hes a cop so he doesnt really know. I have seen fast and the furious 100 times so i know a lot about cars, like nos stickers give you 10 horsepower.....and if you have a hose hangin on the road cuhhhhhhhhh man bruh man you tearing up the 1/4 so watch out.........i could help you hook up something being that we home bois.....holla at ya boi because i..........have an ideahttp://www.automotiveforums.com/vbulletin/images/icons/icon3.gif

Dude, you trip me out. Good to have you on the forums.

you want your car to go fast i mean seriously are you crazy in the head:screwy::banghead: and anyway why you asking us about all these illegal parts for..................you a copppppppppp:nono:

hey brah man why you even got stuff about your ferrari on a mitzu forum anyway dude.........you must be smokin that japan stuff :smokin:

No way, your a cop? :lol: I nominate your life as the biggest contradiction of the year ;).

EDIT: Shit my bad, I missed the F&F reference...

He's going undercover into the underground street racing to catch the bad guys in green honda civics...

Shhhhh! Don't blow my cover. Keep it on the D L.

But seriously, let me ask you another question Scottsee, I know, I'm stupid.
Lets say I keep the spyder ECU and simply run the upgraded injectors (440's right?), a Walbro 190, and a FPR. Will this work with the spyder ECU? I mean its not gonna try and lean out the fuel ratio under WOT right?

And my car has high impendence injectors and the 2g turbo cars have low impendence injectors. Does anyone make High impendence 440 injectors for my car or will I have to use injectors ment for a 2g turbo and wire in a resistor pack (I hate to do it, but I will if I have to). Thank you once again.

The project should be getting underway soon. I've already started sourcing parts.

if you do this:banghead: you will look like this :icon16: i dont know what this has to do with you brah but i just felt like doing something, but on some real though i need to know if anyone on here has a mitzu for sale, i prefer a eclipse.......not really a spyder if someone has a eclipse for sale ill give you plenty of these:2cents:

What the hell are you talking about?

if you dont know what im talking bout then dont reply iight go to the stupid ricer chat.........i think its called kidplanet.com or something.........you on the wrong forum:disappoin

You have alot of balls for a noob, if you want a car look for one. carsoup, ebay, autotrader ect.

i just have 2 balls like everyother dude, they may be bigger but i dunno, lol, thanks dude, if you come across a good one do ya boi a favor and tell me about it iight brah :sunglasse

Well where are you located and what are you looking for

im in nc, id go anywhere in nc for a car if its good you know, i stay like 5 minutes from vanilla gorilla he is my brah man, but umm i wouldnt mind having a spyder, its just that i might need a little room, i like the eclipse gsx, but i dont have a lot of money right now, i want a turbo.....but then again i dont know much about cars, i have been looking, but if you come acrost something pretty good, holla at me

who the fuck is that guy? Is he black? or is he Korean? Boii = korean iighht brah = black man saying brian? wtf? Calm down Tyreese

whoaaaaaa mexrocket..im indian, you know american indian.......you got a nice car.....how fast does it run......from the pics im saying how ever fast you can flinstone yo ass around, lets see mexican.......hmm im guessing its gonna be a van.....with 40 other mexicans in it and a towel dispencer for your wet back..........pimp my ride exclusive..........you off tha chain

No need for raciest comments, good way to get banned.

i wouldnt of had to say anything if you wouldve just let me be....... i said nothing to you until you said something im happy about what i said..........i think i stated my point...........but really............how fast does your car go...........i know i dont have a car but man...........your about as bad as me.......i mean look at your "car" i mean frame.......my advice for the day..........RENT A CAR

I'm pretty sure that isn't his car, he drives a 1g and it runs....sorta:lol: Not to be an ass but if you want to last long around here you need to change your attitude

your right, i dont want to get kicked off, i think i can make some friends here.......besides vanilla gorrilla he is my home boi........and i think that i can learn alot about cars. It would just be hard for me to sit back and take that crap ya know man, but i aint gonna say nothing, that was funny what you said about it runs.......sorta, props man

Its not just his, its all dsm's:rofl:Half the people on here pulled their motor over the winter and my talon is sitting with no head:)

Finnally, clear typing... good change. How could you think that the frame was my car? lol. Just chill man. And the car runs =P lol. I am just waiting for nicer weather to fix the return it's like 20 degrees.

iight man i was just joking around anyway, i mean at least you got a car, i get my lisence in september..............o yeaaaaaaaa it will be on then, lol, but umm i hope it comes out looking like you hope, i think i spelt license wrong......o well peace:banghead:

well everyone im out for tonight, ill check you all out tommorow, it was good meeting you all, pr, mex, yall keep it real, dont do anything i wouldnt do:smokin::evillol::banghead::icon16: god i love smileys, lol

Its not just his, its all dsm's:rofl:Half the people on here pulled their motor over the winter and my talon is sitting with no head:)

Mine works lol I gues i am better off than half of you haha.

Mine will be joining the ranks in about a week and a half, the head will be on its way out to replace the timing belt, head gasket, and head studs.

Mine works lol I gues i am better off than half of you haha.
You're also N/A:p

You're also N/A:p
hopefully not for much longer. as long as the money all comes together and the figures i get back from the shop don't top like 6 grand I won't be.
I will be blown and spankin some domestic ass this summer

Uhh... why don't you just do it for less than 2k.....

Yeah, I gaurantee you when I'm done with my turboing I won't have more than 2K in it.

sup everyone im back on the bricks:banghead: grape ape is in tha houseeeeee and i brought plenty of :smokin: and some :2cents: 2 buy some more :naughty: pr, mex.......yall down:rofl:

i kno my bruh man cuh man vanilla is in cause we bois till we die LOW EXPECTATIONSSSSSSSS

This is a prime example of what we call post whoring. And you guys thought I was bad :shakehead:

Uhh... why don't you just do it for less than 2k.....

#1 I want it to work
#2 I am not just going to put ona tiny t-25 bosst 8 psi and call it good

I am going for at least 350 to the wheels on pump gas, the turbo piping and intercooler alone even from ebay would be over 1500, not to mention new rods, pistons, head and ecu.

what kind of power you lookin to get?

$1500 for an intercooler and turbo piping on ebay? What the hizzle. Thats is crazy. You can buy an intercooler core for $150 and just make your own piping for a-heck-uvalot cheaper thank $1500. Thats what I'm doing. But whatever, waste your money if you want!

what kind of power you lookin to get?

Right now I am just trying to gather all the parts to do it with, and then just get the basic turbo system working. I only want to run a 14b and at first just keep it around 8-10 psi. Then I am going to upgrade the clutch and LSD. I will be content with this until I finish my helluva suspension system, after this I will slightly upgrade the bottom end of the motor and maybe a DOHC headswap, then turn up the boost. That is basically all that I want to do to this motor. If I'm doing around 230 at the wheels or something I will be happy.

Because me personally, my car is just gonna be a well rounded platform and daily driver. I don't care about big dyno numbers. I don't want to have a monster engine. BUT TO EACH HIS OWN! Do whatever you want to do.
