Hey boys this is my first post with magna forums.


I am cunnently trying to building a sigma turbo with a TR magna injection setup on it..

I am trying to build this car within a budget..

I want to know if i could run a turbo with a stock inlet setup from a TR??


Is this is possible How much PSI could i run before i need to get bigger injectors and after market fuel managment??


I already have a Electric fuel pump so fuel isn't a huge problem at the monent.(other then the price) :cry:


All information is going to be helpfull.

Thanx boys

SCotty

from what i know the magna injectors are fairly large especially for na cars, i am unsure if monga is using stock injectors (and i wouldn't be surprised if he is) and he's running 10psi, they would definately be the go on budget.

From wat i have read u use 13b injectors.

PPl have said that they are good for the setup..

I jst need to no if the ECU will handel the boost.


Im happy to run 10 Psi untill i get my wolf 3D system some time next year.

Still need help boys


SCotty

you'd definately need one of the ecm chips, no way could u run 10psi off stock maps if thats what your asking, it'd run lean as. If your just replacing next year theres a few you can get bought and installed for under a grand. Buy second hand then start searching for a place to fit & tune who won't rip you off

Qiksig you wouldnt be friends with a guy called Pete and womans name casey..
Just curious as if so i was wondering how to get in touch with them as they bought my mates turbo sigma from Bundy.. The Wigma was its name

NAr i broguth my sigma from a mate who got it in from a mitsu place in dandy.


It's a original turbo model..



So boys and girls wat computer can i use that will support a turbo'd magna?

TR that being..

And GTRICE wat is a ECM chip

greddy emanage, haltech interceptor and more, i'd just save till you can afford the wold 3d you wanted

monga does have bigger injectors, ive seen them and been there while its been worked on, so dont be surprised :P...the standard injectors run about 5-6 psi to my knowlege, the injectors you are after would be white TP injectors, they handle alot more, but make shure there white..

im goin for a supercharger setup and i have a megasquirt ecu lined up...they are being used on boosted e30 BMW's and they are diy for ppl on a budjet...they set you bak from $80 - $400 for a completed one...but i havnt heard about them here in aus much...mines comming direct from america....http://www.megasquirt.info/

Yea i was looking into the cheaper computers today and the megasquirt looks like a pritty simple setup for a simple car..


On the web sight it has a big diagram of the ECU and all the wiring and i was wondering wat the ICA and the ignition modual was??


Cheers

I'm running 10psi with aftermarket injectors + ems
stock ones are fine for about 2psi without damaging your car obviously you can exceed that but don't expect to last long

Wat injectors are u using??

and was is a Ems?



cheers

i am using a wolf 3d v3 engine management system with Toyota 1G-GZE Injectors
wolf is great and the injectors are 450cc my car can hook upto the laptop while im cruising and everything is displayed on graphs ect.

Thats alsome..

How much did u pay for ur wolf?


im going to use a mega-squirt computer untill i have enuff for a wolf.. :D :D

are you using a sigma turbo on a tr 4g54??? im bout to turbo my tr im thinking of a garret to4 or t28 but would love a sigma turbo but cant find one really.

tell u the truth i have never been bothered to sus out wat engine i have.. it's a 2.6 liter if that helps.. lol :bowrofl:



but i think it's a 4G54. correct me if im wrong.. lol

by somthing rear wheel drive. then u can have some good fun..Then turbo that babi..



Yea man.. trading post or ebay.. They usally have a few wiggy's in there..


Good luck any way dude..

Is that a type of magna engine??

my turbo spec

if its a original turbo sigma The compliance tag should have the following
"GH7X41xxxxxxxx123 the last three numbers denotes what build number it is.

i would be interested to know what number it is, as there was only 500 hundred made also the turbo sigma only came out with the 2L motor... as reading your post you say you are fuel injecting a sigma with a tr injecting system, are you doing it yourself if so do you have the digrams for the tr ecu pinout and fuel management digrams as i am putting a turbo on a TR for someone

anyways good luck sigma turbo's are good fun

Hey mate mine is build number 139.. Yea it was a 2 liter but now it's a 2.6.. Im trying to get it injected. Im going to be using all the stuff from a TR. I have a astron 2 head from a magna. So the inlet will bolt up fine.. Other then the manifold has 2 be changed.


If i can use the ECU from a TR for a while it would be alsome.... im happy to change the injectors..

that’s great my son's sigma is 407

i am sure you can use the TR ecu because they have a knock sensor that retards the timing. also the TR injectors should be fine i have a sigma turbo on my TN, it has the original TN injectors..
i installed a extra injector into the throttle body and i don’t see any diff at all,, except black smoke when the turbo spools to 3 pounds and it switches on the injector. so i can safely say the TN is ok using the original injectors.. so if i don't get a reply from here soon about ecu pinouts or em diagrams, i will go ahead and turbo the tr with the tr ECU and will let you know the outcome

Hey man ur really handy.. lol U got an email i need to chat some more about using the stock computer and injecting my car..

Cheers scotty

also the TR injectors should be fine i have a sigma turbo on my TN, it has the original TN injectors..

Actually the TN/P injectors allow more fuel in than those in the TR. I think from memory the 1st gens had a higher flow rate.

To the original poster, dont forget that you will probably need to cut the end of the plenum chamber off and have them welded on opposite ends as the air intake is on the wrong end, also there might be a big of a pain getting coolant into the manifold (because it is on the end that will be facing your firewall).

Good luck with the project and have fun.

Yea i have will look into the coolent thing.. i haven't yet got a manfiold.. But there will be away around it..



So some say that the ECU will work.. And some say it wont!

Do we have a decider boys??

IF we do tell me wat ECU and wireing loom to by and i will be there..

that is correct about the welding of the plenum and how the coolant runs... i have helped a mate put TN fuel injection on his GK GSR. Only trouble we are having is getting the heater to work, it doesn't heat up like it used to.

if you are putting a TR head on your block, check to see if coolant channels and oil galleries line up. between a 4g54b (aka Astron II 2.6 <-- unleaded) block and a TN head (M3 head) , one water channel does not line up, it's near the timing chain... the head gasket seals it off.

as for your ECU, well the stocko TR ecu will run the car, but your best option is to get a replacement one.

With the tr EFI gear, they had a knock sensor, but it is in the block (from what i gather - disreguard this if it's not) - meaning you will not be able to make use for it, unless your sigma block has provisioning for the sensor.

another thing you may wanna consider is TR/TS (M7 or later) heads had roller rockers... i'm not sure how well they go to putting other profile cams in. with TM/TN/TP heads, sigma rocker gear can be put on, and this will allow you to adjust the rockers no matter how lumpy that cam is. (stock ECU wont take kindly to different profile cams).

you need to take your car down to an exhaust place and get the O2 sensor put in. we bought a nut of the right thread and asked the dude at the exhaust place to weld it on. the thread on the O2 sensor is M18 x 1.5

I am going to put TN EFI on the Triton one of these days and when I was looking into this I discovered this problem. How did you route coolant in via the thermostat?

Exactly. Most 1st gens dont even have provision for it!

Actually M6 heads have them too with the kidney shape combustion chambers. The problem one would have here is the increase in compression - too much compression isnt a great thing with a turbo.

Very nice.. so the injectors will be ok!



wat about all the sencers?? will they allow 4 some boosT??

what was the verdict about the Megasquirt ecu because ive got a tm with tr efi gear on and the ecu has died so looking at aftermarket

1. OP hasnt been online since mid 2006!
2. everything has moved a long way since the posts in this thread were made (2005!)

firstly you are using the TR ecu in your car currently? has it run since you put that in? if not then you've probably accidentally chosen a donor car that had an immobiliser fitted. it was an option on all second gens we (me and my mate chris) think.
if this is the case then youd need the key and all that to statr the car. are you getting no pulse to the injectors?
how did you diagnose the blown ecu?

it has been running but never normal coulent get the idel to drop with out laging, and went through the gerogried manuals and workshop manual testing all the components that it said it had errors with and they all passed and every one of them came to the last step of replace ecu. so im getting rid of all the factory ecu shit and putting megasquirt system in. yer i think it was a dodogy donor car
