Well there ya go

 

Haha there not old beat up motor there is something wrong witht he fuel injection that i need to find out what it is, the motor that i just put in and blew was in perfect shape.

The plain right now is

Heavily streetported S4 NA, maybe a S5 NA
Having Turbo rebuilt with a 60-1 cold side
Rtek 1.7 ecu
Water Methanol injection
Custom Tubalur Turbo Manifold
plus much more

I was before doing roughly about 250-275 rwhp and i plain to hit somewhere close to 350-400 on the new setup.

 

thats real scary seeing that it doesnt get fuel for that split second and kablooy!!still determined its the fuel pump?

 

what I want to know is if you have an STI, then why are you putting money into the old beater car?

(of course, I might be mislead by the abundance of cheap aftermarket knock-offs for posers)

 

no i' don't believe its fuel pump i'm sure its the secondary fuel injector on the front rotor.

I have a 2000 Subaru Impreza 2.5rs with complete upgraded suspension work and many more mods, but the RX-7 its still funner and faster.

 

I went past the 3500 mark one time and that was the last time before the motor started doing its "me don't want to idle thing"

 

thats real scary considering this is what im doing but using the spacer method.oh well, if it blows, its porting timeoh yeah, stock s4 turbo runnin about 10 psi with fd fuel pump,safcII,wideband550's,720's,and custom fmic!this is what im doing in 2 weeks, finally!

 

My project I purchased last year is a'89 GTU 13B, 6 port, locked motor, pristine body, $500. Purchased new exaust ported rotor housings, & rebuild kit. Then bud hooks me '91 Turbo II that runs. I already know I can use the rotor housings to rebuild the Turbo II. I have been very curious about the high compression rotors being used in a turbo engine and the good or bad of combining with the 6 port.

 

make sure you get your hands on a TII ecu and what ever else you need to use it

 

^ shouldnt i be ok with the stock ecu? i thought alot of people ran there stock ecu?

 

he is running my old s4 tii ecu... it solved alot of problems.

 

You might be fine for very low boost, i had a lot of issue of leaning out up top above 5k with the na ecu, like 14 afrs

 

Oh also if things go right i will be putting in a heavily street port S4 NA engine in

 

what kinda low boost are you talking about? and what boost where you hitting when you were leaning out?thanks.

 

i was running 10 psi on the na ecu, not sure what the highest boost you could run on the na ecu

 

Yeah, ditch the N/A ecu as fast as possible.

 

damn it! this sucks!so that means i need the knock sensor wired in blah,blah and the rest of the stuff? not to mention the rewire!

 

**** any stock ecu, go megasquirt, i will once i find someone in my area compitent enough to tune it.

 

^heh, id love to if there was anyone near me that new what thet were doing with one. id love to go haltech.

is this what i need to do minus the tII motor? what about the sensors on the motor side? will everything be ok on that side? do you prefer the knock box?whatelse?

 

i just want our fuel back at the pumps! AAAAHHHHHHHHHHHHH!!!!!!

 

Do you have any experience at all with the 'Squirt, or are you just repeating? Because if you are just repeating, please stop it. Like ANY standalone, installing the Megasquirt is not for the beginner as a wiring harness must be made, appropriate connectors used, proper fusing, etc. And of course there's the tuning, which is not a small part of the whole thing.

 

This kind of project in general isn't for a beginner (though they all try to act cool and do it anyway)

 

7 degrees advanced at idle? 5 degrees stock? do you mean 7 and btdc? it is suppose to be 5 AFTER top dead center, so 5 degrees retarded...

 

well we all learn from mistakes right? if it blows all well at least i died trying.thats why im asking all these questions and tring to take in as much info as possible to prevent and learn. so what all do i need if i use the tII ecu? is this gonna need a fcd now if i use one?could someone just make a list of what ill need to make it work? and how will the ecu react to the 720"s?

 

i second that. here's another question - i'm also gonna use the tii manifold set-up to turbo my n/a. i see you guys are using another way of feeding coolant cuz the n/a housing doesnt have the hole that the tii lower manifold uses; has anyone here thought about jus drilling a hole through the housing to get the coolant? i just took apart a 6-port and to me it seems like you can. any thoughts or concerns?
