Summer of set-backs finally progess

[Raph]

Are you gonna change the spring on the waste gate so u can run less boost? 11psi on hte stock block spells nothing but "T-R-O-U-B-L-E"

Your status on this site will go from

99 eclipse NT......
99 eclipse NT (w/turbo)......
99 eclipse NT (w/turbo).....(w/out motor)

i dont think so..

i have a 2g nt ,now its turboed ( mind you it was a germanspec car with a 4g63 nt..but thats not my point) i started with 6psi and stock injectors and a fmu ,then got a wideband aqnd a safc, upped mz boost to 8psi..

then i got larger 460cc injectors of a rx7 ,im now running 13 psi safely with 11.4 afrs at WOT ..spiking to 15 psi for some strange reason.

oh yeah,im using 93 octane.

i did think i was going top blow it up, but i listened to my buddies ..and we upped the boost slowly..

im still on a stock HG and Clutch..no probs there whatsoever.

been running like this for 7000 kms

itll soon be winter,im going top switch blocks with one im rebuilding to handle some serious boost ,and i will tear done this one just to see what the 13psi of Abuse caused( if any) ..by Abuse..yes,this car has been beaten on WOT runs for miles and miles on the Autobahns.. 120 plus mph runs are normal.

My point is, its in the tuning with a wideband and safc.. its all you need..

but i must agree with on on running low boost first.. for a few weeks,then upping boost and fuel system to compensate..

oh,heres mz trick..i always upped the boost at home.and did test runs on mz street..in case something went boom ..i wouldnt have to tow it far

 

[Raph]

Where did you come across an actuator with that low of a spring? J'w...I should prob get my boost leak fixed first though..So I can find out what mine is set at..

Josh

i think turbospecialties have stuff like that..jus call em

you gotta be kidding me right

just like u said buddy, you've got a 4g63....PERIOD

whether it's the n/t or turbo model, it's a different motor all together. What BigRand was pointing out was the limits of the internals on the 420a

We know you're special with you 2gnt euro spec etc, but that doesn't automatically mean you know jack about our chrysler powered versions over here

They are tempermental and all. You could be running nice and tuned 8psi, decide to turn it up just to 10 pounds, and boom she'll blow on your first run. Then, there's others who bolted on a kit and have run 10psi on the stock block ever since. The point here is that you don't have the same motor as us, and for you to just jump in here is exactly like the other turbo model guys (not all of them) who post thinking they know everything about our car.

i didnt opst talking about knowing everything.. it justs interests me..the 420a

why, because i got a friend who has a neon, and its old and ive been trying to either get him to turbo it..or b..make him sell iot to me for real cheap so i can turbo it..sheesh.. dont get me wrong,im a nice guy..your acting all up..sorry if you took offense from my post

me and my friends like to turbo everthything..so i read alot of threads like these to see what others are doing,to share ideas and learn from others..

we are in the middle of a another Fiat turbo project as well as starting on a hyundai..just need to figure the map sensor stuff out..thats why im checking the 420a threads out..

Thanks Selmerguy

Xmasta19-You make a good point. When I first got the idea of boosting this car there were a lot of "uncertainties". Like when me and my mechanic first went into it, it was going to be a weekend project and that everything would go accordingly. The first problem I went into was my actuator not extending to the WG. Then we noticed that my manifold would make the DP very hard to make and that I will have to settle for a smaller DP because of less room from the radiator hose and AC lines. On top of that running a return line for 97+ was a PITA. I use a 4g63 fuel rail that was machined to my Intake manifold. It has the 1:1 FPR and the N/T DSM 360cc injectors. Which was ran back to the tank with a 255lph walbro. There is some sort of regulator in the back of the car that we by passed and capped off. This is my fault buying and XS power turbo, but the oil feed had some wierd ass tap size and no oil fitting we could find would work. As in the pic on the prev. page we used a DSM AN line brazed to a SS line. So my advice to anyone wanting to boost a 420a would be to get the star or hahn kit. I can't point the finger at anyone but myself for this but at the same time I haven't been driving the eclipse for 2 months plus now because of all these "setbacks" as in the title. So come Thursday when my DP will hopefully be made, I hope that I have no leeks, I run with good A/F ratios, and most of all I don't blow up. Conveniently the 5lb spring takes some ease of my back because I am not running high boost for a stock motor, at the same time anything is possible. So with that said I am going to keep the 5-7psi range until I get a better fuel management system (portfueler, megasquirt, etc.) So I would take the advise from people that have done it more than just an assumption. I am not doubting Raph's knowledge at all, its just that the fuel has to be right and limited boost pending internals and clutch.

Once again wish me luck with my "unique" setup and I will hopefully be able to post up on Thursday.

 

[XMasta19]

no problem man, good luck

...and don't worry, all of us who went the custom route have "unique" set-ups

Raph - Wasn't meaning to really bash and what not...just woke up and hadn't had breakfast yet Anywho, just cuz your buddy has a neon, doesn't automatically mean he has a 420a, just so ya know

 

[DSMcrazy3]

Goodluck!! I was so happy when I got mine running, it was still on jacks, with an open downpipe, and I couldn't hear the turbo over the DP(we were in a garage too, to make it worse haha) I revved expecting to see boost accumulate. When I didn't my heart dropped and I thought I had gone through all that for nothing. Then I said F it and went for a ride and heard the turbo spooling and man, I was in love! Anyone doing custom set up will go through some crap. It isn't easy, but when it's all done it's nice to know you're the only one with it the way you have it I hope many people that want to turbo read this so they will know when trouble comes, not to give up and that it isn't THAT hard to do, just follow instructions.

Josh

 

[greenmeanie99]

Yeah hopefully I will be able to enjoy it in 48hrs. In the mean time I have to worry about getting it to the exhaust shop on the tow truck . But yeah as said by DSMcrazy3 there are lots of troubles in custom work and I KNOW, it will be worth it DSM4L

 

[greenmeanie99]

Also with the setup listed and in the profile does anyone think I can break over 200whp with 7psi?

 

[BigRand]

Well you'll be close, but it all depends on tuning, and what time in the morning you do a dyno pull, and what gear, etc. But it will be real close.

To give you a hint, I had the same setup excluding all the return line stuff (which I have now), and used a SAFC2 to tune with 370cc injectors.

Anyways here was my result after about 2hours. I was at 193whp but my real big surprise (for me at least) was my torque numbers 222ft-lbs.

Good luck.

Oh yeah, I think I was at 7.5psi

 

[greenmeanie99]

I see. Yeah I have an S-AFC and 360cc's. So we are pretty close. So I hope to get some good power out of this. It WILL be dyno tuned down the road but for now Ill be going off the AFC and the gauges. I really want a wide band o2.

the widebands are nice. beware of the innovate wideband i just bought the lc-1 with the wd-1 gauge. it says it has a input and i assumed that meant for rpm, egt ect... when it got here i found out that i have to buy another piece called a lma-3 to have all the nice logging stuff. and they don't expect the software to be out for another month to log with out the lm-1 controller.

 

[greenmeanie99]

So Im taking the car to the exhaust shop to night for the finishing touch.

Im hoping for a 2.5'' dp but I don't know what is going to fit. The guy Im' taking it to has over 20yrs in custom fabrication. So Im hoping he can do 2.5 or bigger

should't have a problem with 2.5", STAR kits come with a 2.75" dp, with the t3/t4ob(e), I guess it depends on how well you had your mainfold built.

 

[greenmeanie99]

yeah there isn't much room to work with unfortunately. Put it this way mandrel bent I can definately get 2.5'' but I'm not sure about 2.75'' or 3'' WTF

 

[BigRand]

3" is definatly a no no, without losing your AC, just see if they can't get a 2.75".

 

[greenmeanie99]

more pics of the setup.

Also check out the clearance I have for the DP

 

[DSMcrazy3]

Loosen the clamps on your upper radiator hose and turn it counter clock wise so that the curve will be up higher. It will give you alittle more clearance.

Make sure you don't turn it so much it goes on the radiator at an angle, make sure you can get a good seal from clamping, without tearing it

no hard feelings

actually , its a 2 door modell, a 2.0 with 135 bhp..so im hoping its a 420a

 

[Raph]

the widebands are nice. beware of the innovate wideband i just bought the lc-1 with the wd-1 gauge. it says it has a input and i assumed that meant for rpm, egt ect... when it got here i found out that i have to buy another piece called a lma-3 to have all the nice logging stuff. and they don't expect the software to be out for another month to log with out the lm-1 controller.

i wish id taken that route..the innovate lm1..beware of the zeitronix(my fault..i wanted to save 50 bucks ..unstable logging software and lcds that go broken before your even started..still waiting on a new one.

 

[DSMcrazy3]

A buddy of mine had a 2 dr. neon, it was in fact a 420A, just single cam.

 

[BigRand]

A buddy of mine had a 2 dr. neon, it was in fact a 420A, just single cam.

Just so we are clear, your saying there are two types of 420a motors? SOCH, and DOCH?

SOCH being rated at 135bhp (for the 2dr neon)

DOCH being rated at 140bhp (for the 2g eclipse)

DOCH being rated at 150hp (for the regular neons we are used too, 4dr I'm assuming)

Just wanted to clear the air so we all know what 420's are out there. Is that list correct?

 

[greenmeanie99]

Yeah list is ok I researched.

Here are the pics I meant to post last night.

 

[greenmeanie99]

Just a quick question. I have seen that people use a greddy harness for the TT's. Will the gst/gsx harness fit a gs? I saw another post similar but it said use the greddy "GS" harness.
