Need some input on my EJ207

SoobyStu · 02-17-2005, 07:37 PM

Well i have finally got my Ver7 sti engine in and i was thinking i might as well wait a little bit for the dyno. I'll just keep putting in 101 octane fuel in for now instead of 2 trips to the Dyno as i have plans for a bigger turbo. I plan on taking it to crawfordperformannce/i-speed to get it done

'I'm looking at getting in to the Low 12's high 11's with this motor. I know that a bigger turbo, injectors, and fuel rails are needed. Money is an issue as it always is when modding. I have heard that the FPgreen does preety good.

I live in California so maybe this can be achieved on 91 octane maybe it cant. Also The injectors, i have seen a mod posted by kingpin where you take the end cap off and the flow rate is about 750-800 cc . Anyone done this? is that a sufficient amount of fuel with the green to get into those times?

I have the JDM tranny,stronger clutch, and a huge top mount, so i think all i'm looking at are the things covered above.

Also what WHP should i be able to achieve with this setup?

Thanks Stuart

somewhere between 375-425 depending on tune, dyno, and injector sizes. i would say a gt-30r is a better selection.

ebeck · 02-17-2005, 07:43 PM

A Green on race fuel will most definitly get you there. I use PE650 injectors. In California, the gas is real bad. A good tune is real hard to get as the poor gas just plain prevents you from making power. Detonation sets in real easy. We have the same problem in AZ.

On race fuel expect the 400whp mark with a proper tune. Proven Power forum is filled with Ver7/Greens.

Good Luck.

SoobyStu · 02-17-2005, 07:53 PM

is the GT30-r direct bolt on?

ebeck · 02-17-2005, 08:55 PM

Depends on which one.

SoobyStu · 02-17-2005, 10:04 PM

I just checked out the kit gruppe-s are getting together. The only thing thats putting me of on the GT-30 is the loudness of the wastegate venting and it looks a bit laggy although maybe not so bad with avcs.

ebeck · 02-17-2005, 10:12 PM

AVCS is everything. J207 is in no way similar to EJ205. What applies to one does not apply to the other.

SoobyStu · 02-17-2005, 11:03 PM

ebeck what setup do you have on yours?

I'm not so sure about this... From what I've read, avcs is like a stock WRX at low RPMS but then changes to advance timing at higher rpms for more power. AVCS isn't something that helps out low end, it helps keep the low end while having the a better top end.

I may be wrong, but that's what I remember.

SoobyStu · 02-17-2005, 11:30 PM

interesting

ebeck · 02-18-2005, 12:12 PM

Shut off the AVCS and the dyno plots look like a USDM. Pretty much identical. no power, no power, no power bang boost. More power up top obviously it is JDM. Turn on AVCS and you make alot more power down low and the turbo tends to start spooling sooner making power where there was none with out AVCS.

There is some good info on AVCS out here. AVCS stops at 6000 rpm or so although you can control it with ECU-Tek. It functions from about 1000-6000 rpm if I remember correctly.

pegdrgr posted this AVCS on and off dyno comparison. Peak torque is 1200 rpm sooner with AVCS and is more dramatic. http://forums.nasioc.com/forums/show...highlight=AVCS

The effect is much more pronounced on ther Ver8 motor which I have. I did the same tests on the dyno.

this assumption is incorrect. the compression is higher in the V7 and does give some gain and slightly quicker spool when compareing identical setups to a ej205. Of course you want AVCS as that is great feature to have to add to your powerband, it is a selling point along with the forged internals.

as you have experienced, it is more pronounced in a v8 motor

ebeck · 02-18-2005, 12:48 PM

1) Did you pegdrgr post of the Ver7 RA motor? I put the link above. That is not slight. Also that was with a Green. With a smaller turbo like a VF34 or so, it becomes more pronounced.
2) The Compresion is not higher on a Ver7.
3) No it is not.
4) Nooooooo it is not.

fastnoypi · 02-18-2005, 01:07 PM

ebeck, now you are making me think i put a serious hurting on my ej205 to explain some hp, spool, etc.. blowby losses

per my experinence back to back with my old stock tmic setup with the 1820, the v7 with and without AVCS was noticably different that the EJ205 on pump 93

maybe im missing something here and i need lunch, but the link shows differences on the same jdm motor w/wo avcs on. Im comparing the ej205 and ej207.

ebeck · 02-18-2005, 01:11 PM

Right! Hey, you getting KingPin GT3040 man? Thought I heard that somewhere. That is a MAN size kit!

First things first...need to get a JDM 6sp. I dont want to look at a transmission jigsaw puzzle on the 101 anytime soon

ebeck · 02-18-2005, 01:16 PM

Ahhh yes. Good plan! Wait till you feel the difference with that GB. astonishing.

Sorry to Hijack. Back on topic.

SoobyStu · 02-18-2005, 05:28 PM

Nice car ebeck, 320 whp with the green. I was hoping to get around 350whp with my setup with the green on pump gas. Could you recomend some Engine managment so i could get tuned for 93 and 101 and change maps when called upon. What type of numbers could i be getting with 101

ebeck · 02-18-2005, 05:54 PM

Actually I produce 332whp with an AVO450 a TMIC running 91 octane tuned by Kingpin. Ver8 Magic! My car with C16 WILL go over 400. I would expect 280 with 100 octane on my car.

Utec and Ecu-Tec seem to the the top choices for EM. Personally I like Ecu-Tek. For straight racing purposes I would do Utec. It seems to ber better as you do not have to fight the ECU.

You can have the external WG plumbed backin to by the way. also it is only loud when it opens. Run an 18# spring. That way it wil only open if you are serious. At that point, who cares about noise.

SoobyStu · 02-18-2005, 06:30 PM

What about XEDE is that a good choice?

XEDE is typically not used on JDM swaps because there are no passthrough on pinout for AVCS. Utec 6 and above have that feature.
Hydra is very close to being a choice EM for AVCS, but from talking to owners that have tested it, it is not quite mature yet for the AVCS controlability.
Alfriedesq had very good results with an A/F controller (SAFC), any other one work too (HKS-SAFR), etc.. but limited to stock on board timing.
For now, leaving it set by factory and using Utec are choice for JDM swaps because of the flexibility IMO.

ebeck · 02-18-2005, 07:09 PM

Vishnu? As far as I know it is a plug in or piggy back component. I was not aware that is was a programmable engine managment component. With ECU-Tek for example you have complete control of AVCS etc.. The ENTIRE ecu function is programmable. Not just air/fuel/boost. Changing boost is not managment.

Go Ecu-Tek. You can run Delta Dash as well. http://www.ecutek.com/

SoobyStu · 02-18-2005, 10:01 PM

sorry to go off the subject but i just got done with the motor install and the cars seems to be revving aratically. I'ts not the cruise control nor the accellerator cable. Any ideas?

revving between 1500 and 2000 up and down pulsating??????
