Hey Clark how about that Axis 2.3x liter?? I remember you or Dave (cronic) saying that was an amazing motor as well. How did that run?

But from what I've been seeing is around the country they are doing OBDII tests only on 1996 and newer cars. Some places if it fails the OBDII test they will tail pipe test it but in Illinois your only option on a 96 and newer car is OBDII test you fail that and you have to fix it till there are no stored codes. Even if the code is something stupid like a tranny code which has no effect on emissions output.
It all depends on the state. Some states testing machines cannot read the JDM ECU. When I was in RI their machines were able to read my ecu and it was fine. When I moved to CT the testing machines could not read my ECU at all. So they did a sniffer. I passed the sniffer test catless(just barely iwas like 217/220, only 3 points from failing). If you can do a tailpipe test it will actually be easier for you to pass than an OBDII test.

now I'm very curious if the ones in Illinois can read the JDM ECU or not. sinc I've been pondering putting a 207 in my car once I get it paid off. OR I'll just have to move to a different part of Illinois that doesn't do emissions

Same here. The CT equipment cannot sync to the JDM ECU. I passed the sniff test with flying colors, though I do still have a dp cat. At least CT is willing to do a sniff test on non-compliant ECUs - I've heard some states will automatically fail you.

strange..in early 03 i passed inspection in stamford,ct with a single cat on my EJ207conversion...since then im not sure if they got any more strict...very possible but it seemed strict back then with a tail pipe sniffer while on their 40mph dyno if i recall

Those motors where 2.2 legacy blocks which are closed deck with the 2.5 crank. They ran much smoother. Those blocks are hard to find now. Crawford built one for a friend of mine a while back. It piston slaps in one cyl since day one. But its been running strong for over year of abuse making 500+whp on a Mustang dyno. I recently tuned it to 36 psi with a GT35R. It laughed at that.

bring this back from the dead.

I recently did a V7 EJ207 swap and i love the smoothness as everyone states.

my question is if I should install the VF22 that's just sitting and have it tuned or get something else more fun. I live in an area that you cannot really get on it as much and I do auto-x. since this is a standard V7 it has a VF30 installed already.

what are my choices and why? Street ability and smoothness is a requirement for the type of tuning i choose and what EM should I use? I'm currently using a JDM V7 ECU ATM with AVCS working nicely

Thanks,

Jon

I don't think there is much difference between the vf30 and the vf22. I put a td06h-20g on my motor and I love the response. I haven't had a chance to fully tune it, but the response on the street feels very similar to my evoIII 16g on my ej205.

As far as EM goes, I think you'll have to use EcuTek, OpenECU or a UTEC (or a combination of them).

thanks for the response.

where'd you get the TD06H-20G from and how much was it? Did you internal or external wastegate your setup? What EM are you using?

Please define response. When does the turbo start spooling and when do you get full boost? does it taper off towards 8250?

I auto-x the car so I need the power on the low side you know?

Thanks,

Jon

- I've looked into Enginuity but don't know where to start. In actually tuning

Where are you guys getting your motors?

I plan on selling my wrx soon and i plan on buying a full v7 swap (motor, tranny, brakes etc...) for my 95 L coupe. should i just throw on a 20g, keep the v7 i/c, bigger injectors, tbe fuel pump and enjoy it?

if you want power down on the low side, you might love the Evo3 16g for a wide powerband. congrats on the v7 swap!

it's been a long time coming for the swap.. I had the trans for a while just didn't have money for the engine. I pretty much have built my a jdm sti v7. the only thing left is the RHD which i won't do and the V7 seats. everything is JDM platform.

EVO3 16G? kinda n00bish at turbos. i've only owned TD04 from EJ205 and VF30 on the EJ205 and the JDM VF30 that came on this engine.

I'm also thinking about putting on a twinscroll vf37 or vf38 kit and running jdm v8 ecu. I'd love the low end power but want to be able to still show my car isn't a normal WRX badged as an STI you know?

at this moment it isn't an WRX anymore but the VIN still says it is

isn't the 16G trim similar to like a VF30? I know MHI is completely more reliable and better turbos than IHI ones

I have been wondering the same thing but the other problem is how much they are cracking down on modified cars in socal. So I want a setup that wont get me into to much trouble if they suddenly get the itch to start looking.

THere is no point at all to go to a VF22. Leave the V7 engine alone. Just have it tuned by someone that knows these engines.There is alot of power in the tune on them.

well the problem with that is that I live in Hawaii and I'm the ONLY one that has an engine like this. There are NO tuners available and we have to get someone from the mainland to come down and tune for us. The VF30 that is on the engine right now has a small crack in the wastegate area (the usual) and I need to have something more reliable as far as a turbo is concerned. I want to be able to have the HP/TQ that I need when at the track and be able to boost it once in a while and make me forget about all the stupid money that I've thrown at this car.

You are right the V7 is a great engine... NO complaints at all.

I did install a APS turbo inlet though in preparation for a bigger turbo in the near future

If the VF30 is cracked then go ahead and put a new VF34 on it. Its the spec C turbo that should be on it. It is a better turbo. VF22 would also work as a replacement but will come on a bit later. You need a remap already because of the turbo inlet. Do you have a way to datalog the car so I can look at the logs?

well i really don't want to spend money on a housing that will crack again you know? it doesn't make sense.

Anyway...

AZScoobie... I'm not entirely sure how but I believe that there might be a data logger in Enginuity. What data do you need and how do i drive the car when logging?

Will I need tune for the 34 or will it be a direct replacement. I'm really looking for something other than a VF series turbo though

what are the main differences between v7 and v8 and do they make a big enough of a difference to justify getting the v8 over the v7?

I think you may just have a bum housing. I haven't heard of many IHI housings cracking except for the VF39. You could potentially throw the P20 housing off of you vf22 on the vf30.

The evo3 16g is a bigger version of the 16g turbo. It should flow almost as much as an 18g but with better lowend response. I had one on my ej205 and loved it. The only reason I changed that setup was because I broke my transmission and got a good deal on an RA gearbox and v7 motor. My motor also had 70k miles on it and swapping in a motor with 30k miles seemed like a good idea.

With the RA second gear, I'm getting full boost (~20psi) by 4500 and it holds out until redline. Engine load does taper- I'm not sure why. I have to investigate a bit. It could be cams, the TMIC- I can't see how that turbo is too small, but I'll get some post IC temp measurements and see what's happening. I can tell you that with a base tune @ 20 PSI, I'm already hitting 300 g/sec. I can't wait until the meth gets turned on.

If you want to have a lowend monster, I say put the vf22 hotside on the vf30 and call it a day. If you really want another turbo, the evo3 16g (or super 16g) might be fun. I bought my turbo from Jerry @ Deadbolt (boostplanet.com). He can pretty much build you anything you want, so you might want to ask his opinion as well. I like the MHI turbos because they really start to shine with more boost and the v7 motor should take boost nicely. I would also recommend the 8cm hotside over the 7cm hotside, especially with the higher rev limit of this motor.

As far as logging, enginuity does have a datalogger. I could log the following:
ignition timing
knock correction
AFR (wideband if you have one)
Manifold Absolute Pressure
AVCS
Engine Load
MAF Airflow Voltage
Primary Wastegate Duty Cycle

Try doing a pull in second or third gear and see how things look.

thanks mike I really appreciate you and the others helping me with this.

This is my second VF30 that has cracked and others that I've heard of experience the same thing. deadbolt also confirmed the same thing as well.

What about the FP EVO3 18G? Over kill?

I currently am using a JDM V7 TMIC but will be using my APS DR500 FMIC after I get it recoated.

I'm not really chasing a number for WHP as apposed to having a smooth tune and smooth HP/TQ curve of this engine. It would be nice to put down some high numbers but HP doesn't always mean street ability though.

I don't have a WB02 yet and I plan on getting that shortly.

I'll do what I can and post up. Should I use external or internal wastegate setup? I know that I'll have to tune for the EWG but preciseness is always a plus in my book.

Jon

i'll see what I can do as far as a 2nd and 3rd gear pull to redline.

as far as I know and I'm sure I'll be corrected on this but the V8's were the first year that they introduced the twinscroll setup being the VF37 is for the standard STI and the VF36 is for the Spec-C (titanium shaft and more goodies) from what I further understand these turbos spool at least 500RPM faster than a 34 would. They do NOT make as much top end HP but the TQ is amazing.

STI V7 came with both small port and big ports depending on the heads that came with them. V8's all have big ports.

I believe they are the same internally other than the things mentioned above.

I would love to eventually get a twinscroll setup but that's after I play a little

i'll see what I can do as far as a 2nd and 3rd gear pull to redline.
I'm running a 20g and like it a lot, so I don't think an 18g would be overkill at all. You have a choice between exhaust wheels on the 18g, I've seen them both with the td05 and td06 wheels. I think the 05 will sacrifice some topend but give you some more lowend response. I don't have any experience with the 18g directly, though, so I am speculating.

I'm running a USDM STi TMIC. I need to get some temp measurements to see if it's holding up. If you want to keep response, you might want to try and stick with the TMIC instead of the FMIC. If you look on pltek.net, they offer a service where they recore your TMIC with a Griffin aftermarket core. I can tell you there is a lot less pressure drop on that core and it seems to work really well as far as cooling goes. I've yet to try one on my car, so I can't give you any hard data, but from the people I've talked to, they all like them a lot.

An EWG will make more power at the expense of cost and/or noise. It's really your call. I like stealth so an EWG doesn't work well for me, unless it was piped back in, which as I understand it, starts to diminish the benefits or having the EWG in the first place.

I think either the evo3 16g or the 18g will make you happy- I'll try to get some third gear logs tonight to show you how the power band looks for a larger turbo. I've got a while to go to get everything inline, but it's starting to take shape.....

Hope that helps.

Mike
