Update, head/turbo FS (long..)

This could get long. :D And there is a for sale at the end, you've been warned :p

Car is back and running again. All of the little bugs seem to be worked out, except for a small boost leak at the TB or TB elbow area. DSMlink V2 is badass, many new features. Antilag is nuts. The BJs manifold looks great, and all of the vac fittings are very neat and reliable looking. I'll post a pic later. The 950s are in and tuned somewhat, but my trims are still way off. The tial 38mm holds right at its spring pressure of 20 psi, so I can theoretically go to 40 psi now. No more 25 max psi excuse this year ;) The new motor seems to be breaking in nicely, its getting faster each day. I should check the compression today to see what its up to. I did some mild porting on this head, and the rebuild seems to be good. I've had problems with one shop, I went through 3 heads that all smoked almost right away. This one was done at a great head shop that is 10 minutes from my house. So far so good. :)

So, seat of the pants is pretty good now that the new motor is breaking in. In got on it in first today from a roll, and the turbo spooled quick. Hit the tires hard enough to send the car sideways ass end out at about 6k rpm. For data, all that looks promising too. I seem to have found the limits of the airflow graph in DSMlink, lol. At 60 lbs/min I seem to be off the screen. I'll have to ask them what I can do about that. I dont think the Y scaling is user definable. It doesnt feel like 60 lbs/min of power though, so it still needs some time to get up to par, and needs some more tuning. Its at 10.1:1 or so (rich). But for 20 psi, its at least as fast as it was before at 25 psi. Cant wait to get the prfec hooked up and lay into it.

I plan to hit the dyno soon. I was waiting for a friend to get his car done so we could dyno mid feb. But my car taking so long has now delayed the start of work on his car. So I may just go in a couple weeks. We'll see. Either way I'd like to dyno by the end of the month. That leaves a month still in the offseason to work out any issues I may find.

Which brings me to my next point. I plan to sell this turbo. Part of the reason I am going to dyno is to see what it can do before I sell it. I'm expecting 500 whp from it. Its rated to 65 lbs/min and i'm damn near that already. Imagine with race gas and more boost... I'd like something in the 75 lb range for the new setup to make sure I dont have it maxed out all the time. Antilag in V2 will help me spool a large turbo anyway. So if anyone is interested, I plan to sell the "M14" after proving its worth at ~500whp, along with the custom manifold (old FP built 2g with deltagate off all 4 runners), Deltagate, dumptube, and TRE ported O2 housing. I Can sell just the turbo, or the whole kit. But I want to at least keep the manifold/WG/dumptube, and perhaps the O2 housing, all together. Its all a bolt on affair for 1g or 2g. The manifold has a crack in the weld at the WG, which I may or may not fix. The turbo doesnt need a rebuild, but I can have that done for an extra 150 or so. It spooled at 4400 rpm for 25 psi on a 2 liter. I would like to see at least 800 for just the turbo, or 1200 for the whole package. Its not for the casual modder, but there are several people on here that could handle this, or grow into it. For the right buyer, naturally I would help with any questions that arise about how to set it up, or tune with it, etc. For whiny mommas boy buyers, youre on your own :p

I also have a 1g head fully rebuilt, well ported (exhaust side polished), all new bronze guides, 1mm over nitrided valves on both sides, with a competition valve job. Its basically a stage 6 SBR head, but I dont include springs/retainers. I have 1000 in it, and thats all I ask for it. I have a 2g head Im working on as well if anyone is interested. I dont need either of these anymore. Both were/will be done by the same guy that did my current head. He's done about 6 for us.

I dont like to advertise on here, but I thought I would give you guys a shot at this stuff before I put it on the national lists.

Cant wait to here what your dino run tells you. i am glad to here that you got the POS back together and performing. now if i wasnt in college i woud have a new turbo. damn schooling makes you poor for so long. looking forward to hearing updates on your car. :thumbsup:

holy shit dude! 75lbs/min thats nuts!! damn, well i am glad to hear its running good, got one question for ya, you said somthing about the baro wire mod for the 6 bolt swap, how much was that and what does it do / how do you hook it up? i was looking on MMS.com and i didnt see it but i will also check again... and if its somthing you buy, do you still have yours, i would be willing to buy it from you! i plan to put DSMlink in it by summer but i dont want to have the misfires until then so anything that will help! thanks~

Buy a 5k potentiomenter at radio hack, about 1 dollar. Put it on the baro signal wire (see the vfaq ECU pin out for what wire/pin it is off the ECU) using one "side" pin and the center or "wiper" pin. Set it for about 1000 ohms across those pins. You want it as low as you can set it and not get random misfire CELs, and no higher than it needs to be. Be prepared to adjust the AFC positive by about 30%. Use the datalogger to make sure you have properly compensated for it. ;) When you get DSMlink, just turn the knob all the way down to 0 ohms (this could be all the way to the right, depending on how you did it, so be careful) or take it out and reconnect those wires. Check the box to disable misfire detection in the DTCs box. No fuel compensation required.

See why DSMlink is so attractive when you have a 6 bolt swap :)

damn i guess so... ok do they explain that in detail on VFAQ or is there another site with pics :icon16: thanks for your help man!

No pics. I guess poeple figure if you can do a 6 bolt swap, 3 minutes worth of wiring shouldnt be too bad. :D Check the 1gina2g yahoo group, someone there may have done a vfaq or something.

oh i know i could do it without pictures but you know they are so much nicer!!! i was just being lazy <--- what else is new! well thanks.

Sweet! I was looking forward to this post for a while now. I have around 40 turbos on my list, and none of them can flow 75lbs, what are your choices in that range?

EDIT>> There are people in the 9's on less than 75lb turbos correct? FP3065 obviously, I don't know if a GT35R hits 75 or not, but are you saying you will have 10lb/100hp more than Curt Brown this year? (FP3065)

The 3065 and GT35R both share the 56 trim GT30/40 hybrid compressor wheel, rated at 65 lbs/min. The same wheel is in my current turbo, the one for sale. The thing to remember is that curt and those guys run very lean, massive timing (they actually dremel out the slots in the CAS so they can advance base timing even further), and push coolant on every pass (from the head lifting). The cars are also very light, and they drive like madmen :D I have a video of shep wrapping his 35 psi boost guage to the pin. I noticed in a newer vid he has a 50 psi blower guage.

In my fat ass 2g daily driver, I need to run richer, less timing, and less agressive in general. So I need more turbo to get the job done. If I had a gutted 1g my current turbo would be a whole new ballgame...

I was looking at a used AGP setup, with a T66 comp wheel (72 lbs) and a P trim t4 turbine wheel but it was sold. But thats the range of turbo I'm looking at. FP and AGP agree that a GT35r wouldnt even be an upgrade for me. So I have no choice but to go bigger. Thank God for DSMlink's antilag ;)
