So I'm gonna be Boosted soon!

[Goodspeed]

Deal with it. Boosting your car can bring a myriad of issues that you need to address. Its a slippery slope.

Lol....do you have 1500 dollars to loan him for a fuel system so he can "deal with it" ??

Ryan you can always install a meth / h20 injection system to help keep your IDCs down. You may even be able to run a little more boost than what you were anticipating. Just a thought, it's like maybe $800 bucks and you could probably install it yourself.

Meth...you bring up a good point. If Ryan and I got together and got into "meth" maybe we could afford to pay off all our car projects and take a vacation or two.... :twisted:

You MUST already be smoking meth to keep buying old Dodges like you do! :lol:

zing! haha *pokes fun*

[Ryan T]

Meth kits can be had for around $300-$400 and would allow me to run around 10psi.

[Ryan T]

Compression is changed via a headgasket. I'm keeping the stock headgasket for now though, that's why I'm limited to around 7psi. If you start pushing more than around 10psi you have to look into things like the turbo tranny's, injectors, fuel systems, pumps, $blah, $blah, $blah.

Lol, you pay for my fuel system and I'll 'deal with it', until then I'll be at 7psi. I'm well aware of the issues and concerns related to going turbo.

Dont mention meth/water. Run off the wastegate at 7 psi. My friend which I helped install (94 Toyota Supra NA) had tranny problems and has spent over 6grand WAAAYYYY more than he expected. He was the same guy like you thinking, oh well its cheaper to boost the NA, there are so many small issues you have no idea how much it is going to cost you.

Ryan you know im behind you being boosted, in fact I like the idea your doing 7 psi, but dont be stupid and dont be greedy.

Compression is changed via a headgasket, which is needed anyway on that vehicle to pretty much run any psi. Ryan, youll get away with 7 psi, and I know you know that, but you will be changing the headgasket down the road, keep it conservative and you may luck out and run 30-50k miles never needing a headgasket.


DO NOT, I REPEAT DO NOT RUN METH. Your vehicle has headgasket problems at 10 psi, do not think meth is your "fix" to allow you to run more. First is the problem of pump failure, yes fixed by a safety valve that pops down boost when line pressure falls below 150psi. However, this is like nitrous, done right, it can be a huge advantage, done carelessly and youll end up like every other dsmer on the side of the road with their overboosting and overeagerness.

A good kit with safety valves, large tanks, and activations systems, with (very important) a GOOD pump, good jets, can be had for around 400-500. However, controlling this system effectively (versus running just the boost pressure source), as he LITERALLY does not have engine management.

Make it simple, TRUST ME, I work on my vehicle myself, have done all the upgrades myself to my turbocharged vehicle. You will have enough on your hands with the turbo.

Use that turbo kit, get an intercooler, and most of all, get an S-AFC, wideband, boost, and a water temperature gauge. Dont worry about oil pressure, its one of those gauges, where its too little too late. The professionals mainly log those gauges as they no longer use the stock gauges and also to figure out what happened....after the fact.

[WRXtranceformed]

I thought it goes without saying that you'd need some kind of engine management to run meth. You do realize that he could run meth without running higher boost right? If done properly and monitored well, it will decrease the chance that problems could develop sooner as opposed to much later. It will give you a lot of leeway too during the winter months when the air gets colder and denser and the gas gets crappier.

I too have done all the upgrades to my (previous) vehicle, and I would strongly recommend against using just an S-AFC to tune your car. I know costs can rise quickly when you're undertaking something like this, but don't cut corners and use a second-rate EM like those DSM boys like to do =P

That Supra guy at the last car show was using an S-AFC to tune his car and I wanted to kick him in the teeth. I know, I know...the Supra engine is very stout, but in my opinion the only reason why his hasn't exploded yet is because he's running meth 24/7. That guy is probably leaving like 50-60whp and who knows how much safety margin on the table by not using a decent EM.

[D_Eclipse9916]

First of all, with no fuel mods, and no tuning, the s-afc is fine for logging what is going on with his injector duty cycles, thats the ONLY reason S-AFC should be used. I personally use DSMLINK.

Ryan is talking about a VERY simple setup. There is no need for engine management if he DOESNT run meth, doesnt run anything else.

[WRXtranceformed]

I might have missed it, but what is he doing about boost / timing control etc.? Did that kit come with a stock turbo Supra ECU w/ mapping? I just didn't see whether it did or not.

no, no, impossible. rob knows more than you about turbos... you listen to him! or else!

[D_Eclipse9916]

As was mentioned several times, he is running off the wastegate with no timing control.

[WRXtranceformed]

As was mentioned several times, he is running off the wastegate with no timing control.

And the car is going to run fine on stock fuel trims and timing? I find that hard to believe if he's running any boost at all....

[Ryan T]

There are more na-t's than I can even begin to count running on stock fuel and timing while tuning with nothing but an safc. They are everywhere and running just fine.

As for Wayne just using the safc and meth, he knows what he's doing. He ran on the single without the meth for monthes without any problems and then added the meth for a little more power and a little more boost. All the meth is doing for him is allowing him to run 21psi instead of 17psi. This is his 5th supra and he has never run a full EM system and has never had a problem with any of them.

A full EM system would be good if I was running higher boost or whatnot, but it's certaintly not necessary, just handy to have. I would love to have one, but over a grand for fuel management on a 300whp car is more than I'm willing or able to spend right now. I don't consider an safc to be 'cutting corners.' No tuning at all would be cutting corners (some guys have done that without good results), safc and a wideband is a way of tuning that doesn't cost more than the kit itself.

[Dave]

pistons and HG are the cause for the compression difference, IIRC. Eventually, he might need to switch over, but as long as his engine is healthy and he doesn't get stupid, that will be a long time down the road. That said, a decent turbo, even at low boost, makes an NA supra very formidable since it will have the better response of an NA car b/c of higher compression, plus all the benefits of a turbo. As Ryan said, these cars run just fine on stock fuel and ignition, as long as you don't get too greedy with the boost controller. There are tons of examples and they've pretty much perfected what is needed for it to be reliable. I know Thayer has done the research and I know he wouldn't skimp on it just to be boosted, so what he's saying here is definitely going to work. I'm just excited for it to be done, since now he might have a reason for me to trade with him for a couple days ;-).

I know the 2JZ is the Jap's answer to the Ellis Juan (God's motor), but if what you say is true that's pretty impressive. I mean, even the majority of the IS300 guys who are boosting their 2JZs are using Greddy E-manage or MOTEC or something similar. I'm sure the fuel systems between the Altezza and the Supra are pretty different though.

If you can get away with it and it's tried, tested and true that's fantastic, that will save you quite a bit of cash. If it was me personally? I'd look into SOME kind of EM or possibly even a TT Supra ECU swap if such a thing can be done. It would go a long way toward getting the most out of your investment... especially since this is your daily driver no? Hell, even my old WRX was only 285whp and it was running on a piggyback EM.

And I still think Wayne needs to get his head checked With that much power and that much modification to his power, I still can't believe he's fine with skimping on engine management. For someone who claims to run 10s and then tells me that "Oh I just add more fuel and turn up the boost when I want to go faster" at the car show, I'm definitely surprised that his car is still together. I still give that to the combination of a great motor and the safety margin that the meth is giving him :wink:

On the contrary....

[CaptainHenreh]

Lee, I imagine most guys running Turbos on the IS300's are using a full blown EMS cuz of OBDII.

Also, the turbo 2JZ and N/A 2JZ are very different. The cylinder heads are different, the ignition system is totally different, the only thing they really have in common are the block and (I'm pretty sure) the crank.

So you're saying the TT supra ECU wouldn't work then?

Yes, it won't work.
