are you sure that it's correct to connect the catch can to the throttle body? On a natural aspirated engine I would do like that but I don't know if or how it will works on a turbocharged car!
Most says to connect it in front of the turbo compressor because there is a little vacuum made from the turbo wheel sucking air from filter...
I would suppose that to connect the catch can to TB in a turbo engine you would need a one way (check) valve...

In the normally aspirated Supra, as with any normally aspirated car, these vented are plumbed into the intake near the throttle body. This effectively burns any excess gases which escape in the combustion process. However, in the turbo Supra, and again as with any turbocharged car, you have an additional problem to worry about -- intake plenum pressurization. If a turbocharged car was only connected to the throttle body, every time the car hit positive boost pressure, the pressure would effectively pressurize the PCV system and force additional air into the motor -- and I don't mean where it should be going :-). That's why the turbo Supra PCV pipe is connected to both the throttle body and the intake pipe (before the turbo). That way, under boost pressure, the pressurized air coming out of the throttle body now will take the path of least resistance and skip past the valve covers and instead vent to the intake (accordian) pipe. This will also create a low pressure area over the hose barbs and generate a slight suction to pull out any excess pressure in the head.

Catch can in.

From valve cover breather:

To catch can, other hose goes to throttle body.

Defently do not boost with the way you have this connected or atleast the way I understand it

after catchcan you can connect hose close to the to turbo inlet or leave karter gases to go free at the athmosfere that is not ecologic but it works on my turbo cars (I use very long hose going down to the gearbox monts )

if you return karter gases to the thorottle on boosted engine than you will pump your carter with boost and you will have a massive oil leak ,if you use a vacuum valve it will not work good again because in boost karter gas pressure rize and again you will have oil leak

sorry my bad einglish hope you undarstand

Yeah I fixed it already, I put a breather filter on the one side.

plug and play mS? more details on this please. I have a haltech E8 that i wired in last summer but due to time problems trying to work out some glitches I had to swap all the stock stuff back in. I really dont want to go through the trouble to wire it all in again, so if i can get a pnp settup that would be sweet.

plus, ms seems to be getting better by the day...

PM tglazier.

He built mine and did a good job.

I'm very impressed with him.

I'm having problems with the lc-1 though and therefore my car is sitting in the driveway.

tglaze · « **Reply #216 on:** March 09, 2009, 10:43:39 AM »

nah, just that there are more people using it so there are more success stories.

its just like you with your haltech experience. had that been MS the user would have blamed it on ms for being inferior and thus it didnt work out..or something along those lines.

fair enough, but with more people using MS there is more help to be found with MS. I only know of 3 or 4 people running a haltech on an e30, I'd still like to do it if possible cause its a great system, but if I can get an MS system that will plug straight in that would be very convenient.

I'd like an order of epic win pl0z.

MegaSquirt is done and semi-tuned.

Need to call Todd tomorrow, I have a few questions for you buddy.

I'm slowly gathering parts for this build. White325is is preparing a mani for me from a M50 mani. I'll be running a TD04-11B from a 524td, it is a Garrett turbo and fairly small but should be enough to boost something like 6-7psi on a stock engine.

Danny, do you have any info on the mods to the Mani, especially at the flange, did you make a spacer to raise the turbo a bit? pics and measurements would be awesome.

How much did the MS set up cost? I have a chip right now in the car and was thinking of going with a custom chip but if MS is working well and maps can be found fairly easily then I think I'll go that route.

deekay · « **Reply #220 on:** March 21, 2009, 04:44:23 PM »

naika: everything i've read said the 524td used a small-t3 garrett (TB0324, which should still be good for an M42).

td04 = mitsubishi turbo.

unless the diesels in europe got different turbos, in which case you should ignore me entirely.

what a kick ass build man. props!

great job Danny, you're a great guy! maybe i should do the same to one of my M42! however i would ask you few questions... have you ever thought of modifying the timing by moving sprockets on tapped holes? by retarding valve opening the engine can help the turbo filling better the combustion chamber.
then, do you really need an RRFPR pressure regulator or you can do the same with a normal pressure regulator attached to the aspiration of the turbo?
last question is about the brake booster, running in turbo configuration you remove it or it works fine anyway?
hope you can understand, i'm italian and my english is not so good, expecially when talking about such techinical things!

I did think about it, but because of my stand-alone megasquirt, I no longer have to.

That's basically what an RRFPR does. If I understand the question right that is.

Booster works fine. No worries about your english, I'm happy to help.

Post up the part number, should say TD04 or TD05 and then a dash and a number and a letter.

Never did this... sorry. Got around to looking at it and here's a few pics. Turbo is a TDO4HL-15G. Came off of some sort of Volvo. Was told it was small enough for 7-8lbs and very early spool, ~2500rpm. You think this is accurate?
