Ok everyone, I hope that it isn't to late for something like this. I've spent a few hours compiling all this info from about EVERYONE's swap threads. If I happen to just receive bad criticism, well then I spent all this time compiling this for the sake of making my swap easier when I get back stateside. The file is about 26mb or so, and contains a lot of pictures. The hosted links are below for download in Microsoft Word and PDF.

sweet upload but it still doesnt answer the question im having on what regulates boost. if the front wastegate is operating for both turbos and its just free flowing whats stopping it from over boosting? why cant you just toss a boost control on it and call it a day?

That would be a good question to ask the guys who went sequential doing the TTC mod on their swaps. I put the manual together just to show what to be done for the swap, plus Im going single so I didn't really dive into it too much.

However, from what I would say- you'd be right in your logic of it possibly over boosting. I haven't ever dealt with a stock Supra setup. All of them I've messed with have already been converted to singles. I know that on the ol DSM's there was a boost regulating solenoid that was controlled by the ECU to allow vaccum to pull open the waste gate at a certain time.

I happen to find that searching for stuff in Google gives me better results than the My.is search function. Try looking up 2jz-gte TTC mod there. If you weren't aware, there is also an Electric TTC mod. I haven't looked into this at all, but you may want to dive in there.

I had the same question as I was doing my swap and I've just come to notice that since I finished the car and have been driving it in all sorts of situations and conditions, boost never seems to go past 11lbs. I have however had one day of boost spikes up to 15lbs, but to my knowledge, that is still a safe number. I did come to realize that when I hit that spike, at the time my car was running super super rich, so I don't know if that had a lot to do with it or if I was just pushing the car too hard. Ever since I have fixed most of my mechanical issues, boost never peaks pass 11lbs which I read is stock levels for factory twins.

I remember reading in someones threads about them hitting boost spikes with stock twins, as well as installing boost controllers and running them at 15 psi or so. I've also seen that some peoples just run between 11-13psi naturally and that is how they have left it. They've seemed to be reliable at those levels and make the power and performance that those doing the swap were looking for.

Well lets look at it this way. Suppose I wanted to run 15 lbs. Obviously I would need a controller to make that happen. Ive been wondering if people are still routing it through all the vsv solenoids or like what picture i saw where they just ran the 2nd line from the solenoid directly to the manifold for vac.

i feel like im overlooking something big time. i cant seem to comprehend how the wastegate on the first turbo controls spool for both turbos. everything ive read says it basically allows exhaust to reach the 2nd turbo to spool. BUT you can plainly look at the manifolds and see the 4,5, and 6th exhaust power flow directly into the 2nd turbo...

On the vsv's etc, I am not completely sure of. I put in the manual directly out of peoples builds what they posted and did when then kept their twins. Yes obviously you would need a controller of some sort to increase the boost pressure..

Glad to be of help! I am waiting for a member to get done with a manual pedal install into an auto car and i will possibly add that to the manual as well..
