Help me with my Supra Sequential Turbo'd Honda Project!

[thekyguy11]

Hello. I am new to this forum. I joined with the intentions of learning more about the Supra Sequential Turbo system, and to seek help with my project. I own a 2nd Gen Integra (I LOVE Supra's, but they are out of my league, price-wise) and I was just about to complete a turbo kit install on it. Then I recieved a phone call from a friend that was selling a pair of turbos off a twin turbo supra. Long story short, I bought them thinking, "im going to make my car a little different than every other turbo honda on the road." So I'm selling the single turbo and using the supra's.

What I have so far is the two turbos with the WG and EBV attached, and the top two pieces of the downpipe. My plan is to use the turbos the same way they worked on a stock supra. I've been studying how the SSTS system works, and I fully understand it now. But here is the problem, I don't know what year Supra they are from. I can tell you the turbine inlets each have 4 studs that hold them to the manifold, and the spacing is different for each if that helps. I also don't know where to get the EGCV, or IACV, Pressure tank, 4 VSV's, and a few little random parts to make the system work on my car. Obviously I need to build a custom manifold, which will basically be a modified log style.

So I turn to you, Supra owners, to aid in my project. I have a full understanding of how engines work (I've built a few), I do my own tuning, and I am quite familiar with forced induction. My goal is anywhere from 300-400hp and I want to prove that a twin turbo 1.8L doesn't have to have horrible turbo lag. I've got it all figured out how I will trigger each VSV and how I'm going to tune it, but I need the OEM Supra parts, and more details on the system to make it all work like it does on a stock supra.

I can only dream that one day I'll own a SICK ass Toyota Supra. For now, this will have to hold me over. Thank you VERY much in advance for your time and information.

search supraforums.com for sale section. Plenty of mkiv's available, as well as ebay.

I think your goals might be a little lofty on these, but best of luck. The low end of what you are looking for might be attainable, but the turbos aren't well known for longevity at elevated boost.

I would think that the smaller units on the 1JZ might be a better match.

I agree.

I know you can't really tell by looking, but these turbos are pretty tiny already. The 1j are even smaller, are they not? I'm thinking the ones I have may not be enough to reach my hp goals, but I wont know til I get it done and dyno'd.
