This engine is still being tune as we speak. I am getting a 3 Bar Map sensor tonight. I already have a RPM signal unit already. The Wide Band Innovative Unit will give me all the info such as PSI, RPM and AFR. From there i can slowly alter the fuel map.

Thanks to Eric from B & E Customs for helping me.

FYI: You will hear Tial 50 mm BOV and it work and sounds like sequential BOV. This is great because this will prevent engine from dying. Sequentially release the air will prevent engine from dying. I had Greddy Type S and my engine dies all the time due to air being release all at once.

With that .68 a/r housing, does power drop off up top? I am looking at the GT40R or GT42R for the 1uz. I have a GT30R .63a/r on my 2L 3s-gte and LOVE IT. I see why the GT series is the best and worth every cent.

David--any updates on latest state of tune and of course, the requisite dyno numbers?

 

[RUN011]

just a quick question, are those master power t70 turbos any good? im looking at using one of those as they are cheap.
its a .7 front housing with a .85 rear is that big enough?

thanx for the insparation lextreme, you make things so easy for us
got any more vids of that beast of yours????

 

[Lextreme II]

I think the Master Power T70 is well worth the money. It has compact turbine housing and it worked great. Get it......

Hi Lex, is it all working ok with that manifold setup like that, i ask as you know im about to make my manifold for my turbo setup and as i dont have much room in the IS bay, this could be a good way of doing my setup! what size is the Turbo A/R cold & Hot side??

all so what power is this setup puting out? have you had it on the dyno yet?

Thanks

I have seen a IS300 with a VVTi swap and turbo with T67. He mounted the turbo in the passager side (LHD) under the car. Works great. My set up work fine for the purpose. I got 397 RWHP with 18 psi with bad tune. I would believe with better tune and without electrical bug in my car I would get alot more.

Well done.. Any upgrades or have you fitted a blower...???
