Some of the highlights include MPI converstion, E6k EMS, .020 over forged pistons, header by Chad, oversized sway-bar, knife edge crank, TD06H 20g, *DM 3" exhaust, SS valves, and cam (389 I think).

Well, the new turbo is a Tdo6h 25g syty 8cm2 from Turbolab 9blade turbine, 6+6 25g billet entended tip wheel.

Finally got it running again and its a bit rich ran it a short distance to make sure no funny noises or leaks. starts to spools 5psi by 3000rpm and hits 12-14psi around 4500rpm. which wasnt expecting and its pulling hard by that time.

Time to set Dyno time and tune, looking for 350hp and that in torque at least. lots to learn here. thanks again everyone.

With that small of a turbine you'll make way more torque than HP but 350 HP seems pretty realistic.

[SSG_CARTER]

6h considered small? Hoping to support400 or better

[SSG_CARTER]

Sy/ty 8cm2 housing is larger than the standard starquest 8cm2 housing. The 10cm2 would have quite a bit more lag the hit on this is impressive. At ~14psi

[Chad]

Stock manifold?  They support the stock TD05, TD05H, and TD06 turbines just fine, but if you are putting a TD06H or other non-stock larger housing on there, that may be limiting the potential of what you have.  You will still hit high torque numbers, but your HP won't reach potential.  At the very least, open up the collector to match the 10 CM housing.

[SSG_CARTER]

It’s one of your headers Chad and it should flow well. I will continue tuning. Pulls well though

[SSG_CARTER]

Comments flames critique. Any info before the dyno? It is a 6h turbine wheel in a syty 8cm housing. Mismatch what?

[scott87star]

You don't have to reinvent the wheel, here's an example with power greater than torque.  There are more.

Very much appreciated. Time to read .

[jinx]

i wouldn't get hung up on that "hp greater than tq" peak business.... especially on these motors
All u need is a lazier spoolin turbo to achieve that
then u lessen & miss out on the natural midrange tq swell these cars r known to have. A deception imo

for instance, in that G54 hx35 example posted.... on a divided header, you'd be knockin 400+ ft lbs @ 4000 rpm
heck, stock 2L DSMs do that on their 7.8:1

06h in 8cm is a decent size. Forced performance DSM hybrid turbos shows u what that turbine combo is good for
turbolab video say that combo is a popular starion request iirc

[SSG_CARTER]

So you're saying is the torque is going to be there with the turbine and housing.
So get the fuel right get it to a dyno. setup the dual stage and enjoy.

The turbo is a turbolabs of america  product. Those guys are great.
9blade O6h. stated earlier the 12-14psi small pull felt good boost came on linear in 2nd.

Thanks and keep the info coming.

[SSG_CARTER]

OMG! this thing is a Monster at 15psi wt.... happened! the 20g had nothing on this, Even at 20psi it wasn't this strong.
The smooth torque is addicting. dyno time next week. She is rich now for safety 11 AFR,  O2 sensor needs replacing ran some 112 and 93 octane.
Pretty happy though tranny is not gonna like the torque

[Ptracy262]

interesting read,  I'm right behind you and I'll know in a couple of months what it feels like.  But I'm staying with my setup 20gTD06H 8cm2 on a T3 tubular chad header.  MPI etc...

builder wants me to dump that setup for a ball bearing type scroll setup,  but I only have 300 miles on mine before the balance shaft went on a cheese rebuild,  now I'm going fulling forged (already have L19 Head studs 120ftlbs of torque to keep the head down)  20 g will be easily in the 20 + range of boost,  maybe can keep up with the 25.

in the end for me,  if the bolt on stuff is outdated  then yes I'll upgrade,  but 5k into this next project and have 2k on 300 miles of use of a 20g FP / T3 sy/ty turbe header setup,  that felt awesome until the balance shaft went,  let see.

[SSG_CARTER]

I didn’t know it would spool as fast as it has. Scares me ! Either I did something very right or horribly wrong. Timing is dead on 10 degrees fires up no problem. It is pig rich though, I’ve changed the oil And filter a few times. No leaking injectors vac lines are good.
Crazy part is it’ll hit 20psi in 2nd gear if I let it eat. That’s the scary part. I have it set at 20 and it pulls like a beast. Not the massive hit of a smaller turbo just nasty torque. Which I happen to Love.
I will keep all posted wanting to hit the dyno this week if possible.

[Funky Phil]

The different variation of td06 wheels fit well with 2.6’s. 25g’s are 67mm wheels correct?

What timing and fuel are you running? Dont crack it.

[SSG_CARTER]

Thanks Phil . Base timing 10btdc I will get timing map and data log and try and post up here. I don’t want to crack it. Fuel is race mix 116 and 93 . Planning on taking it to tuner next few days. Finally found a 25g compressor map happens to look like a 60-1. Max boost for me going to Be around 25 if it looks safe at the dyno. She is strong. Following Killaphil is do a base, 15 and 25psi pull.
We’ll see how it goes if I have the safety margin.

[SSG_CARTER]

It’s a 60.5 x 78 x83 mm compressors 6blade.

[jinx]

luv when a boosted motor feels like it grows into huge displacement, rather than the normal smaller turbo 'hit'.
sounds like a good combo, that should rip once dialed in
turbolab also sometimes use billet kinaguwa? compressor wheels.... gtx30, gtx35, etc., designed for mitsu applications

[SSG_CARTER]

I agree. it really made me appreciate the MPI move. Tuning on my own till dyno time. 1 and 2 are quickly dispatched 3rd a bit slower but while it's hitting target boost you realize, "This is going to be a Big Ticket" then you slow down. Never been to a dyno so ths should be an experience. Thanks for all you guys input. I am going over my notes and reading the manuals to make sure i have my bases covered. i will video and try and post it.

[Bradrock]

What intake manifold are you using?
