Quick dyno session today. Poor bottom end because I think it's blowing the wastegate open, but this chart is still worth showing.

Run 1 is with the stock 2.25" NB exhaust (peak boost 5psi)
Run 9 is with an Enthuza 3" stainless catted catback (peak boost 7psi)

This looks like a really nice setup love the cast stainless manifold. What is the baseline on this car before turbo conversion? What is the intercooler setup?

Would really love to buy one of these kits when they come out and would like to shoot for 200hp 200ft/lb to the wheels which I know is really conservative. What psi do you think would take to get there on a stock 1996 1.8?

Thanks for taking the time to answer my questions.

The intercooler setup is a Precision 350hp with 2" coldside and 2.5" hotside pipes. The production intercooler will be a little smaller.

200whp on a BP05 longblock should take 10-11psi.

I don't have a baseline from my NB2, but Emilio was kind enough to shoot me a DRF file for a stock NB2 to compare.

There, now you see, the stock engine walks all over your tirbo at less than 2,000 rpm.

116 is pretty healthy for a stock NB2!

Hey Sav-

I just pre-ordered a manifold and turbo for my 94.

You're seeing the limits of the vtcs manifold in both the stock dyno and your turbo setup. What are your plans? Also this was 3" exhaust? I'll be throwing one of these setups on a vvt motor with a square top. Should be good.

Plans: Moar boost, bigger turbo.

CNC head too right? Can't wait for that to go down.

This car won't get a CNC head. It will get a built shortblock and valve springs but nothing else. No point in showing what the turbo kit can do if all the results are skewed by a $3500 cylinder head.

I was referring to the car curly was talking about. Oops. Moar boost was about you overcoming the vtcs. CNC was about mobius' car.

Yes, richard's build, sorry for the confusion.

In my experience, no amount of boost will over come vtcs fail.

EFR7163 and 30psi might make a den't in it

Could very well be the manifold, it did cross my mind. I'll have to live with it, since I want to change as little as possible with the stock motor so the results are as relevant as possible. The exhaust is a full 3" Enthuza with a metal cat and two mufflers.

I may throw a squaretop on it later on, once all the "stock bottom end" data is collected and published, just to see the spool difference. The built motor will definitely breathe through a squaretop, so it will be interesting to see how close the 6758+8.6:1+squaretop combo can come to the 6258+10:1+VCTS combo. I've also got a VICS manifold here so that's another option.

Oops, did not read up. Yes, I have a couple of people throwing these setups on CNC heads. One 6258, one 6758. I am eager to see what they do

I'm glad you're sticking to basics first, yes we all know the better mani and baller head will produce stellar results, BTDT, but you want the kit to be the hero of this party.

I got a ride in Savington's car the other day. It blew my mind. The boost is instant, it doesn't feel like any turbo I've ever driven. The power is also totally linear. It basically just feels like a much bigger engine, save for the wooshes and pshhts'es. Super impressive.

It will be interesting to see the results on my car. My engine has Manley rods, stock 10-1 pistons, cnc vvt head and a squaretop matched to a skunk2 TB. A very mild built engine. With a c30-74 it made 217/166 at about 7psi. With a 6258 and 3" exhaust, I am excite.

Edit: +1 valves and stock cams in the head.

Sorry, cnc head disqualifies you from saying "mild built"

Ah lol yes I thought that after I wrote it

Initial plan is to create a 230 tq plateau. 300 whp should be an easy consequence.

How much more HP / TQ are you expecting from the square top?

Powerband looks great. Interested in some 10ish psi runs, especially to see low end torque. Some of the tighter autocross courses put me at about 3000rpm in 2nd gear
