Is the Saab engine so much better? Can you not pull the same power out of the existing 2.2 plants??

 

The jury verdict is not fully out yet.

Some will up the internals, because some graph says so, and some will push it to 350 on standards.

 

Time will tell.

Goodness, I can't believe how many NA owners are building/refurbing new engines. I thought the Z22 engines were good for loads of miles (ie 150,000+) so long as the oil is changed?

 

Good luck all

Which means we could still sell our z22se for good money

They're a solid engine but trouble is when pushed to near 260 it's on the limit. All these guys (including myself) want to skip stage2 and go for stage 3/4 as its cheaper. The amount of parts you need to buy for a rebuild costs near £1000 more than buyiing a brand new engine with 90% of the parts fitted.

Ah I see now, almost as cheap to start from a brand new engine and with the added benefit of brand new parts. 

 

Getting a 300 to 370 BHP engine into a VX is a laudable goal (IMHO) and highly exploitable, particularly if it is smooth supercharged power. It makes me smile to see so many people pushing the power envelope these days

 

Hopefully someone (or a whole group of you) will invest some money in R&D to develop an inlet manifold and CC that will allow you to utilise higher levels of boost.

it's actually much cheaper to use the £714 saab engine than to rebuild a ten year old z22se engine

1. Chill. 2.2 crank, forged pistons and rods stage 2 LSJ cams,lightened flywheel and balancer delete, home build with vocky input on Dutch ECU software M62 charger ported head. Hoping for 300+ 2. Graeme. 2.0 Saab B207 with standard pistons and crank, Comp cams, chenge of flywheel (Vectra V6?) which may as well be lightened and balancer delete, plus whatever else Vock recommends (within reason) using M62 and dutch software (or standalone) and I'll be happy with 280-300bhp 3. Westkenbrit. Vocky fettled B207 (ported etc..), 2.2 crank, forged internals, siemens injectors, stage 2 cams (unless advised otherwise by Vocky) uprated clutch, dutch software, harrop, Pro alloy chargecooler, and baffled fuel tank, uprated fuel pump. 350+ But Neil and Joe would know better as they are doing it all 4. Chris. Leave it sat in my back garden until i can be bothered to pull it to bits. 5. Tony. Ornament. Going to collect all the adaptations and that while I decide what to do. 6. Smiley. 2.0 with head exhaust part ported, zzp or comps cams, lightened flywheel, external crank, water injection, harrop and obdtuner. 7. ufods B207r with standard internals,lightened flywheel and balancer delete, extrrnal trigger, Sachs clutch, 3" full Tullet, Siemens 630 injektors, Dutch ECU software Harrop charger Reaching 330 PS without water injektion Still searching for cams

Stig is there a reason why you are using the turbo cams over the supercharged, or is there no difference??

[vocky]

Stig is there a reason why you are using the turbo cams over the supercharged, or is there no difference??

He is running the dbilas z22se turbo kit

Because hes going for a turbo maybe?

Lol

We had a dyno run yesterday with some speedsters, and one was with the 2.0 Z20NET (=B207)

He was running very hot in intake temps earlier this summer (up to 90), before fitting water injection.

He's the first going on the dyno with a large pully though i believe.

 

So he did 306hp with an 80mm / 3.15" pully (1.38bar/20.0psi) (2.0 with harrop)

Ultimate did 330hp with a 75mm / 2.95" pully (1.55bar/22.4psi) He is now on a 70mm but no dyno yet. (2.0 with harrop)

 

What were the numbers again the Uk smaller pully dyno sessions did? (include 2.2 or 2.0 and M62 or harrop)

 

 

 

Also makes you think larger pully does not help that much with intake temps when on track.

I had hoped he will revcieved some more power with 1,38bar? What about the torque?

[Exmantaa]

From memory around 320Nm. (nice flat torque spread...)

But the measured revs (from the roller speed) were a bit off and when you recalculate the measured torque for the higher revs the Harrop comes around 325HP@7600rpm.

He will for sure scan the plot a.s.a.p.and post some comments on the HPTuner logs with water injection.

[CHILL Gone DUTCH]

Has anyone tried bio fuel mixture , to see if there is any significant gains in power

[Exmantaa]

Your blower set-up will love E85 fuel! (The US guys call it "liquid intercooling"..) Shame it's not easily available here in NL.

Need to tune for it though; BIG injectors and a capable ecu mapping like HPT or OBD Tuner.

[Arno]

Also really want to use a fuel composition sensor in that case so the ECU (if it supports this) can determine the % ethanol in the mix and apply compensation values so it can run on 'plain' petrol up to E85.

I'd be up for trying this.  I've done some casting before if you want to try to get something workable.
