Tottaly agree about the turbo comment,but I can imagine it been a bit of a handfull down a back lane?then there's the worry of the diff exploding
Sometimes I wish I had gone turbo,but then that thought disappears when I go out in mine :-p
boost and vtec come in at the same time, your above 4500 when your driving hard there is no difference to stock apart from twice the power without vtec catching you out.All non belevers that have driving the car agree its how the car should have been ,as for the diff ,ive got friends in the states pushing 650whp with no problems.
I'm not a non believer,all my cars from the age of 18 have been turbocharged and I know that's the way forward for big power,all I'm saying is the power delivery is different(sudden surge of tourqe unless your running a vnt) which can cause traction issues,my dads old rx7 470bhp was a handfull down a back road and you find that it's wasted power.
Apparently a s/c vx220 is a lot quicker than a vx220 turbo around the same track.But probably isn't a quick in a straight line
It's good to hear that the diff is stronger than what most people say,as I was expecting mine to pop at the dragway the other day.

Well a little late from me but I have a 2007 DBW with TTS kit and Hondata and it has been faultless since the latest remap. There was a CEL when first setup due to the air pump but that was removed when Hondate released an upgrade. The car even passed the MOT this morning (it has 1,000cc injectors but the emissions were close enough even with the decat pipe )

Clearly there will always be a TC/SC debate usually driven by fanboys as everyone thinks their system is best. I have had both twin turbos, supercharged and large volume NA and they are all different.

What I would say is that no end of hardware upgrades will compensate for a bad map. It is the mapping that makes all the hardware work together and it takes time and money to get it even close to OEM but it would be unrealistic to expect an OEM product unless you have some serious time and money to invest.

I had a turbocharged MX-5 several years since and was really disappointed with the package (especially after the £ spent) but some further £ and a remap by a specialist (MoTeC) and the car was transformed.

If you can work out what parts you are missing , regarding the pipe work let me know, my car will never go back to standard so the parts you require will be hanging up on the floor somewhere. When I get home at the weekend I will have a rummage for them, they will be free to a good home, so don't worry about cost.

NO FLASH PRO its was a AEM v2 for DBW only , to me it wasn t what i wanted all the booost was way up 7k above and it was very flat below that even with 2 different mapps .It would nearly stall when comming to junctions ,idle wasn t smooth could go up then down .I going NA all the way now as to be fair the suspension setup is exellent . I Felt i was allways on edge with the car after hearing so many horror stories on this forum.Running it on VPOWER only around west wales was a problem as the closest one to me as 40 miles away meaning filling up 5 25lt jerry cans as storing it at home .Anyway it off now and all i want to do is get it back on the road asap with some help form you guys .So if you could direct me to some pictures of the engine bay so i can find out where all these vaccume pipes go and see if there are any more parts i need to order to finish getting it back to standard.
Although the car produced power once it was revving it was as flat as a pancake off boost, which would suit some people but it wasn't what I was after, hence the reason I've gone turbo.i got caught out by a Golf diesel, untill it was revving.

Dixon tells me the Cel is on all the time with the Aem because there is no provision fot the wheel speed sensor..... I have to agree that the Cel on all the time will get on my nerves.
The map is important, I'm literally wringing every last drop of power out of my car with the ECU I have, its not suitable for a track due to the timing i run and AFR. And the amount of times I seen vtec left at the stock point on an SC amazes me, there lots of mid range your missing out, unless its dropped to around 3500-4000RPM depending on car. Also its goes for not dispatching you into the nearest hedge .

Haha yup I've been caught out before like that, with an SC you have to pre-empt things and need to chose the correct gear and be at the vtec engagement point.

The other day i knew someone in a gold edition 30 was going to try it on, so i had my car in 2nd gear sitting at around 6k rpm going round into and around the roundabout onto a straight, as soon as the road straightened out i let rip, and i really destroyed it no contest whatsoever, he was definitely trying too as i had the window down and could tell. You can see where having a bit of skill comes into play, with a turbo you could doddel about and put your foot down (in the wrong gear/zone) and you wouldn't be out of 'the zone' and pull away easily.

If i could put up with heat issues and spending even more money then I'd have a turbo, it has crossed my mind but tinkering/tuning again from scratch for me...no.

And the diff issues, MB got my Diff i was hoping the 4.56R ring and pinion would be okay but alas the pinion was missing a tooth and there was excessive crown wear, however it had been on my car for 6 years and the extra power probably sent it on its way, so more power does destroy them. I'd like to add i was mechanically sympathetic on the clutch like i am with all of the car.

You still need to be in the right gear with a turbo car,as I have been caught out a few times in the past,the only turbo car I have driven where this doesn't apply is my dads noble 3r,but that has twin vnt turbos and has the same characteristics as a v8,I'm sure the new 911 turbos are the same aswell
Anyway your sticking up for the wrong team haha

I partially disagree, look at the torque and boost curve of a well setup turbo S, full boost by 4500RPM (depending on turbo) and it holds power/torque unlike a linear SC setup.

haha wrong team, yeah Turbos are for gays

OK thank you all for your help again Found the MISSING Air Temp Sensor which was cable tied to the bottom of the car and i didn t spot it , So i think all Vac lines are sorted and the woodfuff keys are out so its just a waiting game now till the missing Map sensor arrives in the post from Dixon .Still a few bolts and bits missing but they are nt that important .So once this car is out the way and on the road the next mission is a BUILT totally NA Tuned engine AND a lighter body instead of having a heavy s/c ./

Good bolt on's, crower stage 2 cams, and itbs. Recipe for a wonderful quick and nice sounding na s2000 beast.

I can see it being slightly cheaper than what you paid for the sc setup.
