So its remapped, so is mine, for uk fuel which is running around 310bhp, his may be running 320, no real comparison unless you write his entire spec down is there?

Tony

 

Have you ever competed in a sprint? A quick spooling 360bhp Spec C should be able to easily fend off or be close to the times of a strokered 500bhp car, a gt30 is way more laggier, meaning 1st gear corners whilst the twinscroll will go round and spool up with ease.

Trackday would be a different matter with equally capable drivers.

 

lol, I've been watching this thread for the last couple of days waiting for it to turn into a ***** waving competition

 

The twin scroll does have its benefits, early ones like mine can suffer at the top end, but your changing at 7k anyway so it wont really be a problem, best for twisty roads where you would normally be caught out of gear but you dont quite anymore .
Newer and better twin scroll turbo's are the way forward if they can give you the low down grunt (with the aid of vvt/avcs) and top end power.

Now, have you done much with the gearbox/clutch on yours and did you get around the issue of over heating brakes? (didnt someone do a mod for that with air cooling from the front bumper?)

Tony

PS, Extreme did mention that the RS's were the ones to buy if you wanted a fast/better handing evo

 

TOTB should be interesting this year.

Hang on in there Tony,your doing fine.

 

Tone, I have the short rs box, it basically tops out at 140mph at 7k rpm, its a decent box, although I can attest to the prob you mentioned earlier in the thread, with regards to changing up or down dilemma, sometimes a bit longer gearing would be ideal, and then sometimes its ok.

Clutch is a twin plate but might have to move onto a triple plate as just had a gt35r fitted, we'll see once mapped.

Brakes have always been ok for what I use it for, uprated discs, with carbo's xp10's all around, uprated fluid, tendency to lock up under extrem braking as no abs as standard on these.

Brakes, AP's pref (had them on my 8) are the next choice mods.

 

The exhaust ports are better on evos, hence why the make more power on the same turbo compared to a Subaru.

Banny

 

Not to mention the shorter pipework!!

 

To be honest, there is nothing of my motorsport knowledge in my JDM STi, all i've done is set the camber and toe for a fast road car that is used daily, plus had a remap for UK fuel with a milltek exhaust and a change of brake pad material for fast road which is probably a bit hard for a sprint.

Had i wanted to set it up for the scoobysprint series i could easily have knocked time off by going more radical on the cambers, fitted some decent grippy tyres (it's on the stock tyres which are a bit hard for a sprint) and softer brake pads. It's got the same suspension and brakes it left the factory on 4.5 years ago, not even a change to ARB has been done, it all had about 35K miles on it at that time, so no new stuff to help either. I just did the two events for a bit of fun.

Bang for buck they make a lot more sense than modifying a classic these days, of course for something like TA to be competitive you have to modify the cars a lot more, but i'd wager a similar spec Classic and New Age would be very close on pace, it's just no one has done a New Age car to the same high spec yet in the UK, the USA they are more into using the New Age cars in TA.

I was due to drive an EVO9 GT lightweight in TA last year, but it never happened sadly, no doubt they are damn good cars too.

 

Thread revival... Decent read this!!!

 

I don't believe the hyper cast pistons to be stronger than a uk spec newage piston tho?

 

+1 subscribed

did John have his car set up at Chevron?

 

eee by gum.

I have a bit more torque now

Simon at Chevron and I work together on quite a few aspects of the car.

 

i live a few miles from stafford, ill have to pop down in the jdm see whats what

 

Jeez didn't realise lol

 

Out if curiosity, what cams do the jdm's use? As from reading on here the uk and jdm newage heads are the same but the cams are different which aid spool and possibly torque on the twinscroll setup

 

This past week or two all I've had running in my head is should I have bought an Evo over my Type R?
Yes I've gathered that the Type R is a lot more raw. But when it comes to wanting to poke a bit more power out of it, it always ends up more costly on the Subaru's part and its not just by a little bit. My Turbo pretty much stops me @ around 330bhp (VF24) The gearbox has already looking like its wet the bed and is currently waiting replacement. Even then, once its replaced they aren't the greatest over 350bhp I've gathered. Then the FMIC will need put on again something which the Evo has standard. Once all this has been done coupled with a remap don't even get me started on the brakes and then you'll always have in the back of your mind when is this thing going to spin a bearing no matter how often you change the oil/look after it.

Yes you'll all say you should have realised this before hand, but I wasnt expecting it to be as bad as this - thus I will also say. 9 times out of 10 the Evo is a better car standard and is also more capable of accepting power more cost effectively.

 

Buy a Newage STi if you want cheap tuning.

 

Possibly. However, most Evo 5/6's have rust issues (my friend is having a nightmare finding a clean one), some don't like the AYC.... which often goes wrong and costs £££ to fix, and some find them too clinical.

I still quite fancy a VI, an Extreme especially, but for some reason I've never jumped ship.

 

Hi Gary mate
Have you still got that blue type R?
Hope you are well

 

Hi Steve. No, sold it earlier this year, still got the Newage though. Hope you're well.

 

I'm loving my Evo VI Tommi Mak, spool up is crazy and it has vitually no lag...354bhp and 378lb ft of torque keeps me smiling

Is a JDM so it's nice and clean too

 

Is it twinscroll? And what cams does it use? Always loved the Tommi mak

 

It is twinscroll... it has a standard 7 engine as the original engine was tuned to 500bhp and he swappedthe engines over when he bought a 7... the turbo is standard Mak item rebuilt about 8k miles ago and is running 1.5bar

The TME is the only Evo I wanted really and its awesome... pics in Members gallery

 

Seen it and love it mate. Even the black roof Ian ott. Just the right amount of power for the road also

 

Mervil - How does it compare in terms of driving characteristics with your Type R you had? Ideally when I look at Evo's I do like the old shape sometimes but as said the rust would probably be my main concern.

If im honest im actually a sucker for the Evo 7, I like the front end but im assuming these will drive differently as compared to the Type R. As just now Im seriously thinking about selling up to fund and Evo now.

 

I was going to look at a 7 until my 6 came up for sale local to me, apparently the 7s are prone to rust more than the 6s...

Driveability wise, the Evo is a lot smoother, sharper steering and I feel myself being able to carry more speed into the bends! I do miss the sound and being able to kick the **** end out with the DCCD !

 

Yeah, I think deep down If I do sell the Type R ill miss it to a certain extent.
So would you say given the choice of a B road blast you'd pick the Evo instead?

 

Only a little bit more eh John

 

Is not just the pistons, they are very strong but more suseptible to det (more brittle due to the silicon), the rest of the engine is improved over a uk car, the likes of the crank that supplies better oil feed (considering the bearings are an issue and you see more failures on the UK sti engines because of this), it sort of speaks for itself

The latest JDM cars have a different engine now (2ltr) which is an improvement over the first gen twin scroll units.

John, what power are you pushing now??
