We all know that cars all not all about power in straight lines, but something Spec C's and STi owners maybe interested in.....

For the first time last night I was able to compare my Spec C (which has only been modified with a sports cat exhaust and conservatively remapped basically for UK fuel - the downsides of owning one of the first imported Spec C's using first generation sports cat twin scroll exhaust system and 1st generation fuel re-maps) with a Tek 3, full decat and induction changed STi.

I have to say I was quite impressed how the STi went.... in fact I was very impressed!

While the Spec C was undoutedly quicker from 0 revs (spool up on these things is unreal), aspects of mid range were quite similar and I am not sure what effect the different gearing (in 5th & 6th) on the Spec C box has over a UK box - anyone know?

Obviously the main advantage the Spec C has is that in this form it is quite standard (as regards to engine and outright power). So the advice that I was given as regards to the JDM models being a better platform to start off with (as regards to tuning potential) has been sound advice.

It will certainly be interesting to see what differences the planned modifications make to the Spec C over the coming months (using the latest evolution of exhaust system and mapping technics, together with a brand new design of induction kit (for scoobys at least)..... and a few other bit's and bob's ).

Are you launching 'project scoobysport' again? Is this going to showcase scoobysport products? Will there be a new project in projects again?

PS I'd like to know when the A8 system is being marketed too; will you be fitting this to the Spec C?

whats a a8?

if running standard internals , will the difference really be that large if your comparing MY05 cars , I though both cars shared the same bottom end?

I have seen posts that the new JDM's have large port heads but do not know how large they are compared to the UK STI.

what is the rev limits on a STI UK v JDM/spec-c? if the rev limits are 1000rpm higher like on the classics , I can see the attraction with using a larger turbo.

I actually think the UK MY05 STI is a good buy , given that you can buy a brand new one for around 24k. it might be a bit heavier and miss a few nice upgrades like oil cooler and surge free pump but if your modifying , they could be added.

I would have thought the main advantage with a spec-c was how good it was "out the box" with just a remap for the UK. if planning lots of changes I would not think the UK was a bad starting point.I do not know how far your planning on going but if a built engine is used with a rotated turbo for example the difference is probably closer still. same with any planned suspension changes if they are on the cards. I think all the dccd cars share the same hubs now? , the JDM's do have proper spaced gears though IMO.

how much is a brand new spec-c with electric windows and central locking?

Who wants induction kits when you can have one of these

rizzy

what does that do?

T-uk, agree on the 'spec-c was how good it was "out the box" with just a remap for the UK'. Why mod a Spec C, when its supposed to be v.good to start with?

Daz34, nice air box but unless there is another box within it, then surely it'll get warm like the std air box - no heat shielding?

It's the new ITG one. Good for 450bhp they reckon.

spec-cie

8250 rev limit with only a small drop-off in torque 7k+ revs.

Main reason I bought my Spec C is how good it is out of the box, mainly due to better internals and lower weight. May upgrade it later but safe in the knowledge that ~350bhp/350lb ft can be had from it without any reliability worries (probably just with a remap).

shaun .glad you liked the way my car went .but your soec c is the b*locks and i would love one

Monkeh

carbon fibre is supposed to be a very good heat insulator, so if that air box is made from it, i doubt it will too many problems with heat soak

Your car must be very conservatively mapped Shaun. In my experience there is a considerable difference between a Tek3 JDM twin scoll -v- Tek3 Sti UK. In addition to the obvious twin scroll and increased rpm limits, the different heads and cams allow a very wide power band, the ignition timing characteristics suggest the JDM TS/SpecC share a similar camshaft spec to the older Sti5/6 whilst the Sti-UK is more in line with the 99/00 UK car.
Ultimately however, as we have found with the Sti5 v 99 uk I would expect both engines to make similar power when fully modified with big turbo's etc

It is!

The words "very conservative" was used by the tuner that mapped it originally in 03 for UK Fuel, when the car was checked over by him prior to me purchasing it last month. As far as I am concerned, the car is more or less standard apart from a first generation sports cat exhaust and conservative re-map for UK fuel.

All I can add is that if that is conservative I can't wait until it is mapped again to it's full potential.

I have seen this car in action along side the STi in question. I thought the STi was quick, so this Spec C is obviously going to be a rapid machine no matter what work he has done further. It sounds superb with the equal length headers.

in standard form the spec'c' is an AWESOME car........ ask MOST of the modded STI's in essex now for the downpipe and re-map to see wot we can achieve... cant wait.....

I thought you were having more fun in a Sport these days

I have just bought a 04 JDM STI - not c-spec but has all the uprated internals and twin-scroll etc. It's got a full milltek sports cat system and remap and the performance difference between that and a uk spec is very large

I had my Spec C 2003 model on WRC's rolling road. It produced 306bhp, 335ft/lb torque. The only mod it has is a TSL ECU Tek remap for UK fuel. Not bad for a standard car with the standard exhaust, air filter etc.

they corner rather well too.....

have you visited www.spec-c.co.uk still rather quiet tho but hopefully should liven up......
