Hi all. Thought it was about time I added some of my car after perving over the others in this section.

Moody shot, taken by a fellow PH'er at an Ace Cafe meet:



One from a while back at Bedford Autodrome:



Once from the Toyota Sprint Series last year:



The Pro Alloy FMIC core I fitted to replace the Charge Cooler:



Dyno print out comparing the stock turbo and Blitz ECU with a PFC and Turbo Technics hybrid turbo:

And finally a picture of it on its road wheels:



Cheers all!

Cheers chaps!

We have had it for 3 years now (35k miles in our hands) and had no mechanical failures. It has been to the 'ring twice, France, many track days, the Toyota Sprint Series and a couple of club based track weekends without any problems.

The only thing that was damaged was the water to air charge cooler radiator on the last trip to the 'ring. A lorry had a blow out that caused its mud gaurd to shatter and puncture it. I blocked it up with chewing gum on the way home laugh and replaced it with the FMIC when I got back.

Discs and pads are quite expensive (it has 315mm discs all round with 4 pot fronts and 2 pot rears) but quite hard wearing, if you choose the right compound. I use Toyota discs which are about £300 all round. EBC yellows last well and are about £130 all round, Carbotech XP8's are even better at around £260 all round.

HTH biggrin

The stickers were a requirement of the Sprint Series, but they are off now, new series starts at the end of March which will be great!

Thanks for the comments on the FMIC core, it actually helped me make more than 20bhp over the Charge Cooler running the same boost levels. Once I had fitted the FMIC I made no changes at all to the boost controller yet acheived exactly the same boost level at the inlet manifold at the same RPM's as before so it seems to flow well enough thanks wink

Also, the CC is very good for road use but really out of its depth on track. Despite lots of lagging and heat management the intake temps would increase after the first session and never recover for the rest of the day. Whereas the FMIC allows constant intake temps albeit with ugly pipe work compared to the stock CC.

TBH it surprised me a bit too mate, but it is an expensive , british made core so it should flow well. The CC is fine for road use but if you up the boost and run it on track you'll see 50 degree+ charge temps all day. The pre rad is quite small but the ecu control of the pump is very clever, only running when you are on boost.

I think the reason for making more power on the FMIC is that the stadard ECU won't retard the ignition timing so much which costs you power and torque.

If you think of a rolling road day, you turn up after a long run, hot engine heat soaks the CC and then you go on a dyno with a fan and the intake temps have soared. Whereas with the FMIC, the core is out of the engine bay and cool as soon as you put some boost through it.

There are ways I am sure of making the CC more efficient but it has added complication (witness the hole in the pre rad on the way back from the 'ring), water pump failures, coolant leaks etc. Plus the FMIC set up is lighter (the car is extensivly stripped and it makes more power, more consistantly.

Mmmmm, Lancia cloud9

I have had the pleasure in going out on track in a Integrale and back to back comparing it to the GT4 at Bedford Autodrome. Me and the guy that owned the Lancia both loved each others cars (it was like a Sega Rally day!) but you could see where things had moved on in terms of structural rigidity and dash ergnomics. Saying that, if I could have afforded to buy a decent Lancia, I would have! bow

The Sprint Series is for all Toyota's so there are MR2's, Supras, Aristo's etc on it too.

On track with a few simple changes to the suspension (Whiteline rear ARB, Tein Springs with KYB dampers and some camber plates on the front) its very good and still very useable on the road.

Plus with the prices what they are now, you should be able to pick a nice one up for £3500-4000 frown

Agreed, it is a real shame that Toyota have lost their way in recent times when it comes to high performance cars. Back in the mid 90's you had a choice of Supra, MR2 and GT4, all of which are great fun cars to drive and plenty quick.

As a track/weekend warrior car I think its tough to beat. Good chassis, stiff shell, strong brakes, reasonable (for a jap car!) interior, strong engines and robust enough to take the abuse of driving on track. Plus, when it rains (which in the UK is a fairly regular occurance rolleyes ), you have great security, traction and fun. biggrin

I can't see us replacing it for a long time, the Mrs loves driving it too and has given me the thumbs up to do a forged rebuild with a 5SFE crank shaft which should give me 2150cc and the ability to up the boost. Good times. cool
