Quote from: twiglett on January 30, 2020, 09:20Have you thought about nankang aR1's?
Lots of people say they are a brilliant compromise between a slick and a semi slick tyre because they are basically a cut slick.

Yeah i have a friend who runs them on a civic ep3 trackcar and they do seem like good tyres once there up to temp its a consideration, but for me the dunlop or advans are the way to go from what i have seen.

@tommyzoom99 very interesting in your thoughts on the staggered v square set up on track. Managed to source a set of 195 50 15 equivalent size slicks but not sure how they'd work out over my current AR1's 195 front 225 rear.

What staggered sizes were you running before going square?

@JB21 before i went to 15x8 all round, i ran 15x7 front and 16x8 rear. with 205 front and 225 rear.

i think the major benefit was dropping down from 16s at the back to 15s, the old wheels where rota which where heavy and we lowered the rear a bit, so there is multiple things all going on that contributed to the effect that we feel.

if you have 15s all round with just a tyre stagger i imagine the effect of going square just on tyres alone will be much less than what i have experienced with my setup change, all be it there should be some improvement.

This does all depend on your driving style and what you want from the car when on track/road, some people might make the changes i made and not like it for example, so its pretty subjective

but the car is now definitely a few seconds faster round oulton park our local track.

Thanks mate. Think i'm going to give the square set up a go. Can adjust suspension, ARB's, camber and toe if its not to my liking i.e to much oversteer.

Love the build Tommy. Did your mapper supply and fit the ecu too, so drive in/drive out scenario? I'm the same as you - more than happy to do anything mechanically but having not done anything like that I wouldn't know where to start!

Also, have you thought about ducting the rad from the bumper up through the bonnet? Seen it on a fair few builds on mr2s and other cars - much better cooling efficiency and, theoretically, adds front downforce (upflow of air etc). That and a full flat floor/diffuser would probably make a decent improvement of corner speed on track.

See this post for an idea of what I mean...

Hi lower

the mapper didnt supply the ECU we got it through a friend we know in the automotive business for a bit of a discount. i then had it wired in by another friend in the automotive business who i trust who is very good a this sort of thing as i didnt want the install all messy with a rats nest type deal going on. then it was mapped by another person first time round then we had it mapped again when we added extra mods.

That mr2 in that link is so nice! yeah we have talked about doing a duct for the front but just not got round to it, maybe if i didn't destroy the old car and have to spend a year rebuilding a new one i might of had this done and theirs always something going on with the new car, a full flat floor and diffuser would be nice a well maybe one day there is a pretty long list of things to do on it at them moment

cheers tommy

Ah ok, fair enough. Would you say it's worth the work to change from MAF to MAP (and intake temp?). I guess having the flexibility of what you do with the intake is pretty good. Also did you say you've removed o2 sensor(s)?

@lower

If your not bothered about fuel then it's worth it 😂 it's not really any more work if your going standalone ecu, it's probably less work to run without them, and it does give you options for the intake for sure and make the engine bay much tidier without all that junk in there. Yeah we don't run maf or o2 as it's not a daily it's not really a issue, for me it was worth running without but really depends on what you use the car for tbh.

Cheers Tommy

My old trackcar had a full flat floor, rear diffuser, fuel cell in the front and a ducted radiator out of the bonnet.
By far the best handling car I have ever driven.
Wish I hadn't sold it.

HI all, hope your all well.

finally out of lockdown and allowed on trackdays again. Went to cadwell park for the first time with a few friends last week, which was ace, such a good track defo wanna go back again.

Quote from: tommyzoom99 on January 22, 2020, 13:33i have to say going from a staggered setup to square has made the world of difference, the car is much faster around a lap and can carry vastly more corner speed and just handles better all round definitely made the right choice.

Interesting stuff! Don't suppose you have any vids using the square setup?

@tommyzoom99 what is your fuel cut set at with the stage 3 cams?

Stage3? When did you go Stage3?? 
And I thought you had gone bigger than 79.5mm bore? 
I've got your car totally wrong

I think I read that he went with stage 3 and 12:1 ratio. Also at 185 hp/ 150 lbf, reaching 2zz numbers.

More torque than 2zz @ 150 ft-lb.

Just read this from the beginning, great thread and great car! Inspiration for the rest of us, especially going through the full reshell. Top stuff.

Hi All

We run stage 2 crower cams not stage 3, the rev limit is 7k for the soft limit, and 7250 for the hard limit

the bore is 79.5mm 0.5mm bigger than stock to fit the 12:1 pistons

cheers mate, been through alot with this car

Hi All

Done a fair few trackdays since lockdown went back to Anglesey and Oulton park twice a few weeks back which was great, few pics below of Anglesey

Those are pretty good trackday photos, particularly like that first one.

Super job, thank you!

HI All

well im pleased to say me and tom will be adding another black mr2 to the family this time 2zz. I'll get some pics up soon with its new stable mate when we collect it. going to be interesting to see how it stacks up to our original one.

very happy with the whole situation.

cheers tommy

Well done Tommy 

Perfect pair of 2s
