Chronicles of a 13BT swap......

I think it made 260 at 0.5bar (with the wastegate stuck open) but he\'s got a half-bridge iirc. Probably could make 300 with the right support but we\'ll see.

[Ian65]

that\'ll be a handful then... have you considered a roll cage!

[captainbizzaro]

I would cage it if I was planning on doing a lot of track days but I just don\'t get the time so apart from some enthusiastic bracing I don\'t think I will. A cage with a non-helmeted head in my opinion is nigh on just as dangerous.

Agreed. I used to do a bit of Rallying and had a few rollovers as a navigator (as a driver you get to hold onto the steering wheel...) and the cage was an absolute menace - twice I smashed crash helmets on the damn things. They were a benefit in stiffening up the bodyshells (which improved the handling no end) and at stopping side impact intrusons when you had a tree trying to get inside with you, but without a crash helmet they were a real problem, not a good thing at all. I had 14 rollover / end over end incidents, most without rollover bars, and would be hard pressed to say that the cage gave (or would have given...) significant benefit in any of them.

Yeah I agree, plus I really can\'t be arsed with the gymnastics of getting in and out of a caged car.

So this evening after following some advice from Prof in the 2nd gen arena I reinstated the front pulleys. In my eagerness to take stuff apart I forgot to make any reference marks so was dreading having to work out where TDC was through the spark plug hole etc-but luckily the holes only line up one way so that bit was easy peasy, then once that was on and TDC was established I fitted the CAS into the 12AT front cover, which also went nice and smoothly.

Tried to fit the clutch too but I don\'t have the right bolts for the flywheel and they aren\'t the pitch of the regular 8mm SS bolts I have in abundance so if anyone reading has six of these that would be great.:Thumbs-up

Hmmmm,i\'ve read a few posts about rollcages for street use,the general consensus is it hurts your head without a helmet!So not really worth it.
ta stu..

[syebba]

I have to say captain,if your engine does kick out 260>300hp,it would be even quicker if u lightened it up!
But again for street use,is it worth considering,probably not.

he could load it full of bricks and it\'d still tear up the street with that kind of power!

Can\'t wait to see and hear it....

Yes it\'d still shift & the bricks would help with traction!
 
Main problem i see,is getting that power down on the tarmac.

[TiddlesRX7]

I also require an S5 throttle body so if you have one then speak up!

I have 2. One on my car and one on my blown motor. Infact the blown motor has prtty much everything on it still.

I did quite a bit of roll cage investigation when looking into one for my mx5.

The conclusion I came to was that for road use it was only worth doing if you were gonna have a proper bucket seat, one of the ones that came up right round the side of your head, 5 point harness and used the proper spec roll cage padding. Like everyones said because otherwise a relatively minor accident can cause sever head injuries as you hit in on the cage.

Still with a 70s design, I presume the 1st gens don\'t crash too well and I am quite tempted to cage mine at some stage.....

You\'re right Stu, even the standard car with 115bhp spins its wheels and slides pretty easily in the wet and sometimes in the dry.

Putting the power down will be a challenge.
My Jag put\'s out 400bhp and the traction control is always on as a default and often kicks in just driving normally. I have to manually select it \'off\' and then the car becomes a right handfull... terrifying in the wet, ( so I always leave it switched on.)
No such technology though on a 1st gen.

It doesn\'t matter how much power you\'ve got if you can\'t get it down on the road.
It\'ll be great fun trying though!

When I had 260@wheels I did not have that much of a problem with traction. Just make sure you get good tyres (Toyo 888, Yokohama A048, ect) and don\'t just stamp on the throttle coming out of corners in low gears and you will be fine. Make sure your awake when driving in the wet though.

I have to be very carefull when I get mine back with 500+@wheels. Will be a challenge

I\'ll PM you...

Pete-I don\'t suppose Jon gave you the six bolts for attaching the clutch house too the flywheel did he? No probs if not, just thought I\'d ask before hunting some down.

[Christopher]

Afraid not. I should be going up there end on Jan, so I will ask if he still has them if you want.
