I've never had any problems like that on mine, maybe they measure the power differently over there?

Thats pretty interesting!

I haven't bothered with any as i dont have the engine in the front, but after seeing that i may do!

As surely that effects handling

probably do more good to stop the floor flexing. The brace bars dont really offer much triangulation if you think about it they more or less fit to the same area as the top mounts so it all pivots around that point.

yeah but surely because they are fixing the front of the frame to the bulkhead, this will majorly reduce/stop the movement?

when was he last time you saw a clubby with Mk1 door hinges?

I Recon that is a Mk3 rubber mounted subframe.

valid point but I still recon the only way you get that much movement is with a rubber mount frame

nope it is an aus clubby so it will have a solid mounted mk1 style subframe. I know as i have one.

Something wrong there..?

Soon he'll have nice fatigue fractures where his rear subframe mounts used to be attached.

Not good...!

my car did the same on the rollers.. if any of you are familiar with most frames for alien engines you will know that the main force from the tie rods is transmitted to the car via 2 bars which run (and usually bend as a result) under the sump and gearbox. these are under a tremendous amount of load under acceleration and breaking, in the first incarnation of my frame, i found some fatigue fractures in one of my lower bars, right at the centre of the angle cut where it bent up after coming under the sump. indicating it had been bending. 2nd incarnation of the frame i heavily gusseted and braced the bends in the lower rails, and suffered no fractures since. however, when the car was on the rollers you could see the same kind of flex. the tie-rods were pushing forwards and lifting the nose of the frame up. 3rd incarnation of the frame and i have added a second set of bars from the tie rods straight back to the floor pan with no bends, whilst keeping the original bars, for a belt and braces approach. less bending and car pulls straighter under throttle :) .. isn't there a video of MOT's front end doing the same thing on the rollers?? the same video where there was a wee fire?

its a 4efte turbo from a toyota starlet,with home made subframe based on a mini subby, all signed off and certified by an engineer as all engine conversions have to be in Aus.

this doesnt just happen to home brew frames! solid mount a late frame and it just bolts to the flat heelboard.(the frame in the vid obviously bolts to a different place, i was just suggesting a reason for its flexing) iv suffered signs of fractures here(on the heelboard) on a standard 998 mini with a solid frame like i say the video of MOT had the front end lifting up under throttle..

The rear mounting points on the early (non-rubber) are certainly at a much stronger point (re-inforced angle change between healboard and floor).

That's why I'm using the earlier front subframe on my build...

The later (rubber) ones are rear mounted on a flat and flexible part of the "floor".

Hi all, I know this car pretty well and it has been sold recently, it actually made 201hp at the wheels just before he sold it.

her is a big part of the build up.

Well,

Had a good scan through, and theres some nice work gone into that, a few bloopers to though, like the wire grill over the turbo inlet, but that was only temporary.


the subby looks like it is the early mk1 style from the pic on page 12. To me from the pics on the 1st page it looks like there isnt anywhere near enough triangulation (any!??) to the front tie bar area to stop the frame losenging.

i think the movement is more to do with the fact that the engine is solid mounted than the subby design.

but i built some bars into my subby so hopefully i wont have the same problem


no longer a series, but still 1.3 turbo.
