Sorry mike i ment the coils on the front shocks but thanks for that info too. Good to know.

Of course, what the hell was I thinking????

 

The Z car coils are a much larger diameter and will NOT fit up inside the 510's strut towers. When swapping to zx struts trim the bottom spring mount off the zx strut, grind away the old weld until smooth, and use your 510 coil (possibly suitably trimmed to increase the spring rate but not to set the ride height) and 510 spring perch. Support the spring perch with 2" split collars from Fastenall about $25 CDN. The ride height is set with the split collars.

 

The 510 stock coil spring rate is 89 lb/in. My 710 is about 100. I worked out the spring rate and removed a coil and a half to increase it by 50%. There are mathematical formulas for working out how much to cut. If you go this route get me several measurements and I can work out how many coils to remove. I like 150 lb/in you may like more so don't just hack coils off because once cut it can't be put back on. Doing it this way gives you ZX struts and adjustable ride height for under $30. Assuming you have an angle grinder and metal cutting blade.

 

When you dismantle the zx struts you might find that they have the original oil filled dampers still in them. This is a good thing as you can dump out the old watery thin hydraulic oil and replace with something thicker. I used Belray 20W motorcycle front fork oil. Thicker fluid is harder to push through the strut valves and firms up the dampening. Add another $17 Which is way cheaper than replacing with strut inserts @ $80 (each I think)

Thats awsome :-D

Im guessing the top of the strut perch needs to be swiched aswell....

 

Know i was told once (i hope im remembering it right) that i can port my head and put the l28 flat top piston in and my motor would be prity good. Is that right?

[flatcat19]

L28 does have a computer. Correct.

L28 does not have carbs.

 

His current car does have carbs. But no computer.

[jimmy billy]

Correct fatcat.

[flatcat19]

*flat. Though I am a bit heavier.

[jimmy billy]

Oh shit sorry buds lol

[jimmy billy]

 

 

 

Well here she is and i found out its a 81 not a 83 like budy had on the add.

 

Runs awsome and everything works but the turning signals.

[Sealik]

What head is on the L28?

[jimmy billy]

I beleave the p79. The turboed mode had the p90. I have to look and see what it is still

[jimmy billy]

I think i saw N42 but the write up sead only about the N47 head.

[jimmy billy]

Ok read up on it and the N42 is the same as the N47 and they say if you put the n42 or 47 head on a f54 flat top block you get upwards of 10 on the compresion. Now my block says 595. So i gotta read some more to see which one it is

[jimmy billy]

Ok i have a f54 block
