I need/want to be able to adjust camber/castor at the track. Unless you guys have a wheel alignment machine you care to loan me? Who makes those bush kits warren? I've seen that noltec do an adjustable one for the rear.. ? Dave

Guys, Have any of you guys had the strut top mounts cut off and custom ones (with some form of adjustment) welded on? I'm contemplating getting Fabraications or trikfab to have a crack at it. Comments? Dave

Guys, What have you guys done re strut braces? I'm chasing some up but obviously whiteline don't do them for the zed (not that I can see). I do remember someone selling them at the nationals but didn't check to see who it was. Any pointers? Thanks, Dave

Toecutter, You can add a turbo to any setup. Bloke in SA (BensDR30 on ozdat forum) is running 7psi quite happily through his standard L28. F54/P90 block with flat top pistons gives you 8.4:1 compression vs with turbo/early-L28 dished pistons: 7.38:1 compression. The turbo 280zx was never sold here, hence all L28ET engines are imports I believe. Stand to be corrected though. In the USA they DID sell the turbo 280zx so they're a lot easier to come by over there. Depends how much power you are after and how much effort you are willing to put in. If you're going to rebuild it anyway, I don't see why you couldn't just run a normal L28 block and head with forged pistons to get the desired compression. I got my L28ET in a private sale (didn't know it was F54/P90 at the time) so I just got lucky there. Dave

Guys, I just drove my turbo L28 for the first time yesterday. Haven't tuned it at all yet so its running very rich (10.2:1 on boost). A little bit of background, was running an SC14 supercharger on the L28 (F54/P90 L28ET engine) producing a whopping 5psi boost in draw through carby setup. As I drove it yesterday is as I mentioned in introduction: autronic, gt35r, front mount etc. Now I've never driven a 3.1 stroker L but some general N/A vs turbo comments are warranted here I suppose: You need more details to make any form of comparisons. A 3.1L with a standard cam isn't going to move quicker than a turbo L28 with 20psi, nor is a mild boost L28 (like one on 5psi) going to beat an 3.1L. Horses for courses. If you are happy with carbs and are chasing a realistic power figure (300-350hp say) then there is no reason an 3.1L wouldn't do wonders. A properly built turbo L28 however will have much more outright potential. FYI my L28 with GT35R is about as laggy as a standard FJ20. Dave
