Fitted new turbo`s less than a year ago now and they`ve started smoking.... been reading up on what could be wrong and questioning wether I`m getting too much oil to the turbo`s. It only smokes when it gets warm/hot and can be different from day to day. I put T25/28 on and fed them with braided houses complete with new banjos....now the only thing I can come up with is the size of the hole feeding oil through new banjo is bigger than the old one????? I`ve read quite a few articles and can only put it down to too much oil feed to the turbo......oil pressure is massive on the engine build. Any one had any similar problems???

The new Mot paper work is to say the least embarrasing when passing it to customers! We seem to apologise?? I`ve started to use a green and red pen when signing just so we can distinguish between them in the office!

hi, jack again, there is allot of threads about meets other than jae and what would be good is if we got a couple of us together and had a dyno then a blast on a track, obviously they would have to be near each other but would be good to see what people have got and then show it on the track. just my opinion:thumbup:

I`ve questioned the gear, it reads 4th on the sheet but now I`ve listened and watched the video it does sound like it was in 3rd. And yes I`ve quastioned whp to fwhp.... I can only summise that it was jumping around so much at higher rpm that it still achieved similar whp although fwhp was down??? Think Torque was still rising in run 2 compared to falling in run 1???

Tease!!! lol

You seem to know your stuff Jimmer?? Best way to set up my fuel system???:gunsmilie:

How much you looking for??? PM if you prefer!!

They did in 4th gear which is apperantly correct for a 2 wheel drive car!!!

Well I`m taking them as stock!!! No reason to believe dyno was out, my mates went before me in an evo 6 and scooby and ran 319 and 299.7!!!:shifty:

wiseco showing 2 piston size for tt m875 and m88.... 87.5mm and 88mm at a guess??

I`ll have to pick your brains Andy on your fuel setup, and if any of you guys have any suggestions that would be great. Question one: can I get rid of the fuel dampner and just feed the fuel rail from both sides, this would obviously be using a rising rate reg.:yes:

Engine as per my other thread, 87.5 Ross pistons, total seal rings, acl race bearings, standard rods and believe it or not standard injectors. T25/28 tubs, divorced down pipes, fmic. As the graphs show the boost is in to next week at nearly 2 bar / 28 psi,... I set the actuators at 14 psi with pump and gauge, but the guy from the rolling put me right explaining that the psi you set at comes out alot higher in operation (28psi)... he suggests to set at 9 psi and a boost controller to up the psi.... the reason for the kicking and fire spitting was down to the fuel been pushed back up into the injectors, so a possible tired fuel pump needs replacing / upgrading, a fuel pressure regulator and of course bigger injectors. I`m losing initial fuel pressure which in turn is slowing spool up time due slow pressure increase and of course reduced heat, which if I`ve read my info correct also has a bearing on spool up. I`m looking for a smoother and steeper curve to give me a quicker response and not just a wak in the back at 4500rpm... gets entertaining when it spins the wheels in 3rd at 80 mph.:w00t:

jack by the way, found it in york, needs new bumper, wing and bonnet, and just spray and atention, all interior is perfect and engine is to so will be fixed up and then see where we go from there! :D

good weekend, friday saw a new arival of a uk spec twin turbo manual with 64,000 on the clock just needs some TLC to bring her back to her former glory! also saturday sprung a few suprises with the original zed on a rolling road at Motorscope, got a great shock and where gobsmacked at the results :D pics of the new zed coming soon!

I`m running my oil pipes to atmosphere at moment but do wonder wether a catch tank in a sealed system would increase the crank case pressure an equal the pressure out between the bottom and top of the piston, putting less strain on the rings???

I`m just glad they saw it before yours Andy or else i`d have no chance! I like yours!! Swap?? lol!

Had a run up to the Nissan factory at Gateshead yesterday to watch the final round of the British Drift Championship. Bumped into Lee, (sorry Lee don`t know your user name), Lee was at JAE this year and managed to get his Zed to the Nissan factory. Any way to the point, while we were proding at the engines we were approached by the publisher of Total magazines and he asked if he could feature the cars in Total Nissan, which we obviously could not turn down. Many pictures and poses later, of the cars not the drivers, lol, the cars where captured!! We`ve both got to e-mail specs, pictures, history etc for a write up, which of course will include the mention of 300zx.co.uk, but feel it may be a potential for drumming up some new membership with a possible quarter page advert?? If Gary or any of the other moderaters could give a bit of feed back I could e-mail the editors details to whoever may require them and go from there?? Cheers Dave.

Well you know your all welcome to the seaside, got a friend with a couple of hotels who puts on an excellent breakfast (for you Andy) and is very accomadating with his Bar (for you Pablito) who I know would do it at excellent rates. A bucket and a hose, and then a cruise round the seafront??? And there is always the possibilitie of the use of the local road race circuit (I`d have to find out more about that, but I know it`s been done before). On another note, I`m definatley up for a track day or similar, these cars still have engineering way ahead of most modern cars and I for one would love to see what they`re capable of on the track!

:taz:

HI Will be leaving Scarborough at 4 P.M. on Friday, will be travelling A64, A1, M18, M1, A14 or alternatively A1 all the way down! Any one travel about same time who wants to run together give me a shout! Cheers, see all at weekend. Dave!

thanks for all the advice guys, its Jack by the way, we've decided the v8 is the way to go! new pics of the gt40 after we finally pulled it out of the old garage!!!:yes:

Been toying with the idea of putting the twin turbo engine in my long suffering gt40 replica??? It should be fitted with a ford 5.8l v8 (sat in shed). The car would weigh 1050kg with the v8 but i`m expecting it could weigh 1000kg with v6, with a good strong build i would be hoping for 500hp/tonne?? Would you give the thumbs up or down for this install???

Mines my first name and my other toy, a replica of 1966 ford gt40 which has been put on the back shelf since the z came along! 5.8l Ford Windsor v8 / 6 speed audi box / 40 inches high / 200+mph (i hope?)

wheres the meet, just striped the zed out to go racing at croft and they bloomin canceled it.
