HI all , I was directed here form SWCC car club as I have purchased a 300zx Convertable 3.0ltr non trbo Auto . Now 1stly I hate autos and non turbos well frankly is no good so I am modifying it as much as poss, looking for guidance and help in regards to the follwoing mods that I am undertaking.

Auto to manual conversion (bought all the stuff )

Lowerng compresion on engine and adding twin turbos.

Aluminiam Fly wheel ,

NOS 11lb Botttle twin injection 25 bhp with controler

Uprated cross drilled brakes with SS Piping

18 inch rims

ACT 550LB performance clutch

Diridium Plugs

HKS Cool Induction kit.

leather reupholster kit (not that this makes any diff to performnce)

ECU being reprogrammed in america on the mods im undertaking.

 

NO wall these changes , I was told to speak to a person called Mark as he has done this before or is a bit of an expert in his field. Now I have to say I dont have a clue I got a friend mechanic who in my eyes is teh ballocks (Great) but Im hoping that perhaps you can shed any problems I will be facing befpre I actually start to fit all the stuff as I have purchased Everything but have not started the work yet. I would really apprectiate if any one has info for me before I start work and could they email em to ) as I have not got to grips quite yet with pistng on this site ).

Thanks

his name is mark and his id on here is 'Topless'

I wouldn't bother fitting turbo's as there's lots more stuff that's different and it'll cost you an absolute fortune.

You could probably buy a rusty TT Z and swap the engine, ECU etc for a lot less.

I think this is what Topless did.

 

You'd be better getting the ECU done here as they use different octane fuel in the U.S...

Z1 's website in the states has some good tech write ups on this, not got the web address here at work, but im sure someone will post it!! :)

See!! :D

Already bought all the stuff so to late to go and buy and engine ) , full steam ahead, getting the work doen cheap though , and the guys in America I have told what octane to calibrate it to .

 

Thanks

 

For all imput , new here , stuill trying to find my way around.

LOL You might wish you'd asked the questions BEFORE buying the stuff!

I hope you are getting it done VERY cheap as there's a LOT of work involved.

 

You could probably have picked up a TT engine for £500 to £1K and sold your N/A engine to get most of that back.

I'm not so sure the guys in the U.S will actually be able to reliably set up an ECU for you when all the bits you are using are going to be none standard and using different fuel.

You could have got the ECU sorted by a few of us on this forum for a few beers if it was a normal engine.

Are you getting cams, manifolds, turbo fittings, intercoolers and plumbing, fuel system, plenum etc? They are all different on a TT as are lots of other bits.

Not sure if the N/A pistons and rods are as tough as on the TT?

Sure you don't have to make it the same spec as a stock TT Z but i hope you aren't just expecting to bolt turbos on your N/A and it's done.

 

It's pretty easy to get a stock TT to 400 ish BHP but this conversion will be one hell of a job to do and I doubt you'll get near that figure without spending some serious cash.

 

I've replaced my engine done the auto to manual conversion and there are some massive costs that are easily overlooked and you'll have far more of them this way - gaskets, seals, fluids, machining parts etc.

 

All I can say is good luck and get working some overtime to pay for it.

 

Chris.
