I have a L28ET exhaust manifold from a 83 280ZX Turbo, unit was made of three pieces, and put together with two bellows couplers. Here is a picture of the manifold in question, found on mrjeffzx xtreme Nissan 280zx Turbo page: https://www.angelfire.com/extreme/280zxt/images1/Euromanifold.jpg One of the bellows has a crack in it and needs to be replaced or if possible repaired. I don’t think it would be possible to weld it, at least not with my welding skills. I tried finding this part on RockAuto, eBay, FAST, Nissan4u and a couple if other sites without any luck. Not even a part number Therefor I thought I should try asking here for help. Maybe there are alternative ways of fixing this. Any suggestions are welcome. I have attached a picture of the damage (The white stuff is exhaust paste since I first thought it leaked around the clamps) Thanks...

I have a P90a head (Solid lifters) I want to upgrade with larger valves I have found out that I can increase the size by 1mm on the inlet valve and 1,5mm on the exhaust valve without having to change the valve seats. So the question is where can I by oversize valves ? UPDATE: I have found these valves for my engine: http://datsunspirit.com/shop/dsi-big-valves/ But the stem length is to long for my use, needs to be original length. Other than that they would have been perfect. and http://www.ferrea.com Wish thay had 1,5mm exh. valves Anyplase else that I should check out ?

I have a P90a (Non Hydr) that i'm planning on oppgrade with new larger stainless steel valves and I wonder how large valves can I use before the valve seats needs to be replaced ? And is it necesarry to do anyting with the valve guides to use stainless steel valves ? Thanks.

Waking up an old thread, but I have a question about valves on a p90 head. I was wondering if you need to do change valve guides if you switch from stock to stainless SI valves. I'm thinking about friction problems due to heat expansion of different metals.

Also looking for a PS2000 base map for a L28ET engine. A map and info on the setup of the engine it is programed against will give some valuable info on understanding how the mapping process works. The most important info is: fuel pressure (idle), injector size, engine volume etc.

PM sendt to VQS13LUIS and Chemicalblue

Is there anyone here who have a map for the L28ET engine they can share with me? It can be for the Haltech E8, E11, PS1000 or PS2000 ECU It would have been nice to have a map for this engine to get me started. It does not mater what you have done to your engine as long as you tell me.
