WTB L28 engine
Greetings
So the engine i had lined up to buy ( not through the club ) may no longer be for sale so i am looking for an L28 as the base for my L30 build. Any help would be great cheers.

If you have trouble finding a L28 - just sleeve a L26
Yes it is a shame you can't get new heads still like others that kiwi cylinder head makes and export. Now if you were going to the trouble of getting a place like that to cast up a new head - I think it would be better to get them to make a replica of the FIA cross flow head - as that was FIA approved now that would have some value...but that is off topic....mike260z wrote:Good idea - i did however get told that my L26 has the wrong head , as in not the right one for tuning.

If your head was off a 260c it might be a E30 or E88. The E88 is sim to the N42 (N42 is the L28 head, as in the P90) the issues with the E88 heads is
1. The age - most have gone though a number of heat cycles = soft
2. The have small valves = more work (but then for performance even an N42 or P90 will be worked in this area too)
Now as you are going L30 anyway you want a head to breath to match that bottom end and if you want good strong power get ready to drop some good coin on the head/cam/valves and labour cost to do it right - between $2.5 - 3K I would say (but that does depend on the goals of the car - you can do a $1.5 - 2K and make a good strong head for a very very strong road car
Do you want the car to run on pump gas? That will limit your CR to around 10.5:1 tops and around 210-230hp at the wheels if every thing is done correctly and matches ie headers, carbs/EFI etc (A worked race engine should yield a lot more )
Try calling Blair engine suppliers (google) they sometimes have L28 engines not cheap but it will be a good strong L28 that has been stored inside a warehouse.
Thanks for all the helpful info mate. I think from what Anthony said my head is an E88 and not worth working on. The goal i have for the build is an engine that makes around 200 - 230hp at the wheels and runs on pump gas. That should be plenty to light a fire under the 260Z. I dont want huge power and breakages. The main reason i am building it as my car came with triple 44mm Mikunis and a Nismo exhaust and headers so i am building an engine to fit my accessories. I dont want to part with the carbs and they are wasted on the current engine. I want to keep the L26 in case there are issues with the other engine and so i can keep driving the car until just before i drop the new engine in.

I think that may belong to the club member i have just got a crank off perhaps , i am wanting to run an N/A engine for my big carbs and also that engine is a bit more powerful than the one im wanting to build but thanks for the heads up.badhabit wrote:there is a turbo 3Ltr on trademe, LD28 crank etc etc - seemed like a good price too

I have a L28 N42 block minus manifolds which ran ok but was low on power so perfect for rebuild. $400, drive down to Tauranga and pick it up. Planing to remove it from car veryu shortly, probably this weekend. Have to check which head it has.
All Nissans are racecars.
Cool sounds great - Sold Just get back to me about which head it has. I am off to the South island next week for work but if you PM your account details i can bank some cash to secure it till i can come get it. Man i can just imagine the Prius trying to haul that lot over the Kaimais haha

I normally come through Matamata way - i just like to make jokes about my work Prius whenever i canZMAD wrote:Cool no problems. Get back to ya. The Kaimais is the long way to Tauranga. Have always gone via Paeroa/Waihi.
Thanks for the page on the L6 heads - some great info there
