L28E questions

[mtcookson]

So I read somewhere that the stock compression on an L28E is 8.8:1 which is not too bad for boost. How well would this engine handle with boost compared to the L28ET? I'm thinking of just doing the basics for a bit more power over stock until I can setup a better engine (not saying this engine is bad or anything ). The basics I'm thinking of are:

 

injectors

ET exhaust manifold

small t3 turbo similar to what came on the Z31

upgraded fuel pump since i will definitely need it down the road

ecu from turbo 280 (will this work on the 280Z?)

various neccesary gauges (boost, maybe fuel pressure, dunno, etc...)

 

I'm pretty much a full newb to the 280Z's but not to Nissans (check out my cardomain) but please don't be too harsh on me.

Do a search and you'll find it's been discussed at length. I am running 8.8:1 flattop pistons in an L28ET. I am breaking in the motor at 8 psi boost and so far no problems at all. The P79 280ZX flattop pistons are very robust, and have the same thickness rings and ringlands as the turbo piston.

 

I am monitoring A/F ratios very carefully, and have the static timing conservatively set at 19 degrees. I use a surge tank to prevent deadly fuel starvation. I figure I can run 10-11 psi intercooled before I start to lean out. Beyond 10 psi, I think I will need programmable EFI, and bigger injectors, and probably a better intercooler, especially in this Arizona heat.

 

Why do you want a smaller turbo?

Sounds good. I'll search around a bit and see what I can find.

 

I wasn't sure if the 280 had a smaller turbo than the Z so I just threw out a turbocharger i knew of (even though it is really small).

 

In the end, I'm wanting to have either a VG30ET or a VG30DETT with a T3/60-1 and the whole works. That'll be a while down the road though.

 

Thanks for you help!
