Have you tried running w/o the MSD box?

I have searched and have not seen where anyone has stated that they have utilized all of the fuel pump relays and efi relay for their MS install on a factory turbo car. Wondering if this is overkill or not needed.

I for one appreciate what Derek has accomplished, and if I had the bucks would buy it, but I really can't see it ever becoming a commodity at commodity pricing. But then, I have an automatic that doesn't like high rpm and am limited by that to 4-500 HP with a turbo - and my stock head works for that.

Good to know I was close. Glad you got what you wanted!

Forgot you have the stroker when estimating spool - sounds like you got what you wanted!

zuhow: It appears that you think I'm being a DICK for having to point out TWICE that you failed to provide needed information. I think you'd better look at yourself in the mirror wearing your big boy pants.

Getting enough info is like pulling teeth for some reason...

You ask a question without telling us what equipment you are running and expect an answer?

Hi folks; Looking for high back bucket seats for my 280ZX. Thanks...

Then you should be golden...

You may not GET to 6k with any power...

Top end will be choked off a bit. Your power will be in the low to midrange rpms.

It'll be choked off a bit and start to spool around 2800 with full spool around 3200(estimated). Stage III turbine is like a 68 mm inducer and 62.35 mm exducer. The compressor wheel you are describing is awfully close to the 50 trim T04E and is a good match for the engine if not turning over 6k.

I don't think you have your trim specs right. Trims are usually whole numbers. The 74.2 just so happens to be the measure of one particular turbo e wheel's inducer diameter - and it is for a GT3076 turbo. A 50 trim compressor section is one of the just right compressors for our size engines in the normal journal T3/T4 series turbos. If you want lower spool the the T350 turbine (stage III) would be perfect. If you want more top end power then go with a stage V turbine.
