What Plug Gap Would You Recomend On That Heat Range Plug?

I am running an n42 head on a 54 block bored .40 over with dished pistons. Stock turbo at about 8 lbs. timing at 20btdc. on 93 octain gas . I have no pings or knocks.I love this setup because of the off boost tourque. I get full boost at 2300 rpm. from the higher compession. I have great on boost power and get a surge at 5000 to 6500.I am using the stock n/a cam from a stock 76 n42 head.I recently drove through the mountains fron nc. to ky. and got 26.5 mpg at 85 mph.Using the engine calculator I have about 8.4 to 8.5 compression. i

base timing on an 83 turbo is 24 btdc. 81 and 82 had 20 btdc. I have an 83 and the response between 20 and 24 is very noticeable.fyi

Thanks guys , I got it running right. It was the old good conrction today and bad tomarrow

Sorry, its an 83 turbo. It will rev to about 4k then go flat. It seems like it runs out of fuel.I changed the fuel filter and checked the timing.ajusted the afm. All electrical connecvtions seem good. All that happed from good to bad was the o2 wire. I thought that the o2 would mostly effect the mid range.I will recheck my soddering. Any other suggestions?

Help!! I cut the wire to my o2 and soddered it back together and the motor goes flat when the boost builds and will not rev out.Can an o2 senser have this muth effect? Is there any reason you can't sodder one?Its the only thing that happened after i turned the motor off the prior day.ANY CLUES?

Are those 14s or 15s?

If you put a n/a auto in a turbo , how does the trans handle the positive boost? What is likely to happen? Any one know or have tried?

Does any one know the stock converters stall speed on the stock n/a and turbo auto trans? Can you put a n/a converter in a turbo auto? I have an n42 head on a f54 block and have about 8.5:1 compression. I want to run a n/a converter in a tubo auto. What do you think?

I have the problem of only super hot. no fresh or cold air.Is mine stuck open/

Check the air regulator and the temp senders. these can make the car rich.

Will the maxima trans mount just bolt into a turbo zx? Is there a model or year that can use the turbo drive shaft? What was the stall speed of the maxima converter and haw was it with the turbo motor? What ratio diff did you use? I was considering going down to a 3:7?

I am closer, I just moved to Hudson , just outside Hickory.I found an almost new dizy and am getting it sat. I have a brand new battry in the car so I don't think it is that.I hope the dizzy has the ignighter with it.

I can hear it in the exhaust, see it on the tach. and it only shows on the light when engine is hot.So , not my light sucking. that would be too easy.How about a bad dizy. It has 150k on it.

new battry.can a coil start breaking down after it gets hot without completely failing?it runs great until it has been running for 5 min. or so. then the miss at idle starts and the fireing gets erradic when you watch the timing light.
