im still here, sometimes. I still got miley and still the original owner. She has come a long way. went from 517 whp on 94 and meth to 596 whp on e30, and now on e35 on a s258 turbo she made 680whp. if anyone still exist and wants to see a sheet and video let me know lol

 

Good work Tom!

 

680 is a strong number, what's the details on that ?

 

shoooooo 680?! golly! we need pics, dyno, all that stuff! nice job!

 

X2. Mine has been running great, but the rust is starting to do some serious damage. Been debating if I want to spend the money for that or let it go until it's too much. Closing in on 300K kms.

 

Sweet tom. A few of us still haunting here clearly haha. Car has been gone couple years now moved on to other things.
nice to see she’s still making more jam after all these years. Never thought we’d get a re dyno hah. Where did you dyno?

 

Thanks man . Hey Kev , u still in the cobalt game ? What u been up to? Still tuning?

 

So it is alive here lol I'll post vid and sheet later.

 

Basically the same setup I had for past 7ish years, except I went to E35 fuel and I went from s257 to s258 turbo. The 258 dynoed 84 more hp on the exact same tune. Or don't u know what my setup was and is? Lol

 

Dynod at motion. He is updating his system this fall so I'm gonna go back when he does and see if u can break 700whp. I got a couple of tricks I added to get the extra 20 HP lol unfortunately said tricks makes Miley uncomfortable at wot and it maxes out the .63 AR on the turbo. Motions rpm pickup was broken so I didn't get a tq number unfortunately, but it should be around 525wtq

 

Mine is almost at 200k and relatively rust free., needs some paint but rust hasn't been much of an issue , just back fender area that I fixed myself.

 

Should I know what it is ?

 

probably not lol i don't recognize the user name so u probably weren't around when i did the build.

She made a 50 hp dip there, think i fixed it, will see next dyno. also the 3 pulls i did, first one was car as i drive it, made 680, second pull was with spraying meth....car hated it and broke up up top, made 650 on that one. the last one was with a different set of cam tables i was testting, made 670 with that one. so first one was the winner.

 

 

Thanks, yea I found more info searching your name on the forum.

Was more interested as to what block, but I see you're using the better closed style of block. I've been trying to, find one locally myself, but they seem difficult to get hold of. Good to hear it's been making power though for quite some time

 

Im trying to find a spare. Iv resorted to looking for Buicks with it for cheap or parting out. But market place is insane , places who have the engine want like 2500 for them out of wrecked cars.

 

There have been a few in the UK for sale, used engines. Although it's also not 100% clear whether both A20 NFT and NHT are the same block. From what I see it's the NFT I'd want, not the NHT. But even engines in England etc....I'm in Northern Ireland, so it's a nightmare as nobody will ship an engine here. I'd have to go over to collect, which then adds huge cost and inconvenience.

I'm just running an LSJ/B207 type at the minute, and have a spare block for that. Rather than build/sleeve one of those, I'd much prefer a factory "closed" deck version. But no hurry on it.

 

Well I have my car going again finally.

 

😅 How long was it down? Like 10 years ?

 

5 it's been on the road a little but now

 

Weren't u making a closed deck block? Did u get that done and In her ?
