I currently have a nx2000 with an avenir swap GTiR T28 turbo about ready to go in. However unlike yourself I do not have a lot of track experience and was wondering would it be a severe hindrance to my driver development to jump straight to a turbo NX instead of keeping it NA for another year. ( I have only 4 AutoX and 1 HPDE under my belt). While I have almost everything for the swap I don't want to rush it if it is going to be a stumbling block to my driving development. Then again many people start out with faster cars and seem to do fine.

I would only put the build off for one season so approx 3-5 hpde qnd 6-10 autox. Any longer and i will feel guilt leaving my nice avenir cold and unloved. Ps if i stay na my avenir has a crank scrapper and windage tray i could swap over to keep the engine more reliable.

What would you track junkies recommend? Thanks

A Turbo engine will probably trash your gearbox in short order. Better budjet for a B15 tranny swap as well!

Yeah, I have a spare b13 tranny and would run the amsoil you guys recommend but what is you take on driver development NA 140ish WHP vs a turbo @ 250WHP?

PS I will be running an setrab oil cooler, a ducted mishimoto rad.

as for the suspension etc:

I currently have agx/gc sleeves (350f/250r) with gc camber plates, st rear bar (will be buying front and rear progress bars before next spring), and front and rear strut bar (rear is triangulated) es bushings and whiteline castor bushings.

PS mike isn't a b15 gearer poorly for a turbo? I know most go with a P11 but no P11 are available in Canada (all were auto as far as I've been told) so if a B15 is ok that is great news.


I am also running 205/50/15 rs2 (not the best 140 UQTG tire but reasonable). I also have 14" v700 victos but want to wait to jump to r-comps as I heard they can cover up faults them bite you.

I also have 11.75 fastbrakes kit enroute (with the superlite calipers) which of course won't fit under the 14" wheels for the v700 but that's not a insurmountable obstacle.

The Agx and my spring rates are admittedly not ideal but it is a DD so I have to compromise.

The B13 tranny prob wont last past your first weekend. Not having the best ratios is better than having no ratios which you will have with a b13 tranny. Throw away the Mishimoto radiator and get a koyo.

Having a cheap car that can handle hour after hour on the track would be my recomendation. Track time is the most important thing imo.

 The last thing you need right now is engine upgrades.  You would be far better off spending money and time working on items that make the car more reliable, buying better tires and then getting as much seat time as possible. 

Newbies should be restricted from upgrading engines until every chassis and brake upgrade is made and they've spent the maximum amount of time possible in a year in the seat flogging the car on the track.  Only then should they think about more power. 

Spending all your time trying to sort out the car, worrying about whether or not it'll make it through the weekend tends to take the thrill out of  learning the craft.  Its a bummer. 

We have one car that is as reliable as the day is long, we flog the crap out of it and it runs and runs and runs.  

We have another car that is a high strung beasty, its a thrill when it works but it breaks constantly.

We've learned much more with the reliable car.

I'd recommend leaving the power level as is. More power = more cooling for everything + more brakes + more fuel + $$$$$$. Nothing is more important than seat time and having a reliable car for that seat time is important. Also, there's a reason driver's don't start off in F1 cars! Learn the limits of the car as it sits first and develop your driving skills before thinking about more power.

Just an update. I bought an s13 silvia with a s15 bb turbo nismo diff. ti exhaust etc. So I will no longer be turboing my NX. It will remain as is except better pads for track days (carbotech xp8 or 10's). Thanks for the input guys, I will be using the nx for the majority of track days though the silvia will be used on the at least one of the last ones
