Building a '02 Celica GTS for RR... Few Q?

[Lazarusresurrexit]

Hello all,

My friend and I are building his GTS into a track car. I remember one or two members here used to autoX and road race a Celica. Just wanted to see if anyone had some tips or must-do modifications on the high reving n/a cars.

We just installed Hotchkis sways, lowering springs (1.5"), stainless break lines, gutted the car completely and will have a cage soon. He removed the muffler and one res. Car sounds mean when it hits the lift, however he is experiencing popping and spuddering at high rpm's. We haven't touched the engine yet so I'm not sure what is the matter. What would be a good means to doing basic tuning? Do they make chips for these cars.

I want my friend to get some track time before he touches the engine. I was very surprised how fast his car is through the twisties.

We will be heading up to Savannah sometime soon and after that, Sebring. I need to do some research on the engine and find out what mods are best for the high revs.

Thanks in advance for all your help.

I hope it goes well. The only thing I know about the GTS is two guys who auto-x in my region no longer use that car due to oil starvation under high g loads. Motors went pop. May not be a problem road racing. Not nearly as much constant lateral loads.

That's very good to know. Thank you. I will look into adding a windage tray and baffles. Maybe work on a bigger pickup tube and oil pump.

I remember one of the members here in srtforums had a GTS and autocrossed. Not sure who it was.
