Hi ive got a celica gt4 st180 and ive done nothing to the engine but i really want to start upgrading it and tuning it.. i have no idea where to start! anyone have any ideas?
Hi,
I take it that will be an ST185?
Do you know if its an import or UK, CS, RC?
As said previously, assuming the engine is well maintained:
1st Mongoose cat back Exhaust (2.5" to stop boost creep later)
2nd Apexi High flow air filter
3rd HKS Fuel Cut Defender
4th Quality Cooler by 1 Grade Spark Plugs
5th Chris GTS MBC Boost controller Upgrade 1.1bar (or EBC if you're feeling flush))
6th Quality 3" Decat (or sport cat)
Should be looking at about 240-260hp by now
Then you should be looking at
Fuel Pump (bad to fit)
Water/Methanol Injection or FMIC
Boost upto 1.2bar
Should see 280hp by now.
Then you need Apexi Power FC (& Commander), remap to see +300hp
Internals can stand 300hp easily if done right, you got to remember this is an ST185, not an ST205 which will yeild approx another 20-30hp on all the above figures.
Just from past experience...
