tbh, i was amazed at what an intercooler, filter, exhaust and boost upgrade did, back then the fastest cars i had where 1800 8 valve mk2 astra gte's and a 2.8 celica supra, so when i got the s12 and a few mods i thought it was the dogs, but it left me hungry for more power, so then i had the engine internals done and a t25, then t3, then t34, so if i'd have gone for a big tubby to start with i would have saved myself a lot of money, a standard engine will more than cope with a t28, or t3, ken finn has run a t3 for well over a year now and its his tubby thats packed in and the engine is still strong, he's now putting a t34 on, so what iam trying to say is it will feel quick for a while then you will want more, thats why i'am doing the fj20 turbo conversion,i think then it will get scary
