is anyone else going for the NA scene... besides me?

 

:?: :?:

 

NA = Naturaly Aspirated (ie: no forced induction such as turbos/superchargers).

 

That might take some time. Also with the engine not having the VVTL-i, I dont think a NA set up would be worth the cost of money. You would be looking at head gaskets, pistons, rods, crank, valve job, intake, exhaust, cams, computer, & some other things. I just dont see the cost of doing a NA build up on a tC, to be worth it.

 

well, considering the fact that the compression ratio is 9.6:1...

that is really low so if you were to increase the pressure to say 11.1:1, there would be a but HP gain. probably an NA setup isnt going to be as quick as a turbo setup but if you know wat your doin... then it woudnt be so expensive compared to a turbo. im lookin to reach 14's or 13's faster woud be nice but i think for your daily and mtn/track racer... thats enough power

 

So would a swap from a celica GTS work with the tC?

 

When you up your compression you loose torque.

 

:? With money any thing could happen. I would not do this swap though. That engine would kill itself in the 2,900Lb tC. It does not have much low end torque.

 

How is that? TQ is what counts, if you lose TQ, then you lose HP seeing HP is just figured out by taking your TQ numbers & doing some math with them.

 

What exactly is Naturally Aspirated, as opposed to what the tC comes with stock? I always thought it was just the lack of a turbo or super charger (anything "forced induction"). So what would you have to change to make a stock tC naturally aspirated?

 

Yes. A tC is a N/A car. It comes stock as a N/A car. What he is saying by a N/A tuning is making the engine produce gobs more power with out the aid of Forced Induction.

 

man chucksu hahaha check out all your posts hahaha


increased compression is not losing TQ. for example: PSI = boost = raising compression in a cylinder = increase HP n TQ. so raising compression with out FI woud result in the same manner.

also considering the relatively low compression ratio of 9.6:1, this car has a lot of potential to add lots of boost or raise its compression. only question is if the engine can handle it.

chucksu i was thinkin about your post on the VVTL-i cams. it might be possible to do a swap? or a 2AZ comversion to have serveral components frum the 2ZZ. SCC had an article on this but it was on a honda. they took a acura TSX n swaped heads with a RSX type 2. so they used a K24 block with a K20A2 head and cams. done deal. and cof course a stand alone ECU to accomdate. and the new engined pumped out 180whp instead of 140whp. crazy stuff


and again... with money everything is possible. i jus really hope i can do such a swap.

 

Yeah im not sure if a head swap, or parts from the head could be done. I think they are 2 different engine series. I think the best bet is wait & see for a while. Even with out a VVTL-i set up, you should be able to get some good power from the engine. Seeing Im going into the air force soon, I already got a good deal of my car mags packed :oops:. One of them had this face off of a few different Civic HB's running the K20 engine. Skunk Racing took the engine & got a little over 200hp to the ground doing a N/A build up. Now that does use V-TEC, but its only a 2L engine. So I think the added .4L of the tC engine could make up for the lack of a Lift feature.

Take the CR up to around 11:1 & run 92 octane. All the other things & wait & see if some company makes some rods, pistons, cams etc.. Also a bigger TB & things like that might help. Might even be able to build a slight ram air style system, might be good for a little extra power when at speed because of the cooler air.
