I've got an 85 Toyota Corolla in the process of receiving the F20C motor/tranny transplant. The car will see quite a bit of time on the track (once a month road course, and at least once autox). I will be running race gas at the track FYI. I need to build this motor to be reliable at 7psi driving it fairly hard at the track for extended periods of time. I am not looking for anything more than the power that the Lovefab kit offers out of the box, so roughly 330whp (my rear end starts breaking stuff around 400whp).

The motor was pulled from a wrecked S2K with 42k on the clock. I am doing a full rebuild on the motor, but I am wondering what I need to go with. These are my thoughts so far, please feel free to give me some input on this, as I'm fairly new to the F20C.

Items I have already ordered:

Cometic Head Gasket (89mm bore, .030 thickness)
Full gasket set for the entire motor
ACT 2100 clutch kit w/ street disc
Koyo Aluminum Radiator
AEM EMS



Should I do any/all of the following?

-ARP Head Studs
-Remote Oil Cooler
-Larger fuel injectors (what size?)
-Fuel pressure regulator
-Water/Methanol Injection
-Reccomended Spark Plugs
-Rings/Seals
-Fuel Pump

Is there anything else that you guys would reccomend? I hate being such a noob
but I'm trying to do this right the first time around.

I appreciate the advice!
Thanks,
Jason

 

Your setup looks pretty good, IMO. The head gasket might be unnecessary with the race gas, but a little lower compression for the track can't hurt. I'm not sure how many people are running the Cometic gaskets, but some people have had some sealing issues on other motors (VQ35DE, for one).

As far as the other parts, I'd go with the ARP head studs, the remote oil cooler, and 2 step colder plugs. The FPR and water injection are unnecessary.

The only other thing I'd say is that you might want to go with the stock clutch and a ACT pressure plate instead. The OEM clutch is pretty decent and has nice engagement, and the pressure plate will help contain the extra power.

 

Thank you for the response.

So do you think getting in to an internal rebuild (just rings and seals) would be overkill on a motor with 42k?

 

On one hand, 42k miles isn't bad for a Honda motor. On the other hand, there's no better time to service an engine block than when it's already outside the engine bay.

I haven't built a block for boost, though, so I'll let others with a bit more experience chime in.
