Looking at doing a conversion on my B18 vtec... Do i need to change the pistons rods and uprate the head gasket? It has just had a head gasket change but would i need a upgraded one?

I will only be running low boost as it is just for a small project on my EG

 

you will be fine with a good tune

 

so i wont need to put a decompression plate in or anything to lower the compression?

 

you can make 350whp with a good tune

 

and i also believe i will need to change my map sensor and injectors, will rc 440's be ok with a hondata s300 ecu?

 

if you plan to run under 10 psi, stock map is fine

also you can use dsm injectors/ they are 440cc and can be had for cheap

i also like eCtune management. ectune.com
but use what your tuner recommends.

 

dsm injectors? im lost lol

 

^ evo injectors ect

 

oh cool cool... but i do have to get a new ecu dont i? like a hondata or something similar?

 

Many of the managments you can use will just add on to the stock ECU. Call the shp and ask them what they would tune your car with. Then come tell us what they prefer to use and we'll tell you if it sucks or not

 

I have spoken to a guy at my local tuning shop and he recommended a hondata ecu... is it true that i can download a map for the s300 via usb just to get the car running? and then take it to the shop to get it mapped up correctly

 

good, if that's what he sells and tunes, and he has a good reputation, go with that. As far as the basemap thing, I don't know, never played with that system. Your tuner should be able to set you up with something to start it with anyhow.

 

once i have everything all fitted and ready would the car run before i change the ecu or would it not run at all untill i change the ecu?
