[JMOE79]

hello im new to the 240 world and just recently put a t28 topmount on my 97 s14.A friend of mine had all the parts and was helping me but due to our work sch . we just cant seem to reach each other but anyway i need injectors(not sure of what size 370 i think)and info on what heat range plugs and how to gap them . I have autolite ap3923(gapped at 28) but dont think they are what i need . Any info would be great and very helpful

Bkr7e NGK Iridium spark plugs gapped around .033 should be good. 370cc is fine for t25, but need to know what your setup is and your goal.

Plus look through the stickies and then if you have any questions you can make a thread.

well like i said i think its a t28 but really just wont to be able to get in tha car a go without the troubles of a race car hell i have one of those and i really like the 240s . really just want a fun car that is reliable and dont have to be worried about being strained on side of the road lol like i said i have a race car

Wait did you say top mount? best for the t25 and t28 are bottom mount. i didnt know they had topmount for t28.

yea neither did i. if there was i would have bought that instead of the bottom mount. but with my set up i used NGK BRK6ES. its pretty ballin and only 8.98 after tax from napa here in nj.

check out the other thread that i posted in, i gave a lot of info on that thread it should be recent, i think titled as "common reliable ka-t set-up".

Honestly for low boost it should be one step colder such as 6, but i heard good things about the bkr7e.

BKR7E are colder then stock. I currently use them as well.

I believe you can cross reference them with a 2002-04 Jeep Cherokee Overland with 4.8L Hemi.

6 is a hotter plug than a 7..

bkr7e's is what most of us run. At 8 psi you might be able to run a larger gap than 33 just do your own testing.
