I brought an 04 with an blown motor, I'm looking for a quick fix and sale. I have an j30a1 available at little to no cost could I drop this motor in? With no issues???
I'm confused, he's asking about a J30 swap, post in a 4cyl section, and your telling him to get a TSX or Element engine.No get a tsx or element motor instead
sorry it should have been in red. lol Cuz it posted in the 4 banger section.I'm confused, he's asking about a J30 swap, post in a 4cyl section, and your telling him to get a TSX or Element engine.
J30a1 will not work due to it being drive by cable and other no compatible elements, and the J30a4 is drive by wire
your a dumb ass. read my thread.There are no differences between the two that make an a1 block no useable in a 7gen. Do you know anything about j sieries difference or are you talking out your ass? The dbw is not an issue if he keeps his pedals, intake and sensors that came in his 7th gen. Coil on plug difference? Doesnt matter hed be keeping his stock harness ecu and using a4 coils..exhaust differences, the a4 had integrated manifolds to the head if not run cheap ebay exhaust for the a1 then he couldda swapped his a4 heads onto the a1 purley to retain his stock exhaust system, which would come with new head gaskets and chance to look into the motor..im not spreading bad info, dont be one of those guys; "its not possible buy new car"the a1 motor can def be used in a 7gen dont belive me grab a wrench son
I was thinking this was the deal breaker on using the J30A1 block...... it also doesn't have a knock sensor,
They will, its been confirmed by NVA-AV6. Minor detail is a oil passage in the J30A4 head will need to be plugged up....The a4 heads should bolt onto the a1 block
Interesting. Would like to see how that would work out.Knock sensor will throw cel, but its not 100% necessary my wife's currently driving a j35 vue with malfunctioning Knock sensor and no appearent power loss suv runs great. If its that big of a deal tap threads into the block and wire knock sensor to the correct ecu pin.
The mounts are easy to figure out as the a1 lower trans mounts should bolt to our 7gen subframe and on the a1 block you could use your a4 timing covers and engine mount bracket, and the a4 engine mount.
Good point about the oil passage, this is the type of info the OP was originally looking for. Now were making a good thread lol. Anywho, ive added and seen people add knock sensors in older d sieries swaps its 100% doable, and yes i have compared the engine mount bracket bolt holes and all three bolts line up between the two blocks, meaning you could use either block a1 or a4 in either chasis granted you use the engine mount and engine mount bracket from the chassis your using. So a1 motor in 7th gen would require the a4 engine mount bracket and engine mount. As for the tranny he could keep his stock tranny and not have to mess with his tranny mounts
