i have a certain friend with a 87 rx7....
he is thinking of swapping out for a 6 liter lq9....
he plans on running 5.3 heads to bump up the compression. what cam would work the best. he's thinking ms4. how is the driveability of that cam, and how much does it cost, and where can we get one...
what power levels should we be expecting?
he is also interested in doing a stroker set up, what all needs to be bought to achieve the stroker? whats the best deal for a stroker set up for this motor. keep in mind this is a budget build

You would probably get your info in the internal / external engine forums. Not the General LSX one. Also, all this info can be found if you spend some time and use the search function. Sorry if it sounds like I'm being an ***, not trying to be, just tryin to help

Plus a more specific topic title would do more good than "Help"

Yeah try that forum.

As far as the ms4 cam...I have stock heads..with bolt ons...made 420rwhp and 370rwtq.

As far as drivability...egh..I have a 6-speed..it is barable..pretty fun..cuts up good. Would not put in a automatic. You would need a huge stall.

And try texasspeed.com

u will also want springs and new rods.

tune will be spot on with nic d tuning the car, he's one of the best in the nation.....
is it true that with an ms4 you have to change springs and such every few miles? i close friend told me that but i don't know if its true or not

how much will a set of 5.3 heads bump up the compression on a 6liter

Kev SS

no you do not have to chang springs everyfew miles. Another roomer is you have to flycut the pistons...this is also not true.
