Quest 4 MPI


Recommended Posts

If its got braces most likely you are going to have issues...just speaking from experience. None of our manifolds have braces and have not cracked. Hate to see you having to get it re welded over and over and over.

From the picture it looks to be thin walled exhaust tubing. That if thats the case its not going to hold up. Also the welds dont look good at all. Do you know if it was even back purged? What info do you have on it?

 

 

Again not talking crap just trying to save you some headaches down the road

Should have went with 3" exhaust if your running that holset.. it needs to breathe

 

Im going to be running a 3" DP and 3" pipe back to the HKS exhaust. I will have a E-cutout in that mid pipe so that when i want to go all out it will be straight 3" to the ground, but for highway and city driving it will be nice to not have to listen to the loud droning noise coming from a 3" exhaust. dont get me wrong i love the sound of 3" but when you have to listen to it on a 10 hour drive to a car show it gets pretty damm annoying lol.

Ok so someone answer me this; With my intake is it necessary to run a thermostat? And if so were and how do i run one?

 

Also does anyone know where i can find a toothed crank pulley for wasted spark now? becasue Mookeh stopped selling his and i dont think fuel injection pro sells theres anymore (plus not planning on sending $900 for their kit).

OK so D2's are in the mail and all my suspension is almost completely prepped for D2 installation.

 

Also RonnieJ is building me a twin scroll Manifold and 3" down pipe to 3" mid pipe that will tapper down to 2.5" to fit perfect with my HKS exhaust. Really pumped to get all this stuff in progress. Also getting my hot side ceramic coated. and a big lot of parts getting powder coated black (controller arms, timing cover, oil pan, spare valve covers, and lots more).

as far as tstat housing install you need a remote TSTAT housing.

^^^what he said. go to advance auto and get 2 of there fancy chrome dress up thermostat housings for the sbc... put them together and you have yourself a remote thermostat. its like 15bucks... done... now what i have done is drill and tap a hole into the motor side of that exhaust housing and put a hose to the back of the water pump steel tube that runs around the back of the motor. so that you have constant flow across the spring on that t stat. remote t stats are prone to be slow and cause overheating issues due to lack of a constant flow. i also "T"d that little hose to the back coolant line in the head that runs to you heater core,,,,, cause the only way your flowing coolant to the back cyl is if the heat is on.... do some digging around.. you will see most people that have ran into trouble with the back cyl once they go mpi with these style intakes. they were actually using copper head gaskets to try and stop blowing the back cyl.

Wrngwea,

Having some difficultly figurin out exactly what you are talking about there. So what needs to be drilled and tapped and what needs to be T'd ? Pics would be awesome.

 

Funky Phil,

I figured the 2.5" will most likely max out but i have it on there for a DD exhaust noise. i will be adding a E-cut out to the system after all is said and done so that when I need the extra power there is no restriction at all. as far as my goals. 400-450whp thats what im shooting for. IM gonna be running MS2, ignition: 4g63 wasted spark w/ 36-1 VR trigger wheel, Fuel: E-85, 1800cc injectors, Walbro 400lph, Exhaust/Turbo: JDL Twinscroll header, JDL 3" DP to a 3"-2.5" Mid pipe that will attach to my HKS catback, HX35 w/14mm TS exhaust housing, Block: Wiesco std pistons, Stock race preped rods, full engine rebuilt stuff from Dad, Ajusa head gasket, APR head studs and rod bolts, Head: Ported and tested on a flow bench, 3.3L beehive springs, 1mm os ss valves, LS1 retainers, (For the Cam im not sure on what i want to run yet i would like to have a steady idle but would like to still get the performance gains of a bigger sized cam.)
