4age silver top questions

YELLOW_MR2 · 05-08-2009, 12:02 AM

Well im looking for the best way to build my 86 MR2, the problem it has right now its that I need new pistons and rods and getting the new pistons and rods that i want is almost the same as getting a silver top..So any suggestions on what to do? Also doe the tranny that my MR2 have bolt up to the Silver top 4age and the harness do i have to change it??also would my 4age blue top head fit on a silver top block??

It needs to be custom wired (unless you get a PnP harness from mr220v) and the 16v head fits (20v intake won't bolt up though needs an adapter) but it's a backwards step you are better off with the 20v head with the vvti and such. Tranny bolts right up I did it yesterday when I bolted the locker on my new engine

I used the silvertop clutch it all fits perfect.

I am still trying to figure out what harness I need on my 20v mr2 and what ecu. I think that I am going to go with an auto ecu and jumper the park sensor so it starts. I can wire it, will just do it like my mk1.5 but there are a couple different ecu's and I don't want to burn one out plugging it in.

Oh ok i said that because what i was looking for was a block with pistons and rods..instead of repairing my block..I see what you mean though I think im going to get the silver top, the whole motor..

I purchased a BT from JHOT, came with a bunch of parts like ECU, cut wiring harness, transaxle, even the intake and air filter box. I feel I got a good deal. I've put 16K miles on the engine, no oil burn and I flog it.

Research carefully your importer - reseller, there are several out there that are shady.

I used a MR220V wiring harness, no complaints with him or his service either.

Good luck.

Thanks, I'll check them out and see whats there, if not since money is low im going to get the stock pistons mean while and do the swap later, and is the BT weaker than the ST??

The blacktop rods are weaker, they are the only rods in the 4age line up I don't trust. They don't usually give a problem on a stock engine but I have heard of bent rods on thrashed modified motors.

man no one has posted on this for a while...

but uhm yeah i bolted my trans from my 16v bluetop right up to the 20v ST, i had a new clutch kit and balanaced out flywheel already so i threw it in there.

Club4AG Forum Topics: SilverTop Vacuum lines
the two lines that are question marks and pointed out in every picture...get plugged...so does the little line on the front of the collector box and in the intake elbow

did you get a 20v transmission with your engine? they are better gear boxes

If your pressed for money why not a smallport swap? The engine can be had for 400 complete and can put down the same power or more than a smallport with ease. And it will run just fine on your stock electronics.

Nothing wrong with BT rods if your staying NA, honda engine run thinner rods at higher power levels and higher rpms no problem...
