Found one thanks. Im chasing a boot lid with no spoiler holes. Need asap this week so will need to be brisbane cheers

I put mine in collapsed. Get a couple of solid lifter to use. You can gut and shim an old set. If its std deck height id just run them as is, all the gsc ones ive done on std deck stuff with factory thickness head gaskets have come out fine. Unless you want to see p2v and v2v on big adjustments.

Yeah mine does about 3900rpm at an indicated 120kph, which i checked on gps last week to be around 124kph. So yours sounds similar to mine which is on 215/40/17s

Bump. Thought i had some sorted but the seller backed out because his replacements never showed. Would pefer east coast.

Im putting a/c in my 63 converted gsr and need to know how many and the locations of the pressure switchs on an e2. Iv got some hoses that have been custom made for someone but i want to run my lines different. At the moment there is 2 in hoses and one in the vr4 reciever dryer im using.

1-9 exhaust head flange is the same. 1-3 inlet the same and 4-9 inlet the same will not fit vice versa.

Im no help on early ones but on late 4-9 4g64s you use the 63 tube and dipstick. The location is same on both blocks and the dipstick suits the sump.

Have you got the a/c hose and pipes that go from the firewall to the condensor?

Yeah this is what buscher found a year or so back when brewing his on ethanol.

So whats the comp, 10.5:1? Id still ram boost into it. You could go bigger cams and try loose some dynamic compression or if these have the paper thin 93 head gaskets then change to a thicker oem turbo gasket. Or even water meth or flex fuel for high boost. I wouldn't waste time porting the head...

Am i missing something here?? You run 13psi high boost and are talking about getting more flow through the head. See how it likes another 5psi first, maybe ramp it in after 4800rpm being a 93.

Too late now but i would of gone 60mm throttlebody with 2 1/4 hot side and 2 1/2 cold. Just wind the boost up.

Location?

20g is a compressor wheel. It can be on a tdo5 frame or Tdo6.

My stock block gsr had evo bolt ons, std gsr ecu and airflow meter with an safc 2 that i tuned on the road. Went 12.5@111. My hx35 built 93 went a bit over 315kw (trapped 127mph) and had an 8k limiter with kelford 272s and made no more power above 7250rpm. Its all in the tune i bet i could get...

20g will probably be easier on the rods than a 16g on 20psi.

Depends on manifold back pressure and gate size as to if it would work on a screamer pipe at all. I have thought about trying to run a vac pump but to do it properly you need to run a mechanical pump imo. Next drysump car we tune ill log that too.

Bingo.

lol my dyno pressure sensor does not lie, vacume=below atmospheric pressure. It only just dips in but its still seeing vacume. And your statement is wrong, think about how an exhaust scavenging breather system works and then think about what an intake is doing. Yes similar to oem but im not...

Im not worried about either.
