okay - specifics. the idea is to build a 1000kg car that will run a flat 11 - maybe a little quicker. any faster and i need to fit a full rollcage as per ANDRA specs - which technically makes a vehicle unroadworthy here in Australia. trying to avoid this scenario - will be hard enough getting...

well, i have a gigantic KKK unit. it's so big, it has trouble fitting next to the engine in the battery bay of a good mate's 308 HZ stato engine bay (big engine bay for the amercans out there). it's a twin entry - so to see if it would spool we stuck a pair of leaf blowers up to it, with some...

i see your point about $$$ vs gain there, but it may still be a possibility, and that's all i'm saying! cheers.

is the lower half of the manifold where the flow restriction lies? sorry - i had no idea. might help if i was on a little more.

maybe a custom top plenum might just be the go? design it with bellmouths into the stock port matched runners and at least 4.0L capacity with a stock TB...? i was looking at a pair of 4bbl throttle bodies on the stock lower half of the manifold with a thin CNC adaptor plate with skewed ports...

i don't pretend to be a "god" ...! christ dude - i'm about not discouraging people from trying something new. period. before this gets way overheated - you are correct that my nomenclature is lacking. i'd still like to see a 1JZ/1GG head gasket against a 1GZ as well. all i'm saying is if you...

i just don't see why toyota would manufacture a whole new head for this engine - surely it would have to be close to a 1JZ or 1GG head. mirror casting would be a biatch though, but i guess no different to fitting the GA16DE heads to the 3.5L rover V8...

but we're not talking about a UZ V8 vs a 6 pot head - we're talking a GZ V12 head and 2x 6 pot heads. the 7AFE is a 4 cylinder and the 4AGE is a 4 cylinder from two totally different families of engine (even the bock heights are different) - yet the only thing needed to make the two come...

Or "Top Gun" we should put it under his username instead of just "moderator"...!

good work. i think a plane ticket to get you over here for that type of negotiation would still be cheaper than an R154 here...!!!!

mate - have you actually put a 2JZ head on the 1GZFE? or even compared head gaskets? if you haven't, then you should probably refrain from posting on the subject. if you have, then my apologies. discouraging people to try stuff, just because you "think" it won't work, is not on...

where on earth did you get an R154 for $200?

i have been thinking VERY hard about an S13 - they are such a great platform and i'm surprised we don't see more drag racing. who needs an RB?

looking really nice there - rear sump setup? R&P steering as well - can't wait to see the finished startup.

not cool at all. those cars are about metal and chrome - on the inside.

do you NEED ps? or just want it? because if it's not ps now, and it's not rack and pinion - then you're in for a wonderful exercise in expense. check for recirc ball steering and if it is, then you either need to convert to R&P to get ps, or try and graft in some F100 steering box with fluid...

Hi Paul, Just confirming Thursday morning for a view. If i put it up here, I'm less likely to forget. Cheers, A.

trouble with the subi stuff is the flange is gigantic and odd in shape - may not fit the sapce available. what about a disco spud?

i'm considering going the other way - 1UZFE heads on a 2UZFE block using 2UZFE gaskets. the 2UZ pistons are low comp anyway, aren't they? the relief in the piston crown is quite large...

so, FastEddie - what parts did you actually use? sorry - i'm a bit confused.
