Guest Jim226 Posted February 5, 2005 Share Posted February 5, 2005 Hi everyone i'm kinda new to the forms but not to the z world....my dad is the one who got me into them owning about 15 throughout his life, now the "z bug" has bit me. I know that all U.S. Z'S came with the OHC L-6 but i was wondering if any1 knows if there are any places online that you can get a S20 DOHC L-6 or the cross flow motor i know these are the holy grails of engines but any japanese websited that might have these motors would be great.

cheftrd Posted February 5, 2005 Share Posted February 5, 2005 Jim, Don't mean to be a dream destroyer, but.....for the price you could buy an S20 for, if you could find one, you could probably do a complete RB26 swap. No joke. Even then, there's no way you could find all the extra stuff needed for that engine. If you're dead set on this, your best bet is to keep your eye on the Japan Yahoo Auction．Good luck Quote Link to comment Share on other sites More sharing options...
Tony D Posted February 5, 2005 Share Posted February 5, 2005 Not a Dream Destroyer, you COULD do a complete RB26 swap for the cost of a BLOWN UP S20! People that got 'em, don't part with 'em. And they usually have a spare, just in case. Quote Link to comment Share on other sites More sharing options...
HS30-H Posted February 5, 2005 Share Posted February 5, 2005 I can confirm from personal experience what Matt and Tony have told you. S20 ownership - even in Japan - is not for the faint hearted. I have two engines; one at home in the UK and one still in Japan. I'm using the best parts from both to make one good one, but the rebuild parts alone have been costing me a small fortune. Photos here: http://www.classiczcars.com/photopost/showgallery.php?cat=3069 There's a lot of baggage that comes with an S20 swap, such as the need for a different front crossmember and the correct trans to bolt up to it. There does not seem to be much point in embarking on this conversion unless you carry it out with an eye to a certain amount of period detail and period flavour. The S20 is not a big power engine, and I keep telling people that my project car ( a fairly period-correct 432R replica ) is all about just that - flavour. The 'LY' sohc crossflow head is a step up to another level entirely. These things make S20 engines look positively common. They command huge prices in Japan and anybody who is thinking of selling one will usually have a waiting list of people that booked a place in the queue years in advance. The full 'LY' conversion included a special crank, rods and pistons, flywheel, damper and numerous other details. Don't forget that it too - like the S20 - needed a different bellhousing for the trans in comparison to the normal L-series 6. I don't want to be a Dream Destroyer either, but these exotic pieces of Z history don't give you much in the way of 'bang for buck'.......

Cody 82 ZXT Posted February 5, 2005 Share Posted February 5, 2005 HS30-H, How many headbolts does the S20 have. Did I count over 30 correctly or where several of those water passasges? Quote Link to comment Share on other sites More sharing options...
HS30-H Posted February 5, 2005 Share Posted February 5, 2005 Hi Cody, The S20 has 26 head bolts in total. There are 14 bolts that pass through the head casting and thread into the block. These are all located close to the cylinders, as you would expect. Additionally, there are 12 smaller studs threaded into the head casting. When the head is placed on the cylinder block, these studs pass through the cylinder block along the outside edges to emerge on machined flats under a ledge. These are then nutted and torqued in sequence with the rest of the head bolts. The mains caps are cross-bolted from the outside of the block too. Its quite a complex and over-engineered piece. They must have cost a lot to make. Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted February 6, 2005 Share Posted February 6, 2005 Hi Cody' date=' Its quite a complex and over-engineered piece.[/quote'] Sounds like it. I can only imagine how stout it must be. As good as the L-28 but, better! Quote Link to comment Share on other sites More sharing options...
turbobluestreak Posted February 6, 2005 Share Posted February 6, 2005 I just saw your gallery on classic zcar club and I had no idea that the white z was your z, I've seen pictures of that before and it's breath taking. tbs Quote Link to comment Share on other sites More sharing options...
HS30-H Posted February 6, 2005 Share Posted February 6, 2005 ........and I had no idea that the white z was your z...... I think you must mean the photos of the SPIRIT GARAGE race car? It might be in my Gallery, but its not mine. Quote Link to comment Share on other sites More sharing options...
turbobluestreak Posted February 6, 2005 Share Posted February 6, 2005 Sorry I thought that was yours HS30-H. Could anyone tell me more on how the S20 is timed? Does anyone make performance cams for the S20? I think I'm going to need a set for my custom 24valve head because the S20 valve train resembles what I've got coming together from the two KA24DE heads.
