As I said before Mr house said that on the straights Garwood (porsche) had the legs on him just, But was holding housey up in the corners. the thing just stuck to the track was awsome to watch. Well worth going to the track and watching. Be very interesting to see once hes ran the car a few more times and if comfortable with it.

I thought Ivan told me it was doing 60's flat?? just checked the LCCT site and no results yet. They had a guess at the diff ratio for Symmons and were waaaayyyy off, the thing was falling off the cam big time between gear changes and was only just getting going in 4th at the back of the sweeper! plenty more in it yet!! As for boost I'd better extract a digit, his car was a huge improvement over the June clubday, and it sounds like it will only get quicker, hopefully we will see him at the NWCC Clubday in Oct, where am I going to hide the bottle of NO2?. Also if we keep at him, we might see Wombat on the track! and have you heard Wombat, Decky has finally been beaten for the khana cup, Coop took the championship on Sunday.

Mick did a 64.3 at the Baskerville club day. If I don't watch out he'll soon be beating me in an N/A version of the same car! Thanks for the heads up on the P90 Wombat. I don't reckon I'll bid on it unless it stays real cheap. Will be interesting to see what it goes for to know whether or not I paid too much for mine.

Scando, you just need to slip that head on!! Kelvin gave me the run down last weekend on the said unit, they sound like a trick bit of gear! Whens the next Octo meeting??
Sadly my Eastern Creek trip fell in a hole. The event runs all weekend but the public is only allowed to go on the Sunday, for some bizare reason?? We had a couple of different people lined up to get us pit crew passes, like we had last year, but they fell through, and it's a big trip for only 1 day!!, oh well next year.
As for the FJ it would be wasted on a mug like me!! Dont worry about Mike, Scando, if he get's to close you can Screw a bit more boost into the big block, he can't, he he he .

As for the FJ it would be wasted on a mug like me!! The results from the Minna Rd hillclimb suggest otherwise The next Octo meeting is the 14th of Oct at Symmons. Apparently my pistons are in Aust now and we should have them soon. The P90 heads are supposed to be pretty good. It'll be interesting to see how this engine goes. My only concern at the moment is that I think it'll lower the comp ratio too much. The guy I bought the car off thought that shaving the pistons had decompressed the current engine to about 8:1 (L28's are 8.3:1 standard) I think the new engine is going to turn out at about 7.5:1 with the P90. I don't want an engine that's a pig off boost and then a tyre fryer on boost. I guess I'll just get the thing together and see what it's like. It's not too hard to get a bit taken off the head if I decide it needs it.

Hmm, sounds like you need to get the pipete out and cc the head? dont ask me how to do it!! he he, Boost or Datsreal might have a few tips?
14th of Oct there is a clubday on Baskerville!! Did George W bring your pistons over in his hand luggage?? now, that would be service, and I have heard the the Prez is a bit of a closet Zed fan! On the 15th of this Month the NWCC is holding a Novice/come and try Rally behind Ulverstone if anybody is interested in running or spectating?? I'm sure we will see Datsltd in action in the mighty Bluebird, and several other Datsuns as well, if your interested give DatsLTD or myself a PM.

Yep, that's what all the security and the 12 car convoy was for. They weren't too concerned about George, just worried about my pistons making it here safely That's poor management having a club day and SuperSeries round on the same day. The guy that checked the head out for us measured it and got 54cc. Dad measured the block with the standard pistons (the new pistons should be exactly the same as standard ones just forged instead of cast) in it and a head gasket sitting on it and got 27cc. Bore will be 87mm and stroke is 79mm. This gives a comp ratio of 6.8:1!!!! The info I've found said that a P90 is 53.8cc (about spot on what the engine builder got) but it also said that standard pistons should be 10cc and if I run a 1mm head gasket that will be another 7cc. This would give 7.6:1 which is more reasonable. I guess we'll just have to measure the block again once it's all back together to see what it comes up with.

The pistons arrived yesterday But somehow they stuffed up and made flat-tops This may yet be a good thing. Gotta pull the old engine apart and see what compression I have been running. The flat tops with the P90 and a thick head gasket might be perfect.

Scando, that explins why big George skipped Sydney so quick!!
So will the forged slug's allow you to run more boost, and higher rev's?? or is it just for relability?? Cosworth used to be all the rage, but with yours coming from th US, are they another brand? hopefully it will all work out for you.
DatsLTD and Buck are you ready to run the rally?? fixed the diff?? Rog and I are sitting this one out, but I'll be doing a control. Did Buck find a probe for the terratrip?? how will he go using such a complicated peice of equipment? as we all now how technologly callanged he is!!!!
Hey wombat, have you put a bid on yet?? will you be taking home the class A black tack trophy next year?? running the clubday??

Pulled the engine out on weekend and measured it. Seems we've been running 8.2:1 compression so the flat tops will do just fine. Also decided there's not enough time left to get the engine built so the internals I've been running will be going into block no. 3 for the year! I'll try to get hold of another block to build an engine with the forged pistons so it's ready to drop in at the end of the year. So the plan is. -Forged pistons to cope with more boost and add reliability -P90 head for better flow and reduce detonation on higher boost. -Run one of Kerry's old computers so that timing advance can be run off boost and reduce the advance on boost (my current computer is fuel only) I'm not worrying about getting everything balanced or changing the cam to run high revs. Just want to make as much torque as possible Hey Wombat, seen this yet? www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Performance/Core-engine/auction-117130714.htm?p=1Ok, so maybe a little expensive but imagine it sitting in a Cherry

Jesus....190hp from a push rod 1500, this guy is a genius!!! I might fit it into the Rat!! Did you see the FJ24 on the same site, with a cracked block, gee there as common as L20's in NZ, mind you I didn't see any last time I was over there, and I looked pretty hard!! Sounds like it will all fall into place Scando, Is your engine held in with Velcro?? It would make life a lot easier! Bugger Kerrys computer, I'd be chasing one of his 6 litre's, he must have a spare one laying about. I'd be talking to that engine builder of yours!! mine told me if he was under the pump, he could build one in a night!! you've got weeks he,he,he. Maybe you could build a development motor and run it in the Skyline at low boost? you could sleep in for an extra ten minutes every morning, bonus!!
DatsLTD I hope the drive bye's dont include shooting!! The 4.6 will make a big difference.

Good Luck ;D Yeah I guess 190hp from a pushrood 1500 would be a bit of a stretch but you never know. How much was the FJ24 with a cracked block? Not to hard to get hold of another block. Nah, don't need velcro when it's as simple as a datsun! We're getting fairly well practiced at it now so it it's getting quicker and quicker each time Wasn't too concerned about the time it would take to assemble the engine, we can definately do that in a night. It was just getting the engine builder to machine everything and then getting it run in once it was together that concerned me. The 6 litre would give me a little more power than the computer (just another 400hp or so more than what I'm running at the moment) But I don't think he'd be so keen to hand over one of those. Maybe I should put a turbo L6 in the bluey for 'development' ;D At least it'd save all the trouble I'm having with these bloody CA20's

The FJ is $5000nz, It looks like they are a special block, but he has a spare one..... AVALIBLE, I'm guessing that he's not going to throw it in!!
Yeah, It's the usual story, bang for buck a turbo makes a lot more sense, but for pure bragging rights nothing would beat the FJ24......

Post by scando on Sept 11, 2007 13:23:27 GMT 10
oh, ok. So they don't use the same block then. I thought it might be as simple as putting FJ24 crank, rods, pistons into an Fj20 block.

Scando: I would love to have that engine or even one half as good. I dont think I would be able to keep gearboxs up to it though.
Bluerat:I didnt bid on it in the end as the guy wouldnt talk to me I sent a couple of questions to him about the car asking for a few more photos and what brakes and suspension the car was running I even gave him my number to ring so that I could talk to him. I will be dissipointed if it did seel for the price that the auction finished at ($305 reserve not met). I was thinking it would at least go for $600-800.

Wombat, Thats a shame, hopefully he will contact you with some details and a price, gee's for under a grand you cant go wrong!!! tell me is it front wheel drive Pulsar? It's a bit hard to tell under that 'wild' paint job!!
Scando as for the FJ24 block, I am in no way an expert!!, but that is the way it read?....hold it a minute, I'll just drag out my 84/85 Rallycourse annual......here we go, 92 by 88mm bore and stroke....how does that compare to a 2 litre FJ20?? Deane'o might know??, if a 2140 L series is 89mm bore then they are a fair bit bigger!! some other intresting facts on the 240RS are 2340cc, 11.5:1 comp, 261bhp @ 8000rpm, twin 50mm Solex's and 980kg Nice...but she's no Lancia 037!!! Christ I sound like a nerd!! I'll be quoting part numbers next.......Oh yeah Scando a while ago you promised to tell us what the new thing Kerry was building???

hehehe, I haven't had an update in a while but I think it's still a long way from being finished. I'll try to get a photo off him when it's done 261bhp is damn impressive for a NA 2.4. Most 2ltr turbo engines don't produce that standard! Any idea what sort of torque they had? I'd imagine it would be heaps with a 88mm stroke. Imagine what one would be like with a turbo on it................Must be tempting Deane Check out the post at the bottom of this thread. What exactly is the rat up to? ozdat.com/forum/viewtopic.php?t=8663&start=15Gotta keep an eye om him

Not a bad question aye!! It seems like as soon as you put a pair of webers and a cam into any 4cylinder it has 200hp, you wouldn't beleive how many Kent/Pinto Fords, Mitubishi's, Gemini's and of course Datsuns have 200 plus HP in this State!! and looking at that thread, It takes a hell of a good engine to get that n/a, mind you there doesn't look to be any 'serious' L series engines on there, so what does a 'good' one have?? and when I mean good, I mean 13 second quarter mile!! not bloody 17's....and no I dont have 200hp and mine won't do a 13 sec quarter....I'l get off the soap box now...I've had a few sleepless nights lately worring about how square my shell is due to the fact we are finding it very hard to get it wheel align'd, But I towed it yp to a mate's place last night, who is a panel beater and we got out the tape, and much to my releif it is a square as....so it's back to the drawing board, can't be that hard. Oh yeah I popped into Macca's for tea last night and when I came out there was this guy parked next the the Rat on the trailer, he said " Mate I've been waiting here to tell you that you left your key in the boot of the Datto", aahh thanks mate!!
