I am new to the forum, and just thought some of you might be interested in what has been my pet project for the last two years. (it was supposed to be finished in 3-6 months! )
I have been building a Datsun B310 Sunny to be used in our local race series here in Australia. It's fitted with plenty of good gear including a tricked up FJ20 Turbo with custom plenum and high mount turbo manifold, all controlled with a Motec M4 pro with Lambda and datalogging of course.
Here's a pic taken earlier this year....we have added some sign writing since.
Anyway's....if any of you are interested in a bit of a read, you can go to the web site....
Yeah....FJ20 with T28 Turbo, highmount exhaust, custom plenum, 550cc bosch injectors, big cams, Forged pistons (9:1 comp!) and the Motec to run it.
I thought I was ready forthe dyno, but there 'seems' to be an issue with the clutch (Tilton Twin PLate - 7.25"), so I need to drop the gearbox back out to inspect it before we run it up on the dyno.
As I am about to go on holidays (to the states)....it will be late January before it hits the dyno.
bro, i'm currently building up my B310 also but using CA18det engine.... i'm having trouble with the rear suspension as the set are separate, it means that i cant use adjustable.... note that i'm using lancer gsr axle... how?? can u pls help me???
In the rear, we used an S12 Sylvia (H190) diff. We cut off the spring platforms, and machined up some new ones to suit the smaller diameter springs I am using. Then, we welded a plate in where the top spring mount would normally be, and then welded a threaded tube section in to give us the option of adjusting the height in the rear end.
I used a Noltec Kit which costs around $365 Australian Dollars. The only thing we changed was, the mounting hats...they came with alloy spring hats which we could not weld to the diff housing, that's why we machined up some steel ones instead.
The links below will take you to the pics of the rear end....
i've been searching for the s12 diff and its damn difficult. they have not got those stuffs unless u are at it full time. but there's this guy i meet who has a shop that does suspensions and absorbers customed made. thinking of getting one and save the hassle but its gonna cost me RM3k. maybe i'll stick to my modified tokico absorbers for a while and get some adjustables later. dont really have time, working like dogs to earn money for my car dude. maybe after i get to learn how to upload some pic n then u can probably teach me a thing or two about my modifications.... but anyway, thanks, maybe ill do that if i get the diff.
Hey guys, just had the car on the Dyno yesterday, and I have placed a copy of the printout below.
We made 183rwhp at a little over 6,000rpm running 15psi boost. Torque was 850lb...so plenty there. I was hoping for 200, but we didn't quite get there.
If you look at the graph you can see the car was making good power all the way to the 6,00rpm point....then it hits a wall.....this wall is the stupid restrictor we have to run in our category. The combination of big camshafts and big turbo simply do not work with the restrictor. After I have taken it to the track a couple of times, We will pull the head and place factory spec camshafts back in the car with the appropriate valve springs. Also, we will source another turbo with the right specs for our application. Afterthis is done, I will also add a water injection system so that we can advance the timing another 5 degrees...this alone should give us 20hp.
We are aiming to make full boost at 2,500 revs with a usable torque curve from 2,000 through to 6,000 rpm. The goal is 240rwhp and over 1,000lb's of torque....we know we can't make much more than that with the restrictor in place.....I'll let you all know how we get on.
Notice the slight dip in the power curve 3/4 of the way up.....that's where the cams really started to work, just under 5,000rpm. Combined with the boost, the car really sat up on the dyno....they ended up strapping it down to make sure it didn't climb off the dyno.
this may sound just a lil crazy to yall, but what are your thoughts of dropping a Dodge 318 with twin turbos mated to a four speed auto and a Dana rear end into my 79 B310?
Congratulations on your fantastic buildup of your B310. I enjoyed your well documented website and great pics too. It took a lot of work and talent to make all of that happen. Keep this thread going. I'd love to hear any updates you might have with the car or racing events with it, etc.
