we are also thinking of puttin a cam or cam's and betta pistons to but we read that the T70 spool up fast.

This T70 turbo was a kit for a CA18 and came with T70 turbo, exturnal wastegate, Stanless Manifold, all the gastet's and golts and a b.o.v.

Alex.

Yep and plus this kit is cheap. Check it out on eBay. I had a look at buying this kit and I learnt a few things. First off all its not a Garrett T70. Look at its specs and try to match it the proper garrett T70. Nothing matches nor does it to any other genuine turbo. Secondly, the manifold, BOV and wastegate are all imitations of the HKS material. Dont expect to get anything like you saw in the eBay pic as it simply wont be the case. I always go by the moto "if its to good to be true... then it's probably too good to be true". I know of someone who has bought that mock-up T70 turbo and it lasted 2 months.

If you were to get a genuine T70 from garrett, it would be no good on a CA nor a SR or RB20.

Im scoping out the extra cash to get a proper GT30 and tial wastegate as I almost got bitten for that kit.

You have be warned!

Best of luck in making your decision and if you do buy it, let me know how it goes.

"If thats the case, you're going to have more than a CA18 or SR20 to get anywhere near spooling it up."

Really? I know one person that built a Sierra Cosworth 2 litre engine with a Garrett T76, and it made full boost at 5500rpm with a power band from 5500-10,000rpm. Went like the clappers.... and was a very fun car!

Dont forget, people put T88-34d's and HKS T51R SPL's on SR20's and occasionally CA18s as well!

People have had compressor housings on these split in half. They are cheap China made rubbish. Be careful if you’re going to buy a kit.

They are pretty big in the states, some have no problems, and some have all the said problems. I guess you get what you pay for.

As 180bfj20det said :

First off all its not a Garrett T70
I had a T8834D on a 13BT and thats only 1.3L.. meh.

Yer, but rotary engines flow a HEAP more exhaust gas then a piston motor from my beliefs....hence why they run big exhaust housings...cos they can get those big turbos spooling...unlike a ca18 or sr20.

I have heard of an sr20 with a HKS 3037, but it needed a 9,000 rpm limit to get the most out of the turbo....ie a very high rpm drift machine

Ah no that's not actually correct. The 13B is a 6 cylinder 3.9 litre engine and as such has about as much exhaust gas flow as it should. The 1.3 litre is using Mazdas measurements which are factually incorrect. As evidenced by the amount of fuel and air the engine consumes. Consequently it is pretty unrealistic to compare a turbo off a 1.8 or 2 litre with one off a 3.9 litre.:(

That would make sense to me....ive only always hear of rotary engines as mentioned above when regarding their size.....

 

So what are they normally rego'ed as? 4cyl?

In the "Number of Cylinders" box it used to say "N/A", don't know what they use now.:(

They are a 4 cyld but in its own class if ya get me.

alex

Ok, I give up, how do you get 4 cylinders?

My thinking is, they have 2 chambers with 1 rotor in each chamber and each rotor has 3 sides. So it's either 2 cylinder (meaning 1 chamber = 1 cylinder) or its 6 cylinder (meaning 3 rotor sides X 2 rotors).

Personally I reckon it's 6 cylinder.

    • @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣  
    • I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia. 
    • Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.
    • I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).
    • As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
