Thats the way,so much easier to upload vids and to comunicate with other race people.
This site is still good for imfo and parts
The motor sounds like a good place to start ditch the turbo slap on some 48mm carbs and your racing.(well nearly anyway)..

Well I guess I will finally have to get on Facebook.

I mentioned the SR20 to my son and low and behold one his friends has a SR20 turbo look block in need of a rebuild. As I would be pulling apart any motor I'd buy this could be the ticket.

Tom you could talk to Ian Caterer on facebook he uses an sr20 with carbs an a distributor and not a lot of money spent but a well sorted car.

Greg thanks; I would likely use the flat slide carbs I have on my A15. I'm likely to get some push back with fuel injection on the car. It also makes it easier for me to tune.

I also have to sheepishly admit that I don't know how the SR20 CAS works; I'm assuming the ECU takes care of the timing advance but again I don't know.

D I have looked at the OZDAT post on the KA head and there is machining that needs to be done. There is also a good bit of mixing and matching to be done. As I'm not likely to be tuning the motor very hard the KAL and SR motor would likely end up with the same power output.

As for Toyota engines I'm pretty sure that would be outside the rules; I don't know of any series that allows this. Most series I've looked up want the same brand of engine.

Starting with a 130-140hp engine and adding headers/extractors cleaning up the ports and up prated cam shafts would likely another 20hp without much trouble.

Toyota Altezza 3SGE Beams Engine 6 spd $1600 usd... CANADA
Altezza is 196 bhp . Think its 142 kg and box 39 kg

SR20DE came out 1990 with 140hp. The roller rocker version came out in 2000 (145hp)

SR20VE came out 1997

Toyo 3S-GE is an awesome Yamaha engine -- except the US version was only 135hp

Tom
Both motors are approved by CAMS to be used in IPRA racing.Some guys put webbers on them to save using expensive computers.And are old school guys like me. Most motors come in silia coupes or 180sx Nissans and there gearboxes are farely strong...Greg.

The 97-98 Toyota beams engine 3S-GE produces 196 bhp and comes with a 6 sp. The Turbo version is 256 bhp . You can pick these up for around $2500 with box and computer. Earlier ones produced more HP.

My brother runs one in his Galant and I must say , very impressive

sr20ve is the roller rocker motor DD
buy a worn sr20de for the number to restamp an sr20ve
if you had to use sr20de block it needs oil injectors
and oil feed for VE head.

Ka24de head is not difficult at all, theres a write up
Ozdat in detail many as you know have dont it and Lampy
had head flowed to result is best flowing 2lt and under
head vs srve etc.

SR is hard to beat weight wise just over 90kg quoted
with carbs or itbs, box is another 15-20kg heavier than t50
Even 8 valve L series can be very powerful and you can
use L28 Turbo zx T5 bellhousing for t5 worldclass box
which is much ligther than 71 series nissan and closer ratios

Theres prob 30kg above an A series for the Sr and you already
have a great differential to suit its torque and BTCC SR engines
all run knife edged crankshafts. I picked 2 sr20de blocks and
could carry one on each arm easily vs one A15 block.
Theres like 15kg difference right there but sr20de head is a
heavy beast so give or take a race A15 is no lighter than race SR

Dave the motor has to be 1999 or older.

D. I'm aware of KA head on L block but that is not a cheap do it in your garage thing.

Vixen are those two motors listed in CAMS / IPRA rule book and can it be accessed online? The key is you have to prove that it was raced in a recognized series.

Here is where I'm at; I'm building up an A15 right now to replace the blown up one, I've sent the cam out to have it ground. The new motor will be slightly higher compression with a slightly more aggressive cam. My thought is it will be pumping out 105-110 at the wheels which is 150% of the original motor stock. As everyone knows I run these things for several and getting more than that means going through the motors annually, which I don't want to do.

My thought is a more modern engine will be much easier to get to the 130-150whp range, I'm the only car in my class at most events but my goal is to get high overall finishes. In the small bore group I run around 5th out of 25th overall and in the B-sedan group I run 9th-10th overall. The B-sedan group is full of 510s and BMW 2002s belting out 175-200whp. If my car were putting out 160-175whp I could probably make the top 3 overall in the B-sedan group.
