porting template? which one?

Hey there guys not sure if this is the correct section. Looking to port my 13B, wasn't sure which template I should use though. Pinapple racing or streetbeat?

I'm curious as to the possible power output. I have an 84 GSL-SE with the 13B, i'm unsure of if this is the 6 port or 4 port model. A friend who I bought it from offered to do it as hes very experienced with it.

I want the engine to last but I want at least 200hp to the engine, not sure how much a medium street port would give me.

any input or experience with these templates? thanks in advance

i'm a huge fan of the Pineapple templates and would recommend them to the individual that will do the port work, but doesn't want to mess with making or cutting out their own templates. they are excellent, which is not to criticize those that came before them, but they do have the advantage of being relatively new.

the SE is the original 6-port 13B and 200 HP will be a steep uphill battle for you. you will need to one with putting in a boatload of work and parts with the understanding that you may still never reach it. however, even with 170s to 180s, an SE would be an absolute blast to drive.

Awesome thank you for letting me know on pinapple templates. I will definitely be using them then. But are you sure it's not a 4 port 13b? I think 1984 was the only year with the 4 port. i'd like to at least be in the 6's for 0-60 range at some point. I'd be satisfied there. even with my after market exhaust the car has a significant difference in performance i've noticed.

Any intake recommendations guys? and on the 13b who has the official answer?

nope. SE is a 6-port. your 4 port 13B engines came either before (Rx-4, Rx-5/Cosmo and REPU) or after (every factory turbocharged block).

for me? personally, i would upgrade to Gen II intake and ignition. however, it's not that simple.

what intake would you recommend for an aftermarket?
we were possibly going for an msd ignition. All i want is 200 hp,hell even 180-190.

Can I reach it with a street port, exhaust port and aftermarket exhaust?

i forgot to clarify. you are talking at the wheels, right? because that was my assumption.

honestly, i don't know of anyone who's made 200 on the SE block. that's not the same as saying it hasn't been done though. for what it's worth, it's a little different from the Gen II 6 ports. just putting it out there.

i'm partial to Weber type intakes. there's a Holley available, too, though. however, going aftermarket puts you at a crossroad. are you going carburetor or are you staying fuel injected?

I mean to the block. I dont mean rwhp on this one. I'm fine with either, which would I be able to put more power out with? I have a friend with a 750 double pumper on his 12a, seems like overkill. Being in PA carb isnt ideal but I could live with it as I have a holley on my camaro.

So would say 175 to the wheels be possible and what would it take is basically my question.

13B with a 'mild' sized extend port and opened up exhaust ports, good exhaust system and carb (say 48IDA weber, 38mm chokes with a carter/holley fuel pump) will get you 200hp at the flywheel with no need to go much over 7,000rpm. but you can if you want.

easy to start, slight lump to the idle, will putt around at 2-3,000 rpm no probs and it will love to rev.

exhaust shouldn't need to be too loud, either. it'll make more noise out of the intake when the throttles wide open.

damn i love rotaries, if i didn't already own one i'd be buying one after typing the above.

so carburetor then, eh? RB claimed their old Dell'Orto systems were good for roughly 175 (flywheel) with their long exhaust system. with porting, 30 years of other tricks here and there, there's no reason you shouldn't be able to exceed that with a decently matched carbie, exhaust and some good tuning.
