j35a8 aint nowhere near b18c5... so I doubt this sohc head would hold up to anything above 4psi stock... but hey I would love to see the numbers...

 

+1

=) S/C helps a lot here!

killed a few 335i on the highway =) doesn't seem too hard lol

 

it would be stupid to do so.... compression of something like 10.5 or 10.6 running that boost... or wellz.. not really stupid... but rather.. how many laps can you track that engine before it goes KAAAA-BOOOOOM


and also... you have to consider whether the block is open deck or close deck....

=)

 

Hey guys I was wondering if there was immediate interest for more? I can have 20 more sets here in 10 days.

 

The new Redline9 forum is doing a group buy on turbo kits for the J32 right now as I recall.

http://www.redline9.com/the-j32a-tur...ler-t-843.html

 

yeah there is interest for more.....Let me know when you get more in? and question richie v6 if i bought the j pipe from you and test pipe how much are these precat deletes?

 

richie blew this guys bubble, isn't he using cheap china crap...?

 

What would happen if you just "punched-out" the inside of the CATs.

Please direct me to the right thread if its here. My son has been looking for days now. We used to do it on old Ford Mustangs. It had 4 total and we'd punch them all with no issues, but it had the old OBD-I in 1992.

 

It will cause some major loss of power... The tl has 3 cats...

$900+ in price

Gutted primaries will create some major bottle knecking as they are about 3.4" at the widest point and go down to 2" on the outlet

Not reccommended and ill advised

Precats are cheaper in price than the 3rd oem cat... Just some fyi before you go gutting expensive cats

 

From reading the thread...yes....thats what it appeared to me. Is Richie coming out with a turbo kit? Havent seen that one yet.

 

Dont worry you will get a good deal.

 

as for now it is just in chit chat stage... would be hot though

 

Gutting a cat is not practical since you are destroying something worth at least 3 times a set of precat deletes. The large open area of the empty cat would slow down the exhaust flow, and the the smaller outlet of the cat would cause bottle necking. causing the lost of power. A straight pipe is the best bet it gets the exhaust gases out quickly without restriction.

 

I don't understand how the design of the head would have anything to do with the "strength" of the engine. Boost dosn't blow up heads, headgasket's yes.

4psi ?? A 3 cylinder geo can handle that. No one has really tested the strength of the bottom end yet but I wouldn't see why it wouldn't EASILY handle 10lbs with tuning. 10lbs figure maybe 100crank hp, extra 16-17hp per cylinder, if that snaps rod's or blows the piston's I need to sell my car soon before I mod it more.

Never seen a closed deck aluminum block. Especially from Honderr

 

I have not installed these yet but when I install the Pre Cat deletes and J-pipe I should not have the CEL come on right?

However if it does that is corrected by resetting the ECU and disconnecting the battery, correct?

I am also waiting on the Hi-flowing cat to reduce some potential bottlenecking since I am keeping the stock exhaust for now.

So my R-V6 test pipe will be in the BM soon!

Also one question if I decide on running a resonated catback exhaust system in the near future that will be fine right, no negative consequences?

Thanks for all your help. I appreciate your comments.

 

just make sure you disconnect your battery before doing anything on your car and there will be no CEL.

 

Wll, dont forget this engine is a very HIGH c/r.... 11:1

Two members blew their engines when running the HBP (hi-boost-pulley) which i believe, only runs at like 9lbs of boost....

you would definitely need some serious engine/machining work to run hi-boost on this application... new rods, pistons, maybe some sleeves done.... i think these engines are like ALREADY at their maximum tune/capabilities.. and anything else is really stressful on them...

ive actually been looking into ripping apart my block, and finding some work i can do in there.... we'll see how that goes....

 

Yes the CR is up there, but there's plenty of boosted b series & k series that have close to that CR and manage fine and their four cylinders.

I do agree that you wouldn't be able to run "high" boost but 10-12 I see being completely possible with stock piston's & rods. Also don't forget methanol injection isn't very expensive and has incredible results and then there is always race gas.

Tuning is our issue , hopefully the other thread you started will soon allow for some good tunes for the SC guys.

As for the two members that blew them up, was the cause determined ? Pre-Ignition? Melted pistons? Snapped rod? My guess would be tuning related.

I wouldn't see why this engine couldn't handle 400whp without many reliability issues. We'll have to see, if they made a blower setup for the type-s I'd be a martyr

 

^ ok then, start with this:
http://www.redline9.com/the-j32a-tur...ler-t-843.html

good luck...

 

ugh. what a PITA to intall these damn things

the sound... incredible... the rasp... its there.... noticeable.. but whatever

the smell, not that bad... i still have stock 3rd cat in place

 

I totally agree. The TL crowd seems to know nothing about tuning. I don't think the blown motors are from too much power but rather detonation. If you run the HBP, either run 100 octane or get methanol injection. There is no reason the TL shouldn't be able to make 400hp on stock internals. Like I mentioned before, I blew up a couple motors in the Buick when I was in the 12s and now that I'm pretty good at tuning I haven't hurt anything running in the 10s still using stock parts.

11.0:1 just increases the octane requirement people. You will make more power per psi of boost, you just need more octane for the amount of boost.

 

finally sheeeeeeeesh...

top end is insane right... question WTF stock 3rd cat? bottleknecking

 

finally sheeeeeeeesh...

top end is insane right... question WTF stock 3rd cat? bottleknecking

 

^ yea definitely some bottle necking... no test pipe for me.. if richies hi-flo is 2.5" all around/ 300 cell (like planned) i might get it.. expensive, yes.. but ya know what, it will help the flow, and still regulate some type of emissions


heres my on the Precats. drove like 40 miles today on them

Low end.. no "loss" of power, but the throttle response changed DRASTICALLY.. on my setup at least.... the power gains are there, but you have to FORCE them out... what do i mean?

Well, say you are cruising at like 40mph... and you want to give a little bit of gas to speed up... the amount of gas you usually apply for a subtle increase, wont get the car moving the same as you are used to.... it takes a little more ummphh

BUT, when you give it the little extra kick, it takes off WAY more than it used to... the top end power truely is noticeable...

worth the money in my opinion, but man, what a bitch to change... not pleasant.... removing brackets, and covers, and fans, and hanging the j-pipe down... those gaskets that are on the block, man, they are RAZOR SHARP... cut ya' right open.. like a nasty-ass papercut


i need to dyno again, but i wanna take my wheels off before i do (riding on the 20's again)... and wait for slightly cooler temps.. so i can compare to my dyno in May

Mine do actually have a pretty nasty rasp between 2k-3k accelerating...

 

honestly... that slight delay in umph might just be from your stock cat... I am rolling in my wide summer setup and my tires brake loose vsa on, without having to floor it... I think its your 20" wheels... heheheh still waiting on you to reup... no one's bought those yet?

as for cutting urself with the precat gasket... aint you wear gloves hommie

 

^^ haha i didnt cut myself, the guy working on the car with me did

 

Al

What did you do with the bracket that held the rear cat to the car? there was obviouly no place to put it on the precat delete.. so i took it off

I am getting either a rasp, metal rattle or something... when im at like 2k RPM going upward strongly, i hear it.. it sounds cheap.. .and "tin-ny"

you guys having that problem?

 

yea, ive had somebody stop me to tell me i had a bad rattle coming from my car lol. Its just a rasp i believe.

 

I took that bracket off when I installed my procats back in january... It is the halfshaft heatshield, If you are getting a vibration put the car on a lift while its on and see where its coming from

I have not 1 single noise

It could also be ur stock 3rd cat going rofl (imagine)

Also james if you've got a rattle it could be that same spot I removed a heatsheild from above the catback

As for me, I had a slight vibration which I believe was coming from one of the 2 flex sections... A little carbon buildup and no rattles here... As for rasp... 5k+ rpms... Sounds dead sexy... At idle? Sounds like a diesel

 

High flow cats are coming I am getting a lot professionally welded soon. I am getting 6 made I know at least 3 are spoken for.

I get a nastyyy rasp between 2700 - 3000 RPMs.. I hate it, I feel like a ricer in a $10K car but other than that it sounds good. I love the gains. Im lookin into a resonator or something because its annoying the hell outta me.

 

RV6, don't forget about me!

 

rasp ftl

 

hopefully the cat fixes all the rasp problems.

 

You guys with "rasp" you might want to check if there is clearance bettween the rear delete and the heat shield over the intermediate shaft.

 

Well, wouldnt there be more clearance? because these are so much smaller then the stock cats w/ their heatshields on?

Mine is bad... i dont think its rasp... its a metal rattling sound....

it actually sounds...well..... like a heat shield ... ya know when like a cars exhaust heatsheild rattles ? i gotta find a solution for it... its driving me nuts

the exhaust note (when not rattling/rasping) is sa-weet. i didnt think my setup could get any louder and deeper.. but it did

 

Try removing the heat shield around the intermediate shaft. (where the dent is)

 

Allon.. I can take a look at it for you if you want

Might drop by wanderer's crib... Let me know


Ps. The rasp is from no resonator heheh, I've got one... So I get rasp way uptop aswell as backfire hehehe sounds so awesome...

 

hmm... will check that out this weekend
