H/C/I swap

[IT_SS]

First and for most, i know you gurus are tired (as hell) of people asking this question and i want to apologize in advance for asking this. But is the TSP H/C package ( http://www.texas-speed.com/shop/item...d=203&catid=15 ) better than whats offered by TrickFlo ( http://www.trickflow.com/partdetail....autoview=sku)? The TSP package is cheaper, but the TrickFlo seem to be all the rage. I know the TSP produces a higher compression ratio (10.6:1(TFS) vs 10.75:1(TSP)) but should that be a determining factor?

And also, what supporting mods/preventive maintenance should i look in to since the engine will be out of the car. And any objection towards a tubular K-Member?

thanks again

and fyi, my rwhp goal is 440-500hp with FAST 90/90 (92 seems a bit excessive) QTP LTH, QTP Catted Y pipe and GMMG cat back exhaust

[IT_SS]

any body?

If I choose between the two I would go with the TF. Heard lots of good things about oth of them, but TF seems to be popping up alot.

What cam were you planning on going with TSP???

TF was using the 228. Which is a great cam.

On your intake, 90/90 and 92/92 are almost exactly the same. Only the mouth is bigger on the 92. 2 mm aint nothing... The runners are the same.

Personally I believe the Trick Flows have more potential for power, and I would hope so since they cost so much more. The difference in between the two heads can even be made the same with a little machine work.

As for what cam to match up to them I would do alot of research and question asking. See what cam's are suggest by custom cam grinders and speed shops.

I would also get a LS2 timing chain, Ported oil pump, and LS7 racing lifters while you are doing a head and cam swap. You will absolutely need springs that can handle your cam, but that will be determined by your goals for the car and might even come with the heads when you buy them.

I think the Fast 92/92 replaced the Fast 90/90.

[Bouvers]

I think the Fast 92/92 replaced the Fast 90/90.

indeed it did... the only way you can get a fast90/90 now is used...

[Hi-Po]

I think the Fast 92/92 replaced the Fast 90/90.

It did, but there are minor revisions to it. One being a 2mm larger mouth. Hardly anything to sway one's mind. If someone can find pictures of the inside runner of a 90mm I have plenty on pictures of a 92. Im pretty sure they are the same inside.

I'd go TSP. Not sure the price difference as the Trick Flow link didn't say but I'm guessing something like $1,000.

[Mr. Luos]

I am a really big fan of TSP personally. Always treated me very well.


No experience with TrickFlow.

Mr. Lous, you spraying the car or all motor?

All motor.

im really geard twords the TSP stage 2.5 Heads with the 233/239 113lsa cam (street manners matter to me!!!)

Mr. Luos, did you have TSP do and thing xtra to the heads? I want to get the most bang for my buck, and will the LSA remedy the rough idle? i dont want anything too radical

[Mr. Luos]

I had TSP build the shortblock.
They didn't touch the heads. I did all that.

Tune is the key to idle and driveability.

So roughly, i think i can make about 450 @ the wheels with the TSP Stage 2.5 Heads, 233/239 113LSA Cam, FAST 92/92 combo, QTP LTH and Catted YPIPE, GMMG CB, and the supporting mods and a really good tune

[Mr. Luos]

Maybe.

Try not to focus on peak numbers so much though. Power under the curve is where it is at.

[IT_SS]

i hear you on that brother, and thanks, youve been helpfull

[Frost]

SCR isn't fixed, just mill the TFS's; why install them without? It's like giving away an increase that costs next to nothing...

i was at 443/402 with Patriot Stage II heads (59cc) and a little Comp 224 cam, Lt's, TSP TD's, FAST 90/90...

OP, your goal is obtainable with the right parts and a strong tune...
