Future Engine Mods

[Osmosis]

I"m planing on rebuilding the engine in my Ty this fall. I want as much HP out of this thing as possible, but keepint it stock ....looking, 20g turbo and L35 heads.

I currently have 42lb injectors with code 59 & 3 bar map, Devils own alky injection, KnN air filter, 20g Turbo, gilbert propshaft, engine tie down strap, walbro 255lph fuel pump with hot wire kit, boost gauge and PLX Wide Band, pushing 20 psi of boost.


I want to keep my ty streetable as possible. I had a 91Z that was extremely fast, but I got terrible gas mpg! I drove it hard for 12 miles and it took 4 gallons of gas. That took all the fun out of it.

I"m considering using the stock cam, but I know that the cam should match the heads and I am hoping to use some L-35 heads on this build. If I use the stock cam, should I port the heads? IF so, on which side? My concern is that I don't want the heads to reduce the velocity in the rpm range of the cam/head combo...... IF I should change my cam, I don't want to have a "huge freaking cam" as I've done this before in the past only to KILL my gas mpg. Luckly, when I did put a huge cam in my Z, I had AFR heads that would support the rpm range. Anyway--- my point, or better yet, my question is...

what will be the best cam for the L-35 heads for my future set up. 42lb lucas injectors, 20g turbo and 2800 stall?

L35 heads.....porting. Where should I port these heads? Exhaust side only? Gasket match the intake? I'm used to a NA car so pardon my questions of cylinder head porting, I want to get this right the first time for a turbo charged engine setup

I do plan on using a splay kit for the mains and balancing the engine, worth their weight in gold.

Also, where is the best place to get gaskets for our syty's??? I remember reading that they were no longer making a certain gasket for our trucks?

Thanks for the help all!:tup:

Re: Future Engine Mods

Whats up dude. Well, to start, i would not spend much money on your L-35's, maybe a little bowl work, and better valves, thats it. Cam? i'd go with a 412 comp,but stock is not terrible, maybe some roller rockers. Other than those items, i think you have the right idea. Don't go crazy with it all, unless your gonna go crazy with it all

Hood for gaskets.And btw, tuned, will net you damn good mileage if you do it right, doesn't matter the specs. A heavy foot will always kill dinosaurs.

Sup JP?

Yea, I just want the "perfect combo" for my 20g turbo and the L35 heads. So, it's a matter of finding the right combo for the 14cm exhaust housing on the 20g, l35 heads, 2800 stall and the right cam....now which will make her spool best and produce the best power?

I don't want to spend a mint, cuz if I go vortech heads and all, I'll have to rebuild the tranny a second time. Dont' get me wrong, I want my ty to be fast, low 12's or even mid 11's, but that's it. I hardly drive her, hell, I"ve put a total of 7K miles on her in the 4 years I have owned her.

Re: Future Engine Mods

Look at Tytillidie's original build, his moved pretty good. Like i said above, a 412 and just bowl work on l-35's. 20g will take you far, everything is in the tune

Re: Future Engine Mods

IMO If you have the money, do a set of Vortecs and a mild cam, such as 412 or a mild custom cam. The more air you can move the more hp you will make, but it will also reduce the spool up time of your turbo.

My Syclone has custom cam a little more aggressive than a comp cams 415 and I get the same gas mileage my truck did with stock turbo/cam/heads and i haven't maximized my tune and my torque converter is lock up isn't working either.

Re: Future Engine Mods

I'm running Vortecs with a 412. I'm afraid to check the millage but boy does this thing run. cruise at 60 and in a blink I can be at 80. I have (rarely) pegged the speedo and it's still pulling, scary. ET's in the mid 12's @ 105 with virtually -0- spark retard. No need to go much quicker because it puts me in a different class.

Motor is balanced, Eagle rods, SRP pistions, 2 bolt mains, stock IC with full time pump, built trans, 2800 stall, custom turbo. My heads are port matched only with stock exhaust manifolds and x-over. 3" DP.

Sounds like you're on the right track except for maybe the heads, ijs may be a small depending.:2cents:

There is more info in my thread:

I was able to take my old L35's to a 10.75 pass in a Ty. There is a lot in the tune as well as the combo! Nolab/Campbell's has also been very successful with the L35's and their modded 20g.

Good luck!!

Re: Future Engine Mods

Any update on this Craig? Looks like your setup is pretty much exactly what I want to do. Think I'm gonna add A2A and a bov and 60# injectors also. Keep me updated.
