Intercooler???

[TrbTaLoN]

Ok I drive a 91 tsi awd turbo. I am picking the motor up from the shop next week. I went with the eagle/ross combo .030. I went with all arp hardware throughout the block. Good bye to the balance shafts. The head was also rebuilt bye the shop. I am most likely getting my tranny done by shepracing. Ok well my question is what intercooler. I am getting rid of the 16g for a PTE 50 trim and have been searching for intercoolers. I have heard of people welding two stock smic together and was wondering if this would even come close to being effecient enough for my setup?? I plan on running around 20psi with afc , 660 injectors , a walbro 255 fuel pump, and an adjustable fuel pressure regulator to help out with tuning. I think I have everything in order besides the intercooler so any help or advice would be greatly appreciated.

Thanks

i got a friend thats running 20psi on a stock intercooler ... with upgaded fuel pump and injector with 120k miles on stock internals ... he ran 13.1 last week at houston hrp ... of course he has a big 16g ... but if your going with anything with a faster spool up time than a 16g its recommended that you get some sort of an after market intercooler ...

After having invested in a built motor and buying a real turbo, go with a good intercooler. Intercooling is the key to making power on pump gas.

Don't fvck around when it comes to your cooling. Get a good package from the vendors, or look for a used one in good condition. Spearco core, short rout piping, and you will be a happy man.

Yah I figured two stock smic welded wouldn't be worth the time. It sounded good at the time but that was before I decided on this setup. Just thought I would get some opinions. Hey what size spearco would work out well with the 1g?? Thanks for all you responses.

you built a 6 bolt for a 50 trim?

My buddy picked up a core from the body shop he works at, from a diesel truck, cut off the tanks and had a machine shop weld on nice new end tanks, he has 200 into it, and it is badazz. Plus it fits perfectly because he had the in and out put where he wanted them. You can buy a decent one from ebay for less than 400.00 they are becoming much easier to get.

Used intercoolers can be great. I am using a used ATI 2-core that I picked up for $150. Dimensions are 18x8x3. Good enough for my 14b.

Thanks for the replies and responses. Dsmturboawd what is wrong with building a 6-bolt???

 

[JoeWagon]

He was just saying it's overkill to build an engine just to run a 50 trim.

I'd like to know how well the "bargain basement" cores flow.

Well I don't have numbers, but. . .He has a 92' Toyota Paseo(Don't laugh, he will be in the 13's this year, with a new T25/28 hybrid, 450 injectors and a aeromotive inline fuel pump w/ -6 lines, with a 1.3T motor from a JDM starlet, it originally came with a small top mount, adding the front mount I would guess it made about a 10hp difference (seat of the pants dyno), and is about 3 times the size of the original, which allows boost to be upped to 12 PSI. The core was made by a company out od Britian I believe, who happens to be the premiere intercooler company from there, they build intercoolers for the cool british turbo cars we don't get! This from a ford turbo diesel, the core measures about 24x8x3 it is quite nice, he got the core for free from the body shop he works at, and had a local machine shop fabricate end tanks, 200 bucks and it is nicer than most I have seen, the only problem with it is it doesn't say *Spearco* across the front

fp reds can be run to full potential on a stock 6 bolt motor. people run 50 trims on stock 7 bolts to full potential. why waste your motors potential with a 50 trim?

i just dont get it.

So, you are backing a IC that supports less to around the same power than a 1g makes stock? Super. I'll trust a modded 2.0L turbo engine to that. Another "wierd" thing...my Spearco core doesn't say Spearco. Strange...all the ones on Ebay do.

Neither do I, but that isn't the thread topic.

 

[dsmturboawd]

i guess it's not, just trying persuade a different turbo choice here.

 

[TrbTaLoN]

Yes I see what your saying. I have been reading a lot on the 50trim and from the information that I have gathered it is a good pump gas turbo and since my talon will be a daily driven car I want something that will tune well on pump. The only reason I built the block up was because it was apart and I thought if I am going to do it might as well do it right.Thanks for the responses and any more thoughts on the intercooler or if you know of a better turbo let me know.

Thanks

What should I look for In a good intercooler? Welds? The amount of rows? Overall size?

 

[boostedtalon]

Size is good, but the real issue is flow, how well does it flow, then comes how much surface area is available to cool. Buy a spearco.

With the potential for over 500 whp from a 50 trim I would say it is definitley a good candidate for a built motor. Just check out www.agpturbo.com On the front page they have a 2G running a 50 trim. Dyno'd 503 AWHP on 93 octane. That's very respectable in my opinion. Especially for a motor that will be running primarily pump gas, a 50 trims is defintley a good choice. As they are said to be one of the best pump gas turbos.

 

[dsmturboawd]

just because the shop car put down 503whp doesnt realistically make this a 500whp+ turbo. if you want to look at it like that, the t28 is now an 11 second turbo along with the 14b.

bottom line is building a motor for a 50 trim is over kill.

edit: IMO.

Yeah I see what your saying and it's definitley true. Point made. But of course building a motor while it's apart is always a good idea if you plan on making around twice as much horsepower as was rated from the factory. Which I think might be this guys goal or somewhere around it. Just my opinion.

 

[dsmturboawd]

eh, im in the middle of rebuilding a 6 bolt rigth now. all parts are comming from the dealer. either youre into building the 4g63 or not. im only against them because that really defeats the entire purpose of owning one. stock 6bolt has made sick numbers, and i feel no need to over kill.

just my opinion.

I know your side mount intercoolers are pretty darn good flowing but thats got a lot do with the cfm rate of the turbo you are using stock. Thats how you guys can get 220 whp out of those stock turbos on average boost. BUT when you step up your compressor side up to a huge 50 trim you are increasing the cfm and flow rate of the actual turbo. So a small side mount is no longer acceptable. If your going to spend all that cash on a the engine and whatnot why wouldnt you at least get a decent intercooler? Yes they can be crazy expensive for a bunch of aluminum but you gotta do it right if you've come this far! I would suggest looking into a NPR ic core OR biting the buck and paying for a nice girrfin core intercooler from road race engineering!
